    We report on a patient with an unusual, slowly enlarging hematoma of the left buttock. A 62-year-old man presented with a 6-year history of an enlarging mass of the left buttock. He had first noted the mass 6 years earlier and had had sciatica of the left lower limb for the last 2 months. He denied any history of antecedent trauma. The lesion extended over 3 gluteal muscles (the gluteus medius, gluteus minimus, and piriformis). On microscopic examination, the lesion showed typical signs of chronic expanding hematoma. The sciatica was relieved after surgical removal of the lesion. The lesion had not recurred at the last follow-up 4 years after the operation. The present case suggested that chronic expanding hematoma can extend into multiple muscles due, perhaps, to long-term growth and the anatomical and functional conditions of the affected muscles. Our case also suggests that chronic expanding hematoma can be a cause of piriformis syndrome.

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012....... Univariate and multivariate analyses were performed to determine the relationship between retreatment of bCSDH and clinical, radiological, and surgical variables. RESULTS Two hundred ninety-one patients with bCSDH were identified, and 264 of them underwent unilateral (136 patients) or bilateral (128 patients...

  3. Mozart's chronic subdural hematoma.

    No commemoration of the bicentennial of Mozart's death would be complete without some consideration of that premature yet predictable demise. Mozart's premonitions of death are well known and apparently played a role in the composition of the K.626 Requiem and perhaps other works. His death has traditionally been ascribed to infectious causes, chiefly rheumatic fever or post-streptococcal glomerulonephritis, exacerbated by intemperance and chronic penury. Pathology has been difficult because of his supposed burial in a pauper's grave, the location and contents of which were later supposedly lost. Mozart's burial place in St. Mark's Cemetery in Vienna was known and, in the parlance of the day, "reorganized" a decade later, as the occupants of plots were disinterred to make room for the more recently decreased. A skull believed to the Mozart's was saved by the successor of the gravedigger who had supervised Mozart's burial, and then passed into the collections of the anatomist Josef Hyrtl, the municipality of Salzburg, and the Mozarteum museum (Salzburg). Forensic reconstruction of soft tissues related to this skull reveals substantial concordance with Mozart's portraits. The skull suggests premature closure of the metopic suture, which has been suggested on the basis of his physiognomy. A left temporal fracture and concomitant erosions raise the question of chronic subdural hematoma, which would be consistent with several falls in 1789 and 1790 and could have caused the weakness, headaches, and fainting he experienced in 1790 and 1791. Aggressive bloodletting to treat suspected rheumatic fever could have decompensated such a lesion to produce his death on December 5, 1791.

    Objective: To sum up the causes of recurrence of chronic subdural hematoma (CSDH) from failure of trepanation and drainage and explore its prevention and treatment.Methods: From October 1988 to June 2002 a total of 358 patients with CSDH were treated with trepanation and drainage in our hospital. Among them 15 patients had recurrence of CSDH after operation. The data of the 15 patients were reviewed retrospectively.Results: Of the 15 patients, 13 were cured by retrepanation and redrainage, one cured by removal of hematoma by craniotomy with bone flap, and one, a 1-year old child, gave up reoperation due to severe encephalatrophy. Conclusions: Most CSDHs which recur after trepanation and drainage can be cured by retrepanation and redrainage. For the patients with repeated recurrence of CSDH removal of hematoma capsule can be considered. The causes of recurrence of CSDH are related to disease course, the thickness of hematoma capsule, the severity of encephalatraphy and whether the hematoma cavity is drained or irrigated completely, and operation methods.

    @@ Chronic subdural hematoma (CSDH) represents one of the most frequent types of intracranial hemorrhage. Management of the patients with CSDH has been evolved through a vast variety of methods and techniques. Although there is general agreement that surgical therapy is usually the preferred treatment, there are few other neurosurgical conditions that spark such strong discussions and differences of opinion concerning the optimal surgical technique.1,2 In this paper, we review advances in surgical treatment of CSDH.

    An uncommon case of chronic nontraumatic spinal epidural hematoma of the lumbar spine in a 75-year-old woman is reported. The patient presented with a 7-month history of low back pain and bilateral sciatica. Magnetic resonance imaging enabled a correct preoperative diagnosis revealing a nodular, well-circumscribed epidural mass with peripheral enhancement and signal intensities consistent with chronic hematoma, which extended from L2 to L3. Laminectomy of L2-L3 was performed and the hematoma was totally resected. Histological examination of the surgical specimen demonstrated a chronic encapsulated hematoma. No evidence of vascular malformation was found. The patient recovered fully after surgical treatment. (orig.)

    Material and Methods: Consecutive patients operated with a diagnosis of chronic subdural hematoma between January 2003 and December 2012 were reviewed retrospectively. Etiology and medical status of the patients at the time of admission were noted. Exact localization of the chronic subdural hematoma was detected by computed tomography scans and follow-up was maintained with magnetic resonance imaging. The outcome of the patients was evaluated one month after injury, by assesing activities of daily living. Results: Ninety-four consecutive patients met the eligibility criteria for the study. The mean age was 65 (range 45 to 85 years. In 74 (78.7% patients, head injury was the supposed origin. In 20 (21.3% patients, no trauma was evident. Most common symptom reported at the time of admission was headache (100%, and the most common neurological finding was confusion (87.2%. The majority of the patients had a mild neurological deficit with a Glascow Coma Scale score over eight. In general, 90.4% of cases were sufficiently treated by a single operation, while 9.6% needed a second procedure. During the follow-up, 91.5% of the patients returned to daily living activities on the first month kontrol. Conclusion: Surgical treatment of chronic subdural haematoma can give a high rate of complete recovery to normal life. [Cukurova Med J 2015; 40(1.000: 22-27

    1994-04-01

    A 9-year-old boy had been diagnosed at the age of 9 months as having a cerebellar medulloblastoma and had received 40 Gy of radiation therapy to the brain after removal of the tumor. Cerebral angiography at the time of initial diagnosis did not show any evidence of occlusive disease involving the internal carotid circulation. At the age of 6 years, the patient developed generalized seizures. On examination, he was drowsy and had right hemiparesis. CT scan demonstrated a low-density area in the left frontal lobe. Cerebral angiography showed a marked narrowing of the bilateral internal carotid arteries with moyamoya vessels. The patient was treated medically with aspirin (100 mg/day) and anticonvulsants. His neurological deficits improved gradually. At the age of 8 years, there was no recurrence of the tumor although a slight left subdural hematoma was seen on CT scan. On August 10, 1993, at the age of 9 years, he was admitted for treatment of a developing subdural hematoma. MRI showed a chronic subdural hematoma with thick outer and inner membranes. Cerebral angiography showed occlusion of the left internal carotid artery which fed the right frontal lobe through moyamoya vessels, marked narrowing of the right internal carotid artery distal to the ophthalmic artery, moyamoya vessels at the base, and cortical revascularization througth the ophthalmic, posterior cerebral and middle meningeal arteries. Trepanation and aspiration of the hematoma were performed. The outer membrane of the hematoma was about 2 mm thick and the hematoma cavity was filled with a partially organized hematoma. In this case, we speculate that development of the chronic subdural hematoma involved the following factors: (1) transdural external-internal carotid anastomosis after radiation-induced cerebrovasculopathy; (2) repeated mild head trauma due to gait disturbance after removal of the cerebellar tumor; and (3) administration of acetylsalicylic acid.

    A 72-year-old female presented with a unique case of acoustic neurinoma with a cystic component followed by the chronic subdural hematoma manifesting as trigeminal neuralgia, facial palsy and trunchal ataxia 7 months after gamma knife radiosurgery. Magnetic resonance imaging demonstrated a loss of central contrast enhancement at the postoperative residual tumor mass and a large cyst associated with a hematoma in the subdural space. A right suboccipital craniectomy was performed. A biopsy of the mass and the membrane was performed following aspiration of the brown-reddish fluid collection. The histological diagnosis was acoustic neurinoma with a hemorrhagic necrosis. The membranous tissue mimicked an outer membrane obtained from chronic subdural hematoma. The postoperative course was satisfactory and preoperative symptom have been alleviated. In this case, the chronic subdural hematoma occurred at posterior fossa during the development of cysts caused by the radiosurgery, because the subdural space had been connected with the subarachnoid space after the first operation. The development of cysts or hematoma should be taken into consideration as possible complications following treatment with gamma knife radiosurgery for acoustic neurinomas. (author)

    A 69-year-old man developed motor aphasia and right hemiparesis with severe headache, during the treatment of cellulitis and sepsis due to cat bites. Brain CT showed a low density, crescent-shaped lesion in the left subdural space, which was hypointense on brain diffusion-weighted imaging (DWI). One week later, when his neurological symptoms had worsened, the signal of the subdural lesion had changed to hyperintense on DWI. The lesion was capsule-shaped when enhanced by Gadolinium. The signal changes on DWI of the lesion indicated the existing hematoma had changed to an empyema, or so-called infected subdural hematoma, due to a hematogenous bacterial infection. Pasteurella multocida, a resident microbe in the oral cavity of cats, could be the responsible pathogen in this case. The patient recovered completely after treatment with intravenous high dose antibiotics. This is an important case report describing the transformation from a chronic subdural hematoma into a subdural empyema by DWI.

    Full Text Available 【Abstract】Objective: The surgical management of chronic subdural hematoma (CSDH is still a controver- sial issue, and a standard therapy has not been established because of the unclear pathogenic mechanisms in CSDH. The intention of this paper is to find a simple and efficient surgical procedure for CSDH. Methods: A retrospective study of 448 patients with CSDH by surgical treatment during 2005 to 2009 was con- ducted in order to compare the efficiency between two dif- ferent primary surgical methods, i.e. twist-drill drainage with- out irrigation in Group A (n=178 and one burr-hole with irrigation in Group B (n=270. The results were statistically analyzed. Results: The reoperation rates in Group A and Group B were 7.9% and 11.9% respectively. The good outcome rate was 88.8% and 75.5%, the complication was 7.9% and 20.7% in Group A and Group B, respectively. Conclusions: The burr-hole drainage with irrigation of the hematoma cavity is not beneficial to the outcome and prognosis. Irrigation is not important in the surgical treat- ment for CSDH. Thus in initial treatment, twist-drill drainage without irrigation of the hematoma cavity is recommended because it is relatively safe, time-saving and cost-effective.

    Non-traumatic intracranial acute epidural hematoma(EDH)is rare. It is mostly caused by coagulation disorders, dural metastasis, or vascular malformations of the dura. We report a case of non-traumatic acute EDH caused by chronic nasal sinusitis and review the literature comprising 10 cases of acute EDH caused by chronic nasal sinusitis. A 16-year-old boy visited our outpatient clinic with a 2-day history of severe headache. He did not have fever or neurological abnormalities and showed no evidence of head trauma. Cranial computed tomography(CT)revealed sphenoid sinusitis and a small amount of epidural air in the middle fossa, but no other intracranial abnormalities. After eight days with no subsequent history of trauma, radiological exams showed a massive acute epidural hematoma in the left middle fossa and temporal convexity without any vascular lesion or skull fracture. The patient underwent a hematoma evacuation that revealed neither a skull fracture nor a vascular abnormality. In this adolescent, chronic nasal sinusitis caused fragility of the meningeal artery wall, an air collection in the epidural space, and the detachment of the dura mater from the inner surface of the skull, thereby resulting in a non-traumatic acute EDH.

    The goal of this work is to describe the radiological appearance and clinical presentation of subperiosteal iliac hematoma and present a review of the literature. We retrospectively reviewed the radiological and clinical files of 19 patients (age range: 12-75; mean: 47) who presented with acute or chronic subperiosteal iliac hematomas. Imaging findings and relevant clinical information were recorded. A thorough literature search was performed to find additional cases of this rare condition. Three young patients presented with acute subperiosteal iliac hematoma following a fall. Clinical presentation was characterized by pain and gait disturbance presumed to result from crural nerve compression. Unilateral or bilateral lenticular hematomas deep in the iliacus muscle were demonstrated by CT for all patients while MRI was also available for two of them. In 16 asymptomatic patients, chronic ossified subperiosteal iliac hematomas were incidentally detected by CT. Progressive ossification of acute hematoma was demonstrated at follow-up in two patients. Subperiosteal iliac hematoma is rare but has typical imaging findings that may present acutely in adolescents or chronically in asymptomatic adults. (orig.)

    A 40-year-old female, who had taken low-dose oral contraceptives for 2 months before onset, developed transient dysarthria, left hemiparesis, and left hemihypesthesia. One month later, a computed tomography (CT) scan revealed a uniformly enhanced, convex-shaped, hypertrophic membrane with a lobulated lumen in the subdural space of the right parietal region. A right parietal craniotomy was performed. The membrane, consisting of elastic-hard, hypertrophic granulation tissue and yellowish, sticky fluid in the lumen, was readily freed and totally extirpated. Subsequently, the patient recovered without persistent symptoms. Light microscopic examination detected the sinusoidal channel layer and the fibrous layer in an alternating configuration, along with intramembranous hemorrhagic foci. Such hypertrophy must have been caused by repeated intramembranous hemorrhages and reactive granulation. Such findings of hematoma membrane have never previously been reported. Thus, this is an interesting case, clearly distinguished from typical chronic subdural hematoma.

    Full Text Available OBJECTIVES: The onset of chronic subdural hematoma may be associated with direct or indirect minor injuries to the head or a poorly repaired vascular injury. Endothelial progenitor cells happen to be one of the key factors involved in hemostasis and vascular repair. This study was designed to observe the levels of endothelial progenitor cells, white blood cells, platelets, and other indicators in the peripheral blood of patients diagnosed with chronic subdural hematoma to determine the possible relationship between the endothelial progenitor cells and the occurrence, development, and outcomes of chronic subdural hematoma. METHOD: We enrolled 30 patients with diagnosed chronic subdural hematoma by computer tomography scanning and operating procedure at Tianjin Medical University General Hospital from July 2009 to July 2011. Meanwhile, we collected 30 cases of peripheral blood samples from healthy volunteers over the age of 50. Approximately 2 ml of blood was taken from veins of the elbow to test the peripheral blood routine and coagulation function. The content of endothelial progenitor cells in peripheral blood mononuclear cells was determined by flow cytometry. RESULTS: The level of endothelial progenitor cells in peripheral blood was significantly lower in preoperational patients with chronic subdural hematomas than in controls. There were no significant differences between the two groups regarding the blood routine and coagulation function. However, the levels of circulating endothelial progenitor cells were significantly different between the recurrent group and the non-recurrent group. CONCLUSIONS: The level of circulating endothelial progenitor cells in chronic subdural hematoma patients was significantly lower than the level in healthy controls. Meanwhile, the level of endothelial progenitor cells in recurrent patients was significantly lower than the level in patients without recurrence. Endothelial progenitor cells may be related to the

    Chronic subdural hematoma (CSDH) is an inflammatory and angiogenic disease. Vascular endothelial growth factor (VEGF) has an important effect on the pathological progression of CSDH. The matrix metalloproteinases (MMPs) and VEGF also play a significant role in pathological angiogenesis. Our research was to investigate the level of MMPs and VEGF in serum and hematoma fluid. Magnetic Resonance Imaging (MRI) shows the characteristics of different stages of CSDH. We also analyzed the relationship between the level of VEGF in subdural hematoma fluid and the appearances of the patients' MRI. We performed a study comparing serum and hematoma fluid in 37 consecutive patients with primary CSDHs using enzyme-linked immunosorbent assay (ELISA). MMP-2 and MMP-9 activity was assayed by the gelatin zymography method. The patients were divided into five groups according to the appearance of the hematomas on MRI: group 1 (T1-weighted low, T2-weighted low, n=4), group 2 (T1-weighted high, T2-weighted low, n=11), group 3 (T1-weighted mixed, T2-weighted mixed, n=9), group 4 (T1-weighted high, T2-weighted high, n=5), and group 5 (T1-weighted low, T2-weighted high, n=8). Neurological status was assessed by Markwalder score on admission and at follow-up. The mean age, sex, and Markwalder score were not significantly different among groups. The mean concentration of VEGF, MMP-2, and MMP-9 were significantly higher in hematoma fluid than in serum (pMMP-2 was higher in hematoma fluid (pMMP-2 and MMP-9 are significantly elevated in hematoma fluid, suggesting that the MMPs/VEGF system may be involved in the angiogenesis of CSDH. We also demonstrate a significant correlation between the concentrations of VEGF and MRI appearance. This finding supports the hypothesis that high VEGF concentration in the hematoma fluid is of major pathophysiological importance in the generation and steady increase of the hematoma volume, as well as the determination of MRI appearance.

    Full Text Available CASE REPORT An 86 year-old woman experienced chest pain, dyspnea, and dysphagia two days following orthopaedic surgery for a bimalleolus fracture of the right ankle. The patient was on prophylactic low weight molecular heparin and was affected by chronic renal failure. The chest computed tomography (CT ruled out a pulmonary embolism but showed an intramural esophageal mass involving the entire esophagus. The lesion exhibited a blood like CT attenuation content that did not enhance after contrast administration. The esophagogram with gastrografin did not reveal filling defects nor communications between lumen and mucosa. Magnetic resonance confirmed CT results and excluded an aortic dissection. All radiological findings were suggestive of intramural hematoma of the esophagus. DISCUSSION AND CONCLUSIONS Intramural hematoma of the esophagus (IHE is part of the spectrum of esophageal injuries that includes Mallory-Weiss tear and Boerhaave’s syndrome. IHE is the result of a hemorrhage within the submucosal layer. Predisposing conditions are abnormal hemostasis, traumatic events, aortic diseases. It can also occur spontaneously (idiopathic. Treatment should be conservative and includes risk factors withdrawal. The hematoma usually resolves in 1 to 3 weeks.

    Full Text Available Hematological abnormalities including thrombocytopenia are common in patients living with HIV infection. Patients with HIV infection related thrombocytopenia present generally with only minor bleeding problems. But cases of subdural hematoma are very rare. A 61-year-old female with a history of HIV infection of 9 years’ duration presented with a 3-month history of generalized headache associated with visual blurring and anterograde amnesia. There was no history of trauma or fever. She was treated empirically for cerebral toxoplasmosis for 6 weeks without any improvement of the symptoms. One week prior to admission, she developed weakness of the left side of the body. Clinical examination revealed left-sided hemiparesis. Computed tomography scan of the brain showed a 25 mm chronic right frontoparietotemporal subdural hematoma compressing the lateral ventricle with midline shift. There was no appreciable cerebral atrophy. A complete blood count showed leucopenia and thrombocytopenia at 92,000 cells/mm3. Her CD4-positive cell count was 48 cells/mm3 despite receiving combination antiretroviral therapy for 9 years. A complete blood count analysis suggestive of thrombocytopenia should raise suspicion of possibilities of noninfectious focal brain lesions like subdural hematoma amongst HIV infected patients presenting with nonspecific neurological symptoms. This will enable prompt diagnosis and allow early appropriate intervention.

    Full Text Available Chronic subdural hematoma (CSDH formation mechanism is very complex, and has not entirely understood. It represents a frequent type of intracranial hemorrhage, and is very common disease in Neurosurgery practice, especially in older patients. Various surgical treatments have been proposed for the treatment of CSDH. The rate of recurrence in CSDH after surgery ranges from 5% to 30%, repeated surgery must be considered. But in some cases subdural collections are still persistent. Endovascular embolization of the middle meningeal artery (MMA is an option for treatment of refractory CSDH. We review all cases that were treated with embolization to assess the effect of this intervention. Our review revealed 6 papers with a total enrollment of 14 patients were treated with MMA embolization for refractory chronic subdural hematoma without any postoperative complication or recurrence. In this study we suggest MMA embolization as an alternative for treatment of non-curable CSDH, especially for old people with systematic diseases, who cannot tolerate repeat surgery.

    Objective  To describe a surgical technique and to report using a retrospective study the efficacy of peritoneal shunts for the treatment of recurrent/chronic subdural hematoma (CSDH). We describe the considerations, complications, and outcomes related to this technique. Methods  In a retrospective cohort study, 125 charts with a diagnosis of subacute/chronic subdural hematoma were assigned for evaluation. Of the charts reviewed, 18 charts were found from subjects with a diagnosis of recurrent sub-acute or chronic subdural hematoma. All patients had undergone initial surgical treatment of their condition followed by peritoneal shunt placement to help alleviate intracranial pressure. Factors including the age, size of subdural hematoma, number of previous events, BMI, complications, survival, and clinical course were analyzed. Results  After subdural peritoneal shunt placement all patients had full neurological recovery with no complaints of headaches, lethargy, weakness, confusion or seizures. None of the cases had new subdural hematoma episodes after placement for a minimum of a two-year period (mean 26.1 months) (range 24.3-48.6 months). No postoperative complications were reported. The rates of postoperative hemorrhage, infection, distal catheter revision, and perioperative seizures was found to be zero percent. Shunt drainage was successful in all cases, draining 85% of the blood in the first 48 hours. There was no significant relationship between complications and the use of anticoagulants four weeks after surgery. Conclusions Peritoneal shunts, though rarely used, are a viable option in the treatment of sub-acute/chronic subdural hematomas. When pursuing this treatment, this technique is recommended to mitigate the risks of repeat surgical intervention and lessen perioperative time in high-risk patients. PMID:27335718

    Full Text Available The clinical manifestation of chronic subdural hematoma is not limited to neurological deficits or cognitive impairment. It may present with behavioral abnormalities. When the behavioral abnormalities present without obvious neurological deficits and in the absence of trauma, it leads to misdiagnosis. A trivial trauma may cause intracranial bleed that is either missed or ignored in the clinical history. This case report highlights the clinical picture of a homeless patient who presented with withdrawn and disorganized behavior, apathy and poverty of speech in the absence of any neurological deficit. His clinical presentation led to a possibility of psychosis and he was started on antipsychotics. He had developed extrapyramidal side effects in low dose of antipsychotic without any clinical benefit in his clinical picture. Neuroimaging done to rule out any possible organicity-revealed bilateral subdural hematoma, which was later evacuated by neurosurgical intervention in multiple settings and the patient had improved. This case report unfolds the mystery behind the psychotic presentation in a homeless adult.

    OBJECTIVE: Recurrence rates of between 5% and 25% have been reported following surgery for chronic subdural hematoma (CSH). A previous study showed that the treatment with angiotensin converting enzyme (ACE) inhibitors decreases the risk of recurrence. To test the effects of ACE inhibitors...... perindopril 5mg or placebo treatment daily for three months prior to surgery. Cerebral CT scans were performed after six weeks, and clinical follow-ups were performed three months after surgery. Additionally, a retrospective analysis of the data and CT scans from all nonrandomized patients from the same time...... surgery revealed no difference between the placebo and perindopril-treated groups. In the retrospective group (245 patients), there was no correlation between the risk of recurrence and ACE inhibitor treatment. CONCLUSION: Our data suggest that perindopril does not diminish the size of residual CSHs six...

    Full Text Available BACKGROUND: The treatment of chronic subdural hematoma (cSDH is still charged of significant risk of hematoma recurrence. Patient-related predictors and the surgical procedures themselves have been addressed in many studies. In contrast, postoperative management has infrequently been subjected to detailed analysis. Moreover variable intravenous fluid administration (IFA was not reported in literature till now in the context of cSDH treatment. METHODOLOGY/PRINCIPAL FINDINGS: A total of 45 patients with cSDH were operated in our department via two burr hole craniostomy within one calendar year. Downward drainage was routinely left in hematoma cavity for a one day. Independent variables selected for the analysis were related to various aspects of patient management, including IFA. Two dependent variables were chosen as measure of clinical course: the rate of hematoma recurrence (RHR and neurological status at discharge from hospital expressed in points of Glasgow Outcome Scale (GOS. Univariate and multivariate regression analyses were performed. Hematoma recurrence with subsequent evacuation occurred in 7 (15% patients. Univariate regression analysis revealed that length of IFA after surgery influenced both dependent variables: RHR (p = 0.045 and GOS (p = 0.023. Multivariate regression performed by backward elimination method confirmed that IFA is a sole independent factor influencing RHR. Post hoc dichotomous division of patients revealed that those receiving at least 2000 ml/day over 3 day period revealed lower RHR than the group with less intensive IFA. (p = 0.031. CONCLUSIONS/SIGNIFICANCE: IFA has been found to be a sole factor influencing both: RHR and GOS. Based on those results we may recommend administration of at least 2000 ml per 3 days post-operatively to decrease the risk of hematoma recurrence.

    Nontraumatic spinal epidural hematoma (SEH) is a rare condition and the exact cause of the hemorrhage in SEH had never been established. However, there have been a few recent reports on some types of the epidural hematoma with a detectable origin of hemorrhage. We encountered a case of chronic SEH in a patient who had spondylolytic spondylolisthesis, which is also a rare condition to be associated with SEH. We report here on the radiologic findings of a case of chronic epidural hematoma in a patient who had spondylolytic spondylolisthesis at the L4-5 level, and we include a review of the related literatures.

Clinical picture is characterized by abdominal mass and anemia; diagnosis is confirmed by imagenology. Two patients with suprarrenal hematoma from the University Hospital at Cartagena, Colombia, are presented. Both were related with traumatic delivery and cephalohematoma; one of them had oral and gastric bleeding and the othersuffered hematoma infection; diagnosis was done with abdominal ecography and CAT. Both patients recovered with medical treatment. La hemorragia suprarrenal asintomática del neonato es relativamente frecuente y muchas veces se detecta como una calcificación local después de que se resuelve el hematoma. La forma sintomática es rara y, a menudo, se debe a un trauma obstétrico relacionado con la macrosomía fetal, la presentación podálica, la diabetes materna o la hipoxia perinatal. Las manifestaciones clínicas son, principalmente, una masa abdominal y anemia importante; el diagnóstico se confirma con la imaginología. Se presentan dos casos de hematoma suprarrenal derecho tratados en el Hospital Universitario de Cartagena, ambos relacionados con un parto traumático y acompañados de cefalohematomas; uno de ellos presentó sangrado gastrointestinal alto y el otro infección del hematoma suprarrenal. El diagnóstico se comprobó con la ecografía abdominal y se verificó con la tomografía. El tratamiento fue médico y no se requirió cirugía a pesar de la anemia severa que presentó uno de los pacientes.

    Compared with burr hole craniostomy (BHC), twist drill craniostomy (TDC) is increasingly popular because of its minimal invasiveness in evacuating chronic subdural hematoma (CSDH). However, the TDC technique varies and is continually developing; moreover, no consensus yet exists regarding the optimal protocol, and the efficacy and safety of TDC is still controversial, especially with respect to a specific method. This article introduces a new modified TDC technique using a novel device, the YL-1 puncture needle, and evaluates its efficacy and advantages compared with BHC.A retrospective study involving 121 patients with CSDH who underwent surgery at a single center was conducted, involving 68 patients undergoing modified TDC (TDC group) and 53 patients treated by BHC (BHC group). The neurological outcome was studied to evaluate the surgery efficacy, and the radiological outcome was assessed as a supplement to the surgery efficacy. In addition, complications, recurrence, and reoperation, as well as pneumocrania, operation duration, and length of stay, were studied to evaluate the advantages of the modified TDC compared with BHC. Independent sample t tests or rank-sum tests were used to compare the outcomes between the 2 groups.The neurological and radiological outcomes did not differ significantly between the TDC and BHC groups (P = 0.852 and P = 0.232, respectively), while the rates of complication and pneumocrania in patients who underwent the modified TDC were significantly lower than that in those who underwent BHC (P = 0.021 and P TDC were significantly shorter than those of the patients who underwent BHC (both P TDC with a YL-1 puncture needle is a minimally invasive surgical technique to treat CSDH; this procedure is as effective as BHC, but safer and simpler than BHC, and should be considered for patients with CSDH, especially the elderly.

    Traumatic CSDH enlarged in two cases with VP or LP shunt system although the shunt valve pressure was increased to 200 mmH2O. In surgery, the hematoma cavity pressure was found to be 130 and 140 mmH2O, suggesting that to raise the shunt valve pressure is not effective for decreasing CSDH volume.

    Objective: To investigate the treatment of chronic subdural hematoma (CSDH) with burr-hole craniotomy in our hospital.Methods: From January 2004 to December 2009, 398patients with CSDH, 338 males and 60 females (male/female=5.63/1 ), received burr-hole craniotomy in our hospital.The median age was 60 years with the mean age of (58. 1± 18. 1 )years, (65.0±14.5) years for females and (57.0±18.2) years for males. Trauma history was determined in 275 patients (69. 1%).Burr-hole craniotomy was performed under local anesthesia in 368 patients and general anesthesia in 30 patients.CSDH was classified into 3 groups according to the density on CT scan. Clinical data concerning etiologies, symptoms and signs, concomitant diseases, diagnosis, therapies and outcomes were investigated retrospectively. Patients' neurological status on admission and at discharge was also classified to judge the outcomes.Results: Generally, trauma history showed few differences between those over 60 years old and under 60 years old, but showed obvious differences when gender was taken into account. Totally 123 male patients (60.0% of 204 cases) suffering from head injuries were under 60 years,whereas 35 female patients (85.4% of 41 cases) with trauma histories were over 60 years. The duration from trauma to appearance of clinical symptoms was (84.0±61.7) days (range,0-1493 days). Traumatic accident was the leading etiology,other accompanying diseases such as cerebral vascular disease, hypertension, etc, were also predisposing factors.Commonly, the elderly presented with hemiplegia/hemidysesthesia/hemiataxia and the young with headache.Most CSDH patients (95.6%) treated with burr-hole craniotomy successfully recovered. However, postoperative complications occurred in 17 cases, including recurrence of CSDH in 15 cases, subdural abscess in 1 case and pneumonia in 3 cases.Conclusion: Burr-hole craniotomy is an easy, efficient and reliable way to treat CSDH.

    A 78-year-old man who had a history of myocardial and cerebral infarction and who was treated with aspirin and warfarin, presented with left chronic subdural hematoma. Cerebral computed tomography showed severe brain compression of hematoma with midline shift, indicating the need for emergent surgery. The hematology and clotting tests upon admission revealed severe thrombocytopenia (platelet count, 1.3 × 10(4)/μL) with normal clotting activity. Because platelet aggregation was evident in the smear, we re-examined the patient for hematology using tubes that contained heparin, showing also low platelet count (2.3 × 10(4)/μL). The day on admission, we performed irrigation and drainage of the chronic subdural hematoma through single burr-hole craniostomy. During surgery, we used 10 units of platelet concentrates (PCs) for the reason that the patient was taking aspirin and coagulopathy derived from low platelet count could not be excluded. After surgery, we re-evaluated the hematology of the blood stored in tubes that contained ethylenediaminetetraacetic acid (EDTA) with or without kanamycin (KM). Treatment with KM dissociated EDTA-induced platelet aggregation and revealed platelet counts with highest accuracy (no KM treatment, 1.3 × 10(4)/μL; KM treatment, 15.2 × 10(4)/μL). This phenomenon is called EDTA-Dependent Pseudothrombocytopenia (PTCP) defined as falsely low platelet counts reported by automated hematology analyzers due to platelet aggretgation. Awareness of the phenomenon will enable neurosurgeons to manage patients with PTCP appropriately and clinical laboratory especially in emergency hospital is recommended to prepare for the hematological tubes being added KM in routine analysis, resulting in preventing mistaken diagnosis.

    Full Text Available Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, occurring mostly during anticoagulation therapy. The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma.Hematomas subdurais da fossa posterior são lesões raras, mais comumente relacionadas com traumas graves.

    The development of a large hematoma impairing visualization of the distal true lumen is a recognized complication of antegrade recanalization of chronic total occlusions, often forcing the operator to abort the procedure or switch to a retrograde approach. We describe a novel technique utilizing an over-the-wire balloon inflated in the proximal occluded vessel to block inflow and allow aspiration of the blood from the subintimal space. This decompressed the true lumen, restored distal visualization, and allowed successful reentry using a dedicated technology. Utilization of this novel technique may rescue antegrade recanalization attempts complicated by large subintimal hematomas.

    There is controversy among neurosurgeons regarding whether irrigation or drainage is necessary for achieving a lower revision rate for the treatment of chronic subdural hematoma (CSDH) using burr-hole craniostomy (BHC). Therefore, we performed a meta-analysis of all available published reports. Multiple electronic health databases were searched to identify all studies published between 1989 and June 2012 that compared irrigation and drainage. Data were processed by using Review Manager 5.1.6. Effect sizes are expressed as pooled odds ratio (OR) estimates. Due to heterogeneity between studies, we used the random effect of the inverse variance weighted method to perform the meta-analysis. Thirteen published reports were selected for this meta-analysis. The comprehensive results indicated that there were no statistically significant differences in mortality or complication rates between drainage and no drainage (P > 0.05). Additionally, there were no differences in recurrence between irrigation and no irrigation (P > 0.05). However, the difference between drainage and no drainage in recurrence rate reached statistical significance (P meta-analysis suggest that burr-hole surgery with closed-system drainage can reduce the recurrence of CSDH; however, irrigation is not necessary for every patient.

    Full Text Available Chronic subdural hematoma (CSDH is common squeal of trauma and rarely associated with anticoagulant therapy, antiplatelet, chemotherapeutic drugs, arteriovenous malformation, aneurysms and post-craniotomy. However its occurrence is very unusual with systemic haematological malignancy and mostly reported with acute myeloid leukemia; however incidence of SDH occurrence in chronic myelogenous leukemia (CML is very rare. CML is a haematological malignancy characterized by chromosomal alteration, pathologically represents increased proliferation of the granulocytic cell line without loss of capacity to differentiate. CML has three phases - remission phase, accelerated phase and blast crisis. About 85 % of patients present in remission phase of disease and carries a favorable prognosis. As intracranial, subdural hematoma usually occur in the accelerated phase or blast crisis phase or extremely uncommon during chronic remission phase, although only those affected, who are neglecting therapeutic medication or discontinued therapy or rarely as an adverse effect of medications. However, important role of neurosurgeon lies in early detection and correction of platelet count and associated hematological abnormality as quite sizeable proportion of cases may not need surgical intervention instead can be managed conservatively under regular supervision in association with oncologist colleague, but few cases may need urgent surgical intervention. So, selecting a subgroup of CML cases in the remission phase requiring surgical intervention, presenting with CSDH is not only challenging, as failure to make an informed and timely precise decision can lead to catastrophic worse outcome and even mortality. So, purpose of current article is to formulate the management therapeutic plan. Authors report three cases of CML in chronic remission phase, receiving treatment under guidance of Haemto-oncologist at our institute presented with spontaneous chronic SDH. The mean

Methods From February 2005 to February 2008, the clinical data of 20 elderly pa-tients suffered from chronic subdural hematoma were analyzed retrospectively. The patients were all treated by mini-mally invasive operations, along with the supportive treatment for repnsition of the brain. Results The hematomas (mean volume, 100 ml) were all cleared away postoperation. Brain reposition was obtained 24 hours ~ 7 days(mean, 3 days) after operations. All patients were cured to discharge. 20 patients were followed up for 3 ~ 12 months (mean,7 months). According to the activities of daily living (ADL) grading system, 16 patients were classified as normal, and 4 independent. Follow-up examination with CT scans in 16 patients showed 13 cases of normal findings, 2 cases of brain atrophy, and 1 mild subdural effusion. Conclusion Minimally invasive evacuation of hematoma is suited to elderly patients with chronic subdural hematoma,providing a satisfactory effect and a low recurrence rate.

    Full Text Available BACKGROUND AND PURPOSE: In the last decade there has been an increasing use of antiplatelet/anticoagulant agents in the elderly. The aim of the study was to evaluate the association between exposure to anticoagulant/antiplatelet therapy and chronic subdural haematoma-CSDH. METHODS: Single institution case-control study involving 138786 patients older than 60 years who visited our academic tertiary care Emergency Department from January 1st 2001 to December 31st 2010. 345 patients with CSDH (cases were identified by review of ICD-9 codes 432.1 and 852.2x. Case and controls were matched with a 1:3 ratio for gender, age (± 5 years, year of admission and recent trauma. A conditional logistic model was built. A stratified analysis was performed with respect to the presence (842 patients or absence (536 patients of recent trauma. RESULTS: There were 345 cases and 1035 controls. Both anticoagulant and antiplatelet agents were associated with an increased risk of CSDH with an OR of 2.46 (CI 95% 1.66-3.64 and 1.42 (CI 95% 1.07-1.89, respectively. OR was 2.70 (CI 95% 1.75-4.15, 1.90 (CI 95% 1.13-3.20, and 1.37(CI 95% 0.99-1.90 for patients receiving oral anticoagulants, ADP-antagonists, or Cox-inhibitors, respectively. History of recent trauma was an effect modifier of the association between anticoagulants and CSDH, with an OR 1.71 (CI 95% 0.99-2.96 for patients with history of trauma and 4.30 (CI 95% 2.23-8.32 for patients without history of trauma. CONCLUSIONS: Anticoagulant and antiplatelet therapy have a significant association with an increased risk of CSDH. This association, for patients under anticoagulant therapy, appears even stronger in those patients who develop a CSDH in the absence of a recent trauma.

    The Chronic Care Model (CCM) developed by is an influential and accepted guide for the care of patients with chronic disease. Wagner acknowledges a current healthcare focus on acute care needs that often circumvents chronic care coordination. He identifies the need for a "division of labor" to assist the primary care physician with this neglected function. This article posits that the role of chronic care coordination assistance and disease management fits within the purview of home healthcare and should be central to home health chronic care delivery. An expanded Home-Based Chronic Care Model (HBCCM) is described that builds on Wagner's model and integrates salient theories from fields beyond medicine. The expanded model maximizes the potential for disease self-management success and is intended to provide a foundation for home health's integral role in chronic disease management.

A variety of treatment options like subdural tapping, endoscopic washout, shunting and craniotomy have been discussed. In chronic subdural hematoma, spontaneous resolution with conservative treatment is not an common therapeutic method because it has causes high mortality, requires long periods of time, and finally, many patients need surgical treatment.

The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

    Postoperative extradural hematoma (POEH) is a possible complication after head surgery, often neglected in the literature. In a single surgeon experience we found 13 cases of POEH (0.8%). We distinguished two subtypes: (1) larger hematomas (>40 cc) with typical features and overt clinical picture that always needed evacuation, and (2) smaller hematomas (<40 cc) with insidious clinical onset and different radiological features compared with traumatic and spontaneous extradural hematomas. On the basis of our experience, we propose that clinical picture and radiologic appearance lead the decision between conservative or interventional treatment of type II hematomas.

    Metrizamide CT cisternograms (CTC) were performed in order to examine the CSF passage to subarachnoid space, cerebral sulci and Sylvian fissure. The old aged 20 patients (from 63 to 88 years old) with the layer of low density area around bilateral frontal lobe (bi-frontal LDA) in plain CT finding were selected from 2000 aged patients hospitalized in Hanwa-Senboku Hospital. In these 20 patients, it was difficult to differentiate frontal lobe atrophy from the chronic subdural hematoma and subdural hygroma. Conservative therapy was applied in 19 patients for their old age or their complicated diseases. Only 1 patient was operated for subdural hygroma. The 20 patients were investigated in EEGs, severity of dementia, disturbance of consciousness, activity of daily life, their clinical course and prognosis. Only 2 of the 11 patients with type 1 CTC findings (cerebral sulci, Sylvian fissure and bi-frontal LDA were simultaneously enhanced by metrizamide) showed disturbance of consciousness and/or delirium for their serious somatic disorders. All of 6 patients with type 3 CTC findings (only bi-frontal LDA was not enhanced by metrizamide) showed disturbance of consciousness. Three patients with type 2 CTC findings (atypical findings) were reported independently. Subdural disorder elevating intracranial pressure were clarified in the cases with type 3 CTC findings.

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

    Objective To explore the risk factors related to recurrent chronic subdural hematoma (CSDH). Methods 171 cases with CSDH were retrospectively analyzed. Results 18 cases were recurrent after surgery with a recurrent rate of 10.5%. Single factor Χ2 analysis showed that the recurrence of CSDH was related to age, hematoma density, hematoma location, midline shift, Bender classfication, encephalatrophy classfication,drainage amount, and bleeding tendency (P < 0.05), regardless of gender,anesthesia mode,and injury history (P > 0.05). Age, hematoma density, midline shift, Bender classfication,encephalatrophy classfication,and bleeding tendency were found to be independently associated with the recurrence of CSDH by Logistic multifactorial analysis (P < 0. 05). Conclusions Patient age,hematoma density, midline shift, Bender classfication, encephalatrophy classfication, and bleeding tendency are prognostic factors fpatients for with CSDH. We should pay more attention to the recurrent risk factors,and implement corresponding prevention strategies.%目的 探讨慢性硬膜下血肿(chronic subdural hematoma,CSDH)术后复发的相关因素.方法 回顾性分析171例CSDH患者的临床资料.结果 本组CSDH患者术后共有18例复发,复发率为10.5%.单因素χ<'2>检验显示CSDH术后复发与年龄、血肿密度、血肿位置、中线移位、Bender分级、脑萎缩分级、引流量和出血倾向相关(P<0.05).与性别、麻醉方式和有无外伤史无关(P>0.05).Logistic多因素分析显示年龄,血肿密度、中线移位、Bender分级、脑萎缩分级和出血倾向为CSDH患者术后复发危险因素(P<0.05).结论 CSDH患者的年龄、血肿密度、中线移位、Bender分级和出血倾向与患者的预后密切相关,应针对复发的高危因素,做好相应的防治工作.

    Full Text Available Background: Chronic subdural hematoma (CSDH is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. Materials and Methods: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008-2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. Results: From 137 patients with CSDH, 106 (77.3% were males and 31 (22.7% females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%. The head trauma has been responsible for CSDH in 88 patients (64.3%, while the main symptom was headache (92 patients or 67.1%. One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%. The recurrence of CSDH was 6.5%, whereas mortality 2.9%. Conclusion: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety.

    Full Text Available Hemorrhage into the soft tissues of the airway represents a potentially life-threatening complication of long-term anticoagulation. We report the case of a chronically anticoagulated 37-year-old male who developed a spontaneous hematoma of the epiglottis secondary to a supra-therapeutic INR. Epiglottic hematoma should be considered in the differential of any anticoagulated patient presenting with upper airway compromise. The airway should be secured in a controlled fashion, and the coagulopathy should be rapidly corrected.

    2011-01-01

    Full Text Available We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture. Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

    Full Text Available Background: Chronic subdural hematoma (CSDH is a very common clinical emergency encountered in neurosurgery. While both general anesthesia (GA and monitored anesthesia care (MAC can be used during CSDH surgery, MAC is the preferred choice among surgeons. Further, while dexmedetomidine (DEX is reportedly a safe and effective agent for many diagnostic and therapeutic procedures, there have been no trials to evaluate the safety and efficacy of DEX vs. sufentanil in CSDH surgery. Objective: To evaluate the safety and efficacy of DEX vs. sufentanil in MAC during burr-hole surgery for CSDH.Methods: In all, 215 fifteen patients underwent burr-hole surgery for CSDH with MAC and were divided into three groups: Group D1 (n=67, DEX infusion at 0.5 μg·kg–1 for 10 min, Group D2 (n=75, DEX infusion at 1 μg·kg–1 for 10 min, and Group S (n=73, sufentanil infusion 0.3 μg·kg–1 for 10 min. Ramsay sedation scale (RSS of all three groups was maintained at 3. Anesthesia onset time, total number of intraoperative patient movements, hemodynamics, total cumulative dose of DEX, time to first dose and amount of rescue midazolam or fentanyl, percentage of patients converted to alternative sedative or anesthetic therapy, postoperative recovery time, adverse events, and patient and surgeon satisfaction scores were recorded.Results: The anesthesia onset time was significantly less in group D2 (17.36±4.23 vs. 13.42±2.12 vs. 15.98±4.58 min, respectively, for D1, D2, S; P<0.001. More patients in groups D1 and S required rescue midazolam to achieve RSS=3 (74.63% vs. 42.67% vs. 71.23%, respectively, for D1, D2, S; P<0.001. However, the total dose of rescue midazolam was significantly higher in group D1 (2.8±0.3 vs. 1.9±0.3 vs. 2.0±0.4 mg, respectively, for D1, D2, S; P<0.001. The time to first dose of rescue midazolam was significantly longer in group D2 (17.32±4.47 vs. 23.56±5.36 vs. 16.55±4.91 min, respectively, for D1, D2, S; P<0.001. Significantly fewer

    The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both age-related and atypical features when compared with epidural hematoma in adults. In selected cases, prompt surgical evacuation of the hematoma results in an excellent outcome. Outcomes seem to be directly related to the patient's preoperative neurologic status and the presence of associated intracranial lesions.

    Full Text Available In part one of this 2-part series, we reviewed the important roles that laws have played in public health and provided examples of specific laws and their effectiveness in supporting public health interventions (1. We suggested that conceptual legal frameworks for systematically applying law to preventing and controlling chronic diseases have not been fully recognized and we provided the basic elements of a conceptual legal framework. In part 2 of this series, we first provide an overview of U.S. jurisprudence, describe the legal mechanisms, remedies, and tools for applying law to public health, and summarize the jurisdictional levels at which laws, mechanisms, remedies, and tools operate. We then identify the potential contours for legal frameworks of varying complexity and scope by offering examples of legal frameworks in public health practice. This paper also outlines a plan for increasing the capacity within the Centers for Disease Control and Prevention (CDC for developing legal frameworks and expanding guidance on using legal tools for preventing and controlling chronic diseases. Finally, we describe resources for building or enhancing the capacity to use law as a tool for preventing diseases, injuries, and disabilities at the local level.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptosis, and diplopia, without a history of trauma. Computer tomography demonstrated a fairly well defined extraconal lesion with opacification of the paranasal sinuses. The principal differential based on all findings was that of a spreading sinus infection and an extraconal tumor. An unprecedented finding of a spontaneous orbital hematoma was discovered when the patient was taken to theater. We discuss the rarity of this condition and its management.Keywords: hemorrhage, ophthalmology, spontaneous, intra-orbital, hematoma

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    @@INTRODUCTION Esophageal hematomas develop from the dissection of the mucosa from the muscular layers of the esophageal wall and represent an uncommon condition affecting all ages[t-3]. Although the most common cause of esophageal hematomas is iatrogenic mechanical injury-induced by prolonged nasogastric intubation, difficult or forceful endoscopic intubation, or the result of variceal injection sclerotherapy- some may be spontaneous,particularly in patients receiving anticoagulants[3-6]. Presenting symptoms most commonly include dysphagia, hematemesis, and sub-sternal or epigastric pain[5,9].

    Full Text Available Sébastien Lobet,1,2 Cedric Hermans,1 Catherine Lambert1 1Hemostasis-Thrombosis Unit, Division of Hematology, 2Division of Physical Medicine and Rehabilitation, Cliniques Universitaires Saint-Luc, Brussels, Belgium Abstract: Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed by the hematologist, managing acute hemarthrosis and chronic arthropathy requires a close collaboration between the orthopedic surgeon and physiotherapist. This collaboration, comprising a coagulation and musculoskeletal specialist, is key to effectively preventing hemarthrosis, managing acute joint bleeding episodes, assessing joint function, and actively treating chronic arthropathy. This paper reviews, from a practical point of view, the pathophysiology, clinical manifestations, and treatment of hemarthrosis and chronic hemophilia-induced arthropathy for hematologists, orthopedic surgeons, and physiotherapists.

    Objective:To investigate the clinical characteristics of intracranial hematoma and the mechanism involved in its rapid natural resolution. Methods:Seventeen cases of intracranial hematoma with typical clinical and CT manifestations were retrospectively studied. Results: Intracranial hematoma was found obviously decreased in size within 72 h after its occurrence in 8 cases. The rest 9 cases presented complete resolution. Conclusions: Rapid natural resolution of acute epidural hematoma is mostly found in teenagers and the resolution is correlated with cranial fracture at the hematoma site. As for acute subdural hematoma, its rapid resolution is associated with the transfer of cerebrospinal fluid toward subdural space, the lavage effect, and the compression caused by the increased intracranial pressure or the space left resulting from redistribution of the hematoma in brain atrophy.

    Full Text Available The treatment of chronic back pain is a challenging problem. Facet joint infiltration is an established treatment for chronic low back pain caused by arthrosis of the lumbar facet joints. Due to the increasing number of patients with chronic low back pain, this therapy has become more frequent. We treated a 51-year-old male patient, who developed an epidural hematoma 2 months after infiltration therapy. Our case shows that even a delayed onset of spinal epidural hematoma is possible and should be kept in mind as a possible cause of acute myelopathy after spinal intervention.

  16. Is human fracture hematoma inherently angiogenic?

    LENUS (Irish Health Repository)

    Street, J

    2012-02-03

    This study attempts to explain the cellular events characterizing the changes seen in the medullary callus adjacent to the interfragmentary hematoma during the early stages of fracture healing. It also shows that human fracture hematoma contains the angiogenic cytokine vascular endothelial growth factor and has the inherent capability to induce angiogenesis and thus promote revascularization during bone repair. Patients undergoing emergency surgery for isolated bony injury were studied. Raised circulating levels of vascular endothelial growth factor were seen in all injured patients, whereas the fracture hematoma contained significantly higher levels of vascular endothelial growth factor than did plasma from these injured patients. However, incubation of endothelial cells in fracture hematoma supernatant significantly inhibited the in vitro angiogenic parameters of endothelial cell proliferation and microtubule formation. These phenomena are dependent on a local biochemical milieu that does not support cytokinesis. The hematoma potassium concentration is cytotoxic to endothelial cells and osteoblasts. Subcutaneous transplantation of the fracture hematoma into a murine wound model resulted in new blood vessel formation after hematoma resorption. This angiogenic effect is mediated by the significant concentrations of vascular endothelial growth factor found in the hematoma. This study identifies an angiogenic cytokine involved in human fracture healing and shows that fracture hematoma is inherently angiogenic. The differences between the in vitro and in vivo findings may explain the phenomenon of interfragmentary hematoma organization and resorption that precedes fracture revascularization.

    Two cases of ethmoid hematoma of the equine are reported. Clinically both horses had intermittent unilateral epistaxis unassociated with exercise. In one horse, diagnosis was based on the use of an endoscope for visualization and for biopsy of a mass associated with the ethmoid turbinates. In the other horse, exploratory trephination of the posterior maxillary sinus was necessary to obtain a diagnostic biopsy specimen. Radiography was helpful in the diagnosis of one case.

    Full Text Available Abstract Background Intraseptal hematoma and subsequent myocardial infarction due to accidental contrast agent deposition complicating diagnostic cineventriculography is a previously undescribed complication of angiography. Case presentation A 61 year old man was admitted at intensive care unit because of unstable angina pectoris 1 hour after coronary angiography. Transthoracic contrast echocardiography showed a non-perfused area in the middle of interventricular septum with an increase of thickening up to 26 mm. Review of cineventriculography revealed contrast enhancement in the interventricular septum after contrast medium injection and a dislocation of the pigtail catheter tip. Follow up by echocardiography and MRI showed, that intramural hematoma has resolved after 6 weeks. After 8 weeks successful stent implantation in LAD was performed and after 6 month the patient had a normal LV-function without ischemic signs or septal thickening demonstrated by stressechocardiography. Conclusion A safe and mobile position of the pigtail catheter during ventriculography in the middle of the LV cavity should be ensured to avoid this potentially life-threatening complication. For assessment and absolute measurement of intramural hematoma contrast-enhanced echocardiography is more feasible than MRI and makes interchangeable results.

    Full Text Available Introduction: Extradural hematomas (EDHs accounts for approximately 2% of patients following head trauma and 5-15% of patients with fatal head injuries. When indicated, the standard surgical management consists of evacuation of the hematoma via craniotomy. Intraoperative development of acute extradural hematoma (AEDH on the contralateral side following evacuation of acute extradural hematoma is uncommon and very few cases have been reported.

    Conclusion: Although hemorrhage from the thyroid gland without blunt trauma is rare, emergency physicians should regard possible thyroid gland rupture in patients with swelling of the neck or acute respiratory failure after direct/indirect trauma to the neck. Observation or operative management for limited or expanding hematoma are appropriately based on fundamental neck trauma principles.

    Hepatitis C virus (HCV) infection is an important worldwide public health problem, and most of the global HCV burden is in low- to middle-income countries. This study aimed to estimate the future burden of chronic hepatitis C (CHC) and the impact of public health policies using novel antiviral agents in Thailand. A mathematical model of CHC transmission dynamics was constructed to examine the disease burden over the next 20 years using different treatment strategies. We compared and evaluated the current treatment (PEGylated interferon and ribavirin) with new treatments using novel direct-acting antiviral agents among various treatment policies. Thailand’s CHC prevalence was estimated to decrease 1.09%–0.19% in 2015–2035. Expanding treatment coverage (i.e., a five-fold increment in treatment accessibility) was estimated to decrease cumulative deaths (33,007 deaths avoided, 25.5% reduction) from CHC-related decompensated cirrhosis and hepatocellular carcinoma (HCC). The yearly incidence of HCC-associated HCV was estimated to decrease from 2,305 to 1,877 cases yearly with expanding treatment coverage. A generalized treatment scenario (i.e., an equal proportional distribution of available treatment to individuals at all disease stages according to the number of cases at each stage) was predicted to further reduce death from HCC (9,170 deaths avoided, 11.3% reduction) and the annual incidence of HCC (i.e., a further decrease from 1,877 to 1,168 cases yearly, 37.7% reduction), but cumulative deaths were predicted to increase (by 3,626 deaths, 3.7% increase). Based on the extensive coverage scenario and the generalized treatment scenario, we estimated near-zero death from decompensated cirrhosis in 2031. In conclusion, CHC-related morbidity and mortality in Thailand are estimated to decrease dramatically over the next 20 years. Treatment coverage and allocation strategies are important factors that affect the future burden of CHC in resource-limited countries like

    Background Bleeding from bypass anastomosis leakage occurs early after coronary artery bypass grafting. Later, once the anastomosis is covered by intima, spontaneous bleeding is unlikely. Case Description A 63-year-old male patient developed a pseudoaneurysm-like, subepicardial late-term bleeding resulting in a hematoma that compromised coronary artery flow by increasing extracoronary pressure. This resulted in severe angina pectoris (Canadian Cardiovascular Society IV) and myocardial ischemia within the affected area. After surgical removal of the hematoma and repair of the anastomosis, the patient's symptoms disappeared and no signs of myocardial ischemia were present. Conclusion Surgical removal is an efficient therapy for subepicardial hematoma inducing myocardial ischemia.

    Study Design Case report. Objective To report the first case of ligamentum flavum hematoma after cervical spine instrumentation 11 years after the index surgery. Methods After performing bilateral C3 and C4 laminectomy, we observed a dark greenish discoloration over the ligamentum flavum, which was opened. We evacuated 15 mL of subacute hematoma. Results The first ligamentum flavum hematoma of the cervical spine that occurred after spinal instrumentation with sublaminar hooks. Conclusion Ligamentum flavum hematoma might happen even after a long delay (in our case, 11 years) from spinal instrumentation (sublaminar hooks). In symptomatic patients, evacuation is the treatment of choice. In cases of instrument adhesion to the surrounding intracanal tissues, removal should be done meticulously after performing a complete release.

    Full Text Available Background: Subdural hematoma (SDH is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes. Objectives: To determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma. Materials and Methods: We retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery. Results: Forty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005, yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44% were discharged home, 16 (36% discharged to nursing home or rehab, 6 (13% to hospice and 3 (7% died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed. Conclusion: Surgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.

    Spinal epidural hematoma is an accumulation of blood in the potential space between the dura and bone. On unenhanced computed tomography epidural hemorrhage appears as a high-density spinal canal mass with variable cord compression. Magnetic resonance imaging is the modality of choice for evaluating spinal epidural hematoma and can demonstrate the extent of the hematoma and degree of cord compression. When treated surgically the outcome depends on the extent of preoperative neurological deficits and on the operative timing interval. (orig.) [German] Das spinale epidurale Haematom ist eine Blutansammlung zwischen Dura und Knochen. Die klinische Praesentation ist aehnlich dem akuten Bandscheibenvorfall, die Symptomatik ist allerdings in der Regel progredient. In der CT stellt sich ein frisches Haematom hyperdens dar. Die MRT ist die Methode der Wahl zur Diagnose spinaler epiduraler Haematome und kann die Ausdehnung sowie auch das Ausmass der Kompression darstellen. Die wichtigste Differenzialdiagnose vom epiduralen Haematom ist das epidurale Empyem. (orig.)

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    We report a case of subcorneal hematomas caused by excessive video game play in a 19-year-old man. The hematomas occurred in a setting of thrombocytopenia secondary to induction chemotherapy for acute myeloid leukemia. It was concluded that thrombocytopenia subsequent to prior friction from heavy use of a video game controller allowed for traumatic subcorneal hemorrhage of the hands. Using our case as a springboard, we summarize other reports with video game associated pathologies in the medical literature. Overall, cognizance of the popularity of video games and related pathologies can be an asset for dermatologists who evaluate pediatric patients.

    Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described inflammatory disease of the CNS with a predilection for the hindbrain and responsive to immunotherapy. Five further cases are described with detailed pathology and long term evaluation. CLIPPERS does not represent a benign condition, and without chronic immunosuppression the disease may relapse. The radiological distribution is focused not only in the pons but also in the brachium ponti and cerebellum. Pontocerebellar atrophy occurred early, even in cases treated promptly. Significant cognitive impairment was seen in some cases and was associated with additional cerebral atrophy. The pathology included distinctive histiocytic as well as lymphocytic components and evidence of neuro-axonal injury. Additional subclinical systemic findings on investigation were identified. Relapse was associated with withdrawal of corticosteroids, and disability was least marked in cases where both the presentation and relapses were treated promptly. We propose that the title of the syndrome be amended to chronic lymphocytic inflammation with pontocerebellar perivascular enhancement responsive to steroids to more accurately reflect the distribution of the radiological findings.

    Full Text Available Victoria Cui,1 Timur Kouliev2 1Washington University School of Medicine, St Louis, MO, USA; 2Emergency Department, Beijing United Family Hospital, Beijing, China Abstract: Acute subdural hematoma (SDH resulting from head trauma is a potentially life-threatening condition that requires expedient diagnosis and intervention to ensure optimal patient outcomes. Rapidly expanding or large hematomas, elevated intracranial pressure, and associated complications of brain herniation are associated with high mortality rates and poor recovery of neurological function. However, smaller bleeds (clot thickness <10 mm or hematomas occurring in infrequent locations, such as the tentorium cerebelli, may be difficult to recognize and patients may present with unusual or subtle signs and symptoms, including isolated cranial nerve palsies. Knowledge of neuroanatomy supported by modern neuroimaging can greatly aid in recognition and diagnosis of such lesions. In this report, we present a case of isolated oculomotor nerve palsy resulting from compressive tentorial SDH following blunt head trauma, review the literature concerning similar cases, and make recommendations regarding the diagnosis of SDH in patients presenting with isolated cranial nerve palsies. Keywords: head injury, oculomotor, palsy, subdural hematoma, trauma, tentorium, cerebral herniation, intracranial hemorrhage

    Postoperative epidural hematomas developed far from the operative field are generally recognized as a complication of ventriculo-peritoneal shunt, ventricular drainage or suboccipital craniotomy. It is very rare but may occur after supratentorial craniotomy on the contralateral side. Five such cases are presented with a review of the relevant literature. The mechanism of this complication is not clearly understood. In hydrocephalus, these massive epidural hematomas are probably caused by dura-skull detachment when the brain volume is strikingly reduced by a decompressive procedure. On rare occasions, pins of head rest may detach the dura and cause epidural hematomas. When sudden brain swelling during craniotomy is encountered, attention should be directed not only to intracerebral hemorrhage but also epidural hematoma developed on the contralateral side.

    We report a case of a patient receiving chronic oral anticoagulant therapy with Warfarin who presented with acute intestinal obstruction. Computed tomography showed intramural duodenal hematoma. Treatment was conservative with correction of the coagulation parameters and observation. This case exemplifies the usefulness of conservative therapy and computed tomography in patients with acute small bowel obstruction receiving anticoagulant therapy. (author)

    Full Text Available Traumatic acute subdural hematoma (ASDH is generally addressed by craniotomy under general anesthesia. We report a patient whose traumatic ASDH was treated under local anesthesia by one-burr-hole endoscopic surgery. This 87-year-old woman had undergone coil embolization for a ruptured right middle-cerebral artery aneurysm and placement of a ventriculoperitoneal shunt for normal pressure hydrocephalus 5 years earlier. Upon admission, she manifested consciousness disturbance after suffering head trauma and right hemiplegia. Her Glasgow Coma Scale score was 8 (E2V2M4. Computed tomography (CT demonstrated a thick, left-frontotemporal ASDH. Due to her advanced age and poor condition, we performed endoscopic surgery rather than craniotomy to evacuate the ASDH. Under local anesthesia, we made a burr hole in her left forehead and increased its size to 15 mm in diameter. After introducing a transparent sheath into the hematoma cavity with a rigid endoscope, the clot was evacuated with a suction tube. The arterial bleeding point was electrically coagulated. A postoperative CT scan confirmed the reduction of the hematoma. There was neither brain compression nor brain swelling. Her consciousness disturbance and right hemiplegia improved immediately. Endoscopic surgery may represent a viable method to address traumatic intracranial hematomas in some patients.

    Currently, the lack of a universal and specific marker of clonality hampers the diagnosis and classification of chronic expansions of natural killer (NK) cells. Here we investigated the utility of flow cytometric detection of aberrant/altered NK-cell phenotypes as a surrogate marker for clonality, in the diagnostic work-up of chronic lymphoproliferative disorders of NK cells (CLPD-NK). For this purpose, a large panel of markers was evaluated by multiparametric flow cytometry on peripheral blood (PB) CD56(low) NK cells from 60 patients, including 23 subjects with predefined clonal (n = 9) and polyclonal (n = 14) CD56(low) NK-cell expansions, and 37 with CLPD-NK of undetermined clonality; also, PB samples from 10 healthy adults were included. Clonality was established using the human androgen receptor (HUMARA) assay. Clonal NK cells were found to show decreased expression of CD7, CD11b and CD38, and higher CD2, CD94 and HLADR levels vs. normal NK cells, together with a restricted repertoire of expression of the CD158a, CD158b and CD161 killer-associated receptors. In turn, NK cells from both clonal and polyclonal CLPD-NK showed similar/overlapping phenotypic profiles, except for high and more homogeneous expression of CD94 and HLADR, which was restricted to clonal CLPD-NK. We conclude that the CD94(hi)/HLADR+ phenotypic profile proved to be a useful surrogate marker for NK-cell clonality.

    Full Text Available The T cell co-receptor CD8αβ enhances T cell sensitivity to antigen, however studies indicate CD8αα has the converse effect and acts as a co-repressor. Using a combination of Thymic Leukaemia antigen (TL tetramer, which directly binds CD8αα, anti-CD161 and anti-Vα7.2 antibodies we have been able for the first time to clearly define CD8αα expression on human CD8 T cells subsets. In healthy controls CD8αα is most highly expressed by CD161 bright (CD161++ mucosal associated invariant T (MAIT cells, with CD8αα expression highly restricted to the TCR Vα7.2+ cells of this subset. We also identified CD8αα-expressing populations within the CD161 mid (CD161+ and negative (CD161- non-MAIT CD8 T cell subsets and show TL-tetramer binding to correlate with expression of CD8β at low levels in the context of maintained CD8α expression (CD8α+CD8βlow. In addition, we found CD161-CD8α+CD8βlow populations to be significantly expanded in the peripheral blood of HIV-1 and hepatitis B (mean of 47% and 40% of CD161- T cells respectively infected individuals. Such CD8αα expressing T cells are an effector-memory population (CD45RA-, CCR7-, CD62L- that express markers of activation and maturation (HLA-DR+, CD28-, CD27-, CD57+ and are functionally distinct, expressing greater levels of TNF-α and IFN-γ on stimulation and perforin at rest than their CD8α+CD8βhigh counterparts. Antigen-specific T cells in HLA-B*4201+HIV-1 infected patients are found within both the CD161-CD8α+CD8βhigh and CD161-CD8α+CD8βlow populations. Overall we have clearly defined CD8αα expressing human T cell subsets using the TL-tetramer, and have demonstrated CD161-CD8α+CD8βlow populations, highly expanded in disease settings, to co-express CD8αβ and CD8αα. Co-expression of CD8αα on CD8αβ T cells may impact on their overall function in-vivo and contribute to the distinctive phenotype of highly differentiated populations in HBV and HIV-1 infection.

    Rosenberry, Clark; Angelidis, Matthew; Devita, Diane

    2010-09-01

    Only a few cases of nontraumatic orbital subperiosteal hematoma due to scuba diving have been reported, and this is the first of such cases that underwent surgical intervention. This injury results from negative pressure within the face mask, suctioning orbital tissues into the mask after incomplete equilibration of pressure on descent. Valsalva maneuver is a second mechanism implicated in the etiology of this injury. Recognition of this injury is of the utmost importance because vision loss is a possible complication if there is compression of the optic nerve or increased intraocular pressure. In many cases of nontraumatic orbital hematoma, conservative management is adequate; however, this case was an exception due to worsening exam findings. Divers may be able to prevent this injury by frequent and gentle equilibration of mask pressure on descent.

    Anticoagulated patients may have a characteristic syndrome of femoral neuropathy from an iliacus muscle hematoma. They may present with urologic signs and symptoms, including groin, flank and thigh pain, groin tenderness, an iliac fossa mass and hematuria. Urography may reveal an enlarged psoas shadow and hydronephrosis from ureteral obstruction. Prompt diagnosis is essential so that early operative decompression of the femoral nerve can be done. The urologist has an important role in the diagnosis and treatment of this syndrome.

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk

  18. Hematoma shape, hematoma size, Glasgow coma scale score and ICH score: which predicts the 30-day mortality better for intracerebral hematoma?

    Full Text Available To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS score, and intracerebral hematoma (ICH score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality.This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant.The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018, 0.715 (P = 0.0008 (by ABC/2 to 0.738 (P = 0.0002 (by CAVA, 0.877 (P<0.0001 (by ABC/2 to 0.882 (P<0.0001 (by CAVA, and 0.912 (P<0.0001, respectively.Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score.

    @@ Retroperitoneal hematoma is an obligatory complication in pelvic ring fracture.1 In most cases, the bleeding originates from venous vessels of the presacral plexus, small arteries and veins from fracture fragments. External fixation of the pelvis can control blood loss by reducing diastasis and dramatically decreasing the volume of the pelvis. But this tamponade effect can not prevent the presence of hematoma in the adjoining retroperitoneal space. It is well known that complication of retroperitoneal hematoma is infection and sepsis.

    Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count. She was successfully managed by craniotomy and evacuation of subdural hematoma with intraoperative transfusion of platelets. The acute spontaneous subdural hematoma in her was probably related to the bleeding diathesis due to thrombocytopenia associated with chemotherapy.

    Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

    Renal angiomyolipoma (AML) is a benign tumor, they are generally asymptomatic or can manifested by abdominal pain, palpable mass or hematuria. We report an uncommoun case of 65 years old women who consulted for retroperitoneal hemorrhage by spontaneous rupture of renal AML with palpable mass. The ultrasound and CT abdominopelvic scan were performed in the preoperative diagnosis and showed a typical right renal AML with retroperitoneal hematoma. The right nephrectomy by transperitoneal approach was performed with a good follow-up. The histological examination confirmed the diagnosis for renal AML. About this case, the authors discuses the diagnosis and the management for AML with retroperitoneal hemorrhage.

    Full Text Available We describe an interesting case of intramural duodenal hematoma in an otherwise healthy male who presented to emergency room with gradually progressive abdominal pain, nausea, and vomiting. This condition was missed on initial evaluation and patient was discharged from emergency room with diagnosis of acute gastritis. After 3 days, patient came back to emergency room and abdominal imaging studies were conducted which showed that patient had intramural duodenal hematoma associated with gastric outlet obstruction and pancreatitis. Hematoma was the cause of acute pancreatitis as pancreatic enzymes levels were normal at the time of first presentation, but later as the hematoma grew in size, it caused compression of pancreas and subsequent elevation of pancreatic enzymes. We experienced a case of pancreatitis which was caused by intramural duodenal hematoma. This case was missed on initial evaluation. We suggest that physicians should be more vigilant about this condition.

    Acute epidural hematoma not associated with head injury is rarely encountered and is known as spontaneous epidural hematoma. To our knowledge, only five cases with epidural hematoma after open-heart surgery have been published. Pathogenesis and preventive measures have not yet been determined. We report a case of such spontaneous epidural hematoma and consider the possible pathogenesis. A 12-year-old female received a radical operation for severe subaortic stenosis. The intraoperative course was uneventful except for massive hemorrhage which was adequately controlled. Postoperatively, she was moved to the CCU still not having aroused from anesthesia. Eleven hours later, it was found that her pupils were fixed and dilated. CT scan demonstrated a huge bifrontal epidural hematoma with disappearance of the basal cistern. Even though immediate emergency evacuation was performed, the patient died of acute brain swelling four days after the operation.

    An 88-year-old female presented with a left thigh pain and dysuria. She visited our hospital 2 week after she noticed her symptoms. She stated that she might have a low-energy fall, but she could not identify the exact onset. Her radiograph of the pelvis (Figure 1) showed displaced left pubic ramus fracture. Her computed tomographic scanning of the pelvis (Figure 2) showed massive intrapelvic hematoma (axial size, 11 cm by 5 cm) around the fracture site, although she did not use any anticoagulants. Because her bone mineral density was 0.357 g/cm{sup 2}, and T score was -4.8 SD, she started a bisphosphonate therapy. She received a bed-rest physical therapy for 6 weeks, and the hematoma regressed spontaneously. She started full weight bearing after 6 weeks, and walked by a walker after 8 weeks. Although it is extremely rare to develop massive chronic intra-pelvic hematoma after a lowenergy pubic ramus fracture without any use of anticoagulants, it may occur in elderly and severely osteoporotic patient.

    Full Text Available Acute posterior fossa subdural hematomas are rare and most of them are trauma-related. Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. We report on the case of 57-year-old Iranian man who developed sudden severe occipital headache, drowsiness, repeated vomiting, and instability of stance and gait. He was neither hypertensive nor diabetic. No history of head trauma was obtained and he denied illicit drug or alcohol ingestion. A preliminary diagnosis of acute intra-cerebellar hemorrhage was made. His CT brain scan revealed an acute right-sided, extra-axial, crescent-shaped hyperdense area at the posterior fossa. His routine blood tests, platelets count, bleeding time, and coagulation profile were unremarkable. The patient had spontaneous acute infratentorial subdural hematoma. He was treated conservatively and discharged home well after 5 days. Since then, we could not follow-up him, clinically and radiologically because he went back to Iran. Our patient’s presentation, clinical course, and imaging study have called for conservative management, as the overall presentation was relatively benign. Unless the diagnosis is entertained and the CT brain scan is well-interpreted, the diagnosis may easily escape detection.

    Full Text Available Sciatica is defined as pain in the sciatic nerve distribution. The most common reason of sciatica is radiculopathy due to lumbar disc hernia. Other causes can be congenital, acquired, infectious, neoplastic, or inflammatory. The piriformis syndrome is another cause. The pain starts in an insidious manner when the cause of sciatica is an extraspinal tumor. It is intermittent at first but a constant and progressive pain that does not decrease with position or rest gradually develops in all patients. The possibility of an intraabdominal or pelvic mass should always be considered and the relevant tests requested when the cause of the sciatica cannot be explained. We present an 83-year-old male who presented with non-traumatic and non-vascular lumbosacral plexopathy due to a large hematoma in the left adductor muscle following the use of warfarin sodium.

    Full Text Available ABSTRACTIn Latin America, Bothrops envenomation is responsible for the majority of accidents caused by venomous snakes. Patients usually present local edema, bleeding and coagulopathy. Visceral hemorrhage is extremely rare and considered a challenge for diagnosis and management. We report the first case of hepatic hematoma owing to the bothropic envenomation in a 66-year-old man who was bitten in the left leg. He presented local edema, coagulopathy, and acute kidney injury. Radiological findings suggested hepatic hematoma, with a volume of almost 3 liters. The hepatic hematoma was gradually absorbed without the need for surgical intervention with complete resolution in 8 months.

    Traumatic duodenal hematoma is a rare condition that is encountered in the paediatric age group following blunt abdominal trauma. It poses both a diagnostic and therapeutic challenge. The main concern is increased morbidity secondary to delayed diagnosis and associated occult injuries to the adjacent structures. Most of these hematomas resolve spontaneously with conservative management, and the prognosis is good. We present a case of a 15-year-old boy who had a delayed presentation of duodenal hematoma and acute pancreatitis, which was treated conservatively with complete resolution.

    Intracerebellar hemorrhage is very rare in term infants and only severe cases with massive intracranial hemorrhage, posthemorrhagic hydrocephalus and clinical deterioration due to increased intracranial pressure require neurosurgical evacuation. In recent adult studies endoscopic hematoma evacuation has been shown as a rapid, effective, and safe technique. A term newborn hospitalized for meconium aspiration syndrome showed hypertonia, jitteriness and abnormal amplitude integrated electroencephalogram findings. He was diagnosed with cerebellar hematoma which caused hydrocephalus by cranial magnetic resonance imaging (MRI). The hematoma was successfully evacuated neuroendoscopically as the first case in literature to our knowledge. Neurologic, a-EEG and MRI findings resolved.

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

    Full Text Available Bleeding and hematoma formation is rarely reported in percutaneous vertebroplasty procedure. An 84 year old male presented with a large paraspinal muscle hematoma after a percutaneous vertebroplasty. The patient had neither any prior bleeding disorder nor any anticoagulant treatment. Vital signs of the patient were unstable, and his hemoglobin level decreased daily. After a month of conservative treatment, including transfusion, cryotherapy, pain control and bed rest, his hemoglobin level remained stable and he showed relief from pain. Four months later, hematoma resolved spontaneously and he could walk without back pain.

    Spontaneous rectus sheath hematoma (SRSH) is a rare entity that mimics acute abdomen. Rectus sheath hematoma is the accumulation of blood in rectus sheath due to muscle or epigastric vessel injury. However, SRSH without a trauma or anticoagulation is rare. It frequently mimics acute abdomen and it may lead to misdiagnosis and unnecessary laparotomy. In this article, we described two cases of SRSH with their diagnostic and therapeutic strategy. Both of our patients in report were neither consumed antiplatelet nor coagulopathy. They both had abdominal muscle straining before their symptoms pre-sentation. We hypothesized that the SRSH may be induced by rectus muscle injury secondary to inappropriate straining or posture. To diagnose SRSH, clinical findings are important but radiologic imaging such as computed tomography, can be diagnostic. In expanding SRSH, percutaneous arterial embolization of epigastric artery is useful to secure the bleeding. If embolization is not feasible, surgical exploration hemostasis is curative. In non-expanding SRSH, it can be managed nonoperatively. SRSH is an important initial differential for acute abdomen. Radiologic imaging helps in diagnosis. Stable SRSH can be managed conservatively with good outcome.

    BACKGROUND: Traditionally, cranial perforate-rinse-dram operation and tube drainage were often used in the treatment of chronic subdural hematoma in the elderly, recently,instead of which oxygen-exchange therapy through dural puncture via cranium is more and more used.OBJECTIVE: To investigate the reliability and safety of the new operation-method using oxygen-exchange in treating the older people with chronic subdural hematoma in comparison with traditional cranial perforate-rinse-dram operation.DESIGN: Retrospective case analysis.SETTING: The Department of Neurosurgery, the Second Clinical College of China Medical University.PARTICIPANTS: Eleven male patients (meanly 62 years of age)who had undertaken oxygen-exchange therapy via skull without drain tube in the Department of Neurosurgery, Second Clinical College of China Medical College from January 1997 to December 2004 were enrolled in the study, with an average disease history of 1.5 months. Among them, 10 subjects suffered from head injury to different extent within 7 weeks on average. Main chief complaint was headache, and Unilateral limb asthenia above Ⅳ was found in 5 cases asking for medical service. As shown by CT and MRI, all the subjects were diagnosed as having chronic subdural hematoma located at supratentorium, 5 cases in the right side and 6 in the left side. Volume of hematom was calculated as the following formula: volume of hematom=length×width×number of layers (1 cm thick for one layer). And the range of volume was from 70 mL to 140 mL, and the average value was 105 mL. The hematom in all the cases was found to move to the midline to different extents.METHODS: Patients in lateral recumbent position were undertaken boring at the CT-located thickest area with bone awl of 0.4-0.5 cm under local anesthesia. After boring, 14-size lumbar puncture needle with trochar was used to acupuncture dura mater then moving the needle core so that blood was discharged. Then 10 mL medical oxygen was perfused

    Magnetic resonance is highly sensitive for the detection of intraparenchymatous hemorrhage. The evolution of hematoma over time translates into changes in signal intensity. This means that we can determine when the hematoma presented and, in addition. follow its course. On the other hand, many intracranial processes developing association with hemorrhage, the recognition of which is, in some cases, of importance. We have studied 60 cerebral hematomas and have described the changes that will take place in their signal and the reasons for them. (author)

    (25 vs. 9.5%, p = 0.1311 compared to patients with high LDL values. Conclusions: Our data suggest that neither chronic daily alcohol use nor a low LDL level in combination with daily alcohol use can be used to predict ICH growth. Daily alcohol use was associated with untreated hypertension and higher BP on presentation. A low LDL level in combination with daily alcohol use may be linked with larger and more severe ICH, but we were unable to demonstrate a relationship with hematoma expansion or poor clinical outcome. The role of LDL in vessel fragility and clot stabilization needs to be further explored before concluding that a low LDL level confers risk of bleeding.

    We report an extremely rare case of traumatic cervical spinal subdural hematoma not related to intracranial injury. There has been no report on traumatic cervical spinal subdrual hematoma not related to intracranial injury. A 27-year-old female patient was admitted to our emergency room due to severe neck pain and right arm motor weakness after car collision. On admission, she presented with complete monoplegia and hypoesthesia of right arm. Magnetic resonance imaging (MRI) revealed subdural hematoma compressing spinal cord. Lumbar cerebrospinal fluid (CSF) analysis revealed 210,000 red blood cells/mm(3). She was managed conservatively by administrations of steroid pulse therapy and CSF drainage. Her muscle power of right arm improved to a Grade III 16 days after admission. Follow-up MRI taken 16th days after admission revealed almost complete resolution of the hematoma. Here, the authors report a traumatic cervical spinal SDH not associated with intracranial injury.

    We report a rare case of a meningioma causing acute hematoma. A 67-year-old woman presented with sudden headache. No evidence of trauma was seen. CT demonstrated a subdural hematoma in the convexity of the fronto-temporal lobe. Magnetic resonance imaging showed marked signal heterogeneity in the convexity of the frontal lobe. One week later, the patient underwent hematoma evacuation and tumor resection including the attached dura mater. The histological diagnosis was meningothelial meningioma. The clot was connected directly to the tumor and the origin of the subdural hematoma was identified as the meningioma. Postoperative course was uneventful, and the headache improved. Meningiomas have a relatively benign course but rarely present with hemorrhage. Surgical exploration is the effective and recommended treatment.

    We present a patient with a spontaneous iliacus muscle hematoma, appearing immediately after a minor physical maneuver, presenting with pain and femoral neuropathy initially evidenced by massive quadriceps muscle fasciculations. A magnetic resonance imaging (MRI) study of the pelvic area confirmed the diagnosis, showing a hematoma secondary to a partial muscle tear. The patient was managed conservatively, and the continuous muscle activity ceased in 3 days, with progressive improvement of the pain and weakness. The recovery was complete. Femoral neuropathy is uncommon and usually due to compression from psoas muscle mass lesions of diverse nature, including hematomas. Usually subacute, femoral neuropathy may present acutely in cases of large or strategically placed compressive femoral nerve lesions, and may require surgical evacuation. The case presented herein is remarkable since the muscle hematoma appeared after a nonviolent maneuver, fasciculations were present at onset, and conservative management was sufficient for a full recovery.

    Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

    An iliopsoas hematoma can occur either spontaneously or secondary to trauma or bleeding tendency due to hemophilia and anticoagulant therapy. Although liver cirrhosis is commonly associated with coagulopathy, iliopsoas hematoma is very rare. We herein, present a case of bilateral iliopsoas hematoma in a patient with alcoholic cirrhosis, and review the literature on muscle hematoma associated with cirrhosis. A 56-year-old man with alcoholic cirrhosis was admitted in a state of shock with anemia. The cause of anemia could not be detected, and the patient was treated conservatively. The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography, the latter of which did not include the iliopsoas muscle. He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy. An iron stain was positive in the iliopsoas muscle. Eight cases of muscle hematoma associated with cirrhosis, including the present case, were found in a review of the literature. Four of these cases involved the rectus abdominis muscle, 3 involved the iliopsoas muscle and 1 involved combined muscles. Alcoholic cirrhosis accounted for 75% of the cases. One case (12.5%) was associated with virus-related cirrhosis, and another with combined virus-and alcohol-related cirrhosis. The mortality rate was 75% despite early diagnosis and low risk scores for cirrhosis. Muscle hematoma in patients with cirrhosis isclosely related to alcoholism, and the mortality rate of the condition is extremely high. In conclusion, muscle hematoma should be recognized as an important complication of cirrhosis.

    Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out. Spontaneous spinal epidural hematoma (ASSEH is a rare but dramatic cause of neurological impairment. In this article we report a fortunate case of complete recovery after an unusual spine cord decompression. We also review the current literature concerning diagnosis and treatment of ASSEH.

    2011-11-01

    Full Text Available Abstract Background Previously proposed classifications for carotid plaque and cerebral parenchymal hemorrhages are used to estimate the age of hematoma according to its signal intensities on T1w and T2w MR images. Using these classifications, we systematically investigated the value of cardiovascular magnetic resonance (CMR in determining the age of vessel wall hematoma (VWH in patients with spontaneous cervical artery dissection (sCAD. Methods 35 consecutive patients (mean age 43.6 ± 9.8 years with sCAD received a cervical multi-sequence 3T CMR with fat-saturated black-blood T1w-, T2w- and TOF images. Age of sCAD was defined as time between onset of symptoms (stroke, TIA or Horner's syndrome and the CMR scan. VWH were categorized into hyperacute, acute, early subacute, late subacute and chronic based on their signal intensities on T1w- and T2w images. Results The mean age of sCAD was 2.0, 5.8, 15.7 and 58.7 days in patients with acute, early subacute, late subacute and chronic VWH as classified by CMR (p Conclusions Signal intensities of VWH in sCAD vary over time and multi-sequence CMR can help to determine the age of an arterial dissection. Furthermore, findings of this study suggest that the time course of carotid hematomas differs from that of cerebral hematomas.

    The objective of this study was to evaluate the age distribution, mode of injury, type of hematomas, and their surgical outcome in patients with bilateral traumatic head injuries. The present study included 669 cases of traumatic head injury who presented at the neurosurgery emergency out of which 94 cases had bilateral head injuries from the period of August 2009 to April 2014. The data from the hospital computerized database were retrospectively analysed. Cases of bilateral traumatic head injury included 94 patients out of which 88.29 % (n = 83) were males and 11.70 % (n = 11) were females. Commonest mode of injury was road traffic accident in 56.38 % (n = 53) followed by fall from height in 29.78 % (n = 28). In our study, 25.53 % patients had epidural hematoma (EDH) with intracerebral hematoma (ICH) or contusion (n = 24), followed by EDH with subarachnoid hemorrhage (SAH) in 18.08 % (n = 17). At the time of discharge, all those patients managed conservatively had good Glasgow outcome scale (GOS) while with surgical intervention 58 % patients had good GOS, 19 % had moderate disability, and 9 % remained with severe disability. In cases of bilateral hematomas, EDH is most common and should be managed in neurosurgical emergency. Other combinations of bilateral intracranial hematomas should be managed according to the surgical indication and serial CT imaging.

    Splenic hematomas are infrequent complications of acute pancreatitis. In some cases, local factors that may play a role in the pathogenesis of the hematoma (thrombosis of the splenic artery or veins, intrasplenic pseudocysts, perisplenic adhesions, enzymatic digestion) are found. In the absence of local factors, the etiology of splenic hemorrhage remains unknown. We report two cases of splenic hematoma occurring during an acute necro-hemorrhagic pancreatitis associated with renal failure that required renal replacement therapy (hemodialysis and continuous arteriovenous hemodialysis). In both cases, more than half of splenic parenchyma was affected by multiple infarctions. No local factors responsible for the splenic abnormalities were detected in either case. Thrombosis of the splenic arterial microcirculation and a coagulation disorder consistent with disseminated intravascular coagulation was detected in one patient. In the second patient, coagulation disorders secondary to either liver disease, pancreatitis and its septic complications, or extracorporeal circuit heparinization for renal replacement therapy were present. Coagulation disorders should be considered whenever a splenic hematoma is found in a patient with acute pancreatitis. Disseminated intravascular coagulation may be the etiology of a splenic hematoma in acute pancreatitis.

    Background: In much of the Western hemisphere, mortality from traumatic acute extradural hematomas (AEDH) has been drastically brought down toward 0%. This is still not the case however in most developing countries. Case Description: This report represents a tragi-comic tale of two cases of traumatic AEDH managed by an academic neurosurgeon in a neurosurgically ill-resourced private health facility during a nationwide industrial strike action preventing clinical-surgical care in the principal author's University Teaching Hospital. A young man presented with altered consciousness, Glasgow Coma Score (GCS) 14/15, following a road accident. The cranial computed tomography (CT) scan was obtained only 9 h after its request, long after the man had actually deteriorated to GCS 7/15 with pupillary changes. The neurosurgeon, summoned from the nearby University Teaching Hospital for the operative care of this man, arrived on-site and was about moving the patient into the operative room when he took the final breaths and died, all within 2 h of the belated neuroimaging. This scenario repeated itself in the same health facility just 24 h later with another young man who presented GCS 7/15 and another identical CT evidence of traumatic AEDH. With more financially able relations, the diagnostic/surgical care of this second patient was much more prompt. He made a very brisk recovery from neurosurgical operative intervention. He is alive and well, 5-month postoperative. Conclusions: In most low-resourced health systems of the developing countries, a significant proportion of potentially salvageable cases of AEDH still perish from this disease condition.

    Intramural hematomas (IMH) are regarded as a hemorrhage into the aortic wall. In general a traumatic form can be differentiated from a spontaneous non-traumatic. There is a predisposition of IMH with arterial hypertension and mesoectodermal dysplastic syndromes. The diagnosis is established with the clinical presentation in combination with the findings of different imaging modalities. Acute and subacute discomfort associated with a tendency of collaps are considered as typical presenting complaints. A semicircular or concentric thickening of the aortic wall with the absence of blood flow or a dissection membran are typical findings in transesophageal echocardiography, computed tomography and magnetic resonance tomography. From a differential diagnostic point of view a distinction from atherosclerotic wall changes, intraluminal thrombi and inflammatory aortic diseases is essential. The IMH is considered as an early presentation of aortic dissection, put into and treated according to the Stanford classification. In the course of natural history an IMH can disappear, rupture or progress into a classic aortic dissection. (orig.) [German] Das intramurale Haematom (IMH) ist eine Einblutung in die Aortenwand. Grundsaetzlich kann zwischen traumatischer Genese und einer atraumatischen spontanen Form unterschieden werden. Praedisponierend sind arterielle Hypertension und mesoektodermale Dysplasiesyndrome. Die Diagnose ergibt sich aus der Klinik und den Befunden in den bildgebenden Verfahren. Zu den klinischen Symptomen zaehlen akut oder subakut auftretende Schmerzen, assoziiert mit einer Kollapsneigung. Typische Befunde in der transoesophagealen Echokardiographie, der Computer- oder der Magnetresonanztomographie sind eine halbmondfoermige oder konzentrische Wandverdickung der Aorta ohne Nachweis von Blutfluss oder einer Dissektionsmembran mit Dichtewerten bzw. Signalintensitaeten in Abhaengigkeit vom Alter der Einblutung. Differenzialdiagnostisch ist eine Abgrenzung

    This report presents the case of a 59-year-old man with sudden severe pain in the right lower abdomen after manually reducing the right indirect inguinal hernia who had bilateral indirect inguinal hernia for 5 years. A subsequent contrast computed tomography scan with contrast of the abdomen and pelvis revealed a significant extensive retroperitoneal hematoma at the abdomen and pelvis of the right side. There was contrast leaked out, which was suspected from inferior epigastric artery. He underwent successful laparotomy. The bleeding ruptured inferior epigastric artery at the interior side of the deep inguinal ring was found, the deep inguinal ring was avulsed, ligature of the inferior epigastric artery and removal of the retroperitoneal hematoma were done, and the patient was discharged from hospital on the seventh postoperative day. This is the first report in the literature on retroperitoneal hematoma caused by manual reduction of indirect inguinal hernia.

    Postpartum hemorrhage is an obstetrical emergency that represents the leading cause of maternal mortality. Severe hemorrhagic complications that could appear postpartum are the abdomino-pelvic hematomas, which result from the rupture of the pelvic vessels. We reported a very rare case of puerperal retroperitoneal subserosal hematoma of sigmoid colon following vaginal delivery, which was successfully managed by conservative methods. As far as we know, there are only a few case reports of intramural hematoma of sigmoid colon in literature, having other etiologies than vaginal delivery trauma. The particularities of the case consisted in the association of hemangiomas and the low risk thrombophilia. Diagnosis was based on the clinical exam and the paraclinical founding. Laparotomy is generally considered the last choice, in life threatening cases with hemodynamic instability, compression signs, and presence of contrast leakage on noninvasive imaging methods, but avoiding colonic resection after dissection represented the true challenge of the case.

    Full Text Available We report successful outcome of a huge post- trabeculectomy intra-bleb hematoma and hyphema that occurred following digital ocular compression. The patient was a 64-year-old lady suffering from bilateral primary angle closure glaucoma and cataract. She was on anti-platelet therapy. She underwent single-site phacoemulsification, intra-ocular lens implantation and trabeculectomy with mitomycin C in the right eye. The trabeculectomy was under-filtering. She was asked to perform digital ocular compression thrice daily. On 15 th post-operative day, she presented with a huge intra-bleb hematoma and hyphema. The hematoma did not respond to conservative measures and was drained to prevent bleb failure. We recommend caution in the consideration of digital ocular compression in patients on prophylactic anti-coagulation.

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

    Spinal epidural hematoma and spinal epidural abscess are rare surgical emergencies resulting in significant neurologic deficits. Making the diagnosis for spinal epidural hematoma and spinal epidural abscess can be challenging; however, a delay in recognition and treatment can be devastating. The objective of this retrospective analysis study was to identify risk factors for an adverse outcome for the provider. The LexisNexis Academic legal search database was used to identify a total of 19 cases of spinal epidural hematoma and spinal epidural abscess filed against medical providers. Outcome data on trial verdicts, age, sex, initial site of injury, time to consultation, time to appropriate imaging studies, time to surgery, and whether a rectal examination was performed or not were recorded. The results demonstrated a significant association between time to surgery more than 48 hours and an unfavorable verdict for the provider. The degree of permanent neurologic impairment did not appear to affect the verdicts. Fifty-eight percent of the cases did not present with an initial deficit, including loss of bowel or bladder control. All medical professionals must maintain a high level of suspicion and act quickly. Physicians who are able to identify early clinical features, appropriately image, and treat within a 48 hour time frame have demonstrated a more favorable medicolegal outcome compared with their counterparts in filed lawsuits for spinal epidural hematoma and spinal epidural abscess cases.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    The etiology and proper treatment of symptomatic subacute subdural hematomas remains to be elucidated. We describe two cases of this entity successfully treated with small craniotomy and evacuation. Both patients initially treated conservatively for traumatic thin subdural hematomas because of poor medical condition and mild neurological symptoms, but suffered abrupt neurological deterioration between 2 and 3 weeks after the admission. CT scan showed decreased density of hematomas with minimal increase in volume, and significant swelling of ipsilateral cerebral hemisphere. Urgent two-burr-hole small craniotomy was effective for evacuation of partially organized hematoma. During surgery, definite hematoma membrane was not confirmed. Postoperatively, brain swelling rapidly disappeared and both patients discharged ambulatory without neurological deficit. The present cases are a reminder of this peculiar type of hematoma in patients with delayed neurological deterioration after nonsurgical management of acute subdural hematoma. The rationale for use of small craniotomy is discussed in terms of current understanding of pathogenetic mechanism for this unusual condition.

    Conclusions: The presence of a fracture over the MMA and intraparenchymal hematoma should prompt suspicion for a traumatic pseudoaneurysm. Pseudoaneurysms of the MMA can cause catastrophic bleeding, and prompt treatment is necessary. Endovascular embolization is an effective method that decreases the hemorrhage risk of MMA pseudoaneurysms.

    2008-01-01

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

    We report a patient with minor head trauma-related bilateral hemispheric subdural hematoma (SDH) and subsequent delayed spinal SDH or presumed migration to the lumbar spine. An acutely confused 88-year-old man presented to the Emergency Department after minor head trauma. Head CT scan revealed a small hemispheric SDH. The patient was admitted for observation. CT scan 6 hours later showed bilateral SDH with extension to the tentorium. Three days later SDH had resolved leaving bilateral subdural hygromas. Local leg weakness localized to the lumbar spine developed on day 6; spinal CT scan and MRI revealed a posterior L5-S1 collection. A pure subacute subdural hematoma compressing the cauda equina was drained after an L5 laminectomy. His lower leg weakness improved. The patient was discharged to rehabilitation two weeks after surgery. Patients with traumatic SDH who develop late-onset neurological deterioration attributable to any region of the spine should be evaluated for spinal SDH.

    The aim of this study was to assess the possibility of revealing intracerebral hematomas (ICH), using MRI, within the first hours after onset and to determine their MRI semiotics features. Thirty animals with experimental ICH were studied. A method of two-stage introduction of autologous blood was used to develop ICH as human spontaneous intracranial hematomas. Within 3-5h after blood introduction to the rat brain. The control MRI was performed in the 3rd and 7th days after blood injections. ICH were definitely identified in the first MRI scans. The MRI semiotics features of acute ICH and their transformations were assessed. The high sensitivity of MRI to ICH as well as the uniform manifestations in all animals were shown. In conclusion, the method has high specificity for acute ICH detection.

    We report a rare case of a patient with spinal epidural hematoma who presented with transient hemiplegia. A 90-year-old man awakened from sleep due to sudden neck pain. Fifteen minutes later, the man experienced progressively worsening weakness in his left hand, and was transported in an ambulance to our hospital. At the hospital, he presented with hemiplegia, and we suspected intracranial disease. Therefore, we performed magnetic resonance imaging (MRI), which revealed no intracranial lesions. Shortly after the MRI, the patient showed no signs of hemiplegia. However, since the severe neck pain persisted, we performed cervical MRI, which showed a high-intensity area at the C2-C5 level, predominantly on the left side. Despite recovery from hemiplegia, we performed a laminectomy of C3-C5 with evacuation of a hematoma at the C2-C6 level. After the surgery, the patient had no neck pain.

    2016-01-01

    Background: Tentorial hematoma is frequently seen in traumatic brain injury (TBI) patients, especially in motorized two-wheeler riders following head injury. However its relevance and prognostic significance are not known. Objective: To evaluate patients of TBI with tentorial hematoma using a simple grading system and attempt to correlate this grading with factors like helmet use and neurological outcome. Materials and Methods: This prospective study over a 1-year period included patients with TBI who had tentorial hematoma in the initial plain head. Patients were divided into three grades based on the initial CT findings: Grade I: Isolated tentorial hematoma, grade II: tentorial hematoma with midline shift but open cisterns and grade III: Tentorial hematoma with effaced cisterns. Clinical and radiological records of patients including admission GCS and GOS at discharge were assessed in all cases. Observations: A total of 1786 patients of TBI were admitted during the study period. Of these, 106 (5.9%) patients had tentorial hematoma. 84.9% (n = 90) were male and 15.1% (n = 16) were female with the mean age being 36.5 years (range 2-66 years). The mean admission GCS was 13, 11 and 8 in patients with grade I, II and III tentorial hematoma respectively. 43.4% (n = 46) of the patients had grade I, 32.1% (n = 34) had grade II and 24.5% (n = 26) patients had grade III tentorial hematoma. Seventy-one patients (84.5%) were riding motorized two wheelers with 63 (89%) wearing helmets. The majority of the patients wearing helmets (58.8%) had grade I hematoma with 35% (n = 22) having grade II hematoma and only 6.3% (n = 4) having grade III hematoma. Overall, there were 20 deaths. 50% (n = 10) of the deaths were in patients with grade III hematoma and 40% (n = 8) of the deaths were in patients with grade II hematoma. There were two (10%) deaths in patients with grade I hematoma (both unrelated to head injury). The mean GOS at the time of discharge was 5, 4.1 and 2.2 in patients

  3. A Case of Spontaneous Spinal Epidural Hematoma Mimicking Stroke

    Directory of Open Access Journals (Sweden)

    Emine Rabia Koç

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

    Intracranial bleeding following stereoelectroencephalography (sEEG) is rare and commonly occurs early after electrode implantation. The authors report the case of a delayed intracranial hematoma following sEEG. This 10-year-old boy was referred to the authors' department to undergo an sEEG study for intractable epilepsy, with the hypothesis of a single localized epileptic zone in the left precentral region. To perform the exploration, 14 depth electrodes were implanted under stereotactic conditions. The results of a postoperative CT scan performed routinely at the end of the surgical procedure were normal. Eight days later, following an epileptic seizure, the child's condition worsened. The neurological examination revealed a left hemiparesis, agitation, and coma due to a right subdural hematoma with intraparenchymal bleeding. Despite a surgical evacuation followed by a decompressive craniectomy, the curative treatments were stopped 1 week later due to severe diffuse ischemic lesions found on MRI studies. This is the first observation of a delayed hematoma following an sEEG procedure. The mechanism underlying this complication remains unclear, but the rupture of a growing pseudoaneurysm caused by the electrode's implantation or the tearing of a neighboring vessel by an electrode were suspected. In consequence, physicians must remain vigilant during the entire sEEG recording period and probably also several days after electrode removal.

    The purpose of this study was to assess the usefulness of CT angiography (CTA) in patients with intracerebral hematoma. Eighteen patients with spontaneous intracerebral hematoma underwent CTA; 20-30 seconds after the onset of an injection of contrast media (100mL), with the use of a power injector, at a rate of 3mL/sec, scanning (30-second continuous exposure and 60-90mm length) was performed with a table speed of 2-3 mm/sec and section thickness of 2mm. The starting point selected was the floor of the sella turcica. The resulting data were reformatted by maximum intensity projection (MIP) after reconstruction at 1-mm intervals, and CTA findings were compared with those of conventional angiography (n=17), surgery (n=6), and postcontrast CT(n=10). The diagnostic findings of CTA included five arteriovenous malformations, two aneurysms, one venous angioma, and one venous sinus occlusion, while the remaining nine patients had no vascular lesion. In all cases, CTA findings correlated well with those of postcontrast CT. In one cases of arteriovenous malformation, however, the feeding artery and draining vein were not definite on CTA, and in one case of sinus occlusion, the full length of the superior sagittal sinus could not be delineated. In patients with spontaneous intracerebral hematoma, CTA is a valuable screening method. (author). 15 refs., 4 figs.

    The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.

    Full Text Available Reports of retropharyngeal hematoma have been scarce in the anesthesiology literature. We report a patient whose trachea was difficult to intubate due to retropharyngeal hematoma after stabbing to the neck. A woman with a knife injury to the common carotid artery required emergency carotid arterioplasty. When tracheal intubation was attempted, marked swelling of the posterior pharyngeal wall made the vocal cords impossible to visualize. Preoperative computed tomography showed a retropharyngeal hematoma. The patient required mechanical ventilation for 2 days.

    Spinal anesthesia is widely used for many obstetric, gynecological, orthopedic, and urological operations. Subdural hematomas may occur after trauma and are associated with high morbidity and mortality rates. Postdural puncture headache (PDPH) is a benign condition and the most frequent complication of spinal anesthesia. The high rate of headache after spinal anesthesia may mask or delay the diagnosis of subdural hematoma. The true incidence of postdural puncture subdural hematoma (PDPSH) is ...

    Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included (International Classification of Diseases 10th Revision codes I61.0-I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with Panticoagulants or antiplatelet agents was documented in 16.3% and 25.1%, respectively. Overall in-hospital mortality was 23.2%. In-hospital mortality was decreased in operatively treated patients compared to conservatively treated patients (11.6% versus 24.0%; Pantiplatelet pre-treatment had a significantly higher risk of death during the hospital stay after hematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24-4.97; P=0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79-1.09; P=0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.

    Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmonary embolism, was administered an enema resulting in severe abdominal pain unresponsive to blood transfusion. A sigmoid colectomy with end colostomy was performed. Although rare, colonic and recto-sigmoid hematomas should be considered as a possible diagnosis for adults with abdominal pain on anticoagulant therapy. PMID:28108634

    Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

    This study aims to describe the unique characteristics of absorption fever in patients with a hematoma after percutaneous renal biopsy (PRB) and distinguish it from secondary infection of hematoma.We retrospectively studied 2639 percutaneous renal biopsies of native kidneys. We compared the clinical characteristics between 2 groups: complication group (gross hematuria and/or perirenal hematoma) and no complication group. The axillary temperature of patients with a hematoma who presented with fever was measured at 06:00, 10:00, 14:00, and 18:00. The onset and duration of fever and the highest body temperature were recorded. Thereafter, we described the time distribution of absorption fever and obtained the curve of fever pattern.Of 2639 patients, PRB complications were observed in 154 (5.8%) patients. Perirenal hematoma was the most common complication, which occurred in 118 (4.5%) of biopsies, including 74 small hematoma cases (thickness ≤3 cm) and 44 large hematoma cases (thickness >3 cm). Major complications were observed in only 6 (0.2%) cases resulting from a large hematoma. Of 118 patients with a perirenal hematoma, absorption fever was observed in 48 cases. Furthermore, large hematomas had a 5.23-fold higher risk for absorption fever than the small ones.Blood pressure, renal insufficiency, and prothrombin time could be risk factors for complications. Fever is common in patients with hematoma because of renal biopsy and is usually noninfectious. Evaluation of patients with post-biopsy fever is necessary to identify any obvious infection sources. If no focus is identified, empiric antibiotic therapy should not be initiated nor should prophylactic antibiotics be extended for prolonged durations. Absorption fevers will resolve in time without specific therapeutic interventions.

    Methods:The newly developed device consists of two parts:the plunger and barrel. On one side, the barrel is bullet shaped with an opening tip. The plunger is located in the middle cavity of the tube barrel and extended out at the open-end. It was designed for strengthening the tube barrel and for convenience in performing the drainage procedure. It can be used by inserting the drainage tube into the lesion and pulling out the plunger, whereby blood will forcefully rise up inside the barrel, providing a satisfactory outcome. It is made for effusion drainage purposes. During the procedure, the drainage tip is placed at the deepest part of the intracranial hematoma to completely drain the blood. Moreover, the plunger fits tightly in the tube, preventing leakage during the operation. With the use of the device, brain can be separated. In addition, the device can help reduce the risk of cerebral damage because of the small operating area. The barrel sidewall has matching opening holes bilaterally and equally for exchanging substances between the inner and outer parts. The overlapping ratio in each horizontal pair is around 1/3–1/2. Each pair on the opposite side will form a different pressure. Thus, the opening holes will not easily get blocked with blood clot. Results: Blood and accumulated liquid from the deepest part of the intracranial hematoma can be directly drawn through the drainage tube without damaging a large area. The tube does not get blocked easily and allows for complete removal of the hematoma. Conclusions:The device is asuitable instrument for clinical application.

    Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the Dengue virus. It is associated with a number of complications, which are well documented. However, Dengue fever associated with rectus sheath hematoma (RSH) is a very rare complication. Only one case report has been published prior supporting the association of Dengue fever with RSH. We report a case of Dengue fever who presented with RSH and was successfully treated conservatively. RSH is also an uncommon cause of acute abdominal pain. It is accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear.

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    Full Text Available The authors report the case of a 50 year-old hypertensive male patient with a pontine hematoma. The clinical presentation was characterized by pure pyramidal deficit signs (no other signs or symptoms were present. A pure hemiplegia syndrome, although common in supratentorial lesions, is considered to be a rare event in pontine vascular lesions. The pathophysiologic mechanisms of these neurological findings are unclear. The exclusive involvement of the pyramidal tract in this case is likely due to a variation in the vascular anatomy of the pons but, in some cases, a vascular malformation may be the cause.

    Cerebral cortical contusions are one of the most common computed tomography findings in head-injured patients and common sequel of traumatic brain injury. These contusions tend to show a progressive increase in mass effect on repeated imaging, most small contusions do not require surgical evacuation. However, progression to subdural hematoma (SDH) in a late aspect is unique. Here we present a 71-year-old man with bifrontal contusion, who deteriorated 43 days after initial trauma with sudden onset of acute SDH. This unusual case suggests that neurosurgeons should be alert for the possibility of very late onset of acute SDH after bifrontal contusions.

    Ten elderly patients (73-87 years, 78.4 years on the average) with subcortical hematomas were divided into two groups according to the shape of the hematoma on a CT scan: a lobulated group (6 patients) and a global group (4 patients). The lobulated group had a history of hypertension in one patient. The hematomas extended widely around the parietal lobe and were accompanied by perifocal edema, brain shifts and subarachnoid hemorrhages, deep consciousness disturbances, and poor prognosis of life and function. Amyloid depositions in the arteries around the hematomas were confirmed histologically in one patient. The global group had a history of hypertension in two patients. The hematomas were localized in the parietal, temporal, or occipital lobe without perifocal edema, brain shift and subarachnoid hemorrhages, and accompanied by mild consciousness disturbances. The life prognosis was good, but the functional prognosis was poor, with a subsequent development of dementia. A lobulated subcortical hematoma is thought to be due to amyloid angiopathy, while a global subcortical hematoma is thought to be due to hypertension. A surgical evacuation is seldom indicated for either type of subcortical hematoma in elderly patients. (author).

    Full Text Available A 15-year-old male high school football player presented with episodes of headache and complete body stiffness, especially in the arms, lower back, and thighs, immediately following a football game. This was accompanied by severe nausea and vomiting for several days. Viral meningitis was suspected by the primary clinician, and treatment with corticosteroids was initiated. Over the next several weeks, there was gradual symptom improvement and the patient returned to his baseline clinical status. The patient experienced a severe recurrence of the previous myriad of symptoms following a subsequent football game, without an obvious isolated traumatic episode. In addition, he experienced a new left sided headache, fatigue, and difficulty ambulating. He was admitted and an extensive workup was performed. CT and MRI of the head revealed concurrent intracranial and spinal subdural hematomas (SDH. Clinical workup did not reveal any evidence of coagulopathy or predisposing vascular lesions. Spinal SDH is an uncommon condition whose concurrence with intracranial SDH is an even greater clinical rarity. We suggest that our case represents an acute on chronic intracranial SDH with rebleeding, membrane rupture, and symptomatic redistribution of hematoma to the spinal subdural space.

    Background Diminishing volume of intracranial cerebrospinal fluid (CSF) in patients with space-occupying masses have been attributed to unfavorable outcome associated with reduction of cerebral perfusion pressure and subsequent brain ischemia. Objective The objective of this article is to employ a ratio of CSF volume to brain volume for longitudinal assessment of space-volume relationships in patients with extra-axial hematoma and to determine variability of the ratio among patients with different types and stages of hematoma. Patients and methods In our retrospective study, we reviewed 113 patients with surgical extra-axial hematomas. We included 28 patients (age 61.7 +/- 17.7 years; 19 males, nine females) with an acute epidural hematoma (EDH) ( n = 5) and subacute/chronic subdural hematoma (SDH) ( n = 23). We excluded 85 patients, in order, due to acute SDH ( n = 76), concurrent intraparenchymal pathology ( n = 6), and bilateral pathology ( n = 3). Noncontrast CT images of the head were obtained using a CT scanner (2004 GE LightSpeed VCT CT system, tube voltage 140 kVp, tube current 310 mA, 5 mm section thickness) preoperatively, postoperatively (3.8 ± 5.8 hours from surgery), and at follow-up clinic visit (48.2 ± 27.7 days after surgery). Each CT scan was loaded into an OsiriX (Pixmeo, Switzerland) workstation to segment pixels based on radiodensity properties measured in Hounsfield units (HU). Based on HU values from -30 to 100, brain, CSF spaces, vascular structures, hematoma, and/or postsurgical fluid were segregated from bony structures, and subsequently hematoma and/or postsurgical fluid were manually selected and removed from the images. The remaining images represented overall brain volume-containing only CSF spaces, vascular structures, and brain parenchyma. Thereafter, the ratio between the total number of voxels representing CSF volume (based on values between 0 and 15 HU) to the total number of voxels

    Full Text Available Sublingual hematoma secondary to anticoagulation is a rare fatal condition. Hemorrhagic complications of warfarin are well-known. This particular case is unique because the patient was on warfarin for the past 2 years but did not develop the sublingual hematoma. However, a trauma by an attrited sharp cusp triggered the episode of the sublingual hematoma in this patient. Being a medical emergency, patient was promptly hospitalized in cardiac care unit and managed by medical team. The patient was transfused with 2 units of fresh frozen plasma and warfarin was temporarily stopped for 4 days. Alternate day regimen of warfarin was started after 4 days, and international normalized ratio dropped to 3. In dental management, enameloplasty of the mandibular first molar tooth was done to prevent trauma and ulcer development in the floor of the mouth. The hematoma resolved, and no new hematoma formation was observed for a period of 6 months.

    Full Text Available Abstract Background To evaluate whether the volume of blood suctioned during vacuum-assisted breast biopsy (VABB is associated with hematoma formation and progression, patient's age and histology of the lesion. Findings 177 women underwent VABB according to standardized protocol. The volume of blood suctioned and hematoma formation were noted at the end of the procedure, as did the subsequent development and progression of hematoma. First- and second-order logistic regression was performed, where appropriate. Cases with hematoma presented with greater volume of blood suctioned (63.8 ± 44.7 cc vs. 17.2 ± 32.9 cc; p Conclusion The likelihood of hematoma is increasing along with increasing amount of blood suctioned, reaching a plateau approximately at 80 cc of blood lost.

    A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC.

    Full Text Available Renal subcapsular hematoma is not an uncommon complication after extracorporeal short wave lithotripsy, trauma, renal angiographic procedures and spontaneously in patients of malignancy and in patients on anticoagulation. We present a patient who developed renal subcapsular hematoma after ureterorenoscopy, which has not been mentioned in literature ever. Clinical spectrum varies from spontaneous resolution through acute renal failure to Page kidney. Page kidney is the external compression of a kidney usually caused by a subcapsular hematoma associated with high blood pressure and occasional renal failure. It is named after Dr. Irvin Page who first demonstrated in 1939 that wrapping cellophane tightly around animal kidneys could cause hypertension. Various management options are mentioned in literature and depend upon the severity of hematoma. Percutaneous drainage is a successful option for the management of subcapsular hematoma in hemodynamic stable patients.

    Full Text Available We describe a case in which a patient with a past medical history of ovarian cancer received a diagnostic renal biopsy for an incidentally discovered renal mass. During left robotic partial nephrectomy (RPN, a perinephric hematoma was encountered. The hematoma was not present on preoperative imaging and was likely a result of the renal biopsy. The renal cell carcinoma (RCC and the associated hematoma were widely excised with negative surgical margins. On follow-up imaging at five months postoperatively, a recurrent renal mass at the surgical resection bed and several new nodules in the omentum were detected. During completion left robotic total nephrectomy and omental excision, intraoperative frozen sections confirmed metastatic RCC. We believe that a hematoma seeded with RCC formed as a result of the renal biopsy, and subsequent disruption of the hematoma during RPN caused contamination of RCC into the surrounding structures.

    Full Text Available Introduction and Objective: Spontaneous pharyngeal-laryngeal hematoma shows the importance of a complete ENT examination in the face of symptoms of banal appearance and a correct history that, in the case reported, unveiled the therapeutic use of anticoagulants. Case description: A 55 year old woman comes to emergency because of unexplained dysphagia. The inspection shows the presence of a hematoma in the pharyngeal-laryngeal region that, after the anticoagulant therapy was reversed, evolved favorably with conservative treatment. Discussion: In this case, apart from medical management performed by the hematology department, we focus our therapeutic approach in the protection of the airway and the prevention of a possible massive bleeding. Determining which patients require endotracheal intubation or tracheostomy and hemostatic surgery is the key to treatment. Conclusions: The anticoagulant therapy involves several complications that ENT specialists must consider in the face of clinical symptoms of dysphagia, dysphonia, dyspnea or signs of bleeding and they must know the possibilities of performance depending on the severity of each case.

    2016-02-01

    We report the first case report of symptomatic bilateral subdural hematomas (SDH) associated with riding a centrifugal motion simulator ride. A previously healthy 55-year-old male developed new onset daily headaches 1 week after going on the ride that were due to symptomatic bilateral SDH requiring operative intervention with a full recovery. There was no history of other trauma or other systemic or intracranial abnormality to account for the development of the SDH. We review the headaches and other clinical features associated with chronic SDH. Twelve cases of roller coaster headaches due to SDH associated with riding roller coasters have been reported. The pathophysiology is reviewed, which we believe is the same mechanism that may be responsible in this case. Although it is possible that this neurovascular injury is truly rare, it is also possible that this injury is underreported as patients and physicians may not make the association or physicians have not reported additional cases. The risk of this injury likely increases with age, as the size of the subdural space increases, and may support the maxim that "roller coasters and simulators are for kids."

    Full Text Available ABSTRACT In the present investigation, the possible effects of the expansion of the Universe on systems bonded either by gravitational or electromagnetic forces, are reconsidered. It will be shown that the acceleration (positive or negative of the expanding background, is the determinant factor affecting planetary orbits and atomic sizes. In the presently accepted cosmology (ΛCDM all bonded systems are expanding at a decreasing rate that tends to be zero as the universe enters in a de Sitter phase. It is worth mentioning that the estimated expansion rates are rather small and they can be neglected for all practical purposes.

    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.

    2016-01-01

    Full Text Available Background. Large craniotomy for acute subdural hematoma is sometimes too invasive. We report good outcomes for two cases of neuroendoscopic evacuation of hematoma and contusion by 1 burr hole surgery. Case Presentation. Both patients arrived by ambulance at our hospital with disturbed consciousness after falling. Case 1 was an 81-year-old man who took antiplatelet drugs for brain infarction. Case 2 was a 73-year-old alcoholic woman. CT scanning showed acute subdural hematoma and frontal contusion in both cases. In the acute stage, glycerol was administered to reduce edema; CTs after 48 and 72 hours showed an increase of subdural hematoma and massive contusion of the frontal lobe. Disturbed consciousness steadily deteriorated. The subdural hematoma and contusion were removed as soon as possible by neuroendoscopy under local anesthesia, because neither patient was a good candidate for large craniotomy considering age and past history. 40%~70% of the hematoma was removed, and the consciousness level improved. Conclusion. Neuroendoscopic removal of acute subdural hematoma and contusion has advantages and disadvantages. For patients with underlying medical issues or other risk factors, it is likely to be effective.

    OBJECTIVE There is little information on the frequency of symptomatic epidural hematomas after the implantation of paddle spinal cord stimulators (SCSs) in the thoracic spine. The purpose of this paper is to provide this metric and compare it to the frequency of symptomatic epidural hematomas for all other thoracic laminectomies combined. METHODS This study involved retrospectively analyzing the experience of a single surgeon in a consecutive series of patients who underwent the implantation of a thoracic paddle SCS with respect to the occurrence of a symptomatic epidural hematoma. For comparison, the occurrence of a symptomatic epidural hematoma in non-SCS thoracic laminectomies done during the same period of time was determined. RESULTS One hundred fifty-four thoracic paddle SCSs were implanted between May 2002 and February 2015. Despite perfect hemostasis and no preoperative risk factors, 4 of 154 patients (2.60%) developed postoperative lower-extremity weakness caused by an epidural hematoma. There were no other causes of a neurological deficit. In 3 of the 4 patients, the symptoms were delayed. Over the same time period, only 1 of 119 patients (0.84%) developed a postoperative motor deficit from a symptomatic epidural hematoma after a non-SCS laminectomy. CONCLUSIONS The occurrence of epidural hematomas after thoracic paddle SCS implantation may be underreported. Suggestions are given to decrease its incidence. It seems paradoxical that an epidural hematoma occurred 3 times more often after small SCS thoracic laminectomies than after larger non-SCS thoracic laminectomies. If confirmed by future studies, this finding may suggest that the intrusion of instruments into a confined epidural sublaminar space or the presence of a paddle and a hematoma in this restricted space may account for this differential.

    Full Text Available The surgical option to evacuate an intracranial extradural hematoma (EDH was postponed in a 2-year-old female child who appeared fully alert and active after a brief spell of unconsciousness following a fall from height. The child was received, with a swelling on and around the right parietal eminence, by the emergency staff just half an hour after the time of injury. The immediate X-ray skull and first computed tomography (CT scan head showed a parietal bone fracture, EDH, and cephalhematoma. However, follow-up CT scan head after about 4΍ h revealed the dramatic absence of EDH but increased size and bogginess of cephalhematoma. The EDH had transported into subgaleal space resulting in a decompression of intracranial compartment in <5 h, thereby preventing surgical intervention but necessitating monitoring, though there was no back flow intracranially.

    An 86-year-old woman was scheduled to undergo aortic valve replacement and coronary artery bypass graft. On postoperative day 3, she developed sudden-onset neck pain followed by weakness in the right arm. Her symptoms worsened with time, and she developed paraplegia. At 60 h after the first complaint, spontaneous spinal epidural hematoma (SSEH) from C2 to C6 with spinal cord compression was diagnosed from a magnetic resonance image of the cervical region. We decided on conservative therapy because operative recovery was impossible. Delayed diagnosis led to grievous results in the present case. When neurological abnormalities follow neck or back pain after open heart surgery, SSEH must be considered in the differential diagnosis. Further, if it is suspected, early cervical computed tomography/magnetic resonance imaging and surgery should be considered.

    A woman, aged 84 years, presented to our emergency department with posteriorly radiating chest pain that began following dinner. She reported no change in bowel habits, hematochezia, or melena. She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

    Foreign accent syndrome (FAS), a rare disorder characterized by the emergence of a new accent perceived as foreign by listeners, is usually reported with left brain damage. We here report the case of a 28-year-old native Brazilian who appeared, to the examiner, to show a North American accent during recovery from Broca's aphasia. The lesion was due to a frontal hematoma. Without referring specifically to speech, we asked 10 independent observers to comment on a videotape of the patient's interview. Seven reported that the patient had a foreign accent, while 3 simply noted a 'strange' accent. The observers did not agree on the origin of the accent, 5 identifying it as Spanish, 1 as German, and 1 as south Brazilian. These findings suggest that FAS is not due to the acquisition of a specific foreign accent, but to impairment of the suprasegmental linguistic abilities (tone, accent, pauses, rhythm, and vocal stress) that make it possible to distinguish native language.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    Full Text Available Neonatal scrotal hematoma is a rare genitourinary emergency. Some cases have underlining aetiologic factors such as testicular torsion, adrenal hemorrhage, or birth trauma, and others are idiopathic. Previously, immediate scrotal exploration was considered imperative for diagnosis and treatment. With good imaging techniques, some patients are managed nonoperatively. We report a case of idiopathic scrotal hematoma in a neonate. He was managed conservatively with clinical and radiological follow-up. There was complete resolution of hematoma within two months, thus, avoiding unnecessary exploration.

    We describe a case involving spontaneous retroperitoneal hematoma complicating a normal delivery in a context of a Disseminated Intravascular Coagulation (DIVC) at the end of the pregnancy. Given the defaced symptomatology, an abdomino-pelvic scanner and an examination with a general anaesthesia made it possible to diagnose and to monitor the hematoma in intensive care. The correction of the hemostasis troubles and of the anemia, without another invasive intervention, allowed a return to home at the eighth day. The pathophysiological mechanisms underlying development and practicable treatments of this post-partum hematoma are discussed.

    Epidural hematoma is a rare cause of spinal cord compression, which usually provokes severe neurological deficits. It is presumed to originate from venous or, more probably, arterial bleeding. Thrombocytopenia and other disorders of coagulation may precipitate the onset of epidural hematoma and facilitate the evolution of the disease. We report the case of a patient suffering from a non-Hodgkin's lymphoma with severe thrombocytopenia during a MACOP-B schedule, who presented with a spontaneous cervical epidural hematoma. We discuss the etiopathological aspects, diagnosis, and treatment of this rare cause of acute cervical spinal cord compression.

However, urinary tract infection (UTI has not been reported in association with this condition. We report on a 4-week old child with massive unilateral adrenal hematoma discovered incidentally during a routine abdominal ultrasound scan for UTI. The mass resolved spontaneously after several months with no complications. The diagnosis and ma-nagement of infantile suprarenal mass and the possible link between this child′s UTI and the adrenal hematoma are discussed.

    2010-01-01

    From July 2003 to July 2009, 15 cases of subdural hematoma with swirl signs were treated in our hospital and their clinical data were retrospectively analysed.The mortality was compared between these patients and those with typical acute subdural hematoma who were treated at the same time in our hospital. Among the 15 cases, full recovery was achieved in 4 cases, slight disability in 2, gave disability in 2 and death in 7 (46.7%). The mortality of these patients was conspicuously higher than that of typical subdural hematoma (14/83, 16.9%, P<0.01). Subdural hematoma with swirl signs is often suggestive of hazardous pathogenetic condition and early diagnosis and prompt surgical intervention is essential to reduce mortality.

    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 lfuids;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 signiifcantly slower hematoma absorption rate, and signiifcantly increased National Institutes of Health Stroke Scale scores and modiifed Rankin Scale scores. These results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.

  19. Alcohol Abuse and Alcoholic Liver Cirrhosis Leading to Spontaneous Muscle Hematoma: An Event Fraught with Danger

    2015-04-01

    Full Text Available Alcohol abuse is associated with both potentiating and antagonizing hemostatic states. Liver cirrhosis is an independent causal factor for many bleeding complications. The long-term effects of alcohol abuse coupled with advanced liver cirrhosis are additive in favor of bleeding. We report the case of a patient with a history of alcohol abuse who presented with liver cirrhosis and nontraumatic muscle hematoma diagnosed as a spontaneous hematoma of the gastrocnemius muscle. He was managed conservatively with infusions of fresh frozen plasma and platelets, which resulted in resolution of the hematoma. The pathogenesis of ‘spontaneous' muscle hematoma remains anecdotal, but since it is reported in patients on anticoagulant therapy or with hemostatic disorders, it is hypothetically related to severely deranged coagulation. Here we review the relevant literature pertaining to the pathogenesis, presentation and treatment options available for treating this often fatal complication of bleeding diatheses.

    Full Text Available Traumatic retroclival hematomas are uncommon lesions usually associated with significant trauma. Majority of the reported hematomas are epidural; and in the pediatric population. Retroclival acute subdural hematomas (RSDH are very rare, with only two previous cases reported in English literature. An 18-year-old man presented with headache and no deficits following an accident. Computer tomography (CT scan and magnetic resonance imaging (MRI showed an acute RSDH extending into the spinal subdural space. He developed bilateral sixth nerve palsies, with symptoms of raised intracranial pressure within the next 24 hours. He underwent evacuation of hematoma with a good outcome. Another 19-year-old man presented with neck pain following a fall from a moving bus. He had no neurological deficits. CT scan showed a RSDH extending across the craniovertebral junction. He was managed conservatively with good outcome.

  1. Endoscopic removal of subgaleal hematoma in a 7-year-old patient treated with anticoagulant and antiplatelet agents

    Yasuhiko Hayashi

    2014-01-01

    Full Text Available Background: Subgaleal hematomas frequently occur in children after head trauma and extend over the cranial sutures. Although conservative treatment suffices in most cases, surgical removal of a subgaleal hematoma is indicated when the patient presents with anemia and headache associated with its progressive enlargement. Case Description: We present the case of a 7-year-old boy who was medicated with warfarin and aspirin due to a hypoplastic left ventricle and fell from a rock wherein he hit his head in the frontal region. Although a computed tomography scan of the head revealed no intracranial lesion, an extracranial hematoma was found to extend over the cranial sutures, leading to the diagnosis of subgaleal hematoma. The hematoma continued to grow gradually despite the cessation of warfarin and aspirin therapy immediately after the head trauma. Since the patient′s headache and anemia were progressing as the hematoma enlarged, removal of the hematoma was performed 3 days after admission. Endoscopic hematoma removal was planned to enable accurate coagulation of the sites of bleeding and removal of the maximal amount of hematoma through minimal incision. The hematoma was completely removed, and the patient′s postoperative course was excellent with alleviation of both the anemia and the headache. No sign of hematoma recurrence could be detected during 2 years follow-up. Conclusion: An angled endoscope can allow visualization of the deep subgaleal space, and this technique enabled direct visualization of the bleeding sites and accurate coagulation to prevent recurrence of hematoma. Endoscopic techniques, such as minimally invasive techniques, can allow sufficient removal of subgaleal hematoma with minimal morbidity, especially in patients such as ours.

    A newborn presented on day 15 of life with an epidural hematoma, extending through a diastatic sutura squamosa in an external cephalhematoma. There was no skull fracture. The cephalhematoma was punctured twice with 24-h interval, reducing both the cephalhematoma and the epidural component. In the absence of neurological signs or symptoms, aspirating a cephalhematoma to evacuate the communicating epidural hematoma in a newborn infant may avoid more invasive surgical intervention.

    Objective To study the effect of endoscopic-assisted keyhole operation (EAKO) on treating hypertensive intracranial hematomas and the value of our patent dissector appli ed during the operation.Methods A total of 25 patients with hypertensive intracranial hematomas underwent endos copic-assisted keyhole evacuation, during which, the viewing dissector, which h ad recently achieved national patent, was connected to the tip of endoscope and used to help dissect hematomas. The outcome of this procedure were compared wit h those of 22 comparable cases undergone conventional surgical treatment (large or smaller craniotomy). The items for comparison included the volum e of remaining hematoma, the duration of operation, postsurgical Glasgow Coma Sc ale (GCS) and Glasgow Outcome Scale (GOS).Results Remaining hematoma was ascertained 48 h after operation with the use of computerized tomography (CT) scans. In the case of EAKO, nearly complete evacuation (>84%) was achieved in 21 cases; GCS was evaluated at 7 d postsurgery result ing in GCS >12 in 9 patients, GCS 9-12 in 12 patients and GCS <9 in 4 patients. The follow-up period ranged from 6 to 21 mon. GOS was estimated at half a year and good recovery rate as defined by GOS was assigned to 76% of the EAKO pa tients. There are significant differences in the volumes of remaining hematomas and the duration of operation between the EAKO and craniotomy group (P<0.0 5). In addition, better clinical outcomes were obtained in EAKO. Conclusion EAKO has the advantage of being minimally invasive, improving surgical results and the prognosis of hypertensive intracranial hematoma patients. We conclude th at keyhole operation is a safe, effective alternative for removal of hypertensiv e intracranial hematoma, particularly during acute stages.

    Full Text Available Paget′s disease of skull usually causes neurological complications such as basilar invagination, cranial neuropathies, etc. Occurrence of extradural hematoma in association with Paget′s disease of skull is rare. A 48 year old man presented with headache and right upper limb weakness, two days after a fall from scooter. CT Scan of brain showed a large extradural hematoma at the vertex with the cranial vault showing features of Paget′s disease. At surgery, no skull fracture or injury to the superior sagittal sinus was evident. There was diffuse oozing from the inner table of the skull, which showed features of Paget′s disease. The extradural hematoma was evacuated and the patient made good recovery.He deteriorated a few hours after surgery. Follow up CT Scan showed diffuse brain swelling with minimal recollection of hematoma. Re-exploration showed a small recollection which was evacuated and the part of the oozing diseased skull was excised. The patient recovered completely. This is the first reported case of vertex extradural hematoma in association with the Paget′s disease of skull. The unusual features are the absence of skull fracture and injury to the superior sagittal sinus. The increased vascularity of the skull due to Paget′s disease has caused the hematoma by diffuse oozing from the inner table.

    Full Text Available Abstract Background Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. Case presentation A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient’s left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Conclusion Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

Iran J Child Neurol. 2013  Spring;7(2:47-50.Abstract Spontaneous ventral spinal epidural hematomas are extremely rare in children and clinically recognized by the appearance of acute asymmetric focal motor and sensory involvement. In infants, the initial presenting symptoms are very non-specific and irritability is often the only initial manifestation. Appearance of other neurological signs may be delayed up to hours or even days later. In the absence of significant precipitating factors such as severe trauma or previously known coagulopathies,the diagnosis is usually delayed until the full picture of severe cord compression is developed. The diagnosis is finally made by performing magnetic resonance imaging. We report a 5-month-old infant with spinal epidural hematoma who presented with symmetrical upper limb weakness and diaphragmatic involvement to highlight the importance of recognizing the atypical manifestations for early diagnosis andintervention. References:1.

    A non-invasive microwave device for the detection of epi/subdural hemorrhaging (hematoma) is under current development. The final device will be highly portable and allow real time assessment of head injuries, thereby satisfying early detection needs of the field technician as well as providing a tool for repetitious monitoring of high-risk individuals. The device will adopt the advanced technology of micropower impulse radar (MIR) which is a state of the art low cost ultra wide band (UWB) microwave radar developed here at LLNL. It will consist of a MIR transmitting and receiving module, a computer based signal processing module, and a device-to-patient signal coupling module--the UWB antenna. The prototype design is being guided by the needs of the patient and the practitioner along with the prerequisites of the technology including issues such as the specificity of the device, efficacy of diagnosis, accuracy, robustness, and patient comfort. The prototype development follows a concurrent approach which .includes experiments designed to evaluate requirements of the radar and antenna design, phantom development to facilitate laboratory investigations, and investigation into the limits of adapting pre-existing non-medical MIR devices to medical applications. This report will present the accomplishments and project highlights to date in the fiscal year 1999. Future project projections will also be discussed.

    Full Text Available INTRODUCTION: Head trauma is an important consequence of child abuse. Specific pathophysiological mechanisms in child abuse are responsible for the ''whiplash shaken-baby syndrome'', which would favour the occurrence of intracranial hemorrhages. CASE REPORT: We report the case of a child who developed epidural hematoma following minor-intensity head trauma. Initial diagnosis of child abuse was made, but subsequent investigation led to the diagnosis of hemophilia A. CONCLUSION: Even though epidural hematoma is not closely associated with child abuse, this aethiology must always be considered when the reported trauma mechanism is out of proportion to the magnitude of the encountered lesions.INTRODUÇÃO: Traumatismo crânio-encefálico é importante conseqüência de abuso infantil. Mecanismos fisiopatológicos específicos do abuso infantil são responsáveis pela ''whiplash shaken-baby syndrome'', o que favoreceria o aparecimento de hemorragias intracranianas. RELATO DE CASO: Relatamos o caso de uma criança que desenvolveu hematoma extradural após trauma de pequena intensidade. Foi feito diagnóstico inicial de abuso infantil, mas investigações subseqüentes levaram ao diagnóstico de hemofilia A. CONCLUSÃO: Embora o hematoma extradural não esteja intimamente relacionado com abuso infantil, esta etiologia deve ser sempre considerada quando o mecanismo de trauma relatado estiver fora de proporção com as lesões encontradas.

    Impact trauma may cause a hematoma, which is the leakage of venous blood into surrounding tissues. Large hematomas can be dangerous as they may inhibit local blood ow. Hematomas are often diagnosed visually, which may be problematic if the hematoma leaks deeper than the visible penetration depth. Furthermore, vascular wound healing is often monitored at home without the aid of a clinician. We therefore investigated the use of near infrared (NIR) re ectance photoplethysmographic imaging (PPGI) to assess vascular damage resulting from a hematoma, and monitor the healing process. In this case study, the participant experienced internal vascular damage in the form of a hematoma. Using a PPGI system with dual-mode temporally coded illumination for ambient-agnostic data acquisition and mounted optical elements, the tissue was illuminated with a spatially uniform irradiance pattern of 850 nm wavelength light for increased tissue penetration and high oxy-to-deoxyhemoglobin absorption ratio. Initial and follow-up PPGI data collection was performed to assess vascular damage and healing. The tissue PPGI sequences were spectrally analyzed, producing spectral maps of the tissue area. Experimental results show that spatial differences in spectral information can be observed around the damaged area. In particular, the damaged site exhibited lower pulsatility than the surrounding healthy tissue. This pulsatility was largely restored in the follow-up data, suggesting that the tissue had undergone vascular healing. These results indicate that hematomas can be assessed and monitored in a non-contact visual manner, and suggests that PPGI can be used for tissue health assessment, with potential extensions to peripheral vascular disease.

    The paper has a threefold purpose. The first purpose is to present an explicit description of expanded cyclic codes defined in $\\GF(q^m)$. The proposed explicit construction of expanded generator matrix and expanded parity check matrix maintains the symbol-wise algebraic structure and thus keeps many important original characteristics. The second purpose of this paper is to identify a class of constant-weight cyclic codes. Specifically, we show that a well-known class of $q$-ary BCH codes excluding the all-zero codeword are constant-weight cyclic codes. Moreover, we show this class of codes achieve the Plotkin bound. The last purpose of the paper is to characterize expanded cyclic codes utilizing the proposed expanded generator matrix and parity check matrix. We analyze the properties of component codewords of a codeword and particularly establish the precise conditions under which a codeword can be represented by a subbasis. With the new insights, we present an improved lower bound on the minimum distance of...

    Full Text Available CONTEXT: Although endoscopic esophageal variceal sclerotherapy has been largely supplanted by variceal band ligation, it is still performed routinely in many institutions, especially in developing countries. Intramural esophageal hematoma has been described as a rare complication of sclerotherapy. Risk factors have not been completely established. OBJECTIVE: To demonstrate the incidence of post-sclerotherapy intramural esophageal hematoma in our hospital and discuss the possible factors involved. Methods - This is a retrospective observational study made at the "Hospital Universitário Clementino Fraga Filho", Rio de Janeiro, RJ, Brazil, reviewing the medical records of all esophageal variceal sclerotherapy procedures performed from April 2000 to November 2005. The evaluation of the clinical, laboratorial and endoscopic features in our patients and those reported in the literature was also done. Review of literature was performed through MEDLINE search. RESULTS: A total of 1,433 esophageal variceal sclerotherapy procedures were performed in 397 patients, with an intramural esophageal hematoma incidence of 4 cases (0.28%. Three of our patients developed additional complications, and one death was a direct consequence of a rupture of the hematoma. Nineteen well described cases were reported in the literature. Intramural esophageal hematoma occurred mostly after the forth esophageal variceal sclerotherapy session. Coagulation disturbances were present in the majority of cases. CONCLUSION: Intramural esophageal hematoma is a rare complication of esophageal variceal sclerotherapy and its incidence in our institution was similar to those observed in the literature. Our study suggests that this complication occurs as a result of a fragile esophageal mucosa after previous esophageal variceal sclerotherapy sessions. Impaired coagulation, although not essential, could contribute to hematoma formation and extension through esophageal submucosa

    Full Text Available Mediastinal hematoma is a rare complication following insertion of a central venous catheter with only few cases reported in the English literature. We report a case of a 71-year-old female who was admitted for elective chemoport placement. USG guided right internal jugular access was attempted using the Seldinger technique. Resistance was met while threading the guidewire. USG showed a chronic clot burden in the RIJ. A microvascular access was established under fluoroscopic guidance. Rest of the procedure was completed without any further issues. Following extubation, the patient complained of right-sided chest pain radiating to the back. Chest X-ray revealed a contained white out in the right upper lung field. She became hemodynamically unstable. Repeated X-ray showed progression of the hematoma. Median Sternotomy showed posterior mediastinal hematoma tracking into right pleural cavity. Active bleeding from the puncture site at RIJ-SCL junction was repaired. Patient had an uneventful recovery. Injury to the central venous system is the result of either penetrating trauma or iatrogenic causes as in our case. A possible explanation of our complication may be attributed to the forced manipulation of the dilator or guidewire against resistance. Clavicle and sternum offer bony protection to the underlying vital venous structures and injuries often need sternotomy with or without neck extension. Division of the clavicle and disarticulation of the sternoclavicular joint may be required for optimum exposure. Meticulous surgical technique, knowledge of the possible complications, and close monitoring in the postprocedural period are of utmost importance. Chest X-ray showed to be routinely done to detect any complication early.

    A rare case of acute epidural hematoma of the posterior fossa associated with von Willebrand's disease is reported. A 9-year-old boy fell down and hit his occipital region against a floor. Soon after he came home and slept, but three hours later he began to vomit and became drowsiness. He visited our hospital and his Glasgow Coma Scale showed 13 points. CT scan on admission showed acute epidural hematoma of left posterior fossa and contusional hematoma in the right temporal lobe. The bleeding time was over 18 minutes. He had been suspected to be suffering from von Willebrand's disease two years ago. Then fresh blood, fresh frozen plasma and anti-hemophilic globulin were prepared. Ten hours after injury, the operation was begun. Fresh epidural hematoma existed as a clot beyond transverse sinus. During the procedure of dural tenting suture, diffuse bleeding from bone, muscle, subcutaneous tissue and dura occurred and it was difficult to stop the bleeding. By using fresh blood and anti-hemophilic globulin, the bleeding was controlled, and then the operation was achieved. In the postoperative course a new epidural hematoma was found in the left temporal region and a new but asymptomatic retinal hemorrhage was found in his right eye. He was discharged without any neurological deficits 25 days after operation.

    Full Text Available Abstract Introduction Postoperative spinal extradural hematomas are rare. Most of the cases that have been reported occured within 3 days of surgery. Their occurrence in a delayed form, that is, more than 72 hours after surgery, is very rare. This case is being reported to enhance awareness of delayed postoperative spinal extradural hematomas. Case presentation We report a case of acute onset dorsal spinal extradural hematoma from a paraspinal muscular arterial bleed, producing paraplegia 72 hours following surgery for excision of a spinal cord tumor at T8 level. The triggering mechanism was an episode of violent twisting movement by the patient. Fresh blood in the postoperative drain tube provided suspicion of this complication. Emergency evacuation of the clot helped in regaining normal motor and sensory function. The need to avoid straining of the paraspinal muscles in the postoperative period is emphasized. Conclusion Most cases of postoperative spinal extradural hematomas occur as a result of venous bleeding. However, an arterial source of bleeding from paraspinal muscular branches causing extradural hematoma and subsequent neurological deficit is underreported. Undue straining of paraspinal muscles in the postoperative period after major spinal surgery should be avoided for at least a few days.

    Total hip arthroplasty is a prevalent orthopedic intervention in the United States. Massive postoperative hematomas are a rare albeit serious complication of the procedure. Sequelae of these hematomas can include lower extremity paralysis from compression of the sciatic nerve. A 66-year-old woman taking aspirin and clopidogrel for coronary stents presented with a complete foot drop, paresthesias, and lower extremity pain 10 days after a total hip arthroplasty. The patient was initially seen by a neurology service at another hospital and thought to have lateral recess stenosis. At the authors' center, magnetic resonance imaging of the lumbar spine failed to show lateral recess stenosis. Urgent pelvic computed tomography showed a large hematoma and raised suspicion of sciatic nerve compression. Hip magnetic resonance imaging showed a right gluteal hematoma compressing the sciatic nerve. The patient was then taken to the operating room for the clot to be evacuated and was later referred for rehabilitation. Massive hematomas after total hip arthroplasty are an important consideration in the differential diagnosis of nontraumatic acute foot drop. Prompt diagnosis may correlate with improved neurological outcome and help reduce overall morbidity.

    Hematoma of the cervical ligamentum flavum is very rare, and its pathogenesis is unknown. We describe a case of ligamentum flavum hematoma in the cervical spine causing severe myelopathy. Postoperative histological examination suggested it was the result of the rupture of a hemangioma or of an arteriovenous malformation in the ligamentum flavum. After removal of the lesion, the patient's condition immediately improved. Review of all three reported cases, including this one, showed that complete resection of the mass resulted in immediate relief of symptoms of incomplete paraplegia. The findings of magnetic resonance imaging (MRI) of the hematoma may vary with time, and they may show no characteristic intensity. However, MRI of this case revealed that the tissues surrounding the mass were enhanced with gadolinium diethylene triamine penta-acetic acid, and an area of homogeneous iso-intensity was clearly surrounded by a low-intensity area (flavum) on T2-weighed short-tau inversion recovery images. These findings could be characteristic of the ligamentum flavum hematoma and might help in the differentiation from a cervical epidural hematoma. (orig.)

  7. Lateral abdominal wall hematoma as a rare complication after carotid artery stenting: a case report

    Full Text Available Abstract Abdominal wall hematoma is a rare and life-threatening complication after carotid artery stenting (CAS, but it can occur when activated clotting time is prolonged. We report a right lateral abdominal wall hematoma caused by rupture of the superficial circumflex iliac artery after CAS in a 72-year-old man with severe stenosis of the origin of the right internal carotid artery. We performed CAS for the targeted lesion while activated clotting time exceeded 300 seconds. After 2 hours, he complained of right lateral abdominal pain. Abdominal computed tomography revealed an extensive hematoma in the right lateral abdominal wall. Activated clotting time was 180 seconds at this point. Seven hours later, he developed hypotension and hemoglobin level dropped to 11.3 g/dl. Subsequent computed tomography showed enlargement of the hematoma. Emergent selective angiography of the external iliac artery revealed active bleeding from the right superficial circumflex iliac artery. Transcatheter arterial embolization with Gelfoam and microcoils was performed successfully. With more CAS procedures being performed, it is important for endovascular surgeons and radiologists to consider the possibility of abdominal wall hematoma in this situation.

    Full Text Available Introduction: Acute traumatic subdural hematoma (ASDH is one of the most frequent conditions in neurosurgery demanding emergency surgery. The aim of the study was to identify factors influencing outcome in patients who had surgery for evacuation of ASDH. Methods: From 2005 to 2012 eighty-five patients at age above 18 years had surgery for evacuation of ASDH. Outcome was measured according GOS at discharge and was dichotomized as “favorable outcome” (GOS 4 to 5 and “unfavorable outcome” (GOS 1 to 3. These factors were evaluated with univariate and logistic regression analysis for significance with outcome. Results: The mean age of the 85 patients was 62.7 years (SD±18.5. 45.9% patients were with favorable outcome and 54.1% had unfavorable outcome. Patients with GCS score 3-8 (54.1% had 80.4% unfavorable outcome whereas 78.6% of patients with GCS score 13-15 (32.9% had favorable outcome. All patients with nonreactive pupils (bilaterally or unilaterally - 31.8% had unfavorable outcome whereas patients (36.5% with both reactive pupils (36.5% had in 80.6% favorable outcome. All patients (40% with Rotterdam CT scores 5 and 6 had unfavorable outcome. The factors determining outcome were admission GSC score, Rotterdam CT scores, and prothrombin time. Conclusion: Patients who have GSC score of 3, unresponsive pupil(s or have Rotterdam CT scores 5 and 6 have little chance of survival. Patients with coagulopathy have two times more unfavorable outcome. The patients with ASDH should have surgery as soon as possible after correction of vital parameters in order to avoid deterioration which can be very rapid and irreversible.

    2009-01-01

    Full Text Available We report a 57-year-old man who presented one month after sustaining a traumatic right temporal intracerebral hematoma with history of headache, left hemiparesis and altered sensorium of two days duration. A diagnosis of right temporal resolving hematoma was made on computed tomography scan. However, his sensorium progressively deteriorated and he underwent craniotomy and partial excision of an abscess. He was treated with appropriate antibiotics for six weeks despite of which he did not improve and died nine months later. We conclude that there should be a high index of suspicion for brain abscess in patients with traumatic intracerebral hemorrhage if the clinical and radiological picture is different from the expected course of a resolving hematoma.

    We present the first report of an intraventricular encapsulated hematoma, mimicking cavernous malformation on imaging and gross lesion appearance. A 47-year-old female on anticoagulation therapy for atrial fibrillation presented with left upper extremity apraxia, neglect, and mild gait imbalance. Her brain CT scan and MRI revealed multilobulated lesions involving the choroid plexus in the atria of both lateral ventricles. The intraoperative appearance was that of encapsulated mass, with blood clots at different stages of liquefaction and organization, all consistent with the gross appearance of a cavernous malformation. However, histopathologic examination demonstrated hematoma with components at different ages, and normal vessel infiltration without any hint of cavernous malformation histology, or underlying neoplasia. Encapsulated hematoma should be considered in the differential diagnosis of hemorrhagic intraventricular masses. PMID:21435884

    Full Text Available Femoral nerve neuropathy after total hip arthroplasty is rare but catastrophic complication. Pain and quadriceps muscle weakness caused by this complication can significantly affect the functional outcome. Here we present a case report, describing delayed onset femoral nerve palsy associated with iliopsoas hematoma following pseudoaneurysm of a branch of profunda femoris artery after 3 months of primary total hip arthroplasty in an 80-year-old female patient with single kidney. Hip arthroplasty was done for painful primary osteoarthritis of left hip. Diagnosis of femoral nerve palsy was made by clinical examination and computed tomography imaging of pelvis. Patient was managed by surgical evacuation of hematoma and physiotherapy. The patient’s clinical symptoms were improved after surgical evacuation of hematoma. This is the first case report of its kind in English literature regarding delayed onset femoral nerve palsy after primary total hip arthroplasty due to pseudoaneurysm of a branch of profunda femoris artery without any obvious precipitating factor.

  16. The hematoma block: a simple, effective technique for closed reduction of ankle fracture dislocations.

    2011-01-01

    Management of a dislocated ankle fracture can be challenging because of instability of the ankle mortise, a compromised soft tissue envelope, and the potential neurovascular compromise. Every effort should be made to quickly and efficiently relocate the disrupted ankle joint. Within the emergency department setting, narcotics and benzodiazepines can be used to sedate the patient before attempting closed reduction. The combination of narcotics and benzodiazepines provides relief of pain and muscle guarding; however, it conveys a risk of seizure as well as respiratory arrest. An alternative to conscious sedation is the hematoma block, or an intra-articular local anesthetic injection in the ankle joint and the associated fracture hematoma. The hematoma block offers a comparable amount of analgesia to conscious sedation without the additional cardiovascular risk, hospital cost, and procedure time.

  18. Want to operate an abdominal lump? Think twice; it might be spontaneous rectus sheath hematoma: a case report

    Directory of Open Access Journals (Sweden)

    Manisha Sarkar

    2016-09-01

    Full Text Available Rectus sheath hematoma is a rare, but potentially misdiagnosed clinical entity. It occurs when there is direct tear in the rectus abdominis muscle fibres or in the supplying blood vessels. It may be associated with trauma, raised intra-abdominal pressure, or muscle weakness. When non-traumatic, the condition is termed as spontaneous rectus sheath hematoma. Because of its rarity, spontaneous rectus hematoma can be easily missed, endangering patient management. With progressively increasing use of anticoagulant and antiplatelet agents, the incidence of this pathology is rising. We are reporting a case of spontaneous rectus sheath hematoma in a 56 year old female, known diabetic, hypertensive with dyslipidaemia on combination drug therapy but not on anticoagulant/antiplatelet medications, that was clinically misdiagnosed as omental hernia. The main presenting complaint was swelling in abdomen for 1 month. There was no history of trauma. Radiologic findings showed hypoechoic multiloculated complex cystic lesion. Cytological findings showed features of old hematoma. This case report intends to increase awareness in considering rectus sheath hematoma as an important differential diagnosis of lump abdomen. Rectus sheath hematoma, a rarely seen pathology, often confuses clinicians leading to unnecessary negative laparotomies. Definitive operative procedure should not be undertaken depending on sonographic findings alone, as the images are prone to subjective error. The main treatment modality of rectus sheath hematoma is conservative management. [Int J Res Med Sci 2016; 4(9.000: 4208-4211

    A 38-year-old man who had been treated with warfarin since mitral valve replacement 10 years earlier presented with acute onset of epigastralgia and melena. Coagulation tests were abnormal with a prolonged prothrombin time of >60 seconds and a prolonged activated partial thromboplastin time of >120 seconds. Abdominal sonographic examination revealed duodenal intramural hematoma that was confirmed on CT. Warfarin therapy was stopped and the patient was treated conservatively with vitamin K and fresh frozen plasma. Recovery was uneventful, and the patient was re-warfarinized 2 weeks later. Duodenal hematoma can be readily diagnosed with bedside sonography.

    Full Text Available A 77-year-old man suffered hypoxemic cardiac arrest by supraglottic and tracheal airway obstruction in the emergency department. A previously unknown cervical fracture had caused a traumatic retropharyngeal-mediastinal hematoma. A lifesaving surgical emergency tracheostomy succeeded. Supraglottic and tracheal obstruction by a retropharyngeal-mediastinal hematoma with successful resuscitation via emergency tracheostomy after hypoxemic cardiac arrest has never been reported in a context of trauma. This clinically demanding case outlines the need for multidisciplinary airway management systems with continuous training and well-implemented guidelines.

    Full Text Available Although uncommon, blunt trauma to the perineum may cause serious injury to the penis. Differentiation between penile fracture with torn tunica albuginea versus extratunical or cavernosal hematomas is crucial because the former condition needs early surgical repair to avoid future deformity and erectile dysfunction, whereas approach is conservative with even large penoscrotal hematomas with albugineal integrity. Urgent-setting magnetic resonance imaging including multiplanar images of the injured penoscrotal region allows precise identification or exclusion of presence, site, and extent of tears of the tunica albuginea, providing a consistent basis for therapeutic choice.

    Reports about neurological injury related to roller-coaster rides mostly involve adults; we present a case of subdural hematoma in a pediatric patient presented 14 days after a roller-coaster ride. These rides show extreme up-and-down, to-and-fro, and rotatory acceleration/deceleration forces that could produce tensile and shearing stresses with tearing of bridging cerebral veins resulting in subdural hemorrhage. Pediatricians should consider roller-coaster riding a modern cause of subdural hematoma, as well as a possible cause of unexplained neurologic events in otherwise healthy adolescents.

    Acute aortic syndromes, encompassing intramural hematoma, penetrating ulcer, and pseudoaneurysm, are best demonstrated by angiographic CT and magnetic resonance imaging. These imaging modalities provide an accurate evaluation and allow timely therapies of these frequently symptomatic lesions, thus reducing their morbidity and mortality. The inflammatory pathogenesis of these acute aortic syndromes may exhibit positive PET findings predictive of prognosis and outcomes of these vascular events. The authors present a case of PET/CT imaging showing asymptomatic intramural hematomas with penetrating ulcer and saccular pseudoaneurysm of the proximal abdominal aorta.

    Subperiosteal hematoma of the orbit is a rare disease and most of the cases occur in young adult males as a result of direct facial or orbital trauma. In the absence of direct facial or orbital trauma, nontranmatic subperiosteal orbital hematoma has rarely been reported in association with a sudden elevation of cranial venous pressure or venous congestion, systemic diseases associated with a bleeding diathesis and paranasal sinusitis. We report here on a rare case of subperiosteal orbital hemaboma associated with ethmoid sinusitis, as was seen on CT imaging.

    Whiplash Associated Disorders (WAD) has been reported as an adult phenomenon. Whiplash injury has classically been described as a cervical soft tissue hyperextension- flexion injury after a trauma such as a rear end impact car crash, contact sport injuries, blows to the head from a falling object or a punch and shaken baby syndrome and is mostly seen in adults . It is important as it may cause severe disability due to spinal cord injury, decrease work productivity and even retropharyngeal hematoma resulting airway obstruction and mortality due to bleeding amongst deep cervical fascias. We describe a case of retropharyngeal hematoma after whiplash injury in a childhood.

    Background Initial optimal management of acute type A aortic dissection (ATAAD) with intramural hematoma (ATAIMH) remains controversial, especially between centers in the Eastern vs. Western worlds. We examined the literature and our experience to report outcomes after repair of ATAIMH. Methods We reviewed the hospital, follow-up clinic records and online mortality databases for all patients who presented to our center for open repair of ATAAD between 1999 and 2014. Preoperative characteristics, early and long-term outcomes were compared between classic ATAAD vs. ATAIMH. Survival was analyzed using Kaplan-Meier and log-rank statistics. Results Of the 523 repaired ATAAD, 101 patients (19%) presented with IMH and 422 (81%) had classic dissection. ATAIMH were significantly older (64.8±12.9 vs. 56.8±14.6 years; P<0.001), more commonly females (39% vs. 26%; P=0.010), had poor baseline renal function (i.e., glomerular filtration rate) (P<0.017), more retrograde dissections (27% vs. 8.3%; P<0.001), and less distal malperfusion (5% vs. 15%; P<0.001). Age greater than 60 years, female sex, retrograde dissection, and Marfan syndrome were strongly correlated with ATAIMH. Time to repair for ATAIMH was longer (median, 55.3 vs. 9.8 hours; P<0.001) with one death in ATAIMH within three days of presentation (0.9% vs. 6%; P=0.040). In all, 30-day mortality in ATAIMH was not different from classic ATAAD (12% vs.16%; P=0.289). A significantly lower incidence of postoperative dialysis in ATAIMH was noted (10% vs. 19%; P=0.034). When adjusted for age and renal function, late survival was improved with IMH (P<0.039). Conclusions ATAIMH continues to be associated with significant morbidity and mortality, comparable to classic aortic dissection. A multidisciplinary management approach involving aggressive medical management and risk stratification for timely surgical intervention, along with genetic profiling, is recommended for optimal care. Long-term monitoring is mandatory to assess

    A Grazing Incidence Beam Expander (GIBE) telescope is being designed and fabricated to be used as an equivalent end mirror in a long laser resonator cavity. The design requirements for this GIBE flow down from a generic Free Electron Laser (FEL) resonator. The nature of the FEL gain volume (a thin, pencil-like, on-axis region) dictates that the output beam be very small. Such a thin beam with the high power levels characteristic of FELs would have to travel perhaps hundreds of meters or more before expanding enough to allow reflection from cooled mirrors. A GIBE, on the other hand, would allow placing these optics closer to the gain region and thus reduces the cavity lengths substantially. Results are presented relating to optical and mechanical design, alignment sensitivity analysis, radius of curvature analysis, laser cavity stability analysis of a linear stable concentric laser cavity with a GIBE. Fabrication details of the GIBE are also given.

    Conclusion: Our literature search did not reveal any evidence of SCS therapy among patients with chronic anticoagulation. This case illustrated a complicated clinical case scenario wherein a percutaneous SCS implantation would normally be contraindicated due to severe thoracic spinal stenosis and chronic anticoagulation which could lead to possible paralysis or even a lethal consequences associated with the possible formation of a thoracic epidural hematoma.

  18. Spontaneous sublingual and intramural small-bowel hematoma in a patient on oral anticoagulation

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

    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.

    Objective:To evaluate the influence of different hematoma clearance rates patients with hypertensive intracerebral hemorrhage.Methods: A total of 94 cases with hypertensive intracerebral hemorrhage treated with operation from June 2012 to June 2015 were selected. According to theirhematoma clearance rates, they were divided into groups A (50%-70%, 28 cases), B (70%-90%,48 cases) and C (90%, 18 cases). The recovery and perioperative levels of serum neuron-specific enolase (NSE) and soluble S-100 protein of the three groups were compared.Results: The perioperative mortality and the rates of postoperative rebleeding, intracranial infection and other complications of the three groups showed no statistical significant difference (P>0.05). With the increase of the hematoma clearance rate, the drainage tube removal time and hematoma complete absorption time reduced significantly (P<0.05). In the groups B and C, the grade levels of ADL in postoperative 3 months were significantly superior to those in the group A (P<0.05). The levels of serum NSE and S-100 in the three groups increased in the initial stage and then declined after surgery. In the group B and C, the serum levels of NSE and S-100 were significantly higher than those in the group A on the 7th day after surgery (P<0.05). With the increase of the hematoma clearance rate, the serum levels of NSE and S-100 were significantly reduced on the 14th day after surgery (P<0.05). Conclusions:High level of hematoma clearance rate can help to increase the operation efficacy and prognosis of patients with hypertensive intracerebral hemorrhage.

  12. The role of CT in pelvic fracture. CT finding of retro-peritoneal hematoma and indication of transcatheter arterial embolization

    Although retro-peritoneal hematoma accompanying a pelvic fracture has been treated by arterial ligation formerly, it is associated with a high mortality rate and a transcatheter arterial embolization has now become the first choice of treatment. Meanwhile, the usefulness of computed tomography (CT) in traumatized patient has been reported frequently. Our hospital also employs CT positively as an examination following plain radiography in the cases with pelvic fracture. However, while indication of angiography is seen in several reports, the amount of retro-peritoneal hematoma as an index has not been reported. In the present study, we examined 112 patients given CT at the time of examination at the emergency center of our hospital between April 1, 1988, and June 30, 1997, and classified the amount of retro-peritoneal hematoma on CT into 5 groups to discuss indication of angiography. In the cases with moderate or massive amount of retro-peritoneal hematomas, cases with shock state exceeded 60% and the amount of hematoma was considered to reflect the circulation profile to a certain extent. As the amount of retro-peritoneal hematoma increased, the number of cases given embolization also increased; embolization was performed in 29 cases (61.7%) among those which had moderate or massive amount of hematoma. From the above findings, it was predicted that the amount of retro-peritoneal hematoma could be one of the deciding factors for indication of angiography. However, as there are cases falling into a shock state due to gradual increase of hematoma or associated with injuries in other organs, careful observation is needed for the cases judged out of indication.

    Full Text Available The aim is to present a rare case of ligamentum flavum hematoma in the lumbar region, discuss its physiopathology and treatment and review the literature. A woman aged 68 presented with neurogenic claudication due to degenerative lumbar spondylolisthesis that evolved into a sudden worsening with cauda equina syndrome. The magnetic resonance imagining (MRI showed signs of degeneration of the lumbar spine, with a narrow spinal canal from L2 to S1, anterolisthesis L4 L5 and an expansive lesion hyperintense on T1-weighted and hypointense on T2-weighted images considered compatible with hematoma in the topography of the yellow ligament in L1-L2. The patient underwent laminectomy and lumbar fixation. Her evolution was good in the postoperative period and at 18 months of follow-up hse walked alone, despite the pain that is controlled with simple medications. Even though rare, it seems that ligamentum flavum hematoma has a relationship with the degeneration and rupture of small vessels associated with micro trauma to the spine. Its physiopathology is not well defined and treatment is similar to other spine compression processes.El objetivo es presentar un caso raro de un hematoma ligamento flavum en la región lumbar, discutir su fisiopatología y el tratamiento y revisión de la literatura.

    A basic understanding of the magnetic properties of Hb degradation products explains the mechanisms and production of the signals occurring at the different stages of the formation and degradation of intracranial hematoma and SAH. Despite the interaction among complex phenomena and the fact that their explanations are not univocal, since many phenomena remain to be understood even in the light of those theories that, at present, most closely agree, the proposed models permit the comprehension and diagnosis of a pathology which, in addition to being common, is diagnostically relevant and serves as paradigm in Radiological research.

    2005-07-29

    The cosmos is an awfully big place and there is no better guide to its vast expanse and fascinating nooks and crannies than John Barrow. A professor of mathematical sciences at Cambridge University, Barrow embodies that rare combination of highly polished writer and expert scientist. His deft touch brings together the disparate threads of human knowledge and weaves them into a tapestry as rich and interesting for the expert as it is for the layperson. The Artful Universe Expanded is an updated edition of this popular book first published in 1995. It explores the deeply profound manner in which natural law and the nature of the cosmos have moulded and shaped us, our cultures and the very form of our arts and music-a new type of 'cosmic' anthropology. The main themes Barrow chooses for revealing this new anthropology are the subjects of evolution, the size of things, the heavens and the nature of music. The book is a large, eclectic repository of knowledge often unavailable to the layperson, hidden in esoteric libraries around the world. It rivals The Da Vinci Code for entertainment value and insights, but this time it is Nature's code that is revealed. It is rare indeed to find common threads drawn through topics as diverse as The Beetles, Bach and Beethoven or between Jackson Pollock, the Aztecs, Kant, Picasso, Byzantine mosaics, uranium-235 and the helix nebula. Barrow unerringly binds them together, presenting them in a stimulating, conversational style that belies the amount of time that must have gone into researching this book. Dip into it at random, or read it from cover to cover, but do read it. The Artful Universe Expanded is an entertaining antidote to the oft-lamented pressures to know more and more about less and less and the apparently inexorable march of specialization. On reading this book one can, for a short time at least, hold in one's mind a vision that unifies science, art and culture and glimpse a universal tapestry of great

    Sublingual hematoma secondary to excessive anticoagulation is a rare, life-threatening condition. Reports in the literature have emphasized the importance of a prompt reversal of the causative coagulopathy by intravenous administration of vitamin K and fresh frozen plasma. In the event of an unstable airway, surgical intervention via tracheostomy or cricothyroidectomy is advocated. We report a case of sublingual hematoma that was treated conservatively, and we discuss the presentation and management of this entity.

    Hutchinson-Gilford progeria syndrome (HGPS) is a very rare genetic disorder characterized by premature ageing, severe growth failure, and very early onset atherosclerosis. Psychologically and emotionally child-like, these patients suffer from physiological changes of old age. Early and progressive atherosclerosis of intra-cranial vessels in HGPS patients, along with a thin skin and fragile vessels, make these patients susceptible to intra-cranial hematomas following relatively trivial injuries and to severe intra-cranial disease. Anesthetizing HGPS patients for surgery can be challenging due to the presence of a possible difficult airway, multi-system derangements, and associated skin, bone and joint disease. We report here one such child with HGPS who underwent craniotomy and evacuation of an extradural hematoma that developed after minor head trauma. Securing his airway during surgery was difficult.

    A 74-year-old man was hospitalized due to hematemesis. Upper gastrointestinal endoscopy revealed a very large and dark red mass in the cardiac region of the stomach that extended from the upper esophagus. A biopsy specimen showed hemorrhagic tissue and no malignant cells. The tumor-like region ulcerated at 5 days after the administration of intravenous lansoprazole at a dose of 30 mg twice a day and resolved with scar formation at 2 months after a change to oral rabeprazole at a dose of 10 mg/day.We diagnosed the patient with gastroesophageal submucosal hematoma. Gastroesophageal submucosal hematoma is a rare complication. In this case, we could follow the process of its disappearance by endoscopy.

    Full Text Available A 2½-year-old male child with a prior history of a left anatomic hemispherectomy to treat refractory epilepsy fell down two steps, striking his head on the ipsilateral side of the hemispherectomy. He presented with non-consolable crying and emesis. CT scan of the head demonstrated a left frontal epidural hematoma beneath the site of his prior craniectomy. The patient was initially treated by close observation. However, due to an increase in the hematoma from 29.5 to 49.3 ml over a 12-hour period along with the patient′s lack of clinical improvement, surgical evacuation was performed. Intraoperatively, the source of the hemorrhage was found to be the skull fracture. Postoperatively, he returned to his neurologic baseline and was discharged home on postoperative day 3.

    Hemobilia is a rare biliary complication of liver transplantation.The predominant cause of hemobilia is iatrogenic,and it is often associated with traumatic operations,such as percutaneous liver intervention,endoscopic retrograde cholangiopancreatography,cholecystectomy,biliary tract surgery,and liver transplantation.Percutaneous transhepatic cholangiography and liver biopsy are two major causes of hemobilia in liver transplant recipients.Hemobilia may also be caused by coagulation defects.It can form intracholedochal hematomas,causing obstructive jaundice.Herein we describe a patient with an intracholedochal hematoma resulting in significant obstructive jaundice after liver transplantation for fulminant hepatic failure.Previous studies have shown that percutaneous transhepatic manipulation is a major cause of hemobilia after liver transplantation,but in our case,percutaneous transhepatic intervention was used to relieve the biliary obstruction and dissolve the biliary clot,with a good outcome.

    Background and Objective Brain edema is one of the most important clinical process in many diseases. Tissue impedance monitoring offers a non-invasive, bedside, rapid, and reliable technique for the monitoring of the brain edema. Methods We use a bioelectrical impedance(BEI) monitoring unit to record the brain impedance in the healthy volunteer and the patients with intracerebral hemorrhage. Percent of BEI variations were calculation. Results and Conclusions Brain BEI haven f any difference between both hemispheres in normal ones. In 48hrs, BEI value at hematoma-side was obviously decreased; after 48hrs, BEI value was obviously increased and continue to tenth day. Brain bioelectrical impedance monitoring, particularly noninvasively, is a first time in this field. The primary results show brain BEI could reflect the evolution of cerebral hematoma and edema.

    Intraventricular hemorrhage (IVH) is a neurological urgency with a high mortality and unfavorable prognosis.Fast removal of intraventricular blood should be considered as a priority.The current treatments of IVH mainly focus on external ventricular drain and endoscopic aspiration,but neither way can remove the blood in the fourth ventricle easily and relieve the compression of brainstem.Here we report a unique procedure to solve this problem.A 41-year-old male patient who had suffered sudden attack of headache and disturbance of consciousness for 2 h was diagnosed as having high density lesion in thewhole ventricular system by computed tomographic (CT) imaging.An emergent bilateral ventriculopuncture and intraventricular hematoma removal under non-line-of-sight was performed immediately;the catheter was extended to the fourth ventricle to maximally remove the hematoma.Postoperative CT scan demonstrated total removal of IVH and no sign of extra brain damage.

    Full Text Available Hutchinson-Gilford progeria syndrome (HGPS is a very rare genetic disorder characterized by premature ageing, severe growth failure, and very early onset atherosclerosis. Psychologically and emotionally child-like, these patients suffer from physiological changes of old age. Early and progressive atherosclerosis of intra-cranial vessels in HGPS patients, along with a thin skin and fragile vessels, make these patients susceptible to intra-cranial hematomas following relatively trivial injuries and to severe intra-cranial disease. Anesthetizing HGPS patients for surgery can be challenging due to the presence of a possible difficult airway, multi-system derangements, and associated skin, bone and joint disease. We report here one such child with HGPS who underwent craniotomy and evacuation of an extradural hematoma that developed after minor head trauma. Securing his airway during surgery was difficult.

    2014-01-01

    The authors report five cases of pelvic hematoma without associated pelvic fracture after military static-line parachute operations, a significantly underreported injury. The case reports and discussion include initial emergency department presentation, stabilization requirements, and imaging, disposition, and management recommendations. Data were collected retrospectively through review of medical records from a single institution over the course of a single calendar year, 2012-2013. Pelvic hematoma should be strongly considered in the patient with lower abdominal, hip, or pelvic pain after blunt injury from parachute landing fall even in the absence of associated fracture. The cases discussed display this underreported injury and highlight the frequent necessity for admission to a high-acuity care center for close monitoring.

    Spontaneous or traumatic intramural bleeding of the esophagus, which is often associated with overlying mucosal dissection, constitutes a rare spectrum of esophageal injury called dissecting intramural hematoma of the esophagus (DIHE). Chest pain, swallowing difficulty, and minor hematemesis are common, which resolve spontaneously in most cases. This case report describes a patient with spontaneous DIHE with recurrent massive bleeding which required critical management and highlights a potential role for therapeutic angiography as an alternative to surgery.

    Ultrasound-guided regional anesthetic techniques have shown some advantages over conventional paresthesia and neurostimulation techniques. We report the case of a neurostimulation-guided continuous interscalene block that would have ended in complication were it not for experience with ultrasound-guided regional anesthesia. Familiarity with ultrasound-guided block techniques permitted assessment of a neck hematoma during interscalene block and ultimately allowed successful peripheral nerve block.

    Full Text Available Abstract Introduction Subarachnoid hemorrhages of spinal origin are extremely rare during pregnancy. We present the case of a patient with hemolytic anemia, elevated liver enzymes and low platelet count (the so-called HELLP syndrome, a potentially life-threatening complication associated with pre-eclampsia, who presented with an idiopathic spinal subarachnoid hematoma. Case presentation At 29 gestational weeks, a 35-year-old Japanese woman was diagnosed with HELLP syndrome based on bilateral leg paralysis, diminished sensation and reflexes, and laboratory findings. The pregnancy was immediately brought to an end by Cesarean delivery. Post-operatively, an MRI scan revealed a space-occupying lesion in her thoracic spinal canal. Emergency decompression was followed by total laminectomy. A subarachnoid hematoma, partially extending as far as the ventral side, was removed. After thorough washing and drain placement, the operation was completed with the suturing of artificial dura mater. Eight months post-operatively, her lower extremity sensation had improved to a score of 8 out of 10, but improvements in her muscular strength were limited to slight gains in her toes. MRI scans taken two months post-operatively revealed edematous spinal cord changes within her medulla. Conclusions A subarachnoid hematoma during pregnancy is extremely rare, possibly due to increased coagulability during pregnancy. However, this complication is potentially devastating should a clot compress the spinal cord or cauda equina. While several causes of hematoma have been proposed, we speculate that the factors underlying hemorrhagic diathesis in our case were the decreased platelet count characteristic of HELLP syndrome and vascular fragility due to elevated estrogen levels, in addition to increased abdominal pressure during pregnancy and pressure from the gravid uterus resulting in ruptured vessels around the spinal cord. In cases displaying a progressive lesion and severe

    2016-01-01

    Full Text Available Background: Malignant peripheral nerve sheath tumors (MPNSTs of the brachial plexus have unique radiographic and clinical findings. Patients often present with progressive upper extremity paresthesias, weakness, and pain. On magnetic resonance (MR imaging, lesions are isointense on T1-weighted and hyperintense on T2-weighted sequences, while also demonstrating marked enhancement on MR studies with gadolinium diethylenetriamine pentaacetic acid. On the basis of their characteristic MR imaging features and rapid clinical progression, two brachial plexus lesions proved to be organizing hematomas rather than MPNST. Methods: A 51-year-old male and a 31-year-old female were both assessed for persistent and worsened left-sided upper extremity pain, paresthesias, and weakness. In both cases, the MR imaging of the brachial plexus demonstrated an extraspinal enhancing lesion located within the left C7-T1 neuroforamina. Results: Although the clinical and radiographic MR features for these 2 patients were consistent with MPNSTs, both lesions proved to be benign organizing hematomas. Conclusions: These two case studies emphasize that brachial plexus hematomas may mimic MPNSTs on MR studies. Accurate diagnosis of these lesions is critical for determining the appropriate management options and treatment plans. Delaying the treatment of a highly aggressive nerve sheath tumor can have devastating consequences, whereas many hematomas resolve without surgery. Therefore, if the patient has stable findings on neurological examination and a history of trauma, surgical intervention may be delayed in favor of repeat MR imaging in 2-3 months to re-evaluate the size of the mass.

    Barrow, John D.

    2005-07-01

    Our love of art, writes John Barrow, is the end product of millions of years of evolution. How we react to a beautiful painting or symphony draws upon instincts laid down long before humans existed. Now, in this enhanced edition of the highly popular The Artful Universe , Barrow further explores the close ties between our aesthetic appreciation and the basic nature of the Universe. Barrow argues that the laws of the Universe have imprinted themselves upon our thoughts and actions in subtle and unexpected ways. Why do we like certain types of art or music? What games and puzzles do we find challenging? Why do so many myths and legends have common elements? In this eclectic and entertaining survey, Barrow answers these questions and more as he explains how the landscape of the Universe has influenced the development of philosophy and mythology, and how millions of years of evolutionary history have fashioned our attraction to certain patterns of sound and color. Barrow casts the story of human creativity and thought in a fascinating light, considering such diverse topics as our instinct for language, the origins and uses of color in nature, why we divide time into intervals as we do, the sources of our appreciation of landscape painting, and whether computer-generated fractal art is really art. Drawing on a wide variety of examples, from the theological questions raised by St. Augustine and C.S. Lewis to the relationship between the pure math of Pythagoras and the music of the Beatles, The Artful Universe Expanded covers new ground and enters a wide-ranging debate about the meaning and significance of the links between art and science.

    Common complications related to transrectal ultrasound (TRUS) guided prostatic needle biopsy are hematuria, hematospermia, and hematochezia. To the best of our knowledge, we report the second case of a very large hematoma extending from the pelvis into the retroperitoneal space in literature.A 66-year-old man with a serum prostate-specific antigen (PSA) of 5.4 ng/ml was admitted to our department for a TRUS-guided prostatic needle biopsy. Laboratory values on the day before biopsy, including coagulation studies, were all normal. The patients did not take any anticoagulant drugs. No immediate complications were encountered. Nevertheless, 7 hours after the biopsy, the patient reached our emergency department with severe diffuse abdominal pain, hypotension, tachycardia, and confusional state. He underwent an ultrasonography and then a computed tomography (CT) scan that showed "a blood collection in the pelvis that extending to the lower pole of left kidney associated with a focus of active contrast extravasation, indicating active ongoing prostate bleeding." Consequently, he underwent a diagnostic angiography that showed no more contrast extravasation, without the need of embolization. Management of hematoma has been conservative and hematoma was completely reabsorbed 4 months later.

    Gastric intramural hematoma is a rare injury of the stomach,and is most often seen in patients with underlying disease.Such injury following endoscopic therapy is even rarer,and there are no universally accepted guidelines for its treatment.In this case report,we describe a gastric intramural hematoma which occurred within 6 h of endoscopic mucosal resection (EMR).Past medical history of this patient was negative,and laboratory examinations revealed normal coagulation profiles and platelet count.Following EMR,the patient experienced severe epigastric pain and vomited 150 mLof gastric contents which were bright red in color.Subsequent emergency endoscopy showed a 4 cm × 5 cm diverticulum-like defect in the anterior gastric antrum wall and a 4 cm × 8 cm intramural hematoma adjacent to the endoscopic submucosal dissection lesion.Following unsatisfactory temporary conservative management,the patient was treated surgically and made a complete recovery.Retrospectively,one possible reason for the patient's condition is that the arterioles in the submucosa or muscularis may have been damaged during deep and massive submucosal injection.Thus,endoscopists should be aware of this potential complication and improve the level of surgery,especially the skills required for submucosal injection.

  2. Drug interaction as cause of spontaneously resolving epidural spinal hematoma on warfarin therapy

    Full Text Available We present a case of a 42-year-old male, an old case of deep vein thrombosis on warfarin and other drugs like quetiapine, aspirin, diclofenac sodium, fenofibrate, atorvastatin, propanolol and citalopram for concurrent illnesses, who presented with widespread mucocutaneous bleeding and epidural spinal hematoma. The epidural bleed presented clinically as a nontraumatic, rapidly improving myeloradiculopathy. Magnetic resonance imaging (MRI of the spine revealed an epidural hematoma at D12-L1 level. The case was managed conservatively due lack of neurosurgical facilities. The patient gained full neurological recovery on conservative management alone. This case highlights the problem of drug interaction on warfarin therapy and also an unusual spontaneous recovery of spinal hematoma. Our case was anticoagulated in the recommended therapeutic INR range of 2.2 to 2.4. Most of the similar cases reported in literature were also anticoagulated in the therapeutic range. Thus intraspinal hemorrhage is a rare but dangerous complication of anticoagulant therapy. It must be suspected in any patient on anticoagulant agents who complains of local or referred spinal pain associated with neurological deficits. Drug interactions with warfarin are common. High suspicion and immediate intervention are essential to prevent complications from intraspinal hemorrhage.

    We reported a case of an abdominal wall hematoma which caused by Seldinger method via the femoral artery. A 48-year-old female, suffered from direct carotid cavernous fistula, was treated by transfemoral transvenous embolization (TVE). The whole procedure was completed without difficulty except minor resistance of guide wire manipulation during left femoral artery catheterization. Four hours later, the patient became hypotensive and showed the sign of impending shock without definitive causes. Nine hours after the embolization a huge hematoma of the abdominal wall was found. It required the total 1200 m/ of blood transfusion before her blood pressure returned to normal. She recovered fully from this event and discharged uneventfully. There is a speculation that a deep circumflex iliac artery (DCIA) was injured with an angle-shaped guide wire and bled into the abdominal wall. And subsequent systemic heparinization prevented the coagulation process, resulting a large hematoma. Anatomically, an angle-shaped guide wire is easily able to migrate into DCIA. To prevent a vascular injury, it is very important to manipulate a guide wire under fluoroscopic control and to select a J-shaped guide wire instead of an angle-shaped one.

    Intracerebral hemorrhage (ICH) is associated with high mortality and disability, and there is no widely approved clinical therapy. Poor outcome after ICH results mostly from a mass effect owing to enlargement of the hematoma and brain swelling, leading to displacement and disruption of brain structures. Cerebral mast cells (MC) are resident inflammatory cells that are located perivascularly and contain potent vasoactive, proteolytic, and fibrinolytic substances. We previously found pharmacological MC stabilization and genetic MC deficiency to be associated with up to 50% reduction of postischemic brain swelling in rats. Here, we studied the role of MC and MC stabilization in ICH using in vivo magnetic resonance imaging and ex vivo digital imaging for calculating brain edema and hematoma volume. In a rat ICH model of autologous blood injection into the basal ganglia, four groups of Wistar rats received either saline or sodium cromoglycate (MC stabilizer, two groups) or compound 48/80 (MC degranulator). Evaluated 24 h later, MC stabilization had resulted in highly significantly better neurologic scores (Pbrain swelling (Pbrain swelling (P<0.05), and smaller hematoma growth (P<0.05) than WT. The role of MC deserves a close evaluation as a potential target in the development of novel forms of ICH therapy.

    2014-01-01

    Full Text Available Spontaneous rectus sheath hematoma (SRSH is an uncommon medical emergency in the elderly. We present a case of SRSH with an atypical clinical presentation and discuss literature regarding diagnosis and proper management. A 75-year-old female patient was transferred to the emergency department due to acute dyspnoea and confusion. Her medical history revealed a viral infection of the upper respiratory tract, and no coughing or use of anticoagulants. The clinical examination showed tenderness of the left lower abdomen, although palpation was misleading due to patient’s obesity. Laboratory investigations showed light anaemia. Ultrasonography and computed tomography revealed a large rectus sheath hematoma of the left abdominal wall. Despite further deterioration of the patient, conservative management including bed rest, fluid replacement, blood products transfusion, and proper analgesia was successful. No surgical intervention was needed. Prompt diagnosis and management of SRSH plays significant role in the prognosis, especially in elder patients. Independently of size and severity, conservative management remains the first therapeutic choice. Only by failure of supportive management, progressive and large hematoma or uncontrollable hemodynamic patients, interventional management including surgery or less invasive newer techniques is indicated.

    The U.S. military has been conducting static-line parachute jumps for nearly a century. Beginning with World War II, military forces have also employed full-scale airborne operations as a method for insertion into combat. Through the years, injuries from blunt trauma as a result of static-line parachute jumps have evolved little with the refinement of equipment, training, and tactics. Parachute jumps continue to invoke primarily musculoskeletal injuries, especially to the lower extremities, back, neck, and head. These injuries are usually straightforward in their presentation and diagnosis. We describe the delayed diagnosis of a pelvic hematoma due to an uncommon blunt trauma jump injury. The purpose of this case report is to increase awareness of injury patterns during paratrooper operations, as well as to review the diagnosis and management of occult hemorrhage. Specific objectives for the readers are to (1) know the common injury types and patterns for airborne operations, (2) know the descent rate of T-10C/D parachutes and factors influencing the rate, (3) recognize signs and symptoms associated with a pelvic hematoma, and (4) recognize common complications resulting from a pelvic hematoma.

    Full Text Available Abstract Introduction Vascular complications related to cup-fixating screws penetrating the medial acetabular wall during total hip arthroplasty are not uncommon but rarely are associated with serious adverse events in the late post-operative period. Case presentation We present the case of a 77-year-old Japanese woman who developed progressive extensive bone resorption and large hematoma in the acetabulum 13 years after total hip arthroplasty. On admission to our hospital, she was on oral warfarin (1.5mg/day for atrial fibrillation. About 5 months after the initiation of anticoagulant therapy, she suffered a major fall followed by massive subcutaneous and pelvic girdle bleeding, predominantly on the medial side of the right thigh, but a fracture or damage of total hip arthroplasty was not evident on an emergency orthopedic evaluation. One year after the accident, a routine follow-up examination showed an asymptomatic osteolytic lesion in the acetabulum on the right pelvis, and 2 years later our patient noticed progressive pain in her right hip during walking. A large osteolytic lesion was noted in the right acetabulum on a plain radiograph. On high-resolution computed tomography and magnetic resonance imaging, a huge granulomatous lesion in the acetabulum was suggestive of chronic hematoma in intrapelvic and extrapelvic gluteal regions. A closer computed tomography examination showed that one of the screws used for fixation of the acetabular component in the total hip arthroplasty had penetrated the acetabular bone and had reached the pelvic cavity. Surgery was performed in a single session by means of two approaches: anterior midline transperitoneal address to resect the low-density mass lesion followed by posterolateral acetabular implant re-settlement. Conclusions Though rare, total hip arthroplasty-related late vascular complications could be serious and potentially affect the limb and quality of life.

    Background Despite low morbidity, acute or subacute spinal epidural hematoma may develop quickly with a high tendency to paralysis. The delay of diagnosis and therapy often leads to serious consequences. In this study we evaluated the effects of a series of methods for the diagnosis and treatment of the hematoma in 11 patients seen in our hospital.Methods Of the 11 patients (8 males and 3 females), 2 had the hematoma involving cervical segments, 2 cervico-thoracic, 4 thoracic, 1 thoraco-lumbar, and 2 lumbar. Three patients had quadriplegia, including one with central cord syndrome; another had Brown-Sequard's syndrome; and the other seven had paraplegia. Five patients were diagnosed at our hospitals within 3-48 hours afterappearance of symptoms, and 6 patients were transferred from community hospitals within 21-106 hours after development of symptoms. Key dermal points, key muscles and the rectal sphincter were determined according to the American Spinal Injury Society Impairment Scales as scale A in two patients,B in 5 and C in 4. Emergency MRI in each patient confirmed that the dura mater was compressed in the spinal canal, with equal intensity or hyperintensity on T1 weighted image and mixed hyperintensity on T2 weighted image. Preventive and curative measures were taken preoperatively and emergency operation was performed in all patients. Open laminoplasty was done at the cervical and cervico-thoracic segments, laminectomy at the thoracic segments, laminectomy with pedicle screw fixation at the thoraco-lumbar and lumbar segments involving multiple levels, and double-sided laminectomy with the integrity of articular processes at the lumbar segments involving only a single level. During the operation, special attention was given to hematoma evacuation, hemostasis and drainage tube placement.Results Neither uncontrollable hemorrhage nor postoperative complications occurred. All patients were followed up for 1-6 years. A marked difference was noted between

    Near-Infrared Spectroscopy (NIRS) is an emerging medical countermeasure for rapid, field detection of hematomas caused by traumatic brain injury (TBI). Bench and animal tests to determine NIRS sensitivity and specificity are needed. However, current animal models involving non-invasively induced, localized neural damage are limited. We investigated an in vivo murine hematoma model in which cerebral hemorrhage was induced noninvasively by high-intensity focused ultrasound (HIFU) with calibrated positioning and parameters. To characterize the morphology of induced hematomas, we used skull-intact histological evaluation. A multi-wavelength fiber-optic NIRS system with three source-detector separation distances was used to detect hematoma A 1.1 MHz transducer produced consistent small-to-medium hematoma localized to a single hemisphere, along with bruising of the scalp, with a low mortality rate. A 220 kHz transducer produced larger, more diffuse hematomas, with higher variability in size and a correspondingly higher mortality rate. No skin bruising or blood accumulation between the skin and skull was observed following injury application with the 220 kHz transducer. Histological analysis showed higher sensitivity for larger hematomas (>4x4 mm2). NIRS optical density change after HIFU was able to detect all hematomas, with sensitivity dependent on wavelength and separation distance. While improvements in methods for validating cerebral blood distribution are needed, the HIFU hematoma model provided useful insights that will inform development of biologically relevant, performance test methods for cerebral NIRS systems.

    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.

    Background Given the increasing number of patients who require dual antiplatelet (DAP) therapy and electrophysiological device (EPD) placement, perioperative antiplatelet management is a current challenge. In this study, we investigated the incidence of pocket hema-toma formation after EPD placement in patients undergoing DAP therapy or an alternative low-molecular-weight heparin (LMWH) regimen. Methods This clinical observational study was performed from July 2010 to July 2012. In total, 171 patients were enrolled in the analysis after meeting the inclusion criteria. These patients were divided into two groups: 86 patients were treated with DAP therapy at the time of device implantation, and the DAP therapy was discontinued for 5 to 7 days and replaced with enoxaparin before device implantation in the other 85 patients. Adenosine phosphate (ADP)-mediated platelet aggregation and arachidonic acid-induced platelet aggregation were tested preoperatively. We compared the incidence of pocket hematoma between the two groups and the association of pocket hematoma develop-ment with ADP-mediated platelet aggregation and arachidonic acid-induced platelet aggregation.Results The incidence of pocket hema-toma in the patients who continued DAP was lower than that in the patients who replaced the dual antiplatelet regimen with LMWH (3.49%vs. 16.47%, respectively;X2 = 6.66,P < 0.01). Among the patients who continued DAP therapies, the rate of ADP-mediated platelet aggre-gation inhibition in patients with pocket hematomas was higher than that in patients without pocket hematomas. None of the patients under-going DAP or enoxaparin therapy developed pocket infection, thromboembolic events, or other serious complications. Multiple logistic re-gression analysis revealed that LMWH therapy was an independent risk factor for the development of pocket hematoma (RR = 0.054, 95%CI = 0.012-0.251). Furthermore, patients undergoing LMWH therapy were 5.1-fold more likely to develop pocket

    Patients with traumatic hematomas or those with indwelling catheters who subsequently develop fever and sepsis without clinical localizing signs to indicate an inflammatory focus can present a diagnostic dilemma. Early diagnosis of an infected hematoma or thrombus is important to optimal management. CT can provide, exquisite delineation of anatomy identifying and localizing a post-traumatic fluid collection but cannot reliably distinguish hematoma from abscess in all cases. A thrombus at a catheter tip may be too small to be resolved; when identified, the question of infection again remains. In-111 leukocyte scanning provides a method for identifying or ruling out infection in these situations. The authors performed In-111 leukocyte scans on 15 patients with indwelling catheters. Five of these patients were febrile with positive blood cultures. In-111 leukocyte scans showed positive findings in 8 patients: 5 showed surgically confirmed infected hematomas in the abdomen (3 in the pelvis, 1 in a kidney, 1 in the splenic bed), and 3 showed infected thrombosis in catheter tips. The authors conclude that CT scanning and In-111 leukocyte scanning play complementary roles in the evaluation of traumatic hematomas and thrombosis, the former providing precise anatomic delineation and the latter providing evidence of inflammation.

    Full Text Available Background. Fibromuscular dysplasia (FMD is a vascular disease that may present as aneurysms in the cervical arteries. Spontaneous neck hematoma is a rare life threatening medical condition. This is the first report of neck hematoma in a patient with FMD. Methods and Results. We present a case of a 69-year-old woman, with diagnosed cervical FMD and a 3-day history of sore throat and neck pain, who presented with enlarging neck hematoma. No active bleeding was noticed on CT angiography, airway was not compromised, and patient was managed conservatively. Next day, invasive angiography was performed, and no bleeding vessel was demonstrated. Patient has improved and was discharged after 5 days of hospitalization. We have discussed the different etiology of this condition, focusing on systemic vascular diseases. Conclusion. Complaint of neck pain in a patient with a FMD should raise suspicion for possible neck hematoma. Conversely, spontaneous neck hematoma without clear etiology should raise suspicion for a systemic vascular disease.

    Rapid, on-the-spot diagnostic and monitoring systems are vital for the survival of patients with intracranial hematoma, as their conditions drastically deteriorate with time. To address the limited accessibility, high costs and static structure of currently used MRI and CT scanners, a portable non-invasive multi-slice microwave imaging system is presented for accurate 3D localization of hematoma inside human head. This diagnostic system provides fast data acquisition and imaging compared to the existing systems by means of a compact array of low-profile, unidirectional antennas with wideband operation. The 3D printed low-cost and portable system can be installed in an ambulance for rapid on-site diagnosis by paramedics. In this paper, the multi-slice head imaging system’s operating principle is numerically analysed and experimentally validated on realistic head phantoms. Quantitative analyses demonstrate that the multi-slice head imaging system is able to generate better quality reconstructed images providing 70% higher average signal to clutter ratio, 25% enhanced maximum signal to clutter ratio and with around 60% hematoma target localization compared to the previous head imaging systems. Nevertheless, numerical and experimental results demonstrate that previous reported 2D imaging systems are vulnerable to localization error, which is overcome in the presented multi-slice 3D imaging system. The non-ionizing system, which uses safe levels of very low microwave power, is also tested on human subjects. Results of realistic phantom and subjects demonstrate the feasibility of the system in future preclinical trials.

    Full Text Available Spontaneous spinal epidural hematoma (SSEH is a rare entity.SSEH is an accumulation of blood in the vertebral epidural space in the absence of trauma or iatrogenic procedure like lumbar puncture.The incidence of SSEH has been estimated at 0.1 patients per 100,000 individuals and represents less than 1% of spinal space-occupying lesions .Here we are presenting case of a 65year old female hypertensive on treatment with controlled blood pressure, who presented with sudden onset paraplegia and weakness of muscles of hand, associated with urinary and bowel incontinence that started 6 hours before presenting to Emergency Room .Patient was subjected to MRI spine that revealed a collection in spinal epidural space ,hypointense in T1W images and hyperintense in T2W images, extending from C6-C7 to T1-T2 suggestive of acute / subacute epidural hematoma (fig 1.In our case all possible causes of an epidural haematoma were ruled out by relevant investigations.Patient was subjected to surgical evacuation of hematoma after 48 hours of presentation.Perioperative and Postoperative period was uneventfull . Sensations over involved areas improved. Motor weakness also improved from Grade III to Grade IV+ in bilateral lower limbs and from Grade II to Grade IV in small muscles of hand and triceps, however Patient persisited with urinary incontinence.CONCLUSION: When a patient receiving anticoagulant therapy complains of sudden and unexplained neck or back pain, we should suspect the possibility of SSEH. For early diagnosis, immediate MRI is essential .In addition, we should consider SSEH as one of the important differential diagnoses in elderly patients who have developed acute myelopathy.

    Full Text Available Cranial fixation with pins is a routine adjunct in neurosurgery and is usually considered safe. A rarely reported complication is skull fracture at the pin site and consequent epidural hematoma. Usually, these are picked up only postoperatively and rarely, intraoperatively if there is unexplained “brain bulge” in which case the operation should be terminated and urgent imaging has to be done. We describe such a complication that occurred while operating on a 12-year-old child with a posterior fossa tumor and review the available literature dealing with such events.

Comparison of density values and repeated examination were useful to assert diagnosis and to appreciate the course of the illness. Only C.T. Scanner was able to show which portion of the muscle was concerned. Authors correlated the C.T. Scanner results to the nature of the entrapment neuropathy clinically found: an isolated femoral nerve palsy or association with an obturator nerve dysfunction.

    Full Text Available Subdural hematoma (SDH is a rare but serious complication of spinal anesthesia. We report a case of intracranial SDH in a patient developing 11 days after spinal anesthesia for cesarean section. The patient complained of headache on the 2nd post-operative day that was relieved by analgesics, bed rest and hydration. Later she presented with severe headache, vomiting, dizziness, dysarthria, irritability and somnolence. Diagnosis of the left sided SDH was confirmed radiologically and treated surgically. The patient recovered completely. The report highlights the need of considering the possibility of SDH in patients when postdural puncture headache is prolonged or recurs after a headache free period with neurological symptoms.

    Full Text Available Rectus Sheath Hematoma (RSH represents an unusual entity which is characterized by acute abdominal pain and tender palpable abdominal mass usually, among elderly patients receiving anticoagulant therapy. We report the case of an 81-year-old woman admitted to our department due to acute abdominal pain and oligoanuria. The patient had recently been hospitalized due to acute myocardial infarction (AMI and atrial fibrillation (AF and received both anticoagulant and antiplatelet therapies. The radiological assessments revealed an extended Rectus Sheath Hematoma and bilateral hydronephrosis. Treatment of the hematoma required cessation of anticoagulants and antiplatelet agents, immobilization, blood and fresh frozen plasma transfusion, and administration of vasopressors. The patient recovered gradually and was discharged home fifteen (15 days later.

    2010-05-01

    Full Text Available Abstract We described a 6 years follow-up of a spontaneous aortic intramural hematoma (IMH with cardiovascular magnetic resonance (CMR examination. Since multiple factors may play roles in the natural history of IMH, the patient experienced the course of progression, which included hematoma absorption, ulcer-like lesion, aneurysm and limited dissection. The initial and follow-up CMR examination included 3D CE MRA and non-enhanced "bright blood" pulse sequence. The inherent advantage of outstanding contrast with plain scan, which shorten the scan time and avoid potential risk of contrast agent, might make the fast gradient echo sequence as an alternative method when following stable IMH.

    The presence of a pelvic mass in a patient with an elevated serum CA-125 suggests the possibility of a gynecologic malignancy. However, an increasing number of nonneoplastic causes of elevated serum CA-125 have been reported. This is the first report of a pelvic hematoma associated with elevated serum CA-125. Two weeks following cardiac catheterization at time of myocardial infarction a patient was noted to have a complex pelvic mass on ultrasound and serum CA-125 of 53 units per milliliter. Abdominal-pelvic CT-scan showed a small left pleural effusion, minimal ascites, left lower quadrant abdominal wall masses consistent with omental metastases, and a 9.4 x 10.3 x 9.0-cm complex left adnexal mass. At exploratory laparotomy a large organized hematoma in the left paravesical space was adherent to both the left external iliac artery and the left bladder wall. This mass could have been managed expectantly with percutaneous aspiration if a nonmalignant diagnosis had been more strongly considered.

    We present a rare case of spinal epidural hematoma (SEH) after thoracolumbar posterior fusion without decompression surgery for a thoracic vertebral fracture. A 42-year-old man was hospitalized for a thoracic vertebral fracture caused by being sandwiched against his back on broken concrete block. Computed tomography revealed a T12 dislocation fracture of AO type B2, multiple bilateral rib fractures, and a right hemopneumothorax. Four days after the injury, in order to promote early orthostasis and to improve respiratory status, we performed thoracolumbar posterior fusion surgery without decompression; the patient had back pain but no neurological deficits. Three hours after surgery, he complained of acute pain and severe weakness of his bilateral lower extremities; with allodynia below the level of his umbilicus, postoperative SEH was diagnosed. We performed immediate revision surgery. After removal of the hematoma, his symptoms improved gradually, and he was discharged ambulatory one month after revision surgery. Through experience of this case, we should strongly consider the possibility of preexisting SEH before surgery, even in patients with no neurological deficits. We should also consider perioperative coagulopathy in patients with multiple trauma, as in this case. PMID:26989542

    Epidural hematoma (EDH) in newborn infants is rare compared with other types of intracranial hemorrhages. Furthermore, posterior fossa EDH is extremely rare. We present a case of posterior fossa EDH in an infant with Menkes disease with accessory bones in the occiput. A male infant with a condition diagnosed with Menkes disease by prenatal testing was born at 39 weeks via vacuum extraction. The patient presented with a mild tremor at 2 days after delivery. A brain computed tomography (CT) scan showed an acute EDH in the posterior fossa, extending into the occipitoparietal area. Three-dimensional CT and bone window CT scan revealed several accessory bones, diastasis of 1 accessory suture, a communicated fracture, and a linear fracture in the occipital bone. Furthermore, a bone fragment from a communicated fracture displaced toward the inside. The patient was treated conservatively for EDH because of his good general condition. The hematoma gradually resolved, and his tremor did not recur. We suggest the following mechanism of posterior fossa EDH development in our patient: (1) external force was applied to the occiput inside the birth canal during delivery, resulting in diastasis; (2) a communicated fracture occurred, and a bone fragment displaced toward the inside (linear fracture was caused indirectly by the force); (3) a transverse sinus was injured by the fragment; and (4) EDH developed in both the posterior fossa and supratentorial region. Copper deficiency can also cause fragility of connective tissues, vessels, and bones.

    2012-01-01

    Full Text Available Progressive epidural hematoma (PEDH after head injury is often observed on serial computerized tomography (CT scans. Recent advances in imaging modalities and treatment might affect its incidence and outcome. In this study, PEDH was observed in 9.2% of 412 head trauma patients in whom two CT scans were obtained within 24 hours of injury, and in a majority of cases, it developed within 3 days after injury. In multivariate logistic regression, patient gender, age, Glasgow Coma Scale (GCS score at admission, and skull fracture were not associated with PEDH, whereas hypotension (odds ratio (OR 0.38, 95% confidence interval (CI 0.17–0.84, time interval of the first CT scanning (OR 0.42, 95% CI 0.19–0.83, coagulopathy (OR 0.36, 95% CI 0.15–0.85, or decompressive craniectomy (DC (OR 0.46, 95% CI 0.21–0.97 was independently associated with an increased risk of PEDH. The 3-month postinjury outcome was similar in patients with PEDH and patients without PEDH (χ2=0.07, P=0.86. In conclusion, epidural hematoma has a greater tendency to progress early after injury, often in dramatic and rapid fashion. Recognition of this important treatable cause of secondary brain injury and the associated risk factors may help identify the group at risk and tailor management of patients with TBI.

    Full Text Available Background. Previous studies showed significant interaction between the local and systemic inflammatory response after severe trauma in small animal models. The purpose of this study was to establish a new combined trauma model in pigs to investigate fracture-associated local inflammation and gain information about the early inflammatory stages after polytrauma. Material and Methods. Combined trauma consisted of tibial fracture, lung contusion, liver laceration, and controlled hemorrhage. Animals were mechanically ventilated and under ICU-monitoring for 48 h. Blood and fracture hematoma samples were collected during the time course of the study. Local and systemic levels of serum cytokines and diverse alarmins were measured by ELISA kit. Results. A statistical significant difference in the systemic serum values of IL-6 and HMGB1 was observed when compared to the sham. Moreover, there was a statistical significant difference in the serum values of the fracture hematoma of IL-6, IL-8, IL-10, and HMGB1 when compared to the systemic inflammatory response. However a decrease of local proinflammatory concentrations was observed while anti-inflammatory mediators increased. Conclusion. Our data showed a time-dependent activation of the local and systemic inflammatory response. Indeed it is the first study focusing on the local and systemic inflammatory response to multiple-trauma in a large animal model.

  15. Challenging the Pathophysiologic Connection between Subdural Hematoma, Retinal Hemorrhage and Shaken Baby Syndrome

    Directory of Open Access Journals (Sweden)

    Gabaeff, Steven C

    2011-05-01

    Full Text Available Child abuse experts use diagnostic findings of subdural hematoma and retinal hemorrhages as near-pathognomonic findings to diagnose shaken baby syndrome. This article reviews the origin of this link and casts serious doubt on the specificity of the pathophysiologic connection. The forces required to cause brain injury were derived from an experiment of high velocity impacts on monkeys, that generated forces far above those which might occur with a shaking mechanism. These forces, if present, would invariably cause neck trauma, which is conspicuously absent in most babies allegedly injured by shaking. Subdural hematoma may also be the result of common birth trauma, complicated by prenatal vitamin D deficiency, which also contributes to the appearance of long bone fractures commonly associated with child abuse. Retinal hemorrhage is a non-specific finding that occurs with many causes of increased intracranial pressure, including infection and hypoxic brain injury. The evidence challenging these connections should prompt emergency physicians and others who care for children to consider a broad differential diagnosis before settling on occult shaking as the de-facto cause. While childhood non-accidental trauma is certainly a serious problem, the wide exposure of this information may have the potential to exonerate some innocent care-givers who have been convicted, or may be accused, of child abuse.

    Babi, Marc-Alain; James, Michael L.

    2017-01-01

    Spontaneous intracerebral hemorrhage (SICH) is the most lethal type of stroke. Half of these deaths occur within the acute phase. Frequently observed deterioration during the acute phase is often due to rebleeding or peri-hematomal expansion. The exact pathogenesis that leads to rebleeding or peri-hemorrhagic edema remains under much controversy. Numerous trials have investigated potential predictor of peri-hemorrhagic edema formation or rebleeding but have yet to come with consistent results. Unfortunately, almost all of the “classical” approaches have failed to show a significant impact in regard of significant clinical outcome in randomized clinical trials. Current treatment strategies may remain “double-edged swords,” for inherent reasons to the pathophysiology of sICH. Therefore, the right balance and possibly the combination of current accepted strategies as well as the evaluation of future approaches seem urgent. This article reviews the role of disturbed autoregulation following SICH, surgical and non-surgical approaches in management of SICH, peri-hematoma edema, peri-hematoma expansion, and future therapeutic trends.

    Full Text Available Uma série de 23 pacientes com hematoma espontâneo de cerebelo é analisada retrospectivamente, mostrando que: todos apresentavam algum grau de diminuição do nível de consciência e cefaléia; 12 apresentavam déficits motores dentre os sinais clínicos mais importantes. Dos antecedentes patológicos destacam-se hipertensão arterial (69,5% e diabetes (34%, havendo associação de ambos em 30% dos casos. Dos aspectos da tomografia computadorizada (TC mais relevantes a dilatação ventricular aguda, encontrada em 69,5% dos pacientes, associada ou não a presença de sangue intraventricular, é considerada sinal de mau prognóstico, indicando por si só terapêutica de urgência. A melhor abordagem cirúrgica para a maioria desses casos é a drenagem ventricular externa de urgência, reservando a craniectomia da fossa posterior para esvaziamento do hematoma para casos específicos. A mortalidade e a morbidade desta patologia é alta; porém, pela TC o diagnóstico se tornou mais rápido e eficiente. Os pacientes desta série puderam beneficiar-se deste procedimento, como se verifica quando comparados a pacientes de outras séries, diagnosticados por outros métodos.

    Full Text Available Background: Symptomatic arachnoiditis after posterior fossa surgical procedures such as decompression of Chiari malformation is a possible complication. Clinical presentation is generally insidious and delayed by months or years. It causes disturbances in the normal flow of cerebrospinal fluid and enlargement of a syrinx cavity in the upper spinal cord. Surgical de-tethering has favorable results with progressive collapse of the syrinx and relief of the associated symptoms. Case Description: A 30-year-old male with Chiari malformation type I was treated by performing posterior fossa bone decompression, dura opening and closure with a suturable bovine pericardium dural graft. Postoperative period was uneventful until the fifth day in which the patient suffered intense headache and progressive loose of consciousness caused by an acute posterior fossa epidural hematoma. It was quickly removed with complete clinical recovering. One year later, the patient experienced progressive worsened of his symptoms. Upper spinal cord tethering was diagnosed and a new surgery for debridement was required. Conclusions: The epidural hematoma compressing the dural graft against the neural structures contributes to the upper spinal cord tethering and represents a nondescribed cause of postoperative fibrosis, adhesion formation, and subsequent recurrent hindbrain compression.

    The purpose of this study was to evaluate multidetector row CT (MDCT) angiographic findings and their clinical significance for contrast extravasation into a spontaneous intracerebral hematoma (ICH). MDCT angiographic studies and clinical records of 115 patients with spontaneous ICH were retrospectively reviewed. Cases were divided into two groups according to the presence or absence of contrast extravasation. The cases in the two groups were compared to determine the differences in radiological and clinical findings. The contrast extravasation group was divided into two subgroups according to radiological findings as follows: single or multiple dot-like contrast extravasation (Type A) and beaded-tubular (with or without dot-like extravasation) contrast extravasation (Type B). Contrast extravasation was seen in 38 patients (33%). It was associated with a larger hematoma volume, more frequent intraventricular hemorrhage (IVH) and subarachnoid hemorrhage (SAH), a shorter time interval from onset to the time of the CT scan, lower Glasgow coma scale (GCS), and a higher mortality rate. Type A and B contrast extravasation were observed in 16 (42%) and 22 (58%) patients, respectively. The rate of IVH and the clinical outcome of patients with Type B showed a significant correlation. Two types of contrast extravasation into an ICH show a significant difference in the rate of IVH and in clinical outcome. Detecting the presence of contrast extravasation and classifying them according to the morphologic patterns are important in predicting a prognosis.

    In 1995, the Federal government initiated Operation Restore Trust to increase enforcement of fraud and abuse regulations in Medicare and Medicaid programs. With the success of the original initiative, the government is expanding the project to additional states and program areas. The initial scrutiny of home health agencies, nursing homes, hospice care, and durable medical equipment is being expanded to managed care plans and acute care hospitals with an eye toward DRG creep. To manage this increased enforcement activity, healthcare organizations should institute comprehensive corporate compliance programs. Such programs should provide a framework that delineates responsibilities and provides a systematic means to resolve issues in a timely manner.

    The non-traumatic spinal epidural hematoma (NTSEH) is a rare entity that can be the cause of an acute spinal compression syndrome. the objective of this review is to identify the characteristics by MRI and NTSEH and to analyze the factors that influence in its prognosis. In the years 1994 and 1999, 12 patients with NTSEH have been diagnosed in our hospital, and a MRI was performed during the acute phase. the characteristics of the lesions have been analyzed by MRI, with special emphasis on the topographic data and resonance signal and the factors that can influence in the clinical prognosis of the patients. Initially, all of the patients presented pain in the cervical dorsal or interscapular site, followed by a sensitive-motor deficit picture. The MRI showed a lesion of expansive character and posterior epidural location in every case that would produce varying degrees of compression on the spinal cord. The NTSEH should be considered as one of the causes of acute spinal cord compression. The clinical association of intense cervical, dorsal or interscapular pain followed by a sensomotor deficit picture should lead to the suspicion of this entity, that would require an immediate examination with MRI to verify its diagnosis. Both the clinical manifestations as well as the characteristics observed by MRI of the NTSEH have a prognostic value and determine the therapeutic decision. (Author) 34 refs.

    Traumatic retropharyngeal hematoma is a rare condition and may be lethal in some cases.In patients with this condition, the absence of a vertebral fracture or a major vascular injury is extremely rare.We present the case of a 92-year-old man who hit his forehead by slipping on the floor in his house.He had no symptoms at the time; however, he experienced throat pain and dyspnea at 6 hours after the injury.On arrival, he complained of severe dyspnea; therefore, an emergency endotracheal intubation was performed.A lateral neck roentgenogram after intubation showed dilatation of the retropharyngeal and retrotracheal space and no evidence of a cervical vertebral fracture.Cer-vical computed tomography (CT) with contrast medium re-vealed a massive hematoma extending from the retropharyngeal to the superior mediastinal space but no evidence of contrast medium extravasation or a vertebral fracture.However, sagittal magnetic resonance imaging (MRI) revealed an anterior longitudinal ligament (C levels)injury.We determined that the cause of the hematoma was an anterior longitudinal ligament injury and a minor vascu-lar injury around the injured ligament.Therefore, we recom-mend that patients with retropharyngeal hematoma undergo sagittal cervical MRI when roentgehography and CT reveal no evidence of injury.

    The objective of this porcine study was to evaluate the effect of closed incision management with negative pressure wound therapy (CIM) on hematoma/seroma formation, fluid removal into the CIM canister, and involvement of the lymphatic system. In each swine (n = 8), two sets of ventral contralateral subcutaneous dead spaces with overlying sutured incisions were created. Stable isotope-labeled nanospheres were introduced into each subcutaneous dead space. Each contralateral incision was assigned to CIM (continuous -125 mmHg negative pressure) and control (semipermeable film dressing), respectively. Following 4 days of therapy, hematoma/seroma was weighed, total fluid volume in canisters was measured, five pre-identified lymph nodes were harvested, and five key organs were biopsied. There was 25 ± 8 g (standard error [SE]) (63%) less hematoma/seroma in CIM sites compared to control sites (p = 0.002), without any fluid collection in the CIM canister. In lymph nodes, there were ∼60 μg (∼50%) more 30- and 50-nm nanospheres from CIM sites than from control sites (p = 0.04 and 0.05, respectively). There was significantly greater nanosphere incidence from CIM sites than from control sites in lungs, liver, and spleen (p CIM significantly decreased hematoma/seroma levels without fluid collection in the canister, which may be explained by increased lymph clearance.

    Full Text Available Introduction & Objective: Among all of the neurologic diseases in adult life, the cerebrovascular disease (CVD is the most common and important ones. Intracerebral hemorrhage (ICH in basal ganglia (BG is one of the common and major types of CVD. The relations between clot size and mortality rate, in different parts of the brain, has been addressed by several researchers. It is unclear whether such a relationship is in BG. Therefore this study was designed to find a formula that predicts outcome of hemorrhage based on clot size in BG.Materials & Methods: This descriptive-comparative study that was carried out prospectively, conducted on all 63 patients who admitted to the hospital during one year, with definite diagnosis of ICH in BG. After urgent CT scanning, the size of hematoma was determined by scan images. Routine treatment was uniform for all patients. Focal signs and consciousness state were assessed in the first and last days of admission. The data were analyzed using descriptive statistics, frequency tables and chi-square and T- test. Results: 33% of patients died. Hematoma size in 70% of them was larger than 5cm and in other 30% smaller. None of the hematoma with less than 4cm size was fatal. In patients with clots of 5cm or larger, the mortality was 100%. Conclusion: The results indicated that, there was meaningful relationship between hematoma size and mortality, in BG hemorrhages. So the clot size can be used as a factor in predicting hemorrhage outcome in BG.

    Full Text Available Abstract Introduction Axillary artery injury in the shoulder region following blunt trauma without association with either shoulder dislocation or fracture of the humeral neck has been previously reported. Axillary artery injury might also be accompanied with brachial plexus injury. However, delayed onset of brachial plexus palsy caused by a compressive hematoma associated with axillary injury after blunt trauma in the shoulder region has been rarely reported. In previous reports, this condition only occurred in old patients with sclerotic vessels. We present a case of a young patient who suffered axillary artery injury associated with brachial plexus palsy that occurred tardily due to compressive hematoma after blunt trauma in the shoulder region without association of either shoulder dislocation or humeral neck fracture. Case presentation A 16-year-old male injured his right shoulder in a motorbike accident. On initial physical evaluation, the pulses on the radial and ulnar arteries in the affected arm were palpable. Paralysis developed later from 2 days after the injury. Functions in the right arm became significantly impaired. Angiography showed complete occlusion of the axillary artery. Magnetic resonance imaging demonstrated a mass measuring 4 × 5 cm that was suspected to be a hematoma compressing the brachial plexus in a space between the subscapular muscle and the pectoralis minor muscle. Surgery was performed on the third day after injury. In intraoperative observations, the axillary artery was occluded with thrombus along 5 cm; a subscapular artery was ruptured; the brachial plexus was compressed by the hematoma. After evacuation of the hematoma, neurolysis of the brachial plexus, and revascularization of the axillary artery, the patient had an excellent functional recovery of the affected upper limb, postoperatively. Conclusion Surgeons should be aware that axillary artery injuries may even occur in young people after severe blunt

    To assess the efficacy of magnetic resonance (MR) imaging for detection of associated brain injuries in cases of extradural hematoma (EDH), 32 patients with EDH were examined by MR. CT detected associated lesion in eleven patients (34%), while MR detected them in 24 patients (75%). MR is more sensitive than CT in detecting associated lesions, especially when T2-weighted imaging is used. Non-hemorrhagic contusions adjacent to EDH and near the cranial base were well shown by MR; however, they tended to be missed by CT. EEG findings were clearly related to abnormalities detected by MR. Coupling between functional change and organic change was confirmed. The improved detection and anatomic localization of associated brain injuries by MR should allow more accurate assessment of brain injuries, and sophisticated management of EDH patient. The authors also discuss the cardiorespiratory monitoring and support during MRI examination in critically ill patients. (author).

    With the increase in the number of patients undergoing warfarin therapy, reports of complications due to such therapy have become frequent. Although upper airway obstruction secondary to bleeding resulting from warfarin therapy is rare, it is a life-threatening complication because of the risk of airway obstruction. Only one previous case of hematoma of the epiglottis and arytenoids has been reported. We here in report a case of an 83-year-old woman on warfarin therapy who presented with a sore throat. On flexible nasoendoscopy, edema of the epiglottis and bilateral arytenoids with a red and purple hue were observed. The left true vocal cord was erythematous, but the airway was adequately maintained. The PT-INR of the patient was 10. She was managed conservatively and had a good course.

    Objective: To study the influence of operative timing on the prognosis of patients with acute subdural hematoma (ASDH) in order to provide theoretical basis for clinical treatment.Methods: The clinical data of 202 patients with ASDH undergoing operations were collected, and the mortalities and functional survival rates were analyzed 2, 4, 6, and 8 hours after injury.Results: No significant difference was found in mortalities and functional survival rates at different operative timings. However, there was a clear trend that the shorter the operative timing was, the lower the mortality and the higher functional survival rate were. In addition, the mean time from injury to operation of non-survivors was significantly longer than that of survivors.Conclusions: Operative timing has potential influences on the prognosis of patients with ASDH. Surgical evacuation of ASDH should be performed as soon as possible once the operation indication emerges.

    Full Text Available Electroconvulsive therapy (ECT is commonly used in the management of medication nonresponsive depressive disorder, with proven efficacy in psychiatric practice since many decades. A rare complication of intracranial bleed following this therapeutic procedure has been reported in sporadic case reports in the English literature. We report a case of such a complication in a 42-year-old male, a known case of nonorganic medication nonresponsive depressive disorder for the last two years who required ECT application. Presenting symptoms included altered mental state, urinary incontinence, and repeated episodes of vomiting; following ECT procedure with magnetic resonance imaging (MRI of the brain suggestive of bilateral acute subdural hematoma. Despite the view that it may be used in neurological conditions without raised intracranial tension, it will be worthwhile to be vigilant during post-ECT recovery for any emergent complications.

    Full Text Available BACKGROUND: Breast hematomas are common after traumas, surgeries, or contusions. They are rarely spontaneous, but they can occur spontaneously in patients with hematologic disease or with coagulation disorders. MATERIAL AND METHODS: The authors report a clinical case of a 48-year-old female with a 27-year history of paroxysmal nocturnal hemoglobinuria who underwent mammography screening because of a painless palpable moveable node in the upper inner quadrant of the right breast. RESULTS: Mammography showed a partially defined heterogeneous node of 35 mm without microcalcifications in the upper inner quadrant of the right breast which, associated with the clinical features, seemed to be an hematoma. Further mammography and ultrasound after 45 days showed retrocession of the lesion, and another mammography obtained after 60 days was normal. Seventy-five days after the first episode, the patient complained of another node with a skin bruise in the upper outer quadrant of the same breast, which seemed to be a recurrent hematoma. Two months later the mammography obtained was normal. CONCLUSION: Breast hematoma must be thought of as a differential diagnosis for a breast node, regardless of previous trauma or hematologic disorders.OBJETIVO: Os hematomas de mama são comuns após traumatismo, cirurgias ou contusões. Raramente são espontâneos, podendo ocorrer em pacientes com doença hematológica ou outras doenças associadas a distúrbios da coagulação sangüínea.

    Full Text Available PURPOSE: The authors present a prospective study on 10 patients with stereotactic infusion of tissue plasminogen activator (rtPA intraparenchimal hemorrhage. METHODS: Between 1999 and 2000, 10 patients with deep seated hematomas in the basal ganglia were selected for stereotactic infusion of rtPA and spontaneous clot drainage. RESULTS: All cases had about 80% reduction of the hematoma volume in the CT scan at the third day. The intracranial pressure was normalized by the third day too. There were no local or systemic complications with the use of this trombolitic. The results were shown by the Glasgow Outcome Scale with six patients in V, three in IV and one in III after 3 months. CONCLUSION: Early treatment and drainage with minimally invasive neurosurgery , can make these patients with deep-seated hematomas recover the consciousness and they can be rehabilitated earlier avoiding secondary complications.OBJETIVO: Estudo prospectivo em 10 pacientes com infusão de trombolítico (rtPA dentro do hematoma cerebral profundo supratentorial e drenagem estereotáxica. MÉTODO: Entre 1999 e 2000 10 pacientes com hematomas de profundidade foram selecionados para infusão de rtPA e drenagem do coágulo espontânea. RESULTADO: Todos os casos obtiveram 80% de redução do volume do hematoma medidos por TC no terceiro dia. A pressão intracraniana estava normalizada no terceiro dia. Não houve complicações locais ou sistêmicas relacionadas com o uso deste trombolítico. Os resultados comparados foram mostrados pela Escala de Prognóstico de Glasgow com 6 pacientes em GrauV, 3 pacientes em Grau IV e 1 paciente em Grau III após três meses. CONCLUSÃO: Tratamento precoce e drenagem com técnica neurocirúrgica minimamente invasiva pode fazer estes pacientes terem uma recuperação da consciência mais rápida e assim serem reabilitados mais precocemente evitando complicações secundárias.

    2016-01-01

    Acute traumatic subdural hematomas (SDHs) are very common. These hematomas are usually neurosurgical emergencies, although conservative therapy is indicated in certain cases. SDH can increase intracranial pressure (ICP) and compress or stretch the brainstem. Lately, it has been recognized that increased ICP can lead to hemodynamic instability and bradycardia. Bradycardia can be an early warning sign in many neurosurgical conditions. We observed bradycardia in serial cases of the patient witho...

    Full Text Available Background. While the benefits of using acellular dermal matrices (ADMs in breast reconstruction are well described, their use has been associated with additional complications. The purpose of this study was to determine if ADM thickness affects complications in breast reconstruction. Methods. A retrospective chart review was performed including all tissue expander based breast reconstructions with AlloDerm (LifeCell, Branchburg, NJ over 4 years. We evaluated preoperative characteristics and assessed postoperative complications including seroma, hematoma, infection, skin necrosis, and need for reintervention. We reviewed ADM thickness and time to Jackson-Pratt (JP drain removal. Results. Fifty-five patients underwent 77 ADM-associated tissue expander based breast reconstructions, with average age of 48.1 years and average BMI of 25.9. Average ADM thickness was 1.21 mm. We found higher complication rates in the thick ADM group. Significant associations were found between smokers and skin necrosis (p<0.0001 and seroma and prolonged JP drainage (p=0.0004; radiated reconstructed breasts were more likely to suffer infections (p=0.0085, and elevated BMI is a significant predictor for increased infection rate (p=0.0037. Conclusion. We found a trend toward increased complication rates with thicker ADMs. In the future, larger prospective studies evaluating thickness may provide more information.

    Full Text Available Cerebellar hemorrhage following a spinal surgery is extremely rare; however, considering the localization, it can cause major clinical manifestations. While it is considered that these types of bleedings occur secondary to a venous infarct, the pathogenesis is still unclear. A 57-year-old male patient who underwent a laminectomy by exposing T12-L5 and had pedicle screws placed for ankylosing spondylitis developed a CSF leak due to a 2 mm dural tear. A hemorrhage with parallel streaks on the left cerebellar hemisphere was seen in CT scan, and a thin subdural hematoma at right frontotemporal region was seen on cranial MRI, performed after the patient developed intense headache, nausea, vomiting, and stiff neck in the early postoperative period. In this paper, a case of cerebellar and subdural hematomas following a spinal surgery is discussed with its clinical and radiologic findings.

    We herein present a case of acquired hemophilia A with a normal activated partial thromboplastin (aPTT), intramuscular hematoma and cerebral hemorrhage occurring in a 73-year-old man. The patient visited our emergency department with gait disturbance, pain and swelling in his right leg. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed intramuscular hematoma and intracranial hemorrhage. The results of initial coagulation studies were normal, but repeated coagulation studies revealed an isolated prolongation of the aPTT. Additional laboratory tests confirmed the diagnosis of acquired hemophilia A. If the initial aPTT is normal, we should therefore repeat the aPTT and also perform other coagulation studies including a mixing study, factor VIII level and inhibitor, to investigate the underlying diseases in elderly patients with spontaneous hemorrhaging of unknown etiology.

    The prognosis for patients with traumatic brain injury (TBI) with subdural hematoma (SDH) remains poor. In accordance with an increasing elderly population, the incidence of geriatric TBI with SDH is rising. An important contributor to the neurological injury associated with SDH is the ischemic damage which is caused by raised intracranial pressure (ICP) producing impaired cerebral perfusion. To control intracranial hypertension, the current management consists of hematoma evacuation with or without decompressive craniotomy. This removal of the SDH results in the immediate reversal of global ischemia accompanied by an abrupt reduction of mass lesion and an ensuing reperfusion injury. Experimental models can play a critical role in improving our understanding of the underlying pathophysiology and in exploring potential treatments for patients with SDH. In this review, we describe the epidemiology, pathophysiology and clinical background of SDH.

    Pituitary apoplexy is a clinical syndrome occurring as a consequence of fulminant expansion of pituitary tumor due to massive infarction, necrosis, and hemorrhage. Its association with head injury is rare and only few reports are available. Shear forces on stalk and arterial vasospasm have been proposed to be the possible reasons. The clinical picture is characterized by sudden onset headache, visual symptoms, multiple cranial nerves involvement, meningismus, altered mental status, and hormonal dysfunction. Transsphenoidal decompression is the standard treatment but suprasellar and widespread extension of hematoma may need intracranial approach. We are reporting a rare association of head injury with pituitary apoplexy, where endonasal surgery proved to be a simple useful approach to evacuate contiguous intra-cerebral hematoma with excision of apoplectic pituitary adenoma.

    Extracorporeal shockwave lithotripsy (SWL) is a commonly used technique for treating urinary calculi. Although noninvasive, highly effective, and widely accepted, SWL is not without complications. Next to fragmenting the calculi, the surrounding tissue is damaged, which can result in renal hematoma, a well-described complication. In most cases, the collateral tissue damage is mild and resolves with conservative treatment. However, rarely, severe complications may arise. Here we present a case of a 46-year-old male who developed a massive hematoma, both subcapsular and retroperitoneal, after a third consecutive SWL session, resulting in hypovolemic shock. Different probable causes are proposed, of which one cause, the length of the interval between SWL sessions, is not yet studied properly. Probably, short intervals keep the damaged tissue from healing sufficiently, as proposed in our case. Possibly, life-threatening situations can be avoided if more evidence-based guidelines are available.

    Several recent global traumatic brain injury (TBI) initiatives rely on practice variation in diagnostic and treatment methods to answer effectiveness questions. One of these scientific dilemmas, the surgical management of the traumatic acute subdural hematoma (ASDH) might be variable among countries, among centers within countries, and even among neurosurgeons within a center, and hence be amenable for a comparative effectiveness study. The aim of our questionnaire, therefore, was to explore variations in treatment for ASDH among neurosurgeons in similar centers in a densely populated geographical area. An online questionnaire, involving treatment decisions on six case vignettes of ASDH, was sent to 93 neurosurgeons in The Netherlands and Belgium. Clinical and radiological variables differed per case. Sixty neurosurgeons filled out the questionnaire (response rate 65%). For case vignettes with severe TBI and an ASDH, there was a modest variation in the decision to evacuate the hematoma and a large variation in the decision to combine the evacuation with a decompressive craniectomy. The main reasons for operating were "neurological condition" and "mass effect." For ASDH and mild/moderate TBI, there was large variation in the decision of whether to operate or not, whereas "hematoma size" was the predominant motivation for surgery. Significant inter-center variation for the decision to evacuate the hematoma was observed (p = 0.01). Most pronounced was that 1 out of 7 (14%) neurosurgeons in one region chose a surgical strategy compared with 9 out of 10 (90%) in another region for the same scenario. In conclusion, variation exists in the neurosurgical management of TBI within an otherwise homogeneous setting. This variation supports the methodology of the international Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) initiative, and shaped the Dutch Neurotraumatology Quality Registry (Net-QuRe) initiative.

    Full Text Available Abstract Background We present a report of a blunt-trauma patient who developed an atypical extrapleural hematoma with hemodynamic instability following a dislocation fracture of the first lumbar vertebra. We successfully treated her with arterial embolization (AE of the lumbar and intercostal arteries. Case report The patient, a 74-year-old woman, was injured in a traffic accident. At the scene of the accident, she was found to be alert, and her hemodynamic condition was stable. She arrived at our hospital complaining of lumbago. A thoracoabdominal computed tomography (CT scan with contrast enhancement showed a dislocation fracture of the first lumbar vertebra along with paravertebral and retroperitoneal hematomas. Therefore, we managed the patient conservatively with bed rest. However, 3 h after admission, her blood pressure suddenly decreased. A repeated thoracoabdominal CT scan showed enlargement of the right retroperitoneal hematoma with extravasation of the contrast medium into the right extrapleural space. Angiography was immediately performed, showing extravasation of the contrast media from the right intercostal (Th12 and lumbar arteries (L1. After arterial embolization (AE with gelatin-sponge particles, extravasation of the contrast medium ceased, and the patient's hemodynamic condition stabilized without massive fluid resuscitation. Conclusion The extrapleural hematoma reduced in size after AE, and almost disappeared on the 14th day of hospitalization. The lumbar spinal fracture was successfully repaired on day 16, and the patient was kept in the hospital to recuperate. We believe that AE is effective for the management of intractable bleeding following fractures of the spine.

    Although ultrasound (US) guidance for venous access is becoming the “standard of care” for preventing access site complications, its feasibility for arterial access has not been fully investigated, especially in the neuro-interventional population. We conducted the first prospective cohort study on US-guided femoral artery access during neuro-interventional procedure. This study included 64 consecutive patients who underwent US-guided femoral artery access through 66 arterial access sites for diagnostic and/or neuro-interventional purposes. The number of attempts required for both the sheath insertion and the success of anterior wall puncture were recorded. In addition, the occurrence of major complications and hematoma formation on the arterial access site examined by US were statistically analyzed. The median number of attempts was 1 (1–2) and first-pass success rate was 63.6%. Anterior wall puncture was achieved in 98.5%. In one case (1.5%), a pseudoaneurysm was observed. In all cases, US clearly depicted a common femoral artery (CFA) and its bifurcation. Post-procedural hematoma was detected in 13 cases (19.7%), most of which were “tiny” or “moderate” in size. Low body mass index and antiplatelet therapy were the independent risk factors for access site hematoma. The US-guided CFA access was feasible even in neuro-interventional procedure. The method was particularly helpful in the patients with un-palpable pulsation of femoral arteries. To prevent arterial access site hematoma, special care should be taken in patients with low body mass index and who are on antiplatelet therapy. PMID:27194178

    Full Text Available Background. Currently, miscarriage is considered to be a multietiological disorder with trombofilic violations and hormone deficiency as the leading factors. Despite the achievements in treatment of miscarriage, the frequency of preterm termination of the wanted pregnancies is still high and the number of perinatal losses is significant. Therefore, pathogenetically based therapy, safe for the foetus, is very important in management of pregnancy interruption in the first trimester. A proper drugs administration provides optimal concentration of active ingredients and fast action. The aim is to improve effectiveness of the early threatened abortion treatment in cases of subchorionic hematoma (SCH by combination of sublingual natural micronized progesterone and tranexamic acid Objective. We examined 50 pregnant women with early threatened abortion with SCH. We studied system of haemostasis, basic hormonal markers and ultrasound criteria of threatened abortion. We compared efficacy of treatment between traditional (supportive therapy (sedation, spasmolytic, haemostatic drug and combination of supportive therapy in combination with tranexamic acid and natural micronized progesterone. Results. The result of lab tests showed minimal signs of hypercoagulation, hyperfibrinogenemia and platelet hyperactivity, a significant β-hCG level decrease and approximate decrease in progesterone and free estriol production. Sonographic examination showed presents of local myometrial hypertonus, deformation of fertilized egg, hypoplasia of chorion, low location of fertilized ovum, retarded growth of CRL.The research proved that combined administration of sublingual micronized progesterone and tranexamic acid for the treatment of threatened abortion with SCH has more significant positive effect for pregnancy maintenance due to clinical, biochemical, hormonal and ultrasound results if compared with the group which underwent supportive therapy. Conclusions. Complex

    Full Text Available Considerando o estado neurológico imediatamente antes da operação como a variável miais fidedigna para antecipação do prognóstico dos hematomas extradurais, os autores realizaram estudo radiológico comparativo de 129 pacientes operados por esta patologia. Desta amostra, 78 casos se encontravam em coma (Grupo I e 51 eram não comatosos (Grupo II. No grupo I, os 30 casos investigados pré-operatoriamente com tomografia tiveram 23,3% de mortalidade e 50% de bons resultados; dos 31 casos submetidos a angiografia, 48,3% faleceram e 38,7% tiveram bons resultados; 17 casos foram operados pela radiografia simples de crânio e exame neurológico, com 47% de mortalidade e 35,2% de bons resultados. A presença de fratura de crânio e a densidade tomográfica do hematoma não interferiram nos resultados. A presença de lesão associada intracraniana aumentou a mortalidade e diminuiu a quantidade de bons resultados tanto no Grupo I quanto no Grupo II. A localização frontal do hematoma foi associada a elevada mortalidade (52,6% no grupo comatoso, por estarem todos os pacientes entre 3 a 5 pontos na Escala de Glasgow e seis deles por apresentarem lesões associadas intracranianas únicas ou múltiplas.

    The purpose of this study was to demonstrate corticospinal tract compression that was due to a hematoma by using diffusion tensor tractography (DTT) and functional MRI (fMRI) in a patient with an intracerebral hemorrhage (ICH). A 23-year-old right-handed woman presented with severe paralysis of her right extremities at the onset of a spontaneous ICH. Over the first three days from onset, the motor function of the affected upper and lower extremities rapidly recovered to the extent that she was able to overcome applied resistance to the affected limbs, and her limbs regained normal function 3 weeks after onset. The tract of the right hemisphere originated from the primary sensori-motor cortex (SM1) and it passed through the known corticospinal tract pathway. However, the tract of the left hemisphere was similar to that of the right hemisphere except that it was displaced to the antero-medial side by the hematoma at the cerebral peduncle. Only the contralateral SM1 area centered on the precentral knob was activated during affected (right) or unaffected (left) hand movements, respectively. In conclusion, fMRI and DTT demonstrated a corticospinal tract compression due to hematoma in this patient. We conclude that the combined use of these two modalities appears to improve the accuracy of investigating the state of the corticospinal tract. PMID:16502496

    Background Subdural hematoma (SDH) is a common complication of spontaneous intracranial hypotension (SIH).To date,the management of SDH caused by SIH remains controversial.In this paper,we reviewed the clinical course of SDH in patients with SIH,and discuss the underlying mechanism and attributing factors for rapid resolution of subdural hematomas after epidural blood patch (EBP) surgery.Methods We retrospectively reviewed a cohort of seventy-eight SIH patients diagnosed and treated with targeted EBP in our neurology center.Patients who received early CT/MRI follow-up after EBP operation were included.Results A series of four cases of SIH complicated with SDHs were evaluated.Early follow-up neuroimages of these patients revealed that SDHs could be partially or totally absorbed just two to four days after targeted epidural blood patch treatment.Conclusion Targeted epidural blood patch can result in rapid hematoma regression and good recovery in some patients with a combination of SDH and SIH.

  8. Shear Acceleration in Expanding Flows

    Rieger, F M

    2016-01-01

    Shear flows are naturally expected to occur in astrophysical environments and potential sites of continuous non-thermal Fermi-type particle acceleration. Here we investigate the efficiency of expanding relativistic outflows to facilitate the acceleration of energetic charged particles to higher energies. To this end, the gradual shear acceleration coefficient is derived based on an analytical treatment. The results are applied to the context of the relativistic jets of active galactic nuclei. The inferred acceleration timescale is investigated for a variety of conical flow profiles (i.e., power law, Gaussian, Fermi-Dirac) and compared to the relevant radiative and non-radiative loss timescales. The results exemplify that relativistic shear flows are capable of boosting cosmic-rays to extreme energies. Efficient electron acceleration, on the other hand, requires weak magnetic fields and may thus be accompanied by a delayed onset of particle energization and affect the overall jet appearance (e.g., core, ridge ...

    Objectives: To systematically review the literature on dating subdural hematomas (SDHs) on CT and MRI scans. Methods: We performed a systematic review in MEDLINE, EMBASE and Cochrane to search for articles that described the appearance of SDHs on CT or MRI in relation to time between trauma and scanning. Two researchers independently screened the articles, assessed methodological quality and performed data extraction. Medians with interquartile ranges were calculated. Differences were tested with a Mann–Whitney U or Kruskal–Wallis H test. Results: We included 22 studies describing 973 SDHs on CT and 4 studies describing 83 SDHs on MRI. Data from 17 studies (413 SDHs) could be pooled. There were significant differences between time intervals for the different densities on CT (p < 0.001). Time interval differed significantly between children and adults for iso- and hypodensity (p = 0.000) and hyperdensity (p = 0.046). Time interval did not differ significantly between abused and non-abused children. On MRI, time intervals for different signal intensities on T1 and T2 did not differ significantly (p = 0.108 and p = 0.194, respectively). Conclusions: Most time intervals of the different appearances of SDHs on CT and MRI are broad and overlapping. Therefore CT or MRI findings cannot be used to accurately date SDHs.

    Objective: To evaluate the result of diagnosis and treatment of intracranial hematoma and multiple injuries caused by road traffic accidents. Methods: Twenty-eight patients, aged from 1 to 14 years, receiving craniotomy and other surgical treatments were retrospectively reviewed. Results: Among the 28 cases, 23 cured with the recovery rate of 82.3%, 2 had a sequel of moderate disability, and 3 died from severe brain injury, hemorrhagic shock, and other visceral complications. The clinical sympotoms and signs were severe and perplexing. The major characters included: severe head injury, usually combined by multiple injuries, and easy of access to missed diagnosis and misdiagnosis. Conclusions: The occurrence of infection is high after traffic accidents as a result of depression of humoral and cellular immunity, long-term bed rest, and fractures of limbs. Hence, on the basis of maintaining vital signs, the management of primary wound is essential to reduce infection and underlying death. In addition to the management of brain injury, concurrent injuries should also be highlighted so as to reach a good result for their patients.

    The purpose of this study was to describe the CT findings and clinical outcomes of nineteen patients with acute intramural hematoma (IMH) of the ascending aorta. Six patients underwent surgery on the emergency basis (3 patients) due to cardiac tamponade (n=2) and dilated aorta (n=1), and on the elective basis (3 patients) due to patent and enlarging false lumen. Among the 13 patients with medical management, four patients died from complications of IMH during the follow-up period (2 days-2.5 years). Transition to aortic dissection or enlargement of an intimal tear was noted in 5 patients (31%) in 1 to 6 weeks after onset. Three patients died of causes not related to IMH. Six patients had been alive 2 to 9 years after onset. Retrospective review revealed 10 patients (53%) as possible surgical candidates, and the other 9 patients as medically treated patients in the long-term follow-up. The surgical group showed cardiac tamponade or shock in 6 patients on admission and had pericardial effusion in all the patients on the initial CT scan. In the patients with acute IMH of the ascending aorta, surgery should be considered for severe clinical symptoms, pericardial effusion and large size of the ascending aorta (more than 4 cm) on CT scan, and for converting to a typical type A aortic dissection. CT scan had a major role in making an early diagnosis, in depicting a dangerous sign, and in monitoring its progression or resolution of IMH. (author)

    Full Text Available Background: To analyze the characteristics of the patients with diagnosis of spontaneous retroperitoneal hematoma associated with anticoagulation therapy and antiplatet therapy. Methods: From January 2006 to March 2013, 9 patients (6 from Haseki Training and Research Hospital - Urology Department and 3 from Istanbul Medical Faculty - Gynecology and Obstetric Department were included in the study. Patients charts including sex, age, comorbidities, main complaint, and medication intake were examined. Also initial hemoglobin level, initial International Normalized Ratio level, red blood cells and fresh frozen plasma units transfused were evaluated. Results: Median age was 60 year-old. Abdominal pain and flank pain were common symptoms. Eight patients were taking only anticoagulation therapy, 2 only antiplatet therapy and 1 both anticoagulation and antiplatet therapy. Median initial hemoglobin value was 9,0 g/dL and median International Normalized Ratio level was 3.2 Patients were evaluated by abdominal ultrasonography or abdominal computer tomography. Seven patients were treated conservatively. Only one patient died because of septic shock with a mortality ratio of 11%. Conclusion: Despite benefits of anticoagulation and antiplatet theraphy these agents have serious side-affects as retroperitoneal hemorrhage in elderly patients taking multi-drug medication.

    AIM: To retrospectively analyze the pathogenesis, clinical characteristics, treatment and prognostic characteristics in patients with traumatic basal ganglia hematomas (TBGH).METHODS: A retrospective analysis of the clinical data was performed in 40 patients with TBGH who were selected from 1 250 patients with closed brain injury, who admitted to the Department of Neurosurgery of Shangqiu First People's Hospital from January 1990 to January 2004. The pathogenesis, clinical characteristics and signs, results of radiological examination, treatment and prognostic characteristics were analyzed. The patients all had definite history of brain injury, manifested by neurological functional disturbance to different extent after brain injury, and basal ganglia hemorrhage was identified by CT after brain injury, and hemorrhagic volume were more than or equal to 2 mL. Totally 34 males and 6 females were enrolled, aged 16-72 years and 28 cases of them were younger than 40 years old. The prognosis of the patients was evaluated with Glasgow outcome scale (GOS) at 6 months after injury, and GOS scoring standard was 1-5 points (1 for dead; 2 for vegetative survival, long-term coma, manifestations of decorticate rigidity or decerebrate rigidity; 3 for severely disabled, should be look after by others; 4 for moderately disabled, be able in self-care; 5 for good recovery, adults can work and study).RESULTS: The enrolled cases accounted for 3.20% of the 1250 patients with closed brain injury admitted at the same period. ① The causes of injury included traffic accident in 36 cases, fall in 2 cases, and assault in 2 cases. ② At admission, the Glasgow coma scale (GCS) scores were as follow: 13-15 scores (mild) in 10 cases,9-12 scores (moderate)in 20 cases, and 3-8 scores (severe) in 10 cases. Hemiplegia presented in 37 cases,aphasia in 20 cases, conscious disturbance in 10 cases, unilateral mydriasis in 6 cases, and decerebrate rigidity in 2 cases. ③ TBGH was detected by CT within

    Full Text Available Access to deep-seated brain lesions with traditional fixed and rigid brain retractors can be difficult without causing significant trauma to the surrounding brain. Tubular retractors offer an advantage of low retracting pressure. We developed a new inexpensive and simple tubular retractor which requires very small cortisectomy. The new tubular retractor was made up of silicone with inner diameter of 15, 18 and 23 mm and outer diameter of 17, 20 and 25 mm, respectively. This tube (1 mm thick was cut in longitudinal direction. It was folded to make a small-diameter tube so that it could be introduced through a small cortisectomy. Margins of cortisectomy were gently and slowly retracted by Killian nasal speculum. Folded retractor, held by tissue forceps, was introduced inside the opened Killian nasal speculum. Tissue forceps and nasal speculum were removed leaving tubular retractor in place, which comes back to its normal tubular configuration after release. Surgery was performed using rigid Karl Storz 0° telescope (30 cm long and 4 mm in diameter or microscope. Near-total removals of intracerebral hematomas, 37 hypertensive and 3 traumatic, was done using this retractor without any complication.

    2011-01-01

    Full Text Available Gonadotropin-releasing hormone (GnRH agonists are derived from native GnRH by amino acid substitution which yields the agonist resistant to degradation and increases its half-life. The hypogonadotropic hypogonadal state produced by GnRH agonists has been often dubbed as "pseudomenopause" or "medical oophorectomy," which are both misnomers. GnRH analogues (GnRH-a work by temporarily "switching off" the ovaries. Ovaries can be "switched off" for the therapy and therapeutic trial of many conditions which include but are not limited to subfertility, endometriosis, adenomyosis, uterine leiomyomas, precocious puberty, premenstrual dysphoric disorder, chronic pelvic pain, or the prevention of menstrual bleeding in special clinical situations. Rapidly expanding vistas of usage of GnRH agonists encompass use in sex reassignment of male to female transsexuals, management of final height in cases of congenital adrenal hyperplasia, and preserving ovarian function in women undergoing cytotoxic chemotherapy. Hypogonadic side effects caused by the use of GnRH agonists can be tackled with use of "add-back" therapy. Goserelin, leuprolide, and nafarelin are commonly used in clinical practice. GnRH-a have provided us a powerful therapeutic approach to the treatment of numerous conditions in reproductive medicine. Recent synthesis of GnRH antagonists with a better tolerability profile may open new avenues for both research and clinical applications. All stakeholders who are partners in women′s healthcare need to join hands to spread awareness so that these drugs can be used to realize their full potential.

    Introduction Hematoma associated with epidural catheterization is rare, but the diagnosis might be suspected relatively frequently. We sought to estimate the incidence of suspected epidural hematoma after epidural catheterization, and to determine the associated cost of excluding or diagnosing an epidural hematoma through radiologic imaging. Methods We conducted an electronic retrospective chart review of 43,200 patient charts using 4 distinct search strategies and cost analysis, all from a single academic institution from 2001 through 2009. Charts were reviewed for use of radiological imaging studies to identify patients with suspected and confirmed epidural hematomas. Costs for imaging to exclude or confirm the diagnosis were related to the entire cohort. Results In our analysis, over a 9-year period that included 43,200 epidural catheterizations, 102 patients (1:430) underwent further imaging studies to exclude or confirm the presence of an epidural hematoma—revealing 6 confirmed cases and an overall incidence (per 10,000 epidural blocks) of epidural hematoma of 1.38 (95% CI 0, 0.002). Among our patients, 207 imaging studies, primarily lumbar spine MRI, were performed. Integrating Medicare cost expenditure data, the estimated additional cost over a 9-year period for imaging and hospital charges related to identifying epidural hematomas nets to approximately $232,000 or an additional $5.37 per epidural. Discussion About 1 in 430 epidural catheterization patients will be suspected to have an epidural hematoma. The cost of excluding the diagnosis, when suspected, is relatively low when allocated across all epidural catheterization patients. PMID:23924685

    Full Text Available Saul Perlmutter and the Brian Schmidt – Adam Riess teams reported that their Friedmann-model GR-based analysis of their supernovae magnitude-redshift data re- vealed a new phenomenon of “dark energy” which, it is claimed, forms 73% of the energy / matter density of the present-epoch universe, and which is linked to the further claim of an accelerating expansion of the universe. In 2011 Perlmutter, Schmidt and Riess received the Nobel Prize in Physics “for the discovery of the accelerating ex- pansion of the Universe through observations of distant supernovae”. Here it is shown that (i a generic model-independent analysis of this data reveals a uniformly expanding universe, (ii their analysis actually used Newtonian gravity, and finally (iii the data, as well as the CMB fluctuation data, does not require “dark energy” nor “dark matter”, but instead reveals the phenomenon of a dynamical space, which is absent from the Friedmann model.

    Background To expand the spectrum of ophthalmic manifestations in cat scratch disease. Methods Case report. Results A 7-year-old male was referred for evaluation of his left optic disc after failing vision screening test at school. His visual acuity was 20/20 OD and light perception OS. Fundus examination showed a left optic disc lesion associated with an exudative retinal detachment and vitreous seeding. Ultrasonography revealed a 7 × 7.5 × 3.8 mm lesion with a possible 6.3 mm of retrolaminar extension into the substance of the optic nerve. Brain MRI did not show evidence of optic nerve involvement but revealed a 6-mm nodule of the pineal gland suggestive of a pineoblastoma. Enucleation was performed and histopathology revealed a suppurative granulomatous inflammation suggestive of Bartonella infection. Upon further questioning, the patient had recent exposure to kittens with areas of cat scratches along both of his arms. He was subsequently referred to and treated with a 2-week course of trimethoprim-sulfamethoxazole and rifampin by the pediatric infectious disease specialist. Repeat brain MRI showed interval total resolution of enlarged pineal gland. Conclusion: Optic nerve granulomas are a rare presentation of cat scratch disease and could potentially masquerade as retinoblastoma. PMID:27843905

    2007-01-01

    The mammalian target of rapamycin (mTOR) has drawn much attention recently because of its essential role in cell growth control and its involvement in human tumorigenesis. Great endeavors have been made to elucidate the functions and regulation of mTOR in the past decade. The current prevailing view is that mTOR regulates many fundamental biological processes, such as cell growth and survival, by integrating both intracellular and extracellular signals, including growth factors, nutrients, energy levels, and cellular stress. The significance of mTOR has been highlighted most recently by the identification of mTOR-associated proteins. Amazingly, when bound to different proteins, mTOR forms distinctive complexes with very different physiological functions. These findings not only expand the roles that mTOR plays in cells but also further complicate the regulation network. Thus, it is now even more critical that we precisely understand the underlying molecular mechanisms in order to directly guide the development and usage of anti-cancer drugs targeting the mTOR signaling pathway. In this review, we will discuss different mTOR-associated proteins, the regulation of mTOR complexes, and the consequences of mTOR dysregulation under pathophysiological conditions.

    To describe when and how to perform endovascular embolization of aortic branch artery pseudoaneurysms associated with type A and type B intramural hematoma (IMH) involving the descending thoracic and abdominal aorta (DeBakey I and III) that increased significantly in size during follow-up. Sixty-one patients (39 men; mean {+-} standard deviation age 66.1 {+-} 11.2 years) with acute IMH undergoing at least two multidetector computed tomographic examinations during follow-up for 12 months or longer were enrolled. Overall, 48 patients (31 men, age 65.9 {+-} 11.5) had type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III). Among the 48 patients, 26 (54 %; 17 men, aged 64.3 {+-} 11.4 years) had 71 aortic branch artery pseudoaneurysms. Overall, during a mean follow-up of 22.1 {+-} 9.5 months (range 12-42 months), 31 (44 %) pseudoaneurysms disappeared; 22 (31 %) decreased in size; two (3 %) remained stable; and 16 (22 %) increased in size. Among the 16 pseudoaneurysms with increasing size, five of these (three intercostal arteries, one combined intercostobronchial/intercostal arteries, one renal artery), present in five symptomatic patients, had a significant increase in size (thickness >10 mm; width and length >20 mm). These five patients underwent endovascular embolization with coils and/or Amplatzer Vascular Plug. In all patients, complete thrombosis and exclusion of aortic pseudoaneurysm and relief of back pain were achieved. Aortic branch artery pseudoaneurysms associated with type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III) may be considered relatively benign lesions. However, a small number may grow in size or extend longitudinally with clinical symptoms during follow-up, and in these cases, endovascular embolization can be an effective and safe procedure.

    Acute subdural hematomas (aSDH) secondary to intracranial aneurysm rupture are rare. Most patients present with coma and their functional prognosis has been classically considered to be very poor. Previous studies mixed good-grade and poor-grade patients and reported variable outcomes. We reviewed our experience by focusing on patients in coma only and hypothesized that aSDH might worsen initial mortality but not long-term functional outcome. Between 2005 and 2013, 440 subarachnoid hemorrhage (SAH) patients were admitted to our center. Nineteen (4.3%) were found to have an associated aSDH and 13 (2.9%) of these presented with coma. Their prospectively collected clinical and outcome data were reviewed and compared with that of 104 SAH patients without aSDH who presented with coma during the same period. Median aSDH thickness was 10mm. Four patients presented with an associated aneurysmal cortical laceration and only one had good recovery. Overall, we observed good long-term outcomes in both SAH patients in coma with aSDH and those without aSDH (38.5% versus 26.4%). Associated aSDH does not appear to indicate a poorer long-term functional prognosis in SAH patients presenting with coma. Anisocoria and brain herniation are observed in patients with aSDH thicknesses that are smaller than those observed in trauma patients. Despite a high initial mortality, early surgery to remove the aSDH results in a good outcome in over 60% of survivors. Aneurysmal cortical laceration appears to be an independent entity which shows a poorer prognosis than other types of aneurysmal aSDH.

    Full Text Available Abstract Background The optimum protocol for expander volume adjustment with respect to the timing and application of radiotherapy remains controversial. Methods Eighteen New Zealand rabbits were divided into three groups. Metallic port integrated anatomic breast expanders of 250 cc were implanted on the back of each animal and controlled expansion was performed. Group I underwent radiotherapy with full expanders while in Group II, expanders were partially deflated immediately prior to radiotherapy. Control group did not receive radiotherapy. The changes in blood flow at different volume adjustments were investigated in Group II by laser Doppler flowmetry. Variations in the histopathologic properties of the irradiated tissues including the skin, capsule and the pocket floor, were compared in the biopsy specimens taken from different locations in each group. Results A significant increase in skin blood flow was detected in Group II with partial expander deflation. Overall, histopathologic exam revealed aggravated findings of chronic radiodermatitis (epidermal atrophy, dermal inflammation and fibrosis, neovascularisation and vascular changes as well as increased capsule thickness especially around the lower expander pole, in Group II. Conclusions Expander deflation immediately prior to radiotherapy, may augment the adverse effects, especially in the lower expander pole, possibly via enhanced radiosensitization due to a relative increase in the blood flow and tissue oxygenation.

    The vascular type of Ehlers-Danlos syndrome (vEDS) is an uncommon inherited disorder characterized by abnormalities in type III collagen, presenting itself as arterial dissection or rupture. We report a case of an isolated pulmonary hematoma mimicking a lung tumor in an 18-year-old man which turned out to be the initial finding of vEDS. Pneumothorax and hemothorax occurred repeatedly for 15 months following the surgical removal of the mass, and were treated by repeated left upper and lower lobectomy and thoracotomy. The diagnosis of vEDS was confirmed by pathologic and genetic studies.

    2011-01-01

    Full Text Available Vertex epidural hematomas (VEDHs are an uncommon situation and difficulties may be encountered in their diagnosis and management. This is more complicated when the surgical management has to be performed by general surgeons, not specialized in neurosurgery, in a remote location. It was in this context that we were brought to care in charge a 2-year-old boy who required a neurosurgical emergency rescue for a severe VEDH in Djibouti. Through the description of this case, we want to emphasize the value of developing a network of teleconsultation for the benefit of remote and isolated locations and learning basic techniques of emergency neurosurgery.

    Full Text Available Abstract Introduction Bilateral third nerve palsy secondary to a hemorrhagic stroke is exceptional. To the best of our knowledge, no similar case has been reported in the literature. Case presentation We describe the case of a 69-year-old Moroccan man who presented with isolated sudden bilateral third nerve palsy. Computed tomography (CT of the brain revealed a midbrain hematoma. The oculomotor function gradually and completely improved over eight months of follow-up. Conclusion Stroke should be included in the differential diagnosis of sudden isolated oculomotor paralysis even when it is bilateral because of the severity of the underlying disease and the importance of its therapeutic implications.

    A 53-year-old-man underwent US-guided percutaneous thermal ablation with a cooled-tip needle of three liver metastases from gastric cancer. Six days later, the patient was re-admitted for melena, scleral jaundice, and anemia. Abdominal US disclosed echogenic material in the gallbladder lumen (hemobilia) and a focal lesion with mixed echotexture in segment III (hepatic hematoma). On day 5 portal cavernomatosis was diagnosed at US and confirmed by color Doppler and a helical CT exam. The case described emphasizes that radio-frequency interstitial hyperthermia may cause not only traumatic injury of the liver parenchyma but also thermally mediated damage of vascular structures.

We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case.Case report: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications. Ureteroscopic laser lithotripsy was performed 5 months later by a urological trainee; it was difficult to negotiate the scope as vision became poor because of bleeding (as a result of the procedure. Postoperatively, hematuria persisted; temperature was 39°C. Cefuroxime was given intravenously followed by gentamicin for 5 days; hematuria subsided gradually; he was discharged home. Ten days later, this patient developed temperature, the urine culture grew Pseudomonas aeruginosa, and ciprofloxacin was given orally. Computed tomography (CT of the urinary tract, performed 4 weeks after ureteroscopy, revealed a 9×7 cm subcapsular collection on the left kidney compressing underlying parenchyma. Percutaneous drainage was not feasible because of severe curvature of spine. Isotope renogram revealed deterioration in left renal function from 30

    Gastric gastrointestinal stromal tumor (GIST) is one of the most common mesenchymal tumors of the stomach, which may be asymptomatic or cause symptoms such as pain, gastrointestinal bleeding, and obstruction. Hemoperitoneum due to spontaneous rupture of the tumor is an extremely rare complication. We described a case of a 52-year-old man with a large pedunculated GIST causing loculated hematoma within the gastrocolic ligament. The patient visited our hospital due to a 3 week history of epigastric pain. A computed tomography scan revealed a 10.3 x 7.5 x 9.4 cm sized mass that was growing exophytically from the greater curvature of the stomach and was surrounded by loculated hematoma within the gastrocolic ligament. Laparotomy revealed a large stalked gastric mass surrounded by loculated hematoma within the gastrocolic ligament and blood fluid in the peritoneal cavity. Pathologic examination confirmed a GIST, of the high risk group.

    This study aims to evaluate the ability of C-arm cone-beam CT to detect intracranial hematomas in canine models. Twenty one healthy canines were divided into seven groups and each group had three animals. Autologous blood and contrast agent (3 mL) were slowly injected into the left/right frontal lobes of each animal. Canines in the first group, the control group, were only injected with autologous blood without contrast agent. Each animal in all the 7 groups was scanned with C-arm cone-beam CT and multislice computed tomography (MSCT) after 5 minutes. The attenuation values and their standard deviations of the hematoma and uniformed brain tissues were measured to calculate the image noise, signal to noise ratio (SNR) and contrast to noise ratio (CNR). A scale with scores 1-3 was used to rate the quality of the reconstructed image of different hematoma as a subjective evaluation, and all the experimental data were processed with statistical treatment. The results revealed that when the density of hematoma was less than 65 HU, hematomata were not very clear on C-arm CT images, and when the density of hematoma was more than 65 HU, hematomata showed clearly on both C-arm CT and MSCT images and the scores of them were close. The coherence between the two physicians was very reliable. The same results were obtained with C-arm cone-beam CT and MSCT grades in measuring SD value, SNR, and CNR. The reasonable choice of density detection range of intracranial hematoma with C-arm cone-beam CT could be effectively applied to monitoring the intracranial hemorrhage during interventional diagnosis and treatment.

  20. [Chronicity, chronicization, systematization of delusions].

    1984-05-01

    Chronicity in psychopathology is indicative of a term, a decay. Chronicization only leads the way to this term. Here, chronicization is taken literally as an inscription in the time course of delusions. The mechanism of systematization seems to be a central mark in the approach to chronic delusions. It is not an alienation or an irreversible closing but an attempted accommodation with reality in the life of psychotic subjects, irrespective of the delusional structure. The role of therapy and drug treatment as a follow-up may in that case assume another meaning.

    Full Text Available : BACKGROUND: Chronic post herniorrhaphy groin pain is defined as pain lasting > 6 months after surgery, which is one of the most important complication occurring after inguinal hernia repair, occurs with greater frequency than previously thought. Chronic groin pain is one of the most significant complications following inguinal hernia repair, and majority of chronic pain has been attributed to ilioinguinal nerve entrapment. Various other factors are involved in development of chronic pain. MATERIAL AND METHODS: Patients undergoing elective inguinal hernioplasty in Victoria hospital from November2011 to May 2013 were included in the study. A total of 227 patients met the inclusion criteria and were available for follow up at end of six months. A detailed preoperative, intraoperative and post-operative details of cases were recorded according to proforma. The postoperative pain and pain at two, seven days and at end of six months were recorded on a VAS scale. RESULTS: Chronic pain at six month follow up was present in 89 patients constituting 39.4% of all patients undergoing hernia repair. It was seen that 26.9% without preoperative pain developed chronic pain whereas 76.7 % of patients with preoperative pain developed chronic pain. Patients with significant preoperative pain had higher chances of developing chronic pain (p<.0001. Preemptive analgesia failed to show statistical significance in development of chronic pain (p=0.079. Nerve injury were present in 22 of cases it was found that nerve injury significantly affected development of chronic pain (p=0.001.Post-operative infiltration of local anesthesia was practiced in 16.3 % of cases and it was found that local infiltration at incision site significantly reduced incidence of chronic pain (p=0.001.Postoperative complications in the form of hematoma, seroma or infection was present in 8.5 % of cases. It was found that post-operative complication not only increased early post-operative pain

    Full Text Available Abstract Introduction Symptomatic subdural hematoma development is a constant concern for patients who have undergone cerebrospinal fluid shunting procedures to relieve symptoms related to normal-pressure hydrocephalus. Acute subdural hematomas are of particular concern in these patients as even minor head trauma may result in subdural hematoma formation. The presence of a ventricular shunt facilitates further expansion of the subdural hematoma and often necessitates surgical treatment, including subdural hematoma evacuation and shunt ligation. Case presentation We present the case of a 63-year-old North American Caucasian man with normal-pressure hydrocephalus with an adjustable valve ventriculoperitoneal shunt who developed an acute subdural hematoma after sustaining head trauma. Conservative treatment was favored over operative evacuation because our patient was neurologically intact, but simple observation was considered to be too high risk in the setting of a low-pressure ventriculoperitoneal shunt. Thus, the valve setting on the ventriculoperitoneal shunt was increased to its maximum pressure setting in order to reduce flow through the shunt and to mildly increase intracranial pressure in an attempt to tamponade any active bleeding and limit hematoma expansion. A repeat computed tomography scan of the head six days after the valve adjustment revealed complete resolution of the acute subdural hematoma. At this time, the valve pressure was reduced to its original setting to treat symptoms of normal-pressure hydrocephalus. Conclusions Programmable shunt valves afford the option for non-operative management of acute subdural hematoma in patients with ventricular shunts for normal-pressure hydrocephalus. As illustrated in this case report, increasing the shunt valve pressure may result in rapid resolution of the acute subdural hematoma in some patients.

    Hypernatremia has been causally linked with subdural hematoma (SDH), but more recently this has been called into question. Conversely, there is a well-established link between SDH and injury. We wish to examine the evidence base that hypernatremia in infants and young children causes SDH.We present 2 cases of children with severe hypernatremia whose intracranial contents were assessed by imaging in the first case and postmortem examination in the second. Neither demonstrated SDH. The first case was important as the hypernatremia was iatrogenic occurring in a controlled hospital environment.We also searched the literature from 1950 to 2007, collecting data on all reported cases of hypernatremia in children younger than 7 years whose intracranial contents were examined by imaging, surgery, and/or postmortem examination. Of 124 cases reported in 31 articles, 112 cases developed hypernatremia in the community, and 12 in the hospital. Subdural hematoma was demonstrated in 7 cases, all of which had developed hypernatremia in the community under circumstances that would make it difficult to exclude nonaccidental injury. None of the 12 cases that developed hypernatremia in a controlled hospital environment had SDH.The evidence base supporting the hypothesis that hypernatremia causes SDH is poor, depending on isolated reports with uncertain histories.

    Introduction. In acute stroke by occlusion of the proximal medial cerebral artery (MCA) or the distal internal carotid artery, intravenous thrombolysis is an established treatment. Another option is mechanical recanalization. It remains unclear if the combination of both methods poses an additional bleeding risk. The aim of this retrospective analysis is to determine the proportion of hemorrhagic infarctions and parenchymal hematomas. Methods. Inclusion criteria were an occlusion of the carotid T or proximal MCA treated with full dose thrombolysis and mechanical recanalization. 31 patients were selected. Devices used were Trevo, Penumbra Aspiration system, Penumbra 3D Retriever, and Revive. The initial control by computed tomography was carried out with a mean delay to intervention of 10.9 hours (SD: 8.5 hours). Results. A slight hemorrhagic infarction (HI1) was observed in 2/31 patients, and a more severe HI2 occurred in two cases. A smaller parenchymal hematoma (PH1) was not seen and a space-occupying PH2 was seen in 2/31 cases. There was no significant difference in the probability of intracranial bleeding after successful (thrombolysis in cerebral infarctions 2b and 3) or unsuccessful recanalization. Conclusion. The proportion of intracranial bleeding using mechanical recanalization following intravenous thrombolysis appears comparable with reports using thrombolysis alone. PMID:26640710

    Full Text Available Subdural hematoma (SDH is a common condition in infancy and young children with a poor prognostic. The more studies related SDH with nonaccidental injury. With the aim to identify the characteristics of SDH in infants below 1 year, a retrospective study of infants below 1 year diagnosed as subdural hematoma who were admitted to PICU Hasan Sadikin General Hospital from Januari 2000 to Desember 2003 has been conducted. Infants less than 1 month and SDH developed after neurosurgery intervention were excluded. Fourteen infants met the inclusion criteria's, consisted of 5 (36% girls and 9 (64% boys, most of them were on 1 month of age (57%. Anemia was found on all cases, thrombocyte normal except in 1 case thrombocytopenia (53,000/mm3. PT prolonged in 9 (100% cases and PTT in 5 (56% from 9 cases. Bilirubin total/direct elevated in 4 (80% from 5 cases, SGOT/SGPT elevated in 5 (83% from 6 cases. From 11 cases, 9 (82% cases were IgG anti-CMV positive and 6 (55% cases were IgM anti CMV positive. Conclusions, SDH can be caused by various etiologies, thus a comprehensive examinations to exclude child abuse are needed. The role of CMV infection should be considered as one of SDH etiology.

    Acute subdural hematoma (ASDH) can cause massive ischemic cerebral blood flow (CBF) underneath the hematoma, but early surgical evacuation of the mass reduces mortality. The aim of this study was to evaluate whether arundic acid improves the secondary ischemic damage induced by ASDH. Our results confirmed that arundic acid decreases the expression of S100 protein produced by activated astrocytes around ischemic lesions due to cytotoxic edema after ASDH as well as reducing infarction volumes and numbers of apoptotic cells around the ischemic lesions. In this study, we also evaluate the relationship of brain edema and the expression of Aquaporin 4 (AQP4) in an ASDH model. The expression of AQP4 was decreased in the acute phase after ASDH. Cytotoxic edema, assumed to be the main cause of ASDH, could also cause ischemic lesions around the edema area. Arundic acid decreased the infarction volume and number of apoptotic cells via suppression of S100 protein expression in ischemic lesions without changing the expression of AQP4.

Slit lamp examination revealed both eyes having congenital cataract. Right eye lens aspiration was performed but was uneventful, and he prepared for left eye surgery after 7 days. Immediately after giving a peribulbar block, a complete akinesia, tight eyelids, and stony hard eyeball was noted. An abaxial proptosis of 7 mm was noted. Lateral canthotomy and inferior cantholysis were done and proptosis reduced to 5 mm. Bleeding time–clotting time was normal. Proptosis worsened to 8 mm the next day. Contrast-enhanced computed tomography scan showed inferolateral subperiosteal hematoma, but drainage could not be performed due to prolonged prothrombin time and activated prothrombin time. Fresh frozen plasma was transfused. Tarsorrhaphy was performed for exposure keratopathy after his coagulation profile became normal. Hematology evaluation after 2 weeks detected factor V deficiency, and was diagnosed as Owren's disease or parahemophilia.

    A 44-year-old man who drove a motorcycle experienced a collision with the side of another motorcycle. Because he had sustained a high-energy injury to the spinal cord, he was transferred to our hospital. His circulation was unstable, and received tracheal intubation in addition to thoracostomy for the hemothorax. Whole-body computed tomography (CT) revealed multiple fractures, right hemopneumothorax with pulmonary contusion, and minor liver injury. After infusing 5000 mL of lactated Ringer's solution and 10 units of blood, his circulation remained unstable. On a repeat CT examination, the left atrium was found to be compressed by a posterior mediastinal hematoma induced by the fracture of the thoracic spine, and a diagnosis of shock induced by multiple factors, including hemorrhagic, neurogenic, and obstructive mechanisms, was made. After obtaining stable circulation and respirations, internal fixation of the extremities and extubation were performed on the 12th hospital day. Chest CT performed on the 27th day showed the disappearance of compression of the left atrium by the hematoma.

This study compared multiple surgical and prognostic parameters of SWCT versus ordinary large-window craniotomy (LWCT, which aimed at providing evidences for surgical decision. Compared with LWCT (N = 51, SWCT (N = 44 displayed shortened average operation time (P = 0.000, reduced intraoperative blood loss (P = 0.000 and lessened intraoperative blood transfusion (P = 0.031. Moreover, there was no differences of postoperative residual hematoma (P = 0.141, postoperative palinesthesia time (P = 0.201, the ratio of postoperative secondary ischemia (P = 0.865 or cerebral edema (P = 0.879, and 6-month Glasgow Outcome Scale (GOS score (P = 0.603 between the two surgical approaches.  Results suggested that, for patients with acute epidural hematoma and concurrent early-phase cerebral herniation, SWCT could effectively evacuate hematoma and relief brain herniation without significant differences of effect and prognosis from LWCT. In addition, SWCT has several advantages such as significantly reduced operation time, intraoperative blood loss and blood transfusion. doi: 10.3969/j.issn.1672-6731.2014.05.013

    Medical literature about chronic hepatitis is reviewed. This unresolving disease caused by viruses, drugs or unknown factors may progress to in cirrhosis and hepatocarcinoma. A classification based on liver biopsy histology into chronic persistent and chronic active types has been largely abandoned and emphasis is placed on recognizing the etiology of the various types. One is associated with continuing hepatitis B virus infection; another is related to chronic hepatitis C virus infection and the third is termed autoinmune, because of the association with positive serum autoantibodies. A fourth type with similar clinical functional and morphologic features is found with some drug reactions. Long term corticoesteroid therapy is usually successful in autoinmune type. Associations between antibodies to liver-kidney microsomes and the hepatitis C virus can cause diagnostic difficulties. Antiviral treatment of chronic hepatitis B and C with interpheron alfa is employed, controlling symptoms and abnormal biochemistry and the progression to cirrhosis and liver cancer in 30 to 40% patients. Alternative therapies or combinations with interpheron are being evaluated waiting for final results.

Todos os pacientes foram atendidos de acordo com o mesmo protocolo. Houve predominância do sexo masculino (79%, com idade variando entre 14 e 70 anos, sendo os atropelamentos (34% e os acidentes automobilísticos (20% as causas mais comuns. A maioria dos pacientes (85,7% foi admitida muito grave, com 8 pontos ou menos na Escala de Coma Glasgow (ECG, o que influenciou diretamente na mortalidade. A tomografia computadorizada de crânio foi o exame diagnóstico de escolha que mostrou serem as contusões e o inchaço cerebral ("swelling" as lesões intracranianas associadas mais freqüentes. A cirurgia foi realizada em 45,1% dos pacientes, e, em sua maioria, através de craniotomia fronto-têmporo-parietal ampla, com drenagem do hematoma, seguida de plástica da dura-mater. Em 54,9% as condições clínicas não permitiram a realização da cirurgia; neste grupo, cerca de 69,6% estavam em coma profundo à admissão, com 3 pontos na ECG. A letalidade cirúrgica foi de 61,2% e esteve diretamente relacionada à condição clínica inicial e à idade do paciente. A letalidade, incluindo todos os pacientes cirúrgicos e não cirúrgicos com HSDA, mesmo aqueles admitidos já com sinais de falência de tronco cerebral, foi de 79,5%.

    OBJECT: In this paper the authors investigate whether shunt-treated patients with normal-pressure hydrocephalus receiving aspirin therapy are at increased risk of developing subdural hematoma (SDH). METHODS: Records from 80 consecutive patients who had undergone implantation of a cerebrospinal...... fluid shunt for the treatment of normal-pressure hydrocephalus were retrospectively reviewed. RESULTS: Eleven cases of symptomatic SDH occurred, all among patients receiving aspirin or clopidogrel. The 5-year survival estimate was 0.3 (p ...% CI 3.1-53). CONCLUSIONS: Patients on an aspirin therapy regimen have a markedly increased risk of SDH after a shunt has been implanted for the treatment of normal-pressure hydrocephalus. Users of clopidogrel may have an even greater risk....

  7. Interaction of age and mechanical stability on bone defect healing: an early transcriptional analysis of fracture hematoma in rat.

    Directory of Open Access Journals (Sweden)

    Andrea Ode

    Full Text Available Among other stressors, age and mechanical constraints significantly influence regeneration cascades in bone healing. Here, our aim was to identify genes and, through their functional annotation, related biological processes that are influenced by an interaction between the effects of mechanical fixation stability and age. Therefore, at day three post-osteotomy, chip-based whole-genome gene expression analyses of fracture hematoma tissue were performed for four groups of Sprague-Dawley rats with a 1.5-mm osteotomy gap in the femora with varying age (12 vs. 52 weeks - biologically challenging and external fixator stiffness (mechanically challenging. From 31099 analysed genes, 1103 genes were differentially expressed between the six possible combinations of the four groups and from those 144 genes were identified as statistically significantly influenced by the interaction between age and fixation stability. Functional annotation of these differentially expressed genes revealed an association with extracellular space, cell migration or vasculature development. The chip-based whole-genome gene expression data was validated by q-RT-PCR at days three and seven post-osteotomy for MMP-9 and MMP-13, members of the mechanosensitive matrix metalloproteinase family and key players in cell migration and angiogenesis. Furthermore, we observed an interaction of age and mechanical stimuli in vitro on cell migration of mesenchymal stromal cells. These cells are a subpopulation of the fracture hematoma and are known to be key players in bone regeneration. In summary, these data correspond to and might explain our previously described biomechanical healing outcome after six weeks in response to fixation stiffness variation. In conclusion, our data highlight the importance of analysing the influence of risk factors of fracture healing (e.g. advanced age, suboptimal fixator stability in combination rather than alone.

  8. Electrical Properties of Expanded Graphite Intercalation Compounds

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The intercalation compounds of CuCl2 were synthesized with expanded graphite, whose magnitude of the electrical conductivity is about 103S.cm-1. Their electrical conductivity is 3~6 times as high as that of the expanded graphite, and about 10 times as high as that of GIC made of the non-expanded graphite. The microanalysis results of chemical compounds by X-ray energy spectrum scanning of TEM testified that the atomic ratio of chloride and cupric is nonstoichoimetric. The multivalence and exchange of electrovalence of the cupric ion was confirmed by the XPS-ESCA. Vacancy of chlorine anion increases the concentration of charge carrier.The special stage structure, made of graphite and chloride, produces a weak chemical bond belt and provides a carrier space in the direction of GIC layer. These factors develop the electrical properties.

  9. Analog model for an expanding universe

    Weinfurtner, S E C

    2004-01-01

    Over the last few years numerous papers concerning analog models for gravity have been published. It was shown that the dynamical equation of several systems (e.g. Bose-Einstein condensates with a sink or a vortex) have the same wave equation as light in a curved-space (e.g. black holes). In the last few months several papers were released which deal with simulations of the universe. In this article the de-Sitter universe will be compared with a freely expanding three-dimensional spherical Bose-Einstein condensate. Initially the condensate is in a harmonic trap, which suddenly will be switched off. At the same time a small perturbation will be injected in the center of the condensate cloud. The motion of the perturbation in the expanding condensate will be discussed, and after some transformations the similarity to an expanding universe will be shown.

    The Schwarzchild solution insertion in an expanding universe, the so-called "Swiss cheese model," is shown to possess an extrinsic curvature miss-match. One consequence is that some trajectories are discontinuous functions of their initial conditions. An alternate metric is proposed which goes smoothly between the Schwarzchild exterior solution and the Friedmann-Lemaitre, expanding universe metric. It is further shown that the effects of the expansion on planetary motions in the solar system are too small to be currently observed for this alternate metric.

    Bernui, Armando

    The dynamics of a coupled model (harmonic oscillator-relativistic scalar field) in Conformal Robertson-Walker (k = +1) spacetimes is investigated. The exact radiation-reaction equation of the source-including the retarded radiation terms due to the closed space geometry - is obtained and analyzed. A suitable family of Lyapunov functions is constructed to show that, if the spacetime expands monotonely, then the source's energy damps. A numerical simulation of this equation for expanding Universes, with and without Future Event Horizon, is performed.

    Rotary Wankel engines offer several advantages compared with turbines and other positive-displacement machines as the expansion devices in low-power-output Rankine-cycle systems. So a Wankel expander was selected as the most appropriate device for a steam Rankine-engine, operating principally as a mini combined heat-and-power unit, providing a mechanical output of 5-20 kW. A computer-aided-design technique for selecting the optimal geometry and location of the ports of the expander is described: the computer programs are available from the authors. Lubrication and possible material combinations are also discussed. (author).

    Full Text Available OBJECTIVE: To assess the therapeutic outcome after endovascular repair of iliac arterial lesions (IALs using a self-expandable Nitinol stent graft system. METHODS: Between July 2006 and March 2013, 16 patients (13 males, mean age: 68 years with a self-expandable Nitinol stent graft. A total of 19 lesions were treated: nine true aneurysms, two anastomotic aneurysms, two dissections, one arteriovenous fistula, two type 1B endoleaks after endovascular aneurysm repair, one pseudoaneurysm, and two perforations after angioplasty. Pre-, intra-, and postinterventional imaging studies and the medical records were analyzed for technical and clinical success and postinterventional complications. RESULTS: The primary technical and clinical success rate was 81.3% (13/16 patients and 75.0% (12/16, respectively. Two patients had technical failure due to persistent type 1A endoleak and another patient due to acute stent graft thrombosis. One patient showed severe stent graft kinking on the first postinterventional day. In two patients, a second intervention was performed. The secondary technical and clinical success rate was 87.5% (14/16 and 93.8% (15/16. The minor complication rate was 6.3% (patient with painful hematoma at the access site. The major complication rate was 6.3% (patient with ipsilateral deep vein thrombosis. During median follow-up of 22.4 months, an infection of the aneurysm sac in one patient and a stent graft thrombosis in another patient were observed. CONCLUSION: Endovascular repair of various IALs with a self-expandable Nitinol stent graft is safe and effective.

  16. Chronic gastritis.

    2015-06-01

    Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. However, chronic gastritis is still one of the most common serious pandemic infections with such severe killing sequelae as peptic ulcer or gastric cancer. Globally, on average, even more than half of people may have a chronic gastritis at present. Helicobacter pylori infection in childhood is the main cause of chronic gastritis, which microbial origin is the key for the understanding of the bizarre epidemiology and course of the disease. A life-long and aggressive inflammation in gastritis results in destruction (atrophic gastritis) of stomach mucosa with time (years and decades). The progressive worsening of atrophic gastritis results subsequently in dysfunctions of stomach mucosa. Atrophic gastritis will finally end up in a permanently acid-free stomach in the most extreme cases. Severe atrophic gastritis and acid-free stomach are the highest independent risk conditions for gastric cancer known so far. In addition to the risks of malignancy and peptic ulcer, acid-free stomach and severe forms of atrophic gastritis may associate with failures in absorption of essential vitamins, like vitamin B12, micronutrients (like iron, calcium, magnesium and zinc), diet and medicines.
