    A series of 16 cases of intracerebral hemorrhage associated with brain tumors are described. The literature is reviewed and the incidence of these cases is reported to be low, but we had clinically encountered these cases more commonly than reported, since CT was introduced to the neurosurgical field as a diagnostic aid. The presenting symptoms were those of spontaneous intracerebral hemorrhage or brain tumor. The intracerebral hemorrhage associated with brain tumor may mask the cause of bleeding and confuse the diagnosis. The majority of the tumor causing the intracerebral hemorrhage are highly malignant as glioblastoma or metastatic brain tumor, but there are some benign tumors such as pituitary adenoma, hemangioblastoma, benign astrocytoma and meningioma, which would have good survival rates if discovered early. The mechanisms of massive hemorrhage with brain tumor are not clear. From pathological findings of our cases and other reports, the mechanism seems to be due to the vascular endothelial proliferation with subsequent obliteration of the lumen of the vessel. Thin walled, poorly formed vessels in tumor may also become distorted with growth of the tumor and these may easily rupture and bleed. Necrosis with subsequent loss of vessel support may be a factor in production of hemorrhage. Radiation therapy may be a predisposing factor. Children are rarely involved in these cases. The prognosis in the majority of cases would seen to be poor, since the majority of the tumor are highly malignant and most such patients are seen by the neurosurgeon some time after the hemorrhage has accomplished its fatal mischief.

    Cases of intracerebral hemorrhage except typical putamen thalamic hemorrhage were reported. It is not difficult to diagnose typical attacks of cerebral apoplexy in patients older than 40 years with hypertension by CT. When the condition of the onset is not typical, cerebral infarction must be considered. Though conservative treatment is performed for severe cerebral hemorrhage and cerbral infarction, there is no specific medicine curing these diseases completely. On the contrary, the risk that the administration of fibrinolysis activators and STA-MCA anastomosis may induce cerebral hemorrhage is stressed. Not a few patients with cerebral apoplexy accompanied by small hemorrhagic focuses have been found, especially since CT was used widely. However, treatment for this disease has many inconsistencies. From above-mentioned facts, we recognize excellent roles of CT in an application of surgery for cerebral hemorrhage of early stage, and we, general radiologists, are under an obligation to advise most adequate theraphy for each patient.

    The magnetic resonance imaging (MRI) of intracerebral hemorrhages (lateral type) was studied. The strength of the magnetic field was 0.2 Tesla. Four cases were studied with inversion recovery (IR) and saturation recovery (SR) images. The findings of the acute stage (within 1 week) were a central isointensity and a peripheral low intensity on the IR image. On the SR image we recognized a central isointensity and a peripheral high intensity holding a faintly high intensity area around the hematoma. The findings of the subacute stage (from 1 to 3 weeks) were characterized by a central isointensity and a peripheral high-intensity ring, with a low-intensity area outside the hematoma on the IR image. A widespread high-intensity area including the hematoma itself and the surrounding white matter was observed on the SR image. The findings of the chronic stage (over 3 weeks) were the disapperance of a high-intensity ring and a change to a low-intensity area on the IR image. The hematoma itself and surrounding white matter had a high intensity, which has decreased in size in comparison with that of the subacute stage. The hypointensity rim was found in the immediately adjacent part of the original hematoma on the SR image. The MRI of a small hematoma 70 days from the onset showed an almost normal brain structure. Some magnetic resonance findings of intracerebral hemorrhage were reviewed. (author)

    Full Text Available Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate secondary injury. Deep knowledge of the injuries which are directly involved alterations of glucose, offers insight as cytotoxicity, neuronal death and metabolic dysregulations alter the prognosis of patients with spontaneous intracerebral hemorrhage.

    Only vague guidelines exist for the surgical management of intracerebral hemorrhage (ICH). We investigated the indications for surgical management of intracerebral hemorrhage and compared the outcomes of computed tomography (CT)-guided stereotactic hematoma aspiration with those after hematoma removal under craniotomy. Our indications for CT-guided stereotactic hematoma aspiration were an age < 80 years old, a hematoma volume ≧ 10 ml, and a Glasgow Coma Scale (GCS) score ≦ 14. Those for hemat...

    Previous studies of pediatric intracerebral hemorrhage have investigated isolated intraparenchymal hemorrhage. We investigated whether detailed assessment of intraventricular hemorrhage enhanced outcome prediction after intracerebral hemorrhage. We prospectively enrolled 46 children, full-term to 17 years, median age 2.7 years with spontaneous intraparenchymal hemorrhage and/or intraventricular hemorrhage. Outcome was assessed with the King’s Outcome Scale for Childhood Head Injury. Twenty-six (57%) had intraparenchymal hemorrhage, 10 (22%) had pure intraventricular hemorrhage, and 10 (22%) had both. There were 2 deaths, both with intraparenchymal hemorrhage + intraventricular hemorrhage volume ≥4% of total brain volume. Presence of intraventricular hemorrhage was not associated with poor outcome, but hydrocephalus showed a trend (p=0.09) toward poor outcome. In receiver operating characteristic curve analysis, combined intraparenchymal hemorrhage + intraventricular hemorrhage volume also showed a trend toward better outcome prediction than intraparenchymal hemorrhage volume alone. Although not an independent outcome predictor, future studies should assess intraventricular hemorrhage qualitatively and quantitatively. PMID:22068828

    Cerebrovascular diseases are important causes of death in patients on maintenance hemodialysis. Recently, it has become clear that the presence of cerebral microbleeds (MBs) on T2 * -weighted magnetic resonance imaging (MRI) is closely related to intracerebral hemorrhages. This study investigated the incidence of MBs in chronic dialysis patients and prospective hemorrhagic complications of chronic dialysis patients with old intracerebral hemorrhages. Eighty patients (34 males, 46 females) with chronic renal failure, whose mean age was 62.9±11.4 years, were examined by MRI. The mean duration of hemodialysis was 7.8±6.3 years. MBs were found in 28 patients (35%) by T2 * -weighted MRI. Old intracerebral hemorrhages were seen in seven of the patients, and MBs were found in five (71%) of these seven patients. The frequency of old intracerebral hemorrhages was significantly higher in patients with MBs than in those without (p=0.048), and the numbers of MBs were significantly larger in patients with old intracerebral hemorrhages than in those without (p=0.0065). Three of the seven patients with old intracerebral hemorrhages had new hemorrhagic complications (two intracerebral hemorrhages and one cerebral microbleed) within a year. These intracerebral hemorrhages occurred in areas without MBs on the first T2 * -weighted MRI. T2 * -weighted MRI is useful for the detection of MBs, which may be a predictor of intracerebral hemorrhage. When a patient has a large number of MBs and old intracerebral hemorrhages, the risk of intracerebral hemorrhage undoubtedly increases. (author)

    Full Text Available Brain tumors with concomitant intracerebral hemorrhage are rarely encountered. Hemorrhage as the initial presentation of a brain tumour may pose some diagnostic problems, especially if the tumour is small or the hemorrhage is abundant. We present a 47-year-old man who admitted to the emergency department with sudden onset headache, right blurred vision and gait disturbance. A non-contrast cranial computerized tomography scan performed immediately after his admission revealed a well circumscribed right occipitoparietal haematoma with intense peripheral edema causing compression of the ipsilateral ventricles. On 6th hour of his admission the patient%u2019s neurological status deteriorated and he subsequently underwent emergent craniotomy and microsurgical evacuation of the haematoma. The histopathological examination of the mass was consistent with a glioblastoma multiforme. Neoplasms may be hidden behind each case of spontaneous intracerebral hemorrhage. Histological sampling and investigation is mandatory in the presence of preoperative radiological features suggesting a neoplasm.

    The victim, 52 year old man, was thrust down and hit his left occiput against the concrete floor. He was hospitalised and his comatose state continued to the death. On admission, blood pressure was 212/110 mmHg and the computed tomography scan of the head showed only an extensive right subdural hematoma. But the intracerebral hemorrhages in the right frontal, temporal and parietal lobes were recognized 10.5 hours after the trauma. A subdural hematoma was evacuated by operation on the second hospital day. The intracerebellar hemorrhage also appeared 16 hours after the trauma. Blood pressure fluctuated between 160/80 and 200/110 mmHg. The photo of CT scan at 38.5 hours after the trauma showed little subdural hematoma and new intracerebral hemorrhage located in the left temporal lobe. On the third hospital day, he was equipped with a respirator and blood pressure was between 132/84 and 242/100 mmHg. The reaction of the pupils to light disappeared on the 8th hospital day. Blood pressure gradually decreased on the 9th and 10th hospital days and he died on the 11th day. Autopsy revealed a bruise in the left occiput, a linear fracture in the frontal and left parietal bones and a small amount of subdural hematoma on the surface of the right cerebral hemisphere. Cortical contusions were found in the right frontal, the both temporal and the left parietal lobes. Intracerebral hemorrhages were found in the right frontal, the both temporal and the right parietal lobes. Intracerebellar hemorrhage was also found. Cardiac hypertrophy and atherosclerosis of the aorta were recognized. We thought that small hemorrhages which were not clearly detectable by CT scan immediately after injury may have developed into massive intracerebral and intracerebellar hemorrhages due to high blood pressure after a hospitalization.

    Intracerebral hemorrhage (ICH) is a subset of stroke due to bleeding within the parenchyma of the brain. It is potentially lethal, and survival depends on ensuring an adequate airway, reversal of coagulopathy, and proper diagnosis. ICH was chosen as an Emergency Neurological Life Support protocol because intervention within the first critical hour may improve outcome, and it is critical to have site-specific protocols to drive care quickly and efficiently.

    Full Text Available Objective To analyze the clinical features of multiple spontaneous intracerebral hemorrhages (MICH. Methods Conservative therapy, puncture and drainage, hematoma removal and/or decompressive craniectomy were used in the treatment of 630 intracerebral hemorrhage (ICH patients, who were divided into 2 groups: 30 cases with MICH and another 600 cases with solitary intracerebral hemorrhage (SICH. Three months after onset, modified Rankin Scale (mRS was used to evaluate the prognosis of all cases. Results Compared with patients in SICH group, the occurrence rate of hypertension > 5 years (P = 0.008, diabetes mellitus (P = 0.024, hypercholesterolemia (P = 0.050 and previous ischemic stroke (P = 0.026 were all significantly higher in MICH group. The mean arterial pressure (MAP level (P = 0.002 and the incidence of limb movement disorder (P = 0.000 were significantly higher in patients with MICH than those with SICH. Basal ganglia and thalamus were the predilection sites of hematoma (P = 0.001. Patients with MICH had worse prognosis compared to those with SICH 3 months after onset (P = 0.006. Conclusions Hypertension > 5 years, diabetes mellitus, hypercholesterolemia and ischemic stroke were identified to be the pathophysiological basis of MICH in this study. All patients with MICH had more serious clinical manifestations after onset and worse prognosis. DOI: 10.3969/j.issn.1672-6731.2016.01.008

    It is generally accepted that cases of aphasia can be divided into several groups according to verbal fluency, auditory comprehension, and repetition abilities. Although many authors have studied aphasia and its location by means of a CT scan, the primary lesion on a CT scan with regard to the subtypes of aphasia still remains controversial. In this report we present our new CT classification for the syndromes of aphasia and the prognosis. Twenty-one patients with intracerebral hematoma (ICH) were followed up for more than 3 months after onset. ICH was classified according to the mode of the horizontal extension of the hematoma on a CT scan. Four lines were decided as follows: Line (a) is between the anterior horn of the lateral ventricle and the midpoint of the third ventricle; Line (b) is the vertical line to the saggital line which originates from the midpoint of the third ventricle; Line (c) is between the trigone of the lateral ventricle and the midpoint of the third ventricle. The CT classification consisted of 4 types: in Type A, ICH was located anterior to line (a); in Type B, ICH was located between line (a) and line (b); in Type C, ICH was located between line (b) and line (c); Type B+C, was a combination of Type B and Type C. Transcortical motor aphasia belonged to the Type A group. Transcortical sensory aphasia belonged to the Type B and Type B+C groups. Wernicke's and anomic aphasia belonged to the Type C group. Conduction and global aphasia belonged to the Type B+C group. Pure Broca's aphasia could not be observed in this series. Several relationships between the syndromes of aphasia and its CT findings were evident. On the other hand, the syndromes of aphasia and the degree of recovery were not correlated, except for global aphasia. (author)

    Cerebral hemodynamics in 15 patients with hypertensive intracerebral hemorrhage (HICH) were evaluated by measuring cerebral blood flow (CBF) and cerebrovascular reserve capacity, using stable xenon-enhanced computed tomography. Their hematomas were removed by stereotactic aqua stream aspiration. The hemispheric and thalamic CBFs of patients with HICH were lower than those of hypertensive patients without hematomas. However, the hemispheric CBF increased according to how much of the hematoma was removed surgically. Thus, hemodynamics in patients with HICH can be improved by surgical hematoma removal, although some adjunct therapies are necessary in order to prevent secondary edema and the delayed neuronal death.

    Nonbacterial thrombotic endocarditis is a rare cause of valvular heart disease, most commonly associated with advanced malignancy. The morbidity of this kind of endocarditis lies in its tendency to embolize, while the valve function is usually preserved. The central nervous system is the most common site of embolization, leading to ischemic stroke. We report a case of nonbacterial thrombotic endocarditis complicated by intracerebral hemorrhage as the first manifestation of adenocarcinoma of the lung. The endocarditis led to severe aortic regurgitation. In view of the advanced stage of lung cancer, the patient refused further therapy. He passed away 3 weeks after first diagnosis of the adenocarcinoma.

    Hemorrhagic stroke is a common and severe neurological disorder and is associated with high rates of mortality and morbidity, especially for intracerebral hemorrhage (ICH). Increasing evidence demonstrates that oxidative stress responses participate in the pathophysiological processes of secondary brain injury (SBI) following ICH. The mechanisms involved in interoperable systems include endoplasmic reticulum (ER) stress, neuronal apoptosis and necrosis, inflammation, and autophagy. In this review, we summarized some promising advances in the field of oxidative stress and ICH, including contained animal and human investigations. We also discussed the role of oxidative stress, systemic oxidative stress responses, and some research of potential therapeutic options aimed at reducing oxidative stress to protect the neuronal function after ICH, focusing on the challenges of translation between preclinical and clinical studies, and potential post-ICH antioxidative therapeutic approaches.

    We studied 235 patients with hypertensive intracerebral hemorrhage by CT for about five years. An acute intracerebral hematoma is characterized by sharply delineated high density area. Repeated CT examinations demonstrate reduction in size of the high density hematoma after intervals of 20 - 40 days. And then, in general, the areas formerly occupied with hematoma show normal or reduced density. One or two days after hemorrhage, the high density is surrounded by a thin low density zone. After a few days the low density area is seen at the anterior and posterior pole of the high density in the white matter. These low density are produced by edema or resolving hematoma. About five days after hemorrhage, high density area is associated with wide surrounding low density zone of edema and then gradually diminishes in size. The wide low density zone surrounding the high density of hematoma persisting for over 15 days is probably composed not only of edema, but also of liquefied hematoma, necrotic brain tissue and so on. Enlarged hematoma and surrounding low density area extend to anterior, posterior, superior and inferior direction in the white matter. CT studies with i.v. contrast enhancement demonstrate from the 2nd to 4th weeks a ring-shaped high density around the hematoma. We classified each of the putaminal and thalamic hemorrhage into four types based on CT findings of hematoma advancement. In this study, a statistical method of Speareman's coefficients of rank correlation was utilized. According to this investigation, the important factors influencing prognosis and operative results were found to be the CT findings including the location and size of a hematoma, as well as the rapidity and the direction of its evolution.

    Full Text Available Hyponatremia is the most frequently encountered electrolyte abnormality in critically ill patients. Hyponatremia on admission has been identified as an independent predictor of in-hospital mortality in patients with spontaneous intracerebral hemorrhage (sICH. However, the incidence and etiology of hyponatremia (HN during hospitalization in a neurointensive care unit following spontaneous intracerebral hemorrhage (sICH remains unknown. This was a retrospective analysis of consecutive patients admitted to Detroit Receiving Hospital for sICH between January 2006 and July 2009. All serum Na levels were recorded for patients during the ICU stay. HN was defined as Na <135 mmol/L. A total of 99 patients were analyzed with HN developing in 24% of sICH patients. Patients with HN had an average sodium nadir of 130 ± 3 mmol/L and an average time from admission to sodium <135 mmol/L of 3.9 ± 5.7 days. The most common cause of hyponatremia was syndrome of inappropriate antidiuretic hormone (90% of HN patients. Patients with HN were more likely to have fever (50% vs. 23%; p = 0.01, infection (58% vs. 28%; p = 0.007 as well as a longer hospital length of stay (14 (8–25 vs. 6 (3–9 days; p < 0.001. Of the patients who developed HN, fifteen (62.5% patients developed HN in the first week following sICH. This shows HN has a fairly high incidence following sICH. The presence of HN is associated with longer hospital length of stays and higher rates of patient complications, which may result in worse patient outcomes. Further study is necessary to characterize the clinical relevance and treatment of HN in this population.

    Objective: To determine the association of ultraearly hematoma growth (uHG) with the CT angiography (CTA) spot sign, hematoma expansion, and clinical outcomes in patients with acute intracerebral hemorrhage (ICH). Methods: We analyzed data from 231 patients enrolled in the multicenter Predicting Haematoma Growth and Outcome in Intracerebral Haemorrhage Using Contrast Bolus CT study. uHG was defined as baseline ICH volume/onset-to-CT time (mL/h). The spot sign was used as marker of active hemorrhage. Outcome parameters included significant hematoma expansion (>33% or >6 mL, primary outcome), rate of hematoma expansion, early neurologic deterioration, 90-day mortality, and poor outcome. Results: uHG was higher in spot sign patients (p 4.7 mL/h (p = 0.002) and the CTA spot sign (p = 0.030) showed effects on rate of hematoma expansion but not its interaction (2-way analysis of variance, p = 0.477). uHG >4.7 mL/h improved the sensitivity of the spot sign in the prediction of significant hematoma expansion (73.9% vs 46.4%), early neurologic deterioration (67.6% vs 35.3%), 90-day mortality (81.6% vs 44.9%), and poor outcome (72.8% vs 29.8%), respectively. uHG was independently related to significant hematoma expansion (odds ratio 1.06, 95% confidence interval 1.03–1.10) and clinical outcomes. Conclusions: uHG is a useful predictor of hematoma expansion and poor clinical outcomes in patients with acute ICH. The combination of high uHG and the spot sign is associated with a higher rate of hematoma expansion, highlighting the need for very fast treatment in ICH patients. PMID:27343067

    Cerebral amyloid angiopathy (CAA) is an important cause of lober intracerebral hemorrhage in the elderly. Although leptomeningeal and cortical arteries with the deposition of the amyloid β-protein (Aβ) have been thought to rupture in CAA, the pathogenesis of CAA-related hemorrhage still remains obscure. We studied 10 cases of CAA according to the Boston criteria from April 2006 to July 2009 in Omaezaki Municipal Hospital. Based on clinical data, we examined the primary site of hemorrhage and hypothesized the mechanisms of bleeding. Intracerebral hematoma evacuation was performed to alleviate neurological deteriolation in 2 patients and to make diagnosis in 3 patients. The surgical specimens were pathologically examined. The characteristic MR images of CAA related hemorrhage were characterized by microbleeds, superficial siderosis, subpial or subarachnoid hemorrhage, subcortical hemorrhage and lober intracerebral hemorrhage. Chronological images obtained in 1 patient revealed that lober intracerebral hemorrhage developed from microbleed with subpial hemorrhage without subarachnoid hemorrhage in one side of the cortex in the affected facing cerebral sulci. Operative findings showed subpial and subarachnoid hemorrhages around the cortical veins on the affected cerebral sulci in all cases. Abnormal fragile vessels existed in one side of the cortex of the affected sulci but not in the other side of the cortex. Complete hamatoma evacuation was performed in 4 cases. The surgical specimens of the hematoma and the adjacent brain parenchyma were pathologically examined by tissue staining with hematoxylin-eosin and Congo red. Many vessels in subpial, subcortical and subarachnoid space along the cerebral sulci were deposited with Aβ. From these findings, we speculated that the primary hemorrhage related to CAA occurred from the cortical arteries with Aβ deposition in the subpial space along the cerebral sulci and formed a lober intracerebral hematoma.

    The purpose of this study was to analyze the angioarchitectures of cerebral arteriovenous malformation (AVM) and to determine whether there was correlation between angioarchitectures and patterns of intracranial hemorrhage (intracerebral, intraventricular, and both) in cerebral AVM. One hundred and twenty-eight patients who between November 1989 and December 1994 suffered supratentorial AVM with intracranial hemorrhage were studied retrospectively. Among 128 patients, intracerebral and intraventricular hemorrhage were seen in 68(53%) and 24 patients(19%), respectively, while both types were seen in the remaining 36 (28%). We analyzed the angioarchitectual characteristics of AVM, namely nidi, feeding arteries and draining veins, in three hemorrhagic groups of patients with intracerebral hemorrhage, intraventricular hemorrhage and both. The X 2 test or Fisher's exact test was used for statistical analysis. A cortically located nidus was most common in patients with intracerebral hemorrhage, while a periventricular location was most common in those with intraventricular hemorrhage (p<0.001). Location in the corpus callosum, choroid plexus, or intraventricular area was more frequent in the intraventricular than the intracerebral hemorrhagic group (p<0.05). Superficial venous drainage was most common in patients with intracerebral hemorrhage (p<0.001), and deep venous drainage in those with intraventricular hemorrhage (p=3D0.001). The angioarchitectual characteristics of cerebral arteriovenous malformation correlate significantly with patterns of intracranial hemorrhage, and awareness of the type of hemorrhage could help to manage patients and determine prognosis.=20

    Intracerebral hemorrhage (ICH) is one of the most detrimental sub-types of stroke and accounts for 10-15% of all strokes Qureshi et al. (Lancet 373(9675):1632-1644, 2009). ICH has an incidence of 10-30 cases per 100,000 people/year which is increasing and expected to double by the year 2050 Qureshi et al. (N Engl J Med 344 (19):1450-1460, 2001). Mortality rates still remain poor (30-50%) and functional dependency after ICH is high (~75%) van Asch et al. (Lancet Neurol 9 (2):167-176, 2010). Up to now, all randomized controlled trials investigating treatment approaches in ICH have failed to document improvements on clinical endpoints Mayer et al. (N Engl J Med 358 (20):2127-2137, 2008); Brouwers and Goldstein (Neurotherapeutics 9 (1):87-98, 2012). Only a specialized treatment of severely injured patients at dedicated neuro intensive care units [NICU] has been shown to be beneficial Qureshi et al. (Lancet 373(9675):1632-1644, 2009); Suarez et al. (Crit Care Med 32 (11):2311-2317, 2004). Currently, ongoing trials are investigating aggressive blood pressure lowering, hemostatic therapies, different operative strategies, intraventricular thrombolysis as well as neuroprotective approaches, and brain edema therapies. This review will summarize advanced treatment strategies and novel approaches which are currently under investigation.

  12. Hematoma Expansion Following Acute Intracerebral Hemorrhage

    Intracerebral hemorrhage, the most devastating form of stroke, has no specific therapy proven to improve outcome by randomized controlled trial. Location and baseline hematoma volume are strong predictors of mortality, but are non-modifiable by the time of diagnosis. Expansion of the initial hematoma is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for hematoma expansion have been identified, including baseline ICH volume, early presentation after symptom onset, anticoagulation, and the CT angiography spot sign. Although the biological mechanisms of hematoma expansion remain unclear, accumulating evidence supports a model of ongoing secondary bleeding from ruptured adjacent vessels surrounding the initial bleeding site. Several large clinical trials testing therapies aimed at preventing hematoma expansion are in progress, including aggressive blood pressure reduction, treatment with recombinant factor VIIa guided by CT angiography findings, and surgical intervention for superficial hematomas without intraventricular extension. Hematoma expansion is so far the only marker of outcome that is amenable to treatment and thus a potentially important therapeutic target. PMID:23466430

    Full Text Available Background: strokes are the third leading cause of death among adults and 10-15 % of them are due to spontaneous intracerebral hemorrhage. Objective: to characterize spontaneous intracerebral hemorrhage through computed tomography scan and its outcome. Methods: a case series study was conducted comprising patients diagnosed with spontaneous intracerebral hemorrhage admitted to the Arnaldo Milián Castro Provincial University Hospital in Villa Clara from January 2009 to January 2010. Tomographic variables of interest were derived from evaluation of spontaneous intracerebral hematomas. Results: fifty-nine cases of spontaneous intracerebral hemorrhage were studied, 23 were located in lobar regions, 4 had severe midline shift, and 2 showed volume greater than 80 ml. Eight out of eleven with extension into the ventricular system had an unfavorable outcome. Among those with thalamic hemorrhage, patients with diameter larger than 4cm and extension into the ventricular system died. Patients with putaminal hemorrhage larger than 4 cm and posterior fossa hematoma with hydrocephalus had a poor outcome, as well as most individuals (55 with other mass effects. Most lobar hematomas (14 out of 23 had a satisfactory outcome, unlike cerebellar and brainstem hematomas. Conclusions: tomographic variables that had a negative impact on the outcome were: volume greater than 80 ml, severe midline shift, diameter larger than 4 cm, extension into the ventricular system, hydrocephalus, other signs of mass effect and brainstem location.

    Full text: Purpose: Despite the latest advances in medical treatment and neuro critical care, patients suffering spontaneous intracerebral hemorrhage (SICH) still have a very poor prognosis, with a greater mortality and larger neurological deficits at the survivors than for ischemic stroke. Many authors have shown that there are many mechanisms involved in the pathology of SICH: edema, ischemia, inflammation, apoptosis. All of these factors are affecting brain tissue surrounding hematoma and are responsible of the progressive neurological deterioration; most of these damages are not revealed by anatomical imaging techniques. The aim of our study was to asses the role of brain perfusion SPECT in demonstrating perfusion changes in SICH patients. Method: 17 SICH pts were studied. All pts underwent same day CT and brain SPECT with 99mTcHMPAO, 24h-5d from onset of stroke. Results: 14/17 pts showed a larger perfusion defect than expected after CT. In 2 pts hematoma diameter was comparable on CT and SPECT; 1pt had quasinormal aspect of SPECT study. In pts with larger defects, SPECT revealed a large cold spot with similar size compared with CT, and a surrounding hypo perfused area. 6/17 pts revealed cortical hyper perfusion adjacent to hypo perfused area and corresponding to a normal-appearing brain tissue on CT. In 3 pts we found crossed cerebellar diaskisis.In 2 pts we found cortical hypo perfused area in the contralateral cortex, with normal appearing brain tissue on CT. Conclusions: Brain perfusion SPECT revealed different types of perfusion changes in the brain tissue surrounding hematoma. These areas contain viable brain tissue that may be a target for future ne uroprotective strategies. Further studies are definitely required to demonstrate prognostic significance of these changes, but we can conclude that brain perfusion SPECT can play an important role in SICH, by early demonstrating functional changes responsible of clinical deterioration, thus allowing prompt

    All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

    Preexisting cognitive impairment is a predictor of cognitive decline after ischemic stroke, but evidence in intracerebral hemorrhage (ICH) is limited. We aimed to determine the prevalence of premorbid cognitive impairment in patients with ICH. We included patients with acute ICH. Pre-ICH cognitive impairment was determined based on the results of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) that uses information from close relatives. Patients were assessed as having been cognitively impaired with an IQCODE score of ≥3.44; an IQCODE ≥4.00 indicated pre-ICH dementia. CT and MRI images were reviewed to determine the extent of white matter lesions and to measure the radial width of the temporal horn as marker of brain atrophy. We investigated differences of cardiovascular risk factors and imaging data between patients with and without pre-ICH cognitive impairment using correlation analyses, uni- and multivariable regression models. Functional neurological state was assessed using the modified Rankin Scale (mRS). The mRS was dichotomized at the level of 3, and a premorbid mRS of 0-2 was considered as functional independency. Among the 89 participants, median age was 70 years (interquartile range 58-78) and 52 (58.4%) were male. IQCODE indicated pre-ICH cognitive impairment in 18.0% (16 of 89), and 83.1% were functionally independent before ICH. Cognitive impairment was associated with a premorbid mRS≥3 (chi squared test, P=0.009). In multivariable analysis, prior stroke/transient ischemic attack (OR 18.29, 95%-CI 1.945-172.033, P=.011) and hematoma volume (OR 0.90, 95%-CI 0.812-0.991, P=.033) were independently associated with pre-ICH cognitive impairment. In conclusion, cognitive impairment frequently precedes ICH. A higher frequency of cerebrovascular events suggests a role of vascular processes in the development of cognitive impairment before ICH. © 2016 John Wiley & Sons A/S.

    A case of calcified subdural hematoma associated with hypertensive intracerebral hemorrhage is reported. A left frontal subdural hematoma with left putaminal hemorrhage was incidentally found when a CT scan was performed to evaluate right hemiparesis and aphasia in a 55-year-old man. The putaminal hemorrhage was not very extensive, but his clinical symptoms were rather serious. Not only the putaminal hemorrhage, but also the presence of the calcified subdural hematoma was considered to have caused his clinical deterioration. The subtotal removal of the calcified subdural hematoma brought about a good result. (author)

    The aim of this investigation was to determine the factors influencing acute intracerebral hemorrhage severity on admission and clinical outcomes at discharge. Sixty acute stroke hospitals throughout Japan participated in the Japan Standard Stroke Registry Study (JSSRS), documenting the in-hospital course of 16,630 consecutive patients with acute stroke from January 2001 to March 2004. We identified 2,840 adult patients from the JSSRS who had intracerebral hemorrhage. Intracerebral hemorrhage severity on admission was strongly related to age, previous stroke history, and hemorrhage size in a monotone fashion [chi(2)(9) = 374.5, p < 0.0001]. Drinking history was also predictive of intracerebral hemorrhage severity on admission, but the association was not monotone. Interestingly, intracerebral hemorrhage severity on admission was increased in nondrinking and heavy drinking compared to mild drinking (p < 0.05). Unsuccessful outcome (modified Rankin scale score = 3-6) was related to age, previous stroke history, hemorrhage size, and intracerebral hemorrhage severity on admission [chi(2)(9) = 830.4, p < 0.0001]. Mortality was related to hemorrhage size, intraventricular hemorrhage, intracerebral hemorrhage severity on admission, and surgical operation [chi(2)(7) = 540.4, p < 0.0001]. We could find four varied factors associated with intracerebral hemorrhage severity and its outcomes. Interestingly, intracerebral hemorrhage severity tended to be greater in nondrinking and heavy drinking than mild drinking. Additionally, surgical operation decreased intracerebral hemorrhage mortality. Copyright 2008 S. Karger AG, Basel.

    Five (9.6%) of 52 cases of supretentorial hypertensive intracerebral hemorrhage which suffered rehemorrhage in the contralateral regions were analyzed in the present study, and the 28 cases reported since 1950 were reviewed. The literature suggests that the time between the first hemorrhage and the second was quite long. However, the present series showed that re-hemorrhage in the contralateral side developed within one month in three out of five cases. In case 1, hemorrhages developed almost simultaneously in the left thalamus and in the right putamen. Three characteristics were observed: The symptoms including hemiparesis and/or hemispheric signs related to the first hemorrhage had a tendency to exacerbate after the second attack in other the contralateral region in the second attack, symptoms excessively severe for the size of the hematoma developed. Finally, the clinical course after the second hemorrhage was poor. (author)

    The clinical series consisted of 28 patients with hypertensive intracerebral hematoma observed in the natural course from 1976 through 1978. A total of 114 repeated computer tomographic (CT) examinations were made with an EMI-1010 or an ACTA-0100 scanner. The experimental series consisted of 26 adult mongrel dogs with intracerebral hematoma near the basal ganglia. In 20 dogs, autopsy and histological examinations were performed, and in 12 dogs a total of 31 repeated CT examinations were carried out with an EMI scanner (matrix 320 x 320, high-definition scan). In the clinical series, the time of the decrease in density beginning in the periphery of the hematoma, like the first appearance of ring enhancement and its concentric concentration toward the center of the hematoma, was not affected by the size of the hematoma. However, the time when the intracerebral hematoma was resolved did vary with the size of the hematoma. In the experimental series, the tissue reaction near the periphery of the intracerebral hematoma seemed to be a constant process. First, a necrotic layer appeared, and then this was replaced by immature connective tissue with granular cells, newly formed vessels, and reticulin fibers; finally, the immature layer was gradually transformed into mature connective tissue with collagenous fibers. Moreover, this process of change was not related to the size of the hematoma. The following correlations were suggested by a chronological observation of the CT images and the histological appearance: 1) acute stage - homogeneous high-density extending to the periphery, apperance of a necrotic layer; 2) subacute stage - decreased density spreading from the periphery and formation of ring enhancement, apperance of immature connective tissue with reticulin fibers; 3) chronic stage - concentric concentration of ring enhancement, mature connective tissue with collagenous fibers

    Among the stroke subtypes, intracerebral hemorrhage (ICH) has the worst prognosis and still lacks a specific treatment. The present manuscript contains the Brazilian guidelines for the management of ICH. It was elaborated by the executive committee of the Brazilian Cerebrovascular Diseases Society and was based on a broad review of articles about the theme. The text aims to provide a rational for the management of patients with an acute ICH, with the diagnostic and therapeutic resources that are available in Brazil.

    Several radiologic features such as hematoma volume are related to poor outcome following an intracerebral hemorrhage and can be measured with transcranial duplex sonography. We sought to determine the prognostic value of transcranial duplex sonography in patients with intracerebral hemorrhage. We conducted a prospective study of patients diagnosed with spontaneous intracerebral hemorrhage. Transcranial duplex sonography examinations were performed within 2 hours of baseline CT, and we recorded the following variables: hematoma volume, midline shift, third ventricle and lateral ventricle diameters, and the pulsatility index in both MCAs. We correlated these data with the CT scans and assessed the prognostic value of the transcranial duplex sonography measurements. We assessed early neurologic deterioration during hospitalization and mortality at 1-month follow-up. We included 35 patients with a mean age of 72.2 ± 12.8 years. Median baseline hematoma volume was 9.85 mL (interquartile range, 2.74-68.29 mL). We found good agreement and excellent correlation between transcranial duplex sonography and CT when measuring hematoma volume ( r = 0.791; P duplex sonography measurements showed that hematoma volume was an independent predictor of early neurologic deterioration (OR, 1.078; 95% CI, 1.023-1.135) and mortality (OR, 1.089; 95% CI, 1.020-1.160). A second regression analysis with CT variables also demonstrated that hematoma volume was associated with early neurologic deterioration and mortality. When we compared the rating operation curves of both models, their predictive power was similar. Transcranial duplex sonography showed an excellent correlation with CT in assessing hematoma volume and midline shift in patients with intracerebral hemorrhage. Hematoma volume measured with transcranial duplex sonography was an independent predictor of poor outcome. © 2017 by American Journal of Neuroradiology.

    Full Text Available Ventriculoperitoneal shunt is a routinely performed treatment in neurosurgical department. Intracerebral hemorrhage, as a complication after shunt catheterization, is really rare but with high mortality. In this study, we reported a case of a 74-year-old man who suffered from repeated intracerebral hemorrhage after ventriculoperitoneal shunt. The first hemorrhage happened 63 h after the 1st surgery, and most hematomas were located in the ipsilateral occipital lobe and intraventricles, along the ventricular catheter. Fresh blood clot casts blocked the external ventricular draining catheter, which was inserted into the right front horn during the 3rd surgery, indicating new intraventricular bleeding happened. A large hematoma in ipsilateral frontal lobe was detected on the 3rd day after the removal of external ventricular draining catheter. Different hemorrhagic locations and time points were encountered on the same case. We discussed the possible causes of repeated hemorrhage for this case, and the pre-operative preparation including risk evaluation in future clinical work.

    Polymorphonuclear neutrophils (PMNs) infiltration into brain parenchyma after cerebrovascular accidents is viewed as a key component of secondary brain injury. Interestingly, a recent study of ischemic stroke suggests that after ischemic stroke, PMNs do not enter brain parenchyma and as such may cause no harm to the brain. Thus, the present study was designed to determine PMNs' behavior after intracerebral hemorrhage (ICH). Using the autologous blood injection model of ICH in rats and immunohistochemistry for PMNs and vascular components, we evaluated the temporal and spatial PMNs distribution in the ICH-affected brain. We found that, similar to ischemia, there is a robust increase in presence of PMNs in the ICH-injured tissue that lasts for at least 1 to 2 weeks. However, in contrast to what was suggested for ischemia, besides PMNs that stay in association with the vasculature, after ICH, we found abundance of intraparenchymal PMNs (with no obvious association with vessels) in the ICH core and hematoma border, especially between 1 and 7 days after the ictus. Interestingly, the increased presence of intraparenchymal PMNs after ICH coincided with the massive loss of microvascular integrity, suggesting vascular disruption as a potential cause of PMNs presence in the brain parenchyma. Our study indicates that in contrast to ischemic stroke, after ICH, PMNs target not only vascular compartment but also brain parenchyma in the affected brain. As such, it is possible that the pathogenic role and therapeutic implications of targeting PMNs after ICH could be different from these after ischemic stroke. Our work suggests the needs for more studies addressing the role of PMNs in ICH.

  18. Cerebral blood flow in patients with hypertensive intracerebral hemorrhage

    Cerebral blood flow (CBF) is usually decreased in patients with hypertensive intracerebral hemorrhage. A total of 81 regional CBF measurements were performed using an Anger-type dynamic gamma camera with the Xe-133 intracarotid injection technique in 23 patients with thalamic hemorrhage, 18 with small putaminal hemorrhage, and 5 with large putaminal hemorrhage. The results were as follows: Bilateral CBF in thalamic hemorrhages was markedly reduced from 1 week to 2 or 3 weeks after onset; it then showed a tendency to increase from 4 weeks to 3 months. In putaminal hemorrhages, however, CBF in the affected hemisphere did not tend to increase despite increased CBF in the contralateral hemisphere. CBF of the affected hemisphere was plotted against the hematoma volume, and the biphasic curve showed an initial steep and subsequent gentle slope in both putaminal and thalamic hemorrhages. The degree of CBF reduction in the affected hemisphere was more evident in thalamic than in putaminal hemorrhages. However, the flow reduction in the contralateral hemisphere was more obvious in thalamic than in putaminal hemorrhages. Factors such as mean arterial blood pressure, partial pressure of arterial carbon dioxide, cerebrospinal fluid pressure, hematocrit and the degree of involvement of the internal capsule, as shown on CT scan were not directly related to CBF reduction. In conclusion, it is unlikely that the mass effect of the hematoma plays an important role in the discrepancy between CBF reduction in putaminal and thalamic hemorrhages. Rather, the discrepancy may result from the impairment of respective anatomical sites in the thalamic and putaminal regions. It is also suggested that ipsilateral as well as contralateral CBF reduction is probably caused by the decreased cortical metabolic demand. This may be based on the disruption of the transneural fiber pathways, which connect both the thalamus and putamen to the cerebral cortex. (author)

    Aging may be an important factor affecting brain injury by intracerebral hemorrhage (ICH). In the present study, we investigated the responses of glial cells and monocytes to intracerebral hemorrhage in normal and aged rats. ICH was induced by microinjecting autologous whole blood (15 microL) into the striatum of young (4 month old) and aged (24 month old) Sprague-Dawley rats. Age-dependent relations of brain tissue damage with glial and macrophageal responses were evaluated. Three days after ICH, activated microglia/macrophages with OX42-positive processes and swollen cytoplasm were more abundantly distributed around and inside the hemorrhagic lesions. These were more dramatic in aged versus the young rats. Western blot and immunohistochemistry analyses showed that the expression of interleukin-1beta protein after ICH was greater in aged rats, whereas the expression of GFAP and ciliary neurotrophic factor protein after ICH was significantly lower in aged rats. These results suggest that ICH causes more severe brain injury in aged rats most likely due to overactivation of microglia/macrophages and concomitant repression of reactive astrocytes.

    Magnetic resonance (MR) imaging as an indicator of recovery from hemiparesis was evaluated in 60 patients with spontaneous intracerebral hemorrhage. T{sub 2}-weighted MR images revealed early MR abnormality (EMA) of the corticospinal tract within 1 week of ictus. Most patients without EMA recovered beyond Brunnstrom's Recovery Stage 3 while only a few patients with EMA did so. Patients with EMA cannot regain motor function because EMA is almost always followed by complete tract degeneration. EMA in the brainstem and poor motor function recovery are closely correlated.

    Background and purpose Although unclear-onset ischemic stroke, including wake-up ischemic stroke, is drawing attention as a potential target for reperfusion therapy, acute unclear-onset intracerebral hemorrhage has been understudied. Clinical characteristics, hematoma features, and outcomes of patients who developed intracerebral hemorrhage during sleep or those with intracerebral hemorrhage who were unconscious when witnessed were determined. Methods Consecutive intracerebral hemorrhage patients admitted within 24 hours after onset or last-known normal time were classified into clear-onset intracerebral hemorrhage and unclear-onset intracerebral hemorrhage groups. Outcomes included initial hematoma volume, initial National Institutes of Health Stroke Scale score, hematoma growth on 24-hour follow-up computed tomography, and vital and functional prognoses at 30 days. Results Of 377 studied patients (122 women, 69 ± 11 years old), 147 (39.0%) had unclear-onset intracerebral hemorrhage. Patients with unclear-onset intracerebral hemorrhage had larger hematoma volumes (p = 0.044) and higher National Institutes of Health Stroke Scale scores (p Hematoma growth was similarly common between the two groups (p = 0.176). There were fewer patients with modified Rankin Scale (mRS) scores of 0-2 (p = 0.033) and more patients with mRS scores of 5-6 (p = 0.009) and with fatal outcomes (p = 0.049) in unclear-onset intracerebral hemorrhage group compared with clear-onset intracerebral hemorrhage as crude values, but not after adjustment. Conclusions Patients with unclear-onset intracerebral hemorrhage presented with larger hematomas and higher National Institutes of Health Stroke Scale scores at emergent visits than those with clear-onset intracerebral hemorrhage, independent of underlying characteristics. Unclear-onset intracerebral hemorrhage patients showed poorer 30-day vital and functional outcomes than clear-onset intracerebral hemorrhage patients

    Full Text Available The aim of the paper was to evaluate the surgical outcome in patients with spontaneous supratentorial intracerebral hemorrhage (ICH after surgical intervention, in respect to the initial clinical conditions, age, sex, hemispheric side and anatomic localization of ICH. Thirty-eight surgically treated patients with spontaneous supratentorial intracerebral hemorrhage were included in the study. The surgical outcome was evaluated three months after the initial admission, according to the Glasgow Outcome Scale (GOS. The surgical treatment was successful in 14 patients (37%, whereas it was unsuccessful in 24 patients (63%. We have detected a significant negative correlation between the Glasgow Coma Scale (GCS scores on admission and the GOS scores after three months, suggesting worse neurological outcome in patients with initially lower GCS scores. The surgical outcome in patients with ICH was not affected by the sex, the hemispheric side and the anatomic localization of ICH, but the age of the patients was estimated as a significant factor for their functional outcome, with younger patients being more likely to be treated successfully. The surgical outcome is affected from the initial clinical state of the patients and their age. The treatment of ICH is still an unsolved clinical problem and the development of new surgical techniques with larger efficiency in the evacuation of the hematoma is necessary, thus making a minimal damage to the normal brain tissue, as well as decreasing the possibility of postoperative bleeding.

    Delirium symptoms are associated with later worse functional outcomes and long-term cognitive impairments, but the neuroanatomical basis for delirium symptoms in patients with acute brain injury is currently uncertain. We tested the hypothesis that hematoma location is predictive of delirium symptoms in patients with intracerebral hemorrhage, a model disease where patients are typically not sedated or bacteremic. We prospectively identified 90 patients with intracerebral hemorrhage who underwent routine twice-daily screening for delirium symptoms with a validated examination. Voxel-based lesion-symptom mapping with acute computed tomography was used to identify hematoma locations associated with delirium symptoms (N = 89). Acute delirium symptoms were predicted by hematoma of right-hemisphere subcortical white matter (superior longitudinal fasciculus) and parahippocampal gyrus. Hematoma including these locations had an odds ratio for delirium of 13 (95 % CI 3.9-43.3, P delirium symptoms. Higher odds ratio for delirium was increased due to hematoma location. The location of neurological injury could be of high prognostic value for predicting delirium symptoms.

    Rationale Acute intracerebral hemorrhage inflicts a high-economic and -health burden. Computed tomography angiography spot sign is a predictor of hematoma expansion, is associated with poor clinical outcome and is an important stratifying variable for patients treated with haemostatic therapy. Aims We aim to compare the effect of treatment with tranexamic acid to placebo for the prevention of hemorrhage growth in patients with high-risk acute intracerebral hemorrhage with a positive spot sign. Design The tranexamic acid for acute intracerebral hemorrhage growth predicted by spot sign (TRAIGE) is a prospective, multicenter, placebo-controlled, double-blind, investigator-led, randomized clinical trial that will include an estimated 240 participants. Patients with intracerebral hemorrhage demonstrating symptom onset within 8 h and with the spot sign as a biomarker for ongoing hemorrhage, and no contraindications for antifibrinolytic therapy, will be enrolled to receive either tranexamic acid or placebo. The primary outcome measure is the presence of hemorrhage growth defined as an increase in intracerebral hemorrhage volume >33% or >6 ml from baseline to 24 ± 2 h. The secondary outcomes include safety and clinical outcomes. Conclusion The TRAIGE trial evaluates the efficacy of haemostatic therapy with tranexamic acid in the prevention of hemorrhage growth among high-risk patients with acute intracerebral hemorrhage.

  10. Spontaneous Intracerebral Hemorrhage Image Analysis Methods: A Survey

    Science.gov (United States)

    Pérez, Noel; Valdés, Jose; Guevara, Miguel; Silva, Augusto

    Spontaneous intracerebral hemorrhages (ICH) account for 10-30% of all strokes and are a result of acute bleeding into the brain due to ruptures of small penetrating arteries. Despite major advancements in the management of ischemic strokes and other causes of hemorrhagic strokes, such as ruptured aneurysm, arteriovenous malformations (AVMs), or cavernous angioma, during the past several decades, limited progress has been made in the treatment of ICH, and the prognosis for patients who suffer them remains poor. The societal impact of these hemorrhagic strokes is magnified by the fact that affected patients typically are a decade younger than those afflicted with ischemic strokes. The ICH continues to kill or disable most of their victims. Some studies show that those who suffer ICH have a 30-day mortality rate of 35-44% and a 6-month mortality rate approaching 50%. Approximately 700,000 new strokes occur in the United States annually and approximately 15% are hem-orrhagic strokes related to ICH. The poor outcome associated with ICH is related to the extent of brain damage. ICH produces direct destruction and compression of surrounding brain tissue. Direct compression causes poor perfusion and venous drainage to surrounding penumbra at risk, resulting in ischemia to the tissues that most need perfusion [16].

    We attempted to evaluate the diagnostic usefulness of the degree of perilesional edema around intracerebral hematoma in predicting the underlying cause. This study included 54 patients with intracerebral hematoma for whom the underlying cause was confirmed by biopsy, radiological or clinical methods. Cases of subarachnoid hemorrhage, hemorrhagic transformation of cerebral infarction and intraventricular hemorrhage were excluded. The lesion size was defined as the average value of the longest axis and the axis perpendicular to this. The size of the perilesional edema was defined as the longest width of the edema. In all cases, the sizes of the lesion and edema were measured on the T2 weighted image. We defined the edema ratio as the edema size divided by the lesion size. 23 cases were diagnosed as intracerebral hemorrhage due to neoplastic conditions, such as metastasis (n=17), glioblastoma (n=5), hemangioblastoma (n=1). 31 cases were caused by non-neoplastic conditions, such as spontaneous hypertensive hemorrhage (n=23), arteriovenous malformation (n=4), cavernous angioma (n=3), and moya-moya disease (n=1). In fourteen cases, which were confirmed as malignant intracerebral hemorrhage, the edema ratio was more than 100%. Of the other cases, only 8 were confirmed as malignant intracerebral hemorrhage. It was found that the larger the edema ratio, the more malignant the intracerebral hemorrhage, and this result was statistically significant (p<0.001). Measurement of perilesional edema and the intracerebral hematoma ratio may be useful in predicting the underlying causes

  12. Putative role of prostaglandin receptor in intracerebral hemorrhage

    Full Text Available Each year, approximately 795,000 people experience a new or recurrent stroke. Of all strokes, 84% are ischemic, 13% are intracerebral hemorrhage (ICH strokes and 3% are subarachnoid hemorrhage (SAH strokes. Despite the decreased incidence of ischemic stroke, there has been no change in the incidence of hemorrhagic stroke in the last decade. ICH is a devastating disease 37-38% of patients between the ages of 45-64 die within 30 days. In an effort to prevent ischemic and hemorrhagic strokes we and others have been studying the role of prostaglandins and their receptors. Prostaglandins are bioactive lipids derived from the metabolism of arachidonic acid. They sustain homeostatic functions and mediate pathogenic mechanisms, including the inflammatory response. Most prostaglandins are produced from specific enzymes and act upon cells via distinct G-protein coupled receptors. The presence of multiple prostaglandin receptor’s cross-reactivity and coupling to different signal transduction pathways allow differentiated cells to respond to prostaglandins in a unique manner. Due to the number of prostaglandin receptors, prostaglandin-dependent signaling can function either to promote neuronal survival or injury following acute excitotoxicity, hypoxia, and stress induced by ICH. To better understand the mechanisms of neuronal survival and neurotoxicity mediated by prostaglandin receptors, it is essential to understand downstream signaling. Several groups including ours have discovered unique roles for prostaglandin receptors in rodent models of ischemic stroke, excitotoxicity, and Alzheimer disease, highlighting the emerging role of prostaglandin receptor signaling in hemorrhagic stroke with a focus on cyclic-adenosine monophosphate (cAMP and calcium (Ca2+ signaling. We review current ICH data and discuss future directions notably on prostaglandin receptors, which may lead to the development of unique therapeutic targets against hemorrhagic stroke and

    Background and Purpose: Stroke symptoms are caused in 10 to 15% by intracerebral hemorrhage. From the clinical examination it is often impossible to differentiate intracerebralhemorrhage from cerebral ischemia. To exclude intracerebral hemorrhage as the cause of clinical symptoms a CT is usually performed. The aim of our study was a direct comparison of the sensitivity of Computed Tomography and MRI using different MR sequences for the detection of acute intracerebral hemorrhage. Methods: In 8 male Wistar rats intracerebral hemorrhage was induced by infusion of collagenase into the caudate nucleus. After 1 hour the brains were subsequently imaged with CT and MRI using T2- and T1-weighted Spin Echo sequences, diffusion-weighted sequences, T2*-weighted gradient echo sequences and FLAIR-sequences. Visibility of the intracerebral hemorrhage was examined using a scoring system for 1=not visible to 5=excellent visible. Finally, the intracerebral hemorrhage was verified by histological staining. Results: In all animals, intracerebral hemorrhage was visible in T2*-weighted gradient echo and diffusion weighted MR images 1 h after infusion of collagenase. T2- and PD-weighted SE images were positive in 7/8 rats. T1-weighted images revealed signal changes in 5/8 rats, and FLAIR sequence was positive in 8/8 rats. In CT intracerebral hemorrhage was only visible in 3/8 rats. When measuring the increase of Hounsfield units within the suspected hemisphere we saw a mean increase of 7% compared to the normal hemisphere in 3/8 rats. Conclusions: In this animal model, T2*-weighted magnetic resonance imaging proved to be the most sensitive imaging modality in the detection of acute intracerebral hemorrhage and is by far more sensitive than CT.

  15. Necrostatin-1 Reduces Neurovascular Injury after Intracerebral Hemorrhage

    2014-01-01

    Full Text Available Intracerebral hemorrhage (ICH is the most common form of hemorrhagic stroke, accounting for 15% of all strokes. ICH has the highest acute mortality and the worst long-term prognosis of all stroke subtypes. Unfortunately, the dearth of clinically effective treatment options makes ICH the least treatable form of stroke, emphasizing the need for novel therapeutic targets. Recent work by our laboratory identified a novel role for the necroptosis inhibitor, necrostatin-1, in limiting neurovascular injury in tissue culture models of hemorrhagic injury. In the present study, we tested the hypothesis that necrostatin-1 reduces neurovascular injury after collagenase-induced ICH in mice. Necrostatin-1 significantly reduced hematoma volume by 54% at 72 h after-ICH, as compared to either sham-injured mice or mice administered an inactive, structural analogue of necrostatin-1. Necrostatin-1 also limited cell death by 48%, reduced blood-brain barrier opening by 51%, attenuated edema development to sham levels, and improved neurobehavioral outcomes after ICH. These data suggest a potential clinical utility for necrostatin-1 and/or novel necroptosis inhibitors as an adjunct therapy to reduce neurological injury and improve patient outcomes after ICH.

    Although lacunar stroke (LS) and deep intracerebral hemorrhage (dICH) represent acute manifestations of the same pathological process involving cerebral small vessels (small vessel disease), it remains unclear what factors predispose to one phenotype rather than the other at individual level. Consecutive patients with either acute symptomatic LS or dICH were prospectively enrolled as part of a multicenter Italian study. We compared the risk factor profile of the 2 subgroups using multivariable logistic regression. During a time course of 9.5 years, 1931 subjects (1434 LS and 497 dICH; mean age, 71.3±13.3 years; males, 55.5%) qualified for the analysis. Current smoking was associated with LS (odds ratio [OR], 2.17; Prisk factor profile of dICH differs from that associated with LS. This might be used for disease risk stratification at individual level. © 2016 American Heart Association, Inc.

    inhibitors was not related to statistically significantly improved clinical outcome. CONCLUSIONS: Approximately 1 of 2 patients surviving intracerebral hemorrhage had a high risk of thromboembolism. Postdischarge use of oral anticoagulation therapy was associated with a lower risk of all-cause mortality......BACKGROUND AND PURPOSE: The effectiveness and safety of antithrombotic therapy (AT) among patients with a history of intracerebral hemorrhage remain uncertain. We therefore determined the prevalence of indication for AT among patients hospitalized with first-time intracerebral hemorrhage...... and examined the impact of subsequent AT use on the long-term clinical outcome. METHODS: We performed a population-based cohort study using nationwide Danish medical registries. Patients with risk of thromboembolism surviving the first 30 days after hospitalization because of intracerebral hemorrhage were...

    Objectives This cross-sectional survey explored the characteristics and outcomes of direct oral anticoagulant (DOAC)–associated nontraumatic intracerebral hemorrhages (ICHs) by analyzing a large nationwide Japanese discharge database. Methods We analyzed data from 2,245 patients who experienced ICHs while taking anticoagulants (DOAC: 227; warfarin: 2,018) and were urgently hospitalized at 621 institutions in Japan between April 2010 and March 2015. We compared the DOAC- and warfarin-treated patients based on their backgrounds, ICH severities, antiplatelet therapies at admission, hematoma removal surgeries, reversal agents, mortality rates, and modified Rankin Scale scores at discharge. Results DOAC-associated ICHs were less likely to cause moderately or severely impaired consciousness (DOAC-associated ICHs: 31.3%; warfarin-associated ICHs: 39.4%; p = 0.002) or require surgical removal (DOAC-associated ICHs: 5.3%; warfarin-associated ICHs: 9.9%; p = 0.024) in the univariate analysis. Propensity score analysis revealed that patients with DOAC-associated ICHs also exhibited lower mortality rates within 1 day (odds ratio [OR] 4.96, p = 0.005), within 7 days (OR 2.29, p = 0.037), and during hospitalization (OR 1.96, p = 0.039). Conclusions This nationwide study revealed that DOAC-treated patients had less severe ICHs and lower mortality rates than did warfarin-treated patients, probably due to milder hemorrhages at admission and lower hematoma expansion frequencies.

    Intracerebral hemorrhage is a common cause of acute neurological deterioration and a frequent indication for emergency neuroimaging. Stroke symptoms are caused in 10 to 15% by intracerebral hemorrhage. It is often not possible to differentiate intracerebral hemorrhage from cerebral ischemia by clinical examination. The therapeutic decision between thrombolysis or conservative therapy is comprised by the etiology. To exclude intracerebral hemorrhage as the cause of clinical symptoms, a CT is usually performed. Localisation and extension of the acute intracerebral hemorrhage are easy to detect. Subacute and chronic intracerebral hemorrhage are better delineated with magnetic resonance imaging. The different signal of the hemorrhage can be used for the age of the intracerebral hemorrhage. The cause of a non-traumatic intracerebral hemorrhage is in over 60% hypertony, less frequent alcoholism, malformation, or amyloid angiopathy. Uncommon causes of hemorrhage are head trauma, blood dyscrasia, tumor or venous thrombosis. Non-traumatic intracerebral hemorrhage are most common in patients between 50 and 70 years. In younger patients a malformation should be excluded with a cerebral angiography. Intracerebral hemorrhages are usually conservatively treated, in some cases an operative decompression is performed. (orig.) [German] Die intrazerebrale Blutung ist eine haeufige Ursache akut auftretender neurologischer Symptome und fuehrt oft zu einer notfallmaessigen neuroradiologischen Untersuchung. Etwa 15% der 'Schlaganfaelle' sind auf eine intrazerebrale Blutung zurueckzufuehren. Intrazerebrale Blutungen sind klinisch oft nicht von ischaemischen Infarkten zu unterscheiden. Eine Computertomographie ist zur Zeit fuer die Diagnosesicherung - und damit auch zur weiterfuehrenden Therapie - unerlaesslich. Ausdehnung und Lokalisation der akuten intrazerebralen Blutung koennen damit schnell und sicher erfasst werden. Subakute und chronische Blutungen sind dagegen

    The Full Outline of Unresponsiveness (FOUR) Score is a validated scale describing the essentials of a coma examination, including motor response, eye opening and eye movements, brainstem reflexes, and respiratory pattern. We incorporated the FOUR Score into the existing ICH Score and evaluated its accuracy of risk assessment in spontaneous intracerebral hemorrhage (ICH). Consecutive patients admitted to our institution from 2009 to 2012 with spontaneous ICH were reviewed. The ICH Score was calculated using patient age, hemorrhage location, hemorrhage volume, evidence of intraventricular extension, and Glasgow Coma Scale (GCS). The FOUR Score was then incorporated into the ICH Score as a substitute for the GCS (ICH Score FS ). The ability of the 2 scores to predict mortality at 1 month was then compared. In total, 274 patients met the inclusion criteria. The median age was 73 years (interquartile range 60-82) and 138 (50.4%) were male. Overall mortality at 1 month was 28.8% (n = 79). The area under the receiver operating characteristic curve was .91 for the ICH Score and .89 for the ICH Score FS . For ICH Scores of 1, 2, 3, 4, and 5, 1-month mortality was 4.2%, 29.9%, 62.5%, 95.0%, and 100%. In the ICH Score FS model, mortality was 10.7%, 26.5%, 64.5%, 88.9%, and 100% for scores of 1, 2, 3, 4, and 5, respectively. The ICH Score and the ICH Score FS predict 1-month mortality with comparable accuracy. As the FOUR Score provides additional clinical information regarding patient status, it may be a reasonable substitute for the GCS into the ICH Score. Copyright © 2018 National Stroke Association.

    Neuropeptide Y (NPY) is one of the most potent endogenous vasoconstrictors, and its contribution to the multifactorial cascade of cerebral vasospasm due to nontraumatic subarachnoid hemorrhage (SAH) is not yet fully understood. This experimental study compared the hemorrhage-specific course of NPY secretion into cerebrospinal fluid (CSF) and into plasma between 2 groups: patients with SAH and patients with basal ganglia hemorrhage (BGH) or cerebellar hemorrhage (CH) over the first 10 days after hemorrhage. Seventy-nine patients were prospectively included: SAH patients (n=66) (historic population) and intracerebral hemorrhage patients (n=13). All patients received an external ventricular drain within 24 hours of the onset of bleeding. CSF and plasma were drawn daily from day 1 to day 10. The levels of NPY were determined by means of competitive enzyme immunoassay. The CSF samples of 29 patients (historic population) who had undergone spinal anesthesia due to orthopedic surgery served as the control group. NPY levels in CSF were significantly higher in the 2 hemorrhage groups than in the control group. However, the 2 hemorrhage groups showed significant differences in NPY levels in CSF (SAH mean, 0.842 ng/mL vs. BGH/CH mean, 0.250 ng/mL; P<0.001) as well as in the course of NPY secretion into CSF over the 10-day period. NPY levels in plasma did not differ significantly among SAH, BGH/CH, and controls. Our findings support the hypothesis that excessive release of NPY into CSF but not into plasma is specific to aneurysmal SAH in the acute period of 10 days after hemorrhage. In BGH/CH, CSF levels of NPY were also increased, but the range was much lower.

    Although diabetes mellitus is an established independent risk factor for ischemic stroke, the association between fasting blood glucose and intracerebral hemorrhage (ICH) is limited and inconsistent. The objective of the current study was to examine the potential impact of long-term fasting blood glucose concentration on subsequent risk of ICH. This prospective study included 96 110 participants of the Kailuan study, living in Kailuan community, Tangshan city, China, who were free of cardiovascular diseases and cancer at baseline (2006). Fasting blood glucose concentration was measured in 2006, 2008, 2010, and 2012. Updated cumulative average fasting blood glucose concentration was used as primary exposure of the current study. Incident ICH from 2006 to 2015 was confirmed by review of medical records. During 817 531 person-years of follow-up, we identified 755 incident ICH cases. The nadir risk of ICH was observed at fasting blood glucose concentration of 5.3 mmol/L. The adjusted hazard ratios and their 95% confidence intervals (CIs) of ICH were 1.59 (95% CI, 1.26-2.02) for diabetes mellitus or fasting blood glucose ≥7.00 mmol/L, 1.31 (95% CI, 1.02-1.69) for impaired fasting blood glucose (fasting blood glucose, 6.10-6.99 mmol/L), 0.98 (95% CI, 0.78-1.22) for fasting blood glucose 5.60 to 6.09 mmol/L, and 2.04 (95% CI, 1.23-3.38) for hypoglycemia (fasting blood glucose, fasting blood glucose 4.00 to 5.59 mmol/L. The results persisted after excluding individuals who used hypoglycemic, aspirin, antihypertensive agents, or anticoagulants, and those with intracerebral hemorrhagic cases occurred in the first 2 years of follow-up. In this large community-based cohort, low (fasting blood glucose concentrations were associated with higher risk of incident ICH, relative to fasting blood glucose concentrations of 4.00 to 6.09 mmol/L. © 2017 American Heart Association, Inc.

    Regional cerebral blood flow (rCBF) was measured in 36 patients with hypertensive intracerebral hemorrhage (putaminal hemorrhage) treated surgically, using the Xenon-133 intracarotid injection method. The correlations between CBF in four regions, (the hemisphere, the frontal region, the sensori-motor area and the focal area) and the duration from the operation, the conscious level, the hematoma volume and motor function were investigated. Mean cerebral blood flow (MCBF), rCBF in sensori-motor area and in the focal area showed a value below 30 ml/100g/min. for any duration after the operation within one year. However, in the frontal region rCBF tends to increase from 4 months after the operation. There was a close correlation between the conscious level and CBF, especially in the frontal region. The higher CBF was noted in the better consciousness group. In hematoma cases the larger the hematoma volume (especially those over 31 ml)the lower the CBF in all three regions. In the focal area rCBF showed the lowest value among these three regions and was dependent on the hematoma volume, while frontal region revealed the highest flow value of them all, even in cases with a hematoma volume over 81 ml. There was a significant difference in rCBF between cases with severe motor disturbance and cases with moderate motor disturbance, except in the focal area. In the frontal region rCBF coincides rather well to the degree of motor disturbance. While, rCBF in the focal area was less than 30 ml/100g/min., and showed no correlation to motor function.

    This cross-sectional survey explored the characteristics and outcomes of direct oral anticoagulant (DOAC)-associated nontraumatic intracerebral hemorrhages (ICHs) by analyzing a large nationwide Japanese discharge database. We analyzed data from 2,245 patients who experienced ICHs while taking anticoagulants (DOAC: 227; warfarin: 2,018) and were urgently hospitalized at 621 institutions in Japan between April 2010 and March 2015. We compared the DOAC- and warfarin-treated patients based on their backgrounds, ICH severities, antiplatelet therapies at admission, hematoma removal surgeries, reversal agents, mortality rates, and modified Rankin Scale scores at discharge. DOAC-associated ICHs were less likely to cause moderately or severely impaired consciousness (DOAC-associated ICHs: 31.3%; warfarin-associated ICHs: 39.4%; p = 0.002) or require surgical removal (DOAC-associated ICHs: 5.3%; warfarin-associated ICHs: 9.9%; p = 0.024) in the univariate analysis. Propensity score analysis revealed that patients with DOAC-associated ICHs also exhibited lower mortality rates within 1 day (odds ratio [OR] 4.96, p = 0.005), within 7 days (OR 2.29, p = 0.037), and during hospitalization (OR 1.96, p = 0.039). This nationwide study revealed that DOAC-treated patients had less severe ICHs and lower mortality rates than did warfarin-treated patients, probably due to milder hemorrhages at admission and lower hematoma expansion frequencies.

    Full Text Available Stroke is very common in patients with sleep disordered breathing, especially in the elderly. We report the case of a 26-year-old man who had been referred to us with a sudden left side motor weakness of the body, headache, chronic fatigue, and witnessed sleep apneas. Intracerebral hemorrhage in the right external capsule and putamen was identified upon brain computed tomography. He had hypertension which had not been diagnosed previously. On polysomnography, apnea-hypopnea index was 73.0/h and arousal index was 74.7/h, indicating severe sleep apnea. Continuous positive airway pressure titration was conducted to determine the optimal pressure to alleviate the respiratory disturbances. Treatment with antihypertensive medication reduced blood pressure (BP from 197/145 mm Hg to 130/80 mm Hg after 10 days of use. Co-treatment with the medication and auto-adjustable positive airway pressure additionally decreased BP to 110/60 mm Hg and normalized respiratory disturbances. In addition to BP, left hemiparesis, morning headache, daytime sleepiness, and chronic fatigue were all improved. Early treatment of OSA could help facilitate the rehabilitation of or recovery of weakness in such patients.

    Full Text Available BACKGROUND: Spontaneous intracerebral hemorrhage (ICH represents about 15% of all strokes and is associated with high mortality rates. Our aim was to identify the gene expression changes and biological pathways altered in the brain following ICH. METHODOLOGY/PRINCIPAL FINDINGS: Twelve brain samples were obtained from four deceased patients who suffered an ICH including perihematomal tissue (PH and the corresponding contralateral white (CW and grey (CG matter. Affymetrix GeneChip platform for analysis of over 47,000 transcripts was conducted. Microarray Analysis Suite 5.0 was used to process array images and the Ingenuity Pathway Analysis System was used to analyze biological mechanisms and functions of the genes. We identified 468 genes in the PH areas displaying a different expression pattern with a fold change between -3.74 and +5.16 when compared to the contralateral areas (291 overexpressed and 177 underexpressed. The top genes which appeared most significantly overexpressed in the PH areas codify for cytokines, chemokines, coagulation factors, cell growth and proliferation factors while the underexpressed codify for proteins involved in cell cycle or neurotrophins. Validation and replication studies at gene and protein level in brain samples confirmed microarray results. CONCLUSIONS: The genomic responses identified in this study provide valuable information about potential biomarkers and target molecules altered in the perihematomal regions.

    Intracerebral hemorrhage (ICH) is the most severe form of stroke, but data on readmission after ICH are sparse. We aimed to determine frequency, causes, and predictors of 30-day readmission after ICH. This retrospective cohort study includes all spontaneous ICH survivors admitted to the stroke unit at Haukeland University Hospital in Bergen in Norway from July 2007 to December 2013. Patients were followed by review of electronic medical charts, and the first unplanned readmission within 30 days after discharge was used as final outcome. Cox regression analysis was performed to identify predictors of 30-day readmission. We identified 226 patients with spontaneous ICH, 70 (31.0%) of whom died before discharge or were discharged to palliative care. Of the remaining 156 ICH survivors, 28 (18.0%) were readmitted within 30 days. Median time to readmission was 12 days (IQR 4.5 - 18.5). Most patients were readmitted due to infections ( N  = 13). None of the patients were readmitted with recurrent stroke. Pneumonia and enteral feeding during the index hospitalization were associated with readmission for infections (both p  readmission (HR 1.06, 95% CI 1.02 - 1.11, p  =   .006). Almost one in five of our spontaneous ICH survivors was readmitted within 30 days, and most readmissions were caused by infections.

    Erythrolysis occurs in the clot after intracerebral hemorrhage (ICH) and the release of hemoglobin causes brain injury but it is unclear when such lysis occurs. The present study examined early erythrolysis in rats. ICH rats had an intra-caudate injection of 100 µl autologous blood and sham rats had a needle insertion. All rats had T2 and T2* MRI scanning and brains were used for histology and CD163 (a hemoglobin scavenger receptor) and DARPP-32 (a neuronal marker) immunohistochemistry. There was marked heterogeneity within the hematoma on T2* MRI, with a hyper- or isointense core and a hypointense periphery. Hematoxylin and eosin staining in the same animals showed significant erythrolysis in the core with the formation of erythrocyte ghosts. The degree of erythrolysis correlated with the severity of perihematomal neuronal loss. Perihematomal CD163 was increased by day 1 after ICH and may be involved in clearing hemoglobin caused by early hemolysis. Furthermore, ICH resulted in more severe erythrolysis, neuronal loss and perihematomal CD163 upregulation in spontaneously hypertensive rats compared to Wistar Kyoto rats. In conclusions, T2*MRI detectable early erythrolysis occurred in the clot after ICH, and activated CD163. Hypertension is associated with enhanced erythrolysis in the hematoma. PMID:27783383

    Background: Mortality and morbidity associated with intracerebral hemorrhage is still high. Up to now, there are no evidence-based effective treatments for acute ICH. This study is to assess the effect of tranexamic acid (TXA) on hematoma growth of patients with spontaneous ICH compared to a placebo. Methods: We performed a single-blinded, randomised placebo-controlled trial of TXA (intravenous 1g bolus, followed by infusion TXA 1 g/hour for 8 hours) in acute (< 8 hours) primary ICH. Strict blood pressure control (target SBP 140-160 mmHg). A repeat Computed Tomography brain was done after 24 hours to reassess hematoma growth. The primary objective is to test the effect of TXA on hematoma growth. Other objective was to test the feasibility, tolerability, and adverse events of TXA in primary ICH. Results: Statistical analysis showed significant hematoma growth in control group after 24 hours compared to baseline (14.3300 vs 17.9940, P = 0.001) whereas the treatment group there is no significant hematoma size expansion between baseline and after 24 hours (P = 0.313). Conclusions: This study showed a significant hematoma volume expansion in the control group compared to the treatment group. PMID:27006639

    Spontaneous intracerebral hemorrhage (ICH) is one type of the most devastating cerebrovascular diseases worldwide, which causes high morbidity and mortality. However, efficient treatment is still lacking. Stem cell therapy has shown good neuroprotective and neurorestorative effect in ICH and is a promising treatment. In this study, our aim was to review the therapeutic effects, strategies, related mechanisms and safety issues of various types of stem cell for ICH treatment. Numerous studies had demonstrated the therapeutic effects of diverse stem cell types in ICH. The potential mechanisms include tissue repair and replacement, neurotrophy, promotion of neurogenesis and angiogenesis, anti-apoptosis, immunoregulation and anti-inflammation and so forth. The microenvironment of the central nervous system (CNS) can also influence the effects of stem cell therapy. The detailed therapeutic strategies for ICH treatment such as cell type, the number of cells, time window, and the routes of medication delivery, varied greatly among different studies and had not been determined. Moreover, the safety issues of stem cell therapy for ICH should not be ignored. Stem cell therapy showed good therapeutic effect in ICH, making it a promising treatment. However, safety should be carefully evaluated, and more clinical trials are required before stem cell therapy can be extensively applied to clinical use.

    We present a novel robotic approach for the rapid, minimally invasive treatment of Intracerebral Hemorrhage (ICH), in which a hematoma or blood clot arises in the brain parenchyma. We present a custom image-guided robot system that delivers a steerable cannula into the lesion and aspirates it from the inside. The steerable cannula consists of an initial straight tube delivered in a manner similar to image-guided biopsy (and which uses a commercial image guidance system), followed by the sequential deployment of multiple individual precurved elastic tubes. Rather than deploying the tubes simultaneously, as has been done in nearly all prior studies, we deploy the tubes one at a time, using a compilation of their individual workspaces to reach desired points inside the lesion. This represents a new paradigm in active cannula research, defining a novel procedure-planning problem. A design that solves this problem can potentially save many lives by enabling brain decompression both more rapidly and less invasively than is possible through the traditional open surgery approach. Experimental results include a comparison of the simulated and actual workspaces of the prototype robot, and an accuracy evaluation of the system.

    Recent evidence suggests that a potential harmful relationship exists between cannabis use and ischemic stroke. The purpose of this study was to determine the implications of cannabis use in intracerebral hemorrhage (ICH) patients. An analysis of an international, multicenter, observational database of consecutive patients with spontaneous ICH was conducted. We extracted the following characteristics on presentation: demographics, risk factors, antiplatelet or anticoagulant use, Glasgow Coma Scale, ICH score, neuroimaging parameters, and urine toxicology screen (UTS) results. Modified Rankin Scale (mRS) score was utilized for determination of outcome at discharge. Adjusted logistic ordinal regression was used as shift analysis to assess the impact of cannabis use on mRS score at discharge. The adjusted common OR measured the likelihood that cannabis use would lead to lower mRS scores. Within a cohort of 725 spontaneous ICH patients, UTS was positive for cannabinoids in 8.6%. Cannabinoids-positive (CB+) patients were more frequently Caucasian (p cannabis use was discovered in nearly 10% of patients with spontaneous ICH. Although there was no relationship between cannabis use and specific ICH characteristics, CB+ patients had milder ICH presentation and less disability at discharge. © 2016 S. Karger AG, Basel.

    Churg-Strauss syndrome (CSS) is a systemic necrotizing vasculitis of the small and medium vessels, associated with extravascular eosinophilic granulomas, peripheral eosinophilia, and asthma. The exact etiology of CSS is unknown. This syndrome commonly affects the lungs, peripheral nerves, skin, heart, and gastrointestinal tract, but rarely the central nervous system. Subarachnoid and intracerebral hemorrhage in CSS patients is extremely rare; however, clinicians should consider that CSS may be a cause of intracranial hemorrhage and its high rate of mortality and morbidity. The authors report on two cases of subarachnoid and intracerebral hemorrhage with CSS and discuss a brief review of CSS. PMID:23210058

    Positron emission tomography (PET) now provides the capability of measuring regional cerebral blood flow with high resolution and little risk. In this study, we utilized PET in six premature infants (920 to 1,200 g) with major intraventricular hemorrhage and hemorrhagic intracerebral involvement to measure regional cerebral blood flow during the acute period (5 to 17 days of age). Cerebral blood flow was determined after intravenous injection of H 2 O, labeled with the positron-emitting isotope, 15 O. Findings were similar and dramatic in all six infants. In the area of hemorrhagic intracerebral involvement, little or no cerebral blood flow was detected. However, in addition, surprisingly, a marked two- to fourfold reduction in cerebral blood flow was observed throughout the affected hemisphere, well posterior and lateral to the intracerebral hematoma, including cerebral white matter and, to a lesser extent, frontal, temporal, and parietal cortex. In the one infant studied a second time, ie, at 3 months of age, the extent and severity of the decreased cerebral blood flows in the affected hemisphere were similar to those observed on the study during the neonatal period. At the three autopsies, the affected left hemisphere showed extensive infarction, corroborating the PET scans. These observations, the first demonstration of the use of PET in the determination of regional cerebral blood flow in the newborn, show marked impairments in regional cerebral blood flow in the hemisphere containing an apparently restricted intracerebral hematoma, indicating that the hemorrhagic intracerebral involvement is only a component of a much larger lesion, ischemic in basic nature, ie, an infarction. This large ischemic lesion explains the poor neurologic outcome in infants with intraventricular hemorrhage and hemorrhagic intracerebral involvement

    Previous study revealed the value of dexamethasone in the treatment of vasogenic edema associated with brain tumor and abscess. However there are poor documented studies about its usefulness in primary intracerebral hemorrhage. In this study we evaluated dexamethasone effects in primary intracerebral hemorrhage. In a double blind randomized placebo-controlled clinical trial we evaluated 200 intracerebral hemorrhage cases between 40 to 80 years old whom were admitted at Golestan Hospital (Ahwaz, IR) between March 2002 and March 2003. They were divided in two groups dexamethasone (N=100) and placebo (N=100). Then mortality, GI bleeding, fever, electrolytes disturbances, hypertension and hyperglycemic status were analyzed in two groups. Ethical considerations were employed and subjects were followed by appropriate statistical methods for 21 days to assess the major outcomes. Mortality was much higher in the dexamethasone group; Dexamethasone group (49.3%) and placebo (23.4%) and also fever was higher seen in the dexamethasone group; dexamethasone group (40.2%) and placebo group (24.7%) but there was not any significant statistical difference between two groups as regards other complications. Dexamethasone is widely used for cerebral edema associated conditions but in this study we saw that it's complications in intracerebral hemorrhage such as increasing fever and mortality are significantly higher. Hence it use for treatment of primary intracerebral hemorrhage should be reconsidered. (author)

    To investigate the effects of intensive blood pressure (BP) lowering according to baseline BP levels and optimal achieved BP levels in patients with acute intracerebral hemorrhage (ICH). INTERACT2 was an open, blinded endpoint, randomized controlled trial in 2,839 patients with ICH within 6 hours of onset and elevated systolic BP (SBP) (150-220 mm Hg) who were allocated to receive intensive (target SBP <140 mm Hg within 1 hour, with lower limit of 130 mm Hg for treatment cessation) or guideline-recommended (target SBP <180 mm Hg) BP-lowering treatment. Outcome was physical function across all 7 levels of the modified Rankin Scale at 90 days. Analysis of the randomized comparisons showed that intensive BP lowering produced comparable benefits on physical function at 90 days in 5 subgroups defined by baseline SBP of <160, 160-169, 170-179, 180-189, and ≥190 mm Hg (p homogeneity = 0.790). Analyses of achieved BP showed linear increases in the risk of physical dysfunction for achieved SBP above 130 mm Hg for both hyperacute (1-24 hours) and acute (2-7 days) phases while modest increases were also observed for achieved SBP below 130 mm Hg. Intensive BP lowering appears beneficial across a wide range of baseline SBP levels, and target SBP level of 130-139 mm Hg is likely to provide maximum benefit in acute ICH. This study provides Class I evidence that the effect of intensive BP lowering on physical function is not influenced by baseline BP. © 2014 American Academy of Neurology.

    We tested the hypothesis that admission serum magnesium levels are associated with hematoma volume, hematoma growth, and functional outcomes in patients with intracerebral hemorrhage (ICH). Patients presenting with spontaneous ICH were enrolled in an observational cohort study that prospectively collected demographic, clinical, laboratory, radiographic, and outcome data. We performed univariate and adjusted multivariate analyses to assess for associations between serum magnesium levels and initial hematoma volume, final hematoma volume, and in-hospital hematoma growth as radiographic measures of hemostasis, and functional outcome measured by the modified Rankin Scale (mRS) at 3 months. We included 290 patients for analysis. Admission serum magnesium was 2.0 ± 0.3 mg/dL. Lower admission magnesium levels were associated with larger initial hematoma volumes on univariate ( p = 0.02), parsimoniously adjusted ( p = 0.002), and fully adjusted models ( p = 0.006), as well as greater hematoma growth ( p = 0.004, p = 0.005, and p = 0.008, respectively) and larger final hematoma volumes ( p = 0.02, p = 0.001, and p = 0.002, respectively). Lower admission magnesium level was associated with worse functional outcomes at 3 months (i.e., higher mRS; odds ratio 0.14, 95% confidence interval 0.03-0.64, p = 0.011) after adjustment for age, admission Glasgow Coma Scale score, initial hematoma volume, time from symptom onset to initial CT, and hematoma growth, with evidence that the effect of magnesium is mediated through hematoma growth. These data support the hypothesis that magnesium exerts a clinically meaningful influence on hemostasis in patients with ICH. © 2017 American Academy of Neurology.

    Concomitant acute ischemic lesions are detected in up to a quarter of patients with spontaneous intracerebral hemorrhage (ICH). Influence of bleeding pattern and intraventricular hemorrhage (IVH) on risk of ischemic lesions has not been investigated. Retrospective study of all 500 patients enrolled in the CLEAR III randomized controlled trial of thrombolytic removal of obstructive IVH using external ventricular drainage. The primary outcome measure was radiologically confirmed ischemic lesions, as reported by the Safety Event Committee and confirmed by two neurologists. We assessed predictors of ischemic lesions including analysis of bleeding patterns (ICH, IVH and subarachnoid hemorrhage) on computed tomography scans (CT). Secondary outcomes were blinded assessment of mortality and modified Rankin scale (mRS) at 30 and 180 days. Ischemic lesions occurred in 23 (4.6%) during first 30 days after ICH. Independent risk factors associated with ischemic lesions in logistic regression models adjusted for confounders were higher IVH volume (p = 0.004) and persistent subarachnoid hemorrhage on CT scan (p = 0.03). Patients with initial IVH volume ≥ 15 ml had five times the odds of concomitant ischemic lesions compared to IVH volume < 15 ml. Patients with ischemic lesions had significantly higher odds of death at 1 and 6 months (but not poor outcome; mRS 4-6) compared to patients without concurrent ischemic lesions. Occurrence of ischemic lesions in the acute phase of IVH is not uncommon and is significantly associated with increased early and late mortality. Extra-parenchymal blood (larger IVH and visible subarachnoid hemorrhage) is a strong predictor for development of concomitant ischemic lesions after ICH.

    Full Text Available Clinical outcomes are positively associated with hematoma absorption. The monocyte-macrophage scavenger receptor, CD163, plays an important role in the metabolism of hemoglobin, and a soluble form of CD163 is present in plasma and other tissue fluids; therefore, we speculated that serum CD163 affects hematoma absorption after intracerebral hemorrhage. Patients with intracerebral hemorrhage were divided into high- and low-level groups according to the average CD163 level (1,977.79 ± 832.91 ng/mL. Compared with the high-level group, the low-level group had a significantly slower hematoma absorption rate, and significantly increased National Institutes of Health Stroke Scale scores and modified Rankin Scale scores. These results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.

    The key step for minimally invasive intracerebral hemorrhage surgery is precisely positioning the hematoma location in the brain before and during the hematoma surgery, which can significantly improves the success rate of puncture hematoma. We designed a 3D computerized surgical plan (CSP) workstation precisely to locate brain hematoma based on Multi-Planar Reconstruction (MPR) visualization technique. We used ten patients' CT/MR studies to verify our designed CSP intracerebral hemorrhage localization method. With the doctor's assessment and comparing with the results of manual measurements, the output of CSP WS for hematoma surgery is more precise and reliable than manual procedure.

    Full Text Available Cognitive impairment seems to be frequent in intracerebral hemorrhage (ICH survivors, but remains widely understudied. In this study, we investigated the frequency and patterns of vascular cognitive disorders (VCDs in patients with cerebral amyloid angiopathy (CAA-related and deep ICH compared to patients with mild cognitive impairment due to Alzheimer's disease (MCI-AD and healthy controls.We prospectively recruited 20 patients with CAA-related lobar ICH, 20 with deep ICH, 20 with MCI-AD and 17 healthy controls. Patients with cognitive decline pre-ICH were excluded from the analysis. Each participant underwent a comprehensive neuropsychological assessment and a structural brain MRI. Cognitive assessment was performed at a median delay of 4 months after the acute phase in ICH patients, and more than 6 months after the first complaint in MCI-AD patients. Cognitive profiles were compared between groups. The prevalence of VCDs in the ICH groups was estimated using the recent VASCOG criteria."Mild" and "major VCDs" were respectively observed in 87.5% and 2.5% of all ICH patients. Every patient in the CAA group had mild VCDs. No significant difference was observed in cognitive functioning between CAA-related and deep ICH patients. The most impaired process in the CAA group was naming, with a mean (±standard deviation z-score of -5.2 ±5.5, followed by processing speed (-4.1±3.3, executive functioning (-2.6 ±2.5, memory (-2.4 ±3.5 and attention (-0.9 ±1.3. This cognitive pattern was different from the MCI-AD patients, but the groups were only different in gestural praxis, and by construction, in memory processes.VCDs are frequent after ICH. Cognitive patterns of patients with deep or CAA-related ICH did not differ, but there was impaired performance in specific domains distinct from the effects of Alzheimer's disease.URL: http://www.clinicaltrials.gov.

    Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

    Intracerebral hemorrhage (ICH) is a common type of fatal stroke, accounting for about 15% to 20% of all strokes. Hemorrhagic strokes are associated with high mortality and morbidity, and increasing evidence shows that innate immune responses and inflammatory injury play a critical role in ICH-induced neurological deficits. However, the signaling pathways involved in ICH-induced inflammatory responses remain elusive. Toll-like receptor 4 (TLR4) belongs to a large family of pattern recognition ...

    Early hematoma growth is a devastating neurological complication after intracerebral hemorrhage. We aim to report and evaluate the usefulness of computed tomography (CT) black hole sign in predicting hematoma growth in patients with intracerebral hemorrhage. Patients with intracerebral hemorrhage were screened for the presence of CT black hole sign on admission head CT performed within 6 hours after onset of symptoms. The black hole sign was defined as hypoattenuatting area encapsulated within the hyperattenuating hematoma with a clearly defined border. The sensitivity, specificity, and positive and negative predictive values of CT black hole sign in predicting hematoma expansion were calculated. Logistic regression analyses were used to assess the presence of the black hole sign and early hematoma growth. A total of 206 patients were enrolled. Black hole sign was found in 30 (14.6%) of 206 patients on the baseline CT scan. The black hole sign was more common in patients with hematoma growth (31.9%) than those without hematoma growth (5.8%; Phole sign in predicting early hematoma growth were 31.9%, 94.1%, 73.3%, and 73.2%, respectively. The time-to-admission CT scan, baseline hematoma volume, and the presence of black hole sign on admission CT independently predict hematoma growth in multivariate model. The CT black hole sign could be used as a simple and easy-to-use predictor for early hematoma growth in patients with intracerebral hemorrhage. © 2016 American Heart Association, Inc.

    Full Text Available Objective To investigate whether cerebral microbleeds (CMBs can predict hematoma growth in elderly patients with acute hypertensive intracerebral hemorrhage.  Methods The clinical records of 98 elderly patients with acute hypertensive intracerebral hemorrhage who underwent initial CT within 6 h and repeated CT and susceptibility-weighted imaging (SWI within 24 h of onset were analyzed. Based on the performance of SWI, patients were divided into microbleeds group and non-microbleeds group. Forward multivariate Logistic regression analysis was used to evaluate the predicting value of CMBs on the growth of intracerebral hematoma.  Results Among 98 patients, hematoma growth was found in 25 cases in the second CT scan. The ratio in microbleeds group was significantly higher than that in non-microbleeds group (43.75% vs 16.67%; χ2 = 8.319, P = 0.004. Multivariate Logistic regression showed that CMBs was independent risk factor for intracerebral hematoma (OR = 0.241, 95%CI: 0.065-0.861; P = 0.017.  Conclusions CMBs in patients with acute intracerebral hematoma can predict high risk of hemotoma growth, and effective treatment should be taken to improve the prognosis of patients. DOI: 10.3969/j.issn.1672-6731.2015.01.012

    The value of neurosurgical interventions after spontaneous intracerebral hemorrhage (SICH) is uncertain. We evaluated clinical outcomes in patients diagnosed with SICH within 3 hours of symptom onset who underwent hematoma evacuation or external ventricular drainage (EVD) of the hematoma in the Factor Seven for Acute Hemorrhagic Stroke Trial (FAST). FAST was a randomized, multicenter, double-blind, placebo-controlled trial conducted between May 2005 and February 2007 at 122 sites in 22 countries. Neurosurgical procedures (hematoma evacuation and external ventricular drainage) performed at any point after hospital admission were prospectively recorded. Clinical outcomes evaluated were post-SICH disability, as assessed by the modified Rankin Scale; neurologic impairment, as assessed by the National Institutes of Health Stroke Scale; and mortality at 90 days after SICH onset. The impact of neurosurgical procedures on clinical outcomes was evaluated using multivariate logistic regression analysis, controlling for relevant baseline characteristics. Fifty-five of 821 patients underwent neurosurgery. Patients who underwent hematoma evacuation or EVD were on average younger, had greater baseline neurologic impairment, and lower levels of consciousness compared with patients who did not undergo neurosurgery. After adjusting for these differences and other relevant baseline characteristics, we found that neurosurgery was generally associated with unfavorable outcomes at day 90. Among the patients who underwent hematoma evacuation, those with lobar ICH had less ICH expansion than those with deep gray matter ICH, and the smaller expansion was associated with lower mortality. ICH volume was substantially decreased in patients who underwent hematoma evacuation between 24 and 72 hours after hospital admission, and this was associated with better clinical outcome. In conclusion, a small number of patients who underwent neurosurgery in FAST exhibited no overall clinical benefit

    Full Text Available Unpredicted sudden death arising from hemangiopericytoma with massive intracranial hemorrhage is quite rare. We encountered a patient with recurrent infratentorial hemangiopericytoma presenting as life-threatening massive intracerebral hemorrhage. A 43-year-old man who had undergone craniotomy for total resection of an infratentorial hemangiopericytoma 17 months earlier presented with morning headache and generalized convulsions. Computed tomography revealed a massive hematoma in the right infratentorial region causing tonsillar herniation and emergency surgery was performed to evacuate the hematoma. Histological findings revealed hemangiopericytoma with hemorrhage. Neurological status remained unimproved and brain death was confirmed postoperatively. Hemangiopericytoma presenting as massive hemorrhage is quite rare. Since the risk of life-threatening massive hemorrhage should be considered, careful postoperative long-term follow-up is very important to identify tumor recurrences, particularly in the posterior cranial fossa, even if the tumor is completely removed.

    In computed tomographic imaging of acute intracerebral hemorrhage spot sign on computed tomographic angiography has been established as a marker for hematoma expansion and poor clinical outcome. Although, magnetic resonance imaging (MRI) can accurately visualize acute intracerebral hemorrhage, a corresponding MRI marker is lacking to date. We prospectively examined 50 consecutive patients with acute intracerebral hemorrhage within 24 hours of symptom onset. The MRI protocol consisted of a standard stroke protocol and dynamic contrast-enhanced T1-weighted imaging with a time resolution of 7.07 s/batch. Stroke scores were assessed at admission and at time of discharge. Volume measurements of hematoma size and spot sign were performed with MRIcron. Contrast extravasation within sites of the hemorrhage (MRI spot sign) was seen in 46% of the patients. Patients with an MRI spot sign had a significantly shorter time to imaging than those without (Pspot sign compared with those without (P≤0.001). Hematoma expansion was observed in the spot sign group compared with the nonspot sign group, although the differences were not significant. Spot sign can be detected using MRI on postcontrast T1-weighted and dynamic T1-weighted images. It is associated with worse clinical outcome. The time course of contrast extravasation in dynamic T1 images indicates that these spots represent ongoing bleeding. © 2015 American Heart Association, Inc.

    The CT examination sometimes fail to localize the cerebral hemorrhage part depending on the seriousness and may embarrass the pathologist if he/she is not trained enough for emergencies. Therefore, an assisting role is necessary for examination, automatic and quick detection of the cerebral hemorrhage part, and supply of the quantitative information in emergencies. the computer based automatic detection and recognition system may be of a great service to the bleeding part detection. As a result of this research, we succeeded not only in automatic detection of the cerebral hemorrhage part by grafting threshold value handling, morphological operation, and roundness calculation onto the bleeding part but also in development of the PCA based classifier to screen any wrong choice in the detection candidate group. We think if we apply the new developed system to the cerebral hemorrhage patient in his critical condition, it will be very valuable data to the medical team for operation planning

    A 59-year-old woman was admitted to the hospital on November 6, 1983, after she suddenly lost consciousness. She was semicomatous, and the level of consciousness was evaluated as 100 according to the Japan Coma Scale. There were left hemiparesis and conjugate deviation to the right. CT scans obtained one hour after onset demonstrated bilateral intracerebral hemorrhages involving the right basal ganglia and the left posterior temporal region. Carotid angiograms failed to demonstrate the presence of either cerebral aneurysms or arteriovenous malformations which might be responsible for the intracerebral hemorrhages. A right fronto-temporal craniotomy was performed, and about 50 ml of intracerebral blood clots were evacuated by the transcortical approach. The patient was discharged with left hemiparesis, disorientation, and pseudobulbar palsy. A 57-year-old man was transferred to the hospital on February 22, 1986, with an episode of cerebral stroke. On admission he was free of symptoms except for mild hemiparesis on the right side. CT scan was performed nine days after onset, revealing bilateral intracerebral hemorrhages involving the right putamen and the left thalamus. Bilateral carotid angiograms showed an avascular mass lesion medial to the left insula, displacing both the left lenticulostriate arteries and the insular segment of the left middle cerebral artery laterally. No abnormal vascular lesions, such as cerebral aneurysms and arteriovenous malformations, were demonstrated. SPECT was performed using the continuous inhalation of Xe-133, and a prolonged decrease in the cerebral blood flow was demonstrated in the vicinity of the bilateral intracerebral hematomas, in contrast to the gradual alleviations shown on CT images.

    Full Text Available Despite improvements in management and prevention of intracerebral hemorrhage (ICH, there has been little improvement in mortality over the last 30 years. Hematoma expansion, primarily during the first few hours is highly predictive of neurological deterioration, poor functional outcome and mortality. For each 10% increase in ICH size, there is a 5% increase in mortality and an additional 16% chance of poorer functional outcome. As such, both the identification and prevention of hematoma expansion are attractive therapeutic targets in ICH. Previous studies suggest that contrast extravasation seen on CT Angiography (CTA, MRI, and digital subtraction angiography correlates with hematoma growth, indicating ongoing bleeding. Contrast extravasation on the arterial phase of a CTA has been coined the CTA Spot Sign. These easily identifiable foci of contrast enhancement have been identified as independent predictors of hematoma growth, mortality and clinical outcome in primary ICH. The Spot Sign score, developed to stratify risk of hematoma expansion, has shown high inter-observer agreement. Post-contrast leakage or delayed CTA Spot Sign, on post contrast CT following CTA or delayed CTA respectively are seen in an additional ~8% of patients and explain apparently false negative observations on early CTA imaging in patients subsequently undergoing hematoma expansion. CT perfusion provides an opportunity to acquire dynamic imaging and has been shown to quantify rates of contrast extravasation. Intravenous recombinant factor VIIa(rFVIIa within 4 hours of ICH onset has been shown to significantly reduce hematoma growth. However, clinical efficacy has yet to be proven. There is compelling evidence that cerebral amyloid angiopathy (CAA may precede the radiographic evidence of vascular disease and as such contribute to microbleeding. The interplay between microbleeding, CAA,CTA Spot Sign and genetic composition (ApoE genotype may be crucial in developing a

    Full Text Available Background and Study Object We report an unusual case of a benign lateral sphenoid wing meningioma that presented with, and was masked by, an acute intracerebral hemorrhage. Case Report A 68-year-old woman was admitted after sudden onset of coma. Computed tomography (CT revealed an intracerebral hemorrhage, without any underlying vascular pathology on CT angiography. During the surgery, we found a lateral sphenoid wing meningioma with intratumoral bleeding that extended into the surrounding brain parenchyma. Results We removed the hematoma and resected the tumor completely in the same session. The histopathological classification of the tumor was a WHO grade I meningothelial meningioma. The patient recovered very well after surgery, without significant neurological sequelae. Conclusions Having reviewed the relevant references from the medical literature, we consider this event as an extremely rare presentation of a benign sphenoid wing meningioma in a patient without any predisposing medical factors. The possible mechanisms of bleeding from this tumor type are discussed.

    Promoting hematoma absorption is a novel therapeutic strategy for intracerebral hemorrhage (ICH); however, the mechanism of hematoma absorption is unclear. The present study explored the function and potential mechanism of CD36 in hematoma absorption using in vitro and in vivo ICH models. Hematoma absorption in CD36-deficient ICH patients was examined. Compared with patients with normal CD36 expression, CD36-deficient ICH patients had slower hematoma adsorption and aggravated neurologic defic...

    We have recently proposed that retinoic acid receptor (NR1B) is a promising target of neuroprotective therapy for intracerebral hemorrhage, since pretreatment of mice with an NR1B1/NR1B2 agonist Am80 attenuated various pathological and neurological abnormalities associated with the disease. In the present study we further addressed the effects of retinoids as potential therapeutic drugs, using a collagenase-induced model of intracerebral hemorrhage. Daily oral administration of all-trans retinoic acid (ATRA; 5 and 15 mg/kg), a naturally occurring NR1B agonist, from 1 day before collagenase injection significantly inhibited loss of neurons within the hematoma. ATRA in the same treatment regimen also decreased the number of activated microglia/macrophages around the hematoma but did not affect the hematoma volume. ATRA (15 mg/kg) as well as Am80 (5mg/kg) rescued neurons in the central region of hematoma, even when drug administration was started from 6h after induction of intracerebral hemorrhage. However, in this post-treatment regimen, only Am80 significantly decreased the number of activated microglia/macrophages. With regard to neurological deficits, both ATRA (15 mg/kg) and Am80 (5mg/kg) given in the post-treatment regimen improved performance of mice in the beam-walking test and the modified limb-placing test. ATRA and Am80 also significantly attenuated damage of axon tracts as revealed by amyloid precursor protein immunohistochemistry. These results underscore potential therapeutic values of NR1B agonists for intracerebral hemorrhage. Copyright © 2012 Elsevier B.V. All rights reserved.

    Intracerebral hemorrhage (ICH) accounts for ∼ 10 to 15% of all strokes and is one of the major causes of stroke-related death and disability. After the initial hemorrhage, further bleeding and edema contribute to secondary damage and worsened outcomes. As such, goals of previous and ongoing trials are to prevent continued bleeding, as well as mitigate the impact of cerebral edema. Although no trials have shown a definite functional outcome benefit with a given intervention, much progress has been made recently. This review focuses on recent developments that inform the acute management of ICH. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Ventriculoperitoneal shunt (VPS) is a common procedure in daily neurosurgical practice. According to some reports, the rate of intracerebral hemorrhage secondary to VPS in patients with no bleeding tendency can be 43.1%; however, symptomatic intracerebral hemorrhage (SICH) secondary to VPS is rare with only sporadic cases reported in adults. To further elucidate the characteristics, mechanism, management, and prognosis of SICH secondary to VPS, we performed a retrospective study in our institution and a systematic review of the literature. A retrospective review of the medical records of patients admitted for VPS was performed. We also performed a systematic PubMed search of published studies. Of 5 patients identified at our institution, 3 experienced a favorable recovery. Including our case series, there were 16 (8 female) patients. The time interval from the termination of VPS procedure to SICH was 4 hours to 15 days. All but 1 patient experienced intracerebral hemorrhage adjacent to cannulation. Of 11 patients in whom a Glasgow Outcome Scale score could be obtained, the score was 5 in 4 patients, 4 in 1 patient, 3 in 1 patient, and 1 in 5 patients. SICH is a rare complication after VPS in adults without bleeding tendency. The mechanism is obscure, management is challenging, and prognosis is dismal. Future prospective study is anticipated.

  7. Predictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Hematoma expansion (HE occurs in approximately one-third of patients with intracerebral hemorrhage and leads to high rates of mortality and morbidity. Currently, contrast extravasation within hematoma, termed the spot sign on computed tomography angiography (CTA, has been identified as a strong independent predictor of early hematoma expansion. Past studies indicate that the spot sign is a dynamic entity and is indicative of active hemorrhage. Furthermore, to enhance the spot sign’s accuracy of predicting HE, spot parameters observed on CTA or dynamic CTA were used for its quantification. In addition, spot signs detected on multiphase CTA and dynamic CTA are shown to have higher sensitivity and specificity when compared with simple standardized spot sign detection in recent studies. Based on the spot sign, novel methods such as leakage sign and rate of contrast extravasation were explored to redefine HE prediction in combination with clinical characteristics and spot sign on CTA to assist clinical judgment. The spot sign is an accepted independent predictor of active hemorrhage and is used in both secondary intracerebral hemorrhage and the process of surgical assessment for hemorrhagic risk in patients with ischemic stroke. Spot sign predicts patients at high risk for hematoma expansion.

    Fifteen cases of early cerebral infarction and 14 cases of cerebral hemorrhage underwent diffusion weighted echo planar imaging. Increased intensity area was detected only 2 in 5 cases less than 3 hours from ictus, whereas infarction was correctly diagnosed in all cases over 3 hours. Infarcted area was increased on the follow-up study in 2 cases. Hematoma showed mixed intensity in hyper acute phase, very hypo in acute, mixed in subacute and very hyper in the chronic stage. High intensity area surrounded the hematoma. (author)

    This study aimed to evaluate the prognostic efficacy of magnetic resonance diffusion tensor fractional anisotropy (FA) for patients with hemiparesis due to intracerebral hemorrhage. Diffusion tensor FA brain images were acquired 14-21 days after putaminal and/or thalamic hemorrhage. The ratio of FA values within the cerebral peduncles of the affected and unaffected hemispheres (rFA) was calculated for each patient (n = 40) and assessed for correlation with Brunnstrom stage (BRS, 1-6), motor component of the functional independence measure (FIM-motor, 13-91), and the total length of stay (LOS) until discharge from rehabilitation (P hemiparesis due to putaminal and/or thalamic hemorrhage, particularly hand function recovery.

    1990-01-01

    Seventeen patients with intracerebral hemorrhage lesions were examined with magnetic resonance imaging at both 2.0 T and 0.5 T, in order to evaluate the capability of detecting and characterizing the hemorrhagic lesions at each field strength and to compare the signal intensities of the hemorrhages between both field strengths. The intervals between two imagings were within 2 hours in all patients except for 4 patients with subacute hematoma and occult cerebrovascular malformations in whom the intervals were 1 to 4 days. At each field strength, both T1 and T2-weighted spin echo(SE) images were obtained in all patients. All the hemorrhagic lesions were readily detected and characterized as hemorrhagic lesions at 2.0 T, whereas one lesion of chronic hemorrhage was not detected, and three lesions(one acute hemorrhage, one chronic hemorrhage and one occult cerebrovascular malformation) could not be characterized as hemorrhagic lesions at 0.5 T. There were statistically significant differences in signal intensity of the hematomas between 2.0 T and 0.5 T on proton density-weighted and T2-weighted images in cases of acute intracerebral hematomas: the hematomas seen as low intensity at 2.0 T appeared iso-or slightly high at 0.5 T. In conclusion, the intracerebral hematomas may be difficult to detect and to characterize with SE technique at 0.5 T, and then the gradient echo technique may be useful at 0.5 T

    A survey on stroke was conducted to evaluate the incidence of intracerebral hemorrhage and the prevalence of risk factors. The subjects, comprising those patients who suffesed a stroke, were registered on the Northern Hokkaido Stroke Study between July 2002 and June 2006. The severity of their illness was rated by the National Institutes of Health Stroke Scale (NIHSS) at hospital admission, while their outcome was determined by the mortality within 3 months and the mRS (modified Rankin Scale score). Of the 1,046 registered stroke patients, 271 (25.9%) were found to suffer from cerebral hemorrhage. Their mean age was 70.3±11.7 years; male-to-female ratio, 154/117; mean NIHSS at admission, 11.8±8.1; mortality within 3 months, 19.2%; and percentage who regained independence within 3 months (mRS: ≤2), 32.5%. A history of hypertension was found in 72.6%, and 13.7% had no treatment. MRI (T2*) revealed micro-hemorrhage outside the lesions in 67.5%. Forty-seven patients (17.3%) were taking anti-platelet agents at the onset of intracerebral hemorrhage. There was no significant difference between the mortalities of the anti-platelet-agent-users and non-users but the percentage of those regaining independence within 3 months was 19.1% for the users against 37.3% for the non-users (p=0.0177), with a significantly poor outcome in the user group. In northern Hokkaido, the incidence of cerebral hemorrhage remains high, and the percentage of those with poorly controlled or uncontrolled hypertension was 30%. These findings suggest a need to educate not only the inhabitants themselves but also the physicians engaged in their care. (author)

    Full Text Available Intracerebral hemorrhage (ICH remains a prevalent and severe cause of death and disability worldwide. Control of the hypertensive response in acute ICH has been a mainstay of ICH management, yet the optimal approaches and the yield of recommended strategies have been difficult to establish despite a large body of literature. Over the years, theoretical and observed risks and benefits of intensive blood pressure reduction in ICH have been studied in the form of animal models, radiographic studies, and two recent large, randomized patient trials. In this article, we review the historical and developing data and discuss remaining questions surrounding blood pressure management in acute ICH.

    Intracerebral hemorrhage (ICH) is a common and often fatal stroke subtype for which specific therapies and treatments remain elusive. To address this, many recent experimental and translational studies of ICH have been conducted, and these have led to several ongoing clinical trials. This review focuses on the progress of translational studies of ICH including those of the underlying causes and natural history of ICH, animal models of the condition, and effects of ICH on the immune and cardiac systems, among others. Current and potential clinical trials also are discussed for both ICH alone and with intraventricular extension. PMID:24139872

    It has been well documented that Momordica charantia polysaccharide (MCP) has multiple biological effects such as immune enhancement, anti-oxidation and anti-cancer. However, the potential protective effects of MCP on stroke damage and its relative mechanisms remain unclear. Our present study demonstrated that MCP could scavenge reactive oxygen species (ROS) in intra-cerebral hemorrhage damage, significantly attenuating the neuronal death induced by thrombin in primary hippocampal neurons. Furthermore, we found that MCP prevented the activation of the c-Jun N-terminal protein kinase (JNK3), c-Jun and caspase-3, which was caused by the intra-cerebral hemorrhage injury. Taken together, our study demonstrated that MCP had a neuroprotective effect in response to intra-cerebral hemorrhage and its mechanisms involved the inhibition of JNK3 signaling pathway.

    2016-01-01

    Full Text Available Stroke is the second leading cause of mortality worldwide, causing millions of deaths annually, and is also a major cause of disability-adjusted life years. Hemorrhagic stroke accounts for approximately 10 to 27% of all cases and has a fatality rate of about 50% in the first 30 days, with limited treatment possibilities. In the past two decades, the therapeutic potential of bone marrow-derived cells (particularly mesenchymal stem cells and mononuclear cells has been intensively investigated in preclinical models of different neurological diseases, including models of intracerebral hemorrhage and subarachnoid hemorrhage. More recently, clinical studies, most of them small, unblinded, and nonrandomized, have suggested that the therapy with bone marrow-derived cells is safe and feasible in patients with ischemic or hemorrhagic stroke. This review discusses the available evidence on the use of bone marrow-derived cells to treat hemorrhagic strokes. Distinctive properties of animal studies are analyzed, including study design, cell dose, administration route, therapeutic time window, and possible mechanisms of action. Furthermore, clinical trials are also reviewed and discussed, with the objective of improving future studies in the field.

    Acute hypertensive response is elevation of systolic blood pressure (SBP) in the first 24 h after symptom onset which is highly prevalent in patients with intracerebral hemorrhage (ICH). Observational studies suggested association between acute hypertensive response and hematoma expansion, peri-hematoma edema and death and disability, and possible reduction in these adverse outcomes with treatment of acute hypertensive response. Recent clinical trials have focused on determining the clinical efficacy of early intensive SBP reduction in ICH patients. The Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH-2) trial was the latest phase 3 randomized controlled multicenter clinical trial aimed to study the efficacy of early intensive reduction of SBP in ICH patients. In this review article, we summarize the results of recent clinical trials, treatment principles based on the latest guidelines, and the anticipated interpretation and incorporation of ATACH-2 trial results in clinical practice.

  17. The Injury and Therapy of Reactive Oxygen Species in Intracerebral Hemorrhage Looking at Mitochondria

    Directory of Open Access Journals (Sweden)

    Jie Qu

    2016-01-01

    Full Text Available Intracerebral hemorrhage is an emerging major health problem often resulting in death or disability. Reactive oxygen species (ROS have been identified as one of the major damaging factors in ischemic stroke. However, there is less discussion about ROS in hemorrhage stroke. Metabolic products of hemoglobin, excitatory amino acids, and inflammatory cells are all sources of ROS, and ROS harm the central nervous system through cell death and structural damage, especially disruption of the blood-brain barrier. We have considered the antioxidant system of the CNS itself and the drugs aiming to decrease ROS after ICH, and we find that mitochondria are key players in all of these aspects. Moreover, when the mitochondrial permeability transition pore opens, ROS-induced ROS release, which leads to extensive liberation of ROS and mitochondrial failure, occurs. Therefore, the mitochondrion may be a significant target for elucidating the problem of ROS in ICH; however, additional experimental support is required.

    Edaravone is widely used for treating ischemic stroke, but it is not still confirmed in intracerebral hemorrhage (ICH) as an ideal medication targeting the brain parenchyma. We aimed to investigate the neuroprotective effects of stereotactic administration of edaravone (SI) into the brain parenchyma. Intracerebral hemorrhage rat models were established by infusion of collagenase into the caudate nucleus. Neural functional recovery was assessed using modified neurological severity scores (mNSS). A comparative study of therapeutic effects between SI and intraperitoneal injection of edaravone (IP) involved in cerebral edema, blood-brain barrier (BBB) permeability, hematoma absorption, inflammatory response and neuronal apoptosis. Compared with IP, the mNSS was significantly (P < 0.05) improved by SI; cerebral edema and BBB permeability were dramatically ameliorated (P < 0.05); IL-4 and IL-10 levels increased, but IL-1β and TNF-α levels significantly decreased; neuron apoptosis decreased markedly (P < 0.05); and caspase-3 and Bax expression significantly dropped, but Bcl-2 increased in SI group (P < 0.05). SI markedly improved neurological deficits in ICH rat models via antiinflammatory and antiapoptosis mechanisms and promoted M2-type microglia differentiation. SI was effective in rats with collagenase-induced ICH. © 2016 The Authors. CNS Neuroscience & Therapeutics Published by John Wiley & Sons Ltd.

    Higher plasma 8-iso-Prostaglandin F2α concentrations have been associated with poor outcome of severe traumatic brain injury. We further investigated the relationships between plasma 8-iso-Prostaglandin F2α concentrations and clinical outcomes in patients with acute intracerebral hemorrhage. Plasma 8-iso-Prostaglandin F2α concentrations of 128 consecutive patients and 128 sex- and gender-matched healthy subjects were measured by enzyme-linked immunosorbent assay. We assessed their relationships with disease severity and clinical outcomes including 1-week mortality, 6-month mortality and unfavorable outcome (modified Rankin Scale score>2). Plasma 8-iso-Prostaglandin F2α concentrations were substantially higher in patients than in healthy controls. Plasma 8-iso-Prostaglandin F2α concentrations were positively associated with National Institutes of Health Stroke Scale (NIHSS) scores and hematoma volume using a multivariate linear regression. It emerged as an independent predictor for clinical outcomes of patients using a forward stepwise logistic regression. ROC curves identified the predictive values of plasma 8-iso-Prostaglandin F2α concentrations, and found its predictive value was similar to NIHSS scores and hematoma volumes. However, it just numerically added the predictive values of NIHSS score and hematoma volume. Increased plasma 8-iso-Prostaglandin F2α concentrations are associated with disease severity and clinical outcome after acute intracerebral hemorrhage. Copyright © 2014 Elsevier B.V.

    2016-07-01

    Full Text Available As current efforts have limited effects on the clinical outcome of intracerebral hemorrhage (ICH, the mechanisms including microglia/macrophages that involved inflammation need further investigation. Here, 0.4 units of collagenase VII were injected into the left caudate putamen (CPu to duplicate ICH rat models. In the brains of ICH rats, microglia/macrophages, the nearest cells to the hemorrhagic center, were observed as ameboid and Prussian-blue positive. Furthermore, the ameboid microglia/macrophages were differentiation (CD 68 and interleukin-1β (IL-1β positive, and neither CD206 nor chitinase3-like 3 (Ym1 positive, suggesting their strong abilities of phagocytosis and secretion of IL-1β. According to the distance to the hemorrhagic center, we selected four areas—I, II, III, and IV—to analyze the morphology of microglia/macrophages. The processes decreased successively from region I to region IV. Microglia/macrophages in region IV had no processes. The processes in region I were radially distributed, however, they showed obvious directivity towards the hemorrhagic center in regions II and III. Region III had the largest density of compactly arrayed microglia/macrophages. All these in vivo results present the high morphologic plasticity of microglia/macrophages and their functions in the pathogenesis of ICHs.

    The intracerebral hemorrhage (ICH) score is the most commonly used grading scale for stratifying functional outcome in patients with acute ICH. We sought to determine whether a combination of the ICH score and the computed tomographic angiography spot sign may improve outcome prediction in the cohort of a prospective multicenter hemorrhage trial. Prospectively collected data from 241 patients from the observational PREDICT study (Prediction of Hematoma Growth and Outcome in Patients With Intracerebral Hemorrhage Using the CT-Angiography Spot Sign) were analyzed. Functional outcome at 3 months was dichotomized using the modified Rankin Scale (0-3 versus 4-6). Performance of (1) the ICH score and (2) the spot sign ICH score-a scoring scale combining ICH score and spot sign number-was tested. Multivariable analysis demonstrated that ICH score (odds ratio, 3.2; 95% confidence interval, 2.2-4.8) and spot sign number (n=1: odds ratio, 2.7; 95% confidence interval, 1.1-7.4; n>1: odds ratio, 3.8; 95% confidence interval, 1.2-17.1) were independently predictive of functional outcome at 3 months with similar odds ratios. Prediction of functional outcome was not significantly different using the spot sign ICH score compared with the ICH score alone (spot sign ICH score area under curve versus ICH score area under curve: P =0.14). In the PREDICT cohort, a prognostic score adding the computed tomographic angiography-based spot sign to the established ICH score did not improve functional outcome prediction compared with the ICH score. © 2018 American Heart Association, Inc.

    Tenascin-C is a matricellular protein related to brain injury. We studied serum tenascin-C in acute intracerebral hemorrhage (ICH) and examined the associations with severity and outcome following the acute event. Tenascin-C samples were obtained from 162 patients with acute hemorrhagic stroke and 162 healthy controls. Poor 90-day functional outcome was defined as modified Rankin Scale score > 2. Early neurological deterioration (END) and hematoma growth (HG) were recorded at 24 h. Patients had higher tenascin-C levels than controls. Tenascin-C levels were positively correlated with hematoma volume or National Institutes of Health Stroke Scale score at baseline. Elevated tenascin-C levels were independently associated with END, HG, 90-day mortality and poor functional outcome. Moreover, tenascin-C levels significantly predicted END, HG and 90-day outcomes under receiver operating characteristic curves. An increase in serum tenascin-C level is associated with an adverse outcome in ICH patients, supporting the potential role of serum tenascin-C as a prognostic biomarker for hemorrhagic stroke.

    Due of paucity of studies on stress ulcer prophylaxis in intracerebral hemorrhage (ICH), we have evaluated the usefulness of ranitidine and sucralfate in preventing gastric hemorrhage (GH) in patients with ICH. In a hospital-based randomized placebo-controlled study, patients with CT-proven ICH within 7 days of ictus were randomized into ranitidine 50 mg i.v. eight hourly, sucralfate 1 g six hourly and placebo groups. Patients were conservatively managed. Primary endpoint was occurrence of GH within 15 days of ictus and secondary endpoint 1-month mortality. The mean age of the patients was 57.2 (range 25-90) years and 40 were females. There were 45 patients in ranitidine, 49 in sucralfate and 47 in placebo group. Demographic, clinical and radiological features were not significantly different in 3 groups. GH occurred in 11 (23.4%) patients in placebo, 5 (11.1%) in ranitidine and 7 (14.3%) in sucralfate group, which was not significant. Only one female had GH. There were 13 (27.7%) deaths in placebo, 5 (11.1%) in ranitidine and 12 (24.5%) in sucralfate group. Pneumonia occurred in placebo group in 5 (10.6%), ranitidine in 2 (4.4%) and sucralfate in 5 (10.2%) patients, which was not significantly different. Ranitidine and sucralfate do not seem to significantly prevent GH or reduce 1-month mortality.

    Sneddon's syndrome is characterized by livedo reticularis and multiple ischemic infarcts often associated with antiphospholipid antibodies. Intracerebral hemorrhage (ICH) is unusual in Sneddon's syndrome and has not been reported as the presenting complaint. We report a 38-year-old woman with a history of two miscarriages, Raynaud's phenomenon and livedo reticularis who presented acutely with ICH. Angiography showed prominent leptomeningeal and transdural anastomoses (pseudoangiomatosis). Anticardiolipin antibodies were positive. A right frontal brain biopsy failed to reveal vasculitis and a skin biopsy was nonspecific. MRI showed residual intracerebral hemorrhage (ICH), diffuse atrophy, multiple small white matter infarcts and leptomeningeal enhancement. This is the first report of Sneddon's syndrome presenting with an ICH. It shares features with the Divry-van Bogaert syndrome. We discuss the cause of the pseudoangiomatosis pattern and its role in the genesis of the hemorrhage and suggest that cerebral angiography should be done in every patient with Sneddon's syndrome, as it could impact therapy.

    This study examined the incidence and risk factors for gastrointestinal (GI) bleeding after spontaneous intracerebral hemorrhage (ICH). The available medical records of patients with ICH admitted from June 2008 to December 2009 for any episode of GI bleeding, possible precipitating factors and administration of ulcer prophylaxis were reviewed. The prevalence of GI bleeding was 26.7%, including 3 cases of severe GI bleeding (0.35%). Patients with GI bleeding had significantly longer hospital stay and higher in-hospital mortality compared with patients without GI bleeding. Multivariate logistic regression analyses showed that age, Glasgow Coma Scale scores, sepsis and ICH volume were independent predictors of GI bleeding. About 63.4% of patients with ICH received stress ulcer prophylaxis. GI bleeding occurred frequently after ICH, but severe events were rare. Age, Glasgow Coma Scale score, sepsis and ICH volume were independent predictors of GI bleeding occurring after ICH.

    Full Text Available Intracerebral hemorrhage (ICH is a devastating type of stroke with a substantial public health impact. Currently, there is no effective treatment for ICH. The purpose of the study was to evaluate whether the post-injury administration of Resveratrol confers neuroprotection in a pre-clinical model of ICH. To this end, ICH was induced in adult male CD1 mice by collagenase injection method. Resveratrol (10 mg/kg or vehicle was administered at 30 min post-induction of ICH and the neurobehavioral outcome, neurodegeneration, cerebral edema, hematoma resolution and neuroinflammation were assessed. The Resveratrol treatment significantly attenuated acute neurological deficits, neurodegeneration and cerebral edema after ICH in comparison to vehicle treated controls. Further, Resveratrol treated mice exhibited improved hematoma resolution with a concomitant reduction in the expression of proinflammatory cytokine, IL-1β after ICH. Altogether, the data suggest the efficacy of post-injury administration of Resveratrol in improving acute neurological function after ICH.

    The authors studied patients who presented depression and apathy following intracerebral hemorrhage (ICH). Twelve patients who were admitted in our hospital were divided into two groups according to the presence of post-stroke depression (PSD). Five patients with PSD are in group A, and another seven patients without PSD are in group B. Zung-self depression scale (SDS) and apathy scale were used for screening of depression and apathy. PSD was recognized in 5 (42%) of patients following ICH. Single photon emission tomography (SPECT) suggested the reduction of cerebral blood flow (CBF) in the frontal lobe in all patients of the group A (100%), whereas only 29% of patients of the group B. The reduction of CBF in the frontal lobe might be involved in the mechanism of depression following ICH in subacute stage. (author)

    This paper aimed to test the hypothesis that intraventricular extension of spontaneous intracerebral hemorrhage (ICH) in the absence of hydrocephalus is not associated with increased mortality or severe disability. We performed a retrospective consecutive cohort study of patients with primary spontaneous ICH who were admitted to a single institution. Multivariate logistic regression analysis was used to assess the association of each variable with functional outcome as measured by the modified Rankin Scale (mRS). A total of 164 patients met our inclusion criteria and were included in the study. Only hydrocephalus (p=0.002) and hematoma volume (p=0.006) were significantly associated with mortality or poor functional outcome (mRS of 3 to 6). In contrast, the presence of intraventricular hematoma was not independently associated with poor functional outcome. The presence of intraventricular extension of ICH in the absence of hydrocephalus may not increase mortality or disability. Copyright © 2016 Elsevier Ltd. All rights reserved.

  13. Stereotactic aspiration versus craniotomy for primary intracerebral hemorrhage: a meta-analysis of randomized controlled trials.

    Directory of Open Access Journals (Sweden)

    Jia-Wei Wang

    Full Text Available BACKGROUND: A wealth of evidence based on the randomized controlled trials (RCTs has indicated that surgery may be a better choice in the management of primary intracerebral hemorrhage (ICH compared to conservative treatment. However, there is considerable controversy over selecting appropriate surgical procedures for ICH. Thus, this meta-analysis was performed to assess the effects of stereotactic aspiration compared to craniotomy in patients with ICH. METHODS: According to the study strategy, we searched PUBMED, EMBASE and Cochrane Central Register of Controlled Trials. Other sources such as the internet-based clinical trial registries, relevant journals and the lists of references were also searched. After literature searching, two investigators independently performed literature screening, assessment of quality of the included trials and data extraction. The outcome measures included death or dependence, total risk of complication, and the risk of rebleeding, gastrointestinal hemorrhage and systematic infection. RESULTS: Four RCTs with 2996 participants were included. The quality of the included trials was acceptable. Stereotactic aspiration significantly decreased the odds of death or dependence at the final follow-up (odds ratio (OR: 0.80, 95% confidence interval (CI: 0.69-0.93; P = 0.004 and the risk of intracerebral rebleeding (OR: 0.44, 95% CI: 0.26-0.74; P = 0.002 compared to craniotomy with no significant heterogeneity among the study results. CONCLUSIONS: The present meta-analysis provides evidence that the stereotactic aspiration may be associated with a reduction in the odds of being dead or dependent in primary ICH, which should be interpreted with caution. Further trials are needed to identify those patients most likely to benefit from the stereotactic aspiration.

    Previous research investigating outcomes after pediatric intracerebral hemorrhage (ICH) has generally been limited to global and sensorimotor outcomes. This study examined cognitive outcomes after spontaneous ICH in school-aged children with serial assessments over 2 years after stroke. Seven children (age range 6-16y, median 13; six males, one female; 57% white, 43% black) presenting with spontaneous ICH (six arteriovenous malformations) were assessed at 3 months, 12 months, and 24 months after stroke. The Pediatric Stroke Outcome Measure (PSOM) quantified neurological outcome and Wechsler Intelligence Scales measured cognitive outcomes: verbal comprehension, perceptual reasoning, working memory, and processing speed. PSOM scales showed improved neurological function over the first 12 months, with mild to no sensorimotor deficits and moderate overall deficits at 1- and 2-year follow-ups (median 2-year sensorimotor PSOM=0.5, total PSOM=1.5). Changes in cognitive function indicated a different trajectory; verbal comprehension and perceptual reasoning improved over 24 months; low performance was sustained in processing speed and working memory. Age-normed centile scores decreased between 1- and 2-year follow-ups for working memory, suggesting emerging deficits compared with peers. Early and serial cognitive testing in children with ICH is needed to assess cognitive functioning and support children in school as they age and cognitive deficits become more apparent and important for function. In children with intracerebral hemorrhage (ICH), motor function improved between 3 months and 24 months. Improvements in cognitive function were variable between 3 months and 24 months. Working memory centiles declined, suggesting emerging deficits compared with peers. Processing speed improved but remained significantly below the 50th centile. Cognitive impact of ICH may increase with age in children. © 2017 Mac Keith Press.

    Full Text Available Objectives: Intracerebral hemorrhage (ICH is one of the most mortal subtypes of stroke. Due to the angiogenic, neurotropic, and vessel-dilating properties of basic fibroblast growth factor (bFGF in the brain, role of bFGF has been investigated in a number of neurological disorders. So far, there is only study about serum bFGF levels in patients with ICH. The first aim of the present research is to investigate whether increased serum bFGF in patients with ICH. Also, second aim was to study the association between serum levels of bFGF and clinical status in patients with ICH.Materials and methods: We measured the serum levels of bFGF in 30 patients with ICH during acute period. Age and sex matched healthy subjects (n=30 were included in controls. Serum bFGF levels were measured using an enzyme-linked immunosorbent assay method.Results: The patients with intracerebral hemorrhage had higher serum levels of bFGF when compared with the healthy controls (12.89±3.23 ng/ml, 5.28±1.75 ng/ml; p=0.001. No statistically significant difference was determined between bFGF levels of the patients who died as compared to the patients who lived (13.49±4.13 ng/ml; 12.43±3.43 ng/ml, p>0.05. No statistically significant difference was found between bFGF levels of the patients with intraventricular hemorrhage as compared to the patients without intraventricular hemorrhage (13.54±3.92 ng/ml; 12.24±2.29 ng/ml, p>0.05. There was no correlation between serum bFGF, hematoma volume, Gloskow coma scale, and National Institutes of Health stroke scale (p>0.05.Conclusion: The increased bFGF level may be one of the mechanisms that lead to angiogenesis and neuroprotection after ICH in human. .

    A bibliometric uses the citation count of an article to determine its impact on the clinical world. There is a paucity of literature concerning top article citations on spontaneous intracerebral hemorrhage (ICH). The main objective of this investigation was to bridge this gap and to provide understanding of the trends on the most influential articles written on this subject. The Scopus Library database was searched to determine the citations of all articles published on spontaneous ICH. Articles that focused on other forms of ICH, such as trauma-related hemorrhages, subarachnoid hemorrhages, or hemorrhages caused by anticoagulation, vascular malformations, or cavernomas, were excluded from our list. The articles were divided into 2 groups: "specific" articles, which focused specifically on spontaneous ICH, and "generalized" articles, which were about ICH in general, including spontaneous as well as other forms of ICH. We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. J. Broderick was the author with most publications in the list (n = 21). The largest subset of spontaneous ICH articles was published in the 5-year periods from 1996 to 2000 and 2001 to 2005 (n = 27 each). The United States had the highest number of articles (n = 49). The journal with the highest number of top 100 cited articles was Stroke, with 39, followed by Neurology with 16. Our study identifies the trends related to spontaneous ICH by analyzing the citation frequency of the most-cited articles in the field. Copyright © 2017 Elsevier Inc. All rights reserved.

    Acupuncture has been widely used as a treatment for stroke in China for a long time. Recently, studies have demonstrated that electroacupuncture (EA) can accelerate intracerebral hemorrhage (ICH)-induced angiogenesis in rats. In the present study, we investigated the effect of EA on neurobehavioral function and brain injury in ICH rats. ICH was induced by stereotactic injection of collagenase type I and heparin into the right caudate putamen. Adult ICH rats were randomly divided into the following three groups: model control group (MC), EA at non-acupoint points group (non-acupoint EA) and EA at Baihui and Dazhui acupoints group (EA). The neurobehavioral deficits of ICH rats were assessed by modified neurological severity score (mNSS) and gait analysis. The hemorrhage volume and glucose metabolism of hemorrhagic foci were detected by PET/CT. The expression levels of MBP, NSE and S100-B proteins in serum were tested by ELISA. The histopathological features were examined by haematoxylin-eosin (H&E) staining. Apoptosis-associated proteins in the perihematomal region were observed by immunohistochemistry. EA treatment significantly promoted the recovery of neurobehavioral function in ICH rats. Hemorrhage volume reduced in EA group at day 14 when compared with MC and non-acupoint EA groups. ELISA showed that the levels of MBP, NSE and S100-B in serum were all down-regulated by EA treatment. The brain tissue of ICH rat in the EA group was more intact and compact than that in the MC and non-acupoint groups. In the perihematomal regions, the expression of Bcl-2 protein increased and expressions of Caspase-3 and Bax proteins decreased in the EA group vs MC and non-acupoint EA groups. Our data suggest that EA treatment can improve neurobehavioral function and brain injury, which were likely connected with the absorption of hematoma and regulation of apoptosis-related proteins.

    Full Text Available Background: Hypertension damages small vessels, resulting in both lacunar infarction and subcortical intracerebral hemorrhage (ICH. Substance abuse has also been linked to small vessel pathology. This study explores whether the use of specific substances (eg., cocaine, tobacco is associated with subcortical ICH over ischemia in hypertensive individuals.Methods: Patients with hypertension, admitted with lacunar infarcts (measuring 1 drink per day (women, >2 drinks per day (men. Logistic regression was performed with ICH as the dependent variable comparing those presenting with ICH to those presenting with ischemia.Results: Of the 580 patients included in analysis, 217 (37% presented with ICH. The average age was similar between the two groups (64.7 versus 66.3 years. Illicit/controlled drug use was associated with a significantly increased risk of ICH over stroke in unadjusted models (25% versus 15%, p=0.02, with the largest effect seen in users ≥65 years old (not statistically significant. Smoking was associated with ischemia over ICH in a dose-dependent manner: any history of smoking OR 1.84, CI 1.19-2.84; current use OR 2.23, CI 1.37-3.62; heavy use OR 2.48, CI 1.50-4.13. Alcohol use was not preferentially associated with either outcome (p=0.29.Conclusions: In hypertensive patients, tobacco use is associated with an increased risk of subcortical ischemia compared to ICH; while use of illicit/controlled substances appears to be predictive of hemorrhage.

    Purpose: To explore the dynamic changes of rCBF of aphasic patients and its correlation with clinical findings. Methods: 32 dominant lateral hypertensive intracerebral hemorrhagic patients underwent the language function evaluation, rCBF tomographic imaging and CT scans. Semiquantitative analysis was used. Results: 1) 19 of 32 cases were aphasia while 13 were not. 2) There was a close correlation between aphasia and the size and location of hematoma. 3) There was only hemonrrhagic foci demonstrated with CT while multiple and extensive cortical hypo-perfused area were found in SPECT, especially in aphasic cases. Frontal and temporal lobes of each aphasia were involved 100%. 4) The rCBF ratio in both Broca's and Wernicke's areas of aphasias were lower than those of non-aphasias (t = 4.31, 5.52, P < 0.001). The degree of rCBF decrement in Wernicke's area varied with different aphasic types, among which the rCBF of sensory aphasia was the lowest (t 2.53, P<0.05). 5) 10 aphasias were followed with SPECT, CT and clinic evaluation 1 week, 1 month and 3 months after hemorrhage respectively. The rCBF ratios in cerebral cortex of 5 recovery cases increased gradually, but not in 5 not recovered cases. Conclusions: SPECT was superior to CT, it can provide useful information for diagnosing and staging aphasias, especially in early stage, and can also assess the prognosis of the disease

    Full Text Available BackgroundEarly accurate outcome prognostication for patients with intracerebral hemorrhage (ICH and accompanying intraventricular hemorrhage (IVH is often challenging (1. Acute hydrocephalus often contributes to a poor clinical exam (2 and can portend significant morbidity and mortality (3. Accordingly, the inpatient neurologist may feel inclined to recommend limitations of care for an ICH patient admitted with a large IVH burden and poor exam.Case presentationWe present a patient with significant IVH and minimal ICH who deteriorated rapidly to coma after presentation. Despite this exam, an initially non-functioning diversion of cerebrospinal fluid (CSF and temporary halt of further attempts of CSF diversion in the setting of an early “do not resuscitate order,” our patient gradually improved and, with supportive ICU care and rehabilitation, was able to communicate and ambulate with assistance at 12 weeks.ConclusionPatients with ICH with IVH do have the capacity to improve dramatically even with relatively conservative management. Unless previous limitations of care exist, we recommend that early judgments of prognosis for patients with ICH and/or IVH should be delayed for at least 72 h until the patient’s clinical trajectory over time is better understood.

    We sought to quantify perfusion changes associated to acute spontaneous intracerebral hemorrhage (SICH) by means of computed tomography perfusion (CTP) imaging. We studied 89 patients with supratentorial SICH at admission CT by using CTP scanning obtained within 24 h after symptom onset. Regional cerebral blood flow (rCBF), cerebral blood volume (rCBV) and mean transit time (rMTT) levels were measured in four different regions of interest manually outlined on CT scan: (1) hemorrhagic core; (2) perihematomal low-density area; (3) 1 cm rim of normal-appearing brain tissue surrounding the perilesional area; and (4) a mirrored area, including the clot and the perihematomal region, located in the non-lesioned contralateral hemisphere. rCBF, rCBV, and rMTT mean levels showed a centrifugal distribution with a gradual increase from the core to the periphery (p 20 ml) hematomas (p<0.01 and p <0.02, respectively). Multi-parametric CTP mapping of acute SICH indicates that perfusion values show a progressive improvement from the core to the periphery. In the first 24 h, perihemorrhagic region was hypoperfused with CTP values which were not suggestive of ischemic penumbra destined to survive but more likely indicative of edema formation. These findings also argue for a potential influence of early amounts of bleeding on perihematomal hemodynamic abnormalities. (orig.)

    Intracerebral hemorrhage (ICH) usually affects older humans but almost no experimental studies have assessed aged animals. We address how aging alters inflammation, neuron death and lesion resolution after a hemorrhage in the rat striatum. In the normal aged brain, microglia displayed a 'dystrophic' phenotype, with shorter cellular processes and large gaps between adjacent cells, and there was more astrocyte reactivity. The ICH injury was monitored as hematoma volume and number of dying neurons at 1 and 3 days, and the volume of the residual lesion, ventricles and lost tissue at 28 days. Inflammation at 1 and 3 days was assessed from densities of microglia with resting vs. activated morphologies, or expressing the lysosomal marker ED1. Despite an initial delay in neuron death in aged animals, by 28 days, there was no difference in neuron density or volume of tissue lost. However, lesion resolution was impaired in aged animals and there was less compensatory ventricular expansion. At 1 day after ICH, there were fewer activated microglia/macrophages in the aged brain, but by 3 days there were more of these cells at the edge of the hematoma and in the surrounding parenchyma. In both age groups a glial limitans had developed by 3 days, but astrocyte reactivity and the spread of activated microglia/macrophages into the surrounding parenchyma was greater in the aged. These findings have important implications for efforts to reduce secondary injury after ICH and to develop anti-inflammatory therapies to treat ICH in aged humans.

    Full Text Available OBJECTIVE: 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA reductase inhibitors, or statins, have been associated with improved clinical outcomes after ischemic stroke and subarachnoid hemorrhage, but with an increased risk of incidental spontaneous intracerebral hemorrhage (ICH. We investigated whether the statin use before ICH, was associated with functional independence, 90 days after treatment. METHOD: We analyzed 124 consecutive ICH patients with 90-day outcome data who were enrolled in a prospective cohort study between 2006 and 2009. Eighty-three patients were included in this study. Among ICH survivors, univariate Cox regression models and Kaplan-Meier plots were used to determine subject characteristics that were associated with an increased risk of recurrence. Statin usage was determined through interviewing the patient at the time of ICH and confirmed by reviewing their medical records. Independent status was defined as Glasgow Outcome Scale grades 4 or 5. RESULTS: Statins were used by 20 out of 83 patients (24% before ICH onset. There was no effect from pre-ICH statin use on functional independence rates (28% versus 29%, P=0.84 or mortality (46% versus 45%, P=0.93. CONCLUSION: Pre-ICH statin use is not associated with changes to ICH functional outcome or mortality.

    Endoscopic evacuation of hematoma (EEH) has recently been applied to treat patients with spontaneous intracerebral hemorrhage (sICH). Intraoperative active bleeding (IAB), which is occasionally observed in EEH, might lead to greater blood loss, further brain damage, and more postoperative recurrent hemorrhage. However, no definite predictor of IAB has been established. Because the spot sign is associated with other hemorrhagic complications, we aimed to evaluate whether it predicts IAB. We retrospectively assessed the incidence and risk factors of IAB, including the spot sign, in 127 sICH patients who underwent EEH within 6 hours after computed tomography angiography at our institution between June 2009 and December 2017. The study included 53 women and 74 men with an average age of 66.7 ± 11.8 years. IAB occurred in 40 (31.5%) of the 127 patients, and it was more frequent in patients with the spot sign than in patients without it (14/24 [58.3%] vs. 26/103 [25.2%]; P = 0.003). Multivariable regression analyses suggested that the spot sign was an independent predictor of IAB (odds ratio [OR], 3.02; 95% confidence interval [CI], 1.10-8.30; P = 0.03). In addition, earlier surgery gradually increased the risk of IAB, and surgery within 4 hours of onset was an independent risk factor (OR, 4.34; 95% CI, 1.12-16.9; P = 0.03, referring to postonset 8 hours or more). The spot sign and early surgery were independent predictors of IAB in EEH for sICH. In patients with sICH and spot sign, complete treatment of IAB by electrocoagulation might be important for minimizing surgical complications. Copyright © 2018 Elsevier Inc. All rights reserved.

    Minimally invasive endoscope-assisted (MIE) evacuation of spontaneous intracerebral hemorrhage (ICH) is simple and effective, but the limited working space may hinder meticulous hemostasis and might lead to rebleeding. Management of intraoperative hemorrhage is therefore a critical issue of this study. This study presents experience in the treatment of patients with various types of ICH by MIE evacuation followed by direct local injection of FloSeal Hemostatic Matrix (Baxter Healthcare Corp, Fremont, CA, USA) for hemostasis. The retrospective nonrandomized clinical and radiology-based analysis enrolled 42 patients treated with MIE evacuation of ICH followed by direct local injection of FloSeal Hemostatic Matrix. Rebleeding, morbidity, and mortality were the primary endpoints. The percentage of hematoma evacuated was calculated from the pre- and postoperative brain computed tomography (CT) scans. Extended Glasgow Outcome Scale (GOSE) was evaluated at 6 months postoperatively. Forty-two ICH patients were included in this study, among these, 23 patients were putaminal hemorrhage, 16 were thalamic ICH, and the other three were subcortical type. Surgery-related mortality was 2.4%. The average percentage of hematoma evacuated was 80.8%, and the rebleeding rate was 4.8%. The mean operative time was 102.7 minutes and the average blood loss was 84.9 mL. The mean postoperative GOSE score was 4.55 at 6-months' follow-up. This study shows that local application of FloSeal Hemostatic Matrix is safe and effective for hemostasis during MIE evacuation of ICH. In our experience, this shortens the operation time, especially in cases with intraoperative bleeding. A large, prospective, randomized trial is needed to confirm the findings. Copyright © 2017.

    Mechanisms, acute management, and outcomes for patients who experience intracerebral hemorrhage may differ from patients with ischemic stroke. Studies of very early rehabilitation have been mainly undertaken in patients with ischemic stroke, and it is unknown if benefits apply to those with intracerebral hemorrhage. We hypothesized that early rehabilitation, within 48 hours of stroke, would improve survival and functional outcomes in patients with intracerebral hemorrhage. This was a multicenter, randomized controlled study, with blinded assessment of outcome at 3 and 6 months. Eligible patients were randomized to receive standard care or standard care plus early rehabilitation. Primary outcome includes survival. Secondary outcomes includes health-related quality of life using the 36-item Short Form Questionnaire, function measured with the modified Barthel Index, and anxiety measured with the Zung Self-Rated Anxiety Scale. Two hundred forty-three of 326 patients were randomized (mean age, 59 years; 56% men). At 6 months, patients receiving standard care were more likely to have died (adjusted hazard ratio, 4.44; 95% confidence interval [CI], 1.24-15.87); for morbidity outcomes, a 6-point difference in the Physical Component Summary score of the 36-item Short Form Questionnaire (95% CI, 4.2-8.7), a 7-point difference for the Mental Component Summary score (95% CI, 4.5-9.5), a 13-point difference in Modified Barthel Index scores (95% CI, 6.8-18.3), and a 6-point difference in Self-Rating Anxiety Scale scores (95% CI, 4.4-8.3) was reported in favor of the intervention groups. For the first time, we have shown that commencing rehabilitation within 48 hours of intracerebral hemorrhage improves survival and functional outcomes at 6 months after stroke in hospitalized patients in China. http://www.chictr.org/en.

Because both surgical techniques are of a minimally invasive nature, they have attracted greater attention in recent years. However, evidence comparing the curative effect of MIPD and ES has been uncertain. The indication for MIPD or ES has been uncertain till now. In the present study, 112 patients with spontaneous ICH in basal ganglia who received MIPD or ES were reviewed retrospectively. Baseline parameters prior to the operation, evacuation rate (ER, perihematoma edema, postoperative complications, and rebleeding incidences were collected. Moreover, 1-year postictus, the long-term functional outcomes of patients with regard to hematoma volume (HV or Glasgow Coma Scale (GCS score were judged, respectively, by the case fatality, Glasgow Outcome Scale (GOS, Barthel Index (BI, and modified Rankin Scale (mRS. The ES group had a higher ER than the MIPD group on postoperative day 1. The MIPD group had fewer adverse outcomes, which included less perihematoma edema, anesthetic time, and blood loss, than the ES group. The functional outcomes represented by GOS, BI, and mRS were better in the MIPD group than in the ES group for patients with HV 30–60 mL or GCS score 9–14. These results indicate that ES is more effective in evacuating hematoma in basal ganglia, while MIPD is less invasive than ES. Patients with HV 30–60 mL or GCS score 9–14 may benefit more from the MIPD

    Full Text Available Pulmonary complications and closely related with them systemic functional-biochemical abnormalities are the most common complications of cerebral stroke. The purpose of the work was to research functional-biochemical parameters of respiratory function and to find it’s association with morphological changes in the lungs because of intracerebral hemorrhage. 37 sectional observations in patients who die of intracerebral hemorrhage were analized. It was conducted analysis of morphological transformations and retrospective analysis of functional-biochemical findings of respiratory functions, in order to detect changes of systemic hemodynamics, oxygen balance and ion-osmotic one and acid-alkaline status. The results of the study. The changes of blood gas composition and acid-alkaline status are registered in the lungs in the background of microcirculation disturbance from the first hours of development of intracerebral hemorrhage. During the first days of the onset of disease the partial oxygen pressure in arterial blood (РаО2 decreased 50,88% in comparison with the calculated normative findings. Partial pressure of carbon dioxide (РаСО2 in the arterial blood rosed by 52,17%. Without conducting artificial lung ventilation PO2 in venous blood decreased by 45,9%, and PCO2 increased by 40%. I has been marked a decrease in the oxygen capacity of the blood, due to the reduction of hemoglobin content in the blood to 103,7 minus 2 g/l and the concomitant decline in hematocrit up to 0,24-0,3. Deficit of the foundations has averaged from -6 to -10 mmol/l. These changes have led to a impression of the respiratory and metabolic acidosis, with a significant increase in the concentration of hydrogen ions.

    Hypertension damages small vessels, resulting in both lacunar infarction and subcortical intracerebral hemorrhage (ICH). Substance abuse has also been linked to small vessel pathology. This study explores whether the use of specific substances (e.g., cocaine, tobacco) is associated with subcortical ICH over ischemia in hypertensive individuals. Patients with hypertension, admitted with lacunar infarcts (measuring 1 drink per day (women), >2 drinks per day (men). Logistic regression was performed with ICH as the dependent variable comparing those presenting with ICH to those presenting with ischemia. Of the 580 patients included in analysis, 217 (37%) presented with ICH. The average age was similar between the two groups (64.7 versus 66.3 years). Illicit/controlled drug use was associated with a significantly increased risk of ICH over stroke in unadjusted models (25 versus 15%, p = 0.02), with the largest effect seen in users ≥65 years old (not statistically significant). Smoking was associated with ischemia over ICH in a dose-dependent manner: any history of smoking OR 1.84, CI 1.19-2.84; current use OR 2.23, CI 1.37-3.62; heavy use OR 2.48, CI 1.50-4.13. Alcohol use was not preferentially associated with either outcome (p = 0.29). In hypertensive patients, tobacco use is associated with an increased risk of subcortical ischemia compared to ICH, while use of illicit/controlled substances appears to be predictive of hemorrhage.

    In spontaneous intracerebral hemorrhage (ICH), black hole sign has been proposed as a promising imaging marker that predicts hematoma expansion in patients with ICH. The aim of our study was to investigate whether admission CT black hole sign predicts hematoma growth in patients with ICH. From July 2011 till February 2016, patients with spontaneous ICH who underwent baseline CT scan within 6 h of symptoms onset and follow-up CT scan were recruited into the study. The presence of black hole sign on admission non-enhanced CT was independently assessed by 2 readers. The functional outcome was assessed using the modified Rankin Scale (mRS) at 90 days. Univariate and multivariable logistic regression analyses were performed to assess the association between the presence of the black hole sign and functional outcome. A total of 225 patients (67.6% male, mean age 60.3 years) were included in our study. Black hole sign was identified in 32 of 225 (14.2%) patients on admission CT scan. The multivariate logistic regression analysis demonstrated that age, intraventricular hemorrhage, baseline ICH volume, admission Glasgow Coma Scale score, and presence of black hole sign on baseline CT independently predict poor functional outcome at 90 days. There are significantly more patients with a poor functional outcome (defined as mRS ≥4) among patients with black hole sign than those without (84.4 vs. 32.1%, p black hole sign independently predicts poor outcome in patients with ICH. Early identification of black hole sign is useful in prognostic stratification and may serve as a potential therapeutic target for anti-expansion clinical trials. © 2018 S. Karger AG, Basel.

    OBJECTIVE In patients with spontaneous intracerebral hemorrhage (sICH), postoperative recurrent hemorrhage (PRH) is one of the most severe complications after endoscopic evacuation of hematoma (EEH). However, no predictors of this complication have been identified. In the present study, the authors retrospectively investigated whether PRH can be preoperatively predicted by the presence of the spot sign on CT scans. METHODS In total, 143 patients with sICH were treated by EEH between June 2009 and March 2017, and 127 patients who underwent preoperative CT angiography were included in this study. Significant correlations of PRH with the patients' baseline, clinical, and radiographic characteristics, including the spot sign, were evaluated using multivariable logistic regression models. RESULTS The incidence of and risk factors for PRH were assessed in 127 patients with available data. PRH occurred in 9 (7.1%) patients. Five (21.7%) cases of PRH were observed among 23 patients with the spot sign, whereas only 4 (3.8%) cases of PRH occurred among 104 patients without the spot sign. The spot sign was the only independent predictor of PRH (OR 5.81, 95% CI 1.26-26.88; p = 0.02). The following factors were not independently associated with PRH: age, hypertension, poor consciousness, antihemostatic factors (thrombocytopenia, coagulopathy, and use of antithrombotic drugs), the location and size of the sICH, other radiographic findings (black hole sign and blend sign), surgical duration and procedures, and early surgery. CONCLUSIONS The spot sign is likely to be a strong predictor of PRH after EEH among patients with sICH. Complete and careful control of bleeding in the operative field should be ensured when surgically treating such patients. New surgical strategies and procedures might be needed to improve these patients' outcomes.

    Animal studies testing whether therapeutic hypothermia is neuroprotective after intracerebral hemorrhage (ICH) have been inconclusive. In rodents, ICH is often produced in the striatum by infusing collagenase, which causes prolonged hemorrhaging from multiple vessels. Our previous data shows that this bleeding (hematoma) is worsened by systemic hypothermia given soon after collagenase infusion. In this study we hypothesized that localized brain hypothermia would also aggravate bleeding in this model (0.2 U of collagenase in 1.2 μL of saline). We also evaluated cooling after intrastriatal thrombin infusion (1 U in 30 μL of saline)-a simplified model of ICH thought to cause bleeding. Focal hypothermia was achieved by flushing cold water through an implanted cooling device attached to the skull underneath the temporalis muscle of adult rats. Previous work and data at this time shows this method cools the striatum to ∼33°C, whereas the body remains normothermic. In comparison to normothermic groups, cooling significantly worsened bleeding when instituted at 6 hours (∼94 vs. 42 μL, p=0.018) and 12 hours (79 vs. 61 μL, p=0.042) post-ICH (24-hour survival), but not after a 24-hour delay (36-hour survival). Rats were cooled until euthanasia when hematoma size was determined by a hemoglobin-based spectrophotometry assay. Cooling did not influence cerebral blood volume after just saline or thrombin infusion. The latter is explained by the fact that thrombin did not cause bleeding beyond that caused by saline infusion. In summary, local hypothermia significantly aggravates bleeding many hours after collagenase infusion suggesting that bleeding may have confounded earlier studies with hypothermia. Furthermore, these findings serve as a cautionary note on using cooling even many hours after cerebral bleeding.

    Brain iron overload is involved in brain injury after intracerebral hemorrhage (ICH). There is evidence that systemic administration of minocycline reduces brain iron level and improves neurological outcome in experimental models of hemorrhagic and ischemic stroke. However, there is evidence in cerebral ischemia that minocycline is not protective in aged female animals. Since most ICH research has used male models, this study was designed to provide an overall view of ICH-induced iron deposits at different time points (1 to 28 days) in aged (18-month old) female Fischer 344 rat ICH model and to investigate the neuroprotective effects of minocycline in those rats. According to our previous studies, we used the following dosing regimen (20 mg/kg, i.p. at 2 and 12 h after ICH onset followed by 10 mg/kg, i.p., twice a day up to 7 days). T2-, T2 ⁎ -weighted and T2 ⁎ array MRI was performed at 1, 3, 7 and 28 days to measure brain iron content, ventricle volume, lesion volume and brain swelling. Immunohistochemistry was used to examine changes in iron handling proteins, neuronal loss and microglial activation. Behavioral testing was used to assess neurological deficits. In aged female rats, ICH induced long-term perihematomal iron overload with upregulated iron handling proteins, neuroinflammation, brain atrophy, neuronal loss and neurological deficits. Minocycline significantly reduced ICH-induced perihematomal iron overload and iron handling proteins. It further reduced brain swelling, neuroinflammation, neuronal loss, delayed brain atrophy and neurological deficits. These effects may be linked to the role of minocycline as an iron chelator as well as an inhibitor of neuroinflammation. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Background. Spontaneous intracerebral hemorrhage (ICH is common and causes significant mortality and morbidity. To date, optimal medical and surgical intervention remains uncertain. A lack of definitive benefit for operative management may be attributable to adverse surgical effect, collateral tissue injury. This is particularly relevant for ICH in dominant, eloquent cortex. Minimally invasive surgery (MIS offers the potential advantage of reduced collateral damage. MIS utilizing a parafascicular approach has demonstrated such benefit for intracranial tumor resection. Methods. We present a case of dominant hemisphere spontaneous ICH evacuated via the minimally invasive subcortical parafascicular transsulcal access clot evacuation (Mi SPACE model. We use this report to introduce Mi SPACE and to examine the application of this novel MIS paradigm. Case Presentation. The featured patient presented with a left temporal ICH and severe global aphasia. The hematoma was evacuated via the Mi SPACE approach. Postoperative reassessments showed significant improvement. At two months, bedside language testing was normal. MRI tractography confirmed limited collateral injury. Conclusions. This case illustrates successful application of the Mi SPACE model to ICH in dominant, eloquent cortex and subcortical regions. MRI tractography illustrates collateral tissue preservation. Safety and feasibility studies are required to further assess this promising new therapeutic paradigm.

Retrospective analysis of data collected in a prospective cohort study. Hospital. Consecutive sample of 200 patients with primary lobar ICH and 75 patients with deep hemispheric ICH. Presence of SDH and mortality. Subdural hematoma was present in 40 of 200 patients (20%) with primary lobar ICH. By contrast, SDH was not present in any of 75 consecutive patients with deep hemispheric ICH (P Subdural hematoma thickness more than 5 mm was an independent predictor of increased 30-day mortality (OR, 7.60; 95% CI, 1.86-30.99; P = .005) after controlling for other factors including ICH volume. Further analysis showed that the effect of SDH on mortality depended on ICH volume, with larger odds for mortality in those with low ICH volume (OR, 12.85; 95% CI, 2.42-68.23; P = .003 for those with ICH volume subdural space, may be the pathogenic mechanism.

    Formation of brain edema after intracerebral hemorrhage (ICH) is highly associated with its poor outcome. However, the relationship between cerebral edema and behavioral deficits has not been thoroughly examined in the preclinical setting. Hence, this study aimed to evaluate the ability of common sensorimotor tests to predict the extent of brain edema in two mouse models of ICH. One hundred male CD-1 mice were subjected to sham surgery or ICH induction via intrastriatal injection of either autologous blood (30 μL) or bacterial collagenase (0.0375U or 0.075U). At 24 and 72 h after surgery, animals underwent a battery of behavioral tests, including the modified Garcia neuroscore (Neuroscore), corner turn test (CTT), forelimb placing test (FPT), wire hang task (WHT) and beam walking (BW). Brain edema was evaluated via the wet weight/dry weight method. Intrastriatal injection of autologous blood or bacterial collagenase resulted in a significant increase in brain water content and associated sensorimotor deficits (p<0.05). A significant correlation between brain edema and sensorimotor deficits was observed for all behavioral tests except for WHT and BW. Based on these findings, we recommend implementing the Neuroscore, CTT and/or FPT in preclinical studies of unilateral ICH in mice. Copyright © 2014 Elsevier B.V. All rights reserved.

    It has been shown that 3 days of 62 mg/kg/day deferoxamine infusion (maximum dose not to exceed 6000 mg/day) is safe and tolerated by intracerebral hemorrhage (ICH) patients. The aim of this study was to investigate the efficacy of deferoxamine mesylate for edema resolution and hematoma absorption after ICH. From February 2013 to May 2014, spontaneous ICH patients diagnosed by computed tomography (CT) within 18 hours of onset were evaluated. Patients were randomly divided into two groups: an experimental group and a control group. The treatment of the two groups was similar except that the experimental group received deferoxamine mesylate. Patients were evaluated by CT and neurology scale at the time of admission, and on the fourth, eighth, and fifteenth day (or at discharge) after admission. Patients were followed up for the first 30 days and clinical data of the two groups were compared. Forty-two patients completed 30 days of follow-up by May 2014; 21 cases in the experimental group and 21 cases in the control group. The control group's relative edema volume on the fifteenth day (or discharge) was 10.26 ± 17.54, which was higher than the experimental group (1.91 ± 1.94; P edema volume on the fourth, eighth, and fifteenth day (or discharge) was higher than the experimental group (P edema after ICH, although further investigation is required to form definitive conclusions.

    Spontaneous intracerebral hemorrhage is a type of stroke associated with poor outcomes. Mortality is elevated, especially in the acute phase. From a pathophysiological point of view the bleeding must traverse different stages dominated by the possibility of re-bleeding, edema, intracranial hypertension, inflammation and neurotoxicity due to blood degradation products, mainly hemoglobin and thrombin. Neurological deterioration and death are common in early hours, so it is a true neurological-neurosurgical emergency. Time is brain so that action should be taken fast and accurately. The most significant prognostic factors are level of consciousness, location, volume and ventricular extension of the bleeding. Nihilism and early withdrawal of active therapy undoubtedly influence the final result. Although there are no proven therapeutic measures, treatment should be individualized and guided preferably by pathophysiology. The multidisciplinary teamwork is essential. Results of recently completed studies have birth to promising new strategies. For correct management it’s important to establish an orderly and systematic strategy based on clinical stabilization, evaluation and establishment of prognosis, avoiding secondary insults and adoption of specific individualized therapies, including hemostatic therapy and intensive control of elevated blood pressure. Uncertainty continues regarding the role of surgery. PMID:26261773

    Intracerebral hemorrhage (ICH) at high altitude is not well understood to date. This study investigates the effects of high altitude on ICH, and examines the acute neuroprotection of hyperbaric oxygen (HBO) therapy against high-altitude ICH. Minipigs were placed in a hypobaric chamber for 72 h before the operation. ICH was induced by an infusion of autologous arterial blood (3 ml) into the right basal ganglia. Animals in the high-altitude ICH group received HBO therapy (2.5 ATA for 60 min) 30 min after ICH. Blood gas, blood glucose and brain tissue oxygen partial pressure (PbtO2) were monitored continuously for animals from all groups, as were microdialysis products including glucose, lactate, pyruvate and glutamate in perihematomal tissue from 3 to 12 h post-ICH. High-altitude ICH animals showed significantly lower PbtO2, higher lactate/pyruvate ratio (LPR) and glutamate levels than low-altitude ICH animals. More severe neurological deficits, brain edema and neuronal damage were also observed in high-altitude ICH. After HBO therapy, PbtO2 was significantly increased and LPR and glutamate levels were significantly decreased. Brain edema, neurological deficits and neuronal damage were also ameliorated. The data suggested a more serious disturbance of tissue oxygenation and cerebral metabolism in the acute stage after ICH at high altitude. Early HBO treatment reduced acute brain injury, perhaps through a mechanism involving the amelioration of the derangement of cerebral oxygenation and metabolism following high-altitude ICH.

    Iron overload plays a key role in the secondary brain damage that develops after intracerebral hemorrhage (ICH). The significant increase in iron deposition is associated with the generation of reactive oxygen species (ROS), which leads to oxidative brain damage. In this study, we examined the protective effects of VK-28, a brain-permeable iron chelator, against hemoglobin toxicity in an ex vivo organotypic hippocampal slice culture (OHSC) model and in middle-aged mice subjected to an in vivo, collagenase-induced ICH model. We found that the effects of VK-28 were similar to those of deferoxamine (DFX), a well-studied iron chelator. Both decreased cell death and ROS production in OHSCs and in vivo, decreased iron-deposition and microglial activation around hematoma in vivo, and improved neurologic function. Moreover, compared with DFX, VK-28 polarized microglia to an M2-like phenotype, reduced brain water content, deceased white matter injury, improved neurobehavioral performance, and reduced overall death rate after ICH. The protection of VK-28 was confirmed in a blood-injection ICH model and in aged-male and young female mice. Our findings indicate that VK-28 is protective against iron toxicity after ICH and that, at the dosage tested, it has better efficacy and less toxicity than DFX does.

    Oral infectious diseases are epidemiologically associated with stroke. We previously showed that oral Streptococcus mutans with the cnm gene encoding a collagen-binding Cnm protein induced intracerebral hemorrhage (ICH) experimentally and was also associated with cerebral microbleeds (CMBs) in our population-based cohort study. We therefore investigated the roles of cnm-positive Streptococcus mutans in this single hospital-based, observational study that enrolled 100 acute stroke subjects. The cnm gene in Streptococcus mutans isolated from saliva was screened using PCR techniques and its collagen-binding activities examined. CMBs were evaluated on T2* gradient-recalled echo MRI. One subject withdrew informed consent and 99 subjects (63 males) were analyzed, consisting of 67 subjects with ischemic stroke, 5 with transient ischemic attack, and 27 with ICH. Eleven cases showed Streptococcus mutans strains positive for cnm. The presence of cnm-positive Streptococcus mutans was significantly associated with ICH [OR vs. ischemic stroke, 4.5; 95% CI, 1.17-19.1] and increased number of deep CMBs [median (IQR), 3 (2-9) vs. 0 (0-1), p = 0.0002]. In subjects positive for Streptococcus mutans, collagen binding activity was positively correlated with the number of deep CMBs (R(2) = 0.405; p < 0.0001). These results provide further evidence for the key role of oral health in stroke.

    Full Text Available Intracerebral hemorrhage (ICH is an important public health problem with high rates of mortality, morbidity, and disability, but no clinically proven treatment strategy is available to date. Scalp acupuncture (SA refers to a therapy for treating diseases by needling and stimulating the specific areas of the scalp. The evidence from clinical studies suggested that SA therapy may produce significant benefits for patients with acute ICH. However, the therapeutic mechanisms are yet not well addressed. Therefore, in this paper, we provide a comprehensive overview on the history and mechanisms of SA therapy on acute ICH. Although SA has been practiced for thousands of years in China and could date back to 5 BC, SA therapy for acute ICH develops only in the recent 30 years. The possible mechanisms associated with the therapeutic effects of SA on ICH include the influence on hematoma, brain edema, and blood brain barrier, the products released from haematoma, the immune and inflammatory reaction, focal perihemorrhagic hypoperfusion and hemorheology, neuroelectrophysiology, and so on. At last, the existence of instant effect of SA on acute ICH and its possible mechanisms are presented.

    Early hematoma expansion in spontaneous intracerebral hemorrhage (ICH) is associated with worse clinical outcome. We hypothesized that hemodynamic parameters are associated with the increase in hematoma volume owing to their relationship to blood vessel wall stresses. We performed a post hoc analysis of clinical and computed tomography (CT) data from patients enrolled in a prospective observational study of ICH patients presenting within 3 hours from symptom onset. Hematoma volumes were measured at hospital arrival and at 1 and 20 hours from presentation. Blood pressure and heart rate, recorded at 19 time points between presentation and 20 hours, were used to derive hemodynamic variables. Multivariable logistic-regression models were constructed to assess the relation between hemodynamic parameters and hematoma growth, adjusted for clinical covariates. From the original study, 98 patients underwent baseline and 1-hour CT scans; of these, 65 had 20-hour CT scans. Substantial hematoma growth was observed in 28% within the first hour. Of the 65 patients not undergoing surgery within 20 hours, 37% experienced hematoma growth by 20 hours. Neither baseline or peak hemodynamic parameters nor changes in hemodynamic parameters were significantly associated with hematoma growth at either 1 or 20 hours. We found no blood pressure or heart rate parameters, individually or in combination, that were associated with hematoma growth. Our data suggest the influence of hemodynamic parameters on vessel wall stress to be an unlikely target for intervention in reducing the risk of early hematoma growth in ICH.

    TMS (transcranial magnetic stimulation) and DTT (diffusion tensor tractography) have different advantages in evaluating stroke patients. TMS has good clinical accessibility and economical benefit. On the contrary, DTT has a unique advantage to visualize neural tracts three-dimensionally although it requires an expensive and large MRI machine. Many studies have demonstrated that TMS and DTT have predictive values for motor outcome in stroke patients. However, there has been no study on the comparison of these two evaluation tools. In the current study, we compared the abilities of TMS and DTT to predict upper motor outcome in patients with ICH (intracerebral hemorrhage). Fifty-three consecutive patients with severe motor weakness were evaluated by TMS and DTT at the early stage (7-28 days) of ICH. Modified Brunnstrom classification (MBC) and the motricity index of upper extremity (UMI) were evaluated at onset and 6 months after onset. Patients with the presence of a motor evoked potential (MEP) in TMS or a preserved corticospinal tract (CST) in DTT showed better motor outcomes than those without (p=0.000). TMS showed higher positive predictive value than DTT. In contrast, DTT showed higher negative predictive value than TMS. TMS and DTT had different advantages in predicting motor outcome, and this result could be a reference to predict final neurological deficit at the early stage of ICH.

    Fisetin is commonly used as an anti-inflammatory and neuroprotective drug. In this study, we aimed to investigate the efficacy of fisetin in alleviating intracerebral hemorrhage (ICH)-induced brain injury. Mouse ICH models were constructed using the collagenase-induction method. ICH mice received fisetin treatment at the dose of 10-90 mg/kg, followed by the evaluation of neurological deficit through neurologic severity scores (mNSS), brain water content and terminal deoxynucleotidyl transferase dUTP nick end labeling analysis of cell apoptosis. Cytokine levels were also assessed with enzyme-linked immunosorbent assay. The activation of astrocytes and microglia was evaluated through S100 staining and Western blot analysis of ionized calcium-binding adaptor molecule 1 respectively. Nuclear factor kappa-B (NF-κB) signaling was also evaluated by Western blot. ICH mice demonstrated dramatic increase in mNSS, brain edema and cell apoptosis, indicating severe brain deficit. Fisetin treatment lowered these parameters, suggesting the alleviation of brain injury. Levels of proinflammatory cytokines were reduced, accompanied by a prominent decrease in activated astrocytes and microglia. NF-κB signaling was also attenuated by fisetin treatment. Fisetin effectively alleviates ICH by downregulating proinflammatory cytokines and attenuating NF-κB signaling. These data suggest fisetin as a valuable natural flavonol for clinical management of ICH-induced brain injury. © 2018 S. Karger AG, Basel.

    Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24 h after symptom onset, but predominantly occurs in the early hours. Thus capturing markers of on-going bleeding on imaging techniques could predict hematoma expansion. The spot sign observed on computed tomography angiography is believed to represent on-going bleeding and is to date the most well investigated and reliable radiological predictor of hematoma expansion as well as functional outcome and mortality. On non-contrast CT, the presence of foci of hypoattenuation within the hematoma along with the hematoma-size is reported to be predictive of hematoma expansion and outcome. Because patients tend to arrive earlier to the hospital, a larger fraction of acute ICH-patients must be expected to undergo hematoma expansion. This renders observation and radiological follow-up investigations increasingly relevant. Transcranial duplex sonography has in recent years proven to be able to estimate hematoma volume with good precision and could be a valuable tool in bedside serial observation of acute ICH-patients. Future studies will elucidate, if better prediction and observation of post-admission hematoma expansion can help select patients, who will benefit from hemostatic treatment. PMID:25324825

    Intracerebral hemorrhage (ICH) is a devastating cerebrovascular disorder with high morbidity and mortality. Minocycline is a matrix metalloproteinase-9 (MMP-9) inhibitor that may attenuate secondary mechanisms of injury in ICH. The feasibility and safety of minocycline in ICH patients were evaluated in a pilot, double-blinded, placebo-controlled randomized clinical trial. Patients with acute onset (minocycline or placebo. The outcome events included adverse events, change in serial National Institutes of Health Stroke Scale score assessments, hematoma volume and MMP-9 measurements, 3-month functional outcome (modified Rankin score) and mortality. A total of 20 patients were randomized to minocycline (n = 10) or placebo (n = 10). The two groups did not differ in terms of baseline characteristics. No serious adverse events or complications were noted with minocycline infusion. The two groups did not differ in any of the clinical and radiological outcomes. Day 5 serum MMP-9 levels tended to be lower in the minocycline group (372 ± 216 ng/ml vs. 472 ± 235 ng/ml; P = 0.052). Multiple linear regression analysis showed that minocycline was associated with a 217.65 (95% confidence interval -425.21 to -10.10, P = 0.041) decrease in MMP-9 levels between days 1 and 5. High-dose intravenous minocycline can be safely administered to patients with ICH. Larger randomized clinical trials evaluating the efficacy of minocycline and MMP-9 inhibition in ICH patients are required. © 2017 EAN.

    Intracerebral hemorrhage is the least treatable type of stroke and affects millions of people worldwide. Treatment for ICH varies from medicine to surgery, but the rate of mortality and mobility still remains high. Minocycline is a tetracycline antibiotic increasingly recognized for its neuroprotective potential. In earlier studies, we demonstrated that many secondary injuries caused by ICH could be significantly reduced by injection of minocycline in rat models. The following research investigates the role of minocycline in reducing brain injury. Twenty-four rats were administered 100μl autologous arterial blood injections into the right basal ganglia, treated with minocycline or vehicle and euthanized on the 1st, 3rd, and 7th day. Immunohistochemistry, TUNEL, and western blot analysis were performed to analyze the effects of minocycline on apoptosis and autophagy. After the injection of minocycline, TUNEL-positive cells were remarkably reduced on days 1, 3 and 7; Beclin-1, LC3BII/I, caspase-3/8 were all suppressed after treatment. The relationship between Cathepsin D and minocycline remained unknown. Our studies suggest the potential medicinal value of minocycline, through both anti-autophagy and anti-apoptosis pathways.

    Spontaneous intracerebral hemorrhage (ICH) is one of the most devastating types of stroke. Here, we aim to demonstrate that electroacupuncture on Baihui (GV20) exerts neuroprotection for acute ICH possibly via the caveolin-1/matrix metalloproteinase/blood-brain barrier permeability pathway. The model of ICH was established by using collagenase VII. Rats were randomly divided into three groups: Sham-operation group, Sham electroacupuncture group, and electroacupuncture group. Each group was further divided into 4 subgroups according to the time points of 6 h, 1 d, 3 d, and 7 d after ICH. The methods were used including examination of neurological deficit scores according to Longa's scale, measurement of blood-brain barrier permeability through Evans Blue content, in situ immunofluorescent detection of caveolin-1 in brains, western blot analysis of caveolin-1 in brains, and in situ zymography for measuring matrix metalloproteinase-2/9 activity in brains. Compared with Sham electroacupuncture group, electroacupuncture group has resulted in a significant improvement in neurological deficit scores and in a reduction in Evans Blue content, expression of caveolin-1, and activity of matrix metalloproteinase-2/9 at 6 h, 1 d, 3 d, and 7 d after ICH ( P electroacupuncture on GV20 can improve neurological deficit scores and reduce blood-brain barrier permeability after ICH, and the mechanism possibly targets caveolin-1/matrix metalloproteinase/blood-brain barrier permeability pathway.

    Full Text Available Aim. Investigation of the extent of morphological changes and activity of biogenic amines (according to the intensity of luminescence in the neurons of the brain stem in intracerebral hemorrhage (ICH. Methods and results. ICH was designed on 29 white rats of Vistar line by the administration of autologous blood in the cerebral hemisphere. It was revealed that increased luminescence intensity by 18.4±5.5% was registered in monoaminergic neurons in 1–6 hours after experimental ICH. After 12 hours – 1 day development of dislocation syndrome leads to mosaic focal ischemic neuronal injuries with maximum reduction in the level of catecholamines by 29.5±5.0% compared with control cases. Three–6 days after ICH on a background of selective neuronal necrosis in substantial number of neurons in the nuclei of the brainstem the level of catecholamines is significantly reduced. Conclusion. Disclosed observations reflect significant functional pathology of neurons responsible for the regulation of cardiorespiratory function and may underlie disturbances of integrative activity in the brain stem in general.

    In traumatic brain injury (TBI) and intracerebral hemorrhage (ICH), the heterogeneity of lesion sizes and types necessitates a variety of imaging modalities to acquire a comprehensive perspective on injury extent. Although it is advantageous to combine imaging modalities and to leverage their complementary benefits, there are difficulties in integrating information across imaging types. Thus, it is important that efforts be dedicated to the creation and sustained refinement of resources for multimodal data integration. Here, we propose a novel approach to the integration of neuroimaging data acquired from human patients with TBI/ICH using various modalities; we also demonstrate the integrated use of multimodal magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) data for TBI analysis based on both visual observations and quantitative metrics. 3D models of healthy-appearing tissues and TBIrelated pathology are generated, both of which are derived from multimodal imaging data. MRI volumes acquired using FLAIR, SWI, and T2 GRE are used to segment pathology. Healthy tissues are segmented using user-supervised tools, and results are visualized using a novel graphical approach called a `connectogram', where brain connectivity information is depicted within a circle of radially aligned elements. Inter-region connectivity and its strength are represented by links of variable opacities drawn between regions, where opacity reflects the percentage longitudinal change in brain connectivity density. Our method for integrating, analyzing and visualizing structural brain changes due to TBI and ICH can promote knowledge extraction and enhance the understanding of mechanisms underlying recovery.

    Full Text Available Gender differences are well described for patients with ischemic stroke. Conversely, sex disparities in stroke presentation, risk factors, treatment, and outcomes for intracerebral hemorrhage (ICH were not previously studied. Our objective was to compare the frequency of risk factors, management patterns, symptoms at presentation, complication rates, and outcomes between genders in patients with ICH in Fortaleza, Brazil. Methods: Data were prospectively collected from patients admitted to 19 hospitals in Fortaleza with a diagnosis of ICH by trained research coordinators from June 2009 to October 2010. Daily visits to the selected hospitals were performed, and all patients admitted with a diagnosis of ICH were prospectively evaluated. Results: We evaluated 364 patients, 47.5% of whom were women. Men were younger (59.3 ± 14.58 years vs. 66.3 ± 14.6 years, p Conclusion: Overall risk factors for ICH in men and women were similar in our series. Men had a higher frequency of alcohol abuse and smoking. Women were older, had an increased time length from symptoms onset to hospital admission and had a worse prognosis at discharge. A better understanding of the gender disparities in patients with ICH will hopefully lead to better outcomes in both sexes in the future.

    Background. Cerebral microbleeds (CMBs) detected by gradient-echo MRI have been proven to be a potential risk factor for further bleeding, while the association between CMBs and the first onset of intracerebral hemorrhage has not been well investigated. Purpose. To analyze the association between CMBs and the first onset of primary intracerebral hemorrhage (pICH). Material and Methods. Two hundred and two consecutive inpatients with ICH and 234 consecutive outpatients without ICH as control group were enrolled in this study. MR imaging including T2*-GRE, T 1 W, T 2 W and fluid attenuated inversion recovery (FLAIR) sequences were performed to detect CMBs and other abnormalities. Prevalence, distribution, and grades of CMBs, as well as the location and size of the intracerebral hematoma were analyzed, respectively. Comparison was made between pICH and control group. Logistic analysis was performed to evaluate the association between CMBs and ICH. The correlation between hematoma size and CMBs grade/numbers was analyzed. Results. CMBs were detected in 140 patients in pICH (69.3%) group and 62 patients in control group (26.5%). The incidence of CMBs in pICH group was significantly higher than that in control group (P < 0.0001). As the logistic regression analysis results, CMBs was the risk factor associated with ICH, with modulation OR value of 8.363 (95% CI 5.210-13.421). The volume of ICH with CMBs was 12.57 ± 17.23 mL, and the volume of ICH without CMBs was 17.77 ± 26.97 mL. Negative correlation was demonstrated between CMBs number and ICH volume (rs = -0.1769, P = 0.0118), as well as between CMBs grade and hematoma volume (rs = -0.1185, P = 0.1557). Conclusion CMBs may be an independent risk factor for the first onset of intracerebral hemorrhage

    The purpose of our study was to determine the frequency and severity of intracerebral hemorrhages and T2 hyperintense white matter lesions (WMLs) following radiation therapy for brain tumors in adult patients. Of 648 adult brain tumor patients who received radiation therapy at our institute, magnetic resonance (MR) image data consisting of a gradient echo (GRE) and FLAIR T2-weighted image were available three and five years after radiation therapy in 81 patients. Intracerebral hemorrhage was defined as a hypointense dot lesion appearing on GRE images after radiation therapy. The number and size of the lesions were evaluated. The T2 hyperintense WMLs observed on the FLAIR sequences were graded according to the extent of the lesion. Intracerebral hemorrhage was detected in 21 (25.9%) and 35 (43.2) patients in the three- and five-year follow-up images, respectively. The number of intracerebral hemorrhages per patient tended to increase as the follow-up period increased, whereas the size of the intracerebral hemorrhages exhibited little variation over the course of follow-up. T2 hyperintense WMLs were observed in 27 (33.3%) and 32 (39.5) patients in the three and five year follow-up images, respectively. The age at the time of radiation therapy was significantly higher (p T2 hyperintense WMLs than in those without lesions. Intracerebral hemorrhages are not uncommon in adult brain tumor patients undergoing radiation therapy. The incidence and number of intracerebral hemorrhages increased over the course of follow-up. T2 hyperintense WMLs were observed in more than one-third of the study population.

    Full Text Available Neuro-inflammation plays an important role in the recovery of brain injury after stroke. Microglia/macrophage is the major executor in the neuro-inflammation, which can be polarized into two distinct phenotypes: injurious/toxic classical activation (M1 phenotype and protective alternative activation (M2 phenotype. Here, we investigated whether intracerebral administration of interleukin-4 (IL-4 at an early stage could affect the activation of microglia/macrophage and the corresponding outcome after intracerebral hemorrhage (ICH. The neuro-behavior was recorded between different groups in the rat ICH model. The M1 and M2 markers were then determined by qRT-PCR, western blotting, ELISA and immunofluorescence, respectively. We observed aberrant activation of microglia/macrophage after ICH. After intracerebral injection of IL-4, M1 activation was greatly inhibited while M2 activation was enhanced, along with improving neurobehavioral recovery from deficits after ICH. Our study showed that early intracerebral injection of IL-4 potentially promotes neuro-functional recovery, probably through enhancing the alternative activation of microglia/macrophage.

    We review the signal characteristics of intracerebral hematomas (ICH) on magnetic resonance imaging (MRI), with special emphasis on the diagnosis of intracerebral hemorrhage within the first hours after stroke. The detection of peracute ICH was evaluated in 42 patients of a prospective, MR randomized stroke trial. These patients underwent a protocol of T1 and T2 weighted sequences, diffusion weighted sequences and MR - angiography within 6 hours after onset of acute hemiparesis. The signal behaviour of ICH in any stage after bleeding was additionally reviewed in a retrospective series of 63 patients, who were submitted for MRI over a 12 months period because of known ICH. MRI correctly identified 4 hyperacute ICH in the prospective group and 4 hyperacute ICH in the retrospective group. These ICHs had high signal on T2 weighted images, were isointense in T1 weighted images and had signal voids on the diffusion weighted sequences. The signal intensities of acute, subacute and chronic ICHs correlated to previous experiences as reported in the literature. In conclusion, MRI reliably identified all hematomas even in the hyperacute stage. Diffusion weighted images were most sensitive to the presence of deoxyhemoglobine and helpful for the differentiation and characterization of acute ischemia. Therefore, MRI at 1.5 T can be employed as an alternative to CT for the emergency diagnosis of acute stroke. (orig.)

    Bromadiolone, often called a super-warfarin, is a potent rodenticide with long half-life. Skin and mucosal bleeding is the most common clinical manifestations of its intoxication. Bromadiolone intoxications in adults and children have been reported, but this phenomenon is rarely seen in fetuses. This paper presents a case of neonate with massive intracranial hemorrhage mediated by bromadiolone intoxication, highlighting that the bromadiolone is potentially lethal to the fetus. The male neonate presented with poor respiratory effort, decreased muscle tone, and pallor at birth. He developed generalized seizures on day 1 of life. His mother suffered from bleeding of oral mucosa and the subsequent lab screening for toxicants showed a bromadiolone level of 126 ng/mL. Laboratory tests revealed that prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT). A computed tomography (CT) of his head revealed a severe subdural hematoma, which lead to midline shift, bilateral intraventricular hemorrhage, and subarachnoid hemorrhage. Serum from cord blood was collected and screened for toxicants. The result returned with a bromadiolone level of 94 ng/mL. The neonate was treated with vitamin K, fresh-frozen plasma, and red blood cells. His parents required termination of all treatments, and the neonate unfortunately died shortly after. Through clinical experience from this case, we believe that bromadiolone can be passed down to the fetus via placenta. Neonatal intracranial hemorrhage caused by bromadiolone is rare but potentially lethal. Pregnant women should be informed of the serious side effects of bromadiolone and this poisonous reagent should be avoided in any period during pregnancy.

    Hematoma expansion is related to poor outcome in spontaneous intracerebral hemorrhage (ICH). Recently, a non-enhanced computed tomography (CT) based finding, termed the 'satellite sign', was reported to be a novel predictor for poor outcome in spontaneous ICH. However, it is still unclear whether the presence of the satellite sign is related to hematoma expansion. Initial computed tomography angiography (CTA) was conducted within 6h after ictus. Satellite sign on non-enhanced CT and spot sign on CTA were detected by two independent reviewers. The sensitivity and specificity of both satellite sign and spot sign were calculated. Receiver-operator analysis was conducted to evaluate their predictive accuracy for hematoma expansion. This study included 153 patients. Satellite sign was detected in 58 (37.91%) patients and spot sign was detected in 38 (24.84%) patients. Among 37 patients with hematoma expansion, 22 (59.46%) had satellite sign and 23 (62.16%) had spot sign. The sensitivity and specificity of satellite sign for prediction of hematoma expansion were 59.46% and 68.97%, respectively. The sensitivity and specificity of spot sign were 62.16% and 87.07%, respectively. The area under the curve (AUC) of satellite sign was 0.642 and the AUC of spot sign was 0.746. (P=0.157) CONCLUSION: Our results suggest that the satellite sign is an independent predictor for hematoma expansion in spontaneous ICH. Although spot sign has the higher predictive accuracy, satellite sign is still an acceptable predictor for hematoma expansion when CTA is unavailable. Copyright © 2017 Elsevier B.V.

    To determine whether the CT angiography (CTA) spot sign marks bleeding complications during and after surgery for spontaneous intracerebral hemorrhage (ICH). In a 2-center study of consecutive spontaneous ICH patients who underwent CTA followed by surgical hematoma evacuation, 2 experienced readers (blinded to clinical and surgical data) reviewed CTAs for spot sign presence. Blinded raters assessed active intraoperative and postoperative bleeding. The association between spot sign and active intraoperative bleeding, postoperative rebleeding, and residual ICH volumes was evaluated using univariable and multivariable logistic regression. A total of 95 patients met inclusion criteria: 44 lobar, 17 deep, 33 cerebellar, and 1 brainstem ICH; ≥1 spot sign was identified in 32 patients (34%). The spot sign was the only independent marker of active bleeding during surgery (odds ratio [OR] 3.4; 95% confidence interval [CI] 1.3-9.0). Spot sign (OR 4.1; 95% CI 1.1-17), female sex (OR 6.9; 95% CI 1.7-37), and antiplatelet use (OR 4.6; 95% CI 1.2-21) were predictive of postoperative rebleeding. Larger residual hematomas and postoperative rebleeding were associated with higher discharge case fatality (OR 3.4; 95% CI 1.1-11) and a trend toward increased case fatality at 3 months (OR 2.9; 95% CI 0.9-8.8). The CTA spot sign is associated with more intraoperative bleeding, more postoperative rebleeding, and larger residual ICH volumes in patients undergoing hematoma evacuation for spontaneous ICH. The spot sign may therefore be useful to select patients for future surgical trials. © 2014 American Academy of Neurology.

    To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. Supratentorial sICH patients receiving hematoma evacuation within 24 hours after ictus were enrolled in this study. uHG was defined as baseline hematoma volume/onset-to-computed tomography (CT) time (mL/h). The outcome was assessed by the modified Rankin Scale (mRS) score at 3 months. Unfavorable outcome was defined as mRS >2. A total of 93 patients were enrolled in this study. The mean uHG was 10.3 ± 5.5 mL/h. In 69 (74.2%) of patients, the outcome was unfavorable at 3 months. The uHG in patients with unfavorable outcome were significantly higher than in those with favorable outcome (11.0 ± 6.1 mL/h vs. 8.3 ± 2.5 mL/h, P = 0.003). The optimal cutoff of uHG for predicting unfavorable outcome was 8.7 mL/h. The sensitivity, specificity, positive predictive value, and negative predictive value of uHG >8.7 mL/h for predicting unfavorable outcome were 56.5%, 75.0%, 86.7%, and 37.5%, respectively. uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h. Copyright © 2017 Elsevier Inc. All rights reserved.

    Oxidative injury caused by reactive oxygen species plays an important role in the progression of intracerebral hemorrhage (ICH)-induced secondary brain injury. Previous studies have demonstrated that the free radical scavenger edaravone may prevent neuronal injury and brain edema after ICH. However, the influence of edaravone on cerebral metabolism in the early stages after ICH and the underlying mechanism have not been fully investigated. In the present study, we investigated the effect of edaravone on perihematomal glucose metabolism using (18)F-fluorordeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). Additionally, the neurologic deficits, brain edemas, and cell death that followed ICH were quantitatively analyzed. After blood infusion, the rats treated with edaravone showed significant improvement in both forelimb placing and corner turn tests compared with those treated with vehicle. Moreover, the brain water content of the edaravone-treated group was significantly decreased compared with that of the vehicle group on day 3 after ICH. PET/CT images of ICH rats exhibited obvious decreases in FDG standardized uptake values in perihematomal region on day 3, and the lesion-to-normal ratio of the edaravone-treated ICH rats was significantly increased compared with that of the control rats. Calculation of the brain injury volumes from the PET/CT images revealed that the volumes of the blood-induced injuries were significantly smaller in the edaravone group compared with the vehicle group. Terminal Deoxynucleotidyl Transferase-mediated dUTP Nick End Labeling assays performed 3 days after ICH revealed that the numbers of apoptotic cells in perihematomal region of edaravone-treated ICH rats were decreased relative to the vehicle group. Thus, the present study demonstrates that edaravone has scavenging properties that attenuate neurologic behavioral deficits and brain edema in the early period of ICH. Additionally, edaravone may improve

    Full Text Available A number of studies have reported an association of angiotensin-converting enzyme (ACE gene polymorphism with primary intracerebral hemorrhage (PICH, however the reports have demonstrated inconclusive results. To clarify this conflict, we updated the previously performed meta-analysis by Peck et al., which revealed negative results, by investigating the ACE polymorphism and its correlation to PICH.PubMed and Embase databases (through Dec 2012 were searched for English articles on the relationship of the I/D polymorphism in ACE with PICH in humans. Summary odds ratios (ORs were estimated and potential sources of heterogeneity and bias were explored.A total of 805 PICH cases and 1641 control cases obtained from 8 case-control studies were included. The results suggest that in dominant genetic models, the ACE I/D polymorphic variant was associated with a 58% increase in susceptibility risk of PICH (OR = 1.58; 95% CI = 1.07-2.35 for DD vs. DI+II. However, in the subgroup analysis based on race, a significant increased risk was found in Asian DD homozygote carriers (OR = 1.76 and 95% CI = 1.16-2.66 for DD vs. DI+II, but not in Caucasian DD homozygote carriers (OR = 1.18, 95% CI = 0.36-3.88, P = 0.784 for DD vs. DI+II. The heterogeneity between studies was remarkable, and its major sources of heterogeneity were due to the year in which the study was published. No potential publication bias was observed in dominant genetic models.These data demonstrated evidence of a positive association between ACE I/D polymorphism with PICH, and suggested that the ACE gene is a PICH susceptible gene in Asian populations.

    Intracerebral hemorrhage (ICH) is a particularly devastating form of stroke with high mortality and morbidity. Hematomas are the primary cause of neurologic deficits associated with ICH. The products of hematoma are recognized as neurotoxins and the main contributors to edema formation and tissue damage after ICH. Finding a means to efficiently promote absorption of hematoma is a novel clinical challenge for ICH. Peroxisome proliferator-activated receptor gamma (PPARγ) and nuclear factor erythroid 2-related factor 2 (Nrf2), had been shown that, can take potential roles in the endogenous hematoma clearance. However, monascin, a novel natural Nrf2 activator with PPARγ agonist, has not been reported to play a role in ICH. This study was designed to evaluate the effect of monascin on neurological deficits, hematoma clearance and edema extinction in a model of ICH in rats. 164 adult male Sprague-Dawley (SD) rats were randomly divided into sham; vehicle; monascin groups with low dosages (1mg/kg/day), middle dosages (5mg/kg/day) and high dosages (10mg/kg/day) respectively. Animals were euthanized at 1, 3 and 7days following neurological evaluation after surgery. We examined the effect of monascin on the brain water contents, blood brain barrier (BBB) permeability and hemoglobin levels, meanwhile reassessed the volume of hematoma and edema around the hematoma by Magnetic Resonance Imaging (MRI) in each group. The high dosage of monascin significantly improved neurological deficits, reduced the volume of hematoma in 1-7days after ICH, decreased BBB permeability and edema formation in 1-3days following ICH. Our study demonstrated that the high dosage of monascin played a neuroprotective role in ICH through reducing BBB permeability, edema and hematoma volume. Copyright © 2017 Elsevier Inc.

    Full Text Available We sought to summarize Computed Tomography (CT/Magnetic Resonance Imaging (MRI features of intracerebral hemorrhage (ICH associated with cerebral amyloid angiopathy (CAA in published observational radio-pathological studies.In November 2016, two authors searched OVID Medline (1946-, Embase (1974- and relevant bibliographies for studies of imaging features of lobar or cerebellar ICH with pathologically proven CAA ("CAA-associated ICH". Two authors assessed studies' diagnostic test accuracy methodology and independently extracted data.We identified 22 studies (21 cases series and one cross-sectional study with controls of CT features in 297 adults, two cross-sectional studies of MRI features in 81 adults and one study which reported both CT and MRI features in 22 adults. Methods of CAA assessment varied, and rating of imaging features was not masked to pathology. The most frequently reported CT features of CAA-associated ICH in 21 case series were: subarachnoid extension (pooled proportion 82%, 95% CI 69-93%, I2 = 51%, 12 studies and an irregular ICH border (64%, 95% CI 32-91%, I2 = 85%, five studies. CAA-associated ICH was more likely to be multiple on CT than non-CAA ICH in one cross-sectional study (CAA-associated ICH 7/41 vs. non-CAA ICH 0/42; χ2 = 7.8, p = 0.005. Superficial siderosis on MRI was present in 52% of CAA-associated ICH (95% CI 39-65%, I2 = 35%, 3 studies.Subarachnoid extension and an irregular ICH border are common imaging features of CAA-associated ICH, but methodologically rigorous diagnostic test accuracy studies are required to determine the sensitivity and specificity of these features.

    Full Text Available Background: The outcome of patients with spontaneous supratentorial intracerebral hemorrhage (SSICH is unsatisfactory. Inflammatory response secondary to brain injury as well as those resulted from surgical procedure were considered responsible of this outcome. This study was intended to elucidate the anti-inflammatory activity of tigecycline by measuring TNF-α level and its neuroprotective effect as represented by inhospital mortality rate.Methods: Patients with SSICH who were prepared for hematoma evacuation were randomized to receive either tigecycline (n=35 or fosfomycine (n=37 as prophylactic antibiotic. TNF-α level was measured in all subjects before surgery and postoperatively on day-1 and day-7. A repeated brain CT Scan was performed on postoperative day-7. The Glasgow outcome scale (GOS and length of stay (LOS were recorded at the time of hospital discharge. Data were analyzed using Mann-Whitney and Chi square test. Relative clinical effectiveness was measured by calculating the number needed to treat (NNT.Results: There was a significant difference regarding the proportion of subject who had  reduced TNF-α level on postoperative day-7 between the groups receiving tigecycline and fosfomycine (62% vs 29%, p=0.022. Decrease brain edema on CT control (86% vs 80%, p=0.580. Tigecycline administration showed a tendency of better clinical effectiveness in lowering inhospital mortality (17% vs 35%; p=0.083; OR=0.49; NNT=5 and worse clinical outcome / GOS ≤ 2 (20% vs 38% ; p=0.096; OR=0.41; NNT=6. LOS ≥ 15 hari ( 40% vs 27%; p=0.243; OR=1.81; NNT=8.Conclusion: Tigecycline showed anti-inflammatory and neuroprotective activities. These activities were associated with improved clinical outcome in patients with SSICH after hematoma evacuation.

    Full Text Available Spontaneous intracerebral hemorrhage (ICH is one of the most devastating types of stroke. Here, we aim to demonstrate that electroacupuncture on Baihui (GV20 exerts neuroprotection for acute ICH possibly via the caveolin-1/matrix metalloproteinase/blood-brain barrier permeability pathway. The model of ICH was established by using collagenase VII. Rats were randomly divided into three groups: Sham-operation group, Sham electroacupuncture group, and electroacupuncture group. Each group was further divided into 4 subgroups according to the time points of 6 h, 1 d, 3 d, and 7 d after ICH. The methods were used including examination of neurological deficit scores according to Longa’s scale, measurement of blood-brain barrier permeability through Evans Blue content, in situ immunofluorescent detection of caveolin-1 in brains, western blot analysis of caveolin-1 in brains, and in situ zymography for measuring matrix metalloproteinase-2/9 activity in brains. Compared with Sham electroacupuncture group, electroacupuncture group has resulted in a significant improvement in neurological deficit scores and in a reduction in Evans Blue content, expression of caveolin-1, and activity of matrix metalloproteinase-2/9 at 6 h, 1 d, 3 d, and 7 d after ICH (P<0.05. In conclusion, the present results suggested that electroacupuncture on GV20 can improve neurological deficit scores and reduce blood-brain barrier permeability after ICH, and the mechanism possibly targets caveolin-1/matrix metalloproteinase/blood-brain barrier permeability pathway.

    Background and Purpose This study aimed to explore the relationship between blend sign and prognosis of patients with intracerebral hemorrhage (ICH). Methods Between January 2014 and December 2016, the results of cranial computed tomography imaging within 24 h after the onset of symptoms from 275 patients with ICH were retrospectively analyzed. The patients with or without blend sign were compared to observe and analyze the difference in coagulation function abnormality, rebleeding, mortality, and bad prognosis rates in the early stages. Results Of the 275 patients with ICH, 47 patients had Blend Sign I (17.09%) and 17 patients had Blend Sign II (6.18%). The coagulation function abnormality rate had no statistical difference among Blend Sign I, Blend Sign II, and conventional groups (P > 0.05). In the Blend Sign I group, the rebleeding rate was 4.26%, bad prognosis rate was 25.53%, and mortality rate was 6.38%, which were not statistically significantly different compared with those in the conventional group (P > 0.05). The rebleeding rate in the Blend Sign II group was 47.06%, bad prognosis rate was 82.35%, and mortality rate was 47.06%, which were statistically significantly different compared with those in the conventional and Blend Sign I groups (P Blend Sign I, the prognosis was equivalent to that in the conventional group, with no statistically significant difference. The rebleeding, bad prognosis, and mortality rates were higher in the Blend Sign II group than in the conventional group and deserved more attention.

    Attained height, an indicator of genetic potential and childhood growth environment, is inversely associated with stroke, but the mechanisms are poorly understood. We investigated whether childhood height and growth are associated with ischemic stroke (IS) and intracerebral hemorrhage (ICH). In a cohort of Danish schoolchildren born 1930 to 1989, with measured height from 7 to 13 years, we investigated associations of childhood stature and growth with risks of adult IS and ICH. Cox proportional hazards regressions were performed to estimate hazard ratios (HRs) with CIs separately for women and men. Among 311 009 individuals, 10 412 were diagnosed with IS and 2546 with ICH. Height at 7 years was inversely and significantly associated with IS in both sexes (per z score, equivalent to ≈5.2 cm in women and 5.1 cm in men; women: HR=0.89 [95% CI: 0.87-0.92]; men: HR=0.90 [95% CI: 0.88-0.92]) and with ICH in men (HR=0.89 [95% CI: 0.84-0.94]) but not in women (HR=0.97 [95% CI: 0.91-1.04]). Associations were similar at older childhood ages and were stable throughout the study period. No statistically significant associations for growth from 7 to 13 years were observed for IS or ICH. Short stature at 7 to 13 years is significantly associated with increased risks of IS in both sexes and with ICH in men. Growth during this period of childhood is not significantly associated with either of these stroke subtypes, suggesting that underlying mechanisms linking height with risks of stroke may exert their influence already by early childhood. © 2018 American Heart Association, Inc.

    Intracerebral hemorrhages (ICHs) occur in 24 out of 100,000 people annually and have high morbidity and mortality rates. The standard treatment is conservative. We hypothesize that a patient-specific, mechanical model coupled with a robotic steerable needle, used to aspirate a hematoma, would result in a minimally invasive approach to ICH management that will improve outcomes. As a preliminary study, three realizations of a tissue aspiration framework are explored within the context of a biphasic finite element model based on Biot's consolidation theory. Short-term transient effects were neglected in favor of steady state formulation. The Galerkin Method of Weighted Residuals was used to solve coupled partial differential equations using linear basis functions, and assumptions of plane strain and homogeneous isotropic properties. All aspiration models began with the application of aspiration pressure sink(s), calculated pressures and displacements, and the use of von Mises stresses within a tissue failure criterion. With respect to aspiration strategies, one model employs an element-deletion strategy followed by aspiration redeployment on the remaining grid, while the other approaches use principles of superposition on a fixed grid. While the element-deletion approach had some intuitive appeal, without incorporating a dynamic grid strategy, it evolved into a less realistic result. The superposition strategy overcame this, but would require empirical investigations to determine the optimum distribution of aspiration sinks to match material removal. While each modeling framework demonstrated some promise, the superposition method's ease of computation, ability to incorporate the surgical plan, and better similarity to existing empirical observational data, makes it favorable.

    Two cases of intractable temporal lobe epilepsy associated with old intracerebral hemorrhage in the lateral temporal lobe were reported. Although preoperative magnetic resonance imaging (MRI) failed to reveal hippocampal atrophy with T2 hyperintensity, electrocorticographic (ECoG) recording with chronic invasive subdural electrodes indicated the mesial temporal lobe to be an ictal onset zone. After anterior temporal lobectomy involving the lesion and hippocampectomy, the patients became seizure-free. Hippocampal sclerosis, namely "dual pathology", was not noted on histological examination. Careful ECoG recording with chronic subdural electrodes is mandatory even when the preoperative MRI does not demonstrate the radiological hippocampal sclerosis.

    Objective: To investigate the effect of edaravone treatment on plasma ET-1 and CGRP levels changes in patients with traumatic intracerebral hemorrhage. Methods: Plasma ET-1 and CGRP levels were measured with RIA in 40 patients with traumatic intracerebral hemorrhage both before and after treatment with 60mg of edaravone i. v. q. d. for 5 days, 40 patients both before and after treatment with conventional treatment only (without edaravone) and 30 controls (once only). Results: The plasma ET-1 levels were significantly increased in all the patients at admission than those in controls. After treatment, the levels in all the patients dropped significantly, but the levels were significantly lower in edaravone-treated patients than those in non-edaravone-treated patients (P<0.01). The reverse was true for plasma CGRP levels. Conclusion: Edaravone treatment could correct the abnormal plasma ET-1 and CGRP levels in patients with traumatic intracerebral hemorrhage and might be beneficial to recovery. (authors)

    Full Text Available Background: Primary multiple simultaneous intracerebral hemorrhages (MSICHs are quite rare. Although occasional reports have been found, there have been no systematic reviews. The published case reports and case series contain overlapping data, leading to erroneous information about MSICHs. This is the first extensive review of accessible studies published in English on MSICHs. Our primary objective was to analyze the demographic data on age, sex, outcome and prognosis with regard to primary MSICHs. Summary: A PubMed search without language restriction for articles with results from human studies and registered between January 1950 and September 2013 yielded 677 articles. The following inclusion criteria were applied: (1 reported case(s or case series on primary MSICHs; (2 text partly or fully in English, and (3 text contains identifiable data on age, sex and outcome of patients. A total of 24 articles met all the inclusion criteria. The reference lists of these 24 articles were inspected for additional relevant articles, which yielded another 20 articles.

    Full Text Available Background and Purposes: Stroke is still one of a leading health-care problem in industrial country and in the developing country. Spontaneous Intra-cerebral Hemorrhage accounts for 30–60% of all stroke admissions into a hospital. Presence of intra-cerebral hemorrhage is considered a poor prognostic factor due to the resultant obstruction to the mass effect following the presence of blood resulting in raised intracranial pressure. While the craniotomy procedure failed to show more benefits over functional outcome, a less invasive and quicker surgical decompression might improve the outcome. Neuroendoscopy is one of promising optional  on minimal invasive  treatment  for spontaneous intra-cerebral hemorrhage. Material and Methods: We evaluated Glasgow Outcome Score and clinical outcome of patients with Spontaneous Intra-cerebral Hemorrhage who underwent modified neuroendoscopic surgery and craniotomy. Randomized control trial was performed during 27 months in 43 patients. Twenty-five patients treated with neuroendoscopy surgery and 18 patients with craniotomy. The removal of intra-cerebral hemorrhage was done by a modified neuroendoscopic transparent sheath made of silastic material, derived from pieces of thoracic tube No. 21F as a conduit working channel. Results: We analyzed statistically, clinical outcome assessment and Glasgow Outcome Scale 6 months post operative follow-up period. The mortality rate was significantly higher by Pearson chi-square methods, in craniotomy group n=12 (63.2% compared with neuroendoscopy group, n=7 (36.8% (p<.005. Patients with Glasgow Outcome Scale score 3–5 was higher in neuroendoscopy group, n=18 (75% compared with craniotomy group n=6 (25%. The survival rate analyzed by Kaplan Meier methods, found that patients in the neuroendoscopy group were a significantly longer survival rate compare with the craniotomy group during 6 months post operative follow-up period.

    Animal models of intracerebral hemorrhage were established by injection of autologous blood into the caudate nucleus in rats. Cell apoptosis was measured by flow cytometry and immunohistochemical staining of the p75 neurotrophin receptor. p75 neurotrophin receptor protein was detected by immunohistochemistry. p75 neurotrophin receptor mRNA was examined by quantitative real-time polymerase chain reactions. At 24 hours after modeling, cellular apoptosis occured around hematoma with upregulation of p75 neurotrophin receptor protein and mRNA was observed, which directly correlated to apoptosis. This observation indicated that p75 neurotrophin receptor upregulation was associated with cell apoptosis around hematomas after intracerebral hemorrhage.

    Full Text Available This is a presentation of Wegener Granulomatosis (WG disease. Even though the lungs are rarely affected. massive alveolar hemorrhage is seen which leads to mortality. The patient was a 28 year old man. His illness was diagnosed as WG and glomerulonephritis a year previously and he was treated by administration of methylprednisolone orally. He had been treated irregularly. He applied to the emergency service with hemoptysis and asthma complaints two days earlier. After the results of his examination Hb: 3.6 gr/dl, Htc:10.3%, Üre:131 mg /dl, kreatini: 7.7 mg/dl, pH: 7.41, pO2: 55 mmHg, pCO2:33 mmHg, and being diagnosed as alveolar consolidation on lung X-ray, he was taken to the intensive care unit with a diagnosis of a massive alveolar hemorrhagei. He was intubated and attached to mechanical ventilation. He was treated with parenteral 1 mg/kg/day methylprednisolone and, siklofosfamid 2 mg/kg/day. He was extubated on the 21st day. He was taken to the chest service department on 24th day. He is still being treated.

    Full Text Available Background: There is paucity of methodologically sound published studies on intracerebral hemorrhage (ICH from India, on pub med/embase search. Aims: To explore etiology of ICH and correlate the causes, location, and size of hemorrhage to clinical outcome. Materials and Methods: A hospital-based descriptive study from South Indian eastern coastal town of Puducherry; 60 consecutive subjects aged > 12 years, predominantly of inbred Tamil population, with head CT evidence of intracerebral hemorrhage not associated with trauma and brain tumors, were recruited. Outcome at three months was measured using Glasgow Outcome scale, NIHSS and mortality. SPSS v 19 was used for statistical analysis. Results: Commonest etiological factor was hypertension, followed by bleeding diathesis, thrombolysis for myocardial infarction, and cortical vein thrombosis. Most frequent locations of hematoma were basal ganglia, thalamus, internal capsule, and cerebral and cerebellar parenchyma. Hematoma volume correlated significantly with systolic and mean arterial pressure but not with diastolic blood pressure. Poor outcome was correlated to size (P < 0.05 and intraventricular extension of hematoma (P < 0.05, and to systolic, diastolic and mean arterial pressure, but not to age, gender, smoking, alcoholism, ischemic heart disease, and blood sugar level. Among diabetic patients with ICH, the size of hematoma (P = 0.04 and severity of coma (P = 0.01 at admission were significantly worse compared to the non-diabetic, but not the outcome at three months [Glasgow outcome scale or mortality (P = 0.94 and 0.14]. Conclusions: The location of hemorrhage and correlation with outcome agreed with the patterns described for the non-white races in prior reports. Independence of outcome to diabetic status despite a more severe initial presentation may indicate importance of good care, even in high risk groups.

    The levels of several coagulation factors, able to influence hemostatic balance, display circadian variations. We hypothesized that the onset and extent of hematoma expansion (HE) following intracerebral hemorrhage (ICH) also display diurnal patterns. We reviewed clinical, laboratory, and radiological data from 111 consecutive patients with spontaneous ICH who had baseline head computed tomography (CT) scans within 3 h of ICH onset and follow-up CT during the following 72 h. We defined any HE (AHE) as any increase in hematoma volume from baseline to follow-up CT and significant HE (SHE) as an absolute increase in hematoma volume >6 mL or relative increase >33%. We categorized the patients into 2 groups based on the timing of the initial CT scans--day group (from 0800 to 2000 h) and night group (from 2000 to 0800 h)--and performed logistic regression analyses. We also analyzed the differences in the rates of HE between the groups during six 4-h periods spanning 24 h, using χ(2) tests. We found that the rates of AHE and SHE were higher in the day versus night group (75% vs. 48%; p = 0.009 for AHE and 47.6% vs. 25.9%; p = 0.047 for SHE). On multivariable logistic regression, day group assignment was independently associated with AHE (adjusted odds ratio = 3.53; p = 0.008) but not with SHE. Both AHE and SHE peaked in the early afternoon (1200-1600 h) and reached a nadir during the 2000 to 2400 h time period, and they were significantly different between the time periods (0000-0400, 0400-0800, 0800-1200, 1200-1600, 1600-2000, and 2000-2400 h); p = 0.002 and 0.029, respectively. These exploratory findings support the presence of a daily pattern in the occurrence of HE, with a higher risk during the day hours. Our results could have implications for future therapeutic efforts targeting HE in ICH and for the triage of ICH patients. They require further validation. © 2015 The Author(s).

    Full Text Available Abstract Background Phase I/II placebo-controlled clinical trials of recombinant Factor VIIa (rFVIIa suggested that administration of rFVIIa within 4 hours after onset of intracerebral hemorrhage (ICH is safe, limits ICH growth, and improves outcomes. We sought to determine the cost-effectiveness of rFVIIa for acute ICH treatment, using published Phase II data. We hypothesized that rFVIIa would have a low marginal cost-effectiveness ratio (mCER given the poor neurologic outcomes after ICH with conventional management. Methods We performed an incremental cost-effectiveness analysis from the societal perspective, considering conventional management vs. 80 ug/kg rFVIIa treatment for acute ICH cases meeting Phase II inclusion criteria. The time frame for the analysis was 1. 25 years: data from the Phase II trial was used for 90 day outcomes and rFVIIa complications – arterial thromboembolic events (ATE. We assumed no substantial cost differences in care between the two strategies except: 1 cost of rFVIIa (for an 80 mcg/kg dose in an 80 kg patient, assumed cost of $6,408; 2 cost of ATE side effects from rFVIIa (which also decrease quality of life and increase the chance of death; and 3 differential monetary costs of outcomes and their impact on quality of life, including disposition (home vs. nursing home, and outpatient vs. inpatient rehabilitation. Sensitivity analyses were performed to explore uncertainty in parameter estimates, impact of rFVIIa cost, direct cost of neurologic outcomes, probability of ATE, and outcomes after ATE. Results In the "base case", treating ICH with rFVIIa dominates the usual care strategy by being more effective and less costly. rFVIIa maintained a mCER Conclusion Based on data from preliminary trials, treating selected ICH patients with rFVIIa results in lower cost and improved clinical outcomes. This potential cost-effectiveness must be considered in light of the Phase III trial results.

    Small intestinal motility (SIM) disorder is a common complication following pediatric intracerebral hemorrhage (ICH), leading to a poor prognosis in patients. Previous studies have shown that ghrelin is involved in SIM in various diseases; however, the role of ghrelin in pediatric ICH‑induced SIM disorder remains to be elucidated. The present study was designed to investigate the association between ghrelin and SIM post‑ICH, and to examine the effect of exogenous ghrelin administration on SIM in vivo. An ICH model was induced in mice by autologous blood infusion. Neurobehavioral deficits were evaluated using a Rotarod test, forelimb placing test, and corner turn test. Intestinal mucosal damage was examined using hematoxylin and eosin staining. SIM was measured using charcoal meal staining. An enzyme‑linked immunosorbent assay was used to evaluate serum levels of ghrelin and nitric oxide (NO). Reverse transcription‑quantitative polymerase chain reaction and western blot analyses were performed to determine the levels of inducible nitric oxide synthase (iNOS), neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS) at the mRNA and protein levels. Nω‑nitro‑L‑arginine methyl ester hydrochloride (L‑NAME), L‑arginine, atropine, phentolamine and propranolol were used to manipulate the putative pathways induced by ghrelin. Neurological dysfunction was observed post‑ICH. ICH caused damage to the intestinal mucosa and delayed SIM. Serum levels of ghrelin increased between 3 h and 3 days, peaking at 12 h, and showed a significant negative correlation with SIM post‑ICH. Ghrelin administration dose‑dependently attenua-ted ICH‑induced SIM disorder. Ghrelin also decreased NO levels by downregulating the mRNA and protein expression levels of iNOS, but not those of nNOS or eNOS, post‑ICH. Consistently, the effect was enhanced by L‑NAME and weakened by L‑arginine, respectively. The protective effect of ghrelin was

    Intracerebral hemorrhage (ICH) contributes significantly to the morbidity and mortality of patients suffering from acute leukemia. While ICH is often identified in autopsy studies of leukemic patients, it is rare for ICH to be the presenting sign that ultimately leads to the diagnosis of leukemia. We report a patient with previously undiagnosed acute precursor B-cell lymphoblastic leukemia (ALL) who presented with diffuse encephalopathy due to ICH in the setting of an acute blast crisis. The diagnosis of ALL was initially suspected, because of the hyperleukocytosis observed on presentation, then confirmed with a bone marrow biopsy and flow cytometry study of the peripheral blood. Furthermore, detection of the BCR/ABL Philadelphia translocation t(9:22)(q34:q11) in this leukemic patient by fluorescent in situ hybridization permitted targeted therapy of the blast crisis with imatinib (Gleevec). Understanding the underlying etiology of ICH is pivotal in its management. This case demonstrates that the presence of hyperleukocytosis in a patient with intracerebral hemorrhage should raise clinical suspicion for acute leukemia as the cause of the ICH.

    Recent trials have challenged the notion that very early mobility benefits patients with acute stroke. It is unclear how cerebral autoregulatory impairments, prevalent in this population, could be affected by mobilization. The safety of mobilizing patients who have external ventricular drainage (EVD) devices for cerebrospinal fluid diversion and intracranial pressure (ICP) monitoring is another concern due to risk of device dislodgment and potential elevation in ICP. We report hemodynamic and ICP responses during progressive, device-assisted mobility interventions performed in a critically ill patient with intracerebral hemorrhage (ICH) requiring two EVDs. A 55-year-old man was admitted to the Neuroscience Critical Care Unit with an acute thalamic ICH and complex intraventricular hemorrhage requiring placement of two EVDs. Progressive mobilization was achieved using mobility technology devices. Range of motion exercises were performed initially, progressing to supine cycle ergometry followed by incremental verticalization using a tilt table. Physiological parameters were recorded before and after the interventions. All mobility interventions were completed without any adverse event or clinically detectable change in the patient's neurological state. Physiological parameters including hemodynamic variables and ICP remained within prescribed goals throughout. Progressive, device-assisted early mobilization was feasible and safe in this critically ill patient with hemorrhagic stroke when titrated by an interdisciplinary team of skilled healthcare professionals. Studies are needed to gain insight into the hemodynamic and neurophysiological responses associated with early mobility in acute stroke to identify subsets of patients who are most likely to benefit from this intervention.

    Magnetic resonance imaging (MRI) has the potential to reveal residues of intracerabral hemorrhage (ICH) throughout life because of the high sensitivity for iron-containing compounds. Gradient-echo T2 * -weighted MR imaging (T2 * MRI) requiring short times for complete acquisition is known to detect small areas of signal loss without surrounding edema representing microbleeds (MBs). MBs in the basal ganglia including the thalami are suggested to be closely related to intracerebral atherosclerotic microangiopathy. We looked for more than 3 MBs in basal ganglia or thalamus of patients with and without episodes of previous ICH. Twelve patients with previous hemorrhagic stroke and 82 without were studied. Multiple MBs in those regions were significantly more frequent in patients with recurrent ICH. In addition, a 76-year-old woman with a history of hypertension was transferred to our hospital for treatment of head injury. She had multiple incidental old basal ganglionic and thalamic MBs. The patient had an asymptomatic primary ICH on computed tomography (CT) 3 months later. In conclusion, MR evidence of multiple MBs in the basal ganglia and thalamus might identify patients at a risk for new and recurrent ICH. Therefore, patients with multiple MBs in those regions should be treated for cerebrovascular risk factors, especially hypertension. Our results appear to confirm the utility of T2 * MRI in hemorrhagic stroke. (author)

    Biomedical magnetic induction measurement is a promising method for the detection of intracerebral hemorrhage (ICH), especially in China. Aiming at overcoming the problem of low sensitivity, a magnetic induction sensor is chosen to replace the conventional sensors. It uses a two-arm Archimedean spiral coil as the exciter and a circular coil as the receiver. In order to carry out high-fidelity simulations, the Chinese head model with real anatomical structure is introduced into this novel sensor for the first time. Simulations have been carried out upon early stage ICH measurements. By calculating the state sensitivity and time sensitivity of the perturbation phase of two types of sensors using the electromagnetic software, we conclude that the primary signal received can be largely reduced using the novel sensor, which could effectively increase the time and state sensitivity simultaneously.

    Control of systolic blood pressure (SBP) after primary intracerebral hemorrhage improves outcomes. Factors determining the number of blood pressure medications (BPM) required for goal SBP<160 mm Hg at discharge are unknown. We hypothesized that higher admission-SBPs require a greater number of BPM for goal discharge-SBP<160 mm Hg, and investigated factors influencing this goal. We conducted a retrospective review of 288 patients who presented with primary intracerebral hemorrhage. Admission-SBP was obtained. Primary outcome was the number of BPM at discharge. Comparison was made between patients presenting with and without a history of hypertension, and patients discharged on <3 and ≥3 BPM. Patients with hypertension history had a higher median admission-SBP compared with those without (180 vs. 157 mm Hg, P=0.0001). In total, 133 of 288 (46.2%) patients were discharged on <3 BPM; 155/288 (53.8%) were discharged on ≥3 BPM. Hypertension history (P<0.0001) and admission-SBP (P<0.0001) predicted the number of BPM at discharge. In patients without hypertension history, every 10 mm Hg increase in SBP resulted in an absolute increase of 0.5 BPM at discharge (P=0.0011), whereas in those with hypertension, the absolute increase was 1.3 BPM (P=0.0012). In comparison with patients discharged on <3 BPM, patients discharged on ≥3 BPM were more likely to have a higher median admission-SBP, be younger in age, belong to the African-American race, have a history of diabetes, have higher median admission-National Institutes of Health Stroke Scale and modified Rankin Scale of 4 to 5 at discharge. An understanding of the factors influencing BPM at discharge may help clinicians better optimize blood pressure control both before and after discharge.

    The prognostic significance of delirium symptoms in intensive care unit (ICU) patients with focal neurologic injury is unclear. To determine the relationship between delirium symptoms and subsequent functional outcomes and quality of life (QOL) after intracerebral hemorrhage. We prospectively enrolled 114 patients. Delirium symptoms were routinely assessed twice daily using the Confusion Assessment Method for the ICU by trained nurses. Functional outcomes were recorded with modified Rankin Scale (scored from 0 [no symptoms] to 6 [dead]), and QOL outcomes with Neuro-QOL at 28 days, 3 months, and 12 months. Thirty-one (27%) patients had delirium symptoms ("ever delirious"), 67 (59%) were never delirious, and the remainder (14%) had persistent coma. Delirium symptoms were nearly always hypoactive, were detected mean 6 days after intracerebral hemorrhage presentation, and were associated with longer ICU length of stay (mean 3.5 d longer in ever vs. never delirious patients; 95% confidence interval, 1.5-8.3; P = 0.004) after correction for age, admit National Institutes of Health (NIH) Stroke Scale, and any benzodiazepine exposure. Delirium symptoms were associated with increased odds of poor outcome at 28 days (odds ratio, 8.7; 95% confidence interval, 1.4-52.5; P = 0.018) after correction for admission NIH Stroke Scale and age, and with worse QOL in the domains of applied cognition-executive function and fatigue after correcting for the NIH Stroke Scale, age, benzodiazepine exposure, and time of follow-up. After focal neurologic injury, delirium symptoms were common despite low rates of infection and sedation exposure, and were predictive of subsequent worse functional outcomes and lower QOL.

    Intracerebral hemorrhage (ICH) is a common and severe form of stroke but is scarcely studied in young adults. Our aim was to study risk factors, clinical presentation and early mortality of ICH in the young and compare these features with older patients. All consecutive patients aged between 16 and 49 diagnosed with a first-ever ICH at the Departments of Neurology or Neurosurgery of the Helsinki University Central Hospital between January 2000 and March 2010 (n = 336) were analyzed retrospectively. Comparisons were performed amongst demographic subgroups and with patients over 49 years of age enrolled between January 2005 and March 2010 (n = 921). In the young patients, median age was 42 years (interquartile range 34-47), 59.5% were male, and annual incidence was 4.9 (95% confidence interval 4.5-5.3) per 100 000. The most prevalent risk factors were hypertension (29.8%) and smoking (22.3%). Compared with older patients hypertensive microangiopathy was less common (25.0% vs. 34.3%, P = 0.002) and structural lesions more common (25.0% vs. 4.9%, P young patients and in 22.5% of those who underwent magnetic resonance imaging and any angiography (n = 89, P = 0.023). Three-month mortality rate was lower in young patients compared with older ones (17.0% vs. 32.7%, P ages (P = 0.324) and independently predicted mortality in older patients but not in the young. Intracerebral hemorrhage (ICH) in the young appears less fatal and has a different spectrum of causes and factors associated with short-term mortality than for the elderly. © 2014 EAN.

    Public reporting efforts currently profile hospitals based on overall stroke mortality rates, yet the "mix" of hemorrhagic and ischemic stroke cases may impact this rate. Using the 2005 to 2006 New York state data, we examined the degree to which hospital stroke mortality rankings varied regarding ischemic versus hemorrhagic versus total stroke. Observed/expected ratio was calculated using the Agency for Healthcare Research and Quality Inpatient Quality Indicator software. The observed/expected ratio and outlier status based on stroke types across hospitals were examined using Pearson correlation coefficients (r) and weighted κ. Overall 30-day stroke mortality rates were 15.2% and varied from 11.3% for ischemic stroke and 37.3% for intracerebral hemorrhage. Hospital risk-adjusted ischemic stroke observed/expected ratio was weakly correlated with its own intracerebral hemorrhage observed/expected ratio (r=0.38). When examining hospital performance group (mortality better, worse, or no different than average), disagreement was observed in 35 of 81 hospitals (κ=0.23). Total stroke mortality observed/expected ratio and rankings were correlated with intracerebral hemorrhage (r=0.61 and κ=0.36) and ischemic stroke (r=0.94 and κ=0.71), but many hospitals still switched classification depending on mortality metrics. However, hospitals treating a higher percent of hemorrhagic stroke did not have a statistically significant higher total stroke mortality rate relative to those treating fewer hemorrhagic strokes. Hospital stroke mortality ratings varied considerably depending on whether ischemic, hemorrhagic, or total stroke mortality rates were used. Public reporting of stroke mortality measures should consider providing risk-adjusted outcome on separate stroke types.

    Full Text Available Background and Purpose: Stroke, which remains the third leading cause of death after heart disease and cancer in developed countries, is a disorder causing permanent neurologic disability. Even though, hemorrhagic strokes are seen less than the ischemic type, they are more fatal. We studied the risk factors for spontaneous intra-cerebral hemorrhage (ICH to direct the proper preventive treatment modalities and the effects of these factors on mortality as well as applied therapeutic strategies on survival. Materials and Methods: The archive records of 106 patients (60 male, 46 female who were diagnosed with spontaneous ICH in Baskent University Hospital, Ankara, between January 2003 and September 2008, were assessed retrospectively. Results: The mean age was found as 62.5. The most frequent risk factor was hypertension (73.5%; 69.2% of these hypertensive patients had uncontrolled blood pressure levels. The mortality rate was detected as 34.9% and patients were found to die approximately within 9 days after ICH. Older age, increased hemorrhage volume, ventricular extension of hemorrhage, and the presence of midline shift were found to significantly correlate with increased mortality (P < 0.05. Patients who underwent surgical therapy showed a longer survival rate (P = 0.016; however, no association was found between medical and surgical therapy in terms of mortality (P = 0.555. Conclusion: The results of this study suggest that effective control of blood pressure is important in the prevention of spontaneous ICH; clinical and radiological findings with treatment modalities influencing mortality should be carefully managed.

    The clinical series consisted of 28 patients with hypertensive intracerebral hematoma observed in the natural course from 1976 through 1978. A total of 114 repeated computer tomographic (CT) examinations were made with an EMI-1010 or an ACTA-0100 scanner. The experimental series consisted of 26 adult mongrel dogs with intracerebral hematoma near the basal ganglia. In 20 dogs, autopsy and histological examinations were performed, and in 12 dogs a total of 31 repeated CT examinations were carried out with an EMI scanner (matrix 320 x 320, high-definition scan). In the clinical series, the time of the decrease in density beginning in the periphery of the hematoma, like the first appearance of ring enhancement and its concentric concentration toward the center of the hematoma, was not affected by the size of the hematoma. However, the time when the intracerebral hematoma was resolved did vary with the size of the hematoma. In the experimental series, the tissue reaction near the periphery of the intracerebral hematoma seemed to be a constant process. First, a necrotic layer appeared, and then this was replaced by immature connective tissue with granular cells, newly formed vessels, and reticulin fibers; finally, the immature layer was gradually transformed into mature connective tissue with collagenous fibers. Moreover, this process of change was not related to the size of the hematoma. The following correlations were suggested by a chronological observation of the CT images and the histological appearance: 1) acute stage - homogeneous high-density extending to the periphery, apperance of a necrotic layer; 2) subacute stage - decreased density spreading from the periphery and formation of ring enhancement, apperance of immature connective tissue with reticulin fibers; 3) chronic stage - concentric concentration of ring enhancement, mature connective tissue with collagenous fibers.

    Seventy-five patients, 37 with putaminal hemorrhage and 38 with thalamic hemorrhage. were examined by CT immediately after the ictus and while the patients were undergoing conservative treatment. The distance was measured on every CT from the center of the pineal body to the inside edge of the hematoma in the putaminal hemorrhage and to the outside edge in the thalamic hemorrhage, by using a slice 5 cm above the orbitomeatal line on which the pineal body was clearly recognizable. At 6 months after ictus, recuperations from hemiplegia were estimated in all patients and compared with the degree of the measured distance on CT. In the group of patients who had recovered completely from hemiplegia, the degrees were more than 28 mm in the cases of putaminal hemorrhage and less than 32 mm in the cases of thalamic hemorrhage. If the degrees were under 25 mm in the putaminal hemorrhage or over 36 mm in the thalamic hemorrhage, no rehabilitation was effective for their paralytic upper extremities. Measurements of the internal capsule were also performed on three fresh brains without cerebral disease. The normal values of the distance were 34.7+-1.0 mm from the center of the pineal body to the outside edge of the posterior limb of the internal capsule and 25.0+-0.9 mm to its inside edge. Judging from these results, it is thought that the attainable limits of avoiding destruction of the posterior limb of the internal capsule by the hematoma are 28 mm in the case of a putaminal hemorrhage and 32 mm in the case of a thalamic hemorrhage. Therefore, it was considered that the internal capsule can be shifted about 7 mm to the medial or lateral side without any direct or indirect effects from the hematoma.

    Full Text Available Skin incision and craniotomy are recognized as an acute noxious stimulation during intracranial surgery which may result in stress response causing an increase in intracranial pressure. Scalp nerve block may be effective in reducing stress response. It can also be used to provide post-operative analgesia. A twenty two years old male with moderate head injury, subdural hemorrhage, intracerebral hemorrhage at right fronto-temporo-parietal region underwent evacuation craniotomy with combined scalp nerve block and general anesthesia at Dr. Hasan General Sadikin Hospital Bandung on August 14th 2012. After induction and before incision of the skin, a scalp nerve block was performed using 0.5% bupivacaine. Hemodynamic (blood pressure and heart rate changes after incision of the skin and craniotomy were not significant, and so was post-operative blood glucose concentration. Post-operative analgetic was given eight hours after the block. The result demonstrates that scalp nerve block using 0.5% bupivacaine successfully blunts stress response and can be used as post-operative analgesia.

    In patients with hypertensive intracerebral hemorrhages, changes in the regional cerebral blood flow (rCBF) after drug-induced blood-pressure reduction were examined by means of subtraction SPECT. The subjects were 38 patients with hypertensive intracerebral hemorrhages; 22 were putaminal hemorrhages (mean age, 56.8 years; mean hematoma volume, 18.4 cc), while 16 were thalamic hemorrhages (mean age, 61.9 years; mean hematoma volume, 7.8 cc). The rCBF was measured by means of SPECT (Tomomatic 64) with 133 Xe inhalation. Trimethaphan (an autonomic ganglion blocker) and diltiazem hydrochloride (a calcium antagonist) were used for the reduction of the blood pressure. The results were as follows: In the acute stage, the mean CBF was reduced when the blood pressure fell by more than 20% in both the putaminal hemorrhages and the thalamic hemorrhages. A similar tendency was observed in the subacute stage, except that a greater reduction in the blood pressure was needed to induce mean CBF reduction. The subtraction of rCBF maps before and after hypotension treatment shows a reduction of the rCBF in the lateral region of hematoma and the contralateral hemisphere. (author)

    Full Text Available Intracerebral hemorrhage (ICH is a devastating type of stroke characterized by bleeding into the brain parenchyma and secondary brain injury resulting from strong neuroinflammatory responses to blood components. Production of prostaglandin E2 (PGE2 is significantly upregulated following ICH and contributes to this inflammatory response in part through its E prostanoid receptor subtype 2 (EP2. Signaling through the EP2 receptor has been shown to affect outcomes of many acute and chronic neurological disorders; although, not yet explored in the context of ICH. Wildtype (WT and EP2 receptor knockout (EP2−/− mice were subjected to ICH, and various anatomical and functional outcomes were assessed by histology and neurobehavioral testing, respectively. When compared with age-matched WT controls, EP2−/− mice had 41.9 ± 4.7% smaller ICH-induced brain lesions and displayed significantly less ipsilateral hemispheric enlargement and incidence of intraventricular hemorrhage. Anatomical outcomes correlated with improved functional recovery as identified by neurological deficit scoring. Histological staining was performed to begin investigating the mechanisms involved in EP2-mediated neurotoxicity after ICH. EP2−/− mice exhibited 45.5 ± 5.8% and 41.4 ± 8.1% less blood and ferric iron accumulation, respectively. Furthermore, significantly less striatal and cortical microgliosis, striatal and cortical astrogliosis, blood–brain barrier breakdown, and peripheral neutrophil infiltration were seen in EP2−/− mice. This study is the first to suggest a deleterious role for the PGE2-EP2 signaling axis in modulating brain injury, inflammation, and functional recovery following ICH. Targeting the EP2 G protein-coupled receptor may represent a new therapeutic avenue for the treatment of hemorrhagic stroke.

    To determine the detectability of intracerebral hematomas with MR imaging at 1.5 T and 0.5 T with fluid attenuated inversion recovery turbo spin-echo (FLAIR) and gradient-echo sequences. Material and Methods: Twenty-seven intracerebral hematomas were created in 25 piglets by injection of venous blood into the brain through a burr hole. All were imaged with T2*-weighted gradient echo sequences (fast field echo, FFE), T2-weighted fluid attenuated inversion recovery turbo spin-echo sequences (FLAIR), T2-weighted turbo spin-echo (TSE) and T1-weighted spin-echo sequences. Follow-up was performed on the 2nd, 4th and 10th postoperative days. Ten animals were additionally investigated with similar sequences at 0.5 T. Histologic correlation was obtained in all cases. Results: T2* FFE sequences detected all acute intracerebral hematomas and demonstrated the size correctly at 1.5 T and 0.5 T. The conspicuity was better at 1.5 T. FLAIR sequences were unreliable in the hyperacute phase at 1.5 T. However, subarachnoid and intraventricular extension was best appreciated with FLAIR images. T2 TSE images were incapable of detecting para ventricular and subarachnoid hemorrhages, but clearly demonstrated intracerebral blood in other locations. T1-weighted images were insensitive to hemorrhage in the acute state but very useful in subacute and chronic hematomas. Conclusion: The safe and reliable diagnosis of intracerebral hemorrhage is probably possible with MR imaging at 1.5 T and 0.5 T even of hematomas less than 90 min old, but requires the application of at least FLAIR, T2* FFE and T1 sequences and is therefore time consuming

    To observe the expressions of neurotrophin receptor homolog 2 (NRH2), nerve growth factor precursor (proNGF), sortilin and neurotrophin receptor p75 (p75NTR) in cerebral tissues around hematomas in the different periods after intracerebral hemorrhage, and explore their relationships to cell apoptosis. The specimens of cerebral tissues around hematomas were collected from the patients undergoing hematoma removal operation after intracerebral hemorrhage. These specimens were divided into four groups, namely ≤ 6 hours, 6-24 hours(including 24 hours), 24-72 hours (including 72 hours) and over 72 hours according to the time from intracerebral hemorrhage to specimen collection. At the same time, 10 brain tissues distant to hemorrhage that dropped in the operative process were collected as a control group. Apoptosis index (AI) was examined in brain cells by terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling (TUNEL). The expressions of NRH2, proNGF, sortilin and p75NTR mRNAs and proteins in brain tissues were detected through real-time quantitative PCR and Western blotting, respectively. Also, the expressions of Bcl-2 and Bax in brain tissues were analyzed using Western blotting. In vitro cultured astrocytes of rat cortex were transfected by NRH2 siRNA or scramble siRNA. The expressions of proNGF, sortilin and p75NTR proteins were detected using Western blotting. AI was higher in all groups of hemorrhage for 6 hours or longer than that in control and ≤ 6 hours groups, and AI in the group of 24-72 hours after intracerebral hemorrhage was the highest. However, there was no significant difference in AI between ≤ 6 hours group and control group. With the extension of intracerebral hemorrhage time, the expression levels of proNGF and p75NTR mRNAs and proteins were gradually elevated, reached the peak in 24-72 hours, and maintained a higher level after 72 hours, whereas there were no significant differences in the above indicators

    Full Text Available Spontaneous deep intracerebral hemorrhage (SDICH is a devastating stroke subtype. The causes of SDICH are heterogeneous. Matrix metalloproteinase-9 (MMP-9, Gelantinase B has been shown to relate to stroke and the development of aneurysm and may increase risks of intracerebral hemorrhage. MMP activities are modulated by their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs. We analyzed the genetic variants of MMP-9 and TIMP-1 and SDICH susceptibility.Associations were tested by logistic regression or general linear models with adjusting for multiple covariables. Multiplicative terms between genes were applied to detect the interaction effects on SDICH. Permutation testing of 1,000 replicates was performed for empirical estimates.In the group of ≥65 years old (y/o, we found associations of SDICH with rs3787268 (Odds ratio [OR] = 0.48, 95% confidence interval [CI] 0.27 to 0.86, P = 0.01 and haplotype1 (Hap1 (OR = 0.48, 95% CI 0.26 to 0.86, P = 0.014. For TIMP1 gene, rs4898 was associated with SDICH in the elder male group (OR = 0.35, 95% CI 0.15 to 0.81, P = 0.015. In contrast, in the younger male group, there were associations of SDICH with rs2250889 (OR = 0.48, 95% CI 0.27 to 0.84, P = 0.01 and Hap3 (OR = 0.61, 95% CI 0.38 to 0.97, P = 0.04. We found significant genetic interaction between TIMP-1 and MMP-9 in SDICH susceptibility among younger male subjects (P = 0.004. In subjects carrying rs4898 minor allele, carriers with Hap3 had lower SDICH risk than non-carriers (OR = 0.19, 95% CI 0.07 to 0.51, P = 0.001. In addition, this study showed that when young males were exposed to alcohol, Hap3 was a protective factor of SDICH (OR = 0.06, 95% CI 0.01 to 0.27, P = 0.0002. In contrast, when they were exposed to smoke, Hap2 carriers had increased risk of SDICH (OR = 2.45, 95% CI 1.05 to 5.73, P = 0.04.This study showed modest to moderate effects of MMP-9 and TIMP-1 polymorphisms on SDICH risks with significant age differences

    Objective: To investigate the mechanism of brain edema formation around the hematoma and the relationship between the formation of brain edema and the changes of regional cerebral blood flow after intracerebral hemorrhage (ICH) in rats, and to provide experimental basis for the clinical treatment of ICH . Methods: Seventy male Sprague-Dawley rats were randomly divided into ICH groups and sham-operated groups. ICH was produced by microinjection of 40 ul fresh autologous blood or saline into the right caudatum. Dynamic CT perfusion imaging was performed, and the parameters of regional cerebral blood flow (rCBF), regional cerebral blood volume (rCBV), and mean transit time (MTT) around the hematoma were calculated respectively. Then the rats were sacrificed, and the water content, sodium, potassium, and calcium concentrations were measured respectively. The correlative study between the water content and rCBF and rCBV were carried out. Results:The gradient of perihematomal hypoperfusion was revealed on CT perfusion maps in ICH groups. The alternation of rCBF around the hematomas were fluctuated, and rCBF reduction was most pronounced at 1 hour afer ICH, then the rCBF gradually returned, reaching the peaks at 6 hours and 24 hours after ICH, respectively. In the meantime, rCBV reduction around the hematoma was most pronounced at 1 hour after ICH. Then the rCBV gradually increased, and reaching the peak at 24 hours. The water contents were gradually increased in the ipsilateral basal ganglia in the animals sacrificed at 6, 24, and 72 hours. The accumulation of water was at its peak at 24 hours, and remained in the animals sacrificed at the 72 hours. The perihemorrhagic water contents correlated significantly with rCBV surrounding hematomas, r=0.372 (one-tailed), P<0.05. Conclusion: The perihemorrhagic brain edema results from the common effects of the blood-brain-barrier disruption, cytotoxic edema, and the accumulation of osmotically active substances. The r

    The computed tomographic angiography (CTA) spot sign is associated with intracerebral hemorrhage (ICH) expansion and may mark those patients most likely to benefit from intensive blood pressure (BP) reduction. To investigate whether the spot sign is associated with ICH expansion across a wide range of centers and whether intensive BP reduction decreases hematoma expansion and improves outcome in patients with ICH and a spot sign. SCORE-IT (Spot Sign Score in Restricting ICH Growth) is a preplanned prospective observational study nested in the Antihypertensive Treatment of Acute Cerebral Hemorrhage II (ATACH-II) randomized clinical trial. Participants included consecutive patients with primary ICH who underwent a CTA within 8 hours from onset at 59 sites from May 15, 2011, through December 19, 2015. Data were analyzed for the present study from July 1 to August 31, 2016. Patients in ATACH-II were randomized to intensive (systolic BP target, spot sign, and 24 of 123 without missing data (19.5%) experienced ICH expansion. The spot sign was associated with expansion with sensitivity of 0.54 (95% CI, 0.34-0.74) and specificity of 0.63 (95% CI, 0.53-0.72). After adjustment for potential confounders, intensive BP treatment was not associated with a significant reduction of ICH expansion (relative risk, 0.83; 95% CI, 0.27-2.51; P = .74) or improved outcome (relative risk of 90-day modified Rankin Scale score ≥4, 1.24; 95% CI, 0.53-2.91; P = .62) in spot sign-positive patients. The predictive performance of the spot sign for ICH expansion was lower than in prior reports from single-center studies. No evidence suggested that patients with ICH and a spot sign specifically benefit from intensive BP reduction. clinicaltrials.gov Identifier: NCT01176565.

    Blend sign (BS) and black hole sign (BHS) on non-contrast computed tomography (NCCT) and spot sign (SS) on CT-angiography (CTA) are indicators of early hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, their independent contributions to outcome have not been well explored. In this retrospective study, inclusion criteria were: 1) spontaneous ICH and 2) NCCT and CTA performed on admission within 6 hours after onset of symptoms. Discharge outcome was dichotomized as good (modified Rankin Scale [mRS] 0-3) and poor (mRS 4-6) outcomes. The impacts of BHS, BS and SS on outcome were assessed in univariate and multivariable logistic regression models. Of 182 patients with spontaneous ICH, 26 (14.3%) presented with BHS, 37 (20.3%) with BS and 39 (21.4%) with SS. There was a substantial correlation between SS and BS (κ=0.701) and a moderate correlation between SS and BHS (κ=0.424). In univariable logistic regression, higher baseline hematoma volume ( P <0.001), intraventricular hemorrhage ( P =0.002) and the presence of BHS/BS/SS (all P <0.001) on admission CT scan were associated with poor outcome. Multivariable analysis identified intraventricular haemorrhage (odds ratio [OR] 2.22 per mL, P =0.022), baseline hematoma volume (OR 1.03 per mL, P <0.001) and SS on CTA (OR 11.43, P <0.001) as independent predictors of poor outcome, showing that SS compared to BS and BHS was more powerful to predict poor outcome. The NCCT BHS and BS are correlated with the CTA SS and are reliable predictors of poor outcome in patients with ICH. Of the CT variables indicating early hematoma expansion, SS on CTA was the most reliable outcome predictor. However, given their correlation with SS on CTA, BS and BHS on NCCT can be useful for predicting outcome if CTA is not obtainable.

Method We used multidetector computed tomography angiography to study 65 consecutive patients (40 men, 61.5%, with ages varying from 33 to 89 years (median age 55 years. Clinical and imaging findings were correlated with the findings based on the initial imaging. Results Of the individuals who presented a spot sign, 73.7% died (in-hospital mortality, whereas in the absence of a spot sign the mortality rate was 43.0%. Although expansion of ICH was detected in 75% of the patients with a spot sign, expansion was observed in only 9.0% of the patients who did not present a spot sign. Conclusions The spot sign strongly predicted expansion in non-traumatic ICH and an increased risk of in-hospital mortality.

    To investigate the association between genetic variations of matrix metalloproteinase 9 (MMP9) gene and intracerebral hemorrhage (ICH) susceptibility in Chinese Han population. The clinical data and peripheral blood samples from the patients with ICH and hypertension, and controlled subjects with hypertension only, were collected. MassARRAY Analyzer was used to genotype the tagger single nucleotide polymorphism (SNP) of MMP9 gene. Haploview4.2 and Unphased3.1.7 were employed to construct haplotypes and to analyze the association between genetic variations (alleles, genotypes and haplotypes) of MMP9 gene and ICH susceptibility. 181 patients with ICH and hypertension, and 197 patients with hypertension only, were recruited between Sep 2009 and Oct 2010. Patients in the ICH group were younger (61.80 ± 13.27 vs. 72.44 ± 12.71 years, ppopulation. Our logistical regression analysis showed that there were no significant associations between genetic variations of the MPP9 gene and ICH susceptibility (all p>0.05). The genetic variations of MMP9 gene were not significantly associated with ICH susceptibility in the Chinese Han population. Copyright © 2014 Elsevier B.V. All rights reserved.

    Hematoma expansion is related to unfavorable prognosis in intracerebral hemorrhage (ICH). The black hole sign is a novel marker on non-contrast computed tomography for predicting hematoma expansion. However, its predictive values are different in previous studies. Thus, this meta-analysis was conducted to evaluate the predictive significance of the black hole sign for hematoma expansion in ICH. A systematic literature search was performed. Original researches on the association between the black hole sign and hematoma expansion in ICH were included. Sensitivity and specificity were pooled to assess the predictive accuracy. Summary receiver operating characteristics curve (SROC) was developed. Deeks' funnel plot asymmetry test was used to assess the publication bias. Five studies with a total of 1495 patients were included in this study. The pooled sensitivity and specificity of the black hole sign for predicting hematoma expansion were 0.30 and 0.91, respectively. The area under the curve was 0.78 in SROC curve. There was no significant publication bias. This meta-analysis shows that the black hole sign is a helpful imaging marker for predicting hematoma expansion in ICH. Although the black hole sign has a relatively low sensitivity, its specificity is relatively high. Copyright © 2018 Elsevier Inc. All rights reserved.

    This study evaluated the differences in spontaneous intracerebral hemorrhage (sICH) between rural and urban areas of Taiwan with big data analysis. We used big data analytics and visualization tools to examine government open data, which included the residents' health medical administrative data, economic status, educational status, and relevant information. The study subjects included sICH patients of Taipei region (29,741 cases) and Eastern Taiwan (4565 cases). The incidence of sICH per 100,000 population per year in Eastern Taiwan (71.3 cases) was significantly higher than that of the Taipei region (42.3 cases). The mean coverage area per hospital in Eastern Taiwan (452.4 km²) was significantly larger than the Taipei region (24 km²). The residents educational level in the Taipei region was significantly higher than that in Eastern Taiwan. The mean hospital length of stay in the Taipei region (17.9 days) was significantly greater than that in Eastern Taiwan (16.3 days) ( p < 0.001). There were no significant differences in other medical profiles between two areas. Distance and educational barriers were two possible reasons for the higher incidence of sICH in the rural area of Eastern Taiwan. Further studies are necessary in order to understand these phenomena in greater depth.

    Full Text Available BACKGROUND AND PURPOSE: The National Institutes of Health Stroke Scale (NIHSS is commonly used to measure neurologic function and guide treatment after spontaneous intracerebral hemorrhage (ICH in routine stroke clinics. We evaluated its reliability and sensitivity to detect change with consecutive and unique rater combinations in a real-world setting. METHODS: Conservative measures of interrater reliability (unweighted Kappa (κ, Intraclass Correlation Coefficient (ICC1,1 and sensitivity to detect change (Minimal Detectable Difference (MDD were estimated. Sixty-one repeated ratings were completed within 1 week after ICH by physicians and nurses with no investigator intervention. RESULTS: Reliability (consistency of the NIHSS total score was good for both physicians vs. nurses and nurses vs. nurses (ICC=0.78, 95%CI: 0.58-0.89 and ICC=0.75, 95%CI: 0.55-0.87 respectively in this scenario. Reliability (agreement of items 1C and 9 were excellent (κ>=0.61 for both rater comparisons, however, reliability was poor to fair on most remaining items (κ:0.01-0.60, with item 11 being completely unreliable in this scenario (κ=10 points need to be observed for clinicians to be confident that real changes had occurred within 1 week after ICH.

    Existing data on perfusion imaging assumes the perihemorrhagic zone (PHZ) in patients with intracerebral hemorrhage (ICH) to be size steady. This study investigates the size of the perihemorrhagic zone (PHZ) in patients with lobar ICH in relation to hematoma volume during the course of treatment using perfusion CT (PCT). The present analysis is based on a previously reported cohort of 20 patients undergoing surgical evacuation for lobar SICH, with pre- and early postoperative PCT scanning. Time to peak of the residue function (T max ) was measured based on the 360 cortical banding method and singular value decomposition. The size of PHZ was determined before and after treatment and correlated with hematoma volume. Preoperative mean hematoma volume constituted 63.0 ml (interquartile ranges (IQR) 39.7-99.4 ml), which correlated significantly (r = 0.563, p = 0.010) with mean PHZ size (5.67 cm, IQR 5.44-8.17 cm). Following a surgical hematoma evacuation, mean hematoma volume was reduced to 2.5 ml IQR 0.0-9.5 ml, which also resulted in a significant reduction of PHZ size to 0.45 cm(IQR 0.0-1.36 cm; p < 0.001). There was no association between postoperative hematoma volume and size of the PHZ. Our findings illustrate that the extent of the PHZ cannot be generally assumed to be constant in size and that this differs significantly following hematoma reduction in patients with space occupying lobar SICH.

    The preventive effect of aggressive blood pressure lowering on hematoma enlargement was investigated in patients with ultra-acute spontaneous intracerebral hemorrhage (ICH). Retrospective review of 248 patients (145 males, 103 females) with spontaneous ICH treated in our hospital between 2005 and 2008 identified patients with ultra-acute ICH who were directly taken to our institute by ambulance within 3 hours after onset. Patients who could not be assessed twice by computed tomography (CT) within 24 hours after arrival were excluded. Systolic blood pressure (SBP) was aggressively controlled in all patients using intravenous nicardipine to below 140 mmHg as soon as possible after diagnosis of ICH with CT. Hematoma enlargement was defined as increase in volume of more than 33% or more than 12.5 ml in the first 24 hours. Hematoma enlargement was observed in 11 of the 73 patients (15.0%). The time course of SBP change was not significantly different in patients with and without hematoma enlargement. The incidence of hematoma enlargement in patients with ultra-acute ICH in this study was 15.0%, which was lower than that in other series in which blood pressure was not reduced aggressively. This finding suggests that aggressive SBP lowering to below 140 mmHg has a preventive effect on hematoma enlargement in patients with ultra-acute ICH. (author)

    Intracerebral hemorrhage (ICH) is a devastating subtype of stroke. Patients with ICH have poor functional outcomes. The association between blood glucose level and functional outcome in ICH remains unclear. This systematic review and meta-analysis aimed to investigate the association between blood glucose level and functional outcomes in patients with ICH. Literature was searched systemically in PubMed, EMBASE, Web of Science, and Cochrane Library. Published cohort studies evaluating the association between blood glucose and functional outcome in patients with ICH were included. This meta-analysis was performed using odds ratios (ORs) and 95% confidence intervals (CIs). A total of 16 studies were included in our meta-analysis. Our data show that hyperglycemia defined by cutoff values was significantly associated with unfavorable functional outcome (OR, 1.80; 95% CI, 1.36-2.39; P analysis also suggested a significant association between increased blood glucose levels and functional outcomes (OR, 1.05; 95% CI, 1.03-1.07; P functional outcome in ICH. Further studies with larger sample sizes, more time points, and longer follow-up times are necessary to confirm this association. Copyright © 2018 Elsevier Inc. All rights reserved.

    Existing data on perfusion imaging assumes the perihemorrhagic zone (PHZ) in patients with intracerebral hemorrhage (ICH) to be size steady. This study investigates the size of the perihemorrhagic zone (PHZ) in patients with lobar ICH in relation to hematoma volume during the course of treatment using perfusion CT (PCT). The present analysis is based on a previously reported cohort of 20 patients undergoing surgical evacuation for lobar SICH, with pre- and early postoperative PCT scanning. Time to peak of the residue function (T{sub max}) was measured based on the 360 cortical banding method and singular value decomposition. The size of PHZ was determined before and after treatment and correlated with hematoma volume. Preoperative mean hematoma volume constituted 63.0 ml (interquartile ranges (IQR) 39.7-99.4 ml), which correlated significantly (r = 0.563, p = 0.010) with mean PHZ size (5.67 cm, IQR 5.44-8.17 cm). Following a surgical hematoma evacuation, mean hematoma volume was reduced to 2.5 ml IQR 0.0-9.5 ml, which also resulted in a significant reduction of PHZ size to 0.45 cm(IQR 0.0-1.36 cm; p < 0.001). There was no association between postoperative hematoma volume and size of the PHZ. Our findings illustrate that the extent of the PHZ cannot be generally assumed to be constant in size and that this differs significantly following hematoma reduction in patients with space occupying lobar SICH.

    Full Text Available Intracerebral hemorrhage (ICH is a subtype of stroke associated with high morbidity and mortality rates. No proven treatments are available for this condition. Iron-mediated free radical injury is associated with secondary damage following ICH. Deferoxamine (DFX, a ferric-iron chelator, is a candidate drug for the treatment of ICH. We performed a systematic review of studies involving the administration of DFX following ICH. In total, 20 studies were identified that described the efficacy of DFX in animal models of ICH and assessed changes in the brain water content, neurobehavioral score, or both. DFX reduced the brain water content by 85.7% in animal models of ICH (-0.86, 95% CI: -.48- -0.23; P < 0.01; 23 comparisons, and improved the neurobehavioral score by -1.08 (95% CI: -1.23- -0.92; P < 0.01; 62 comparisons. DFX was most efficacious when administered 2-4 h after ICH at a dose of 10-50 mg/kg depending on species, and this beneficial effect remained for up to 24 h postinjury. The efficacy was higher with phenobarbital anesthesia, intramuscular injection, and lysed erythrocyte infusion, and in Fischer 344 rats or aged animals. Overall, although DFX was found to be effective in experimental ICH, additional confirmation is needed due to possible publication bias, poor study quality, and the limited number of studies conducting clinical trials.

    Objective: To discuss the feasibility and effectiveness of transarterial embolization for the management of postoperative massive hemorrhage in patients with abdominal tumors. Methods: Between January 2004 and December 2009 in authors' hospital transarterial embolization for postoperative massive hemorrhage was performed in thirteen patients with abdominal tumors. The clinical data and the technical points were retrospectively analyzed. Results: Of 13 patients,the bleeding was completely controlled in 10 after single embolization procedure. Re-bleeding occurred in the other 3 patients, and angiography showed the new bleeding arteries. Trans arterial embolization was carried out again, and the bleeding was successfully stopped in 2 patients. The remaining one patient had to be treated with surgery as the microcatheter could not be super-selectively placed into the bleeding vessel. The overall clinical success rate of trans arterial embolization for postoperative massive hemorrhage was 92% (12 /13). No severe complications occurred. Conclusion: Trans arterial embolization is a safe and effective treatment for postoperative massive hemorrhage in patients with abdominal tumors. (authors)

    It is generally accepted that cases of aphasia can be divided into several groups according to verbal fluency, auditory comprehension, and repetition abilities. Although many authors have studied aphasia and its location by means of a CT scan, the primary lesion on a CT scan with regard to the subtypes of aphasia still remains controversial. In this report we present our new CT classification for the syndromes of aphasia and the prognosis. Twenty-one patients with intracerebral hematoma (ICH) were followed up for more than 3 months after onset. ICH was classified according to the mode of the horizontal extension of the hematoma on a CT scan. Four lines were decided as follows: Line (a) is between the anterior horn of the lateral ventricle and the midpoint of the third ventricle; Line (b) is the vertical line to the saggital line which originates from the midpoint of the third ventricle; Line (c) is between the trigone of the lateral ventricle and the midpoint of the third ventricle. The CT classification consisted of 4 types: in Type A, ICH was located anterior to line (a); in Type B, ICH was located between line (a) and line (b); in Type C, ICH was located between line (b) and line (c); Type B+C, was a combination of Type B and Type C. Transcortical motor aphasia belonged to the Type A group. Transcortical sensory aphasia belonged to the Type B and Type B+C groups. Wernicke's and anomic aphasia belonged to the Type C group. Conduction and global aphasia belonged to the Type B+C group. Pure Broca's aphasia could not be observed in this series. Several relationships between the syndromes of aphasia and its CT findings were evident. On the other hand, the syndromes of aphasia and the degree of recovery were not correlated, except for global aphasia. (author).

    Full Text Available Currently, we lack well-established guidelines for the emergency management of severe immune thrombocytopenia (ITP with life-threatening bleeding. We now report the management of two patients with severe ITP, complicated by substantial cerebral hemorrhage, requiring urgent surgery due to refractory intracranial hypertension. To rapidly boost platelet counts (PCs, corticosteroids, intravenous immunoglobulin, and iterative platelet transfusions were given; all were ineffectual. Romiplostim, a thrombopoietin receptor agonist, was then administered as an “on demand therapy,” with the result that a rapid and sustained increase of PCs was achieved, thus allowing for postoperative hemostasis. Both patients recovered good neurological condition, suggesting the potential utility of romiplostim, in combined therapy, for the emergency management of severe ITP.

    To investigate the relationship between single nucleotide polymorphisms or haplotypes of COL4A1 gene and the outcome of intracerebral hemorrhage (ICH). In our study, 181 patients with hypertensive ICH were enrolled and followed up at 3 and 6 months. Outcome data included any cause of death and disability. Genomic DNA was extracted by DNA extraction kit, and the 6 single nucleotide polymorphism genotyping of the COL4A1 gene was detected through MassARRAY Analyzer. Unphased 3.1.4 and SPSS 19.0 were used to analyze the association between alleles, genotypes, and haplotypes of the COL4A1 gene and the outcomes of ICH. Of the 181 patients with hypertensive ICH, 12 were lost in follow-up, which accounted for 6.6%. Our association analysis showed that the rs532625 AA genotype of the COL4A1 gene may increase risk of disability at 3 months; the rs532625 A allele and AA genotype were association factors of the risk of disability at 6 months; the rs532625 AA genotype was an association factor of the risk of death/disability at 6 months. After adjusting for gender, age, coma, and severe neurologic deficits, only the rs532625 AA genotype was independently associated with the risk of disability at 3 and 6 months and the risk of death/disability at 6 months. Our study found that the rs532625 AA genotype in the COL4A1 gene was independently associated with the risk of disability at 3 and 6 months and death/disability at 6 months in a Chinese Han population. These conclusions need to be verified in future studies with larger samples. Copyright © 2018 Elsevier Inc. All rights reserved.

    BACKGROUND Early hematoma growth is associated with poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). The swirl sign (SS) and the black hole sign (BHS) are imaging markers in ICH patients. The aim of this study was to compare the predictive value of these 2 signs for early hematoma growth. MATERIAL AND METHODS ICH patients were screened for the appearance of the 2 signs within 6 h after onset of symptoms. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 2 signs in predicting early hematoma growth were assessed. The accuracy of the 2 signs in predicting early hematoma growth was analyzed by receiver-operator analysis. RESULTS A total of 200 patients were enrolled in this study. BHS was found in 30 (15%) patients, and SS was found in 70 (35%) patients. Of the 71 patients with early hematoma growth, BHS was found on initial computed tomography scans in 24 (33.8%) and SS in 33 (46.5%). The sensitivity, specificity, PPV, and NPV of BHS for predicting early hematoma growth were 33.8%, 95.3%, 80.0%, and 72.0%, respectively. The sensitivity, specificity, PPV, and NPV of SS were 46.5%, 71.3%, 47.0%, and 71.0%, respectively. The area under the curve was 0.646 for BHS and 0.589 for SS (P=0.08). Multivariate logistic regression showed that presence of BHS is an independent predictor of early hematoma growth. CONCLUSIONS The Black hole sign seems to be good predictor for hematoma growth. The presence of swirl sign on admission CT does not independently predict hematoma growth in patients with ICH.

    To access the feasibility of clinically available 3T MRI to detect the migration of labeled neural stem cells (NSCs) in intracerebral hemorrhage (ICH) in a rat model. The ethics committee of our institution approved this study. ICH was induced by the injection of collagenase type IV into the right striatum of ten Sprague-Dawley rats. Human NSCs conjugated with Feridex (superparamagnetic iron oxide: SPIO) were transplanted into the left striatum one week after ICH induction. MRI was performed on a 3T scanner during the first, second, third, fourth, and sixth weeks post-transplantation. MRI was obtained using coronal T2- and T2 * -weighted sequences. Two rats were sacrificed every week after in vivo MRI in order to analyze the histological findings. ICH in the right striatum was detected by MRI one and two weeks after transplantation without migration of the NSCs. There was no migration of the NSCs as seen on the histological findings one week after transplantation. The histological findings two weeks after transplantation showed a small number of NSCs along the corpus callosum. On MRI three weeks after transplantation, there was a hypointense line along the corpus callosum and decreased signal intensity in the right periventricular region. Histological findings three weeks after transplantation confirmed the presence of the hypointense line representing SPIO-labeled NSCs. MRI four and six weeks after transplantation showed a hypointense spot in the right periventricular region. The histological findings four and six weeks after transplantation showed the presence of prominent NSCs in the right periventricular region. 3T MRI can detect the migration of NSCs in rats with ICH along the corpus callosum. Therefore, 3T MRI could be feasible for detecting the migration of NSCs in the clinical setting of stem cell therapy

    Α limited number of genetic variants have been linked to the development of intracerebral hemorrhage (ICH). Ιntegrin AV and/or B8-deficient mice were found to develop ICH. The present candidate gene association study was designed to investigate possible influence of integrin AV (ITGAV) and integrin B8 (ITGB8) gene region polymorphisms on the risk of ICH. 1015 participants (250 Greek and 193 Polish patients with primary ICH and 250 Greek and 322 Polish controls) were included in the study. Using logistic regression analyses, 11 tag single nucleotide polymorphisms (SNPs) for ITGAV and 11 for ITGB8 gene were tested for associations with ICH risk, lobar ICH risk and non-lobar ICH after adjustment for age, gender, history of hypertension and country of origin. Linear regression models were used to test the effect of tag SNPs on the ICH age of onset. Correction for multiple comparisons was carried out. The rs7565633 tag SNP of the ITGAV gene was independently associated with the risk of lobar ICH in the codominant model of inheritance [odds ratio (95 % confidence interval (CI)) 0.56 (0.36-0.86), p = 0.0013]. Furthermore, heterozygous individuals of the rs10251386 and the rs10239099 of the ITGB8 gene had significantly lower age of ICH onset compared to the wild-type genotypes [regression coefficient (b) -3.884 (95 % CI -6.519, -1.249), p = 0.0039 and b = -4.502 (95 % CI -7.159, -1.845), p = 0.0009, respectively]. The present study provides preliminary indication for an influence of ITGAV gene tag SNP in the development of lobar ICH and of ITGB8 gene variants in the age of ICH onset.

    The purpose of this study was to evaluate the value of 320-detector row CT used to detect crossed cerebellar diaschisis (CCD) in patients with unilateral supratentorial spontaneous intracerebral hemorrhage (SICH). We investigated 62 of 156 patients with unilateral supratentorial SICH using 320-detector row CT scanning. Regional cerebral blood flow (rCBF), cerebral blood volume (rCBV), mean transit time (rMTT), and time to peak (rTTP) levels were measured in different regions of interest (ROIs) that were manually outlined on computed tomography perfusion (CTP) for the cerebrum, including normal-appearing brain tissue that surrounded the perilesional low-density area (NA) and the perihematomal low-density area (PA) in all patients and the cerebellum (ipsilateral and contralateral) in CCD-positive patients. Of 62 cases, a total of 14 met the criteria for CCD due to cerebellar perfusion asymmetry on CTP maps. In the quantitative analysis, significant differences were found in the perfusion parameters between the contralateral and ipsilateral cerebellum in CCD-positive cases. No significant differences were found between the CCD-positive group and the CCD-negative group according to the hematoma volume, NIHSS scores, and cerebral perfusion abnormality (each P > 0.05). The correlation analysis of the degree of NA, PA perfusion abnormality, and the degree of CCD severity showed negative and significant linear correlations (R, -0.66∝-0.56; P < 0.05). 320-detector row CT is a robust and practicable method for the comprehensive primary imaging work-up of CCD in unilateral supratentorial SICH patients.

    Prognostication following intracerebral hemorrhage (ICH) has focused on poor outcome at the expense of lumping together mild and moderate disability. We aimed to develop a novel approach at classifying a range of disability following ICH. The Virtual International Stroke Trial Archive collaboration database was searched for patients with ICH and known volume of ICH on baseline CT scans. Disability was partitioned into mild [modified Rankin Scale (mRS) at 90 days of 0-2], moderate (mRS = 3-4), and severe disabilities (mRS = 5-6). We used binary and trichotomy decision tree methodology. The data were randomly divided into training (2/3 of data) and validation (1/3 data) datasets. The area under the receiver operating characteristic curve (AUC) was used to calculate the accuracy of the decision tree model. We identified 957 patients, age 65.9 ± 12.3 years, 63.7% males, and ICH volume 22.6 ± 22.1 ml. The binary tree showed that lower ICH volume (27.9 ml), older age (>69.5 years), and low Glasgow Coma Scale (tree showed that ICH volume, age, and serum glucose can separate mild, moderate, and severe disability groups with AUC 0.79 (95% CI 0.71-0.87). Both the binary and trichotomy methods provide equivalent discrimination of disability outcome after ICH. The trichotomy method can classify three categories at once, whereas this action was not possible with the binary method. The trichotomy method may be of use to clinicians and trialists for classifying a range of disability in ICH.

    Hypertensive intracerebral hemorrhage (ICH) is a rapidly evolutional pathology, inducing necrotic cell death followed by apoptosis, and alters gene expression levels in surrounding tissue of an injured brain. For ICH therapy by controlled gene release, the development of intravenously administrable delivery vectors to promote the penetration across the blood-brain barrier (BBB) is a critical challenge. To enhance transfer efficiency of genetic materials under hypoxic conditions, polybutylcyanoacrylate (PBCA) nanoparticles (NPs) were used to mediate the intracellular transport of plasmid neurotrophin-3 (NT-3) containing hormone response element (HRE) with a cytomegalovirus (cmv) promoter and to differentiate induced pluripotent stem cells (iPSCs). The differentiation ability of iPSCs to neurons was justified by various immunological stains for protein fluorescence. The effect of PBCA NP/cmvNT-3-HRE complexes on treating ICH rats was studied by immunostaining, western blotting and Nissl staining. We found that the treatments with PBCA NP/cmvNT-3-HRE complexes increased the capability of differentiating iPSCs to express NT-3, TrkC and MAP-2. Moreover, PBCA NPs could protect cmvNT-3-HRE against degradation with EcoRI/PstI and DNase I in vitro and raise the delivery across the BBB in vivo. The administration of PBCA NP/cmvNT-3-HRE complexes increased the expression of NT-3, inhibited the expression of apoptosis-inducing factor, cleaved caspase-3 and DNA fragmentation, and reduced the cell death rate after ICH in vivo. PBCA NPs are demonstrated as an appropriate delivery system for carrying cmvNT-3-HRE to the brain for ICH therapy. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Background/Aims: HIF-1α is accumulated in the cellular nucleus and cytoplasm under conditions of oxygen deprivation and engaged in pathophysiologic changes of homeostasis by modulating the expression of several target genes. As an endogenous signaling protein, HIF-1α contributes to in neuroprotection, erythropoiesis, and apoptosis modulation. The purpose of this study was to examine the role played by HIF-1α in regulating neurological injury evoked by intracerebral hemorrhage (ICH through its downstream product, namely vascular endothelial growth factor (VEGF. In particular, we examined the effects of diabetic hyperglycemia on HIF-1α response in the processing of ICH. Methods: ELISA was used to measure HIF-1α and VEGF; and Western Blot analysis to examine the protein expression of VEGFR-2 and Caspase-3. Neurological Severity Score and brain water content were used to indicate neurological function and brain edema. Results: HIF-1α and VEGF were significantly increased in the brain after induction of ICH in non-diabetic control rats and diabetic rats; however, the amplified levels of HIF-1α and VEGF were attenuated in diabetic rats (Pvs. non-diabetic rats as compared with non-diabetic rats. Also, the protein expression of VEGF receptor subtype 2 was significantly less in the brain of diabetic rats (Pvs. non-diabetic rats. Further, cerebral infusion of HIF-1 activator stabilized VEGF levels, attenuated Caspase-3 and improved neurological deficits induced by ICH and the effects are smaller in diabetic animals. Conclusion: HIF-1α activated by ICH likely plays a beneficial role via VEGF mechanisms and response of HIF-1α is largely impaired in diabetes. This has pharmacological implications to target specific HIF-1α and VEGF pathway for neuronal dysfunction and vulnerability related to ICH.

    Full Text Available Spontaneous intracerebral hemorrhage (ICH is a devastating form of stroke, which leads to a high rate of mortality and poor neurological outcomes worldwide. Thrombolytic evacuation with urokinase-type plasminogen activator (uPA or tissue-type plasminogen activator (tPA has been showed to be a hopeful treatment for ICH. However, to the best of our knowledge, no clinical trials were reported to compare the efficacy and safety of these two fibrinolytics administrated following minimally invasive stereotactic puncture (MISP in patients with spontaneous basal ganglia ICH. Therefore, the authors intended here to evaluate the differential impact of uPA and tPA in a retrospective study. In the present study, a total of 86 patients with spontaneous ICH in basal ganglia using MISP received either uPA (uPA group, n = 45 or tPA (tPA group, n = 41, respectively. The clinical baseline characteristics prior to the operation were collected. In addition, therapeutic responses were assessed by the short-term outcomes within 30 days postoperation, as well as long-term outcomes at 1 year postoperation. Our findings showed that, in comparison with tPA, uPA was able to better promote hematoma evacuation and ameliorate perihematomal edema, but the differences were not statistically significant. Moreover, the long-term functional outcomes of both groups were similar, with no statistical difference. In conclusion, these results provide evidence supporting that uPA and tPA are similar in the efficacy and safety for thrombolytic evacuation in combination with MISP in patients with spontaneous basal ganglia ICH.

    Full Text Available BackgroundHypertension (HTN is the most common cause of spontaneous intracerebral hemorrhage (ICH. The aim of this study is to investigate the role of resistant HTN in patients with ICH.Methods and resultsWe conducted a retrospective study of all consecutive ICH admissions at our medical center from November 2013 to October 2015. The clinical features of patients with resistant HTN (requiring four or more antihypertensive agents to keep systolic blood pressure <140 mm Hg were compared with those with responsive HTN (requiring three or fewer agents. Of the 152 patients with hypertensive ICH, 48 (31.6% had resistant HTN. Resistant HTN was independently associated with higher body mass index and proteinuria. Compared to the responsive group, patients with resistant HTN had higher initial blood pressures and greater requirement for ventilator support, hematoma evacuation, hypertonic saline therapy, and nicardipine infusion. Resistant HTN increases length of stay (LOS in the intensive care unit (ICU (4.2 vs 2.1 days; p = 0.007 and in the hospital (11.5 vs 7.0 days; p = 0.003. Multivariate regression analysis showed that the rate of systolic blood pressure >140 mm Hg and duration of nicardipine infusion were independently associated with LOS in the ICU. There was no significant difference in hematoma expansion and functional outcome at hospital discharge between the two groups.ConclusionResistant HTN in patients with ICH is associated with more medical interventions and longer LOS without effecting outcome at hospital discharge.

    Full Text Available Abstract Background Spontaneous intracerebral hemorrhage (ICH is a devastating form of stroke with the high mortality twofold to sixfold higher than that for ischemic stroke. But the treatment of haematomas within the basal ganglia continues to be a matter of debate among neurologists and neurosurgeons. The purpose of this study is to judge the clinical value of minimally invasive stereotactic puncture therapy (MISPT on acute ICH. Methods A prospective controlled study was undertaken. The clinical trial was in compliance with the WMA Declaration of Helsinki - Ethical Principles for Medical Research Involving Human Subjects. According to the enrollment criterion, there were 168 acute ICH cases analyzed, of which 90 cases were performed by MISPT ( MISPT group, MG and 78 cases by Conventional craniotomy (CC group, CG, by means of compare of Glasgow Coma Scale(GCS score, postoperative complications(PC and rebleeding incidence(RI, moreover, long-term outcome of 1 year postoperation judged by Glasgow Outcome Scale (GOS, Barthel Index (BI, modified Rankin Scale (mRS and case fatality(CF. Results MG patients showed obvious amelioration in GCS score compared with that of CG. The total incidence of PC in MG decreased obviously compared with that of CG. The incidences of rebleeding in MG and CG were 10.0% and 15.4% respectively. There was no obvious difference between CFs of MG and CG. For three parameters representing long-term outcome, the GOS, BI and mRS in MG were ameliorated significantly than that of CG. Conclusion These data suggested that the advantage of MISPT was displayed in minute trauma and safety, and seemed to be feasible and to had a trend towards improved long-term outcome.

    Whether to resume antithrombotic treatment after oral anticoagulant-related intracerebral haemorrhage (OAC-ICH) is debatable. In this study, we aimed at investigating long-term outcome associated with OAC resumption after warfarin-related ICH, in comparison with secondary prevention strategies with platelet inhibitors or antithrombotic discontinuation. Participants were patients who sustained an incident ICH during warfarin treatment (2002-2014) included in the Multicenter Study on Cerebral Hemorrhage in Italy. Primary end-point was a composite of ischemic stroke/systemic embolism (SE) and all-cause mortality. Secondary end-points were ischemic stroke/SE, all-cause mortality and major recurrent bleeding. We computed individual propensity score (PS) as the probability that a patient resumes OACs or other agents given his pre-treatment variables, and performed Cox multivariable analysis using Inverse Probability of Treatment Weighting (IPTW) procedure. A total of 244 patients qualified for the analysis. Unlike antiplatelet agents, OAC resumption was associated with a lower rate of the primary end-point (weighted hazard ratio [HR], 0.21; 95% confidence interval [CI], 0.09-0.45), as well as of overall mortality (weighted HR, 0.17; 95% CI, 0.06-0.45) and ischemic stroke/SE (weighted HR, 0.19; 95% CI, 0.06-0.60) with no significant increase of major bleeding in comparison with patients receiving no antithrombotics. In the subgroup of patients with atrial fibrillation, OACs resumption was also associated with a reduction of the primary end-point (weighted HR, 0.22; 95% CI, 0.09-0.54), and the secondary end-point ischemic stroke/SE (weighted HR, 0.09; 95% CI, 0.02-0.40). In conclusion, in patients who have an ICH while receiving warfarin, resuming anticoagulation results in a favorable trade-off between bleeding susceptibility and thromboembolic risk.

    Full Text Available Background and Purpose: Intracerebral hemorrhage (ICH constitutes now 52% of all strokes. Despite of its deadly pattern, locally there is no clinical grading scale for ICH-related mortality prediction. The first objective of this study was to develop a risk stratification scale (Kinshasa ICH score by assessing the strength of independent predictors and their association with in-hospital 30-day mortality. The second objective of the study was to create a specific local and African model for ICH prognosis. Materials and Methods: Age, sex, hypertension, type 2 diabetes mellitus (T2DM, smoking, alcohol intake, and neuroimaging data from CT scan (ICH volume, Midline shift of patients admitted with primary ICH and follow-upped in 33 hospitals of Kinshasa, DR Congo, from 2005 to 2008, were analyzed using logistic regression models. Results: A total of 185 adults and known hypertensive patients (140 men and 45 women were examined. 30-day mortality rate was 35% (n=65. ICH volume>25 mL (OR=8 95% CI: 3.1-20.2; P 7 mm, a consequence of ICH volume, was also a significant predictor of mortality. The Kinshasa ICH score was the sum of individual points assigned as follows: Presence of coma coded 2 (2 × 2 = 4, absence of coma coded 1 (1 × 2 = 2, ICH volume>25 mL coded 2 (2 × 2=4, ICH volume of ≤25 mL coded 1(1 × 2=2, left hemispheric site of ICH coded 2 (2 × 1=2, and right hemispheric site of hemorrhage coded 1(1 × 1 = 1. All patients with Kinshasa ICH score ≤7 survived and the patients with a score >7 died. In considering sex influence (Model 3, points were allowed as follows: Presence of coma (2 × 3 = 6, absence of coma (1 × 3 = 3, men (2 × 2 = 4, women (1 × 2 = 2, midline shift ≤7 mm (1 × 3 = 3, and midline shift >7 mm (2 × 3 = 6. Patients who died had the Kinshasa ICH score ≥16. Conclusion: In this study, the Kinshasa ICH score seems to be an accurate method for distinguishing those ICH patients who need continuous and special management

    Sneddon's syndrome is characterized by livedo reticularis and multiple ischemic infarcts often associated with antiphospholipid antibodies. Intracerebral hemorrhage (ICH) is unusual in Sneddon's syndrome and has not been reported as the presenting complaint. We report a 38-year-old woman with a history of two miscarriages, Raynaud's phenomenon and livedo reticularis who presented acutely with ICH. Angiography showed prominent leptomeningeal and transdural anastomoses (pseudoangiomatosis). Anticardiolipin antibodies were positive. A right frontal brain biopsy failed to reveal vasculitis and a skin biopsy was nonspecific. MRI showed residual intracerebral hemorrhage (ICH), diffuse atrophy, multiple small white matter infarcts and leptomeningeal enhancement. This is the first report of Sneddon's syndrome presenting with an ICH. It shares features with the Divry-van Bogaert syndrome. We discuss the cause of the pseudoangiomatosis pattern and its role in the genesis of the hemorrhage and suggest that cerebral angiography should be done in every patient with Sneddon's syndrome, as it could impact therapy.

    Symptomatic intracranial hemorrhage (sICH) is a serious complication of IV rt-PA therapy after acute ischemic stroke. Independent sICH predictors have been previously derived using case-control studies. Here we utilized a novel cohort-based comparison to identify additional independent predictors of sICH. We included 210 patients receiving IV rt-PA therapy from January 2009 through December 2013 at the Yale-New Haven Stroke Center. Clinical parameters were compared using Mann-Whitney tests, two-sample tests of proportions and two-sample t tests. Logistic regression was performed using sICH as the dependent variable. Predictive ability was assessed using areas under the receiver operating characteristic (ROC) curve. sICH rates were lowest from 2010 to 2012 and comprised the low sICH cohort (2.0 % sICH), compared to the high sICH cohort from 2009 to 2013 (9.2 % sICH, P = 0.025). Patients in the low sICH cohort had significantly more visual field deficits (38.6 vs. 24.8 %, P = 0.03) and decreased levels of consciousness (62.4 vs. 39.4 %, P vs. 13.8 %, P = 0.03) and early CT hypodensities (14.9 vs. 29.4 %, P = 0.01). These four parameters together predicted sICH modestly (area under ROC curve 0.66, odds ratio 2.72, P = 0.03) CONCLUSIONS: Using a novel cohort-based approach, we identified two new independent predictors of sICH after IV rt-PA therapy: the presence of the hyperdense MCA sign and early CT hypodensities. Novel methods are needed to reduce the risk of sICH for patients receiving antithrombolytic therapy for ischemic stroke.

  1. Use of therapeutic surfactant lavage in a preterm infant with massive pulmonary hemorrhage

    Full Text Available We report a case of a premature infant presenting with recurrent pulmonary hemorrhage in which we performed a therapeutic lavage with diluted surfactant after an acute episode of bleeding with severe intractable hypoxemia. Repeated small aliquots of diluted surfactant (10x2 mL allowed rapid improvement in oxygenation and reduction of required mean airway pressures during high frequency oscillatory ventilation. This observation may suggest that surfactant lavage could be beneficial in massive pulmonary hemorrhage in infants. A randomized controlled trial might be needed to clarify the potential benefit of this therapeutic intervention on outcome of infants suffering from this life-threatening complication.

    Early intensive blood pressure (BP) lowering has been shown to improve functional outcome in acute intracerebral hemorrhage (ICH), but the treatment effect is modest and without a clearly defined underlying explanatory mechanism. We aimed at more reliably quantifying the benefits of this treatment according to different time periods in the recovery of participants in the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT) studies. Pooled analysis of the pilot INTERACT1 (n = 404) and main INTERACT2 (n = 2,839) involving patients with spontaneous ICH (patient characteristic subgroups, with trends favoring those randomized early, and with higher SBP and milder neurological severity at baseline. Intensive BP lowering provides beneficial effects on physical functioning that manifests consistently through the early and later phases of recovery from ICH. © 2015 S. Karger AG, Basel.

    Thymic enlargement is a common and physiological finding in children and neonates' X-rays, but it is usually asymptomatic. Occasionally it can cause respiratory distress. In most cases the aetiology of this expansion remains unclear and it is diagnosed as a thymic hyperplasia. True thymic hyperplasia is defined as a gland expansion, both in size and weight, while maintaining normal microscopic architecture. Often it is a diagnosis of exclusion and prognosis is good. Thymic haemorrhage is an unusual condition related to high foetal and neonatal mortality. We report a case of spontaneous massive thymic haemorrhage in a newborn developing at birth acute respiratory distress associated with severe bilateral haemothorax. Thymic enlargement was evident after pleural evacuation and confirmed by radiographic, Computed Tomography (CT) images and Magnetic Resonance Imaging (MRI) sequences. The spontaneous resolution of this enlargement seen with CT scan and MRI sequences suggested a thymic haemorrhage; surgery was not necessary. Thymic haemorrhage should be considered in newborn infants with pleural effusion, mediastinal space enlargement and Respiratory Distress.

    Massive fetomaternal hemorrhage resulting in profound anemia and shock is associated with high perinatal morbidity and mortality. Although diagnosis before delivery is difficult, the clinical index of suspicion rises when a woman presents with history of decreased or absent fetal movements and antenatal monitoring shows a sinusoidal rhythm strip. The diagnosis can be made quickly by demonstration of fetal red blood cells in the maternal circulation and there is consistent recommendation in the literature to immediately order a Kleihauer-Betke test. Clinical manifestations of a fetomaternal hemorrhage depend on the volume of blood lost and the rate with which it occurred. The severely compromised anemic infant indicative of acute hemorrhage will be pale with gasping respirations and signs of circulatory shock. Immediate intervention with volume resuscitation is crucial for optimal outcome. This article describes a patient with massive fetomaternal hemorrhage and subsequent devastating neonatal complications. The focus of this article is to provide clinical guidance for the management and care of the infant affected by profound anemia.

    Full Text Available Vascular endothelial growth factor (VEGF has protective effects on many neurological diseases. However, whether VEGF acts on brain edema following intracerebral hemorrhage (ICH is largely unknown. Our previous study has shown aquaporin-4 (AQP4 plays an important role in brain edema elimination following ICH. Meanwhile, there is close relationship between VEGF and AQP4. In this study, we aimed to test effects of VEGF on brain edema following ICH and examine whether they were AQP4 dependent. Recombinant human VEGF165 (rhVEGF165 was injected intracerebroventricularly 1 d after ICH induced by microinjecting autologous whole blood into striatum. We detected perihemotomal AQP4 protein expression, then examined the effects of rhVEGF165 on perihemotomal brain edema at 1 d, 3 d, and 7 d after injection in wild type (AQP4(+/+ and AQP4 knock-out (AQP4(-/- mice. Furthermore, we assessed the possible signal transduction pathways activated by VEGF to regulate AQP4 expression via astrocyte cultures. We found perihemotomal AQP4 protein expression was highly increased by rhVEGF165. RhVEGF165 alleviated perihemotomal brain edema in AQP4(+/+ mice at each time point, but had no effect on AQP4(-/- mice. Perihemotomal EB extravasation was increased by rhVEGF165 in AQP4(-/- mice, but not AQP4(+/+ mice. RhVEGF165 reduced neurological deficits and increased Nissl's staining cells surrounding hemotoma in both types of mice and these effects were related to AQP4. RhVEGF165 up-regulated phospharylation of C-Jun amino-terminal kinase (p-JNK and extracellular signal-regulated kinase (p-ERK and AQP4 protein in cultured astrocytes. The latter was inhibited by JNK and ERK inhibitors. In conclusion, VEGF reduces neurological deficits, brain edema, and neuronal death surrounding hemotoma but has no influence on BBB permeability. These effects are closely related to AQP4 up-regulation, possibly through activating JNK and ERK pathways. The current study may present new insights to

    2012-03-01

    Full Text Available Abstract Background Inflammatory injury plays a critical role in intracerebral hemorrhage (ICH-induced neurological deficits; however, the signaling pathways are not apparent by which the upstream cellular events trigger innate immune and inflammatory responses that contribute to neurological impairments. Toll-like receptor 4 (TLR4 plays a role in inflammatory damage caused by brain disorders. Methods In this study, we investigate the role of TLR4 signaling in ICH-induced inflammation. In the ICH model, a significant upregulation of TLR4 expression in reactive microglia has been demonstrated using real-time RT-PCR. Activation of microglia was detected by immunohistochemistry, cytokines were measured by ELISA, MyD88, TRIF and NF-κB were measured by Western blot and EMSA, animal behavior was evaluated by animal behavioristics. Results Compared to WT mice, TLR4−/− mice had restrained ICH-induced brain damage showing in reduced cerebral edema and lower neurological deficit scores. Quantification of cytokines including IL-6, TNF-α and IL-1β and assessment of macrophage infiltration in perihematoma tissues from TLR4−/−, MyD88−/− and TRIF−/− mice showed attenuated inflammatory damage after ICH. TLR4−/− mice also exhibited reduced MyD88 and TRIF expression which was accompanied by decreased NF-κB activity. This suggests that after ICH both MyD88 and TRIF pathways might be involved in TLR4-mediated inflammatory injury possibly via NF-κB activation. Exogenous hemin administration significantly increased TLR4 expression and microglial activation in cultures and also exacerbated brain injury in WT mice but not in TLR4−/− mice. Anti-TLR4 antibody administration suppressed hemin-induced microglial activation in cultures and in the mice model of ICH. Conclusions Our findings suggest that heme potentiates microglial activation via TLR4, in turn inducing NF-κB activation via the MyD88/TRIF signaling pathway, and ultimately

    Objective: To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods: During the period of June 1998-Apr. 2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent transarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results: The interventional managements were successfully performed in all the 31 patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypophysin infusion group and embolization group were 69.2% (9/ 13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion: Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one,as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice. (authors)

    Emergent superselective embolization with a 3.0 F (1 mm) coaxial catheter and a steerable guidewire was performed in 27 patients with massive hemorrhage from a small-caliber splanchnic artery. Eight patients had intraperitoneal hemorrhage, 3 had hemobilia, 9 had gastric hemorrhage, and 7 had intestinal hemorrhage. Out of 27 patients, 7 had hemorrhage from a splanchnic artery pseudoaneurysm. Complete cessation of bleeding was obtained in all patients initially, but in 3 patients gastric hemorrhage recurred later. Otherwise, there was no rebleeding nor any major complication such as marked infarction of tissue or misplacement of embolic materials. This coaxial catheter system was highly reliable for achieving superselective catheterization in small-caliber arteries, minimizing the volume of infarcted tissue and allowing maximal preservation of splanchnic organic function. We conclude that this system represents a major advance in interventional radiology. (orig.)

    Full Text Available C1q/tumor necrosis factor-related protein-3 (CTRP3 is a recently discovered adiponectin paralog with established metabolic regulatory properties. However, the role of CTRP3 in intracerebral hemorrhage (ICH is still mostly unresolved. The aim of the present report was to explore the possible neuroprotective effect of CTRP3 in an ICH rat model and to elucidate the fundamental mechanisms. ICH was induced in rats by intracerebral infusion of autologous arterial blood. The effects of exogenous CTRP3 (recombinant or lentivirus CTRP3 on brain injury were explored on day 7. Treatment with CTRP3 reduced brain edema, protected against disruption of the blood-brain barrier, improved neurological functions, and promoted angiogenesis. Furthermore, CTRP3 greatly intensified phosphorylation of AMP-activated protein kinase (AMPK in addition to expression of hypoxia inducing factor-1α (HIF-1α and vascular endothelial growth factor (VEGF. Finally, the protective effects of CTRP3 could be blocked by either AMPK or VEGF inhibitors. Our findings give the first evidence that CTRP3 is a new proangiogenic and neuroprotective adipokine, which may exert its protective effects at least partly through an AMPK/HIF-1α/ VEGF-dependent pathway, and suggest that CTRP3 may provide a new therapeutic strategy for ICH.

    The ABC/2 method for calculating intracerebral hemorrhage (ICH) volume has been well validated. However, the formula, derived from the volume of an ellipse, assumes the shape of ICH is elliptical. We sought to compare the agreement of the ABC/2 formula with other methods through retrospective analysis of a selection of the STICH II cohort (Early Surgery Versus Initial Conservative Treatment in Patients With Spontaneous Supratentorial Lobar Intracerebral Haematomas). From 390 patients, 739 scans were selected from the STICH II image archive based on the availability of a CT scan compatible with OsiriX DICOM viewer. ICH volumes were calculated by the reference standard semiautomatic segmentation in OsiriX software and compared with calculated arithmetic methods (ABC/2, ABC/2.4, ABC/3, and 2/3SC) volumes. Volumes were compared by difference plots for specific groups: randomization ICH (n=374), 3- to 7-day postsurgical ICH (n=206), antithrombotic-associated ICH (n=79), irregular-shape ICH (n=703) and irregular-density ICH (n=650). Density and shape were measured by the Barras ordinal shape and density groups (1-5). The ABC/2.4 method had the closest agreement to the semiautomatic segmentation volume in all groups, except for the 3- to 7-day postsurgical ICH group where the ABC/3 method was superior. Although the ABC/2 formula for calculating elliptical ICH is well validated, it must be used with caution in ICH scans where the elliptical shape of ICH is a false assumption. We validated the adjustment of the ABC/2.4 method in randomization, antithrombotic-associated, heterogeneous-density, and irregular-shape ICH. URL: http://www.isrctn.com/ISRCTN22153967.

    The ABC/2 score estimates intracerebral hemorrhage (ICH) volume, yet validations have been limited by small samples and inappropriate outcome measures. We determined accuracy of the ABC/2 score calculated at a specialized reading center (RC-ABC) or local site (site-ABC) versus the reference-standard computed tomography-based planimetry (CTP). In Minimally Invasive Surgery Plus Recombinant Tissue-Type Plasminogen Activator for Intracerebral Hemorrhage Evacuation-II (MISTIE-II), Clot Lysis Evaluation of Accelerated Resolution of Intraventricular Hemorrhage (CLEAR-IVH) and CLEAR-III trials. ICH volume was prospectively calculated by CTP, RC-ABC, and site-ABC. Agreement between CTP and ABC/2 was defined as an absolute difference up to 5 mL and relative difference within 20%. Determinants of ABC/2 accuracy were assessed by logistic regression. In 4369 scans from 507 patients, CTP was more strongly correlated with RC-ABC (r(2)=0.93) than with site-ABC (r(2)=0.87). Although RC-ABC overestimated CTP-based volume on average (RC-ABC, 15.2 cm(3); CTP, 12.7 cm3), agreement was reasonable when categorized into mild, moderate, and severe ICH (κ=0.75; PABC (84% within 5 mL; 48% of scans within 20%) than for site-ABC (81% within 5 mL; 41% within 20%). RC-ABC had moderate accuracy for detecting ≥5 mL change in CTP volume between consecutive scans (sensitivity, 0.76; specificity, 0.86) and was more accurate with smaller ICH, thalamic hemorrhage, and homogeneous clots. ABC/2 scores at local or central sites are sufficiently accurate to categorize ICH volume and assess eligibility for the CLEAR-III and MISTIE III studies and moderately accurate for change in ICH volume. However, accuracy decreases with large, irregular, or lobar clots. URL: http://www.clinicaltrials.gov.

    In clinical research, massive transfusion (MT) is commonly defined as transfusion of 10 or more red blood cell (RBC) units within 24 hours. However, the clinical relevance of this definition remains poorly understood. In this study, we evaluated whether patients who reach the MT threshold during hemorrhage control differ clinically from those who reach it after hemorrhage control (i.e., after intensive care unit [ICU] arrival) but before 24 hours. Prospective data were collected on all Level I trauma resuscitations within 5.5 years. Patients transfused 10 or more RBCs in the first 24 hours of hospitalization were identified and stratified according to when the MT threshold was achieved: before ICU arrival (Pre-ICU) versus after ICU arrival but before 24 hours of hospitalization (Post-ICU). Clinical characteristics between groups were compared. Three hundred five patients received 10 or more units before ICU arrival, and 46 reached the MT threshold after ICU arrival but before 24 hours. Both groups were clinically similar with respect to age, sex, and Injury Severity Score, but the Post-ICU group had a larger proportion of blunt injuries (71 vs. 53%, p definition. However, they have a significantly decreased mortality risk at 24 hours and the potential to dilute the study cohort. For research purposes, restricting the MT definition to 10 or more RBCs during hemorrhage control may result in study cohorts with relatively more uniform mortality risks.

    Full Text Available Massive premacular hemorrhage can cause sudden visual loss. We sought to evaluate the efficacy, safety and visual outcome of nonvitrectomizing vitreous surgery with intravitreal tissue plasminogen activator (t-pa for long-lasting thick premacular hemorrhage. This retrospective, interventional study examined three consecutive eyes of three patients who received nonvitrectomizing vitreous surgery with intravitreal t-pa for the treatment of non-recent massive premacular hemorrhage. Detailed ophthalmoscopic examinations were performed pre- and postoperatively to evaluate the visual outcome, the resolution of premacular hemorrhage and the changes in lenticular opacity.In all three eyes, the premacular hemorrhage cleared after the procedure. Final best-corrected visual acuities improved from 6/30 to 6/10 in patient 1, 2/60 to 6/4 in patient 2, and 3/60 to 6/6 in patient 3. Operated and fellow eyes did not differ in terms of nuclear sclerosis. No complications from the procedure were noted.In these selected cases, nonvitrectomizing vitreous surgery with intravitreal t-pa was an effective and safe alternative treatment for non-recent massive premacular hemorrhage.

    Full Text Available Sea turtles are threatened to the point of extinction. The major goal of rehabilitating injured individuals is to eventually reintroduce them back into their habitat. Sea turtles are vulnerable to anthropogenic effects, and impact traumas are a common cause of death among these animals. Carapace and skull fractures are usually related to vessel collisions or propeller impacts. However, intentional traumas inflicted by humans are also considered as a potential threat. The purpose of this article is to describe the diagnosis and rehabilitation procedures of a juvenile green turtle (Chelonia mydas after severe head trauma with brain hemorrhage. The data presented here can be used as a reference for future cases of head trauma in chelonians.Tartarugas marinhas são animais ameaçados de extinção. Por isso, o principal objetivo em reabilitar indivíduos feridos é posteriormente reintroduzi-los em seu habitat. Quelônios marinhos apresentam grande vulnerabilidade a efeitos antropogênicos, e a ocorrência de traumatismos impactantes constituem uma importante causa de óbitos entre esses animais. Fraturas de carapaça e crânio estão normalmente associadas a colisões por embarcações. No entanto, lesões intencionais provocadas por humanos também podem ser consideradas ameaças em potencial. O objetivo deste estudo é descrever o diagnóstico e a reabilitação de um indivíduo jovem de tartaruga verde (C. mydas após traumatismo craniano severo com hemorragia cerebral.

    Intracerebral hemorrhagic stroke (ICH) causes high mortality and morbidity with very limited treatment options. Cell-based therapy has emerged as a novel approach to replace damaged brain tissues and promote regenerative processes. In this study we tested the hypothesis that intranasally delivered hypoxia-preconditioned BMSCs could reach the brain, promote tissue repair and improve functional recovery after ICH. Hemorrhagic stroke was induced in adult C57/B6 mice by injection of collagenase IV into the striatum. Animals were randomly divided into three groups: sham group, intranasal BMSC treatment group, and vehicle treatment group. BMSCs were pre-treated with hypoxic preconditioning (HP) and pre-labeled with Hoechst before transplantation. Behavior tests, including the mNSS score, rotarod test, adhesive removal test, and locomotor function evaluation were performed at varying days, up to 21days, after ICH to evaluate the therapeutic effects of BMSC transplantation. Western blots and immunohistochemistry were performed to analyze the neurotrophic effects. Intranasally delivered HP-BMSCs were identified in peri-injury regions. NeuN+/BrdU+ co-labeled cells were markedly increased around the hematoma region, and growth factors, including BDNF, GDNF, and VEGF were significantly upregulated in the ICH brain after BMSC treatment. The BMSC treatment group showed significant improvement in behavioral performance compared with the vehicle group. Our data also showed that intranasally delivered HP-BMSCs migrated to peri-injury regions and provided growth factors to increase neurogenesis after ICH. We conclude that intranasal administration of BMSC is an effective treatment for ICH, and that it enhanced neuroregenerative effects and promoted neurological functional recovery after ICH. Overall, the investigation supports the potential therapeutic strategy for BMSC transplantation therapy against hemorrhagic stroke. Copyright © 2015 Elsevier Inc. All rights reserved.

    Fetomaternal hemorrhage (FMH), which can occur throughout pregnancy, is still a poorly understood clinical condition. It is very difficult to be timely diagnosed and often results in poor pregnancy outcomes. Here the authors reported two rare cases of silent massive FMH of unknown cause in the third trimester of pregnancy, which presented with non-reactive fetal heart rhythm or decreased fetal movement at the very beginning, and resulted in severe fetal anemia and neonatal deaths. A pregnant woman at late pregnancy with a com- plain of unspecific signs such as decreased fetal movement should arouse a high index of clinical suspicion of idiopathic FMH, and an urgent ultrasound or lab tests detecting FMH could be suggested. Considering emergent delivery versus expectantly management will de- pend upon acute or chronic FMH, gestational age, results of fetal testing, availability of experienced personnel, and procedural difficulty.

A 29 year old woman with history of a Whipple procedure for pancreatic cancer and nonalcoholic steatohepatitis cirrhosis presented with a massive upper gastrointestinal bleeding (UGIB likely from esophageal varices and developed hemorrhagic shock. Emergent upper endoscopy could not be performed due to hemodynamic instability. Therefore, a Minnesota Tube was placed emergently for balloon tamponade of the bleeding. A transjugular intrahepatic portosystemic shunt was also placed emergently to decrease bleeding by reducing portal pressure. By this time, the patient had received 4 liters of normal saline, 14 units of packed red blood cells, 6 units of platelets, and 4 units of fresh frozen plasma. The Minnesota tube did control the bleeding somewhat, however, there was continued bloody drainage from the stomach port of the Minnesota tube. The patient’s abdomen became remarkably distended and was dull to percussion throughout. A CT scan of the abdomen and pelvis revealed severe dilatation of ...

  1. Use of Condom Tamponade to Manage Massive Obstetric Hemorrhage at a Tertiary Center in Rajasthan.

    Conventionally postpartum hemorrhage (PPH) has been defined as blood loss of more than 500 ml following vaginal delivery and 1000 ml following a cesarean section [Pritchard et al. in Am J Obstet Gynecol 84(10):1271-1282, (1962)]. Another definition labels PPH as any blood loss which causes a 10 % drop in hematocrit [Combs et al. in Obstet Gynecol 77:69-76, (1991)] or which threatens the hemodynamic stability of the patient and necessitates blood transfusion [Prendiville et al. in Cochrane Database Syst Rev 2:CD000007, (2000)]. The purpose of this study was to evaluate the effectiveness of condom tamponade in the management of massive obstetric hemorrhage. To evaluate the efficacy of a condom as a tamponade for intrauterine pressure to stop massive PPH. This prospective study was done in the Obstetrics and Gynecology Department of NIMS Medical College and Hospital, Jaipur, between December 2013 and February 2015. With aseptic precautions, a sterile rubber catheter fitted with a condom was introduced into the uterus. The condom was inflated with 250-500 ml normal saline according to need. Vaginal bleeding was observed, and further inflation was stopped when bleeding ceased. In all but 2 (94.44 %) the cases, postpartum bleeding was stopped within 10 min of creation of tamponade. On an average, 350 ml of normal saline was required to create adequate tamponade to stop the bleeding. Use of condom tamponade can effectively help in reducing both maternal morbidity and mortality associated with PPH. Our study encourages use of condom tamponade which is efficient, cost-effective, easily available and requires lesser skills as compared to the traditional surgical procedures.

    Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

    In patients with spontaneous intracerebral hemorrhage (sICH), hematoma expansion (HE) is associated with poor outcome. Spot sign and black hole sign are neuroimaging predictors for HE. This study was aimed to compare the predictive value of two signs for HE. Within 6 h after onset of sICH, patients were screened for the computed tomography angiography spot sign and the non-contrast computed tomography black hole sign. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of two signs for HE prediction were calculated. The accuracy of two signs in predicting HE was analyzed by receiver-operator analysis. A total of 129 patients were included in this study. Spot sign was identified in 30 (23.3%) patients and black hole sign in 29 (22.5%) patients, respectively. Of 32 patients with HE, spot sign was observed in 19 (59.4%) and black hole sign was found in 14 (43.8%). The occurrence of black hole sign was significantly associated with spot sign (P black hole sign for predicting HE were 43.75, 84.54, 48.28, and 82.00%, respectively. The area under the curve was 0.740 for spot sign and 0.641 for black hole sign. (P = 0.228) Both spot sign and black hole sign appeared to have good predictive value for HE, and spot sign seemed to be a better predictor.

    To investigate the combined effect of transcranial direct current stimulation (tDCS) and home-based occupational therapy on activities of daily living (ADL) and grip strength, in patients with upper limb motor impairment following intracerebral hemorrhage (ICH). A double-blind randomized controlled trial with one-week follow-up. Patients received five consecutive days of occupational therapy at home, combined with either anodal (n = 8) or sham (n = 7) tDCS. The primary outcome was ADL performance, which was assessed with the Jebsen-Taylor test (JTT). Both groups improved JTT over time (p occupational therapy provided greater improvements in grip strength compared with occupational therapy alone. tDCS is a promising add-on intervention regarding training of upper limb motor impairment. It is well tolerated by patients and can easily be applied for home-based training. Larger studies with long-term follow-up are needed to further explore possible effects of tDCS in patients with ICH. Five consecutive days of tDCS combined with occupational therapy provided greater improvements in grip strength compared with occupational therapy alone. tDCS is well tolerated by patients and can easily be applied for home-based rehabilitation.

    Full Text Available Intracerebral hemorrhage (ICH is a critical disease, highly associated with mortality and morbidity. Several studies have demonstrated the beneficial effect of mesenchymal stem cells (MSCs on ICH, mostly focused on their mid-to-long-term effect. Acute hematoma expansion is one of the most important prognostic factors of ICH. We hypothesized that MSCs would decrease mortality and hematoma size in acute ICH, based on the findings of a few recent researches reporting their effect on blood-brain barrier and endothelial integrity. Rat ICH models were made using bacterial collagenase. One hour after ICH induction, the rats were randomly divided into MSC-treated and control groups. Mortality, hematoma volume, ventricular enlargement, brain edema, and degenerating neuron count were compared at 24 hours after ICH induction. Expression of tight junction proteins (ZO-1, occludin and coagulation factor VII mRNA was also compared. Mortality rate (50% versus 8.3%, hematoma size, ventricular size, hemispheric enlargement, and degenerating neuron count were significantly lower in the MSC-treated group (p=0.034, 0.038, 0.001, 0.022, and <0.001, resp., while the expression of ZO-1 and occludin was higher (p=0.007 and 0.012. Administration of MSCs may prevent hematoma expansion in the hyperacute stage of ICH and decrease acute mortality by enhancing the endothelial integrity of cerebral vasculature.

    Spontaneous intracerebral hemorrhage (sICH) has a high mortality rate. Research has demonstrated that the occurrence of sICH is related to air pollution. This study used big data analysis to explore the impact of air pollution on the risk of sICH in patients of differing age and geographic location. 39,053 cases were included in this study; 14,041 in the Taipei region (Taipei City and New Taipei City), 5537 in Taoyuan City, 7654 in Taichung City, 4739 in Tainan City, and 7082 in Kaohsiung City. The results of correlation analysis indicated that there were two pollutants groups, the CO and NO₂ group and the PM 2.5 and PM 10 group. Furthermore, variations in the correlations of sICH with air pollutants were identified in different age groups. The co-factors of the influence of air pollutants in the different age groups were explored using regression analysis. This study integrated Taiwan National Health Insurance data and air pollution data to explore the risk factors of sICH using big data analytics. We found that PM 2.5 and PM 10 are very important risk factors for sICH, and age is an important modulating factor that allows air pollutants to influence the incidence of sICH.

    2016-01-01

    Full Text Available Background. The definition of prolonged length of stay (LOS during acute care remains unclear among surgically and conservatively treated patients with intracerebral hemorrhage (ICH. Methods. Using a population-based quality assessment registry, we calculated change points in LOS for surgically and conservatively treated patients with ICH. The influence of comorbidities, baseline characteristics at admission, and in-hospital complications on prolonged LOS was evaluated in a multivariate model. Results. Overall, 13272 patients with ICH were included in the analysis. Surgical therapy of the hematoma was documented in 1405 (10.6% patients. Change points for LOS were 22 days (CI: 8, 22; CL 98% for surgically treated patients and 16 days (CI: 16, 16; CL: 99% for conservatively treated patients. Ventilation therapy was related to prolonged LOS in surgically (OR: 2.2, 95% CI: 1.5–3.1; P<0.001 and conservatively treated patients (OR: 2.5, 95% CI: 2.2–2.9; P<0.001. Two or more in-hospital complications in surgical patients (OR: 2.7, 95% CI: 2.1–3.5 and ≥1 in conservative patients (OR: 3.0, 95% CI: 2.7–3.3 were predictors of prolonged LOS. Conclusion. The definition of prolonged LOS after ICH could be useful for several aspects of quality management and research. Preventing in-hospital complications could decrease the number of patients with prolonged LOS.

    Full Text Available Introduction. Length of stay (LOS in the intensive care unit (ICU of spontaneous intracerebral hemorrhage (sICH patients is one of the most important issues. The disease severity, psychosocial factors, and institutional factors will influence the length of ICU stay. This study is used in the Taiwan National Health Insurance Research Database (NHIRD to define the threshold of a prolonged ICU stay in sICH patients. Methods. This research collected the demographic data of sICH patients in the NHIRD from 2005 to 2009. The threshold of prolonged ICU stay was calculated using change point analysis. Results. There were 1599 sICH patients included. A prolonged ICU stay was defined as being equal to or longer than 10 days. There were 436 prolonged ICU stay cases and 1163 nonprolonged cases. Conclusion. This study showed that the threshold of a prolonged ICU stay is a good indicator of hospital utilization in ICH patients. Different hospitals have their own different care strategies that can be identified with a prolonged ICU stay. This indicator can be improved using quality control methods such as complications prevention and efficiency of ICU bed management. Patients’ stay in ICUs and in hospitals will be shorter if integrated care systems are established.

    In this study, we examined the effects of motor skills training on the sensorimotor function and the expression of genes associated with synaptic plasticity after intracerebral hemorrhage (ICH) in rats. Male Wistar rats were subjected to ICH or sham operation. ICH was caused by the injection of collagenase into the left striatum. Rats were randomly assigned to no training, acrobatic training, and sham groups. The acrobatic group performed 5 types of acrobatic tasks from 4 to 28 days after surgery. The forelimb sensorimotor function was evaluated over time using forepaw grasping, forelimb placing, and postural instability tests. At 14 and 29 days after the lesion, we analyzed the mRNA expression levels of microtubule-associated protein 2 (MAP2), brain-derived neurotrophic factor, and growth-associated protein 43 in the bilateral sensorimotor cortex (forelimb area) by real-time reverse transcription-polymerase chain reaction. Motor skills training in ICH rats improved the sensorimotor dysfunction significantly from the early phase. The mRNA expression level of MAP2 was upregulated in the ipsilesional sensorimotor cortex by motor skills training at 29 days after the lesion. Our results suggest that sensorimotor functional recovery following motor skills training after ICH is promoted by dendritic growth in the ipsilesional sensorimotor cortex.

    Full Text Available Spontaneous intracerebral hemorrhage (ICH is a devastating stroke subtype. Matrix metalloproteinases (MMPs function in the degradation of extracellular matrix and the activities of MMPs are modulated by their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs. This study aimed to discuss relationship of MMP-2 and TIMP-2 to spontaneous deep ICH (SDICH susceptibility and hematoma size.Associations were tested by logistic regression and general linear models (GLM where appropriate, adjusting with covariables of age, sex, hypertension, diabetes mellitus, smoking, and alcohol consumption. Association analyses were performed first by stratification of genders and then by the age of 65 years old (y/o. Elder population was defined as subjects who were older than 65 y/o.There were 396 SDICH patients and 376 control subjects in this study.

    Hemorrhage is a leading cause of maternal morbidity and mortality worldwide. It is especially difficult to treat in patients of the Jehovah's Witness faith because they refuse certain blood products. This case report describes the resuscitation of a parturient Jehovah's Witness whose postcesarean delivery course was complicated by massive hemorrhage from unrecognized arterial bleeding in the intensive care unit with significant hemodynamic instability that necessitated an emergency bedside laparotomy. Her hemoglobin nadir was 1.5 mg/dL. The case demonstrates the key place of preprocedure planning, blood conservation, and coagulation factor management in this specific patient population.

    To report the outcomes of vitreous hemorrhage (VH) associated with hemorrhagic polypoidal choroidal vasculopathy (PCV). A retrospective study of 28 eyes of 27 consecutive patients of hemorrhagic PCV with VH, which were managed surgically between January 2003 and December 2011, was performed. All patients underwent pars plana vitrectomy for VH associated with PCV. The main outcome measure was best-corrected visual acuity (BCVA) at baseline, at 1, 3 and 6 months post operatively and at last follow up. The visual acuity measured on early treatment diabetic retinopathy study (ETDRS) chart improved in 16 eyes (57.1 %) by two or more lines, remained unchanged in nine eyes (32.1 %) and decreased in three (10.7 %) after surgery when compared to baseline VA. The mean baseline VA was 2.69 ± 0.57 logMAR units (hemorrhagic PCV have sustained improvement in visual acuity following surgery.

    Objective: To investigate the clinical application of bilateral uterine arterial chemoembolization in treating massive hemorrhage due to uterine scar pregnancy after cesarean section. Methods: Sixteen patients with massive hemorrhage due to cesarean scar pregnancy were enrolled in the study, the mean blood loss was (2 200 ± 1 400) ml. With Seldinger technique, abdominal angiography by using a pig-tail catheter was carried out. When bilateral uterine arterial bleeding was confirmed, selective or super-selective catheterization was employed and bilateral uterine arterial chemoembolization with infusion of 5-Fu or methotrexate (MTX) together with gelatin sponge via the catheters was conducted. The clinical results were observed. Results: The technical success was achieved in all 16 patients. No recurrent bleeding occurred during a follow-up of 3-6 months. Conclusion: The emergency bilateral uterine arterial chemoembolization is a safe and effective treatment for massive hemorrhage due to cesarean scar pregnancy with no serious complications, therefore, this technique is worth being used in clinical practice.

    To investigate the association between single nucleotide polymorphisms or haplotypes of the COL4A1 gene and the risk of intracerebral hemorrhage (ICH). We conducted a case-control study that included 181 patients from the Chinese Han population with hypertensive ICH and 197 hypertension patients without ICH. Genomic DNA was extracted by DNA extraction kit, and the 6 single nucleotide polymorphism genotypes of the COL4A1 gene were detected with a MassARRAY Analyzer. Unphased 3.1.4 and SPSS 19.0 were used to analyze the association between alleles, genotypes, and haplotypes of the COL4A1 gene and the risk of ICH. Compared with the control group, patients in the ICH group were significantly younger. There were no differences in gender, diabetes, hyperlipidemia, current smoking, and alcohol consumption between the 2 groups. Our association analysis showed that the rs3742207 A, rs11069830 A, and rs679505 A alleles were association factors of the risks of ICH; rs11069830 AA, rs544012 AC, and rs679505 AA genotypes were association factors of the risk of ICH; AA haplotype (rs3742207-rs11069830) was an association factor of the risk of ICH. After adjusting age and gender by multivariate logistic regression, the rs544012 AC and rs679505 AA genotypes were independently associated with the risk of ICH. Our study showed that the rs544012 AC and rs679505 AA genotypes were independently associated with the risk of ICH in the Chinese Han population and that the AA haplotype (rs3742207-rs11069830) in the COL4A1 gene may be related to the risk of ICH in the Chinese Han population; these conclusions need further confirmation in future studies with larger samples.

    While oral anticoagulants (OACs) are highly effective for ischemic stroke prevention in atrial fibrillation, intracerebral hemorrhage (ICH) remains the most feared complication of OAC. Clinical controversy remains regarding OAC resumption and its timing for ICH survivors with atrial fibrillation because the balance between risks and benefits has not been investigated in randomized trials. To survey the practice of stroke neurologists, thrombosis experts and neurosurgeons on OAC re-initiation following OAC-associated ICH. An online survey was distributed to members of the International Society for Thrombosis and Haemostasis, Canadian Stroke Consortium, NAVIGATE-ESUS trial investigators (Clinicatrials.gov identifier NCT02313909) and American Association of Neurological Surgeons. Demographic factors and 11 clinical scenarios were included. Two hundred twenty-eight participants from 38 countries completed the survey. Majority of participants were affiliated with academic centers, and >20% managed more than 15 OAC-associated ICH patients/year. Proportion of respondents suggesting OAC anticoagulant resumption varied from 30% (for cerebral amyloid angiopathy) to 98% (for traumatic ICH). Within this group, there was wide distribution in response for timing of resumption: 21.4% preferred to re-start OACs after 1-3 weeks of incident ICH, while 25.3% opted to start after 1-3 months. Neurosurgery respondents preferred earlier OAC resumption compared to stroke neurologists or thrombosis experts in 5 scenarios (p<0.05 by Kendall's tau). Wide variations in current practice exist among management of OAC-associated ICH, with decisions influenced by patient- and provider-related factors. As these variations likely reflect the lack of high quality evidence, randomized trials are direly needed in this population.

    Intracerebral hemorrhage (ICH) is the most serious complication of oral anticoagulation. This study investigated the risk of ICH for phenprocoumon which is the most widely used oral anticoagulant in Germany. We conducted a nested case-control study in a cohort of 13.4 million insurants of 4 German statutory health insurances (SHIs) who were continuously enrolled for 6 months prior to cohort entry. Cases were patients hospitalized for ICH. Ten controls were matched to each case by SHI, birth year, and sex using incidence density sampling. Rate ratios (RR) of ICH for current phenprocoumon use as compared to non-use were estimated from odds ratios calculated by conditional logistic regression analyses considering multiple risk factors. Analysis of the full cohort revealed a strong increase in incidence of ICH with increasing age. In the nested case-control study including 8138 cases of ICH and 81,373 matched controls, we observed an increased risk of ICH for current phenprocoumon exposure that varied with age. The phenprocoumon-associated risk of ICH was lower in older age groups with RRs from 4.20 (95% confidence interval (CI) 2.44-7.21) for phenprocoumon users less than 55 years of age to 2.43 (95%CI, 1.81-3.27) for those older than 85 years. Our study confirmed known risk factors of ICH. Phenprocoumon exposure was associated with an increased risk of ICH. The interaction of risk for phenprocoumon with age was unexpected and needs further study. (c) 2010 John Wiley & Sons, Ltd.

    Intracerebral hemorrhage (ICH) is a detrimental type of stroke. Mouse models of ICH, induced by collagenase or blood infusion, commonly target striatum, but not other brain sites such as ventricular system, cortex, and hippocampus. Few studies have systemically investigated brain damage and neurobehavioral deficits that develop in animal models of ICH in these areas of the right hemisphere. Therefore, we evaluated the brain damage and neurobehavioral dysfunction associated with right hemispheric ICH in ventricle, cortex, hippocampus, and striatum. The ICH model was induced by autologous whole blood or collagenase VII-S (0.075 units in 0.5 µl saline) injection. At different time points after ICH induction, mice were assessed for brain tissue damage and neurobehavioral deficits. Sham control mice were used for comparison. We found that ICH location influenced features of brain damage, microglia/macrophage activation, and behavioral deficits. Furthermore, the 24-point neurologic deficit scoring system was most sensitive for evaluating locomotor abnormalities in all four models, especially on days 1, 3, and 7 post-ICH. The wire-hanging test was useful for evaluating locomotor abnormalities in models of striatal, intraventricular, and cortical ICH. The cylinder test identified locomotor abnormalities only in the striatal ICH model. The novel object recognition test was effective for evaluating recognition memory dysfunction in all models except for striatal ICH. The tail suspension test, forced swim test, and sucrose preference test were effective for evaluating emotional abnormality in all four models but did not correlate with severity of brain damage. These results will help to inform future preclinical studies of ICH outcomes. Copyright © 2018 Elsevier Inc. All rights reserved.

    To describe the signal void dots found on T2-weighted magnetic resonance (MR) images of the brain in hypertensive patients. Conventional T2-weighted MR images of 11 patients with hypertensive intracerebral hemorrhage (ICH), 14 with lacunar infarction and 11 comprising a normal control group aged over 60 were analyzed with regard to the presence, location, number and size of signal void dots. We also evaluated their relationship to hypertension. We performed time-of-flight or phase contrast MR angiography, gradient echo pulse sequences, or conventional cerebral angiography in some hypertensive ICH patients and compared them with corresponding T2-weighted images. Signal void dots were found in all patients with hypertensive ICH. Six of 14 patients with lacunar infarction showed these dots;all six suffered from hypertension. The dots were located in the thalami, pons and basal ganglia, and were measured as 1 to 4mm in diameter, mostly 2mm;they looked larger on gradient echo images. In the normal control group there were no signal void dots, and on MR or conventional angiography, no vascular ectasia was noted at the site corresponding to the signal void dots. Signal void dots were not considered to be part of the normal aging process, but appeared to be closely related to hypertension and ICH. The dots were thought to be due to the susceptibility effect of blood degradation product rather than to flow artifact or enlarged vessels. The thrombosed microaneurysm with or without surrounding microleakage of blood may explain the nature of signal void dots on T2-weighted images of hypertensive brain

    Rehabilitative approaches benefit motor functional recovery after stroke and relate to neuronal plasticity. We investigated the effects of a treadmill running exercise on the motor functional recovery and neuronal plasticity after collagenase-induced striatal intracerebral hemorrhage (ICH) in rats. Male Wistar rats were injected with type IV collagenase into the left striatum to induce ICH. Sham-operated animals were injected with saline instead of collagenase. The animals were randomly assigned to the sham control (SC), the sham exercise (SE), the ICH control (IC), or the ICH exercise (IE) group. The exercise groups were forced to run on a treadmill at a speed of 9 m/min for 30 min/day between days 4 and 14 after surgery. Behavioral tests were performed using a motor deficit score, a beam-walking test and a cylinder test. At fifteen days after surgery, the animals were sacrificed, and their brains were removed. The motor function of the IE group significantly improved compared with the motor function of the IC group. No significant differences in cortical thickness were found between the groups. The IC group had fewer branches and shorter dendrite lengths compared with the sham groups. However, dendritic branches and lengths were not significantly different between the IE and the other groups. Tropomyosin-related kinase B (TrkB) expression levels increased in the IE compared with IC group, but no significant differences in other protein (brain-derived neurotrophic factor, BDNF; Nogo-A; Rho-A/Rho-associated protein kinase 2, ROCK2) expression levels were found between the groups. These results suggest that improved motor function after a treadmill running exercise after ICH may be related to the prevention of dendritic regression due to TrkB upregulation. Copyright © 2015.

    We investigated the effects of motor skills training on several types of motor function and synaptic plasticity following intracerebral hemorrhage (ICH) in rats. Male Wistar rats were injected with collagenase into the left striatum to induce ICH, and they were randomly assigned to the ICH or sham groups. Each group was divided into the motor skills training (acrobatic training) and control (no exercise) groups. The acrobatic group performed acrobatic training from 4 to 28 days after surgery. Motor functions were assessed by motor deficit score, the horizontal ladder test and the wide or narrow beam walking test at several time points after ICH. The number of ΔFosB-positive cells was counted using immunohistochemistry to examine neuronal activation, and the PSD95 protein levels were analyzed by Western blotting to examine synaptic plasticity in the bilateral sensorimotor cortices and striata at 14 and 29 days after ICH. Motor skills training following ICH significantly improved gross motor function in the early phase after ICH and skilled motor coordinated function in the late phase. The number of ΔFosB-positive cells in the contralateral sensorimotor cortex in the acrobatic group significantly increased compared to the control group. PSD95 protein expression in the motor cortex significantly increased in the late phase, and in the striatum, the protein level significantly increased in the early phase by motor skills training after ICH compared to no training after ICH. We demonstrated that motor skills training improved motor function after ICH in rats and enhanced the neural activity and synaptic plasticity in the striatum and sensorimotor cortex.

    Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

    Background Positive "dynamic spot sign" has been proven to be a potential risk factor for acute intracerebral hemorrhage (ICH) expansion, but local perfusion change has not been quantitatively investigated. Purpose To quantitatively evaluate perfusion changes at the ICH area using computed tomography perfusion (CTP) imaging. Material and Methods Fifty-three patients with spontaneous ICH were recruited. Unenhanced computed tomography (NCCT), CTP within 6 h, and follow-up NCCT were performed for 21 patients in the "spot sign"-positive group and 32 patients in the control group. Cerebral perfusion change was quantitatively measured on regional cerebral blood flow/regional cerebral blood volume (rCBF/rCBV) maps. Regions of interest (ROIs) were set at the "spot-sign" region and the whole hematoma area for "spot-sign"-positive cases, and at one of the highest values of three interested areas and the whole hematoma area for the control group. Hematoma expansion was determined by follow-up NCCT. Results For the "spot-sign"-positive group, the average rCBF (rCBV) values at the "spot-sign" region and the whole hematoma area were 21.34 ± 15.24 mL/min/100 g (21.64 ± 21.48 mL/100g) and 5.78 ± 6.32 mL/min/100 g (6.07 ± 5.45 mL/100g); for the control group, the average rCBF (rCBV) values at the interested area and whole hematoma area were 2.50 ± 1.83 mL/min/100 g (3.13 ± 1.96 mL/100g) and 3.02 ± 1.80 mL/min/100 g (3.40 ± 1.44 mL/100g), respectively. Average rCBF and rCBV values of the "spot-sign" region were significantly different from other regions ( P spot-sign"-positive and control groups were 25.24 ± 19.38 mL and -0.41 ± 1.34 mL, respectively. Conclusion The higher perfusion change at ICH on CTP images may reflect the contrast extravasation and be associated with the hematoma expansion.

    Hematoma expansion (HE) is a major determinant of a poor outcome in patients with a spontaneous intracerebral hemorrhage (sICH). The blend sign and the black hole sign are distinguished from non-contrast CT (NCCT) in patients with sICH, and both are independent neuroimaging predictors of HE. The purpose of the current study was to compare the value of the two signs in the prediction of HE. We retrospectively analyzed clinical and neuroimaging data from 228 patients with sICH who were treated at our hospital between August 2015 and September 2017. NCCT of the brain was performed upon admission (within 6 h of the onset of symptoms) to identify the blend sign and the black hole sign. HE was determined based on CT during a follow-up 24 h later. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with which the blend sign and the black hole sign predicted HE were calculated. Receiver operating characteristic (ROC) curve analysis was performed in order to compare the accuracy of the two signs in predicting HE. The blend sign was identified in 46 patients (20.2%) and the black hole sign was identified in 38 (16.7%) based on NCCT of the brain upon admission. Of the 65 patients with HE, the blend sign was noted in 28 and the black hole sign was noted in 22. The blend sign had a sensitivity of predicting HE of 43.1%, a specificity of 89.0%, a PPV of 60.9%, and an NPV of 79.7%. In contrast, the black hole sign had a sensitivity of predicting HE of 33.9%, a specificity of 90.2%, a PPV of 57.9%, and an NPV of 77.4%. The area under the ROC curve was 0.660 for the blend sign and 0.620 for the black hole sign (p = 0.516). In conclusion, the blend sign and the black hole sign on CT are both good predictors of HE in patients with sICH, though the blend sign seems to have a higher level of accuracy.

    To investigate parameters associated with hematoma enlargement in non-vitamin K antagonist oral anticoagulant (NOAC)-related intracerebral hemorrhage (ICH). This retrospective cohort study includes individual patient data for 190 patients with NOAC-associated ICH over a 5-year period (2011-2015) at 19 departments of neurology across Germany. Primary outcome was the association of prothrombin complex concentrate (PCC) administration with hematoma enlargement. Subanalyses were calculated for blood pressure management and its association with the primary outcome. Secondary outcomes include associations with in-hospital mortality and functional outcome at 3 months assessed using the modified Rankin Scale. The study population for analysis of primary and secondary outcomes consisted of 146 NOAC-ICH patients with available follow-up imaging. Hematoma enlargement occurred in 49/146 (33.6%) patients with NOAC-related ICH. Parameters associated with hematoma enlargement were blood pressure ≥ 160mmHg within 4 hours and-in the case of factor Xa inhibitor ICH-anti-Xa levels on admission. PCC administration prior to follow-up imaging was not significantly associated with a reduced rate of hematoma enlargement either in overall NOAC-related ICH or in patients with factor Xa inhibitor intake (NOAC: risk ratio [RR] = 1.150, 95% confidence interval [CI] = 0.632-2.090; factor Xa inhibitor: RR = 1.057, 95% CI = 0.565-1.977), regardless of PCC dosage given or time interval until imaging or treatment. Systolic blood pressure levels < 160mmHg within 4 hours after admission were significantly associated with a reduction in the proportion of patients with hematoma enlargement (RR = 0.598, 95% CI = 0.365-0.978). PCC administration had no effect on mortality and functional outcome either at discharge or at 3 months. In contrast to blood pressure control, PCC administration was not associated with a reduced rate of hematoma enlargement in NOAC-related ICH

    Patients with intracerebral hemorrhage (ICH) are at high risk for severe stress-related upper gastrointestinal (UGI) bleeding, which is predictive of higher mortality. The aim of this study was to evaluate the effectiveness of omeprazole and cimetidine compared with a placebo in the prevention and management of stress-related UGI bleeding in patients with ICH. In a single-center, randomized, placebo-controlled study, 184 surgically treated patients with CT-proven ICH within 72 hours of ictus and negative results for gastric occult blood testing were included. Of these patients, 165 who were qualified upon further evaluation were randomized into 3 groups: 58 patients received 40 mg intravenous omeprazole every 12 hours, 54 patients received 300 mg intravenous cimetidine every 6 hours, and 53 patients received a placebo. Patients whose gastric occult blood tests were positive at admission (n = 70) and during/after the prophylaxis procedure (n = 48) were treated with high-dose omeprazole at 80 mg bolus plus 8 mg/hr infusion for 3 days, followed by 40 mg intravenous omeprazole every 12 hours for 7 days. Of the 165 assessable patients, stress-related UGI bleeding occurred in 9 (15.5%) in the omeprazole group compared with 15 patients (27.8%) in the cimetidine group and 24 patients (45.3%) in the placebo group (p = 0.003). The occurrence of UGI bleeding was significantly related to death (p = 0.022). Nosocomial pneumonia occurred in 14 patients (24.1%) receiving omeprazole, 12 (22.2%) receiving cimetidine, and 8 (15.1%) receiving placebo (p > 0.05). In patients with UGI bleeding in which high-dose omeprazole was initiated, UGI bleeding arrested within the first 3 days in 103 patients (87.3%). Omeprazole significantly reduced the morbidity of stress-related UGI bleeding in patients with ICH due to its effective prophylactic effect without increasing the risk of nosocomial pneumonia, but it did not reduce the 1-month mortality or ICU stay.

    We studied the clinical features and CT findings of 20 cases with fulminant subarachonid hemorrhages in the acute stage. They were admitted to our hospital within 3 hours after the attack as DOA (dead on arrival) or near DOA. CT-visualized subarachnoid hemorrhages were located in the basal cisterns surrounding the brain stem in all cases. In 90 % of the cases, the subarachnoid hemorrhage formed a clot or a thick layer. Massive intracerebral hematomas were observed in 10 % of the cases. Acute intraventricular hemorrhages were seen in 80 % of the cases. The mechanism of intraventricular hemorrhage in 70 % of the cases was of the reflux type, which was characterized by a reflux of the severe subarachnoid hemorrhage in the basal cistern. Acute and diffuse brain swelling on CT scan was observed in several cases, which also showed initial increased intracranial pressures. The major mechanisms leading to acute death or a very severe state soon after subarachnoid hemorrhage might be caused by acute brain-stem failure due to severe subarachnoid hemorrhages in the basal cisterns surrounding the brain-stem and an acute increase in intracranial pressure by cerebral edema following subarachnoid hemorrhage and secondary cerebral ischemia due to cardiac and respiratory arrest.

    A sequential study with computerized tomography (CT scan) of two cases of traumatic intracerebral hematoma is reported. Case 1 was a 69-year-old man who had a head injury. The initial CT scan, taken 1 hour after his injury, showed a left temporal salt-and-pepper appearance, which proved to be a cerebral contusion. The CT scan 4.5 hours after his injury showed a left temporal high density area instead. An operation was performed, and a massive intracerebral hematoma was observed. Case 2 was a 61-year-old man who was also admitted because of a head injury. The initial CT scan, taken 1 hour after his injury, revealed several bifrontal intracerebral hemorrhagic spots in the low-density areas, suggesting contusion. A secondary CT scan (23 hours) demonstrated that the traumatic intracerebral hematoma had developed into a posttraumatic cerebral contusion. The operation disclosed a hematoma surrounded by contusion. These cases prove that traumatic intracerebral hematoma is often caused by cerebral contusion.

    A male infant delivered to a primipara woman following vacuum applications. He was vigorous at birth, with small caput and scalp bruising. His head was enlarging; he became pale with respiratory distress. Subgaleal hemorrhage (SGH) was suspected. His hematocrit was noted to be 26.2 percent prior to transfusion of O, Rh-negative blood (40 mL/kg). Moderate disseminated intravascular coagulation (DIC) was noted at 12 hours of age. Posttransfusion of fresh frozen plasma (FFP), his condition became stable, and DIC gradually resolved. Head magnetic resonance imaging did not show intracranial hemorrhage. Although one episode of seizures was noted, electroencephalogram was normal. With the application of obstetric vacuum, we recommend that the neonatal health care professionals frequently evaluate the infant's condition. In light of developing fluctuant subgaleal fluid associated with pallor, anemia, metabolic acidosis, and respiratory distress, immediate blood transfusion is warranted. In the presence of DIC, transfusion of FFP is beneficial.

    Full Text Available A case of massive post-partum hemorrhage in East-Malaysia, associated with 3-4 methylene-dioxy-methamphetamine (MDMA abuse otherwise known as Ecstasy or locally as “ICE”, injected by the patient as a means to suppress labor pains prior to hospital presentation. We report a rare case of substance abuse that lead to life threatening hemorrhage in a maternal patient of productive age group. Presenting to the labor suite in second stage of labor in breech presentation, exhibiting active neuropsychiatric symptoms of intoxication like euphoria, drowsiness, mydriasis but able to obey commands. A rapid response by the Obstetric on-call team proceeded with an assisted-breech delivery. Post-delivery, a baby girl with poor Apgar score was born and intubated. The mother was then posted for an Examination Under Anesthesia as she was noted to have slow blood oozing per-vaginally using a single shot spinal as she exhibited features of difficult intubation and high risk of aspiration. During the procedure, she tipped into massive PPH complicated with DIVC, and was rushed into the intensive care unit for stabilization and back into the operation theatre, needing a total abdominal hysterectomy (TAH as definitive bleeding control. She required large scale resuscitative efforts peri-operatively including continuous veno-venous hemofiltration (CVVH as well as regional intensive care consultation. We describe, chronologically the anesthetic challenges faced in managing a patient in acute substance intoxication at presentation to our district hospital during twilight hours. We then explain the pharmacodynamics of MDMA in provoking coagulopathy. No reports of similar cases in the South-East Asia region.

    Abnormal uterine bleeding and other gynecologic complications associated with a previous cesarean section scar are only recently being identified and described. Herein we report a rare case of a woman with recurring massive uterine bleeding after 2 cesarean sections. Curettage and hormone therapy were unsuccessfully used in an attempt to control the bleeding. After she was transferred to our hospital, she had another episode of vaginal bleeding that was successfully managed with oxytocin and hemostatic. Diagnostic hysteroscopy performed under anesthesia revealed an abnormal transected artery in the cesarean section scar with a thrombus visible. In the treatment at the beginning of laparoscopic management, we adopted temporary bilateral uterine artery occlusion with titanium clips to prevent massive hemorrhage. Secondly, with the aid of hysteroscopy, the bleeding site was opened, and then the cesarean scar was wedge resected and stitched interruptedly with 1-0 absorbable sutures. The postoperative recovery was uneventful. It would seem that the worldwide use of cesarean section delivery may contribute to the risk of gynecologic disturbances including some unrecognized and complex conditions as seen in this case.

    In 2007, "the Guidelines for Actions against Intraoperative Critical Hemorrhage" were established by the Japanese Society of Anaesthesiologists and the Japanese Society of Blood transfusion and Cell Therapy. The documentation of in-hospital procedures for critical hemorrhage, especially about how to select RBC units, has widely standardized hospital practice. Patients with intraoperative critical hemorrhage sometimes suffer from massive blood loss. In this situation, some patients develop coagulopathy. To treat them, we need to evaluate their coagulation status based on laboratory test results. So, we performed a nationwide questionnaire survey on the current status of hospital clinical laboratories evaluating critical hemorrhage. From the results of this survey, it was recommended that central hospital laboratories should try to reduce the turn-around time required to test for coagulation parameters as much as possible for appropriate substitution therapy.

    Full Text Available We present the case of a patient who had a large pseudocyst in the right adrenal gland, which was ruptured following blunt abdominal trauma, leading to a voluminous hemorrhage in retroperitoneum. A 29-year old female patient was admitted in the emergency room following a fall from stairs with trauma in right flank. She underwent a computerized tomography that evidenced a large retroperitoneal collection, with no apparent renal damage. She was submitted to surgery, where a large ruptured cyst was observed, originating from the upper portion of the right adrenal gland. Cystic diseases of adrenal gland are rare. Highly voluminous cysts can be damaged in cases of blunt trauma to the lumbar region leading to large hematomas in retroperitoneum.

    Full Text Available A 24-year-old male Navy soldier was struck on the left thigh by a ruptured cable and was subsequently thrown into the sea. Initial evaluation showed an Injury Severity Score of 34. Core body temperature was 34.1°C. Laboratory data included a hemoglobin level of 4.5 g/dL and a hematocrit of 13.3%. Prothrombin time was prolonged (>100 seconds, international normalized ratio was elevated (9.99, and partial thromboplastin time was elevated (>180 seconds. The patient was treated for hypothermia, coagulopathy, and metabolic acidosis during resuscitation. The patient was transfused with 16,320 mL of blood during the first 24 hours following the accident, including 4500 mL (18 units of warm fresh whole blood (WFWB donated by the patient's military colleagues. The patient was successfully resuscitated, and the injured leg was salvaged. Component therapy can afford replacement of specific deficiencies or requirements, decrease the risk of transfusion-transmitted infectious diseases, and improve resource utilization. However, a protocol of early transfusion with WFWB should be considered during resuscitation following massive hemorrhage in specific conditions such as battle fields or urgent situations.

    Mucormycosis is an invasive and aggressive opportunistic fungal infection that usually presents with rhinocerebral or pulmonary involvement and rarely involves the gastrointestinal tract. The disease is acute with mortality rate up to 100%. A 68-year-old male was undergoing treatment at a local hospital for COPD exacerbation with IV steroids and antibiotics. Two weeks into his treatment he suddenly developed massive upper GI bleeding and hemodynamic instability that necessitated transfer to our tertiary care hospital for further treatment and management. An urgent upper endoscopy revealed multiple large and deep gastric and duodenal bulb ulcers with stigmata of recent bleeding. The ulcers were treated endoscopically. Biopsies showed fibrinopurulent debris with fungal organisms. Stains highlighted slightly irregular hyphae with rare septa and yeast suspicious for Candida. The patient was subsequently placed on fluconazole. Unfortunately, the patient's general condition continued to worsen and he developed multiorgan failure and died. Autopsy revealed disseminated systemic mucormycosis. Most of the cases of gastrointestinal mucormycosis were reported from the tropics and few were reported in the United States. The disease occurs most frequently in immunocompromised individuals. The rare incidence of GI involvement, acute nature, severity and the problematic identification of the organisms on biopsies make antemortem diagnosis challenging. Treatment includes parenteral antifungals and debridement of the infected tissues. Gastroenterologists should be aware of this rare cause of gastrointestinal bleeding and understand the importance of communication with the reviewing pathologist so that appropriate, and often lifesaving, therapies can be administered in a timely manner.

    Computed tomography (CT) is the most accurate and reliable method for the diagnosis of intracerebral and intraventricular hemorrhage. The precise anatomic extent of the nematoma, associated cerebral edema, ventricular deformity and displacement, and hydrocephalus are all readily assessed. Aside from head trauma, the principal cause of intracerebral hematoma is hypertensive vascular disease. Although hematomas from various causes may present similar CT appearances frequently the correct etiology may be suggested by consideration of patient's age, clinical history, and the location of the hematoma. The analytical study was performed in 180 cases of intracerebral hemorrhages by CT from October 1981 to January 1983. The results were as follows; 1. The most prevalent age group was 6th decade (37.2%). Male was prevalent to female at the ration of 1.6 to 1. 2. The most common symptom and sign was mental disturbance (48.7%), motor weakness (23%), headache (10.6%), nausea and vomiting (9.8%). 3. The causes of hemorrhage were hypertension (53.9%), head trauma (30.6%), aneurysm (6.1%) and A-V malformation (7.2%). 4. The frequent locations of hemorrhage were basal ganglia and thalamus (40.4%), lobes (35%), ventricles (21.8%). 5. The distribution of hemorrhage was intracerebral hemorrhage (65.6%), intracerebral and intraventricular hemorrhage (30.3%), intraventricular hemorrhage (4.4%).

    Carotid angioplasty and stenting (CAS) has emerged as an alternative treatment of carotid stenosis for patients poorly suited for endarterectomy. Intracerebral hemorrhage following carotid revascularization is rare and thought to be related to hyperperfusion injury in most cases. Early experience suggests an increased incidence of hemorrhage following CAS as compared to endarterectomy. We describe a patient who suffered a thalamic hemorrhage following CAS. Because this hemorrhage occurred in a vascular territory unlikely to have been supplied by the treated artery, this case suggests that the mechanism of intracerebral hemorrhage following CAS may in some cases be different from the hyperperfusion hemorrhage classically described following endarterectomy.

    We investigated the effects of acrobatic training (AT) on expression of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) subunits in the sensorimotor cortex and striatum after intracerebral hemorrhage (ICH). Male Wistar rats were divided into 4 groups: ICH without AT (ICH), ICH with AT (ICH + AT), sham operation without AT (SHAM), and sham operation with AT (SHAM + AT). ICH was induced by collagenase injection into the left striatum. The ICH + AT group performed 5 acrobatic tasks daily on days 4-28 post ICH. Forelimb sensorimotor function was evaluated using the forelimb placing test. On days 14 and 29, mRNA expression levels of AMPAR subunits GluR1-4 were measured by real-time reverse transcription-polymerase chain reaction. Forelimb placing test scores were significantly higher in the ICH + AT group than in the ICH group. Expression levels of all AMPAR subunit mRNAs were significantly higher in the ipsilateral sensorimotor cortex of rats in the ICH + AT group than in that of rats in the ICH group on day 29. GluR3 and GluR4 expression levels were reduced in the ipsilateral striatum of rats in the ICH group compared with that of rats in the SHAM group on day 14. These changes may play a critical role in motor skills training-induced recovery after ICH. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Postoperative intra-abdominal massive bleeding is a rare and life-threatening complication associated with pancreaticoduodenectomy. Completion pancreatectomy (CP) was usually performed during reexploration for the complication. The management could decrease the complications, such as the pancreatic leakage or intraluminal infection after reexploration, but could increase mortality during the perioperative period. It also could result in loss of pancreatic function forever. This study evaluated an alternative surgical management for intra-abdominal massive hemorrhage to prevent pancreas function, simplify the surgical processes, and decrease the mortality of relaparotomy. Outcome after pancreaticojejunal bridge-anastomosis (PJBA) performed between January 2006 and June 2009 was compared with that after CP performed between February 1984 and December 2005. Between February 1984 and June 2009, 963 patients underwent the Whipple procedure (PD) or pylorus-preserving pancreaticoduodectomy (PPPD). Pancreatic leakage occurred in 103 patients (10.7%); 22 cases (21.4%) developed into intra-abdominal massive bleeding. Nonsurgical procedures of transarterial embolization (TAE) were performed in ten (45.45%) patients, of whom one died (10%). Twelve (54.55%) underwent reoperation. Five had CP with one death (20%). Pancreatic remnant was preserved by pancreaticojejunal bridge-anastomosis (PJBA) in seven patients with no deaths. The reexploration time was 340 +/- 48.2 min vs. 247.9 +/- 40.8 min (P endocrine insufficiency ("brittle" diabetes) and diarrhea (exocrine insufficiency). There were no evidences of exocrine and endocrine insufficiency in patients with PJBA. Pancreaticojejunal bridge-anastomosis is an easy, simple, and safe procedure for intra-abdominal massive hemorrhage associated with pancreaticoduodenectomy. It could decrease the mortality of reoperation and preserve the pancreatic function.

    Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

    To study the expression of T cell immunoglobulin and mucin domain 3 (Tim-3) on peripheral blood immunocytes, and the relationship between Tim-3 and the systemic inflammatory response or brain injury in patients with intracerebral hemorrhage (ICH). According to the volume of hematoma at 12 hours after onset of ICH, 60 newly diagnosed patients with ICH were divided into the small (volume of hematoma <30 mL, 30 cases) and large (volume of hematoma ≥30 mL, 30 cases) ICH groups. The expression of Tim-3 on peripheral blood immunocytes was analyzed by flow cytometry. Real-time reverse transcriptase polymerase chain reaction was used to detect Tim-3 mRNA on peripheral blood mononuclear cells (PBMCs). Meanwhile, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and S-100B protein were measured by enzyme-linked immunosorbent assay. Glasgow outcome scale (GOS) score at Day 30 was used to estimate prognosis of patients. The leukocyte count, neutrophil count, monocyte count, TNF-α, IL-1β, and S-100B protein increased remarkably after ICH. However, all of them in the large ICH group increased more obviously, and there were significant differences when compared with those in the small ICH group (P < .01). The expression of Tim-3 mRNA on PBMCs in the large ICH group increased remarkably, peaked at Day 3, and was positively associated with the concentrations of TNF-α, IL-1β, and S-100B protein (P < .01). Tim-3 was predominantly expressed itself on CD14 + monocytes. There was a negative correlation between GOS score and Tim-3 mRNA, TNF-α, IL-1β, or S-100B protein. The expression of Tim-3 on CD14 + monocytes involves in systemic inflammatory reaction after ICH and may be a novel treatment target. Copyright © 2018 National Stroke Association.

    Hepatic hemorrhage can be devastating, especially in patients with underlying hepatic pathology. This is a case report of a 50-year-old man who presented to the emergency room with Stage 3 shock as evidenced by a systolic blood pressure of 90 mmHg, a heart rate of 125 beats per minute, respiration of 32, with delayed capillary refill and agitation. At this time, he was found to have a massive spontaneous intra-abdominal hemorrhage with an advanced stage of amyloidosis with multiple organ malfunctions. The initial diagnosis was based on an abdominal computed tomography scan and the patient was taken expeditiously to a hybrid angiography suite for a celiac angiogram. An intraoperative diagnosis of extravasation from amyloid related vasculopathy was made based on the angiographic appearance of hepatic circulation. Coil embolization of the feeding branch of the bleeder was achieved using the interlock coil system and a completion angiogram was done showing complete cessation of active bleeding. The postoperative phase was uneventful and the patient was discharged home on postoperative day three. His postoperative visit at five months later was unremarkable. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available A 61-year-old woman was admitted to hospital because of generalized edema and proteinuria. Her renal function deteriorated rapidly. Serum immunoglobulin and complement levels were within normal ranges. An autoantibody examination showed negative for antinuclear antibody and antineutrophil cytoplasmic antibody. Histologic examination of a renal biopsy specimen revealed that all of the glomeruli had severe crescent formations with no immune deposits. The patient was treated with steroid pulse therapy with cyclophosphamide followed by oral prednisolone. Fifteen days later, she experienced massive recurrent hematochezia. Angiography revealed an active contrast extravasation in a branch of the distal ileal artery. We selectively embolized with a permanent embolic agent. On the 45th hospital day, the patient suddenly lost consciousness. Brain computed tomography showed intracerebral hemorrhage. We report a case of antineutrophil cytoplasmic antibody–negative pauci-immune glomerulonephritis with massive intestinal bleeding and cerebral hemorrhage.

    2016-09-01

    Bees and wasps of the Hymenoptera order are encountered on a daily basis throughout the world. Some encounters prove harmless, while others can have significant morbidity and mortality. Hymenoptera venom is thought to contain an enzyme that can cleave phospholipids and cause significant coagulation abnormalities. This toxin and others can lead to reactions ranging from local inflammation to anaphylaxis. We report a single case of a previously healthy man who presented to the emergency department with altered mental status and anaphylaxis after a massive honeybee envenomation that caused a fall from standing resulting in significant head injury. He was found to have significant coagulopathy and subdural bleeding that progressed to near brain herniation requiring emergent decompression. Trauma can easily occur to individuals escaping swarms of hymenoptera. Closer attention must be paid to potential bleeding sources in these patients and in patients with massive bee envenomation.

    A male infant born prematurely at 31 weeks of gestation weighed 789 g and had mildly brown-colored oral/tracheal aspirates at delivery. The amniotic fluid was also discolored, and its index was below 5. The patient died of hypoxemic respiratory and cardiac failure 2 hours after birth. The maternal profiles showed placenta previa and intrauterine growth restriction (IUGR) at 22 weeks of gestation, and revealed recurrent episodes of antenatal and substantial vaginal bleeding and oligohydramnios, indicating chronic abruption-oligohydramnios sequence. The thickened placenta, weighing 275 g, grossly displayed unevenness and diffuse opacity with green to brown discoloration in the chorioamniotic surface, and revealed chronic massive subchorial hematomas (Breus' mole) with old peripheral blood clot, circumvallation, and infarction. Microscopically, diffuse Berlin-blue staining-positive hemosiderin deposits were readily encountered in the chorioamniotic layers of the chorionic plate, consistent with diffuse chorioamniotic hemosiderosis (DCH) due to Breus' mole, accompanied by diffuse amniotic necrosis. At autopsy, an external examination showed several surface anomalies and marked pulmonary hypoplasia, 0.006 (less 0.012) of lung:body weight ratio. Since Breus' mole has a close relationship with intrauterine hemorrhage, resulting in DCH, IUGR, and/or pulmonary hypoplasia of the newborn, the present features might be typical. © 2012 The Authors.

    Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

    CT scan is recognized to be a rapid, noninvasive and informative examination in evaluation of the head injured patient. It is also possible to evaluate the presence of the intracerebral hematoma without remarkable mass effect, cerebral contusion, associated cerebral edema and ventricular hemorrhage. We present a case of traumatic intraventricular hemorrhage. The patient was a 40-year-old male admitted to our hospital in a drowsy state following a fall from about one meter high. Craniogram showed a linear fracture in the left parietotemporal regions. In the CT scan, intraventricular hemorrhage associated with subarachnoid hemorrhage without intracerebral hematoma was shown. A symmetrical moderate dilatation of both lateral ventricles was also shown. Cerebral angiography revealed no abnormality. His condition deteriorated progressively, so ventricular drainage was performed, but he expired 5 days later. Considering this case, the mechanisms of pure intraventricular hemorrhage following head injury were discussed. (author)

    Prior to the introduction of the CT scan, the diagnosis of intraventricular hemorrhage (IVH) was very difficult. The CT scan has, though, been recognized to be extremely informative in the evaluation of IVH. During the first three years we have had experience with 91 cases of IVH diagnosed by the CT scan. Acute death within seven days occurred in 42 of these cases. Hypertension was the most common Acute death within seven days occurred in 42 of these cases. Hypertension was the most common etiological factor, accounting for 18 cases. Cerebral aneurysm was the second most common cause, accounting for 10 cases. Head injury was seen in 8 cases, while the causes of 4 deaths were unknown. 31 cases were distributed over all ventricles. 30 cases revealed over two cast formations. The presence of IVH in the third and/or the fourth ventricle, which can easily affect the function of the hypothalamus and the brain stem anatomically, was closely correlated with the high mortality rate. The analysis of the CT findings regarding the mechanisms of IVH reveals three types: the direct type, which bleeds directly into ventricles without forming definite intracerebral hematomas; the extension type, which is characterized by extension and rupture from massive intracerebral hematoma, and the reflux type, which is characterized by a reflux of the subarachnoid blood. The prognosis depends on the differences in these mechanisms. (author)

  17. Outcomes after endoscopic port surgery for spontaneous intracerebral hematomas.

    Spontaneous intracerebral hemorrhages (ICHs) cause significant morbidity and mortality. Traditional open surgical management strategies offer limited benefit except for the most superficial hemorrhages in select patients. Recent reports suggest that endoscopic approaches may improve outcomes, particularly for deep subcortical hemorrhages. However, the management of these patients remains controversial. We reviewed our experience using endoscopic port surgery to identify characteristics that may predict acceptable outcomes. We completed a retrospective chart and imaging review of patients who underwent endoscopic port surgery for evacuation of spontaneous ICH at a single center. Data were gathered regarding patient demographics, hemorrhage locations, operative findings, and clinical outcomes. From 2007 to 2011, 18 patients underwent evacuation of spontaneous intracerebral hematomas using an endoscopic port. The mean age in years was 62 years (range, 43-84 years). Six of 18 patients (33%) died before discharge, and 2 others (11%) died after at least 1 month of survival. Of 12 initial survivors, all were discharged to a rehabilitation or nursing facility. Complete hematoma evacuation was achieved in 7 of 18 patients, with the remaining 11 having a partial evacuation. The patients who died (n = 6) before discharge were statistically more likely to have a left-sided hemorrhage, partial evacuation, or older age than the survivors; death at least 1  month after evacuation was additionally associated with greater preoperative hematoma volumes. Our series demonstrates that endoscopic port surgery for acute intracerebral hematoma evacuation has the ability to achieve significant decompression of large and deep-seated hematomas. Patient age, extent of evacuation, laterality, and preoperative hematoma volume appear to influence patient outcome. Most overall outcomes remain poor. Future studies are necessary to determine if surgical evacuation is in fact superior to best

    Durining the last 2 years, 46 cases of hypertensive intracerebral hemorrhage in the basal ganglia were treated by CT guided stereotactic aspiration and their outcome was evaluated in terms of the rate of hematoma removal, the change of consciousness level and the recovery of motor and sensory functions. They are aged from 45 to 79 years old, the average 56, and aspirated 1 to 24 days after the onset, two third of them being within 1 week. The whole procedure was done in the CT room under direct CT guidance and by one trial. In putaminal type hemorrhage, the removed hematoma volumes ranged from 9 to 48 ml, average being 23.7 ml, in thalamic type from 5 to 29 ml, average being 15.5 ml. The average rate of removal was 81.1 % in 30 cases within 1 week. In most cases, preoperative consciousness was not severely disturbed, in putaminal type, 19 were alert or confused, 4 somnolent, 5 stuperous and in thalamic type, 6, 6, 3 respectively and 2 were semicomatous, one of them had herniation sign. In putaminal type all but 2 cases recovered to alert or confused state, the first one had postoperative bleeding and the other was already apallic preoperatively. In thalamic type, we lost 3 cases, 2 by gastrointestinal bleeding and 1 DIC, by rehemorrhage 2 months after the operation. All but one who was semicomatous preoperatively recovered to alertness. In motor function, some cases of the putaminal bleeding with intact internal capsule remained hemiplegic. On the other hand, most of the cases with partial destruction of the internal capsule on CT recovered well in both types of hematoma. Especially in thalamic type, only 2 had inability to walk durinig the follow-up period. In sensory function, two thirds of the cases recovered to almost normal level. CT guided stereotactic aspiration, therefore, can be evaluated as less invasive and more definitive treatment for intracerebral hematoma in the basal ganglia. (author)

    Recent advancement of CT system provides not only definite diagnosis and location of intracerebral hematoma but also coordinates of the center of the hematoma. Trials of stereotactic evacuation of the hematoma have been reported by some authors in the cases of subacute or chronic stages of hypertensive intracerebral hemorrhage. In this series, similar surgery has been performed in 33 cases of hypertensive intracerebral hematoma including 22 cases in acute stage, and 2 cases of traumatic hematoma. Clinical outcomes were investigated and the results were considered to be equivalent or rather better in the conventional microsurgery with evacuation of hematoma under direct vision. However, there still remained controversial problems in the cases of threatened herniation signs, because in these cases regular surgery with total evacuation of the hematoma at one time might have been preferable. The benefits of this CT guided stereotactic approach for the evacuation of the hematoma were thought to be as follow: 1) the procedure is simple and safe, 2) operation is readily performed under local anesthesia, and 3) the hematoma was drained out totally by means of urokinase activity. It is our impression that this surgery not only is indicated as emergency treatment for the patients of high-age or in high risk, but also can institute as a routine surgery for the intracerebral hematomas in patients showing no herniation sign.

    Intraventricular hemorrhage (IVH) is a cause of significant morbidity and mortality and is an independent predictor of a worse outcome in intracerebral hemorrhage (ICH) and germinal matrix hemorrhage (GMH). IVH may result in both injuries to the brain as well as hydrocephalus. This paper reviews evidence on the mechanisms and potential treatments for IVH-induced hydrocephalus. One frequently cited theory to explain hydrocephalus after IVH involves obliteration of the arachnoid villi by microt...

  1. Imaging of Hemorrhagic Stroke.

    Science.gov (United States)

    2016-10-01

    Hemorrhagic stroke comprises approximately 15% to 20% of all strokes. This article provides readers with an understanding of the indications and significance of various neuroimaging techniques available for patients presenting with hemorrhagic strokes of distinct causes. The most common initial neuroimaging study is a noncontrast head CT, which allows for the identification of hemorrhage. Once an intracranial hemorrhage has been identified, the pattern of blood and the patient's medical history, neurologic examination, and laboratory studies lead the practitioner to pursue further neuroimaging studies to guide the medical, surgical, and interventional management. Given that hemorrhagic stroke constitutes a heterogeneous collection of diagnoses, the subsequent neuroimaging pathway necessary to better evaluate and care for these patients is variable based on the etiology.With an increasing incidence and prevalence of atrial fibrillation associated with the aging population and the introduction of three new direct factor Xa inhibitors and one direct thrombin inhibitor to complement vitamin K antagonists, oral anticoagulant use continues to increase. Patients on oral anticoagulants have a sevenfold to tenfold increased risk for intracerebral hemorrhage (ICH). Furthermore, patients who have an ICH associated with oral anticoagulant use have a higher mortality rate than those with primary ICH. Despite the reduced incidence of hypertension-related ICH over the past decade, it is expected that the incidence of ICH will continue to increase. Neuroimaging studies are integral to the identification of hemorrhagic stroke, determination of the underlying etiology, prevention of hematoma expansion, treatment of acute complications, and treatment of the underlying etiology, if indicated. Neuroimaging is essential for prognostication and thus directly impacts patient care.

    Eleven cases of neonatal intracranial hemorrhage were diagnosed and followed up by CT scanning. By CT, hemorrhagic lesions were shown as high density areas in an acute stage and imaged as low density areas after the hemorrhage was absorbed. The time of absorption varies depending upon the site and the severity of hemorrhage. Intraventricular hemorrhage, petechial hemorrhage and subdural hematoma were absorbed rapidly in more than 70% of the exanimed cases, CT scanning 1 - 2 weeks after the onset revealed absorption of hemorrhage. However, the absorption delayed in intracerebral hematoma; CT scan taken after one month showed hemorrhagic lesions remaining in 75% of the cases. In nine cases who survived, following the absorption of the hemorrhagic lesions, cerebral atrophy was observed in 4 cases (44%), ventricular enlargement in 3 cases (33%), and complete recovery in 2 cases (22%). From these results, CT scanning for diagnosis of neonatal intracranial hemorrhage should be done before the hemorrhagic lesion is absorbed (within 7 days of the onset). Follow-up study by CT is important for observing changes and predicting prognosis of intracranial hemorrhage. (Ueda, J.)

    Prior to the introduction of computed tomography, the clinical and radiological diagnosis of the intraventricular hemorrhage in living patients was difficult. C.T. scanning is an invaluable investigation providing the rapid and noninvasive diagnosis of intracerebral and intraventricular hemorrhage. It reliably demonstrates the presence and distribution of fresh blood within the ventricular system. C.T. is also useful as a surgical guidance and in the evaluation of fate of the hematoma by easily performable follow-up studies. We reviewed 31 cases of intraventricular hemorrhage in C.T. in the department of radiology of Ewha Womans University Hospital during the period from August, 1982 to August, 1983. The results were as follows: 1. The most patients were encountered in the 5th decade and the male to female ratio was 1.2 : 1. 2. Hypertension was the main cause of the intraventricular hemorrhage; 18 out of 31 patients. Remaining 13 patients were caused by hypoxia, aneurysm, Moya Moya disease, coagulation defect, trauma and undetermined etiology. 3. 18 out of 31 patients showed hemorrhage in the lateral ventricles only and all ventricles in 10 patients. 4. 28 out of 31 patients showed associated with intracranial hematoma; Those were intracerebral hematomas in 16 patients, intracerebral hematoma with subarachnoid hemorrhage in 4 patients and extracerebral hematoma in 2 patients. 5. Outcome was assessed using the Glasgow scale. According to them, the total mortality rates was 54.8%, however, 32.3% of patients returned to normal or minor disability. Patients, who had hypertension and marked degree of hemorrhage in the ventricular systems had a poor outcome. Patients with only ventricular hemorrhage had better outcome than associated intracranial hematoma. 6. 16 out of 31 patients were treated by surgical methods and 15 out of 31 patients by conservative methods. 75% of patients were died in conservative treatment. 7.

    Hemorrhagic stroke is more common in non-Western settings and does not always share risk factors with other cardiovascular diseases. The association of smoking with hemorrhagic stroke subtypes has not been established. We examined the association of cigarette smoking with hemorrhagic stroke, by subtype (intracerebral hemorrhage and subarachnoid hemorrhage), in a large cohort of older Chinese from Hong Kong. Multivariable Cox regression analysis was used to assess the adjusted associations of smoking at baseline with death from hemorrhagic stroke and its subtypes, using a population-based prospective cohort of 66 820 Chinese aged>65 years enrolled from July 1998 to December 2001 at all the 18 Elderly Health Centers of the Hong Kong Government Department of Health and followed until May 31, 2012. After follow-up for an average of 10.9 years (SD=3.1), 648 deaths from hemorrhagic stroke had occurred, of which 530 (82%) were intracerebral hemorrhage. Current smoking was associated with a higher risk of hemorrhagic stroke (hazard ratio, 2.19; 95% confidence interval, 1.49-3.22), intracerebral hemorrhage (1.94; 1.25-3.01), and subarachnoid hemorrhage (3.58; 1.62-7.94), adjusted for age, sex, education, public assistance, housing type, monthly expenditure, alcohol use, and exercise. Further adjustment for hypertension and body mass index slightly changed the estimates. Smoking is strongly associated with hemorrhagic stroke mortality, particularly for subarachnoid hemorrhage.

    1. We have reviewed 34 cases of neonatal intracranial hemorrhages (perinatal onset, 23 mature and 11 premature infants) experienced in 10-year period from 1971 to 1980, with special reference to gestational age, birth weight, type of delivery, presence or absence of asphyxia, symptoms and cause of death. 2. Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages. (author)

    CT scans were analysed retrospectively in 130 patients with subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysm to evaluate the relationship of the locations of aneurysms and the patterns of hemorrhage. Hemorrhage corresponded to the site of aneurysmal origin in a general way and in more specific ways to anterior communicating and middle cerebral artery aneurysms when there was parenchymal or cisternal hemorrhage. In anterior communicating artery aneurysm, SAH in the interhemispheric fissure, both sylvian fissures, and basal cistern was usually noted and intracerebral hemorrhage in anteroinferior frontal lobe was sometimes associated. In cases of middle cerebral artery aneurysm, hemorrhage in the ipsilateral sylvian fissure, interhemispheric fissure, and ipsilateral basal cistern was usual. Intracerebral hemorrhage in lateral temporal lobe was sometimes associated. Posterior communicating artery aneurysm demonstrated SAH in the ipsilateral basal cistern or in entire cisternal spaces specifically, so with higher incidence of involvement of the quadrigeminal and superior cerebellar cistern than anterior cerebral or middle cerebral artery aneurysm. We suggest the locations of aneurysm might be predicted with patterns of SAH and / or associated intracerebral hemorrhage with CT

    High mortality and severe grade of disability observed in patients after intracerebral hemorrhage provide efforts to improve diagnostics and therapy of the hemorrhagic cerebral stroke. An aim of this paper was an evaluation of blood resorption dynamics in patients with intracerebral hematoma, performed with computed tomography of the head and an analysis of clinical significance of this process. An examined group included 133 patients with intracerebral hematoma proven by a CT exam. In 97 patients resorption of the hematoma was measured, based on control scans taken on 15 th and 30 th day on average. Volume of the hemorrhagic foci was measured as well as the width of ventricles and the displacement of medial structures. The mean hematoma volume reached 11,59 ml after 15 days, and 3,16 m after 30 days (average decrease of the volume 0,67 ml/day). There was a significant difference in the rate of resorption between the first (0-15 days) and the second (15-30 days) observation period - 0,78 and 0,62 ml/day respectively. The dynamics of the process was dependent on volume and localization of the hematoma and independent of the grade of displacement and compression of the ventricles. The calculated mean rate of the hematomas resorption enables to schedule control examinations precisely. The significant differences of the dynamics of blood resorption depending on hematomas size and the independence of compression and displacement of ventricular system suggest, that the most important factor in therapeutic decision-making should be a clinical status of the patient.

    Computed tomography has been established as an indispensable tool in the detection of intracranial hemorrhages. Extra axial fluid collections are usually easily distinguished from intracerebral hemorrhages. However, hemorrhages in atypical locations, such as in falx and tentorial regions, can be difficult to diagnose with CT. The tentorial and falcial collection of subdural blood are rather unusual. Authors report here 84 cases of falcial and tentorial subdural hemorrhages with reference data that we have encountered in the last two years. The results were as follows; 1. In 589 cases of intracranial hemorrhage, the incidence of subdural hemorrhage was 372 cases (63.2%). 2. Among 372 cases with subdural hemorrhage, 84 cases (22.6%) had falcial and/or tentorial subdural hemorrhage. In 84 cases with falcial and/or tentorial subdural hemorrhage, there were 50 cases (13.4%) of falcial subdural hemorrhages, 21 cases (5.7%) of tentorial subdural hemorrhage and 13 cases (3.5%) of combined falcial and tentorial subdural hemorrhage. 3. The location of falcial subdural hemorrhage was anterior in 30 cases (60%), posterior in 15 cases (30%) and middle in 5 cases (10%). 4. The location of tentorial subdural hemorrhage was petrous edge in 7 cases (33.3%), occipital attachment in 6 cases (28.6%), tentorial hiatus in 5 cases (23.8%), and diffuse in 3 cases (14.3%). 5. In 13 cases showing combined falcial and tentorial subdural hemorrhage, there was 3 cases (23.1%) of posterior falx and tentorial hiatus, 2 cases (15.4%) of anterior falx and petrous edge, 2 cases of anterior falx and tentorial hiatus, 2 cases of posterior falx and petrous edge, 2 cases of posterior falx and occipital attachment, 1 case (7.7%) of posterior falx and diffuse, and 1 case of posterior, middle falx and diffuse. 6. In the cases with falcial and/or tentorial subdural hemorrhage, the incidence of associated intracranial hemorrhage were intracrania subdural hemorrhage in 40 cases (47.6%), hemorrhagic brain

    Between 1980 and 1994, 423 patients with esophageal cancer were given curative r[iation therapy. Of these patients, 31 died of massive hemorrhage and were used as the subjects of analysis in this study. The incidence of massive hemorrhage in all patients was 7% (31/423). In the 31 patients who died of massive hemorrhage, 27 h[ local tumors and two h[ no tumors at hemorrhage (two unknown cases). The mean time interval from the start of r[iation to hemorrhage was 9.2 months. In 9 autopsy cases the origin of hemorrhage was a tear of the aorta in 5 cases, necrotic local tumor in 3 cases and esophageal ulcer in 1 case. The positive risk factors for this complication seemed to be excess total dose, infection, metallic stent, and tracheoesophageal fistula. Chest pain or sentinel hemorrhage proceeding to massive hemorrhage was observed in about half of the patients. (orig.)

    Intracerebral hemorrhage (ICH) volume, particularly if ≥30 mL, is a major determinant of poor outcome. We used a multinational ICH data registry to study the characteristics, course, and outcomes of supratentorial hematomas with volumes hematoma expansion, Glasgow Outcome Scale (GOS), and in-hospital death. Poor outcome was defined as composite of in-hospital death and severe disability (GOS ≤ 3). Comparison was conducted based on hemorrhage location. Logistic regression using dichotomized outcome scales was applied to determine predictors of poor outcome. Among 375 cases of supratentorial ICH with volumes hematomas <30 mL expands, leading to END or death. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Tissue plasminogen activator (tPA) is the only approved therapy for acute ischemic stroke. However, delayed tPA treatment increases the risk of cerebral hemorrhage and can result in exacerbation of nerve injury. ADAMTS13, a von Willebrand factor (VWF) cleaving protease, has a protective effect against ischemic brain injury and may reduce bleeding risk by cleaving VWF. We examined whether ADAMTS13 has a longer therapeutic time window in ischemic stroke than tPA in mice subjected to middle cerebral artery occlusion (MCAO). ADAMTS13 (0.1mg/kg) or tPA (10mg/kg) was administered i.v., immediately after reperfusion of after 2-h or 4-h MCAO for comparison of the therapeutic time windows in ischemic stroke. Infarct volume, hemorrhagic volume, plasma high-mobility group box1 (HMGB1) levels and cerebral blood flow were measured 24h after MCAO. Both ADAMTS13 and tPA improved the infarct volume without hemorrhagic complications in 2-h MCAO mice. On the other hand, ADAMTS13 reduced the infarct volume and plasma HMGB1 levels, and improved cerebral blood flow without hemorrhagic complications in 4-h MCAO mice, but tPA was not effective and these animals showed massive intracerebral hemorrhage. These results indicated that ADAMTS13 has a longer therapeutic time window in ischemic stroke than tPA, and ADAMTS13 may be useful as a new therapeutic agent for ischemic stroke.

    Full Text Available Inconsistency of the current classification of cerebral intraventricular hemorrhages is discussed in the article. The author explains divergence of including of the subependymal (1st stage and intracerebral (4th stage hemorrhages into this classification. A new classification of cerebral intraventricular hemorrhages including their origin, phases and stages is offered. The most common origin of intraventricular hemorrhages is subependymal hemorrhage (82,2%. Two phases of hemorrhage were distinguished: bleeding phase and resorption phase. Stages of intraventricular hemorrhages reflecting the blood movement after the onset of bleeding are the following: 1 — infill of the up to ½ of the lateral ventricles without their enlargement; 2 — infill of more than ½ of the lateral ventricles with their enlargement; 3 — infill of the IV ventricle, of the cerebellomedullary cistern and its dislocation into the subarachnoid space of the cerebellum, pons varolii, medulla oblongata and spinal cord.

    Full Text Available Hemoglobin-vesicles (HbV, encapsulating highly concentrated human hemoglobin in liposomes, were developed as a substitute for red blood cells (RBC and their safety and efficacy in transfusion therapy has been confirmed in previous studies. Although HbV suspensions are structurally and physicochemically stabile for least 1-year at room temperature, based on in vitro experiments, the issue of whether the use of long-term stored HbV after a massive hemorrhage can be effective in resuscitations without adverse, post-transfusion effects remains to be clarified. We report herein on a comparison of the systemic response and the induction of organ injuries in hemorrhagic shock model rats resuscitated using 1-year-stored HbV, freshly packed RBC (PRBC-0 and by 28-day-stored packed RBC (PRBC-28. The six-hour mortality after resuscitation was not significantly different among the groups. Arterial blood pressure and blood gas parameters revealed that, using HbV, recovery from the shock state was comparable to that when PRBC-0 was used. Although no significant change was observed in serum parameters reflecting liver and kidney injuries at 6 hours after resuscitation among the three resuscitation groups, results based on Evans Blue and protein leakage in bronchoalveolar lavage fluid, the lung wet/dry weight ratio and histopathological findings indicated that HbV as well as PRBC-0 was less predisposed to result in a post-transfusion lung injury than PRBC-28, as evidenced by low levels of myeloperoxidase accumulation and subsequent oxidative damage in the lung. The findings reported herein indicate that 1-year-stored HbV can effectively function as a resuscitative fluid without the induction of post-transfused lung injury and that it is comparable to fresh PRBC, suggesting that HbV is a promising RBC substitute with a long shelf-life.

    Full Text Available Spontaneous hypertensive brainstem hemorrhage is the spontaneous brainstem hemorrhage associated with long term hypertension but not having definite focal or objective lesion. It is a catastrophic event which has a poor prognosis and usually managed conservatively. It is not uncommon, especially in eastern Asian populations, accounting approximately for 10% of the intracerebral hemorrhage. Before the advent of computed tomography, the diagnosis of brainstem hemorrhage was usually based on the clinical picture or by autopsy and believed to be untreatable via surgery. The introduction of computed tomography permitted to categorize the subtypes of brainstem hemorrhage with more predicted outcome. Continuous ongoing developments in the stereotactic surgery and microsurgery have added more specific surgical management in these patients. However, whether to manage conservatively or promptly with surgical evacuation of hematoma is still a controversy. Studies have shown that an accurate prognostic assessment based on clinical and radiological features on admission is critical for establishing a reasonable therapeutic approach. Some authors have advocate conservative management, whereas others have suggested the efficacy of surgical treatment in brainstem hemorrhage. With the widening knowledge in microsurgical techniques as well as neuroimaging technology, there seems to have more optimistic hope of surgical management of spontaneous hypertensive brainstem hemorrhage for better prognosis. Here we present five cases of severe spontaneous hypertensive brainstem hemorrhage patients who had undergone surgery; and explore the possibilities of surgical management in patients with the spontaneous hypertensive brainstem hemorrhage.

    Full Text Available Spontaneous intracerebral hemorrhage (SICH, defined broadly as intracerebral hemorrhage not related to trauma, results in long-term disability or death in a large proportion of afflicted patients. Current management of this disease is predominantly supportive, including airway protection, optimization of hemodynamic parameters, and management of intracranial pressure. No active treatments that demonstrate beneficial effects on clinical outcome are currently available. Animal models of SICH have allowed for the elucidation of multiple pathways that may be attractive therapeutic targets. A minority of these, such as aggressive blood pressure management and recombinant activated factor VII administration, have lead to large-scale clinical trials. There remains a critical need for further translational research in the realm of SICH.

  18. Endoscopic hematoma evacuation in patients with spontaneous supratentorial intracerebral hemorrhage

    Conclusion: With the introduction of the minimally invasive techniques and the evolution of the neuroendoscope and hemostatic agents, the median operative time and blood loss have been significantly decreased. Although the hematoma evacuation rates were similar between the endoscope (90% and craniotomy (85% groups, the median intensive care unit stay was decreased from 11 days to 6 days due to reduced surgical invasiveness. This represents an important advancement in treating spontaneous supratentorial ICH, and provides a measured preview of the promising results that can be expected in the future.

    Larvae of Hypoderma bovis accidentally parisitize man. These larvae can penetrate into the brain by a path which remains unknown, causing an intracerebral haematoma and clinical signs. Computerized tomography shows the haematoma, and carotid angiography shows the absence of a vascular malformation, but these examinations do not allow etiological diagnosis. This is suggested by seroimmunological examinations and by the discovery of the larva during the operation. We report findings in a 6 1/4 year old boy.

    To clarify the evolution of traumatic intracerebral hematoma (TICH), initial computerized tomography (CT) scans of 28 TICH cases performed within one hour after head trauma were studied along with their follow-up CT scans. They were classified into the following two groups; per-acute group included seven cases in which TICH was completed on the initial CT scans taken within one hour after head injury and acute group included 21 cases in which the initial CT scans revealed isodensity or high density spot and repeat CT scans disclosed TICH by 48 hours after injury. In the per-acute group, initial CT scans showed a homogeneous, well defined, and high density mass (1.5-6.5 cm in diameter). In sequential CT scans of the three cases, the hematoma did not increase but spontaneously disappeared. Other four cases died early after head trauma. Their initial CT scans revealed a large high density mass (3-6.5 cm in diameter) combined with other extracerebral hemorrhages. In the acute group, initial CT scans demonstrated isodensity or high density spot and sequential CT scans showed mottled appearance of salt and pepper appearance, and after a while showed fusion of small high density areas to become a massive high density area (contusional hematoma) by 48 hours after injury. In six cases of this group, the contusional hematoma was removed within 24 hours after injury and in one case at 3.5 days. In other 14 cases, the hematomas shrank or disappeared spontaneously. From these results, it was considered that evolution of TICH's were classified into the two groups; per-acute group resulting from rupture of vessels and acute group resulting from contusion.

    Clinical pigns, laboratory data, CT findings, CSF spectrophotometric findings and CSF/blood glucose ratio were reviewed on thirty six newborns with intracranial hemorrhage confirmed by CT and/or autopsy and the following findings were obtained. The sites of hemorrhage were: intraventricular 14, intracerebral 4, subdural 2, subarachnoidal 16. 1) Convulsion (39%), hypotonia (58%), apnea (47%), and bradycardia (58%) were seen, but those were not regarded as specific for the intracranial hemorrhage. 2) Severe anemia of hemoglobin value less than 14 g/dl (17%), more than 10% fall of hematocrit (10%), and hyperglycemia of blood glucose more than 200 mg/gl (42%) were seen almost equally in every type of hemorrhage. 3) On CSF spectrophotometry, ajj twelve cases of intraventricular and four cases of intracerebral hemorrhage had the oxyhemoglobin peak absorbance. However, of fourteen cases of subarachnoidal hemorrhage, three had the oxyhemoglobin peak absorbance but the other eleven cases had the bilirubin peak absorbance. 4) Hypoglycorrachia, defined as CSF/blood glucose ratio less than 0.4, was recognized only in the intraventricular hemorrhage group (5/9, 56%). It was concluded that lumbar puncture should be done first of all when intracranial hemorrhage is suspected. If hypoglycorrachia or oxyhemoglobin peak absorbance is recognized, computed tomography should be performed immediately to know the accurate site and extent of hemorrhage. Although hypoglycorrachia is more specific for the intraventricular hemorrhage, it is usually found several days after the hemorrhage. On the other hand, oxyhemoglobin can be identified in CSF within a day after the episode of hemorrhage and this method is more benifical for the early diagnosis. (author)

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

    Full Text Available Intracerebral hemorrhage (ICH, a form of brain bleeding and minor subtype of stroke, leads to significant mortality and long-term disability. There are currently no validated approaches to promote functional recovery after ICH. Research in stroke recovery and rehabilitation has largely focused on ischemic stroke, but given the stark differences in the pathophysiology between ischemic and hemorrhagic stroke, it is possible that strategies to rehabilitate the brain in distinct stroke subtypes will be different. Here, we review our current understanding of recovery after primary intracerebral hemorrhage with the intent to provide a framework to promote novel, stroke-subtype specific approaches.

    Computed tomography (CT) is a new non-invasive diagnostic imaging method, which has ability to differentiate C.S.F., hematoma, and even edematous brain from normal brain tissue. Prior to the introduction of the CT, the diagnosis of the intraventricular hemorrhage in living patients was difficult and was confirmed by surgery of autopsy. Intracranial hemorrhages are visible on the CT with density higher than brain tissue in acute phase. CT is an accurate method for detecting of intraventricular hemorrhage including detection of nature, location, amount, and associated changes. CT is also useful as a guidance and in the evaluation of fate of the hematomas by easily performable follow up studies. The causes of the intraventricular hemorrhages are hypertension, rupture of aneurysm, arteriovenous malformation, head trauma, brain tumor, and others. This study included evaluation of CT of 69 patients who show the high density in cerebral ventricular system during the period of 31 months from Feb. 1979 to Aug. 1981 in the Department of Radiology, College of Medicine, Hanyang University. The results were as follows. 1. Age distribution of the total 69 patient was broad ranging from 1 month to 80 years. 28% of patients were in the 6th decade. The mate to female ratio was 2 : 1. 2. The consciousness of patients at CT study: Those were conscious in 11 cases, stuporous in 41 cases and unconscious in 17 cases. 3. The causes of intraventricular hemorrhages were hypertension in 28 cases, head trauma in 12 cases, aneurysm in 4 cases, tumor in 2 cases and others in 23 cases. 4. 9 cases showed intraventricular hematomas only, other 60 cases showed associated intracranial hematomas: Those were intracerebral hematomas in 53 cases including 30 cases of basal ganglial and thalamic hematomas, subarachnoid hemorrhage in 17 cases, epidural hematomas in 3 cases, and subdural hematomas in 2 cases. 5. All cases of the intraventricular hematomas except one sowed hematoma in the lateral

    Intracerebral hemorrhage is a rare event during pregnancy that can result in serious morbidity and mortality for the mother and infant. In this article, we describe a case involving a multiparous woman at 34 weeks gestation who presented with a 5-cm intracerebral bleed. Within 2 hours of presenting, she underwent an emergency cesarean and craniotomy to remove the hematoma. The woman's altered mental status fully abated, and she was discharged with minimal neurologic deficits. The newborn was born healthy.

    We report a case of a 17-year-old male who had hit the front of his head in a traffic accident. CT scan revealed contusional hemorrhage and pneumocephalus of the left frontal lobe 10 hours after the accident. A month later he complained of rhinorrhea and CT scan revealed intracerebral pneumocephalus. One day he complained of headache and began to vomit after he sneezed. CT scan revealed that the pneumocephalus had become worse and air had spread throughout the subarachnoid space. Bone CT scan revealed the air communicated from the frontal sinus to the intracerebral air cavity. 3D-CT scan revealed bone defect in the roof of the ethmoid sinus. The intraoperative findings revealed that the intracerebral air cavity communicated with the frontal sinus and ethmoid sinus. Though the brain which dropped into the paranasal sinus, adhered to the dura mater around the bone defect, a part of the brain had come off from the dura mater around the frontal sinus. We suspected that the intracerebral air cavity communicated with the frontal sinus initially. When the air cavity communicated with the ethmoid sinus secondarily, intracranial pressure abated and air came into the subarachnoid space from the frontal sinus.

    Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

    Six patients with acute hemorrhagic brain infarct were imaged using spin-echo (SE) pulse sequences on a 1.5 Tesla MR scanner. Including two patients with repeated MR imaging, a total of eight examinations, all performed within 15 days after stroke, were analyzed retrospectively. Four patients revealed massive hemorrhages in the basal ganglia or cerebellum and three cases demonstrated multiple linear hemorrhages in the cerebral cortex. On T1-weighted images, hemorrhages were either mildly or definitely hyperintense relative to gray matter, while varied from mildly hypointense to hyperintense on T2-weighted images. T1-weighted images were superior to T2-weighted images in detection of hemorrhgage. CT failed to detect hemorrhage in two of five cases: indicative of MR superiority to CT in the diagnosis of acute hemorrhagic infarcts. (author)

  15. Intracranial Hemorrhage

    Science.gov (United States)

    2011-01-01

    Intracranial hemorrhage is a life-threatening condition, the outcome of which can be improved by intensive care. Intracranial hemorrhage may be spontaneous, precipitated by an underlying vascular malformation, induced by trauma, or related to therapeutic anticoagulation. The goals of critical care are to assess the proximate cause, minimize the risks of hemorrhage expansion through blood pressure control and correction of coagulopathy, and obliterate vascular lesions with a high risk of acute rebleeding. Simple bedside scales and interpretation of computed tomography scans assess the severity of neurological injury. Myocardial stunning and pulmonary edema related to neurological injury should be anticipated, and can usually be managed. Fever (often not from infection) is common and can be effectively treated, although therapeutic cooling has not been shown to improve outcomes after intracranial hemorrhage. Most functional and cognitive recovery takes place weeks to months after discharge; expected levels of functional independence (no disability, disability but independence with a device, dependence) may guide conversations with patient representatives. Goals of care impact mortality, with do-not-resuscitate status increasing the predicted mortality for any level of severity of intraparenchymal hemorrhage. Future directions include refining the use of bedside neuromonitoring (electroencephalogram, invasive monitors), novel approaches to reduce intracranial hemorrhage expansion, minimizing vasospasm, and refining the assessment of quality of life to guide rehabilitation and therapy.

    We report 2 cases of intracerebral cysticercosis. One was followed up by CT with preservative treatment, and the other, treated surgically. Case 1: A 60-year-old man who had lived in Korea until the age of 12 and who had often eaten raw pork. He had been diagnosed as having cysticercosis after the excision of facial and somatic nodules. On January 17, 1980, he visited our clinic first with a complaint of generalized convulsions. CT revealed multiple low-density areas. For the subsequent 4 years, the patient was followed-up by CT. Meanwhile, the cyst became large and was calcified; in addition, brain atrophy progressed, and a new lesion of the cyst appeared. Case 2: A 50-year-old man who had also lived in Korea and who had also eaten raw pork often. He had been diagnosed as having ''cestodiasis'' in a gastro-intestinal hospital 7 or 8 years before. He visited our clinic because of sensory aphasia which developed on January 15, 1980. CT disclosed multiple low-density areas and a calcification of the left cerebellar hemisphere. Ring enhancement was also found on enhanced CT. The patient was then surgically treated. The excised specimen contained a three-layer structure characteristic of cysticercosis. The immunoelectrophoresis of the cyst fluid gave a positive result for the disease. Postoperatively, the symptoms improved. Intracerebral cysticercosis is a very rare disease in Japan. Its incidence, however, is likely to increase on account of the development of transportation. For this reason, and because of the necessity to differentiate it from a brain tumor or abscess on CT, it seems that this disease is of concern. (author)

    1989-01-01

    CT-guided stereotactic operation was performed in 55 patients with hypertensive intracerebral hematoma. Location of the hematoma was putamen in 28 cases, thalamus in 14 cases, subcortical area in 9 cases, cerebellum in 3 cases and pons in one case. Ages ranged from 36 to 85 years (mean 59.5). The mean timing of the surgery after bleeding was 4.2 days. The estimated volume of the hematoma on CT was 8 ml to 57 ml in putaminal, 9 ml to 40 ml in thalamic, 18 ml to 77 ml in subcortical, 17 ml to 26 ml in cerebellar and 5 ml in pontine hemorrhage. Aspiration rate at surgery was 60.4% in putaminal, 37.9% in thalamic, 41.7% in subcortical, 45.2% in cerebellar and 30% in pontine hemorrhage. In addition, we evaluated ADL at 6 months postoperatively in patients with putaminal and thalamic hamorrhage. It is concluded that stereotactic operation is advisable in those cases with 10 to 50 ml hematoma volumes in putamen or thalamus. On the other hand, in cases with over 50ml volume, hematoma should be evacuated by craniotomy. (author)

    Objective: To evaluate the clinical application of CT-controlled stereotactic aspiration for intracerebral hematoma. Methods: CT-guided stereotactic system was installed on the CT bed, and checked against a standard of the coordinate. According to controlled CT scan, the target can be adjusted at any time in the operation. 860 patients with cerebral hematoma underwent CT-controlled stereotactic aspiration. Of the 860 cases, basal ganglion hematoma was present in 408, thalamus and posterior limb of internal capsule hematoma in 136, cerebral lobe hematoma in 261, cerebellar hematoma in 5, ventricular hemorrhage in 10, midbrain and pons hemorrhage in 37, and medulla hemorrhage in 3. Results: Easy drainage of hematoma by aspiration was achieved in 586 cases, stickiness of hematoma with clearing away more than 50% was performed in 202 and less than 50% in 68. The operation duration ranged from 25 to 120 minutes (average 45 minutes). 693 cases survived and 167 cases died. According to the evaluation by active day life (ADL) after 3 months in survivors, ADL 1-2, ADL 3, ADL 4 and ADL 5 results were achieved in 378 cases, 166 cases, 107 cases, and 28 cases, respectively. In addition, 14 cases were lost beyond recall. Conclusion: CT-controlled stereotactic aspiration for intracerebral hematoma is a handy, less invasive, and safe procedure with high accuracy and curative effect, it is worth while popularizing the procedure

This paper investigates the relationship between CSF and MIPS in monitoring of rabbit intracerebral hemorrhage models, which is based on the MIPS measurements data, the quantified data on CSF from medical images and the amount of injected blood in the rabbit intracerebral hemorrhage model. In the investigated results, a R value of 0.792 with a significance of 0.019 is observed between the MIPS and CSF, which is closer than MIPS and injected blood. Before the reversal point of MIPS, CSF is the leading factor in MIPS signal changing in an early hematoma expansion stage. Under CSF compensation, CSF reduction compensates for hematoma expansion in the brain to keep intracranial pressure stable. MIPS decrease results from the reducing CSF volume. This enables MIPS to detect hematoma expansion earlier than intracranial pressure.

    Objective: To analyze the clinical symptoms and CT manifestations of GCS 15 patients with intracranial hemorrhage. Methods: Clinical data and manifestations of the CT images of 35 patients with GCS 15 and intracranial hemorrhage were retrospectively analyzed and followed up. in short term. Results: Clinical symptoms: Deficits in short-term memory appeared in 17% of patients, vomiting in 26%, headache in 97%, physical evidence of trauma above the clavicles in 100%. CT scanning: intracerebral hemorrhage occurred in 18 patients, epidural hemorrhage in 9 patients, subarachnoid hemorrhage in 8 patients, subdural hemorrhage in 7 patients. During follow up, clinical severe degree was in consistent of craniocerebral CT scanning. Conclusion: For patients with GCS 15 brain injuries early head CT scanning is very important. Intracranial hemorrhage may occur in these patients. If possible, re-assessment of clinical examination and CT scanning is remarkably necessary. (authors)

    Computed Tomography has become increasingly important diagnostic method as the initial examination in the diagnosis of subarachnoid hemorrhage with direct detection of extravasated blood in basal cistern and cortical sulci. Furthermore, CT provides better and exact visualization of the presence, localization, extent and degree of intracerebral, intraventricular and subdural hemorrhage, infarction, hydrocephalus and rebleeding which may be associated with subarachnoid hemorrhage, and also could detect the causative lesions with contrast enhancement in many cases. The purpose of the paper is to describe the CT findings of subarachnoid hemorrhage due to various causes and to evaluate the diagnostic accuracy of CT in subarachnoid hemorrhage. Authors analysed a total of 153 cases with subarachnoid hemorrhage confirmed by lumbar puncture at Seoul National University Hospital from March 1979 to April 1981, with special emphasis on CT findings. All of the cases took CT scan and 125 cases of them angiography. The results are as follows: 1. Most prevalent age group was 4th to 6th decades (78%). The ratio of male to female was 1.1: 1. 2. Of 125 cases with angiography, aneurysm was a major cause (68%). Others were arterio-venous malformation (9.6%), Moya-moya disease (4%) and unknown (18.4%). 3. Of all 153 cases with CT scan, hemorrhage was demonstrated in 98 cases (64.1%); SAH in 72 cases (47.1%), ICH in 65 cases (42.5%), IVH in 34 cases (22.2%) and SDH in 1 case (0.7%). SAH combined with ICH was a major group (34.7%) in SAH. Detection rate of SAH was 68.3% within the first 7 days and 5.8% after 7 dyas. 4. In aneurysms, SAH was detected in 60 of 85 cases (70.6%); 88.1% within the first 7 dyas and 5.6% after 7 dyas. Anterior communicating artery was the most common site of the aneurysms (40%), in which detection rate of SAH was 100% within the first 7 days. SAH was combined with ICH in 38.3%. 5. On CT, SAH of unilateral Sylvian fissure was pathognomonic for ruptured MCA

    Intracerebral hemorrhage (ICH) can occur in patients following acute ischaemic stroke in the form of hemorrhagic transformation, and results in significant long-term morbidity and mortality. Anticoagulation theoretically increases risk. We evaluated stroke patients with an indication for anticoagulation to determine the factors associated with hemorrhagic transformation. Three-hundred and forty-five patients with ICD-9 codes indicating: (i) acute ischaemic stroke; and (ii) an indication for anticoagulation were screened. One-hundred and twenty-three met inclusion criteria. Data were collected retrospectively. Neuroimaging was reviewed for infarct volume and evidence of ICH. Hemorrhages were classified as: hemorrhagic conversion (petechiae) versus intracerebral hematoma (a space occupying lesion); symptomatic versus asymptomatic. Using multivariable logistic regression, we determined the hypothesized factors associated with intracerebral bleeding. Age [odds ratio (OR) = 1.50 per 10-year increment, 95% confidence interval (CI) 1.07-2.08], infarct volume (OR = 1.10 per 10 ccs, 95% CI 1.06-1.18) and worsening category of renal impairment by estimated glomerular filtration rate (eGFR; OR = 1.95, 95% CI 1.04-3.66) were predictors of hemorrhagic transformation. Ninety- nine out of 123 patients were anticoagulated. Hemorrhage rates of patients on and off anticoagulation did not differ (25.3% vs. 20.8%; P = 0.79); however, all intracerebral hematomas (n = 7) and symptomatic bleeds (n = 8) occurred in the anticoagulated group. The risk of hemorrhagic transformation in patients with acute ischaemic stroke and an indication for anticoagulation is multifactorial, and most closely associated with an individual's age, infarct volume and eGFR. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    Minocycline is under investigation as a neurovascular protective agent for stroke. This study evaluated the pharmacokinetic, anti-inflammatory, and safety profile of minocycline after intracerebral hemorrhage. This study was a single-site, randomized controlled trial of minocycline conducted from 2013 to 2016. Adults ≥18 years with primary intracerebral hemorrhage who could have study drug administered within 24 hours of onset were included. Patients received 400 mg of intravenous minocycline, followed by 400 mg minocycline oral daily for 4 days. Serum concentrations of minocycline after the last oral dose and biomarkers were sampled to determine the peak concentration, half-life, and anti-inflammatory profile. A total of 16 consecutive eligible patients were enrolled, with 8 randomized to minocycline. Although the literature supports a time to peak concentration (T max ) of 1 hour for oral minocycline, the T max was estimated to be at least 6 hours in this cohort. The elimination half-life (available on 7 patients) was 17.5 hours (SD±3.5). No differences were observed in inflammatory biomarkers, hematoma volume, or perihematomal edema. Concentrations remained at neuroprotective levels (>3 mg/L) throughout the dosing interval in 5 of 7 patients. In intracerebral hemorrhage, a 400 mg dose of minocycline was safe and achieved neuroprotective serum concentrations. However, oral administration led to delayed absorption in these critically ill patients and should not be used when rapid, high concentrations are desired. Given the safety and pharmacokinetic profile of minocycline in intracerebral hemorrhage and promising data in the treatment of ischemic stroke, intravenous minocycline is an excellent candidate for a prehospital treatment trial.

    1987-01-01

    Etiologic diagnosis of cerebromeningeal hemorrhage was suspected on CT scan without contrast imaging as a function of distribution of cisternal hyperdensities and/or topography of intracerebral hematomas and/or distribution of parenchymatous hypodensities. It was established in 90 % of cases by results of angioscan (type and site of vascular malformation causing the cerebromeningeal hemorrhage are defined with this percent exactitude). Cerebral arteriography provides indispensable precise morphologic data on the vascular malformation: exact site of aneurysm or arteriovenous malformation, orientation of the aneurysm and presence or absence of a collar. It is therefore irreplaceable and will be guided by data from the angio-CT scan [fr

    Malignant large artery stroke is associated with high mortality of 70% to 80% with best medical management. Decompressive craniectomy (DC) is a highly effective tool in reducing mortality. Convincing evidence has accumulated from several randomized trials, in addition to multiple retrospective studies, that demonstrate not only survival benefit but also improved functional outcome with DC in appropriately selected patients. This article explores in detail the evidence for DC, nuances regarding patient selection, and applicability of DC for supratentorial intracerebral hemorrhage and posterior fossa ischemic and hemorrhagic stroke.

    Sixty-one cases of hypertensive intracerebral hematoma were evacuated by CT guided stereotactic method. The operation was performed in the CT room under general anesthesia using the KOMAI-NAKAJIMA STEREOTACTIC DEVICE. This instrument has a micromanipulater that can be used for various kinds of stereotactic procedures. Three dimensional position of the target point (aspiration point of the hematoma) was determined on the film obtained from CT scanning of the patient in the stereotactic system. If the hematoma was small, the target point was enough to be one point at the center of the hematoma, but in case of the large hematoma, several target points were given according to the shape of hematoma. The probe, ordinarily a steel tube 4 mm in outer diameter, was inserted through brain to the target point and the hematoma was aspirated through a silicon tube connected to a vacuum system. Among 61 cases examined, 30 cases of thalamic hemorrhage were operated upon and 36 cases were not operated. They were classified according to the volume of hematoma into 3 groups as follows: A=less than 10 ml, B=11-25 ml, C=more than 25 ml. The operated cases were compared with the non operated cases on the improvement of consciousness in each group. In the A group, the operated patients in the level I recovered more slowly than the non operated patients, but in the level II patients, this was reversed. In the B group, the operated patients improved more quickly except the level I patients. In the C group, almost all of non operated patients died. Thus, this operation was very useful in improving consciousness of level II or III patients independent of hematoma volume. It accelerated the recovery of motor function in the level I. This non inversive technique is considered effective for the removal of deep intracerebral hematoma. (author)

    Evidence linking short-term exposure to outdoor air pollution with hemorrhagic stroke is inconsistent. We evaluated the associations between outdoor air pollution and specific types of stroke in Tokyo, Japan, from April 2003 to December 2008. We obtained daily counts of stroke mortality (n = 41,440) and concentrations of nitrogen dioxide as well as particles less than 2.5 μm in diameter. Time-series analysis was employed. Although same-day air pollutants were positively associated with ischemic stroke and intracerebral hemorrhage mortality, both air pollutants were more strongly associated with subarachnoid hemorrhage mortality: rate ratio was 1.041 (95% confidence interval: 1.011-1.072) for each 10 μg/m3 increase in the previous-day particles less than 2.5 μm. This study suggests that short-term exposure to outdoor air pollution increases the risks of hemorrhagic stroke mortality as well as ischemic stroke mortality.

    Objective: We aimed to detect the frequency of restricted diffusion in intracerebral metastases and to find whether there is correlation between the primary tumor pathology and diffusion-weighted MR imaging (DWI) findings of these metastases. Material and methods: 87 patients with intracerebral metastases were examined with routine MR imaging and DWI. 11 hemorrhagic metastatic lesions were excluded. The routine MR imaging included three plans before and after contrast enhancement. The DWI was performed with spin-echo EPI sequence with three b values (0, 500 and 1000), and ADC maps were calculated. 76 patients with metastases were grouped according to primary tumor histology and the ratios of restricted diffusion were calculated according to these groups. ADCmin values were measured within the solid components of the tumors and the ratio of metastases with restricted diffusion to that which do not show restricted diffusion were calculated. Fisher's exact and Mann-Whitney U tests were used for the statistical analysis. Results: Restricted diffusion was observed in a total of 15 metastatic lesions (19, 7%). Primary malignancy was lung carcinoma in 10 of these cases (66, 6%) (5 small cell carcinoma, 5 non-small cell carcinoma), and breast carcinoma in three cases (20%). Colon carcinoma and testicular teratocarcinoma were the other two primary tumors in which restricted diffusion in metastasis was detected. There was no statistical significant difference between the primary pathology groups which showed restricted diffusion (p > 0.05). ADCmin values of solid components of the metastasis with restricted diffusion and other metastasis without restricted diffusion also showed no significant statistical difference (0.72 {+-} 0.16 x 10{sup -3} mm{sup 2}/s and 0.78 {+-} 21 x 10{sup -3} mm{sup 2}/s respectively) (p = 0.325). Conclusion: Detection of restricted diffusion on DWI in intracerebral metastasis is not rare, particularly if the primary tumor is lung or breast

    We review recent progress in massive gravity. We start by showing how different theories of massive gravity emerge from a higher-dimensional theory of general relativity, leading to the Dvali–Gabadadze–Porrati model (DGP), cascading gravity, and ghost-free massive gravity. We then explore their theoretical and phenomenological consistency, proving the absence of Boulware–Deser ghosts and reviewing the Vainshtein mechanism and the cosmological solutions in these models. Finally, we present alt...

    Intracerebral hemorrhage is the most serious complication of cerebral arteriovenous malformations (AVM). To identify angiographic characteristics of AVM which correlate with a history of hemorrhage, we retrospectively analyzed angiographic findings of 25 patients with AVM. Nine characteristic were evaluated; these include nidus size, location, arterial aneurysm, intranidal aneurysm, angiomatous change, venous drainage pattern, venous stenosis, delayed drainage and venous ectasia. The characteristic were correlated with hemorrhage,which was seen in 18 (72%) patients on CT or MR images. Venous stenosis (P<0.5) and delaved venous drainage (P<0.5) well correlated with a history of hemorrhage. Arterial aneurysm and intranidal aneurysm also had a tendency hemorrhage although they did not prove to be statistically significant. Detailed analysis of angiographic finding of AVM is important for recognition of characteristic which are related to hemorrhage and may contribute to establishing a prognosis and treatment planning.

  18. Massive branes

    1998-01-01

    We investigate the effective world-volume theories of branes in a background given by (the bosonic sector of) 10-dimensional massive IIA supergravity (''''massive branes'''') and their M-theoretic origin. In the case of the solitonic 5-brane of type IIA superstring theory the construction of the Wess-Zumino term in the world-volume action requires a dualization of the massive Neveu-Schwarz/Neveu-Schwarz target space 2-form field. We find that, in general, the effective world-volume theory of massive branes contains new world-volume fields that are absent in the massless case, i.e. when the mass parameter m of massive IIA supergravity is set to zero. We show how these new world-volume fields can be introduced in a systematic way. (orig.)

    Moyamoya disease is a rare cerebrovascular anomaly involving the intracranial carotid arteries that can present clinically with either ischemic or hemorrhagic disease. Moyamoya syndrome, indistinguishable from moyamoya disease at presentation, is associated with multiple clinical conditions including neurofibromatosis type 1, autoimmune disease, prior radiation therapy, Down syndrome, and Turner syndrome. We present the first reported case of an adult patient with previously unrecognized mosaic Turner syndrome with acute subarachnoid and intracerebral hemorrhage as the initial manifestation of moyamoya syndrome. A 52-year-old woman was admitted with a subarachnoid hemorrhage with associated flame-shaped intracerebral hemorrhage in the left frontal lobe. Physical examination revealed short stature, pectus excavatum, small fingers, micrognathia, and mild facial dysmorphism. Cerebral angiography showed features consistent with bilateral moyamoya disease, aberrant intrathoracic vessels, and an unruptured 4-mm right superior hypophyseal aneurysm. Genetic analysis confirmed a diagnosis of mosaic Turner syndrome. Our case report is the first documented presentation of adult moyamoya syndrome with subarachnoid and intracerebral hemorrhage as the initial presentation of mosaic Turner syndrome. It illustrates the utility of genetic evaluation in patients with cerebrovascular disease and dysmorphism. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

    Nattokinase is used as a health-promoting medicine for preventing thrombosis due to its fibrinolytic activity. Cerebral microbleed is remnant of blood extravasations from the damaged vessels related to cerebral microangiopathies. We report a patient, having used aspirin for secondary stroke prevention, who had an acute cerebellar hemorrhage after taking nattokinase 400 mg daily for 7 consecutive days. In addition to the hemorrhagic lesion, multiple microbleeds were demonstrated on brain MR images. We suggest that nattokinase may increase risk of intracerebral hemorrhage in patients who have bleeding-prone cerebral microangiopathy and are receiving other antithrombotic agent at the same time.

    Hospitalizations for pregnancy-related stroke are rare but increasing. Hemorrhagic stroke (HS), ie, subarachnoid hemorrhage and intracerebral hemorrhage, is more common than ischemic stroke in pregnant versus nonpregnant women, reflecting different phenotypes or risk factors. We compared stroke risk factors and outcomes in pregnant versus nonpregnant HS in the Get With The Guidelines-Stroke Registry. Using medical history or International Classification of Diseases-Ninth Revision codes, we identified 330 pregnant and 10 562 nonpregnant female patients aged 18 to 44 years with HS in Get With The Guidelines-Stroke (2008-2014). Differences in patient and care characteristics were compared by χ(2) or Fisher exact test (categorical variables) or Wilcoxon rank-sum (continuous variables) tests. Conditional logistic regression assessed the association of pregnancy with outcomes conditional on categorical age and further adjusted for patient and hospital characteristics. Pregnant versus nonpregnant HS patients were younger with fewer pre-existing stroke risk factors and medications. Pregnant versus nonpregnant subarachnoid hemorrhage patients were less impaired at arrival, and less than half met blood pressure criteria for severe preeclampsia. In-hospital mortality was lower in pregnant versus nonpregnant HS patients: adjusted odds ratios (95% CI) for subarachnoid hemorrhage 0.17 (0.06-0.45) and intracerebral hemorrhage 0.57 (0.34-0.94). Pregnant subarachnoid hemorrhage patients also had a higher likelihood of home discharge (2.60 [1.67-4.06]) and independent ambulation at discharge (2.40 [1.56-3.70]). Pregnant HS patients are younger and have fewer risk factors than their nonpregnant counterparts, and risk-adjusted in-hospital mortality is lower. Our findings suggest possible differences in underlying disease pathophysiology and challenges to identifying at-risk patients. © 2015 American Heart Association, Inc.

    Full Text Available Background:High resolution CT scan has made early diagnosis of intraventricular hemorrhage (IVH easier. Posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the CT scan. Methods:904 patients were admitted in the NSICU from March 2001 to March 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (GCS less than 8 are reported herein and the mechanism involved is discussed. Results: Nine cases had intracerebral hemorrhage (contusional group, four cases in the frontal lobe, three cases in the temporal lobe and two cases in the parietal lobe. Nine cases (basal ganglia hemorrhage group had hemorrhage in basal ganglia, six in the caudate nucleus and three in the thalamus, all spreading into the ventricles. In thirteen cases the original site of hemorrhage could not be determined. In this group six cases had accompanying peri-brain stem hemorrhage (peri-brain stem hemorrhage group and different brain stem injury signs. Four cases had IVH less than 5 mL with or without minor intracranial lesions (minor intracranial lesion group. Accompanying major intracranial hemorrhage was found in sixteen cases, six cases had epidural hematoma, four cases had subdural hematoma, and seven had a combination of ASDH, EDH and contusional prarenchymal hemorrhages, all requiring primary surgical evacuation, and seven cases had different degrees of minor abnormalities (i.e. minor epidural hemorrhage, minor subdural hemorrhage,sub-arachnoid hemorrhage, minor cortical contusions or subdural effusions which did not need surgical intervention.Two cases had acute hydrocephalus and needed ventricular external drainage. Conclusion:Acceleration-deceleration impact along the long axis of the skull might be the possible mechanism in shearing injury to perforating vessels of the basal ganglia for early appearance of hemorrhage in the caudate nucleus and thalamus.

    The author analysed experience in the embolization of the abdominal vessels in 79 patients with diseases and lesions of the peritoneal cavity and retroperitoneal space accompanied by life threatening hemorrhage. In 51 cases embolization was used as an independent method of hemorrhage arrest and in 28 cases for patients' preoperative preparation. A hemostatic sponge combined with a superselective administration of 150-200 ml of aminocaproic acid was used as an emboilizing material. Complications attributed to embolization were noted in 5 patients: pancreatitis, subdiaphragmatic abscess, paranephritis, ischemia of the gluteal soft tissues, sciatic neuritis.

    Objective Aneurysm clipping and simultaneous hematoma evacuation through open craniotomy is traditionally recommended for ruptured cerebral aneurysms accompanied by intracerebral or intrasylvian hemorrhages. We report our experience of adapting a less invasive treatment strategy in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms, where the associated ruptured cerebral aneurysms were managed by endovascular coil embolization, followed by stereotactic aspiration of hematomas (SRH) using urokinase. Materials and Methods We retrospectively analyzed 112 patients with ruptured cerebral aneurysms. There were accompanying intracerebral or intrasylvian hemorrhages in 36 patients (32.1%). The most common site for these ruptured aneurysms was the middle cerebral artery (MCA) (n = 15; 41.6%). Endovascular coil embolization followed by SRH using urokinase was performed in 9 patients (25%). Results In these 9 patients, the most common site of aneurysms was the MCA (n = 3; 33.4%); the hematoma volume ranged from 19.24 to 61.68 mL. Four patients who were World Federation of Neurological Surgeons (WFNS) grade-IV on admission, achieved favorable outcomes (Glasgow Outcome Score [GOS] 4 or 5) at 6-months postoperatively. In the five patients who were WFNS grade-V on admission, one achieved a favorable outcome, whereas 4 achieved GOS scores of 2 or 3, 6-months postoperatively. There was no mortality. Conclusion If immediate hematoma evacuation is not mandated by clinical or radiological signs of brain herniation, a less invasive strategy, such as endovascular coil embolization followed by SRH using urokinase, may be a good alternative in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms.

    To investigate the changes of Apo-J and Omi/HtrA2 protein expression in rats with intracerebral hemorrage. 150 SD adult rats were randomly divided into 3 groups: (1) Normal Control (NC) group, (2) Sham group, (3) Intracerebral Hemorrage (ICH) group. The data were collected at 6h, 12h, 1d, 2d, 3d, 5d and 7d. Apoptosis was measured by Tunel staining. The distributions of the Apo-J and Omi/HtrA2 proteins were determined by immunohistochemical staining. The levels of Apo-J mRNA and Omi/HtrA2 mRNA expressions were examined by RT-PCR. Apoptosis in ICH group was higher than Sham and NC groups (p<0.05). Both the Apo-J and Omi/HtrA2 expression levels were increased in the peripheral region of hemorrhage, with a peak at 3d. The Apo-J mRNA level positively correlated with HtrA2 mRNA level in ICH group (r=0.883, p<0.001). The expressions of Apo-J and Omi/HtrA2 paralelly increased in peripheral region of rat cerebral hemorrhage. Local high expressed Apo-J in the peripheral regions might play a neuroprotective role by inhibiting apoptosis via Omi/HtrA2 pathway after hemorrhage. Copyright © 2018. Published by Elsevier Inc.

    Twenty-three intracerebral hemorrhages (ICH) were seen in 60 neonates. Both T1- weighted (spin-echo, repetition time/echo time = 600-800/20 msec) and heavily T2- weighted sequences (SE = 2,500/80, 160) were necessary for detecting hemorrhage. MR imaging failed to disclose seven of ten IVH because of an irregular and full choroid, seen on US. US failed to show six ICH because of their small size (≤0.5 cm) or peripheral site. Twelve extracerebral hemorrhages were missed on US, and only one of three was seen on CT. In five other cases there were signal features of hemosidering from earlier hemorrhage. MR imaging is the best modality for visualizing ICH because of its high sensitivity, specificity, and the persistence of hemorrhagic signal for weeks to months longer than on US or CT

    Even before the introduction of CT we reported that the intracranial hemorrhage in Moyamoya disease was not subarachnoid hemorrhage but intraventricular hemorrhage and that the bleeding point was the paraventricular subependymal region of lateral ventricles; these findings were based on our experience with three Moyamoya cases in which ventricular hemorrhage occurred and pseudoaneurysms were revealed in the territory of the posterior choroidal artery. Twelve cases with intracranial hemorrhage caused by Moyamoya disease have now been studied by CT in order to determine (1) whether the hemorrhage is subarachnoid or intraventricular, and (2) where the bleeding point is. In the results for the eight cases for which the CT scan was performed within one day after the onset, intraventricular hemorrhage was shown in all cases. The bleeding point was examined in twelve cases; in four cases it was recognized by initial CT only, but if five cases in which ventricular hemorrhage only appeared in the initial CT,follow-up plain and contrast-enhanced CT were necessary. In a total of nine cases, then, bleeding points were recognized. In one case putaminal hemorrhage penetrated into the lateral ventricle, while in eight cases the intracerebral hematoma was located in the paraventricular region of the lateral ventricle, such as at the head of the caudate nucleus or the thalamus. In some cases, small subependymal hematoma projected into the lateral ventricle. In cases with symptoms of intracranial hemorrhage at the onset, the bleeding points were at the paraventricular parenchyma of the lateral ventricle in almost all cases. (author)

    Intracranial hemorrhages in perinatal babies and their sequelae are two of the targets of recent investigations. This study was designed to make clear the correlation between intracranial hemorrhage in perinates and the sequential widening of the cerebrospinal fluid space, including ventricles. 600 cases with moderate or severe clinical symptoms were treated in the Neonatal Intensive Care Unit of the Toho University Hospital from February, 1981, to October, 1982. Of these, 137 cases were suspected clinically to have had an intracranial hemorrhage at birth. In the CT study of these cases, intracranial hemorrhages of various types were confirmed in 55 cases. These included subarachnoid hemorrhages (29 cases), intraventricular hemorrhages (3 cases), intracerebral hemorrhages (3 cases), and combined hemorrhages (20 cases). A follow-up check of these cases by means of CT scan and neurological examinations was done for a period of from 40 days to 20 months. In 35 cases (63.5%) out of the 55, a temporary or persistent enlagement of the ventricle and/or widenings of the CSF space of various types were demonstrated. The latter included subdural effusion, the widening of the Sylvian fissure and/or interhemispheric fissure, and the widening of the basal cisterns. An enlargement of the ventricle occurred often following an intraventricular or intracerebral hemorrhage. On the other hand, subdural effusion was a common sequela after a subarachnoid hemorrhage. These changes in the ventricle or CSF space seem to be benign in nature and were improved in most cases during the period of the follow-up study. The ventricular enlargement disappeared substantially in 5 cases, and in the remaining 30 cases the abnormalities on the CT scans were much improved. Clinically, retarded physical development was evident in 3 cases, but the others showed no developmental retardation

    Despite the literature's emphasis on the presence of intracerebral vascular malformations in hereditary hemorrhagic telangiectasia (HHT), few cases have been documented. The authors prospectively evaluated brain CT scans in 29 consecutive patients with pulmonary arteriovenous malformations (AVMs) and known HHT. Fifty-five percent of the CT scans revealed the signs of embolic phenomena: infarctions (n=11) and intracerebral abscesses (n=5). In only one patient was a small enhancing vascular lesion seen. They conclude that embolic phenomena rather than vascular malformations cause the majority of abnormal CT findings in patients with HHT and pulmonary AVMs. Infarctions and intracerebral abscesses probably result from paradoxical embolization through the AVMs in the lungs. The therapeutic implications seem clear, since 55% of these patients are potentially treatable by balloon occlusion of the pulmonary AVMs

    ABSTRACT : INTRODUCTION : The massive-transfusion concept was introduced to recognize the dilutional complications resulting from large volumes of packed red blood cells (PRBCs). Definitions of massive transfusion vary and lack supporting clinical evidence. Damage-control resuscitation regimens...... of modern trauma care are targeted to the early correction of acute traumatic coagulopathy. The aim of this study was to identify a clinically relevant definition of trauma massive transfusion based on clinical outcomes. We also examined whether the concept was useful in that early prediction of massive...... transfusion as a concept in trauma has limited utility, and emphasis should be placed on identifying patients with massive hemorrhage and acute traumatic coagulopathy....

    Perinatal stroke leads to significant morbidity and long-term neurological and cognitive deficits. The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. To understand whether microglial cells limit injury after neonatal stroke by preserving neurovascular integrity, we subjected postnatal day 7 (P7) rats depleted of microglial cells, rats with inhibited microglial TGFbr2/ALK5 signaling, and corresponding controls, to transient middle cerebral artery occlusion (tMCAO). Microglial depletion by intracerebral injection of liposome-encapsulated clodronate at P5 significantly reduced vessel coverage and triggered hemorrhages in injured regions 24 h after tMCAO. Lack of microglia did not alter expression or intracellular redistribution of several tight junction proteins, did not affect degradation of collagen IV induced by the tMCAO, but altered cell types producing TGFβ1 and the phosphorylation and intracellular distribution of SMAD2/3. Selective inhibition of TGFbr2/ALK5 signaling in microglia via intracerebral liposome-encapsulated SB-431542 delivery triggered hemorrhages after tMCAO, demonstrating that TGFβ1/TGFbr2/ALK5 signaling in microglia protects from hemorrhages. Consistent with observations in neonatal rats, depletion of microglia before tMCAO in P9 Cx3cr1(GFP/+)/Ccr2(RFP/+) mice exacerbated injury and induced hemorrhages at 24 h. The effects were independent of infiltration of Ccr2(RFP/+) monocytes into injured regions. Cumulatively, in two species, we show that microglial cells protect neonatal brain from hemorrhage after acute ischemic stroke. Copyright © 2016 the authors 0270-6474/16/362881-13$15.00/0.

    We investigated the usefulness of echo-planar imaging (EPI) as well as T2{sup *}-weighted and diffusion-weighted MRI (DWI) to identify hyperacute hemorrhage (within 24 h after ictus) in the brain. Seven patients were examined 3.5 to 24 h after onset of symptoms using a whole-body 1.5-T MR system. Two diffusion-weighted sequences were run to obtain isotropic and anisotropic diffusion images. Apparent diffusion coefficients (ADC) were calculated from the isotropic diffusion images. All DWI images as well as the T2*-weighted EPI images showed the hematomas as either discrete, deeply hypointense homogeneous lesions, or as lesions of mixed signal intensity containing hypointense areas. We conclude that even in the early phase after hemorrhage, sufficient amounts of paramagnetic deoxyhemoglobin are present in intracerebral hemorrhages to cause hypointensity on EPI T2{sup *}-weighted and DWI images; thus, use of ultrafast EPI allows identification of intracerebral hemorrhage.

    Intracerebral capillary hemangiomas are very rare benign vascular tumors that mostly occur during infancy. We described a 69-year-old man with generalized tonic-clonic seizures who was diagnosed with an intracranial mass. Multidetector computed tomography, magnetic resonance imaging and digital subtraction angiography studies were performed for evaluation of brain, and there was a well-enhancing mass found in the right temporal lobe without a definite feeding vessel. The patient underwent surgery and the pathologic examination demonstrated marked proliferation of small vessels with a lobular pattern in the brain parenchyma, which was confirmed to be capillary hemangioma.

    In the past six years, we have had experience with 40 patients with hypertensive thalamic hemorrhages, as verified by CT scan at our hospital within 24 hours. These patients were classified into the following three groups according to the location of the bleeding point and the size of the hematoma: (1) anteromedial (4 cases), (2) posterolateral (16 cases), and (3) massive (20 cases). The (1) and (2) hematomas were small (less than 3 cm in diameter), while those in (3) were large (more than 3 cm in diameter). Twenty cases (50% of all the thalamic hematomas) were small hematomas. The characteristic clinical symptoms of the anteromedial type were a mild disturbance of consciousness and thalamic dementia, while those of the posterolateral type were motor and sensory disturbance, and thalamic aphasia, respectively. Twenty cases (50%) were large hematomas. The clinical symptoms of these cases were mainly consciousness disturbance; 7 of them expired. Based on this experience, it may be considered that the patients whose hematoma size was larger than 3 cm had a poor prognosis and that the patients with the posterolateral type had a poor functional diagnosis.

    The clinical and CT findings in 10 patients with primary pontine hemorrhage were reviewed. All patients were hypertensive. Pontine hemorrhage can be divided into 3 groups from the viewpoint of location of hematomas. These are the tegmentobasilar type, tegmental type and basilar type. The tegmentobasilar type produces characteristic clinical features for pontine hemorrhage and poor prognosis, otherwise, another two types produce atypical clinical features for pontine hemorrhage and good prognosis.

    Recently, CT-guided stereotactic aspiration has been attempted as a useful method for hypertensive intracerebral hemorrhage. Since the CT scanner was introduced in our clinic, we have experienced 55 cases with hypertensive pontine hemorrhage. We carried out stereotactic aspiration in nine cases consisting of four men and five women, ranging in age from 34 to 66 years. Operation was performed between 4 and 22 days after the hemorrhage (mean: 7.7 days). On the other hand, 46 cases were conservatively treated. They consisted of 31 men and 15 women, aged from 31 to 79 years, with a mean age of 55.5 years. The purpose of this study is to review the outcome at three months after the onset, and then to evaluate the clinical value of this method for hypertensive pontine hemorrhage. We have analyzed the outcome from the viewpoint of consciousness level, CT classification, and maximum transverse hematoma diameter on CT scan. In the present study, there was a statistically significant correlation between consciousness level and outcome in the conservative group. The outcome in the operated-on group tended to be superior to that in the conservatively treated group. Particularly, in cases of Japan Coma Scale 10 to 100, functionally favorable effects were considered to be obtained by stereotactic aspiration. According to CT classification, operation was considered to have exerted functionally favorable effects on unilateral basis tegmentum type and bilateral tegmentum type. The conservatively treated group showed a statistically significant correlation between maximum transverse hematoma diameter and outcome. A favorable prognosis was considered to be induced by operation in cases of 22 to 28 mm in maximum transverse hematoma diameter. (author)

    Chronic subdural hematoma (CSDH) and symptomatic subdural hygroma are common diseases that require neurosurgical management. Burr hole trephination is the most popular surgical treatment for CSDH and subdural hygroma because of a low recurrence rate and low morbidity compared with craniotomy with membranectomy, and twist-drill craniotomy. Many reports suggest that placing a catheter in the subdural space for drainage can further reduce the rate of recurrence; however, complications associated with this type of drainage include acute subdural hematoma, cortical injury, and infection. Remote hemorrhage due to overdrainage of cerebrospinal fluid (CSF) is another possible complication of burr hole trephination with catheter drainage that has rarely been reported. Here, we present 2 cases of remote hemorrhages following burr hole trephination with catheter drainage for the treatment of CSDH and symptomatic subdural hygroma. One patient developed intracerebral hemorrhage and subarachnoid hemorrhage in the contralateral hemisphere, while another patient developed remote hemorrhage 3 days after the procedure due to the sudden drainage of a large amount of subdural fluid over a 24-hour period. These findings suggest that catheter drainage should be carefully monitored to avoid overdrainage of CSF after burr hole trephination.

    Accurate diagnosis of intracranial hemorrhage represents a frequent challenge for the practicing radiologist. The purpose of this article is to provide the reader with a synoptic overview of the imaging characteristics of intracranial hemorrhage, using text, tables, and figures to illustrate time-dependent changes. We examine the underlying physical, biological, and biochemical factors of evolving hematoma and correlate them with the aspect on cross-sectional imaging techniques. On CT scanning, the appearance of intracranial blood is determined by density changes which occur over time, reflecting clot formation, clot retraction, clot lysis and, eventually, tissue loss. However, MRI has become the technique of choice for assessing the age of an intracranial hemorrhage. On MRI the signal intensity of intracranial hemorrhage is much more complex and is influenced by multiple variables including: (a) age, location, and size of the lesion; (b) technical factors (e.g., sequence type and parameters, field strength); and (c) biological factors (e.g., pO2, arterial vs venous origin, tissue pH, protein concentration, presence of a blood-brain barrier, condition of the patient). We discuss the intrinsic magnetic properties of sequential hemoglobin degradation products. The differences in evolution between extra- and intracerebral hemorrhages are addressed and illustrated.

    Full Text Available Seventy patients with hemorrhagic stroke were prospectively evaluated regarding the electrocardiographic abnormalities observed within the first 48 hours of the ictus. Group I comprised 55 patients with spontaneous cerebral hemorrhage, and group II 15 patients with subarachnoid hemorrhage. Patients taking cardiac drugs (beta blockers, calcium-channel blockers, inotropic drugs or with severe metabolic/electrolyte disturbances were excluded. The most common ECG abnormality was a prolonged Q-Tc interval: group I, 37 (67.2%; group II, 8 (53.3%. Only 4 (7.2% patients of group I and no patient of group II had a normal ECG. No relation was found between the site of the intracerebral hematoma and the occurrence of any particular ECG change. A prolonged Q-Tc may be related to the development of severe cardiac arrhythmias observed in some patients with acute cerebral hemorrhage.

    : Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

    This study was developed to assess the role of magnetic resonance (MR) imaging in the diagnosis of cerebral arteriovenous malformations (AVMs) associated with hemorrhage. MR images were retrospectively reviewed in 10 patients (age 8 to 60 years) who had an AVM with intracerebral or intraventricular hemorrhage. MR imaging was performed at 1.5 T obtaining T{sub 1}- and T{sub 2}-weighted spin-echo images with a slice thickness of 5 mm, and a slice interval of 0-5 mm. The AVM was detected on MR in seven patients (70%), while enhanced CT was positive in six of eight patients (75%). In six patients in whom both the AVM and intracerebral hematoma (ICH) were depicted on MR, the nidi were located not inside but adjacent to the ICH. In three patients, MR disclosed a thin subdural hematoma (SDH) which was not noted on CT. There is little difference in the detectability of AVMs by MR and enhanced CT. However, MR clearly demonstrates the anatomic relationship to associated ICH. A non-traumatic SDH with an ICH demonstrated on MR may indicate the presence of an AVM even when the AVM itself is not apparent. (author).

    Full Text Available Yen-Michael S Hsu,1 Thorsten Haas,2 Melissa M Cushing1 1Department of Pathology and Laboratory Medicine, Weill Cornell Medical College, New York, NY, USA; 2Department of Anesthesia, University Children's Hospital Zurich, Zurich, Switzerland Abstract: Massive transfusion protocols (MTPs are established to provide rapid blood replacement in a setting of severe hemorrhage. Early optimal blood transfusion is essential to sustain organ perfusion and oxygenation. There are many variables to consider when establishing an MTP, and studies have prospectively evaluated different scenarios and patient populations to establish the best practices to attain improved patient outcomes. The establishment and utilization of an optimal MTP is challenging given the ever-changing patient status during resuscitation efforts. Much of the MTP literature comes from the trauma population, due to the fact that massive hemorrhage is the leading cause of preventable trauma-related death. As we come to further understand the positive and negative clinical impacts of transfusion-related factors, massive transfusion practice can be further refined. This article will first discuss specific MTPs targeting different patient populations and current relevant international guidelines. Then, we will examine a wide selection of therapeutic products to support MTPs, including newly available products and the most suitable of the traditional products. Lastly, we will discuss the best design for an MTP, including ratio-based MTPs and MTPs based on the use of point-of-care coagulation diagnostic tools.

    Simple prepatellar bursitis is easily diagnosed both clinically and by MRI. MRI shows the typical T1 and T2 lengthening of fluid within the bursa. However, because of complex MRI appearance of hemorrhage, chronic hemorrhagic bursitis and the size of the prepatellar mass the clinical and MRI appearance can be very different. (orig.)

    Erve virus (ERVEV) is a European Nairovirus that is suspected to cause severe headache (thunderclap headache) and intracerebral hemorrhage. The mode of transmission to humans (ticks or mosquitoes) is still unknown. Currently, no standardized testing method for ERVEV exists and only a small partial sequence of the polymerase gene is available. Here, we present the first complete genome sequence of ERVEV S, M, and L segments. Phylogenetic comparison of the amino acid sequence of the L-protein (...

    Cysticercosis is a parasitic disease in which man serves as the intermediate host of Taenia Solium, the pork tapeworm. The computed tomographic findings of 25 cases of intracerebral cysticercosis proven by pathologic and/or clinical findings during past 2 years were analysed. The results were as follows; 1. The sex was 19 males and 6 females, and 56 percent of the patients were seen in fourth and fifth decades. The most common symptom was epilepsy (72%). 2. The C. T. findings in precontrast study were varied; such as ill defined low density (48%), cystic low density (20%), dilated ventricles (20%), ill defined low density with isodense nodule (18%), cystic low density with isodense mural nodule (12%) and calcification (8%). 3. The areas of involvement were 20 cases (80%) of parenchymal form, 3 cases (12%) of ventricular form and 2 cases (8%) of mixed form. 4. The contrast-enhanced 13 cases were 5 nodular, 5 ring or rim-like and 3 mixed type enhancements, while 12 cases were not enhanced. 5. C.T. scan demonstrated more precise location and extents of cerebral cysticercosis, especially in parenchymal form. It was considered to be important in determination of surgical feasibility and its approach.

    Full Text Available The Shaken Baby Syndrome (SBS is characterized by subdural hematomas (SH, retinal hemorrhages (RH, and multiple fractures of long bones without external evidence of head trauma. Subinternal limiting membrane (ILM hemorrhage, also known as macular schisis, is a characteristic finding of this entity. There is no guideline on the right time to indicate surgical treatment. This report describes an abused child with massive sub-ILM hemorrhage, which showed spontaneous absorption after less than two months of follow-up. Due to the possible spontaneous resolution, we suggest an initial conservative treatment in cases of sub-ILM hemorrhage related to SBS.

    Conclusions: The MAC of SBP is associated with hematoma growth, and SD and COV are correlated with 3-month poor outcome in patients with supratentorial nonlobar ICH. Therefore, sustained SBP control, with a reduction in SBP variability is essential to reinforce the beneficial effect of intensive antihypertensive treatment.

    Full Text Available Bone marrow stromal cells (BMSCs may differentiate into nerve cells under a certain condition; however, the clinical application for treating nervous system disease remains unclear. The aim is to assess the safety profile, feasibility, and effectiveness of surgery combined with autologous BMSCs transplantation for treating ICH. 206 ICH patients who had received surgical procedure were divided into transplantation (n=110 or control group (n=96. For transplantation group, BMSCs were injected into the perihemorrhage area in the base ganglia through an intracranial drainage tube 5.5 (3.01–6.89 days after surgery, followed by a second injection into the subarachnoid space through lumbar puncture 4 weeks later. Neurologic impairment and daily activities were assessed with National Institute Stroke Scale (NIHSS, Barthel index, and Rankin scale before transplantation and 6 months and 12 months after transplantation. Our results revealed that, compared with control group, NIHSS score and Rankin scale were both significantly decreased but Barthel index was increased in transplantation group after 6 months. Interestingly, no significant difference was observed between 12 months and 6 months. No transplantation-related adverse effects were investigated during follow-up assessments. Our findings suggest that surgery combined with autologous BMSCs transplantation is safe for treatment of ICH, providing short-term therapeutic benefits.

    To describe two patients who developed an intracranial hematoma as a complication of temporal lobe encephalitis due to herpes simplex type 1 virus, and to review the literature. The first patient, a 45-year-old woman developed a brain hematoma in the location of the encephalitic lesion on day 9 after the onset of herpes simplex encephalitis (HSE) that required surgical evacuation. The second patient, a 53-year-old woman was being treated for HSE; on day 8 after admission a temporal lobe hematoma with midline shift was disclosed due to persistent headache. Both patients survived but were left with sequelae. We conducted a PubMed/MEDLINE search from 1986 to April 2013 on this topic. We have found 20 additional cases reported in the literature and review their characteristics. Hemorrhage was present on admission in 35% of pooled patients, and consistently involved the area of encephalitis. Clinical presentation of intracranial hemorrhage overlapped the encephalitic symptoms in two-thirds of the patients. Half of patients underwent surgery. Overall, mortality rate was low (5.2%), and half of patients fully recovered. Intracranial bleeding, although infrequent, can complicate the evolution of herpes simplex encephalitis and should be borne in mind since its presence may require neurosurgery. Although its presentation may overlap the encephalitic features, the lack of improvement or the worsening of initial symptoms, particularly during the second week of admission, should lead to this suspicion and to perform a neuroimaging study.

    Cogenital hydrocephalus is caused by a broad spectrum of underlying disorders. In the majority of cases it is due to aqueductal stenosis and other distinct congenital anomalies, like Arnold-Chiari malformation. Nevertheless, in the differential diagnosis rare conditions such as cerebral malignancies must also be considered. We present two cases of congenital intracerebral teratoma as a differential diagnosis in congenital obstructive hydrocephalus. A teratoma is suggested when a rapidly growing hydrocephalus with a central calcified and vascularized mass is found sonographically. Regular cerebral structures using cannot be detected. Early diagnosis in such cases is of clinical importance as the prognosis of congential intracerebral teratoma is generally very poor. (orig.)

    There is a lack of evidence to compare in-hospital mortality with different types of stroke. The purpose of this study was to elucidate the in-hospital mortality after acute ischemic/hemorrhagic stroke and compare the factors associated with the mortality among stroke subtypes. All patients admitted to Kurashiki Central Hospital in Japan between January 2009 and December 2009, and diagnosed with acute ischemic/hemorrhagic stroke were included in this study. Demographics and clinical data pertaining to the patients were obtained from their medical records. Out of 738 patients who had an acute stroke, 53 (7.2%) died in the hospital. The in-hospital mortality was significantly lower in the cerebral infarction group than in the intracerebral hemorrhage and subarachnoid hemorrhage group (3.5%, 15.1%, and 17.9%, respectively; Phemorrhage group than in the other 2 groups. With regard to past history, diabetes mellitus was significantly found to be a complication in mortality cases of intracranial hemorrhage. Further investigation is needed to clarify the effect of diabetes on mortality after intracranial hemorrhage.

    Objective: To assess whether statin treatment before or after acute ischemic stroke (AIS) affects the risk of acute intracerebral hemorrhage (ICH), postacute ICH, and mortality within 90 days. Methods: Data were sought from the Virtual International Stroke Trials Archive, an international repository of clinical trials data. Using propensity score matching, we retrospectively compared patients with prior statin treatment and newly initiated statin within 3 days after AIS to patients without statin exposure. Outcomes of interest were acute symptomatic ICH (sICH), any acute ICH, postacute ICH, and mortality during follow-up of 3 months. Results: A total of 8,535 patients (mean age 70 years, 54% male, median baseline NIH Stroke Scale score 13) were analyzed. After propensity score matching, prior statin use was not strongly associated with sICH (adjusted odds ratio [OR] 1.33, 95% confidence interval [CI] 0.83–2.14) or any ICH (adjusted OR 1.35, 95% CI 0.92–1.98). There was no evidence of an interaction between prior statin use and thrombolysis. New initiation of statins was not associated with postacute ICH (adjusted hazard ratio [HR] 1.60, 95% CI 0.70–3.65). There was a signal towards lower 90-day mortality in patients with prior statin use (adjusted HR 0.84, 95% CI 0.70–1.00) and especially early initiation of statins (adjusted HR 0.67, 95% CI 0.46–0.97). Conclusions: Statin use prior to AIS was not associated with early hemorrhagic complications, irrespective of treatment with thrombolysis. New initiation of statin treatment early after AIS did not affect risk of postacute ICH, but might be associated with reduced mortality. PMID:27016519

    Rebound of disease activity in multiple sclerosis patients after natalizumab withdrawal is a potentially life-threatening event. To verify whether highly destructive inflammation after natalizumab withdrawal is associated with Epstein-Barr virus (EBV) reactivation in central nervous system infiltrating B-lineage cells and cytotoxic immunity, we analyzed post-mortem brain tissue from a patient who died during a fulminating MS relapse following natalizumab withdrawal. Numerous EBV infected B cells/plasma cells and CD8+ T cells infiltrated all white matter lesions; the highest frequency of EBV lytically infected cells and granzyme B+ CD8+ T cells was observed in actively demyelinating lesions. These results may encourage switching to B-cell depleting therapy after natalizumab discontinuation. Copyright © 2017 Elsevier B.V. All rights reserved.

    Tumor hemorrhage on computed tomography (CT) was found in 14 patients with brain metastases (7 % of two hundred patients with brain metastases), from April 1979 to July 1983. Primary foci of these lesions were the lung (6 patients), breast (2), kidney (2), uterus (2), colon (1) and adrenal gland (1). ''Stroke'' syndrome was the initial presenting symptom in 3 patients; neurological focal sign or symptoms of increased intracranial pressure in the remaining patients. CT demonstrated peritumoral hemorrhage in all patients with solid mass, intratumoral hemorrhage in a few patients and also cerebral or ventricular hemorrhage, which was fatal complication, in 2 patients (colon and breast cancers). A cystic mass with fluid-blood level was noted in a patient with breast cancer. Several predisposing factors including chemotherapy, thrombocytopenia, radiotherapy or combination of these were recognized in 8 patients. Of these, chemotherapy was the most causative factor of tumor hemorrhage. Brain irradiation for hemorrhagic brain metastases was effective for prolongation of mean survival time of these patients as follows; 10 months in irradiated group, whereas 1.5 months in non-irradiated group.

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

    Before the introduction of computerized tomography (CT) there were some cases of intracerebral bleeding who were wrongly diagnosed as hypertensive encephalopathy or senile psychosis. We here report 5 cases who did not show any sign of motor paralysis. The clinical aspects of these cases were nausea and vomiting with dizziness (case 1), nausea and vomiting with slight headache (case 2), agnosia of left side with several kinds of disorientation (case 3), nausea and vomiting (case 4), and visual disturbance of right, lower quadrant (case 5). All of these cases showed no motor paralysis or abnormal reflex activities. By examination with CT each of them exhibited a high density area in the subcortical area of the right parietal lobe, the subcortical area of the right occipital lobe, the right temporal and parietal lobe, rather small portion of the left putamen and external capsule, and the subcortical area of left occipital lobe, respectively. Patients of cerebral hemorrhage without motor or sensory disturbances might often be taken for some psychic abnormality. We here have emphasized the importance of CT in such a group of patients. But for this technique, most of them would not be given adequate treatment and might be exposed to lifethreatening situations. (author)

    In stroke patients, collateral flow can rapidly be assessed on computed tomography angiography (CTA). In this study, the impact of baseline collaterals on early outcome and risk of symptomatic intracerebral hemorrhages after systemic thrombolysis in patients with proximal arterial occlusions within the anterior circulation were analyzed. Collateralization scores were determined on the CT angiography source images (0 = absent; 1 ≤ 50%, 2 > 50% but collateral filling) of patients with distal intracranial carotid artery and/or M1 segment occlusions treated from 2008 to December 2011. A collateral score of 0 to 1 was designated as poor and 2 to 3 as good collateral vessel status. Outcome variables included in hospital mortality, favorable outcome at discharge (modified Rankin score ≤ 2), and rates of symptomatic intracerebral hemorrhage based on the European-Australasian Acute Stroke Study II definition. Among 246 subjects (mean age of 74 years; median National Institutes of Health Stroke Scale N at admission 14), 205 patients (83%) had good collaterals, whereas 41 patients (17%) had poor collaterals, respectively. Patients with poor collaterals had significantly higher rates of in-hospital mortality (41% vs. 12%, P collaterals. The grade of collateralization was independently associated with in-hospital mortality (P collaterals have a poor early functional outcome and high rates of symptomatic intracerebral hemorrhage after systemic thrombolysis. Since similar findings have also been reported after endovascular therapy, strategies to improve collateral blood flow should be assessed in this patient population. © 2012 The Authors.

    We report on a patient who developed massive gastrointestinal hemorrhage related to the use of fluoxetine in combination with aspirin and clopidogrel. A 58-year-old man was admitted with a posterior circulation infarct with significant weakness in all four limbs and dysarthria. Aspirin and clopidogrel were started. Fluoxetine was started for pharmacological neurostimulation to promote motor recovery and for low mood. He developed gastrointestinal hemorrhage a week after fluoxetine was started. Fluoxetine was suspended and investigations failed to reveal the source of the bleeding. He was then restarted on fluoxetine along with dual antiplatelets, and gastrointestinal hemorrhage recurred after 1 week. He was extensively investigated for a source of gastrointestinal hemorrhage, and again no source could be identified. Eventually, fluoxetine was switched to mirtazapine with no further gastrointestinal hemorrhage. He remained on dual antiplatelets. A number of case-control and cohort studies had identified the association of gastrointestinal hemorrhage with the use of selective serotonin reuptake inhibitor (SSRI). We hope to raise awareness of this association in physical medicine and rehabilitation physicians as the use of SSRI is expected to rise.

    The literature is controversial on whether intraventricular bleeding has a negative impact on the prognosis of spontaneous intracerebral hemorrhage. Nevertheless, an association between intraventricular bleeding and spontaneous intracerebral hemorrhage volumes has been consistently reported. To evaluate the prognostic value of intraventricular bleeding in deep intraparenchymal hypertensive spontaneous hemorrhage with a bleeding volume bleeding was calculated by the LeRoux scale. Clinical data, including neurological complications, were collected daily during hospitalization. Neurological outcome was evaluated 30 days after the event by using the Glasgow outcome scale. Patients were assigned to 1 of 3 groups according to intraventricular bleeding: Control, no intraventricular bleeding; LR 1, intraventricular bleeding with LeRoux scale scores of 1 to 8; or LR 2, intraventricular bleeding with LeRoux scale scores >8. There were no significant differences among groups concerning age, mean blood pressure, and time from onset to brain CT scan. Patients with greater intraventricular bleeding presented lower initial Glasgow coma scale scores, increased ventricular index and width of temporal horns, increased number of clinical and neurological complications, and longer hospitalization. Furthermore, their relative risk for unfavorable clinical outcome was 1.9 (95% confidence interval 1.25-2.49). Intraventricular bleeding with a LeRoux scale score >8 appears to have a negative effect on deep spontaneous intraparenchymal cerebral hemorrhage of small volume.

Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages.
