    Arachnoid granulations (AG) are composed of dense, collagenous connective tissue that includes clusters of arachnoid cells. They tend to invaginate into the dural sinuses, through which cerebrospinal fluid enters the venous system. AG are most commonly seen at the junction between the middle and lateral thirds of the transverse sinuses near the entry sites of the superficial veins. Presently described is the case of a 21-year-old female who presented at the clinic with recurrent headaches. Magnetic resonance (MR) imaging revealed a 3.5-cm lesion, which extended from confluens sinuum through the superior sagittal sinus. The lesion had created a scallop-shaped area of erosion in the neighboring occipital bone. To exclude sinus thrombosis, MR venography was performed, which displayed a maintained venous flow around the lesion. Headaches were treated symptomatically with medical therapy. Giant AG can be misdiagnosed as dural sinus thrombosis. MR imaging combined with MR venography is the most useful diagnostic tool to differentiate giant AG from dural sinus thrombosis.

    Full Text Available The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

    We present a case of angiographically confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an iso signal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

    Four adult patients were diagnosed as having dural sinus thrombosis (DST) by means of magnetic resonance (MR). In the three cases of acute thrombosis, MR disclosed diffuse or segmental hyperintensity in the sinuses involved, which persisted regardless of the sequence and orientation of the plane selected. MR angiography (MRA) provided diagnostic information that proved useful in the chronic case, as well as in the two cases in which follow-up was carried out to determine the degree to which permeability was restored to the sinuses involved. MR diagnosis of DST can produce false positives and negatives, the causes of which should be known, as well as the ways to avoid them, in order to prevent diagnostic errors. MR, when applied and interpreted correctly, can be considered the first, and in many cases the only, choice as a diagnostic method in DST. (Author)

    Full Text Available The dural sinus thrombosis is an uncommon complication of a commonly done procedure of central venous catheterisation. We present a case of massive hemorrhagic venous infarct with gross cerebral edema due to dural sinus thrombosis along with right internal jugular vein thrombus. A 21-year-old male patient presented to the emergency department with fever and swelling of the right neck four days following discharge after his prior hospitalization two weeks ago for acute renal failure due to severe gastroenteritis, when he underwent hemodialysis through right internal jugular access. On presentation, he was conscious, with swelling on right side of the neck, which was diagnosed as right internal jugular vein occlusion. However, he rapidly dete-riorated and developed signs of raised intracranial pressure despite being on treatment with heparin. He was diagnosed as having massive hemorrhagic cerebral venous infarct with gross cerebral edema complicated with shift of the ventricles to the left due to dural sinus thrombosis. Despite emergency decompressive craniotomy, he succumbed in the next two days due to coning. Asymptomatic catheter-related thrombosis is frequent in the intensive care units, but major complications like retrograde extension into dural sinus causing thrombosis is rare. A high index of suspicion is required to diagnose this major catastrophe for an early and meaningful intervention.

    Dural venous sinus ectasia with thrombosis (DVSET) in the fetus is a rare condition that can be diagnosed prenatally with the use of fetal MR imaging, yet with limited indication of long-term clinical significance. To describe and evaluate the diagnostic value of fetal MR imaging in the prenatal diagnosis of dural venous sinus ectasia with thrombosis and its clinical significance. We report a series of nine fetuses with dural venous sinus ectasia with thrombosis. The mothers, located in four feto-maternal centres, were referred for fetal MR imaging due to space occupying lesions identified on second-trimester antenatal ultrasound. In all but one case the dural venous sinus ectasia with thrombosis was in the vicinity of the venous confluence (VC) with various extension in the posterior dural sinuses. Antenatal follow-up imaging was performed in seven cases and showed progression in one, stable appearances in one and regression in five cases. Three pregnancies were terminated. In the remaining six cases there was no reported neurological deficit at up to 44 months of clinical follow-up. This is among the largest series of postnatal clinical follow-up in cases of prenatal diagnosis of dural venous sinus ectasia with thrombosis in the literature. Clinical follow-up suggests a good prognosis when antenatal follow-up shows partial or complete thrombus resolution. (orig.)

    Full Text Available Transverse (lateral sinus thrombosis is a well-known complication of acute otitis media and mastoiditis in the pediatric and adult population. Thrombosis involving the transverse sinus can ultimately cause elevation of intracranial pressure (ICP as a result of decreased cerebrospinal fluid absorption. If treatment to lower ICP is not undertaken, it can lead to ophthalmological complications including irreversible vision loss. The following case report describes an 11-year-old girl who was diagnosed with AOM by her pediatrician and subsequently presented to the emergency department complaining of nausea, vomiting, headache, and diplopia.

    Thrombosis of fetal intracranial dural sinuses is a rare entity. A specific type of midline dural sinus thrombosis (DST) at the torcular Herophili with extension into the superior sagittal sinus (SSS) was initially seen on fetal US and was referred to fetal MRI for definite diagnosis and better delineation. Retrospective comparison to medical literature of three cases, diagnosed at our institution, of midline fetal DST with MR imaging findings and clinical outcomes. We reviewed MRI findings on T2-weighted images of our three cases of fetal midline DST and clinical outcomes of these fetuses and compared our findings to medical literature. The MR imaging and clinical findings of our cases extend over 6 years. They consist of three pregnant women, 31-39 years of age each with a single fetus, with fetal MR imaging performed at different gestational ages (GA). Case 1 the MR imaging was performed at 21 5/7 weeks' GA, case 2 at 24 and 33 4/7 weeks' GA, and case 3 at 22 and 25 weeks' GA. Postnatal MRI was performed in case 2 at 6 months of life and case 3 at 1 day of life. Clinical follow-up occurred during the last 6 years. In all of our cases, T2-W MR imaging demonstrated ballooned midline torcular Herophili with iso- to hypointense mass with or without focal eccentric area of greater hypointensity occupying the torcular Herophili with extension into the SSS. Case 3 had associated leptomeningeal dural vascular malformation overlying the left cerebral hemisphere with development of migrational disorder in the left cerebral hemisphere. Clinical outcome consisted of fetal demise in case 1, normal postnatal outcome in case 2 and severe brain damage with poor postnatal outcome in case 3. Our findings of large iso-hypointense thrombus with or without a focal eccentric area more hypointense to thrombus in a dilated torcular Herophili with extension into the SSS on T2-W images corresponds to the majority of cases of this rare type of DST in the medical literature

    Full Text Available O pseudotumor cerebral é uma síndrome neurológica relativamente comum na adolescência. Na maioria dos casos, a etiologia é idiopática, mas pode haver complicações graves, como cegueira, relacionadas com a hipertensão intracraniana. O objetivo deste artigo é enfatizar o diagnóstico diferencial do pseudotumor cerebral, com atenção especial às etiologias tratáveis. Relatamos o caso de um adolescente de 12 anos que se apresentou com diplopia e cefaléia 9 dias após otite média e mastoidite à direita. A tomografia computadorizada do crânio foi normal, mas a ressonância magnética do encéfalo detectou trombose dos seios transverso e sigmóideo ipsilaterais, a qual respondeu à anticoagulação precoce. A conclusão é que a ressonância magnética do encéfalo é essencial nos pacientes com diagnóstico clínico de pseudotumor cerebral para exclusão de causas tratáveis, como a trombose venosa dural.Pseudotumor cerebri is a relatively common neurologic syndrome in adolescence. In most cases, etiology is idiopathic, but it may have serious complications, such as blindness, that are related to increased intracranial pressure. The aim of this article is to emphasize the differential diagnosis of pseudotumor cerebri, with special attention to treatable etiologies. We report a case of an 12 year-old adolescent who presented with diplopia and headache 9 days after right-sided otitis media and mastoiditis. Head computerized tomography was normal, but brain magnetic resonance imaging demonstrated thrombosis of ipsilateral transverse and sigmoid sinuses, which responded promptly to early anticoagulation. The conclusion is that magnetic resonance imaging is essential for patients with a clinical diagnosis of pseudotumor cerebri in order to exclude treatable causes, such as dural sinus thrombosis.

    We aimed to define the possible risk factors for acute and remote seizures in patients with cerebral vein and sinus thrombosis (CVST). Ninety-four patients were recruited prospectively at Al-Zahra Hospital, Isfahan, Iran, between April 2007 and April 2012. To identify seizure predictors, we compared demographic, clinical and imaging factors between patients with or without acute and remote seizures. Of the 94 patients, 32 (34%) experienced at least one seizure after CVST development. Bivariate analysis showed a significant association of remote seizure with loss of consciousness at presentation (P=0.05, OR: 5.11, 95%CI: 1.07-24.30), supratentorial lesions (P=0.02, OR: 9.04, 95%CI: 1.04-78.55), lesions in the occipital lobe (P=0.00, OR: 12.75, 95%CI: 2.28-71.16), lesions in the temporal and parietal lobes, thrombophilia (P=0.03, OR: 5.87, 95%CI: 1.21-28.39), seizure in the acute phase (P=0.00, OR: 13.14, 95%CI: 2.54-201.2) and sigmoid sinus thrombosis (P=0.00, OR: 12.5, 95%CI: 2.23-69.79). Seizures in the acute phase were also more common in patients with paresis (P=0.00, OR: 4.88, 95%CI: 1.91-12.46), hemorrhagic lesions indicated by imaging (P=0.02, OR: 2.77, 95%CI: 1.08-7.10), supratentorial lesions, lesions in the frontal (P=0.01, OR: 3.81, 95%CI: 1.28-11.31) and parietal lobes (P=0.00, OR: 5.16, 95%CI: 2-13.29), thrombophilia and history of miscarriage (P=0.03, OR: 2.91, 95%CI: 1.07-7.91). No factor predicted acute or remote seizure in a multiple logistic regression analysis. Our results demonstrate that seizure development in the acute phase is the most significant factor for development of remote seizure. Parenchymal lesions in the supratentorial area were also found to be associated with both acute and remote seizures. However, no factor was predictive of acute or remote seizures in a multivariate analysis. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Full Text Available A 55 year old male patient was operated on for a massive and vascular acoustic neurinoma in a sitting position. The tumor was completely excised. Post-operatively, the patient developed irritability and clinical features suggestive of contralateral cavernous sinus thrombosis. CT scan showed air within the dural walls of the cavernous sinus on the side of surgery. However, there was no radiological evidence of cavernous sinus thrombosis on the contralateral side. Cavernous sinus thrombosis as a post-surgery complication has not been reported. Air within the dural confines of the cavernous sinus has also not been observed or radiologically recorded in the literature.

    Cerebral sinus venous thrombosis (CSVT) is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT) and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment. PMID:24347950

    Although hormonal influences, inflammation, trauma, sinus thrombosis, venous hypertension, and congenital origin have been proposed as sources of dural arteriovenous fistulas (DAVFs) in cavernous and sigmoid sinuses, the etiology of these lesions remains controversial. We present a case with a cavernous sinus DAVF developed from viral meningitis which has not been previously described. A 24-year-old male was admitted to our institute because of periorbital pain, decreased vision, pulsatile tinnitus, chemosis, and exophthalmos on the right side after he had suffered viral meningitis four months before. Cerebral angiography demonstrated a cavernous sinus DAVF, which was successfully obliterated with several platinum coils using a transvenous approach. The viral meningitis most likely caused the inflammation, that may be responsible for the occurrence of the cavernous sinus DAVF. Prompt treatment for inflammation may help to prevent the development of DAVFs.

    Cerebral venous thrombosis (CVT) accounts for 0.5-1 % of all strokes. Although dural puncture is proposed as one of the rare risk factors, this association has only been mentioned in anecdotal reports. Headache, i.e., usually the first and the most frequent clinical symptom on admission, is often attributed to the dural puncture itself. We investigated the frequency of CVT following a recent dural puncture in our stroke database, together with the other risk factors. The computerized medical records of patients (n = 10,740) registered in our tertiary-care neurology clinic stroke database were reviewed retrospectively. Patients diagnosed with CVT were reanalyzed. Patients who had a dural puncture in the preceding 7 days were included in the study. A total of 46 patients were diagnosed with CVT. Nine patients (19.6 %) had a recent dural puncture before the onset of the symptoms. Patients were younger than 45 years and had at least one more predisposing condition for thromboembolism other than the dural puncture. All patients have received either spinal anesthesia or intrathecal chemotherapy. Dural puncture seems to trigger CVT particularly in patients with predisposing disorders. Although reported as an extremely rare complication, our data indicate a much higher association. This case series emphasize the importance of reevaluation of patients with persistent/progressive headache following dural puncture. The effect of change in the biochemical composition of CSF due to intrathecal drug administration in pathogenesis is not known. Larger controlled trials are warranted to clarify the causal relationship between lumbar puncture and/or intrathecal drug administration and CVT.

    BACKGROUND: The pathological mechanism of secondary brain lesion following an embolism remains unclear. The establishment of an animal model that imitates the clinical pathophysiological processes is crucial to better study this disease during a certain time window.OBJECTIVE: To establish a new animal model of dural venous sinus embolism that is simple, has a high success rate, and emulates the pathophysiological course of clinical disease.DESIGN, TIME AND SETTING: A randomized block design trial was performed at the Department of Anatomy, Ningxia Medical College between March and December 2007.MATERIALS: Fifty-eight healthy, adult, Sprague Dawley rats were used in the present study. Plastic emboli, with a total length of 0.4cm, were self-made. Each plastic embolus had a conical anterior segment; the largest diameter being 0.12cm. The posterior segment became gradually thin and flat, with a width of 0.2cm and length of 0.1cm.METHODS: The fifty-eight rats were randomly divided into three groups: control (n=6), embolism (n=26), and sham-embolism (n=26) groups. In the embolism group, a solid embolus was slowly inserted and fixed into the posterior part of the superior sagittal sinus against the flow of blood. The posterior segment was detained outside the superior sagittal sinus for fixing. In the sham-embolism group, rats were subjected only to sinus sagittalis superior exposure. In the control group, rats received no treatments. In both the embolism and the sham-embolism groups, the rat brains were resected at 6 hours, 1,3, and 5 days post-surgery.MAIN OUTCOME MEASURES: (1) Brain surface appearance in the embolism and sham-embolism groups. (2) Thrombosis in the embolism group. (3) Cerebrospinal fluid content in the above-mentioned two groups.RESULTS: In the embolism group, the model success rate was 92%(24/26). There was visible thrombosis in the superior sagittal sinus. Cerebral edema was noticeable under a microscope. These changes were visible at 6 hours after

    To determine technical success and acute complication rates after endovascular coil packing of the cavernous sinus. Nineteen patients presented with either direct (13) or dural (6) arteriovenous fistula (AVF) and were treated by means of coil embolization of the cavernous sinus. The aim of treatment was complete obliteration of the fistula. In a retrospective study, the degree of obliteration, regression of symptoms as well as complication rates were evaluated. Initial complete obliteration was achieved in 12 patients, subtotal occlusion of the sinus in 6 and incomplete packing with major residual fistula in 1 of the patients. Retreatment was successfully performed in two patients with early recurrence of AVF. Follow-up showed complete occlusion rates in 16 and subtotal obliteration in 3 patients. Chemosis and exophthalmus regressed rapidly in all affected patients. Persistence of cranial nerve deficits was observed in 11 cases. Postinterventional thrombosis of the ophthalmic vein was the only major acute complication (n = 2). Coil embolization of the cavernous sinus in cases with AVF is a complex procedure that is technically feasible and safe in the majority of cases. Adequate anticoagulation is recommended to avoid thrombembolic complications. Long-term outcome has to be determined by further studies. (orig.)

    OBJECTIVE The aim of this study is to describe the clinical characteristics of patients with skull fracture adjacent to a dural venous sinus (DVS) and evaluate the role of CT venography (CTV) in the diagnosis of the effect of this fracture on the involved DVS. METHODS The study comprised patients with vault or skull base fracture adjacent to a DVS who were admitted to 1 medical center during a 2-year period. The medical records were reviewed for the clinical and radiographic characteristics. All patients had undergone CTV to evaluate potential DVS pathology. The clinical and radiological findings of the patients with DVS pathology were compared with those of the patients with normal DVS. The groups were compared using the chi-square and t-tests for categorical and continuous data, respectively. The potential risk for poor outcome among the patients with DVS pathology was also investigated. RESULTS Of 434 patients with skull fractures, 41 (9.4%) had fractures adjacent to a DVS. DVS pathology was detected in 51% of patients (21 of 41 patients). For 9 (43%) patients, obstruction was extraluminal without thrombosis, and 12 (57%) patients had dural sinus thrombosis (DST). In patients with a positive-CTV scan, the severity of injury according to the Glasgow Coma Scale score at presentation was correlated with the presence of DST (p = 0.007). The sensitivity of noncontrast CT (NCCT) for DVS involvement was 38% among the patients with positive-CTV scans. For patients with DVS pathology, poor outcome was correlated with DST (intraluminal), rather than extraluminal obstruction without thrombosis (p = 0.02), and superior sagittal sinus (SSS) involvement (p = 0.05). CONCLUSIONS NCCT is not sensitive enough to detect DVS obstruction in patients with skull fracture adjacent to a DVS, and CTV should be performed in order to rule it out. A correlation was found between the severity of injury and the presence of DST, rather than extraluminal obstruction. The authors' findings

    A 38-year-old male slipped accidentally and fell from a height of 4.6 m, and was admitted to a hospital. A radiograph indicated a linear fracture of the parietal bone across the sagittal sutura, and a computed tomography scan of the head showed severe subdural hematoma on both parietal sides, so an operation was performed to remove the hematoma. Five hours after the operation, brain death due to a cerebral herniation occurred, and he died six days later. Autopsy revealed a linear fracture of the parietal bones, which crossed obliquely the sagittal sutura. A slightly lacerated wound of the dura mater was seen on the sagittal sutura, from where the latter half of that point to the left and right transverse sinuses were occluded completely with thrombosis. The brain was markedly swollen. From these findings, the victim was considered to have died from acute cerebral swelling due to traumatic thrombosis of the superior sagittal sinus.

    Dural sinus malformations (DSM) are rare malformations mainly reported after birth. The objectives of this study are to describe their prenatal patterns and to focus on their possible favorable outcome. This multicenter retrospective study reported 13 cases of DSM prenatally diagnosed. The admission criterion was a dural mass posterior to the vermis. In 12 patients, MRI was performed after US. Follow-up in 10 born babies (mean: 8 months) and three neuropathological examinations were available. In all fetuses, DSM presented as a well-delimited round mass involving the torcular. The follow-up examinations (n = 10) revealed progressive thrombosis of the DSM marked by a heterogeneous pattern (US and MRI) with concentric rings. The volume of the mass decreased, with complete regression in seven patients (five before and two after birth). One child died at the age of 5 months in the context of major hydrocephalus and another developed atrophy of the frontal lobes. The eight other babies were doing well (5 days to 3 years) without any treatment (n = 6) or following treatment for hydrocephalus (n = 2). Prenatal DSM may have a typical MR pattern, and the prognosis might not be as bad as has previously been reported. In the absence of criterion to predict the hydrovenous cerebral imbalance, it is mandatory to check the parenchyma and the ventricles during the pregnancy. (orig.)

    Background: We report the recovery of ophthalmoplegia in 11 patients with cavernous sinus dural arteriovenous fistula (CSDAVF) after sinus packing at follow-up. Methods: Of 18 patients with CSDAVF treated with transvenous cavernous sinus packing between August 2002 and December 2007 at Beijing Tiantan Hospital, there were 9 patients with initial CNIII or CNVI dysfunction and 2 patients with CNVI dysfunction immediately after cavernous sinus packing selected and reevaluated. Results: Of 11 patients with CNIII or CNVI palsy, recovery was complete in 10. In 1 patient, complete CNVI palsy was unchanged because the CSDAVF was not cured. There were 6 men and 5 women with a mean age of 52.9 years. In 5 patients, CNVI palsy was associated with chemosis, proptosis and pulsatile tinnitus. Timing of treatment after onset of symptoms was from 4 to 35 days in 9 patients. All CSDAVFs were Barrow type D. Mean follow-up after treatment was 17.7 months (range, 2-54 months). Conclusion: CSDAVF-induced CNIII or CNVI palsies can be cured after cavernous sinus packing transvenously in most patients.

    Dural cavernous sinus fistulas (DCSFs) represent a benign vascular disease, consisting in an arteriovenous shunt at the cavernous sinus. In the absence of spontaneous resolution, the fistula may lead to eye redness, swelling, proptosis, chemosis, ophthalmoplegia and visual loss. Although modern imaging techniques have improved the diagnostic, patients with low-flow DCSFs are still misdiagnosed. These patients can get erroneously treated for infections and inflammation for months or years and are at risk of visual loss. Early and proper diagnosis helps to avoid deleterious clinical course of the disease. This volume provides a complete guide to clinical and radiological diagnosis as well as to therapeutic management of DCSF with emphasis on modern minimal invasive treatment options. It commences with an informative description of relevant anatomy. After sections on the classification, etiology and pathogenesis of DCSF, the clinical symptomatology of the disease is described in detail. The role of modern non-invasive imaging tools is then addressed with the use of computed tomography, magnetic resonance imaging and ultrasound. Intra-arterial digital subtraction angiography (DSA), although invasive, remains the gold standard and is mandatory for clinical decision-making and strategy in endovascular treatment. Hence, a throughout consideration is given to both, 2D-DSA and 3D rotational angiography, including recent technological advancements such as Dual Volume (DV) imaging and angiographic computed tomography (ACT). After a short section on arteriovenous hemodynamics, the therapeutic management of DCSFs is described in detail. In particular, various transvenous techniques, required for successful endovascular occlusion of DCSF, are discussed in depth. This well-illustrated volume will be invaluable to all who may encounter DCSF in their clinical practice. (orig.)

    Full Text Available Lateral sinus thrombosis (LST is usually occurs as a complication of middle ear infection .The involvement of lateral sinus during the course of ear infection was a well known complication in preantibiotic days .The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment. Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.

    Cavernous sinus (CS) dural arteriovenous fistulas (DAVFs) rarely cause venous infarction (VI) and/or intracranial hemorrhage (ICH) despite the presence of cortical venous drainage (CVD). The present study investigated the characteristics of CS DAVFs manifesting as VI/ICH. Fifty-four patients treated for CS DAVFs were retrospectively studied. Six patients presented with VI/ICH. Two of the three patients presenting with ICH had CVD only to the superficial sylvian vein (SSV) or the deep sylvian vein (DSV). Three patients presenting with VI had multiple drainages, and angiography of these patients showed a varix on the SSV, drainage into the DSV with agenesis of the second and third segment of basal vein of Rosenthal, and thrombosis of the distal petrosal vein. CS DAVF with CVD only carries higher risk of VI/ICH than multiple drainages. Many CS DAVFs presenting with VI, especially those with drainage into the petrosal vein, have multiple drainages in the early stage. Thrombosis of the inferior and superior petrosal sinuses and superior orbital vein gradually increases pressure of the CVD, and then, VI may occur. In contrast, CS DAVFs with CVD only from the beginning, common in the patients with drainage into the SSVs and DSVs, are likely to cause ICH. Angiographic risk factors causing VI/ICH are CVD only, varix formation, agenesis of the second and third segment of basal vein of Rosenthal, and thrombosis of the superior orbital vein, lateral half of the superior petrosal sinus, and distal CVD.

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    Nephrotic syndrome causes a hypercoagulable state, leading to both venous and arterial thrombosis. The mechanisms are as yet unclear, but numerous alterations in coagulant and anti-coagulant factors have been reported [Llach et al. 1985, Harris and Ismail 1994]. The most common clinical features in adults are renal vein thrombosis, femoral vein thrombosis and pulmonary embolism, although thrombosis in numerous other arterial and venous sites has been described [Cameron 1984, Llach et al. 1985]. Intracranial thrombosis is rare, although in adult nephrotic syndrome arterial thrombosis is well recognized [Fuh et al. 1991]. We report a patient with minimal change nephrotic syndrome who developed venous sinus thrombosis detected by magnetic resonance (MR) scanning.

    2001-08-01

    We report six cases of transverse-sigmoid dural arteriovenous fistulae (TS DAVF) treated with percutaneous transvenous embolisation through the occluded sinus. All patients had sinus occlusive lesions: an isolated sinus in five cases and a distal occlusion of the affected sinus in one. Leptomeningeal retrograde venous drainage via the vein of Labbe or the sylvian vein was observed in all patients with an isolated sinus. In five patients a microcatheter was easily passed through the occluded sinus. In four of them, a complete angiographic cure was achieved by packing the sinus with coils. However, in one, sinus packing was ineffective and surgical excision of the affected sinus was necessary. The microcatheter could not be passed through the occluded sinus in one case, and direct packing of the isolated sinus was later required. In all cases, complete cure was achieved without complications. This safe, not very invasive and highly effective treatment for TS DAVF with sinus occlusion is thus worth trying when the occluded segment is relatively short. (orig.)

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

    Infantile dural arteriovenous fistula is a rare cerebrovascular malformation carrying a poor prognosis with an anatomic cure of only 9%. Endovascular embolization is mainly selected to treat this entity, aiming to obtain normal development of the patients. We present a case of a 20-month-old girl with epilepsy. Digital subtraction angiography revealed a dural arteriovenous fistula involving the right transverse sinus. The arteriovenous fistula was fed by multiple dural branches from the middle meningeal, occipital, meningohypophyseal, and anteroinferior cerebellar arteries. The right transverse sinus was transvenously embolized with platinum coils. Although the shunt flow remained, the patient was liberated from epilepsy. Nine months later, the patient suffered from a recurrence of epilepsy. Digital subtraction angiography demonstrated some increase in shunt flow. Right middle meningeal, occipital, posterior deep temporal, and tentorial arteries were transarterially embolized using N-butyl cyanoacrylate, followed by complete surgical resection of the right transverse sinus. The shunt flow disappeared after surgery, and her epilepsy improved significantly. Our experience suggests that the combination of endovascular and surgical treatment is effective for recurrent infantile dural arteriovenous fistula.

    Full Text Available Cerebral venous sinus thrombosis is a rare form of stroke caused by thrombosis in venous sinuses of the brain. In this study, we reported on a patient with venous sinus thrombosis and brucellosis who presented with uncontrolled seizure despite being treated with anti-epileptic drugs at high doses. The case was a 33-year-old woman with a history of controlled complex partial seizure who presented with headache, asthenia, and uncontrolled seizure for one month. She was febrile and a brain CT scan indicated hemorrhagic focus in the left posterior parietal and the temporal lobe. Magnetic resonance imaging and magnetic resonance venography also proved venous sinus thrombosis in the left transverse sinus. Besides [In addition], a laboratory assessment confirmed brucellosis. Following the treatment with anti-coagulant, anti-brucellosis, and anti-epileptic agents, the patient was discharged in good condition with medical orders. Clinical suspicion and accurate evaluation of a patient′s history is the most important clue in diagnosis and treatment of brucellosis and cerebral venous sinus thrombosis, especially in uncontrolled seizure in patients who had previously been under control.

    Objective: To report our findings concerning the laterocavernous sinus (LCS) drainage of dural fistulas, focusing our attention on the important implications in treatment of the LCS, which is one of the principal drainage pathways of the superficial middle cerebral vein (SMCV). Methods: Consecutive 32 patients with dural fistulas treated endovascularly between 2005 and 2008 were reviewed. Seven patients had angiographic features such as dural fistulas draining with SMCV via LCS. Clinical records for these 7 patients were focused to determine their presenting symptoms, angiographic features, endovascular treatments, and clinical outcomes. Results: Over 3 years, 7 patients had 7 dural fistulas drained with SMCV via LCS were treated. Six-vessel angiography confirmed the presence of the dural fistulas. All fistulas were Cognard Type III featured by leptomeningeal veins drainage. One fistula involving the lesser sphenoid wing and 6 fistulas involving CS were supplied by external carotid artery branches with or without dural branches of the internal carotid artery. LCS was identified as a contiguous to SMCV drainage in these cases. One patient was treated with transvenous coil embolization alone, two with transvenous a combination of Onyx and coil embolization, and 4 with transarterial embolization. An angiographic obliteration and clinical cure was achieved in all patients. Complication was local hair loss due to X-ray radiation in one patient. Conclusion: It is very important to diagnose the presence of LCS in dural fistulas during the diagnostic angiography. It is believed that the knowledge of LCS might be relevant for the understanding and treatment of dural fistulas involving the LCS.

Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic, etiologic, radiological and prognostic characteristics were evaluated. Results: The patients' mean age was 34.01±10.25. Eighty seven (70.16% were women and 37 (29.83% were men. The most frequent clinical manifestations were headache, papilledema and seizures. Fifty seven (65.51% women took oral contraceptive pills. Twenty of 57 women (35.08% took the pill longer than one month to be able to fast in Ramadan or perform the Hajj ceremonies. In the mean time they developed cerebral venous-sinus thrombosis. Superior sagital sinus, with or without lateral sinuses, was the most involved area (70.96%. High mortality and morbidity rates (14.51% and 35.48%, respectively were found in patients. Poor prognostic factors at the time of admission were stupor and coma (P=0.001 and evidence of hemorrhage in primary CT scan (P=0.005. Conclusion: Taking oral contraceptive pills was a main factor associated with cerebral venous-sinus thrombosis. Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Health care policy makers should design a plan to warn susceptible women of the risk of cerebral venous-sinus thrombosis, and to educate them the ways to prevent it

    Introduction: The purpose of this study was to evaluate the single-centre experience with transvenous coil treatment of dural carotid-cavernous sinus fistulas. Methods: Between November 1991 and December 2005, a total of 141 patients (112 female) with dural carotid-cavernous sinus fistula underwent 161 transvenous treatment sessions. The patient files and angiograms were analysed retrospectively. Clinical signs and symptoms included chemosis (94%), exophthalmos (87%), cranial nerve palsy (54%), increased intraocular pressure (60%), diplopia (51%), and impaired vision (28%). Angiography revealed in addition cortical drainage in 34% of the patients. Partial arterial embolization was carried out in 23% of the patients. Transvenous treatment comprised in by far the majority of patients complete filling of the cavernous sinus and the adjacent segment of the superior and inferior ophthalmic vein with detachable coils. Complete interruption of the arteriovenous shunt was achieved in 81% of the patients. A minor residual shunt (without cortical or ocular drainage) remained in 13%, a significant residual shunt (with cortical or ocular drainage) remained in 4%, and the attempted treatment failed in 2%. There was a tendency for ocular pressure-related symptoms to resolve rapidly, while cranial nerve palsy and diplopia improved slowly (65%) or did not change (11%). The 39 patients with visual impairment recovered within the first 2 weeks after endovascular treatment. After complete interruption of the arteriovenous shunt, no recurrence was observed. The transvenous coil occlusion of the superior and inferior ophthalmic veins and the cavernous sinus of the symptomatic eye is a highly efficient and safe treatment in dural carotid-cavernous sinus fistulas. In the majority of patients a significant and permanent improvement in clinical signs and symptoms can be achieved. (orig.)

    The objective of this study was to explore the volumetric alterations of dural sinuses in patients with idiopathic intracranial hypertension (IIH). Standardized cranial magnetic resonance imaging (MRI) was used in 17 patients prior to and following treatment of IIH and in seven controls. Magnetic resonance venographies (MRV) were employed for (a) judgement of circumscript dural sinus stenoses and (b) computation of sinus volumes. Cross-sectional areas (CSA) of the superior sagittal sinuses (SSS) were measured on T2-weighted images. Results of the initial MRIs were compared to those on follow-up MRIs and to results of controls. Stenoses of the transverse sinuses (TS) resulting in cranial venous outflow obstruction (CVOO) were present in 15/17 (88%) patients, normalizing in 7/15 cases (47%) after treatment of IIH. CVOO was not detected in the control group. Segmentation of MRV revealed decreased dural sinus volumes in patients with IIH as compared to controls (P = 0.018). Sinus volumes increased significantly with normalization of intracranial pressure independent from disappearing of TS stenoses (P = 0.007). The CSA of the SSS were normal on the initial MRIs of patients with IIH and increased on follow-up after treatment (P < 0.001). However, volumetries displayed overlap in patients and controls. Patients with IIH not only exhibit bilateral stenoses of the TS as has been reported, but volume changes of their entire dural sinus system also occur. The potential etiopathological and diagnostic roles of these changes are discussed. (orig.)

    A 76-year-old woman presented with an acute onset of right periocular pain, diplopia, ocular injection, progressive proptosis, and periocular swelling. She had an unremarkable past medical history, and the erythrocyte sedimentation rate and complete blood count were normal. A carotid-cavernous sinus fistula was suspected, and an MRI demonstrated enlargement of the superior ophthalmic vein posterior to the globe and enlargement of the inferior ophthalmic vein throughout its entire course. Cerebral arteriography demonstrated a dural cavernous sinus fistula. The inferior ophthalmic vein was accessed via the inferonasal orbital space and was catheterized for delivery of multiple platinum coils to the cavernous sinus fistula. Follow-up venograms demonstrated occlusion of the fistula. At 2-month follow-up, there was a residual sixth nerve palsy and resolution of symptoms, including proptosis and periocular swelling.

    This study aimed to evaluate the safety and efficiency of the endovascular treatment of transverse-sigmoid sinus dural arteriovenous fistulas (TS{sub d}AVF). A total of 150 consecutive patients and 348 procedures were evaluated. Pulsatile tinnitus (81%), headache (15%), and intracranial hemorrhage (10%) were the most frequent manifestations of the TS{sub d}AVFs. More than half of the affected sinuses were partially or completely thrombosed. Access-wise treatment was performed transarterial (n = 33), transvenous (n = 21), or a combination thereof (n = 96). A mean of 2.4 procedures per patient was required. Immediate postprocedural occlusion rate after transarterial embolization was 30% only. Transvenous treatment alone resulted in an early occlusion rate of 81%, with delayed complete obliteration of half of the remaining fistulas. After combined transarterial/transvenous treatment, the angiographic cure rate was 54%. At follow-up, 88% of patients with residual shunt after the treatment showed complete occlusion. The cumulative complication rate was 9% (n = 13), with minor adverse events in ten patients (7%) and major complications in three patients (2%). Transvenous coil occlusion of the sinus segment with the adjacent dAVF site, eventually combined with transarterial occlusion of supplying arteries, is a very effective and well-tolerated treatment method. In selected patients, variations of these methods (e.g., sinus stenting, compartmental sinus occlusion) can be useful. (orig.)

    In a patient with progressive ophthalmological problems, including uncontrolled intraocular pressure related to a cavernous sinus dural arteriovenous fistula, urgent intervention may be necessary to prevent permanent visual loss. We report a case in which inadequate transarterial embolisation and lack of access for transvenous catheterisation, including a direct approach through the superior ophthalmic vein, preceded percutaneous puncture of the superior ophthalmic vein deep within the orbit, permitting venous occlusion without complications. This case demonstrates that deep orbital puncture of the vein is feasible for occlusion of a cavernous sinus dural arteriovenous fistula. (orig.)

    Septic cavernous sinus thrombosis, a relatively uncommon disease entity, frequently can be fatal. Early diagnosis is imperative in order that appropriate treatment be instituted. A 59-year-old woman who was admitted to our institution with complaints of diplopia, blurred vision and fevers that developed following a tooth extraction is presented. Initial CT and lumbar puncture on the day of admission were totally normal. A repeat CT performed 48 hours after admission, on the same day as gallium imaging, demonstrated findings consistent with cavernous sinus thrombosis. Gallium imaging demonstrated intense uptake in the left cavernous sinus and left orbit as well as moderately increased activity in the right cavernous sinus and orbit, confirming infection. The patient was treated with antibiotics, and repeat CT and gallium imaging were performed ten days later, both of which demonstrated near total resolution of the disease process. Conceivably, if gallium imaging had been initiated on the day of admission it may have been the first study to demonstrate an infectious process in the cavernous sinus. Gallium imaging should be considered as a diagnostic tool in the noninvasive workup of this entity.

    Full Text Available Cerebral Venous Thrombosis ( CVT is a multifactorial condition which is described as idiopathic in 12.5% of patients. Hyperthyroidism has been associated with CVT in many case reports, and increased levels of factor VIII and von Willebrand factor (vWF have been proposed as the possible link in this association, but only few rare case reports have described an association of hypothyroidism with CVT. We report here a case of autoimmune thyroiditis presenting with CVT.

    An alert and oriented 27-year-old African American woman with AIDS presented with a 10-day history of fever, cough productive of yellow sputum, nausea, and vomiting and a 1-day history of excruciating headache and photophobia. Her condition rapidly deteriorated into a coma with decorticate and then decerebrate posture, and she died 3 weeks later. There was evidence of extensive intracranial venous sinus thrombosis (ICVST), renal vein thrombosis (RVT), and multiple cerebral hemorrhagic infarcts due to a hypercoagulable state complicating AIDS-associated nephrotic syndrome. This is the first reported case of fatal ICVST and RVT with extensive cerebral hemorrhagic infarcts complicating nephrotic syndrome in a patient with AIDS.

    Full Text Available OBJECTIVE: The aim of this article is to point out the etiology, risk factors, the rate of recanalization and mortality of cerebral venous sinus thrombosis patients. METHODS: The current study was planned as retrospectively and fifty patients were included. All the patients were analyzed according to the clinical presentation, etiologic causes, risk factors, presence of MR lesion, the involvement of anatomic localization, recanalization and mortality. RESULTS: The most frequent risk factors of the cases were prothrombotic conditions (34%, pregnancy (14% and puerperium (8%. The most frequent involvement was transverse sinus and secondly more than one sinüs thrombosis. As clinical application symptoms we detected headache (68% and then focal neurologic deficiency (30%. On the other hand, at least 3 month’s incidence rate of recanalization in the patients was 70.7%. Except for 2 cases that ended with death, the mortality of the cases was low. We could not find a significant association between risk factors and the presence of cerebral MR lesion or not (p=0.42 and also the presence of recanalization or not in the follow-up MR venography (p=0.625. CONCLUSION: We have concluded that, in the diagnosis and follow-up of cerebral venous sinus thrombosis, MR venography is the best method; through early diagnosis and proper treatment, the rate of recanalization will be fairly high and mortality will be low. In etiology, besides trombotic conditions, pregnancy and puerperium must be considered as one of the frequent risk factors.

    Full Text Available La trombosis de los senos venosos durales es una rara y devastadora enfermedad. Se presenta generalmente en mujeres y ancianos, y no es frecuente en niños, aunque se reconoce ya como una causa de morbilidad y mortalidad en la población pediátrica. Se han reportado pocos casos en el mundo de neonatos afectados por esta entidad, en su mayoría fatales e insuficientemente investigados. A continuación se presenta el caso de un recién nacido con una trombosis del seno sagital que sobrevivió. Los factores predisponentes para la aparición de la enfermedad en este caso fueron la asfixia neonatal, la deshidratación severa unida al uso de una línea venosa central, y la inmovilización prolongada. Aunque la TAC contrastada no es el estudio ideal para su diagnóstico, permitió realizarlo oportunamente en este caso. El tratamiento temprano con anticoagulantes permitió una rápida recuperación y favoreció la recanalización venosa del seno involucrado. Hasta el momento no se han detectado secuelas neurológicas y el paciente tiene buen desarrollo psicomotor.Dural venous sinus thrombosis is a rare devastating disease. It is generally found in females and old people, but is infrequent in children; however, it is already recognized as a morbidity and mortality cause in the pediatric population. Few cases of newborns with this disease have been reported worldwide; most of them were poorly studied and had fatal outcomes. Here is the presentation of a newborn with sagittal sinus thrombosis, who managed to survive. The predisposing factors for the disease were neonatal asphyxia, severe dehydration together with the use of central venous line and extended immobilization. Although contrast CAT is not the ideal study, it helped to promptly arrive at the right diagnosis in this case. The early treatment based on anticoagulants allowed rapid recovery and facilitated venous retaking of the involved venous sinus. No neurological sequels have been so far

    A 4-month-old female presented with a dural arteriovenous fistula (DAVF), which was successfully managed using endovascular techniques. There are very few case series reporting DAVF in infants younger than 12 months and, to our knowledge, only 60 pediatric patients with DAVF have been reported to date. Although most DAVF have a benign course, they can result in life-threatening hemorrhage. Endovascular therapies are usually indicated in the management of these neurosurgical vascular malformations. Endovascular therapy of DAVF in neonatal patients presents some major issues. Gaining arterial access may be problematic in femoral arteries too small for the introduction of a sizeable guiding catheter. The volumes of contrast and infused fluids must be carefully monitored to prevent fluid overload. Radiation exposure should be restricted as far as possible. This report contributes to the limited body of evidence on neonatal DAVF and its endovascular management. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Cerebral venous thrombosis (CVT is uncommon after cesarean section. Although it can be a leading cause of maternal mortality. CVT may occur during pregnancy because of hypercoagulable states such as preeclampsia, thrombophilias, antiphospholipid antibody syndrome and sepsis.Case presentation: A 31 years old woman G2 Ab1 at 37 weeks gestational age with  premature rupture of membrane underwent cesarean section because breech presentation and preeclampsia. Spinal anesthesia was done for emergent cesarean section. On the second day after cesarean section, she developed headache, vomiting, focal neurologic deficits, paresthesia, blurred vision. Brain magnetic resonance imaging (MRI showed thrombosis in anterior half of superior sagittal sinus. Treatment consisted of anticoagulation.  Conclusion: Thrombophilias, pregnancy-related hypertension and cesarean section are the predisposing factors for thromboembolism. Unfractionated heparin and low molecular weight heparin (LMWs are effective drugs for thromboprophylaxis. It is vital to prevent venous thrombosis to reduce mortality during both intrapartum and postpartum periods. Consideration of cerebral venous thrombosis in similar cases is recommended.

    To determine frequency, imaging features and clinical significance of herniations of brain parenchyma into dural venous sinuses (DVS) and/or calvarium found on MRI. A total of 6160 brain MRI examinations containing at least one high-resolution T1- or T2-weighted sequence were retrospectively evaluated to determine the presence of incidental brain herniations into the DVS or calvarium. MRI sequences available for review were evaluated according to their capability to demonstrate these herniations. Patients' symptoms and clinical findings were recorded. Twenty-one (0.32 %) brain parenchyma herniations into the DVS (n = 18) or calvarium (n = 3) in 20 patients were detected. The most common locations of the herniations were the transverse sinuses (n = 13) and those involving inferior gyrus of the temporal lobe (n = 9). High-resolution T1- and T2-weighted sequences were equally useful in the detection of these brain herniations. According to clinical symptoms, brain herniations were considered to be incidental but headaches were present in nine patients. Brain herniations with surrounding cerebrospinal fluid (CSF) into the DVS and/or calvarium are incidental findings and not proven to be associated with any symptoms. Although rare, these herniations are more common than previously recognized and should not be confused with arachnoid granulations, clots or tumours. (orig.)

    Full Text Available Abstract Introduction Cerebral venous sinus thrombosis is a rare condition. The most frequent symptoms and signs are headache, focal seizures with or without secondary generalization, unilateral or bilateral paresis and papilledema. We report a case of transverse sinus and superior sagittal sinus thrombosis that presented with diplopia in a pregnant woman. Case presentation A 34-year-old Malay woman, gravida 3 para 2 at 8 weeks of pregnancy, was admitted for hyperemesis gravidarum, presented with sudden onset of diplopia, blurring of vision and headache. A magnetic resonance scan of her brain showed the presence of cerebral edema with no space occupying lesion, but magnetic resonance venography ultimately revealed right transverse sinus and superior sagittal sinus thrombosis. The patient was treated with anticoagulation for 1 year, after which the patient recovered fully. Conclusion Due to its diverse and varied neurological presentation, cerebral venous sinus thrombosis should be considered in almost any brain syndrome.

    Sinus thrombosis has rarely been associated with closed head injury; more often, thrombosis of the sigmoid or transverse sinus is caused by otogenic inflammations or tumours, or occurs during pregnancy. Symptoms are frequently vague, while untreated thrombus progression may be fatal due to venous congestion and infarction. We report a 32-year-old man presenting with right hearing loss, tinnitus and headache 2 days after a closed head injury. Neurological examination showed no additional abnormality. The EEG showed focal bifrontal slowing. CT revealed a fracture of the occipital bone. MRI and MRA demonstrated complete thrombosis of the right sigmoid and transverse sinuses. After 2 weeks of intravenous heparin therapy followed by warfarin, the patient's hearing improved and MRI and MRA showed complete recanalisation of the sigmoid and transverse sinuses. Venous sinus thrombosis can be an undetected sequel to head injury. Appropriate imaging studies should be carried out to enable therapy to be started as soon as possible. (orig.)

    Whilst cerebral vascular disease and mental illness in the post-partum period are well recognised, their co-existence and the concept of organic psychoses in pregnancy, parturition and the puerperium remains poorly appreciated (Brockington 2006; Brockington Arch Women's Ment Health 10: 177-178, 2007a; Brockington Arch Women's Ment Health 10: 305-306, b). We report a woman who was referred to the Medical team on-call with a mixed presentation of euphoria, mutism and aggressive behaviour but ultimately demonstrated to have a transverse sinus thrombosis and recovered well with anti-coagulation. This serves an important reminder of the implications of a missed medical diagnosis in this high-risk and vulnerable group of patients.

    Variations in cerebral venous development can influence the ability to regulate drainage. In cerebral sinovenous thrombosis, these variations can be associated with elevated intracranial pressure. We present a series of pediatric patients with unilateral cerebral sinovenous thrombosis and investigate whether the contralateral venous sinus size increases the risk of developing elevated intracranial pressure. Patients diagnosed with a unilateral cerebral sinovenous thrombosis were identified by querying our institutional radiology data base. The difference in the occurrence of elevated intracranial pressure in patients with cerebral sinovenous thrombosis with and without hypoplastic venous sinuses was studied. Twelve cases of unilateral cerebral sinovenous thrombosis met the inclusion criteria and had sufficient images. Six patients had hypoplastic contralateral venous sinuses. The presence of hypoplastic contralateral venous sinus in the setting of thrombosis of a dominant sinus was associated with elevation of intracranial pressure (83% versus 0%, P = .015). Patients with cerebral sinovenous thrombosis and contralateral hypoplastic venous sinuses are at higher risk of developing elevated ICP and may benefit from screening with an ophthalmologic examination.

    OBJECTIVE Surgical simulation has the potential to supplement and enhance traditional resident training. However, the high cost of equipment and limited number of available scenarios have inhibited wider integration of simulation in neurosurgical education. In this study the authors provide initial validation of a novel, low-cost simulation platform that recreates the stress of surgery using a combination of hands-on, model-based, and computer elements. Trainee skill was quantified using multiple time and performance measures. The simulation was initially validated using trainees at the start of their intern year. METHODS The simulation recreates intraoperative superior sagittal sinus injury complicated by air embolism. The simulator model consists of 2 components: a reusable base and a disposable craniotomy pack. The simulator software is flexible and modular to allow adjustments in difficulty or the creation of entirely new clinical scenarios. The reusable simulator base incorporates a powerful microcomputer and multiple sensors and actuators to provide continuous feedback to the software controller, which in turn adjusts both the screen output and physical elements of the model. The disposable craniotomy pack incorporates 3D-printed sections of model skull and brain, as well as artificial dura that incorporates a model sagittal sinus. RESULTS Twelve participants at the 2015 Western Region Society of Neurological Surgeons postgraduate year 1 resident course ("boot camp") provided informed consent and enrolled in a study testing the prototype device. Each trainee was required to successfully create a bilateral parasagittal craniotomy, repair a dural sinus tear, and recognize and correct an air embolus. Participant stress was measured using a heart rate wrist monitor. After participation, each resident completed a 13-question categorical survey. CONCLUSIONS All trainee participants experienced tachycardia during the simulation, although the point in the simulation

    Objective: To explore and evaluate the efficacy of intrasinus thrombolysis (IST) in patients with cerebral venous sinus thrombosis (CVST) during postpartum period. Methods: 11 patients during postpartum period with CVST who received IST during July 2007–November 2011 were included. Urokinase was infused into the sinuses via a microcatheter. Magnetic resonance venography (MRV) was performed to assess the recanalization of venous sinuses. Results: Before discharge, the intracranial pressure in 11 patients was under 200 mmH{sub 2}O. MRV confirmed that venous sinus of 9 patients were smooth. The cortex venous and deep venous recovered to normal. Venous sinus of 2 patients recanalized partly, and cortex venous and deep venous had compensation. 9 patients had good outcome and 2 patients had only mild deficits. Conclusion: Intrasinus thrombolysis is safe and effective in patients with severe cerebral venous sinus thrombosis during postpartum period.

    Full Text Available Background Cerebral venous sinus thrombosis (CVST is a special type of cerebrovascular disease with high morbidity and mortality which often has an unpredictable outcome. It is usually misdiagnosed because of different causes and variable clinical manifestations. How to improve the diagnosis and therapy of CVST is always the hotspot in clinic. This article aims to investigate the effective and safe strategies in the treatment for CVST. Methods Clinical data of 52 patients diagnosed with CVST were retrospectively analyzed. These patients were subdivided into mild type and severe type according to the features of symptoms, signs, lumbar puncture pressure and imaging. The patients with mild type were treated with systemic anticoagulant therapy combined with intravenous thrombolysis [continuous intravenous infusion of heparin (12.50-25 × 103 U/d for 7-10 d followed by a continuous infusion of urokinase (0.50-0.75 ×106 U/d for 5-7d]. The patients with severe type were treated with endovascular thrombolysis [injection of urokinase (0.50-1 × 106 U, 0.10 × 106 U/min via carotid or vertebral artery; or intravenous infusion of urokinase 1 ×106 U/d and heparin 25 ×103 U/d for 5-7 d], and superior sagittal sinus cut-open/ intrasinus thrombolysis separately. All the patients took oral warfarin for 6-12 months, and follow-up was performed after operation by the method of magnetic resonance venography (MRV. Results Among the 27 cases of mild type receiving systemic anticoagulant agents and intravenous thrombolysis, 14 were cured; 9 were improved; 4 were ineffective. Among the 22 cases of severe type receiving systemic anticoagulant drugs and endovascular thrombolysis, 18 were cured; 3 were improved; 1 was dead. The left 3 cases with gravis type received superior sagittal sinus cut-open/intrasinus thrombolysis and were cured. The period of follow-up was between 6 months and 60 months (the median time was 36 months, and no recurrence happened. Conclusion

    Full Text Available We report a 20-year-old woman with sickle cell disease (SCD who presented with a severe pulsating headache, nausea, and vomiting. Her history was significant for a past thrombotic event during which she had not used anticoagulation therapy as prescribed. Her mental status was mildly confused. On funduscopic examination, papilledema and retinal hemorrhages were found. Results of a computed tomogram were normal. A lumbar puncture demonstrated increased intracranial pressure (60 cm H2O. Magnetic resonance venography demonstrated a right sigmoid sinus thrombosis. Although SCD has been reported as a cause of thrombotic dural venous sinus events, this case increases the knowledge about neurological complications of SCD. The patient was treated with low molecular weight heparin, blood transfusions, acetazolamide, and methylprednisolone, and her symptoms and signs resolved.

    An 62-year-old man presented visual impairment and generalized seizure. Brain CT performed on the day of admission showed thrombus in the right transverse sinus, and DWI showed high intensity areas in the bilateral occipital and parietal lobes. According to bilateral occipital lobe lesions, we considered his visual impairment as cortical blindness. He was diagnosed as venous sinus thrombosis and intravenous heparin, edaravone and osmotic diuretics were administered. MR venography performed after starting of intravenous treatment showed flow gap in the left transverse sinus but no abnormalities in the right transverse sinus. On the second day of hospitalization, his cortical blindness showed improvement and thrombus in the right transverse sinus were disappeared. This indicated that his left transverse sinus originally hypoplastic, thrombus and hemostatis in the right transverse sinus (his dominant side) caused his cortical blindness and generalized seizure. There was a recanalization in the right transverse sinus after heparin therapy.

    Inflammatory bowel disease (IBD) is an idiopathic inflammatory disease of the gastrointestinal tract. The pathophysiology of IBD is probably the result of the complex interaction of genetic susceptibility and environmental influences. There is a well-known risk of thrombosis in patients with IBD. We present the case of a 53-year-old man with ulcerative colitis, who spontaneously developed intracranial sinus thrombosis that was treated with low molecular weight heparin. Literature was searched to assess the frequency and characteristics of cerebral sinus thrombosis in IBD and the role of certain etiopathological factors in such thrombotic patients.

    Cerebral sinus-vein thrombosis may lead to severe hemodynamic changes, elevated intracranial pressure (ICP), and brain edema. It is supposed that progression of the thrombus from the sinus into bridging and cortical veins plays a key role in the development of these pathophysiological changes, but this hypothesis lacks experimental proof. The aim of this study, using a novel animal model of sinus-vein thrombosis, was to evaluate the effects of a standardized occlusion of the superior sagittal sinus and its bridging and cortical veins on hemodynamic alterations, on brain water content, and on ICP in domestic pigs. In 10 animals, the middle third of the superior sagittal sinus was occluded with a catheter-guided balloon. Five of these pigs received an additional injection of 1 ml fibrin glue into the superior sagittal sinus anterior to the inflated balloon, leading to an obstruction of bridging and cortical veins. In five control animals the balloon was inserted but not inflated. Five pigs underwent cerebral angiography. Four hours after occlusion, the brains were frozen in liquid nitrogen, and coronal slices were examined for Evans blue dye extravasation, regional water content, and histological changes. Occlusion of the superior sagittal sinus alone did not affect ICP or cerebral perfusion pressure (CPP). The additional injection of fibrin glue caused an obstruction of cortical and bridging veins as well as severe increases in mean (+/- standard deviation) ICP to 49.4 +/- 14.3 mm Hg, compared with 8.3 +/- 4.5 mm Hg in sham-treated controls and 7.1 +/- 3.9 mm Hg in animals with occlusion of the superior sagittal sinus alone. There was also a steep fall in the mean CPP to 34.2 +/- 19.6 mm Hg compared with 96.4 +/- 13.8 mm Hg in the control group. White-matter water content anterior to the occlusion site was elevated to 81.9 +/- 3.7 gm/100 gm frozen weight in the fibrin group as compared to 70.7 +/- 2.2 gm/100 gm in controls. Posterior to the occlusion site, water

    Neonatal cerebral sinovenous thrombosis (CSVT) causes lifelong morbidity. Newborns frequently incur positional occipital bone compression of the superior sagittal sinus (SSS). We hypothesized that SSS compression is associated with neonatal CSVT. Our retrospective case-control study recruited neonates with CSVT (SickKids Children's Stroke Program, January 1992-December 2006). Controls were neonates without CSVT undergoing magnetic resonance or computed tomography venography (institutional imaging database, 2002-2005) who were matched 2 per each case patient. Blinded neuroimaging review by 2 experts quantified SSS compression and head position. Effect of SSS compression on the primary outcome of CSVT was determined (logistic regression). Secondary analyses included the relationship of head position to SSS compression (t test) and group comparisons (cases versus controls, cases with and without compression) for demographic, clinical, and CSVT factors (χ² and Wilcoxon Mann-Whitney tests). Case (n = 55) and control (n = 90) patients had similar ages and delivery modes. SSS compression was common (cases: 43%; controls: 41%). Controlling for gender and head position, SSS compression was associated with CSVT (odds ratio: 2.5 [95% confidence interval: 1.07-5.67]). Compression was associated with greater mean (SD) angle toward head flexion (101.2 [15.0] vs 111.5 [9.7]; P infarction, recanalization, and outcome. Many idiopathic cases had SSS compression (79%). Interrater reliability of compression measurements was high (κ = 0.87). Neonatal SSS compression is common, quantifiable, and associated with CSVT. Optimizing head position and/or developing devices to alleviate mechanical SSS compression may represent a novel means to improve outcomes.

    @@ AIthough recurrent traumatic carotid-cavernous fistula (CCF) and its treatment have been reported sporadically,1 a complex cavernous sinus dural arteriovenous fistula (DAVF) secondary to balloon embolization of a direct traumatic CCF is rare. In 2005, we treated such a case via transvenous approach using coils and N-buty-2-cyanoacrylate (NBCA). The causes of recurrent cavernous sinus DAVF and its endovascular approach are discussed.

    Cerebral venous sinus thrombosis represents less than 1% of all strokes, being an uncommon entity with a wide spectrum of clinical scenarios. We present a 45-year-old Hispanic female with a history of long-term oral contraceptive use who was diagnosed with cerebral venous sinus thrombosis due to a heterozygous carrier mutation in the prothrombin G20210A gene. The patient was successfully managed with intravenous heparin with favorable clinical results without adverse effects. The prevalence of inherited primary thrombophilia increases with additional risk factors such as the use of oral contraceptives that can trigger or prothrombotic events in any vascular bed. An increased prevalence in the prothrombin G20210 gene mutation has been demonstrated in the Mexican-Mestizo population. Controversy exists regarding therapy of cerebral venous sinus thrombosis; according to experts, heparin remains the cornerstone of therapy with acceptable outcomes. More clinical trials are required to evaluate long-term outcomes in this subgroup of patients.

    A 32-years-old man with a past history of hemorrhoids presenting with hemiparesis was diagnosed as having sagittal sinus thrombosis with hemorrtagic infarction. Laboratory data revealed macrocytic anemia (Hb 11.2 g/d/) with hypoproteinernia (5.5 g/d). After discharge the patient developed abdominal pain, diarrhea, edema in the leg and sustained anemia. Final diagnosis through colon fiberscope findings was Crohn's disease Macrocytic anemia seemed to be induced by Vit. B12 deficiency due to malabsorption. The mechanism and causal relationship between Crohn's disease and sinus thrombosis is discussed.

    2016-08-01

    Postdural puncture headache (PDPH) is a feared complication related to epidural steroid injections. We report a unique case in which all subjective and objective findings indicated the diagnosis of PDPH. However, the patient failed appropriate conservative and interventional management. Therapeutic failure prompted further investigation to establish the correct diagnosis of cerebral venous sinus thrombosis. Cerebral venous sinus thrombosis is a rare, difficult to diagnose, but potentially lethal disorder with nonspecific and variable clinical presentations, including headache and focal neurological deficits. Performing magnetic resonance imaging and magnetic resonance venogram should be considered early, especially in patients who fail to respond to standard interventions for PDPH.

    This study sought to elucidate the genetic correlation of cerebral venous sinus thrombosis caused by a hereditary antithrombin deficiency in a Chinese family, at the genetic and protein levels. A nonsense mutation from C to T on locus 6431 in exon 3B of the antithrombin gene was observed,leading to an arginine (CGA) to stop codon (TGA) change in the protein. This is the first report of this mutation in China. Ineffective heparin therapy in the propositus patient is associated with a lack of heparin binding sites after antithrombin gene mutation. Characteristic low intracranial pressure in the acute phase might be specific to this patient with cerebral venous sinus thrombosis.

    The cerebral venous sinus system is a rare site for venous thrombosis except in patients with antiphospholipid syndrome. We describe three patients presenting with cerebral venous thrombosis in association with other thrombotic sites in two patients and as an only site in one patient. Antiphospholipid syndrome has varied clinical manifestations but the defining feature is the persistent presence of antiphospholipid antibodies. In this report we will review the clinical and laboratory diagnostic criteria and the management of patients with antiphospholipid syndrome.

    Full Text Available Background: Estimations of D-dimer correlate with deep vein thrombosis and pulmonary thromboembolism and may serve as a marker of cortical venous sinus thrombosis (CVST. Aim: To study the usefulness of D-dimer in the diagnosis of CVST. Materials and Methods: A total of 26 patients with CVST were subjected to a detailed medical history and neurological evaluation. A cranial MRI was carried out on a 1.5T scanner using T1, T2, and DWI sequences and two-dimensional time of flight MR venography. D-dimer was estimated using a rapid latex agglutination slide test using monoclonal antibodies. Results: The age of patients ranged between 16 and 70 years old (median 31 years old; 8 were males and were examined after a mean duration of 22 days of symptoms. Cortical venous thrombosis was attributed to puerperium in 4 patients, infection in 5 patients, and pregnancy, dehydration, insect bite, and migraine in 1 patient each. Superior sagittal sinus was involved in 15 patients, transverse sinus in 16 patients, straight sinus in 3 patients, sigmoid sinus in 7 patients, and cavernous and deep system in 1 patient each. A total of 12 patients had more than one sinus involvement. D-dimer was positive in 20 patients and correlated with the duration of symptoms but not with the extent of sinus thrombosis and the outcome. Conclusion: D-dimer is useful in patients suspected of CVST and patients with positive test results should be urgently sent for MR imaging.

    To describe the direct percutaneous transorbital puncture technique for embolisation of the selected intraorbital and cavernous sinus dural arteriovenous fistula, which failed to be treated by conventional endovascular techniques. One case of intraorbital and five cases of cavernous sinus dural arteriovenous fistula were embolised through direct percutaneous transorbital puncture in 2012, and the clinical data were reviewed. Under fluoroscopic guidance with a three-dimensional (3D) skull reconstruction overlay, the cavernous sinus or ophthalmic vein was punctured via the superior orbital fissure. Then a microcatheter was inserted via the needle, and Onyx was injected to embolise the fistula with or without a combination of coils. Complete obliteration of the fistula was achieved in all six patients. After operation all the patients experienced transient swelling of the punctured orbit persisting for three to five days. No other complications occurred. Follow-up of six patients at three to six months showed resolution of their initial neuro-ophthalmological symptoms in five and left visual loss in one did not recover. Six months follow-up angiogram showed no recurrence of these fistulas. Direct percutaneous transorbital puncture provides an option for the intraorbital and cavernous sinus dural arteriovenous fistulas, particularly when the conventional transvenous routes are inaccessible. Overlay of the 3D skull reconstruction can facilitate the precise puncture of the superior orbital fissure. © The Author(s) 2015.

    Full Text Available A full-term male neonate from a first pregnancy of two clinical non-consanguineous parents was born at 40 weeks of gestation with cesarean section. He was admitted at 2 hours of life to our III level Neonatal Intensive Care Unit due to generalized hypotonia, presenting at birth. Cerebral ultrasound showed a temporal bilateral aspecific alteration of the parenchimal echogenicity, whereas a magnetic resonance imaging/venography revealed an extensive cerebral sinus thrombus. Extensive diagnostic studies for prothrombotic disorders showed negative results, even if there was an alterated haemostatic screening. Persistency of hypotonia led us to investigate Prader-Willi syndrome among others. Methylation analysis confirmed the diagnosis. This is the third report associating cerebral venous thrombosis and Prader-Willi syndrome, confirming sinus thrombosis as a possible presentation of this syndrome. A review of the literature is provided in order to disclose possible similarities and differences in Prader-Willi syndrome patients with cerebral sinovenus thrombosis.

    Cavernous dural arteriovenous fistula (DAVF), which usually presents with conjunctival injection, proptosis, loss of visual acuity, and ophthalmoplegia, is a rare cause of ophthalmoplegia. Thus, it may be overlooked when the typical symptoms are lacking. There have been some cavernous DAVF case reports presenting with isolated oculomotor, abducens and trochlear nerve palsy. We report a patient presenting with isolated oculomotor palsy, caused by cavernous DAVF, which was treated by transvenous coil embolization. This case suggests that cavernous DAVF should be considered in the differential diagnosis of isolated oculomotor nerve palsy and for which case - selective angiography and embolization may be helpful in reaching a diagnosis and providing a guide for optimal treatment.

    Preeclampsia is a leading cause of maternal mortality and morbidity worldwide. The neurological complications of preeclampsia and eclampsia are responsible for a major proportion of the morbidity and mortality for women and their infants alike. Hormonal changes during pregnancy and the puerperium carry an increased risk of venous thromboembolism including cerebral venous sinus thrombosis (CVST). Factor 5 leiden (FVL) is a procoagulant mutation associated primarily with venous thrombosis and pregnancy complications. We report a patient with FVL mutation who presented with CVST at 24th week of pregnancy and was diagnosed as HELLP syndrome at 34th week of pregnancy.

    Full Text Available Indirect (dural carotid cavernous fistula is formed by the connection between meningeal branches of the internal carotid artery and the cavernous sinüs, and low flow circulation with low pressure is occured. Proptosis, ophtalmoplegia, headache, scleral and conjuctival hyperemia expanding around the eyeball can be observed. A forty-eight year old female patient with a background of diabetes mellitus and hypertension was admitted with complaints of double vision. Isolated oculomotor nerve palsy was found in neurological examination and an indirect carotid cavernous fistula was revealed by digital subtraction angiography. Our case with carotid cavernous fistula as a rare cause of isolated oculomotor nerve palsy is worth to be reported.

    Full Text Available Cerebral venous sinus thrombosis is an uncommon cause of stroke presenting with varied presentation patterns. We report a case of a 21-year-old woman with superior sagittal sinus (SSS thrombosis (SSST developing after childbirth, presenting with visual hallucinations, severe headache, and tonic-clonic seizures. Time-of-flight magnetic resonance angiography (TOF-MRA demonstrated the presence of thrombus in SSS. She was treated with low molecular weight heparin (LMWH followed by warfarin. She had excellent recovery a few weeks after admission and was regularly followed up. Although this condition can be presented with different neurological symptoms, it does not typically present with hallucinations. We suggest that CSVT should be suspected even when a patient presents with an atypical picture in a category of patients at higher risk.

    Background -Transcatheter heart valve (THV) thrombosis has been increasingly reported. In these studies, thrombus quantification has been based on 2D assessment of a 3D phenomenon. Methods -Post-procedural four-dimensional, volume-rendered CT (4DCT) data of CoreValve, Evolut R, and SAPIEN 3 transcatheter aortic valve replacement (TAVR) patients enrolled in the RESOLVE trial were included in this analysis. Patients on anticoagulation were excluded. SAPIEN 3 and CoreValve/Evolut R patients with and without hypo-attenuated leaflet thickening (HALT) were included in order to study differences between groups. Patients were classified as having THV thrombosis if there was any evidence of HALT. Anatomical and THV deployment geometries were analyzed, and thrombus volumes were computed through manual 3D reconstruction. We aimed to identify and evaluate risk factors that contribute to THV thrombosis through the combination of retrospective clinical data analysis and in vitro imaging in the space between the native and THV leaflets (neo-sinus). Results -SAPIEN 3 valves with leaflet thrombosis were on average 10% further expanded (by diameter) than those without (95.5 ± 5.2% vs. 85.4 ± 3.9%; p<0.001). However, this relationship was not evident with the CoreValve/Evolut R. In CoreValve/Evolut Rs with thrombosis, the thrombus volume increased linearly with implant depth (R(2) = 0.7; p < 0.001). This was not seen in the SAPIEN 3. The in vitro analysis showed that a supra-annular THV deployment resulted in a nearly 7-fold decrease in stagnation zone size (velocities less than 0.1 m/s) when compared to an intra-annular deployment. In addition, the in vitro model indicated that the size of the stagnation zone increased as cardiac output decreased. Conclusions -While TAVR thrombosis is a multi-factorial process involving foreign materials, patient-specific blood chemistry and complex flow patterns, our study indicates that deployed THV geometry may have implications on the

    A girl with Down's syndrome, moyamoya disease and sagittal sinus thrombosis is described. She was diagnosed after acute neurological deterioration by MRI and angiography. Recombinant tissue plasminogen activator (r-TPA) was injected locally to recanalise the thrombus. The patient's condition significantly improved and she was discharged. After 2 years of follow-up the child remains asymptomatic. Moyamoya syndrome and cerebral venous thrombosis should not be overlooked as a cause of acute neurological deterioration in a child with Down's syndrome. MRA appears to be a safe and accurate alternative to traditional angiography for the diagnosis of moyamoya disease. Local fibrinolysis with r-TPA is the treatment of choice for cerebral venous thrombosis due to its safety and efficacy. (orig.)

    Full Text Available The association between the progestin only pill used for treatment of menstrual disorders and cerebral venous sinus thrombosis (CVST has rarely been reported in the literature. This report describes a case of cerebral venous thrombosis following intake of norethisterone for menorrhagia secondary to polycystic ovary syndrome in a young woman with undiagnosed underlying hyperhomocysteinemia. A 24 year old married woman presented with acute onset of headache, vomiting and right focal seizures. MRI Cerebral venogram and CT Brain revealed thrombosed anterosuperior segment of superior sagittal sinus and haemorrhagic infarct in right frontoparietal region. The risk factors were acquired hyperhomocysteinemia, polycystic ovary syndrome and norethisterone for menorrhagia. The patient was treated with low molecular weight heparin, followed by warfarin, vitamin B12, vitamin B6 and folic acid. She made a total recovery. Although venous thrombosis is usually linked to the ingestion of estrogen, rather than progestogen, this case illustrates that patients who are prescribed progestogen only pills for gynaecological disorders may develop thrombosis, especially if they have predisposing metabolic disorders.

    2014-01-01

    Full Text Available Background and Purpose: This study aimed to investigate the efficacy and safety of balloon dilatation and thrombus extraction for the treatment of cerebral venous sinus thrombosis (CVST. Materials and Methods: Twenty-six cases of digital subtraction angiography-confirmed CVST were treated with balloon dilatation and thrombus extraction. Active treatment of primary disease was carried out after cerebral venous sinus recanalization, and the subsequent anticoagulant therapy lasted for 6 months. Results: Recanalization of the cerebral venous sinus was achieved in all 26 patients, and no endovascular treatment-related complications occurred during or after the procedure. At discharge, the Glasgow Coma Scale (GCS of the patients had improved from an average of 12.3 points to 15 points, and clinical symptoms were improved in 100% of the patients. Follow-up times ranged from 12-62 months (mean follow-up time of 42.3 months and no thrombus re-formation or new neurological deficits occurred during that time. Conclusion: Based on our small study population, balloon dilatation and thrombus extraction appears to be a safe and effective treatment for cerebral venous sinus thrombosis. However, further research is needed to confirm this.

    2015-12-01

    Aseptic cavernous sinus thrombosis (CST) is rare and may clinically masquerade as a carotid cavernous fistula. Conventional management includes oral anticoagulation, but cases of ocular hypertension affecting vision may require more aggressive intervention. We report a case of a woman with spontaneous bilaterally occluded cavernous sinuses with elevated intraocular pressure (IOP), which resolved immediately following unilateral superior ophthalmic vein (SOV) sacrifice. She was subsequently placed on oral anticoagulants. By 4 months postoperatively her IOP was normalized and her vision had improved. Repeat angiography demonstrated stable venous filling, with some mild improvement of flow through the cavernous sinus. Coil-mediated sacrifice of the SOV might be an effective means to relieve ocular hypertension and preserve vision in the setting of aseptic CST.

    2014-01-01

    Full Text Available Cerebral venous sinus thrombosis (CVST is a relatively rare cerebrovascular disease, of which the risk has been documented in patients with numerous conditions. However, CVST has never been previously described in association with the use of a diagnostic curettage in patient with uterine fibroid. Herein, we described a 43-year-old woman who presented with recurrent convulsive seizures and severe and progressive headache 1 day after a diagnostic curettage of the uterus, which was confirmed to be uterine fibroid pathologically later, and her condition subsequently progressed to confusion. Brain magnetic resonance imaging (MRI revealed an acute extensive thrombosis of the left transverse and sigmoid sinus and the ipsilateral cerebellum infarction. Evaluation for primary thrombophilia revealed that an iron deficiency anemia (IDA due to the fibroid bleeding induced menorrhagia together with a diagnostic curettage might be the sole hypercoagulable risk factor identified. Treatment with anticoagulation led to full recovery of her symptoms and recanalization of the thrombosis was proven on magnetic resonance venography (MRV 2 months later. We suggest that CVST should be recognized as a potential complication related to this diagnostic technique, especially in patient with IDA. The early diagnosis and timely treatment would be of significance in improving the prognosis of this potentially lethal condition.

    Ellen Hermans

    2011-09-01

    Full Text Available Cerebral venous thrombosis (CVT is a distinct cerebrovascular condition that represents 0.5–1% of all strokes in the general population. Because of its procoagulant and antifibrinolytic effects [Horne et al.: J Clin Endocrinol Metab 2004;89:4469–4473], hyperthyroidism has been proposed as a predisposing factor for CVT [Saposnik et al.: Stroke 2011;42:1158–1192]. For the first time, we describe a 22-year-old right-handed woman with a sinus sigmoideus thrombosis due to Graves’ disease. Although subclinical hyperthyroidism had been detected 2 years before the onset of neurological symptoms, she did not receive any medical follow-up. Early recognition, diagnosis and treatment are of crucial importance, as Graves’ disease is a risk factor for CVT and stroke.

    Full Text Available Lateral sinus thrombosis (LST is a rare complication of Acute Otitis Media and associated mastoiditis. Although, in the era of antibiotics, the presentation may be variable and diagnosis is difficult. High index of suspicion is required to diagnose the atypical presentation. We report an atypical presentation of LST wherein a 12-year-old female presented with sudden onset severe occipital headache following ear syringing. Contrast enhanced computed tomography of temporal bone revealed LST without coalescent mastoiditis. Patient was managed conservatively with intravenous antibiotics and low-dose heparin. The management protocols in such cases are discussed and relevant literature reviewed.

    Full Text Available Cerebral venous sinus thrombosis (CVST is a rarely encountered condition during pregnancy. A 21-year-old pregnant woman with labour pains was hospitalized in our clinic. Diagnosis of severe preeclampsia was made based on her clinical and laboratory findings. She suffered from convulsive episodes during postpartum period which lead to initiation of treatment for eclampsia. However neurological and radiological examinations were performed after emergence of additional neurological symptoms disclosed the diagnosis of CVST. In this paper, we aimed to present a case with CVST which diagnosis was confused with eclampsia and resulting in maternal mortality.

    Full Text Available Objectives: To study the clinical and neuroimaging correlation in patients with cerebral sinus venous thrombosis. Methods: Clinically suspected 50 patients of CSVT, were subjected to neuro imaging techniques, fulfilling the study criteria were recruited by simple random sampling and data collected was analyzed by correlational studies. Results: Of the 50 patients, 29 (58% were females and 21 (42% were males, and the mean age was 29.7 years, with maximum incidence of 87.5% in age group 20-40 years. Most common symptoms were headache 88%, seizures 66%, focal deficits 54%, altered sensorium 52% and mode of presentation was sub acute in 46% cases. Radiologically most common sinus involved was superior sagittal sinus 70%. 5 patients died during hospitalization. Out of the survived patients 35 patients (70% had complete recovery. Poor prognostic factors at the time of admission were stupor and coma and evidence of haemorrhagic infarction in primary CT scan. Conclusion: Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Overall prognosis was good, but small percentage of patients died. Management with heparin and oral anticoagulants is safe and effective.

    Full Text Available : The association of antiphospholipid antibodies with vascular thrombotic episodes is well established. In absence of other connective tissue disease such an association is very rare & known as the primary antiphospholipid antibody syndrome. Cerebral venous sinus thrombosis is associated with hypercoaguable states and a number of immune-mediated conditions. However the report of cerebral venous sinus thrombosis with antiphospholipid antibodies alone is limited. Here a case presenting with painful bilateral ophthalmoplegia with bilateral optic disc edema (due to raised intra cranial tension showing positive lupus anticoagulant in serum and right central venous sinus (transverse and sigmoid thrombosis on MRI and MR venogram is reported which showed clinical improvement with anticoagulant therapy

    Full Text Available Cerebral venous sinus thrombosis (CVT is a rare cerebrovascular disease with variable presentation. CVT rarely causes hydrocephalus. Communicating hydrocephalus due to CVT is extremely rare. We describe a patient of CVT presenting with chronic headache and communicating hydrocephalus. The patient was successfully treated with ventriculoperitoneal (VP shunt. A 40 year old man presented with moderate to severe headache since six months and progressive visual loss since two months. Head Computed tomogram showed mild hydrocephalus without obstruction. Lumbar puncture (LP demonstrated elevated pressure but was otherwise normal. Magnetic resonance venogram showed extensive CVT. Repeated CSF drainage and thecoperitoneal shunt did not relieve the severe headache hence a VP shunt was placed. Post shunt headache subsided with resolution of hydrocephalus. CVT can present as communicating hydrocephalus. Gradual reduction of intra-ventricular pressure by repeated LPs followed by VP shunt can safely treat hydrocephalus due to CVT.

    An otherwise serious and potentially fatal organic condition may present with a co-existing strong functional component. We encountered a female patient who presented with bouts of severe headache over the occipital region, associated with blurring of vision. Initially, non-contrast computed tomography (CT) scan (Brain) showed normal study, and she was deemed as having functional symptoms. Later, magnetic resonance imaging (MRI) (Brain) showed filling defect in right sigmoid sinus and magnetic resonance (MR) venography confirmed right sigmoid sinus thrombosis. On adequate anticoagulation, she did not improve and still had bouts of severe headache, although no longer associated with impaired vision. The treating neurophysician concluded that symptoms could no longer be accounted for by the organic condition. Overt and covert psychosocial stressors were found to be present in a detailed psychological exploration. Psychological intervention effectively controlled the headache. Thus, functional overlay can complicate the clinical picture in a severe organic condition and may require active psychiatric intervention over and above medical treatment.

    Full Text Available Globally Behcet%u2019s disease (BD is most frequently seen in Turkey and takes its name from the Turkish dermatologist Hulusi Behcet. Basic findings of the disease are the triad of genital ulcers, oral ulcers and uveitis. Neurological involvement in BD appears an average of 5 years after the beginning of disease, or the first appearance of the disease may be neurological findings. Sinus vein thrombosis (SVT is among neurological involvements observed in BD. However diagnosis of SVT is difficult and it is a situation that may cause disability or mortality. Our case was a 24-year old female patient with diagnosed SVT who had a diagnosis of BD from 5 years. In spite of the patient frequently applying to health services, SVT diagnosis was delayed until 15 days after the initial symptoms. BD can cause SVT and SVT may cause disability or mortality but SVT may be diagnosed late, just as in our case. Therefore we present this case to increase awareness of this disease.

    The present study aimed at investigating the prevalence of factor V Leiden G1691A, prothrombin G20210A, and MTHFR C677T in cerebral venous and sinus thrombosis (CVST) patients and their possible association with CVST in Western Iran. A total of 24 CVST patients with the mean age of 37.1 +/- 11.7 years and 100 sex- and age-matched healthy individuals from Kermanshah Province of Iran with ethnic background of Kurd were studied for factor V Leiden G1691A, prothrombin G20210A and MTHFR C677T by PCR-RFLP method using Mnl I, Hind III, and Hinf I restriction enzymes, respectively. Prevalence of factor V Leiden was 16.7% in patients and 2% in control group. A significant association was found between factor V Leiden mutation and CVST with odds ratio (OR) of 9.8 (95% confidence intervals [CI] 1.68-57.2, P = .01). No prothrombin G20210A was found among patients. In patients, MTHFR C677T tended to be higher (58.3%) compared to control (44%), OR of 1.8 (95% CI 0.73-4.5, P = .2). Our study for the first time has determined the prevalence of inherited thrombophilia in a homogenous ethnic group of CVST patients and suggests that factor V Leiden, and not the prothrombin gene mutation is a risk factor for CVST in Western Iran.

    The main objectives of the present study are to assess the incidence of cerebral venous thrombosis (CVT) presenting as isolated subarachnoid hemorrhage (SAH) and to determine the occurrence of cortical venous thrombosis (CoVT). Among 332 patients with CVT, investigated with the same CT and MR standardized protocol, 33 (10 %) presented with SAH, associated in 11 cases with hemorrhagic infarct or intracerebral hemorrhage. This study is based on 22 cases of CVT presenting as SAH in the absence of hemorrhagic brain lesion. Diagnosis of sinus thrombosis was established on T2* and magnetic resonance venography and that of CoVT on T2* sequence. Diagnostic of SAH was based on fluid-attenuated inversion recovery (FLAIR) sequence. CVT involved lateral sinus in 18 patients, superior sagittal sinus in 16, and straight sinus in 1. Cortical veins were involved in all patients, in continuity with dural sinus thrombosis when present. SAH was circumscribed to few sulci in all cases and mainly localized at the convexity (21 cases). CoVT implied different areas on the same side in four patients and was bilateral in seven. There was no perimesencephalic or basal cisterns hemorrhage. Cortical swelling was present in 12 cases, associated with localized edema. All patients except one had a favorable outcome. This report shows that the incidence of CVT presenting as isolated SAH is evaluated to 6.4 % and that SAH is, in all cases, in the vicinity of CoVT and when dural thrombosis is present in continuity with it.

    Full Text Available Background: The purpose of this study is to demonstrate the advantages of gradient echo (GRE sequences in the detection and characterization of cerebral venous sinus thrombosis compared to conventional magnetic resonance sequences.Methods: A total of 17 patients with cerebral venous thrombosis (CVT were evaluated using different magnetic resonance imaging (MRI sequences. The MRI sequences included T1-weighted spin echo (SE imaging, -weighted turbo SE (TSE, fluid attenuated inversion recovery (FLAIR, -weighted conventional GRE, and diffusion weighted imaging (DWI. MR venography (MRV images were obtained as the golden standard.Results: Venous sinus thrombosis was best detectable in -weighted conventional GRE sequences in all patients except in one case. Venous thrombosis was undetectable in DWI. -weighted GRE sequences were superior to -weighted TSE, T1-weighted SE, and FLAIR. Enhanced MRV was successful in displaying the location of thrombosis.Conclusion: -weighted conventional GRE sequences are probably the best method for the assessment of cerebral venous sinus thrombosis. The mentioned method is non-invasive; therefore, it can be employed in the clinical evaluation of cerebral venous sinus thrombosis.

    Clinical characteristics of systemic lupus erythematosus (SLE) patients complicated with cerebral venous sinus thrombosis (CVST) between 2000 and 2013 were analyzed through this retrospective, single-centre study. Of 4747 hospitalized SLE patients, 17 (0.36%, 12 females, average age 30) had CVST. Headache (88.2%) was the most common neurological symptom followed by nausea or vomiting (47.1%), conscious disturbance (41.2%), edema of eyelids or conjunctiva (35.3%), blurred vision or diplopia (35.3%), and seizure (35.3%). Increased intracranial pressure (ICP) occurred in 13 cases (76.5%). Magnetic resonance venography (MRV) detected thrombosis in the transverse (82.4%), sigmoid (52.9%), and sagittal (35.3%) sinuses, with frequent (70.6%) multiple sinus occlusions. Compared to SLE patients without CVST, SLE patients with CVST had a higher prevalence of thrombocytopenia and positive antiphospholipid antibodies and a higher SLE disease activity index (SLEDAI) score. 13 patients achieved improvement following glucocorticoids and immunosuppressants treatment, as well as anticoagulants, while 3 patients died at the hospital. CVST is relatively rare in SLE and tends to occur in active lupus patients. Intracranial hypertension is common but nonspecific clinical feature, so MRV evaluation is necessary to establish a diagnosis. Aggressive treatment for the rapid control of SLE activity combined with anticoagulants can improve the prognosis.

    Full Text Available Abstract Background To recognize ocular presentations in cranial venous sinus thrombosis (CVST which were easy to be misdiagnosis. Design Retrospective study. Methods Review clinical informations including general informations, general performances, and ocular presentations of 118 inpatients with CVST in the general hospital of chinese people's liberation army during 2005-2009. Main Outcome Measures The ocular symptoms as the initial onset presentations or simultaneous phenomenon among different onset type patients were analyzed. Results Of all the CVST patients, 21.2% (25/118 presented with ocular symptom as the initial presentation, 30.5% (36/118 presented with ocular symptom as well as the other symptoms, and 48.3% (57/118 presented with non-ocular symptoms as the initial onset. The CVST patients were divided into 3 groups according to the onset type. There was no marked statistical significance among groups. The most common major complaints were blurring and degeneration of acute vision, accounting for 85.9% (61/71 of all abnormal ocular chief complaints. The most common objective sign in eyes was papilloedema, accounting for 48.3% (57/118 in this group of CVST patients. About 22.4% (13/58 showed acute vision deterioration at 1-year follow-up, due to optic atrophy. Conclusions As ophthalmologists, we should master the onset characteristics and clinical manifestations of CVST. Early diagnosis and treatment is very important for the prevention of vision deterioration, especially for patients with ocular syndrome as the initial onset syndrome. For isolated agnogenic intracranial hypertension, we should consider the possibility of CVST.

    Reflux venous signal on the brain and neck time-of-flight magnetic resonance angiography (TOF MRA) is thought to be related to a compressed left brachiocephalic vein. This study is aimed to assess the prevalence of venous reflux flow in internal jugular vein (IJV), sigmoid sinus/transverse sinus (SS/TS), and inferior petrosal sinus (IPS) on the brain and neck TOF MRA and its pattern. From the radiology database, 3,475 patients (1,526 men, 1,949 women, age range 19-94, median age 62 years) with brain and neck standard 3D TOF MRA at 3 T and 1.5 T were identified. Rotational maximal intensity projection images of 3D TOF MRA were assessed for the presence of reflux flow in IJV, IPS, and SS/TS. Fifty-five patients (1.6 %) had reflux flow, all in the left side. It was more prevalent in females (n = 43/1,949, 2.2 %) than in males (n = 12/1,526, 0.8 %) (p = 0.001). The mean age of patients with reflux flow (66 years old) was older than those (60 years old) without reflux flow (p = 0.001). Three patients had arteriovenous shunt in the left arm for hemodialysis. Of the remaining 52 patients, reflux was seen on IJV in 35 patients (67.3 %). There were more patients with reflux flow seen on SS/TS (n = 34) than on IPS (n = 25). Venous reflux flow on TOF MRA is infrequently observed, and reflux pattern is variable. Because it is exclusively located in the left side, the reflux signal on TOF MRA could be an alarm for an undesirable candidate for a contrast injection on the left side for contrast-enhanced imaging study.

    Cerebral venous thrombosis (CVT) is a relatively rare but serious condition potentially reversible upon accurate diagnosis and adequate therapy. The peri-partum state and pregnancy are predisposing factors and TVC accounts for about 6% of maternal deaths. Its clinical symptoms depend on the the thrombus site and extension, and also on the existing collateral vessels network. We present the case of a 33 year-old woman, 13 weeks pregnant, that complained of headaches and whose cranial magnetic resonance imaging revealed a subtotal oclusión of the superior sagittal sinus. We discuss the imaging features of dural venous thrombosis in the acute phase.

    Full Text Available Cerebral venous sinus thrombosis (CVT can compromise dural sinus, cerebral veins or both. It is an uncommon condition and it is more prevalent in young women. Several prothrombotic states are the principal predisposing factors. Clinical spectrum of presentation is wide, so this entity requires a high suspect index for correct and prompt diagnosis. CVT may develop serious complications that can be life-threatening such as hemorrhagic venous infarctions, cerebral edema, and intracranial hypertension. This report describes the case of a woman who was in treatment for unspecific vaginal bleeding with oral contraceptives. Suddenly she deteriorated to coma with severe respiratory compromise. Neuroimaging showed thrombosis of multiple venous sinus. Physiological neuroprotection, osmotherapy, mechanical ventilation and anticoagulation therapy were the keystones of treatment. In a few months, the patient has recovered a good functional status, while maintaining a motor deficit on the right hand.

    Full Text Available Dural ectasia is one of the likely causes of incomplete or failed spinal anaesthesia. Its association with diseases like Marfans syndrome, neurofibromatosis, osteogenesis imperfecta, vertebral fracture, postopertative adhesions, trauma etc., is often overlooked as a reason for inadequate spinal anaesthesia. Greater than normal volume of cerebrospinal fluid in the lumber theca in dural ectasia is postulated to restrict the spread of intrathecally injected Local anaesthetic. Here, we report a case of failed spinal anaesthesia but successful epidural anaesthesia in later setting in a patient with dural ectasia.

We report the case of a CVT following lumbar puncture and intravenous glucocorticosteroid therapy in a female adolescent with a clinically isolated syndrome and risk factors for thrombosis. Conclusion. In adolescent patients with acute inflammatory disease undergoing lumbar puncture followed by intravenous high-dose glucocorticosteroid therapy, one should be aware of the elevated risk for thrombosis. A persistent headache with change in the headache pattern and loss of a postural component might be a sign for CVT, requiring emergency imaging of the brain.

    Full Text Available Septic cavernous sinus thrombosis (CST is an uncommon clinical syndrome. Although Staphylococcus aureus (S aureus is the most common bacterial pathogen causing CST, it is infrequent as a cause of meningitis. We report the first case of CST and meningitis from Bengaluru, Karnataka, caused by community-acquired epidemic methicillin resistant Staphylococcus aureus-15 (EMRSA-15, in a previously healthy individual without known risk factors; the patient recovered following treatment with vancomycin. The isolate was genotyped as belonging to staphylococcal cassette chromosome mec type IV and sequence type 22 and carried the panton-valentine leucocidin gene. It is the first Indian EMRSA-15 disease isolate from a case of meningitis. EMRSA-15 has been a major problem in hospitals in UK and it is a cause for great concern in Indian hospitals too.

    The topographical distribution of dural arteriovenous fistulas (DAVFs) was analyzed based on the embryological anatomy of the dural membrane. Sixty-six consecutive cases of intracranial and spinal DAVFs were analyzed based on the angiography, and each shunt point was identified according to the embryological bony structures. The area of dural membranes was categorized into three different groups: a ventral group located on the endochondral bone (VE group), a dorsal group located on the membranous bone (DM group) and a falcotentorial group (FT group) located in the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragm sellae. The FT group was designated when the dural membrane was formed only with the dura propria (meningeal layer of the dura mater) and not from the endosteal dura. Cavernous sinus, sigmoid sinus, and anterior condylar confluence was categorized to VE group, which had a female predominance, more benign clinical presentations, and a lower rate of cortical and spinal venous reflux. Transverse sinus, confluence, and superior sagittal sinus belonged to the DM group. Olfactory groove, falx, tent of the cerebellum, and nerve sleeve of spinal cord were categorized to the FT group, which presented later in life and which had a male predominance, more aggressive clinical presentations, and significant cortical and spinal venous reflux. The DAVFs was associated with the layers of the dural membrane characterized by the two different embryological bony structures. The FT group was formed only with the dura propria as an independent risk factor for aggressive clinical course and hemorrhage of DAVFs. PMID:27250699

    Full Text Available Abstract Introduction A 59-year-old Caucasian woman presented with an acute onset of alexia, noticed whilst driving. She described how while she could read car number plates, she had lost the ability to read and understand words on roadside advertisements and car window stickers. Case presentation Neurological examination was unremarkable apart from the inability to read full words or sentences. Imaging of the brain, initially computed tomography, followed by magnetic resonance venography, confirmed a diagnosis of sigmoid sinus thrombosis with associated venous infarction. The patient's past medical history revealed that she had suffered an ischemic stroke and following investigation for this, had undergone a nephrectomy for renal cell carcinoma. This was complicated by postoperative deep venous thrombosis. She had a persistent polycythaemia that was managed with venesection, and recently she had been diagnosed with Behçet's disease. Prior to this presentation, she had recently stopped her prophylactic antiplatelet medication as she was due to undergo a total knee replacement for osteoarthritis. She was managed with weight-adjusted, low molecular weight heparin followed by oral anticoagulation, and made a good recovery from her symptoms. Conclusion This case illustrates a classical neurological syndrome, highlights the importance of cerebral venous and sinus thrombosis as a cause of stroke, and the importance of remaining vigilant to a person's changing risk of venous thrombosis with evolving comorbidity.

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean{+-}SD; 19.72{+-}0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study. (orig.)

    Cerebral venous thrombosis (CVT) remains a diagnostic and therapeutic challenge for clinicians. Manifesting in a remarkably wide spectrum of symptoms and signs, CVT often presents in a misleading fashion-if unrecognized or misdiagnosed, it carries potentially fatal consequences. Visual loss is quite rare as the initial presentation of CVT and is typically a finding more frequent in chronic cases with associated papilledema on funduscopy Ferro, Lopes, Rosas and Fontes (Delay in Hospital Admission of Patients with Cerebral Vein and Dural Sinus Thrombosis. Cerebrovasc Dis 2005;19: :152-6). We report a rare case of acute cortical blindness as the initial presentation of CVT in an 18-year-old female patient and review the current literature.

    Full Text Available Intracranial dural arteriovenous fistulas (DAVFs are abnormal communications between arteries and veins or dural venous sinuses, which sit between the sheets of the dura. They represent 10% to 15% of intracranial vascular malformations. Clinical manifestations and prognosis depend on the pattern of venous drainage and location. The clinical presentation of DAVF may be mistaken for vascular or nonvascular brain pathologies. For that reason, within the differential diagnosis come a wide range of conditions, such as secondary headaches, encephalopathies, dementias including those with rapid progression, neurodegenerative diseases, inflammatory processes, or tumors typically at the orbital level or in the cavernous sinus. Diagnosis requires a high degree of suspicion because of the multiplicity of symptoms and presentations, making this pathology an entity that provides a major challenge for clinicians, yet early and multidisciplinary treatment of high-grade fistulas improve the possibility of avoiding poor or unfavorable outcomes for the patient.

    Arteriovenous fistulae of the cavernous sinus are rare and difficult to diagnose. They are classified into dural cavernous sinus fistulae or direct carotid-cavernous fistulae. Despite the similarity of symptoms between both types, a precise diagnosis is essential since the treatment is specific for each type of fistula. Imaging findings are remarkably similar in both dural cavernous sinus fistulae and carotid-cavernous fistulae, but it is possible to differentiate one type from the other. Amongst the available imaging methods (Doppler ultrasonography, computed tomography, magnetic resonance imaging and digital subtraction angiography), angiography is considered the gold standard for the diagnosis and classification of cavernous sinus arteriovenous fistulae. The present essay is aimed at didactically presenting the classification and imaging findings of cavernous sinus arteriovenous fistulae. (author)

    Full Text Available Background: Evidence is accumulating that venous thromboembolism is not limited to coagulation system and immune system seems to be involved in formation and resolution of thrombus. Some studies have demonstrated the role of inflammatory factors in deep venous thrombosis (DVT of limbs; however, there has not been such study in the patients with cerebral venous sinus thrombosis (CVST. The purpose of this study was to evaluate inflammatory cytokines including interleukin-6 (IL-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α in the patients with the history of CVST.Methods: In a cross-sectional study, 20 patients with the first episode of CVST and 20 age- and sex-matched healthy controls were included. The patients were seen only after anticoagulant treatment had been discontinued for at least 3 months. IL-6, IL-8, IL-10, TNF-α levels, and erythrocyte sedimentation rate (ESR were measured in two groups.Results: The median age of patients was 37.0 [interquartile range (IQR = 31.75-42.75] and in control group was 42.0 (IQR = 38.0-40.6 (P = 0.18. In patients group, 14 (70% were females and in control group, also, 14 (70% subjects were female (P = 0.01. It is significant that the level of IL-6 was significantly higher in the control group [patients: median: 9.75, IQR: 8.98-10.65; controls: median: 11.45, IQR: 10.28-13.10; P = 0.01]; however, the ESR level was higher in the patients. On the subject of IL-8, IL-10, and TNF-α, no significant difference was detected.Conclusion: We did not find higher concentrations of inflammatory ILs in the patients with the history of CVST that is contradictory with some findings in venous thrombosis of the extremities; however, the studies with larger sample size may be required.

    A 64-year-old woman underwent right suboccipital craniotomy to treat spontaneous cerebrospinal fluid (CSF) otorrhoea. Although the CSF leak was cured, the patient developed pulsatile tinnitus, ambulatory disturbance and progressive dementia. Four years after the surgery, she presented with generalised seizure. Cerebral angiography showed a dural arteriovenous fistula at the right transverse-sigmoid sinus, which was associated with sinus occlusion, retrograde blood flow in the sinus and diffuse intracranial cortical venous reflux. A combination of endovascular transarterial embolisation and transvenous embolisation with direct sinus puncture was performed. After the procedure, the patient's mental status and cognitive function improved significantly.

The aim of this study was to evaluate the frequency of common genetic thrombophilic factors in CVST patients. Forty consequently CVST patients from two University Hospital in Isfahan University of Medical Sciences aged more than 15 years from January 2009 to January 2011 were recruited. In parallel, 51 healthy subjects with the same age and race from similar population selected as controls. FV Leiden, FII GA20210, MTHFR C677T, and FV Cambridge gene mutations by polymerase chain reaction technique were evaluated in case and control groups. FV Leiden, FII GA20210, and FV Cambridge gene mutations had very low prevalence in both case (5%, 2%, 0%) and control (2.5%, 0%, 0%) and were not found any significant difference between groups. MTHFR C677T mutations was in 22 (55%) of patients in case group and 18 (35.5%) of control group (P = 0.09). This study showed that the prevalence of FV Leiden, FII GA20210, and FV Cambridge were low. Laboratory investigations of these mutations as a routine test for all patients with CVST may not be cost benefit.

    We describe the normal dural enhancement patterns of the sellar region and determine whether the duramater is affected by pituitary macroadenomas. Dural enhancement appeared to be usually abnormal in 20 patients with pituitary macroadenoma compared with 20 control patients, mainly at the planum sphenoidale and carotid sulcus. However dural changes are subtle and their recognition requires knowledge of the normal enhancement patterns. Dural changes, reported in a variety of inflammatory and infectious dural diseases and after surgery, are not specific and may be also seen in pituitary macroadenomas. (orig.)

    Cerebral venous thrombosis (CVT) is a rare thrombotic disorder involving the cerebral veins and dural sinuses. In contrast to more common sites of venous thromboembolism (VTE), such as the legs and lungs, CVT mainly affects young adults and children, and women are affected three times more often than men. Although presenting symptoms are variable, headache is usually the first symptom, often in combination with focal neurologic deficits and epileptic seizures. The primary therapy for CVT consists of heparin followed by oral anticoagulation for at least 3 to 6 months. The mortality in the acute phase is 5 to 10% and a substantial proportion of survivors suffer from long-term disabilities. A large number of risk factors have been linked to CVT, although the scientific evidence for an association varies considerably between risk factors. Some risk factors, such as hereditary thrombophilia, correspond with risk factors for more common sites of VTE, whereas others, such as head trauma, are specific to CVT. In most patients, at least one risk factor can be identified. In this review, we provide an overview of the risk factors for CVT.

    Cerebral venous thrombosis is a rare entity with widely variable clinical signs: thus, a high degree of suspicion is required for diagnosis. It affects the dural sinuses and may or may not invade cerebral veins. The diagnosis has usually been based on an angiographic study although, at the present time, new noninvasive imaging techniques, such as computed tomography, magnetic resonance and magnetic resonance angiography are being employed in a growing number of cases. Treatment should involve symptomatic and etiologic therapy. Although anti coagulation would appear to be a reasonable option in these patients, it remains controversial. As in other processes such as pulmonary embolism and coronary thrombosis, the introduction of novel and increasingly safe fibrinolytic drugs, together with technical innovations in the field of interventional neuroradiology, is changing the perspectives for the management of these patients. We present the case of a 43-year-old woman with right sinus thrombosis who was treated with local thrombolysis plus alteplase (tissue plasminogen activator). The authors describe the technique employed and review the literature. (Author) 16 refs.

    A minority of intracranial dural arteriovenous fistulas progress with time. We sought to determine features that predict progression and define outcomes of patients with progressive dural arteriovenous fistulas. We performed a retrospective imaging and clinical record review of patients with intracranial dural arteriovenous fistula evaluated at our hospital. Of 579 patients with intracranial dural arteriovenous fistulas, 545 had 1 fistula (mean age, 45 ± 23 years) and 34 (5.9%) had enlarging, de novo, multiple, or recurrent fistulas (mean age, 53 ± 20 years; P = .11). Among these 34 patients, 19 had progressive dural arteriovenous fistulas with de novo fistulas or fistula enlargement with time (mean age, 36 ± 25 years; progressive group) and 15 had multiple or recurrent but nonprogressive fistulas (mean age, 57 ± 13 years; P = .0059, nonprogressive group). Whereas all 6 children had fistula progression, only 13/28 adults (P = .020) progressed. Angioarchitectural correlates to chronically elevated intracranial venous pressures, including venous sinus dilation (41% versus 7%, P = .045) and pseudophlebitic cortical venous pattern (P = .048), were more common in patients with progressive disease than in those without progression. Patients with progressive disease received more treatments than those without progression (median, 5 versus 3; P = .0068), but as a group, they did not demonstrate worse clinical outcomes (median mRS, 1 and 1; P = .39). However, 3 young patients died from intracranial venous hypertension and intracranial hemorrhage related to progression of their fistulas despite extensive endovascular, surgical, and radiosurgical treatments. Few patients with dural arteriovenous fistulas follow an aggressive, progressive clinical course despite treatment. Younger age at initial presentation and angioarchitectural correlates to venous hypertension may help identify these patients prospectively. © 2015 by American Journal of Neuroradiology.

    We reviewed the anatomy and embryology of the bridging and emissary veins aiming to elucidate aspects related to the cranial dural arteriovenous fistulae. Data from relevant articles on the anatomy and embryology of the bridging and emissary veins were identified using one electronic database, supplemented by data from selected reference texts. Persisting fetal pial-arachnoidal veins correspond to the adult bridging veins. Relevant embryologic descriptions are based on the classic scheme of five divisions of the brain (telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon). Variation in their exact position and the number of bridging veins is the rule and certain locations, particularly that of the anterior cranial fossa and lower posterior cranial fossa are often neglected in prior descriptions. The distal segment of a bridging vein is part of the dural system and can be primarily involved in cranial dural arteriovenous lesions by constituting the actual site of the shunt. The veins in the lamina cribriformis exhibit a bridging-emissary vein pattern similar to the spinal configuration. The emissary veins connect the dural venous system with the extracranial venous system and are often involved in dural arteriovenous lesions. Cranial dural shunts may develop in three distinct areas of the cranial venous system: the dural sinuses and their interfaces with bridging veins and emissary veins. The exact site of the lesion may dictate the arterial feeders and original venous drainage pattern.

On the other hand as D-Dimer (DD test has been reported to be a sensitive test for the exclusion of venous thromboembolism, we sought whether it could be useful in the diagnosis of cerebral venous thrombosis. A prospective study of 104 consecutive patients with headache or unusual ischemic stroke (infarction in brain CT, but not compatible with any brunch of cerebral arteries, suggesting CVT was conducted between 2003 and 2005. D-Dimer test determined for all patients in the emergency ward before MRI or MRV was performed. Titers above 500 ng/ml were regarded as positive test. From a total 104 patients, 21 cases (20.2% were confirmed (by MRI and/or MRV to have CVT, 20/21 (95.7% of whom had positive DD test. In the remainder 83 (without CVT it was only positive in 16.8% (14/83, which was statistically meaningful (P < 0.001. Specificity, sensitivity, negative and positive predictive values of DD test were 83.1, 95.2, 98.6 and 58.8%, respectively, so application of this test would be useful in the diagnosis of CVT and values below 500 ng/ml make acute thrombosis unlikely.

    We present two patients with a dural arteriovenous fistula (dAVF) of the ophthalmic sheath who developed progressive exophthalmos, conjunctival chemosis, and visual loss. These symptoms mimic those of cavernous sinus dAVFs. Dural AVFs of the ophthalmic sheath are extremely rare and their clinical management is controversial. We successfully treated these two patients by transvenous coil embolization. Transvenous embolization appears to be a safe and effective method to treat dAVFs of the ophthalmic sheath.

    Data regarding cerebral venous thrombosis in North Africa are scarce. This study aims to identify the clinical features, risk factors, outcome, and prognosis of cerebral venous thrombosis in Tunisia. Data of 160 patients with radiologically confirmed cerebral venous thrombosis, hospitalized in Mongi Ben Hmida National Institute of Neurology (Tunis, Tunisia), were retrospectively collected and analyzed. The mean age was 37.3 years with a female predominance (83.1%). The mode of onset was subacute in most cases (56.2%). Headache was the most common symptom (71.3%), and focal neurologic symptoms were the main clinical presentation (41.8%). The most common sites of thrombosis were the superior sagittal sinus (65%) and the lateral sinus (60.6%). More than 1 sinus was involved in 114 (71.2%) patients. Parenchymal lesions observed in 85 (53.1%) patients did not correlate with cerebral venous thrombosis extent. Major risk factors were obstetric causes (pregnancy and puerperium) found in 46 (38.6% of women aged <50 years) patients, followed by anemia (28.1%) and congenital or acquired thrombophilia (16.2%). Mortality rate was of 6.6%. Good outcome at 6 months (modified Rankin Scale ≤2) was observed in 105 (87.5%)of 120 patients available for follow-up. Predictors of poor outcome were altered consciousness and elevated plasma C-reactive protein levels. Clinical and radiologic presentation of cerebral venous thrombosis in Tunisia was quite similar to other parts of the world with, however, a particularly high frequency of obstetric causes. Plasma C-reactive protein level should be considered as a prognostic factor in CVT.

    @@ Dural arteriovenous fistulae (DAVF) is a rare intracranial vascular disease. It is pathologically characterized by direct shunting of the intracranial artery and vein, which results in cerebral ischemia, intracranial hemorrhage, neural deficit and intracranial murmur. The etiological mechanism of DAVF is not well known, but most researchers think it is associated with congenital abnormal development, especially abnormal development of dural blood vessels at the stage of embryogenesis. Recently, some researchers have found that DAVF is also associated with some acquired factors. This article reports a case who developed DAVF within 2 years after debridement of frontal bone fragmentation, depressed fracture, left frontal lobe contusion and superior sagittal sinus injury due to forehead knife-cut injury. The pathogenic mechanism was explored through a review of the related literatures.

    Full Text Available Epithelioid angiomyolipoma (E-AML, accounting for 8% of renal angiomyolipoma, is usually associated with tuberous sclerosis (TS and demonstrates aggressive behavior. E-AML is macroscopically seen as a large infiltrative necrotic tumor with occasional extension into renal vein and/or inferior vena cava. However, without history of TS, renal sinus and venous invasion E-AML would be a challenging diagnosis, which may lead radiologists to misinterpret it as a renal cell carcinoma (RCC. In this case presentation, we aimed to report cross-sectional imaging findings of two cases diagnosed as E-AML and pathological correlation of these aforementioned masses mimicking RCC.

    ún cuando los síntomas son severos, la reversibilidad puede ser completa.Justification: The thrombotic occlusiom of the cerebral veins or dural sinuses is a less frequent cause of stroke than arterial thrombosis. However; the epidemiologic studies indicate that this entity is not as unusual as it has been thougth previously. Up to where we know, there is no study published in the national literature being this, in fact, the reason of the present work. Aim: To identify the demographic, clinical and diagnostic characteristics of patients that suffered dural sinuses thrombosis. To describe the therapeutic methods used and the evolution of these patients. Materials and methods: Clinical files of 11 diagnosed cases of dural sinues thrombosis in the Hospital Dr. Rafael Angel Calderon Guardia were revised, in the period between January of 1996 to January of 1999. The possible risk factors, clinical presentation, radiologic studies and treatment used were analyzed. Results: The average age was of 32,6 years. 18,2% were male, while 81,8% corresponded to women. The most frequent manifestations were: headache (100%, vomit (91%, focal deficit (82%, alteration of the mental status (73%, papilledema (54,5% seizures (54,5% and data of meningeal irritation (36,4%. The sing of the empty delta was documented in 27,3% of the tomographic studies. The superior sagittal sinus was the most frequently affected (91%. Anticoagulation with intravenous heparin was used in 54,5% of the cases. Conclusions: Although we are aware of the limitations of our report, our intention has been to cal the attention on a cerebral vscular disease that although it is not as frequent as arterial thrombosis, it should be taken into consideration because of its potential effects on the patient´s health. The appropriate knowledge of this condition is important, because even when the symptoms are severe, the reversiblity can be complete.

Clinical and laboratory research over the last 30 years has shown that use of smaller-gauge needles, particularly of the pencil-point design, are associated with a lower risk of PDPH than traditional cutting point needle tips (Quincke-point needle. A careful history can rule out other causes of headache. A postural component of headache is the sine qua non of PDPH. In high-risk patients < 50 years, post-partum, in the event a large-gauge needle puncture is initiated, an epidural blood patch should be performed within 24–48 hours of dural puncture. The optimum volume of blood has been shown to be 12–20 mL for adult patients. Complications caused by autologous epidural blood patching (AEBP are rare.Keywords: post-dural puncture headache, gauge, needles, cause, risk, incidence

  17. Acute Cavernous Sinus Syndrome from Metastasis of Lung Cancer to Sphenoid Bone

    2012-01-01

    Full Text Available Cavernous sinus syndrome is a rare entity in oncology reported only in occasional case reports. Optimal therapy is thus poorly defined with rapidly progressive disease dominating the picture. Management includes prompt diagnosis, attempts at stabilization of cranial nerve function, and aggressive control of central pain syndrome. Here, we report cavernous sinus syndrome secondary to the original squamous cell carcinoma of the lung. With common presenting causes of this syndrome being infection, thrombosis or tumor, it might seem that metastatic tumor would be expected in a patient with a cancer diagnosis. What was not so expected was the extremely rapid progression from mild headache and mild trigeminal neuralgia with negative-contrast head CT to a massive, destructive lesion involving several skull bones and skull base, only 3 weeks later. In addition, the patient was severely immunosuppressed at the completion of induction chemotherapy. Infectious processes, although unlikely, were considered, as aggressive cancer therapy (including high-dose steroids and radiation therapy had no impact on this disease. Despite accurate localization, the aggressive nature of this disease with massive bone destruction and dural thickening limited any chance of a durable control. We discuss the process of evaluation, diagnosis and treatment of symptoms and the importance of a team approach to best palliate these unfortunate patients.

    Objective: To study the association between the 'dural tail sign' and spinal meningiomas on MR imaging. Methods: Retrospective review of MR examinations of all pathologically proven spinal meningiomas from 1998 to 2005 was performed. Lesions were evaluated for size, signal intensity, enhancement pattern, and presence or absence of dural tail. The dural tail length and direction in reference to the meningioma were also evaluated. Results: Seven spinal meningiomas were identified in seven patients. One lesion was purely extradural, while the remaining were intradural extramedullary. Dural tail was present in four cases (57%) and its length ranged between 5 and 21 mm. The tail was seen cranial and caudal to the meningioma in three cases and only cranially in one. Coronal images were available in three cases and in two of these; the dural tail was clearly depicted. Conclusions: 'Dural tail sign' is as common in spinal meningiomas as in cranial meningiomas.

    BACKGROUND:Over the past twenty years, improvements in neuroimaging have greatly improved the ability to diagnose cerebral venous sinus thrombosis, as well as isolated cortical venous thrombosis. Neuroimaging allows for variations to be detected in the cortical vein and venous sinus. Diagnosis of thromboses in the venous system should not depend entirely on angiography of undeveloped veins or venous sinus. Currently, the combination of magnetic resonance imaging and magnetic resonance venography is the gold standard for diagnosing cerebral venous sinus thrombosis, rather than digital subtraction angiography. This article summarizes clinical manifestations, results from computed tomography and magnetic resonance imaging in two cases of isolated cortical venous thrombosis, analyzed relevant literature, and discussed the clinical and imaging characteristics of isolated cortical venous thromboses.

    Objective To discuss the possible cause, clinical symptoms, radiologic characteristics, diagnosis and our treatment strategies of cerebral venous sinus thrombosis (SCVT) in pregnancy. Methods We presented 12 cases of pregnancy with emergent SCVT admitted between 1993 and 2013 in the Department of Neurology, Peking Union Medical College (PUMC) hospital. The average age was (26±5) (19~34). Computed tomography (CT)/magnetic resonance imaging (MRI) was performed in all 12 patients in acute/subacute period; magnetic resonance venography (MRV) in 9 and digital subtraction angiography (DSA) in 6. The possible pathogenesis, clinical symptoms, radiological ifndings, diagnosis and treatment strategies were discussed. Results Of the 12 pregnant or maternity patients with SCVT, 7 got the disease in early pregnancy, 1 in late pregnancy, 4 within 2 weeks after delivery, 1 after abortion. The accompanied diseases were:one with protein S deficiency, one with hyperhomocystinemia, one with idiopathic thrombocytopenia purpura, one with infection, one with anemia. Clinical onset was acute or subacute. Twelve patients had headache, 5 had epilepsy, 5 had focal neurological signs (including weakness, Babinski signs, numbness, ataxia, peripheral facial paralysis), 1 had visual loss, 4 had disturbance of consciousness. All 12 patients had MRI during acute or subacute period, 9 had abnormal parenchymal signals--7 had infarction or hemorrhagic infarction, 1 had cerebral hemorrhage, and 1 had cerebral edema. Transverse sinus and sigmoid sinus were involved in 9 cases, superior sagittal sinus in 8, straight sinus and inferior sagittal sinus in 2, jugular vein in 2. Treatment:pregnancy was timely terminated in 6 pregnant patients; 1 patient whose family disagreed to terminate pregnancy aggravated and went back home. Ten patients accepted heparinized anti-coagulation as soon as possible, and all of them got better when they were discharged. Conclusion When pregnant women had acute

    It is important that each dural sinus can be recognized during brain surgery and that the venous route can be used for interventional procedures. In this study, the anatomical features and patterns of the confluence of the sinuses were analyzed. The technique of contrast-enhanced three-dimensional magnetic resonance venography was used in 549 patients. There were many anatomical variations in the confluence of the sinuses. Most cases had wide communication between the right and left transverse sinuses. Careful examination of the confluence of the sinuses is essential for the preoperative evaluation of posterior cranial fossa lesions and interventional procedures using the venous route. (orig.)

    Embolization therapy has been used as the initial treatment for spinal dural arteriovenous fistula (SDAVF) only for certain patients or in certain medical institutions due to its minimal invasiveness, but the recurrence of embolization remains a clinical challenge. The recurrent patient usually exhibits a gradual onset of symptoms and progressive deterioration of neurological function. Developing paraplegia several hours after embolization is commonly seen in patients with venous thrombosis-related complications, for which anticoagulation therapy is often administered. This article reports on a SDAVF patient who had weakness of both lower extremities before embolization and developed complete paraplegia several hours after embolization therapy, later confirmed by angiography as fistula recurrence. The symptoms were relieved gradually after second embolization. The pathophysiology of this patient is also discussed.

    @@ Pulsatile tinnitus is commonly encountered in approximately 10% of a given population.1 Since causes of the disease vary, selecting appropriate protocols of imaging strategies is quite challenging.2 Vascular anormalies or diseases including anormalies of the carotid arteries and jugular veins, intracranial arteriovenous malformation and dural arteriovenous fistula (DAVF) are major causative factors of the disease. Before imaging studies, history inquiry and physical examination are important for detect the possible causes of pulsatile tinnitus. Different imaging examinations are depended on histories and clinical signs of different patients.

    Objectives To explore the clinical manifestations, treatment and prognosis of a case of blindness caused by nephrotic syndrome with cerebral venous sinus thrombosis (CVST). Methods The clinical manifestations, diagnosis and treatment of a case of NS with CVST were analyzed. The latest domestic and foreign reseach progresses in treatment for CVST in children were reviewed. Results Epilepsy suddenly appeared with diplopia, binocular vision loss and blindness in anticoagulant therapy for the child with NS. Brain magnetic resonance venography (MRV) suggested CVST. MRV reexam-ined showed that the intracranial thrombosis was completely dissolved after urokinase thrombolysis for one month followed by ineffective heparin anticoagulation. At present, international standards of anticoagulant therapy have been adopted in the treatment for CVST patients. Coagulation function (e.g.APTT) and international standardization ratio were monitored in order to prevent bleeding. Conclusions It is better to perform neural imaging examination early in suspected CVST patients. Anti-coagulation and thrombolytic therapy should be given immediately once the risk of bleeding was excluded and used for 3-6 months.%目的:探讨肾病综合征(NS)合并颅内静脉窦血栓(CVST)致失明患儿的临床表现、治疗方案及其预后。方法分析1例NS合并CVST患儿的临床特点及诊治经过,并复习和总结国内外有关儿童CVST治疗相关研究的最新进展。结果患儿在NS标准化抗凝治疗过程中突然出现抽搐等癫发作症状,并有复视、双眼视力下降、失明,头颅磁共振及脑血管造影检查(MRV)示CVST形成,肝素化抗凝治疗效果不佳,后予尿激酶溶栓治疗1个月,复查MRV示颅内血栓已完全溶解。目前国际上针对CVST患儿已采取标准化抗凝治疗方案,并随时监测凝血功能如活化部分凝血活酶时间(APTT)、国际标准化比值(INR)等预防出血风险。结论

    Curative endovascular treatment of sphenoid wing dural arteriovenous fistula (dAVF) with pure cortical venous drainage is challenging because of its rarity, lack of accessible dural sinus for transvenous embolization (TVE), and proximity of skull base vital regions. Direct surgery to disconnect venous reflux has been favored. We report the curative endovascular treatment of two sphenoid wing dAVFs with pure cortical venous drainage. One patient revealed complete obliteration of dAVF by a single session of transarterial embolization (TAE). As part of strategic TAE for this complex dAVF, we used a novel approach to create a complete flow-arrest condition in which coils and an occlusion balloon were combined. A liquid agent was then injected across the pathological fistula and into the parent venous apparatus, thereby occluding the lesion. The other patient was treated with percutaneous TVE after TAE was unsuccessful. With a specific strategy and appropriate devices, the microcatheter was successfully introduced through sigmoid sinus, transverse sinus, superior sagittal sinus, and refluxing cortical vein by puncture of the jugular vein. Coils were deployed at the venous side of the fistula, resulting in successful obliteration of the dAVF. Sphenoid wing dAVF with pure cortical venous drainage could be curable by endovascular treatment with proper strategy and instruments when anatomical condition permits.

    Patients with dural arteriovenous fistulas (DAVFs) in the transverse-sigmoid sinus suffer from several symptoms: bruit, headache, visual impairment, and so on. But depression is rare in patients with DAVF. The authors reported a rare case presenting the improvement of depression after the treatment of a dural arteriovenous fistula in the left transverse-sigmoid sinus. A 46-year-old male had suffered from depression and was treated with antidepressants at a local hospital for four years. The patient was temporarily laid off due to his depression. Afterwards, he had Gerstmann's syndrome and came to our hospital. A DAVF in the left transverse-sigmoid sinus was demonstrated on the angiogram. The DAVF was successfully treated with endovascular surgery, coil embolization of the isolated diseased sinus through the mastoid emissary vein which was a draining vein from the fistula. After this treatment, his depression as well as Gerstmann's syndrome was improved and the quantity of the antidepressants decreased. The patient returned to work without any antidepressant two years after the treatment. DAVFs might be one of the causes of depression. It may be necessary to evaluate cerebral vessels in patients suffering from depression by using MRA or 3D-CTA even if there are not any abnormal findings on plain CT scans.

    Historically, humans have long sought to enhance their "athletic" performance to increase body weight, aggressiveness, mental concentration and physical strength, contextually reducing fatigue, pain, and improving recovery. Although regular training is the mainstay for achieving these targets, the ancillary use of ergogenic aids has become commonplace in all sports. The demarcation between ergogenic aids and doping substances or practices is continuously challenging and mostly based on perceptions regarding the corruption of the fairness of competition and the potential side effects or adverse events arising from the use of otherwise unnecessary ergogenic substances. A kaleidoscope of side effects has been associated with the use of doping agents, including behavioral, skeletal, endocrinologic, metabolic, hemodynamic, and cardiovascular imbalances. Among the various doping substances, the most striking association with thrombotic complications has been reported for androgenic anabolic steroids (i.e., cardiomyopathy, fatal and nonfatal arrhythmias, myocardial infarction [MI], intracardiac thrombosis, stroke, venous thromboembolism [VTE], limb arterial thrombosis, branch retinal vein occlusion, cerebral venous sinus thrombosis) and blood boosting (i.e., VTE and MI, especially for epoetin and analogs). The potential thrombotic complication arising from misuse of other doping agents such as the administration of cortisol, growth hormone, prolactin, cocaine, and platelet-derived preparations is instead speculative or anecdotal at best. The present article provides an overview on the epidemiological association as well as the underlying biochemical and biological mechanisms linking the practice of doping in sports with the development of thrombosis.

    Spinal dural arteriovenous fistulas (DAVFs) may arise at any level from the foramen magnum to the sacrum. Only a few case series of DAVFs at the foramen magnum have been reported, especially with patients presenting with subarachnoid hemorrhage (SAH). We performed a retrospective study of four such cases and summarize experiences in the diagnosis and surgical treatment of a DAVF at the foramen magnum. Four male patients, aged from 35 to 51 years, were admitted with severe headache. The cranial computerized tomography scans of all four patients showed SAH, with hemorrhage in the fourth ventricle with or without hemorrhage in the occipital horns of the lateral ventricles. Pre-operative digital subtraction cerebral angiography showed a DAVF at the foramen magnum draining to medullary veins and/or the straight sinus and the confluence of sinuses. Two DAVFs were fed by the vertebral artery, whilst the others were fed by dural branches of the occipital artery and/or the ascending pharyngeal artery. Three patients underwent direct microsurgical electrocoagulation and disconnection of the arteriovenous shunt via an enlargement of the foramen magnum and a hemilaminectomy at C1 by the far lateral suboccipital approach. Post-operative angiography confirmed complete obliteration of the fistula. Cerebral digital subtraction angiography is an effective and accurate method for examination of a DAVF at the foramen magnum. It can be treated effectively and with minimal surgical trauma by microsurgical electrocoagulation and disconnection of the shunt.

    Background Treatment of cavemous dural arteriovenous fistulas (DAVF) is usually made by a transartedal approach.However,in many complicated patients,treatments via transarterial approaches can not be achieved,and only an operation via a transvenous approach is feasible.We aimed to study the feasibility of transarterial embolJzation of cavernous dural arteriovenous fistulas with a combination detachable coils and Onyx to embolize a complicated cavemous DAVF via a transvenous approach.Methods From August 2006 to August 2007,six cases of complicated cavernous DAVF were embolized with a combination of detachable coils and Onyx via a transvenous approach.Three cases were male and the other three were female.Their ages ranged from 36 to 69 years old.The fistula was in the right lateral cavernous sinus in one case,in the left lateral cavernous sinus in another,and in the bilateral cavernous sinus in 4 cases.One fistula was fed by the right internal carotid artery and its meningohypophyseal trunk;one was fed by the branches of the left internal carotid artery and left extemal carotid artery;four were fed by the branches of the bilateral internal carotid artery and/or the bilateral external carotid artery.One case was drained via one lateral inferior petrosal sinus;three were drained via bilateral inferior petrosal sinuses;one was drained via one lateral ophthalmic and facial veins;one was drained via the infedor petrosal sinus and the ophthalmic and facial veins.Four were embolized via the inferior petrosal sinus,and two were embolized via the ophthalmic and facial veins.Results Among six cases of complicated cavernous DAVF,four were fully embolized with Onyx by a single operation,and two cases were fully embolized with Onyx following two operations.Transient headache was found after operation in all patients,but was cured after several days by the symptomatic treatments.In one case,the first operation via the inferior petrosal sinus was a failure;the feeding branches of

    Science.gov (United States)

    2008-01-01

    Introduction Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting less than 4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, additional malaise and fever. It affects 1−5% of the adult population each year in Europe. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with clinically diagnosed acute sinusitis, and with radiologically or bacteriologically confirmed acute sinusitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides, different doses [amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides], long-course regimens), antihistamines, cephalosporins or macrolides, decongestants (xylometazoline, phenylephrine, pseudoephedrine), doxycycline, saline nasal washes, steam inhalation, and topical corticosteroids (intra-nasal).

  16. Double spinal dural sheath: a cadaveric case report

    Directory of Open Access Journals (Sweden)

    Loughenbury P

    2010-03-01

    Full Text Available A previously unreported variation in the anatomy of the spinal dural sheath was observed during routine cadaveric dissection, consisting of a duplication of the dural layer, with layers adherent throughout their length. The double dural sheath completely enveloped the spinal cord and nerve roots, and extended from C2 to L5: both layers were of similar thickness to a single dural sheath. Duplication of the dura mater in the form of two complete dural sheaths has not been previously observed and/or reported in a cadaveric study. However, areas of localised duplication of the ventral aspect of the dural sheath have been observed during intra-operative dissection, particularly in association with idiopathic herniation of the spinal cord. Complete duplication of the spinal dura mater is of clinical interest in spinal surgery, particularly in relation to idiopathic spinal cord herniation.

    Full Text Available Objective and Importance. We present the rare occurrence of multiple dural-based tuberculomas mimicking leptomeningeal carcinomatosis in a young immunocompetent patient. Clinical Presentation. A 36-year-old man presented with a 2-month history of generalized epileptic activity and altered perception. Neurological examination was remarkable for bilateral Babinski's sign. Cranial magnetic resonance imaging (MRI revealed multiple dural-based enhancing lesions with cerebral edema. Intervention. A right frontal craniotomy was performed for diagnosis. Histological examination revealed multiple confluent necrotizing and nonnecrotizing granulomas with giant cells which was consistent with tuberculosis (TB, and the patient was placed on anti-TB therapy for 24 months. Conclusion. To the best of our knowledge isolated diffuse involvement of the dura mater by TB, mimicking leptomeningeal carcinomatosis, as the sole manifestation of disease has not been reported before. Since pachymeningeal TB is rarely suspected when atypical radiological appearance is combined with the absence of systemic disease, biopsy is inevitably required for diagnosis.

    Hirata, M; Kuroda, M; Koni, I

    1999-06-01

    A 46-year old man presented with an eight-day history of edema and was found to be nephrotic, with a plasma albumin level of 1.1 g/dl and urine protein excretion of 13.3 g/24 hrs. The level of plasma creatinine was normal at 1.0 mg/dl. A finding of renal biopsy was consistent with minimal change glomerulopathy. On the 6th hospital day, he suddenly developed a severe headache and was noted to have bilateral papilledema. Lumbar puncture revealed an opening pressure of 250 mm of water. Magnetic resonance venography showed an irregular flow in the superior sagittal sinus and right transverse sinus, a finding consistent with thrombus. The diagnosis of cerebral venous thrombosis was made, and the patient was given both Warfarin 2 mg/day and prednisolone 60 mg/day. A complete recovery from nephrotic syndrome was achieved within eight weeks. Nephrotic syndrome causes a hypercoagulable state, leading to both venous and arterial thrombosis. The most common clinical features are renal vein thrombosis, femoral vein thrombosis, and pulmonary embolism, however, cerebral venous sinus thrombosis is rare in patients with nephrotic syndrome. It is important to be aware of this complication, since prompt treatment with anticoagulation and control of nephrotic syndrome can lead to a successful outcome.

    the treatment of a dural arteriovenous fistula in the left transverse-sigmoid sinus. A 46-year-old male had suffered from depression and was treated with antidepressants at a local hospital for four years. The patient was temporarily laid off due to his depression. Afterwards, he had Gerstmann's syndrome and came to our hospital. A DAVF in the left transverse-sigmoid sinus was demonstrated on the angiogram. The DAVF was successfully treated with endovascular surgery, coil embolization of the isolated diseased sinus through the mastoid emissary vein which was a draining vein from the fistula. After this treatment, his depression as well as Gerstmann's syndrome was improved and the quantity of the antidepressants decreased. The patient returned to work without any antidepressant two years after the treatment. DAVFs might be one of the causes of depression. It may be necessary to evaluate cerebral vessels in patients suffering from depression by using MRA or 3D-CTA even if there are not any abnormal findings on plain CT scans.

    Spinal dural arteriovenous fistulas are rare spinal vascular malformations which can cause progressive paraparesis and paraplegia if not treated. As symptoms are unspecific diagnosis is often delayed and clinical outcome is dependent on early therapy. While magnetic resonance imaging (MRI) is the first choice imaging procedure, selective spinal digital subtraction angiography is necessary to analyze the angioarchitecture and to plan the treatment. This article provides an overview on the epidemiology, etiology, clinical aspects and imaging features as well as therapeutic aspects of spinal dural arteriovenous fistulas. Knowledge of spinal vascular anatomy is the basis for understanding spinal dural arteriovenous fistulas. (orig.)

    The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

    Objective To investigate the pathogenesis of intracranial dural arteriovenous fistula, with a focus on the role of angiogenic factors and chronic brain hypoperfusion in it. Methods 120 Sprague-Dawley rats were randomly divided into 4 groups: 1) Group A (n=25) , sham operation; 2) Group B (n = 25), thrombosis of the sagittal sinus; 3) Group C (n = 35), anastomosis of the right common carotid artery(CCA) to the external jugular vein(EJV) and occlusion of the proximate-cardiac end of the transverse sinus on the left; 4) Group D(n =35) , procedures done as Group C and thrombosis of the sagittal sinus was added. Mean arterial pressure, sinus pressure, blood flow of the brain were monitored during the operation and again tested 1, 2, 4, 12 weeks after operation in subgroups of animals, respectively. Histological examination was used to test the distribution and concentration of VEGF and MMP-9 in dura mater, arachnoid membrane, cortex and basal ganglia. Perfusion MRI of the brain was done to compare blood flow in different site of the brain. Results In group C and D, the mean blood pressure decreased soon after operation, and the sinus pressure elevated to (28.55±4. 92) mm Hg and kept stable at (22. 34 ±3.24) mm Hg 4 weeks later. The blood flow of the brain went down significantly after operation in group C and D, with markedly reduction in the right occipital lobe versus any of the other sites. Two weeks later the blood flow had returned to the normal level in the left side but remained abnormal in the right occipital lobe. Perfusion MRI found higher blood volume and longer mean time to enhance in the right occipital lobe, than in its contralateral side. Immunohistological stain of VEGF was positive in basal ganglia, right occipital lobe and arachnoid membrane one week after operation, but weakened in basal ganglia two weeks later. VEGF expression was weak in dura mater one week after operation, but became strongly positive from the 4th to 12th week after operation

    Renal vein thrombosis in adults is usually a complication of the nephrotic syndrome. Rarely, it has been reported in nonnephrotic women postpartum. The thrombosis may be a complication of the hypercoagulable state associated with both the nephrotic syndrome and pregnancy. Two postpartum patients with renal vein thrombosis and no prior history of renal disease are reported here. Neither patient had heavy proteinuria. In both cases, pyelonephritis was suspected clinically and the diagnosis of renal vein thrombosis was first suggested and confirmed by radiologic examination. Renal vein thrombosis should be considered in women presenting postpartum with flank pain.

We present a young man who developed cortical venous thrombosis after using androgens to increase muscle mass. He was hospitalised for parasthesia and dyspraxia in the left hand followed by a generalised tonic-clonic seizure. At admission, he was drowsy, not fully orientated, had sensory inattention, pronation drift and a positive extensor response, all on the left side. The patient had been using anabolic steroids (dainabol 20 mg/day) for the last month for bodybuilding. CT angiography showed a right cortical venous thrombosis. Anticoagulation therapy was started with intravenous heparin for 11 days and oral anticoagulation (warfarin) thereafter. A control CT angiography 4 months later showed resolution of the thrombosis. He recovered fully.

  15. New insights into the mechanisms of venous thrombosis.

    2012-07-01

    Venous thrombosis is a leading cause of morbidity and mortality in industrialized countries, especially in the elderly. Many risk factors have been identified for venous thrombosis that alter blood flow, activate the endothelium, and increase blood coagulation. However, the precise mechanisms that trigger clotting in large veins have not been fully elucidated. The most common site for initiation of the thrombus appears to be the valve pocket sinus, due to its tendency to become hypoxic. Activation of endothelial cells by hypoxia or possibly inflammatory stimuli would lead to surface expression of adhesion receptors that facilitate the binding of circulating leukocytes and microvesicles. Subsequent activation of the leukocytes induces expression of the potent procoagulant protein tissue factor that triggers thrombosis. Understanding the mechanisms of venous thrombosis may lead to the development of new treatments.

  16. Headache in the parturient: Pathophysiology and management of post-dural puncture headache

    Directory of Open Access Journals (Sweden)

    Gita Nath

    2011-01-01

    Full Text Available Headache in the postpartum period is common and multifactorial in origin. Apart from primary causes such as tension headaches and migraine, secondary headaches such as post-dural puncture headache (PDPH are increasingly common because of increasing use of regional anaesthesia and analgesia during childbirth. Preventive measures for PDPH include the use of smaller gauge pencil-point needles for spinal blocks; epidural needles of 18 G or less; using saline rather than air for epidural space identification and the use of ultrasound guidance, especially for difficult cases such as morbid obesity and spinal deformities. In case of accidental dural puncture (ADP, the choice is between inserting the catheter in an adjacent space or intrathecal catheterization. Current evidence seems to be in favour of inserting the epidural catheter into the subarachnoid space and using the intrathecal catheter for analgesia/anaesthesia after prominently labelling it as intrathecal, to prevent misuse. It should be removed after at least 24 hours and a 10 ml bolus of saline injected before removal of catheter may be helpful. Either way, having written protocols for the management of accidental dural puncture helps to reduce the incidence of PDPH. PDPH can be disabling in severity and can mar the whole experience of childbirth. In addition, severe untreated PDPH can cause complications such as nerve palsies, subdural hematoma and cerebral venous thrombosis. Conservative methods of treatment should be tried first such as adequate hydration, paracetamol, caffeine, sumatriptan or ACTH/hydrocortisone. Epidural blood patching is the most effective treatment for PDPH. It is more effective if done 24-48 hours after dural puncture. It is an invasive procedure with its own complications as well as a failure rate of up to 30%, so that a second or even third patch may be necessary. Both these facts should be intimated to the patient beforehand. Meticulous follow-up and evaluation

    Cryptococcal meningoencephalitis (CM) is a serious central nervous system infection caused by Cryptococcus neoformans, seen mostly in immunocompromised hosts and less in immunocompetent patients. The vast majority of cryptococcosis cases are seen as human immunodeficiency virus infections with advanced immunosuppression. Meningitis and meningoencephalitis are the most common clinical manifestations. Nevertheless, immunocompetent patients with CM are rarely reported. Cerebral venous sinus thrombosis is a rare complication of CM. Here, we report an immunocompetent patient with CM from a non-endemic area, who presented with an acute onset and atypical symptoms associated with cerebral venous thrombosis.

    Maxillary sinus hypoplasia is rare, with an estimated prevalence of 1-5%. Out of the CT scans performed in sinusal patients between March 1998 and June 1999, we report on 4 isolated maxillary sinus hypoplasia, 4 maxillary sinus hypoplasia associated to concha bullosa, and 10 isolated conchae bullosas. All cases were evaluated by nasosinusal endoscopy and CT scan. Size, location and uni/bilateral presentation of concha bullosa is correlated to maxillary sinus hypoplasia presence, specially with regards to uncinate process presence, medial or lateral retraction. The pathogenesis of maxillary sinus hypoplasia is reviewed, and its relation to concha bullosa, evaluating how this could explain some cases of the so called chronic maxillary sinus atelectasia, as an acquired and progressive variant of maxillary sinus hypoplasia in adults.

    Chronic sinusitis is a common disease that encompasses a number of syndromes that are characterized by sinonasal mucosal inflammation. Chronic sinusitis can be defined as two or more of the following symptoms lasting for more than 12 consecutive weeks: discolored rhinorrhea, postnasal drip, nasal obstruction, facial pressure or pain, or decreased sense of smell. Chronic sinusitis is further classified as chronic sinusitis with polyposis, chronic sinusitis without polyposis, or allergic fungal sinusitis using physical examination, and histologic and radiographic findings. Treatment methods for chronic sinusitis are based upon categorization of the disease and include oral and inhaled corticosteroids, nasal saline irrigations, and antibiotics in selected patients. Understanding the various forms of chronic sinusitis and managing and ruling out comorbidities are key to successful management of this common disorder.

    Patients with silent sinus syndrome typically present for investigation of facial asymmetry. Unilateral, spontaneous enophthalmos and hypoglobus are the prominent findings at examination. Imaging of the orbit and sinuses characteristically show unilateral maxillary sinus opacification and collapse with inferior bowing of the orbital floor. It has been suggested that SSS is due to hypoventilation of the maxillary sinus secondary to ostial obstruction and sinus atelectasis with chronic negative pressure within the sinus. Treatment involves functional endoscopic sinus surgery for reestablishing a functional drainage passage, and a reconstructive procedure of the floor of the orbit for repairing the hypoglobus and cosmetic deformity. Ophthalmologists, otorhinolaryngologists, and radiologists must be familiarized with this relatively newly reported disease.

    Occlusive clot formation in the veins causes venous thrombosis, the site most common in the deep veins of leg, called deep vein thrombosis. The clot can block blood flow and when it breaks off, called an embolism which in turn can damage the vital organs. Venous thrombosis occurs via three mechanisms ie, Virchow's triad. The mechanisms are decreased flow rate of blood, damage to the blood vessel wall and an increased tendency of the blood to clot. There are several factors which can increase a person's risk for deep vein thrombosis. The symptoms of deep vein thrombosis in the legs are pain, swelling and redness of the part. One variety of venous thrombosis is phlegmasia alba dolens where the leg becomes pale and cool. Investigations include Doppler ultrasound examination of the limb, D-dimer blood test, plethysmography of the legs, x-rays to show vein in the affected area (venography). Hospitalisation is necessary in some cases with some risk factors. The mainstream of treatment is with anticoagulants, mostly low molecular weight heparin for 6 months. Deep venous thrombosis is a rising problem. Early diagnosis and treatment is associated with a good prognosis.

    The discovery of an intracardial mass in patients presents a serious diagnostic dilemma. The differential diagnosis of this condition may seem abundant, but myxomas and intracardial thrombosis are the most frequent diagnoses. A connection between pregnancy and the presence of thrombosis has been documented frequently. Normal pregnancy leads to changes of the coagulative and fibrinolytic status toward a hypercoagulable condition which has its own physiological justification (the risk of blood loss decreases during labor). The case of a patient suffering from postpartal right ventricular thrombosis, which was successfully resolved by surgery as described in this contribution, demonstrates the value of a multidisciplinary approach.

    Due to progressive advances in surgical techniques, immunosuppressive therapies, and supportive care, outcomes from both solid organ transplantation and hematopoietic stem cell transplantation continue to improve. Thrombosis remains a challenging management issue in this context, with implications for both graft survival and long-term quality of life. Unfortunately, there remains a general paucity of pediatric-specific data regarding thrombosis incidence, risk stratification, and the safety or efficacy of preventative strategies with which to guide treatment algorithms. This review summarizes the available evidence and rationale underlying the spectrum of current practices aimed at preventing thrombosis in the transplant recipient, with a particular focus on risk factors, pathophysiology, and described antithrombotic regimens.

    A six-year-old Ragdoll cat underwent examination due to a six-month history of slowly progressive gait abnormalities. The cat presented with an ambulatory tetraparesis with a neurological examination indicating a C1-T2 myelopathy. Radiographs of the spine showed a radiopaque irregular line ventrally in the vertebral canal dorsal to vertebral bodies C3-C5. In this area, magnetic resonance imaging revealed an intradural extramedullary/extradural lesion compressing the spinal cord. The spinal cord was surgically decompressed. The cause of the spinal cord compression was dural ossification, a diagnosis confirmed by histopathological examination of the surgically dissected sample of dura mater. The cat gradually improved after the procedure and was ambulating better than prior to the surgery. The cat's locomotion later worsened again due to ossified plaques in the dura causing spinal cord compression on the same cervical area as before. Oral prednisolone treatment provided temporary remission. Ten months after surgery, the cat was euthanized due to severe worsening of gait abnormalities, non-ambulatory tetraparesis. Necropsy confirmed spinal cord compression and secondary degenerative changes in the spinal cord on cervical and lumbar areas caused by dural ossification. To our knowledge, this is the first report of spinal dural ossification in a cat. The reported cat showed neurological signs associated with these dural changes. Dural ossification should be considered in the differential diagnosis of compressive spinal cord disorders in cats.

    Highlights: • The conventional neuroimaging manifestations of dural arteriovenous fistulas are highly variable. • Identification of cortical venous reflux is important to prevent complications. • Tortuous and dilated vessels without a nidus are associated with cortical venous reflux. • Digital subtraction angiography remains the gold standard for DAVF diagnosis. - Abstract: Purpose: To compare the conventional CT and MR findings of DAVFs in relation to the venous drainage pattern on digital subtraction angiography (DSA). Materials and Methods: Cross-sectional imaging findings (CT and/or MR) in 92 patients were compared to the presence of cortical venous reflux (CVR) on DSA. Results: Imaging features significantly more prevalent in patients with CVR included: abnormally dilated and tortuous leptomeningeal vessels (92% vs. 4%, p < 0.001) or medullary vessels (69% vs. 0%, p < 0.001), venous ectasias (45% vs. 0%, p < 0.001) and focal vasogenic edema (38% vs. 0%, p < 0.001). The following findings trended towards association but did not reach the p value established following Bonferroni correction: dilated external carotid artery branches (71% vs. 38%, p = 0.005), cluster of vessels surrounding dural venous sinus (50% vs. 19%, p = 0.009), presence of hemorrhage (33 vs. 12%, p = 0.040), and parenchymal enhancement (21% vs. 0%, p = 0.030). Conclusion: In the appropriate clinical setting, recognition of ancillary signs presumably related to venous arterialization and congestion as well as arterial feeder hypertrophy should prompt DSA confirmation to identify DAVFs associated with CVR.

Iran J Child Neurol. Spring 2015;9(2:53-57.AbstractObjectiveHomocystinuria is an inborn error of amino acid metabolism caused by cystathionine beta-synthase deficiency that affects methionine metabolism. The clinical features are heterogeneous ranging from mental retardation, ectopia lentis, and osteoporosis to vascular events such as deep vein thrombosis,   sagital sinus thrombosis, and myocardial infarction. Cerebral sinovenous thrombosis (CVST is an unusual disorder in children and requires prompt and accurate management. Some causal factors for thedevelopment of CVST differ between children and adults. The majority of cases with CSVT are found to have an underlying cause for thrombosis like dehydration, infections, prothrombotic and hematologic disorders, malignancy and trauma.Although homocystinuria is usually associated with ischemic strokes, CVST as initial clinical presentation of homocystinuria is rare in children.In this article, we presented a 10-year old boy with seizure, hemiparesis, and ataxia due to CSVT caused by homocystinuria.

    To analyse the clinical, radiological and therapeutic variables of intracranial dural arteriovenous fistulae (DAVF) treated at our institution, and to assess the validity of the Borden and Cognard classifications and their correlation with the presenting symptoms. The DAVF identified were retrospectively analysed. They were classified according to their location, drainage pattern and the Borden and Cognard classifications. We recorded the different treatments, their complications and efficacy. There were 81DAVF identified between 1975 and 2012. The cavernous sinus (CS) location was the most frequent one. The Borden and Cognard classifications showed an interobserver Kappa index of 0.72 and 0.76 respectively. The odds ratio of aggressive presentation in the presence of cortical venous drainage (CVD) was 19.3 (2.8-132.4). No location, once adjusted by venous drainage pattern, showed significant association with an aggressive presentation. Endovascular transarterial treatment of cavernous sinus DAVF achieved symptomatic improvement of 78%, with a complication rate of 5%. The DAVF of non-CS locations, with CVD, treated surgically were angiographically shown cured in 100% of the cases, with no treatment-related complications. The presence of CVD was significantly associated with aggressive presentations. The Borden and Cognard classifications showed little interobserver variability. Endovascular treatment for CS DAVF is safe and relatively effective. Surgical treatment of non-CS DAVF with CVD is safe, effective and the first choice treatment in our environment.

    Osteomas of the cranial sinuses are rare, benign bony tumors that can be complicated by the formation of an intracranial pneumatocele. If not treated promptly, a pneumatocele can lead to abscess formation, meningitis, or ventriculitis. In the present case, an intracerebral pneumatocele was formed when an 18 cm(3) osteoma breached the posterior wall of the frontal sinus creating a one-way valve through which air could enter the intracranial cavity. The patient presented after forceful sneezing with nonspecific symptoms of headache, nausea, and vomiting. CT demonstrated a frontal collection of loculated air with mass effect within the left cerebral hemisphere. A partly mineralized mass occupied the left superior nasal ethmoid sinus and left frontal sinus. Of interest pathologically in this case, the tumor had a substantial osteoblastoma-like component. Surgical repair involved frontal craniotomy to remove the osteoma and debride frontal sinus mucosa, plugging the frontal nasal ducts and sinus with fat and bone wax, and dural restoration using an underwater closed drainage system to vent intracranial air and stabilize the patient.

    Full Text Available Portal vein thrombosis (PVT is the blockage or narrowing of the portal vein by a thrombus. It is relatively rare and has been linked with the presence of an underlying liver disease or prothrombotic disorders. We present a case of a young male who presented with vague abdominal symptoms for approximately one week. Imaging revealed the presence of multiple nonocclusive thrombi involving the right portal vein, the splenic vein, and the left renal vein, as well as complete occlusion of the left portal vein and the superior mesenteric vein. We discuss pathogenesis, clinical presentation, and management of both acute and chronic thrombosis. The presence of PVT should be considered as a clue for prothrombotic disorders, liver disease, and other local and general factors that must be carefully investigated. It is hoped that this case report will help increase awareness of the complexity associated with portal vein thrombosis among the medical community.

    Venous thromboembolic disease contributes to morbidity and mortality in certain groups of hospitalized patients, particularly those who have undergone surgery. Although principles of treatment have changed relatively little during the past 20 years, significant advances have been made in the diagnosis of deep vein thrombosis (DVT). Venography, once the only reliable diagnostic technique, has been largely replaced by noninvasive tests: impedance plethysmography, venous Doppler, /sup 125/I-radiofibrinogen-uptake test, and phleborheography. Virchow's triad of stasis, vessel injury, and hypercoagulability remains a valid explanation of the pathogenesis of thrombus formation, but laboratory and clinical data have refined our knowledge of how these factors interact to result in clinically significant disease. Knowledge of the natural history of venous thrombosis, plus heightened awareness of the long-term morbidity and expense associated with the postphlebitic syndrome, have led to increased interest in preventing DVT. Clinically and economically, venous thrombosis is best managed by prevention. 61 references.

  15. Thyroid carcinoma presenting as a dural metastasis mimicking a meningioma: A case report

    2011-01-01

    Full Text Available Context: Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. Case Report: We report a case of a 41-year old man presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect. After magnetic resonance imaging (MRI a suspect diagnosis of meningioma was made. The patient underwent surgery where a soft mass with transverse sinus invasion was encountered; the tumour was successfully resected employing microsurgical techniques. Histological examination revealed a thyroid follicular neoplasm with positive staining for follicular carcinoma in immunohistochemical analysis. Postoperatively levels of thyroid hormones were normal. Treatment was planned for the thyroid gland, patient receiving 6 courses of chemotherapy including paclitaxel. Conclusions: The present case emphasizes that although they are uncommon, dural metastasis can be mistaken for meningiomas. The definitive diagnosis of a meningioma should be established only after the histopathological analysis. Thyroid follicular carcinoma should be included in the differential diagnosis in cases of extrinsic tumoral lesions.

    The monthly incidence of deep vein thrombosis during pregnancy varies from 0.1 to 0.8 per 1000 pregnancies, depending on the study. These figures are undoubtedly an underestimation because they were determined from clinical events with no estimation of asymptomatic forms which, in general, increase the prevalence about 3-fold. Although the absolute figures are reliable, the consequences in terms of maternal mortality and post-phlebitis sequelae warrant the careful attention paid to this condition. Moreover, it should be recalled that the prevalence of superficial venous thrombosis is similar and may be associated with a risk of pulmonary embolism.

    BACKGROUND: Presently, over 40 kinds of dural grafts have been successively used in clinic. Among them, lyophilized human dura mater with good histocompatibility and less complications is applied most widely. But there are a few reports on cases of infected spongiform encephalopathy following application of lyodura. More ideal repair materials deserve to be further investigated.OBJECTIVE: To investigate the efficiency and safety of biological dural graft made by meninges from porkers to repair meningeal injury.DESIGN: A self-control observation.SETTING: Wuhan General Hospital of Guangzhou Military Area Command of Chinese PLA.MATERIALS: Sixteen New Zealand Rabbits, of either gender, weighing from 2 to 3 kg, of clean grade Ⅱ,with the age of 0.5 - 1 year, were involved in this experiment. The involved rabbits were provided by the Animal Experimental Center of the First Military Medical University of Chinese PLA. Biological surgical patch (dural graft) was developed by Guangdong Guanhao Biotechnological Co.,Ltd. It was processed by using meninges from porkers by tissue engineering technology.METHODS: This experiment was carried out in the Experimental Center of the 157 Hospital of Chinese PLA between December 2003 and June 2004. ① The experimental rabbits were anesthetized. Dura mater was exposed from two sides ofpostmedial line of coronal suture. A rectangular dura mater about 8 mm × 8mm in size was cut off. Then a biological surgical patch (dural graft) was sheared into insert with 8 mm diameter and sutured. The left dura mater was untouched and used as control. Scalp was sutured, and postoperative wound healing and recovery were observed. ②The anesthetized rabbits were sacrificed at postoperative 3, 14, 30 and 90 days, 4 rabbits once. The whole head was cut off, and its scalp was removed.Afterwards, the head was fixed by formalin. Tissues in operative site were obtained, performed routine paraffin embedding, sliced and conducted HE staining, finally, the

    We describe thrombosis, deep venous thrombosis (DVT) pulmonary embolism (PE; n = 9) and hip-knee osteonecrosis (n = 5) that developed after testosterone therapy (median 11 months) in 14 previously healthy patients (13 men and 1 woman; 13 Caucasian and 1 African American), with no antecedent thrombosis and previously undiagnosed thrombophilia-hypofibrinolysis. Of the 14 patients, 3 were found to be factor V Leiden heterozygotes, 3 had high factor VIII, 3 had plasminogen activator inhibitor 1 4G4G homozygosity, 2 had high factor XI, 2 had high homocysteine, 1 had low antithrombin III, 1 had the lupus anticoagulant, 1 had high anticardiolipin antibody Immunoglobulin G, and 1 had no clotting abnormalities. In 4 men with thrombophilia, DVT-PE recurred when testosterone was continued despite therapeutic international normalized ratio on warfarin. In 60 men on testosterone, 20 (33%) had high estradiol (E2 >42.6 pg/mL). When exogenous testosterone is aromatized to E2, and E2-induced thrombophilia is superimposed on thrombophilia-hypofibrinolysis, thrombosis occurs. The DVT-PE and osteonecrosis after starting testosterone are associated with previously undiagnosed thrombophilia-hypofibrinolysis. Thrombophilia should be ruled out before administration of exogenous testosterone.

    Superior mesenteric vein thrombosis was identified on computed tomographic scans in six patients. In each case, contrast-enhanced scans showed a high-density superior mesenteric vein wall surrounding a central filling defect. Four fo the six patients had isolated superior mesenteric vein thrombosis. A fifth patient had associated portal vein and splenic vein thrombosis, and the sixth patient had associated portal vein and inferior vena cava thrombosis. One of the six patients had acute ischemic bowel disease. The other five patients did not have acute ischemic bowel symptoms associated with their venous occlusion. This study defines the computed tomographic appearance of mesenteric vein thrombosis.

    Full Text Available This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar artery thrombosis has been treated by resection of the thrombosed ulnar artery segment. This report shows that a single blunt trauma can cause distal ulnar artery thrombosis in the hand and it can be treated merely by thrombosed segment resection in suitable cases.

    Pediatric cerebral sinovenous thrombosis (CSVT) is an important, though less common subtype of pediatric stroke. It has been linked to several risk factors, including cranial procedures, with few studies highlighting this relationship. The aim of this study was to characterize the diagnosis and treatment of CSVT after cranial surgery. An institutional pediatric stroke research database was used to identify all CSVT cases diagnosed within 30 days of cranial surgery from November 2004 to December 2014. Thirteen subjects were retrospectively analyzed for clinical presentation, surgical details, radiographic characteristics, laboratory study results, treatment, and outcome. Diagnostic testing and treatment adhered to a consensus-based institutional stroke protocol. Cranial vault reconstruction, subdural empyema evacuation, and tumor resection were each observed in three subjects. Eleven (85%) subjects had sinus exposure during surgery, and eight (73%) developed thrombus in a sinus within or adjacent to the operative field. Two (15%) had documented iatrogenic sinus injury. On post-operative testing, ten (77%) subjects had prothrombotic abnormalities. Seven (54%) were treated with anti-coagulation therapy (ACT) starting on a median of post-operative day (POD) 3 (IQR 1-3) for a median of 2.9 months (IQR 2.4-5.4). Median time to imaging evidence of partial or complete recanalization was 2.4 months (IQR 0.7-5.1). No symptomatic hemorrhagic complications were encountered. Pediatric CSVT may be encountered after cranial surgery, and decisions related to anti-coagulation are challenging. The risk of CSVT should be considered in pre-surgical planning and post-operative evaluation of cases with known risk factors. In our study, judicious use of ACT was safe in the post-operative period.

    2015-03-01

    Odontoma is a mixed odontogenic hamartoma involving both epithelial and mesenchymal tissues. If left untreated, it can lead to complications in certain conditions. Here is a rare presentation of an extensive complex odontoma in maxillary sinus pushing third molar near the orbital floor causing transient diplopia in upward gaze occasionally and chronic sinusitis. Although odontomata are not uncommon and are familiar to practitioners, but some aggressive cases may cause problematic sequelae. Even postoperative complications may result if oral surgeons are not aware of the potential pitfalls associated with the surgical removal of large maxillary antrum odontomata. This article reports a rare presentation which can be considered unique because when obstruction of sinus drainage is evident, serious complications such as orbital infections, epidural and subdural empyema, meningitis, cerebritis, cavernous sinus thrombosis, brain abscess and death can occur. It also addresses points and pitfalls concerning surgery to remove odontoma.

    We report magnetic resonance (MR), computed tomography (CT) and angiographic imaging of an unusual giant arachnoid granulation in the superior sagittal sinus in a man with headache and vertigo. Intrasinus pressure measurements revealed a significant pressure gradient across the lesion. MR imaging is useful to identify giant arachnoid granulation and dural sinus thrombosis, whereas dural sinus pressure measurement in certain cases of giant arachnoid granulations can be used to evaluate the lesion as the cause of the patient's symptoms.

    2015-08-01

    Full Text Available We report the case of a 25-year-old woman, who received epidural analgesia for labor pain and subsequently presented post-dural puncture headache. Conservative treatment was applied and epidural blood patch was performed. In the absence of clinical improvement and due to changes in the postural component of the headache, a brain imaging test was performed showing a bilateral subdural hematoma. The post-dural puncture headache is relatively common, but the lack of response to established medical treatment as well as the change in its characteristics and the presence of neurological deficit, should raise the suspicion of a subdural hematoma, which although is rare, can be lethal if not diagnosed and treated at the right time.

    We report on a 46-year-old patient in whom an intracranial dural arteriovenous (AV) fistula, supplied by a branch of the ascending pharyngeal artery, drained into spinal veins and produced rapidly progressive symptoms of myelopathy and brainstem dysfunction including respiratory insufficiency. Magnetic resonance imaging studies demonstrated brainstem oedema and dilated veins of the brainstem and spinal cord. Endovascular embolization of the fistula led to good neurological recovery, although the patient had been paraplegic for 24 h prior to embolization. This case demonstrates the MRI characteristics of an intracranial dural AV fistula with spinal drainage and illustrates the importance of early diagnosis and treatment. Even paraplegia may be reversible, if angiography is performed and the fistula treated before ischaemic and gliotic changes become irreversible. (orig.)

    Color Doppler US (CDUS) has been used for evaluation of cerebral venous sinuses in neonates. However, there is very limited information available regarding the appearance of superficial and deep normal cerebral venous sinuses using CDUS and the specificity of the technique to rule out disease. To determine the specificity, inter-modality and inter-reader agreement of color Doppler US (CDUS). To evaluate normal cerebral venous sinuses in neonates in comparison to MR venography (MRV). Newborns undergoing a clinically indicated brain MRI were prospectively evaluated. All underwent a dedicated CDUS of the cerebral venous sinuses within 10 h (mean, 3.5 h, range, and 2-7.6 h) of the MRI study using a standard protocol. Fifty consecutive neonates participated in the study (30 males [60%]; 25-41 weeks old; mean, 37 weeks). The mean time interval between the date of birth and the CDUS study was 19.1 days. No cases showed evidence of thrombosis. Overall agreement for US reading was 97% (range, 82-100%), for MRV reading, 99% (range, 96-100%) and for intermodality, 100% (range, 96-100%). Excellent US-MRI agreement was noted for superior sagittal sinus, cerebral veins, straight sinus, torcular Herophili, sigmoid sinus, superior jugular veins (94-98%) and transverse sinuses (82-86%). In 10 cases (20%), MRV showed flow gaps whereas normal flow was demonstrated with US. Visualization of the inferior sagittal sinus was limited with both imaging techniques. Excellent reading agreement was noted for US, MRV and intermodality. CDUS is highly specific to rule out cerebral venous thrombosis in neonates and holds potential for clinical application as part of clinical-laboratory-imaging algorithms of pre/post-test probabilities of disease.

    Dural granuloma is extremely rare. To our knowledge, there has no case reported solitary spinal dural syphilis granuloma worldwide so far. Here we report our findings in a 49-year-old woman, who presented with 10-year progressive left lower-limb numbness and two weeks of right lower-limb numbness. Magnetic resonance imaging (MRI) suggested a homogeneous enhanced spindle-shaped lesion, 2.9 × 1.5 cm in size, occupying the spinal intradural extramedullary space, at the level of Thoracic (T)-2/3, which mimicked the appearance of spinal meningioma. The Treponema pallidum particle agglutination (TPPA) test titer of 1:8, and the venereal diseases research laboratory of cerebral spinal fluid (VDRL-CSF) was reactive, so confirmed neurosyphilis was considered. After formal anti-syphilis treatment, posterior laminectomy surgery was performed, and the lesion was completely separated and extirpated. Final histopathologic diagnosis of the lesion was confirmed as chronic granulomatous inflammation, combined with the neurosyphilis history, spinal dural syphilis granuloma was finally diagnosed. Postoperatively, the patient recovered without any further treatment.

    Full Text Available We describe an effective surgical technique in primary repair of the spinal dura during minimally invasive spine surgery (MISS. Objective. Minimally invasive spine surgery includes the treatment of intradural lesions, and proper closure of the dura is necessary. However, primary dural closure can be difficult due to the restricted space of MIS retractors and the availability of appropriate surgical instrumentation. Methods. We describe the use of a needle already used in the pediatric neurosurgical arena that can facilitate easier and safer closure of spinal dura through MISS retractors in two illustrative intradural cases. Results and Discussion. The primary dural closure technique is described and patient demographics are included. The instruments specifically used for the intradural closure through MIS retractor systems include (1 4-0 Surgilon braided nylon (Covidien, Dublin, Ireland with a CV-20 taper 1/2 circle, 10 mm diameter needle; (2 Scanlan (Saint Paul, MN, USA dura closure set. Conclusion. Successful primary dural repair can be performed on primary and incidental durotomies during minimally invasive spinal surgery. We describe the novel use of a 10 mm diameter needle to help surgeons safely and efficiently close the dura with more ease than previously described.

    Neonatal renal vein thrombosis (RVT) continues to pose significant challenges for pediatric hematologists and nephrologists. The precise mechanism for the onset and propagation of renal thrombosis within the neonatal population is unclear, but there is suggestion that acquired and/or inherited thrombophilia traits may increase the risk for renal thromboembolic disease during the newborn period. This review summarizes the most recent studies of neonatal RVT, examining its most common features, the prevalence of acquired and inherited prothrombotic risk factors among these patients, and evaluates their short and long term renal and thrombotic outcomes as they may relate to these risk factors. Although there is some consensus regarding the management of neonatal RVT, the most recent antithrombotic therapy guidelines for the management of childhood thrombosis do not provide a risk-based algorithm for the acute management of RVT among newborns with hereditary prothrombotic disorders. Whereas neonatal RVT is not a condition associated with a high mortality rate, it is associated with significant morbidity due to renal impairment. Recent evidence to evaluate the effects of heparin-based anticoagulation and thrombolytic therapy on the long term renal function of these patients has yielded conflicting results. Long term cohort studies and randomized trials may be helpful to clarify the impact of acute versus prolonged antithrombotic therapy for reducing the morbidity that is associated with neonatal RVT.

    Sinusitis is commonly diagnosed with techniques such as endoscopy, ultrasound, X-ray, Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI). Out of these techniques, imaging techniques are less invasive while being able to show blockage of sinus cavities. This project attempts to develop a computerize system by developing algorithm for the segmentation of sinus images for the detection of sinusitis. The sinus images were firstly undergo noise removal process by median filtering followed by Contrast Limited Adapted Histogram Equalisation (CLAHE) for image enhancement. Multilevel thresholding algorithm were then applied to segment the enhanced images into meaningful regions for the detection and diagnosis of severity of sinusitis. The multilevel thresholding algorithms based on Otsu method were able to extract three distinct and important features namely bone region, hollow and mucous areas from the images. Simulations were performed on images of healthy sinuses and sinuses with sinusitis. The developed algorithms are found to be able to differentiate and evaluate healthy sinuses and sinuses with sinusitis effectively.

METHODS : Patients wit h paranasal sinus disease presenting to OPD at Government ENT Hospital, AMC, Visakhapatnam from January 2012 to June 2014 were screened for orbital manifestations. Out of these, thirteen patients with orbital disease were referred to GREH, AMC, Visakhapatn am and were thoroughly investigated and managed appropriately. RESULTS : Out of the 14 patients 4 were female and 10 were male. Age ranged from 19 years to 70 years. 5 had maxillary sinus disease (4 - carcinoma and 1 case of mucormycosis. Frontal sinus dis ease was seen in two patients, one fibrous dysplasia and one malignancy. Five patients had ethmoidal sinus disease of which three patients were found to have ethmoidal sinus tumour (Malignant melanoma, Squamous cell Carcinoma. More than two sinuses were i nvolved in 2 patients. CONCLUSIONS : Early screening of patients with sinus disease by an Ophthalmologist can help in preventing severe vision threatening orbital complications.

    The authors present their experience of managing an interesting case of a 65-year-old woman who presented to their clinic with 1-month history of persistent deep-seated headache. The patient sought medical advice in neurology and ophthalmology clinics before being referred to the ear, nose and throat clinic. CT imaging revealed isolated opacification and expansion of both sphenoid sinuses with bony continuity along the periphery of the sinuses features consistent with mucocele. MRI was needed to fully evaluate the extension of the lesion. The lesion was diagnosed as bilateral sphenoid sinuses mucoceles. Transnasal endoscopic drainage of the sphenoid mucoceles leads to gradual improvement of the symptoms. We discuss the clinical presentation, diagnosis and treatment of this case as well as a review of the literature. PMID:23093506

    A 70-year-old man presented with a rare case of paranasal osteoma with secondary mucocele extending intracranially, manifesting as a generalized convulsion. Computed tomography showed a large calcified tumor adjacent to the cystic mass in the left frontal lobe. He underwent left frontal craniotomy, and the cystic lesion was totally removed. Histological examination confirmed the diagnosis of osteoma and mucocele. The giant paranasal sinus osteoma prevented growth of the mucocele into orbital recess and extension into the orbital space and paranasal sinus. The mucocele disrupted the dura in the anterior cranial fossa, resulting in a giant cystic intracranial lesion. Frontal osteoplastic craniotomy was effective for exposing both lesions and plastic repair of the dural perforation to prevent cerebrospinal fluid leakage and secondary infection.

    2014-09-01

    Full Text Available Antiphospholipid syndrome (APS is a systemic autoimmune condition characterized by hypercoagulability, venous and/or arterial thromboses, and miscarriages. APS can be diagnosed according to specific criteria and is usually observed in young adults. We report a case of an elderly woman with past history of thrombosis and miscarriages who developed severe brain parenchymal hemorrhage and extensive thrombosis of the superior sagittal sinus due to APS. This case emphasizes that, although rare, APS may be diagnosed in elderly individuals and require effective anticoagulation.

    Three patients with mucormycosis of the paranasal sinuses were treated in the University ENT departments in Bochum and Essen in recent years. All patients were immunocompromised for different reasons and had reduced resistance against microorganism infection. They presented with symptoms of orbital complications of sinusitis. The further progress of these life-threatening fungal infections with a mortality rate between 35 and 70% depends on early and definitive diagnosis and radical surgical therapy to reduce the amount of infectious agent. The difficulties of early diagnosis by imaging, histology, microbiology, or molecular biology and postoperative therapeutic options especially with amphotericin B, liposomal amphotericin B, and posaconazole are illustrated and discussed.

    2014-04-01

    Trephination of the equine sinuses is a common surgical procedure in sedated standing horses. Standing sinus flap surgery has become increasingly popular in equine referral hospitals and offers several advantages over sinusotomy performed under general anesthesia, including reduced patient-associated risks and costs; less intraoperative hemorrhage, allowing better visualization of the operative site; and allows surgeons to take their time. Other minimally invasive surgical procedures include sinoscopic surgery, balloon sinuplasty, and transnasal laser sinonasal fenestration. Despite the procedure used, appropriate indications for surgery, good patient selection, and familiarity with regional anatomy and surgical techniques are imperative for good results.

    Acute fulminant invasive fungal sinusitis is most commonly found in immunocompromised patients with conditions such as diabetes mellitus, malignancies and acquired immune deficiency syndrome. The most common pathogens are Aspergillus and Mucoraceae and the sinus most frequently involved is the maxillary sinus. Fever, rhinorrhea, facial pain, headache, and diplopia are common presenting symptoms. Complications of this infection include intracranial and / or intraorbital spread of the infection; the prognosis is poor. Here, a rare case of acute fulminant invasive fungal sinusitis with cavernous sinus syndrome is reported.

    We screened previously undiagnosed thrombophilia (V Leiden-prothrombin mutations, Factors VIII and XI, homocysteine, and antiphospholipid antibody [APL] syndrome) in 15 men and 2 women with venous thromboembolism (VTE) or osteonecrosis 7 months (median) after starting testosterone therapy (TT), gel (30-50 mg/d), intramuscular (100-400 mg/wk), or human chorionic gonadotropin (HCG) (6000 IU/wk). Thrombophilia was studied in 2 healthy control groups without thrombosis (97 normal controls, 31 subjects on TT) and in a third control group (n = 22) with VTE, not on TT. Of the 17 cases, 76% had ≥1 thrombophilia vs 19% of 97 normal controls (P 150%) (24% vs 7%, P = 0.058), by high homocysteine (29% vs 5%, P = 0.007), and from both normal and TT controls for APL syndrome (18% vs 2%, P = 0.023, vs 0%, P = 0.04). Despite adequate anticoagulation with TT continued after the first deep venous thrombosis-pulmonary embolus (DVT-PE), 1 man sustained 3 DVT-PEs 5, 8, and 11 months later and a second man had 2 DVT-PEs 1 and 2 months later. Of the 10 cases with serum T measured on TT, 6 (60%) had supranormal T (>800 ng/dL) and of 9 with estradiol measured on TT, 7 (78%) had supranormal levels (>42.6 pg/mL). TT interacts with thrombophilia leading to thrombosis. TT continuation in thrombophilic men is contraindicated because of recurrent thrombi despite anticoagulation. Screening for thrombophilia before starting TT should identify subjects at high risk for VTE with an adverse the risk to benefit ratio for TT.

    2013-01-01

    Full Text Available Background: Mathematical approaches for biological events have gained significant importance in development of biomedical research. Deep vein thrombosis (DVT is caused by blood clot in veins deeply rooted in the body, resulting in loss of blood, pain, and numbness of the body part associated with that vein. This situation can get complicated and can be fatal, when the blood clot travels to other parts of the body which may result in pulmonary embolism (PE. PE causes approximately 300,000 deaths annually in the United States alone. Materials and Methods: We are trying to propose a computational approach for understanding venous thrombosis using the theory of fluid mechanics. In our study, we are trying to establish a computational model that mimics the venous blood flow containing unidirectional venous valves and will be depicting the blood flow in the veins. We analyzed the flow patterns in veins, which are included with lump like substances. This lump like substances can be clots, tissue debris, collagen or even cholesterol. Our study will facilitate better understanding of the biophysical process in case of thrombosis. Results: The predicted model analyzes the consequences that occur due to the clot formations in veins. Knowledge of Navier-Stokes equations in fluid dynamics along with the computational model of a complex biological system would help in diagnosis of the problem at much faster rate of time. Valves of the deep veins are damaged as a result of DVT, with no valves to prevent deep system reflux, the hydrostatic venous pressure in the lower extremity increases dramatically. Conclusion: Our model is used to determine the effects of an interrupted blood flow as a result of thrombin formation, which might result in disturbed systemic circulation. Our results indicated a positive inverse correlation exists between clots and the flow velocity. This would support medical practitioners to recommend faster curing measures.

  15. Fulminant Mucormycosis Involving Paranasal Sinuses: A Rare Case Report

    2014-01-01

    Full Text Available Mucormycosis is an opportunistic fulminant fungal infection, which has the ability to cause significant morbidity and frequently mortality in the susceptible patient. Common predisposing factors include diabetes mellitus and immunosuppression. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of the tissue. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. Here we describe a case of mucormycosis of maxillary antrum extending to ethmoidal and frontal sinus and also causing necrosis of left maxilla in an uncontrolled diabetic individual to emphasize early diagnosis and treatment of this fatal fungal infection.

    Dural defects are a common problem, and inadequate dural closure can lead to complications. Several types of dural substitute materials have recently been discarded or modified owing to poor biocompatibility or mechanical properties and adverse reactions. The small intestinal submucosa (SIS) is a promising material used in a variety of applications. Based on the limitations of previous studies, we conducted an animal study to evaluate the efficacy and safety of the SIS in preclinical trials. Twenty-four male beagle dogs were subjected to surgical resection to produce dural defects. SIS or autologous dural mater was patched on the dural defect. Gross and histological evaluations were carried out to evaluate the efficacy and safety of the therapy. Our findings demonstrated that the SIS, which stimulated connective and epithelial tissue responses for dural regeneration and functional recovery without immunological rejection, could provide prolonged defect repair and prevent complications. The mechanical properties of the SIS could be adjusted by application of multiple layers, and the biocompatibility of the material was appropriate. Thus, our data suggested that this material may represent an alternative option for clinical treatment of dural defects.

    Review costs for pediatric patients with complicated acute sinusitis. A retrospective case series of patients in a pediatric hospital was created to determine hospital costs using a standardized activity-based accounting system for inpatient treatment between November 2010 and December 2014. Children less than 18 years of age who were admitted for complicated acute sinusitis were included in the study. Demographics, length of stay, type of complication and cost of care were determined for these patients. The study included 64 patients with a mean age of 10 years. Orbital cellulitis (orbital/preseptal/postseptal cellulitis) accounted for 32.8% of patients, intracranial complications (epidural/subdural abscess, cavernous sinus thrombosis) for 29.7%, orbital abscesses (subperiosteal/intraorbital abscesses) for 25.0%, potts puffy tumor for 7.8%, and other (including facial abscess and dacryocystitis) for 4.7%. The average length of stay was 5.7 days. The mean cost per patient was $20,748. Inpatient floor costs (31%) and operating room costs (18%) were the two greatest expenditures. The major drivers in variation of cost between types of complications included pediatric intensive care unit stays and pharmacy costs. Although complicated acute sinusitis in the pediatric population is rare, this study demonstrates a significant financial impact on the health care system. Identifying ways to reduce unnecessary costs for these visits would improve the value of care for these patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Marfan syndrome is an autosomal dominant disorder of connective tissue caused by mutations in the gene encoding fibrillin-1 (FBN1), a matrix component of microfibrils. Dural ectasia, i.e. enlargement of the neural canal mainly located in the lower lumbar and sacral region, frequently occurs in Marfan patients. The aim of our study was to investigate the role of dural ectasia in raising the diagnosis of Marfan syndrome and its association with FBN1 mutations. We studied 40 unrelated patients suspected for MFS, who underwent magnetic resonance imaging searching for dural ectasia. In all of them FBN1 gene analysis was also performed. Thirty-seven patients resulted affected by Marfan syndrome according to the '96 Ghent criteria; in 30 of them the diagnosis was confirmed when revaluated by the recently revised criteria (2010). Thirty-six patients resulted positive for dural ectasia. The degree of dural ectasia was grade 1 in 19 patients, grade 2 in 11 patients, and grade 3 in 6 patients. In 7 (24%) patients, the presence of dural ectasia allowed to reach a positive score for systemic feature criterion. Twenty-four patients carried an FBN1 mutation, that were represented by 13 missense (54%), and 11 (46%) mutations generating a premature termination codon (PTC, frameshifts and stop codons). No mutation was detected in the remaining 16 (6 patients with MFS and 10 with related disorders according to revised Ghent criteria). The prevalence of severe (grade 2 and grade 3) involvement of dura mater was higher in patients harbouring premature termination codon (PTC) mutations than those carrying missense-mutations (8/11 vs 2/13, P = 0.0111). Our data emphasizes the importance of dural ectasia screening to reach the diagnosis of Marfan syndrome especially when it is uncertain and indicates an association between PTC mutations and severe dural ectasia in Marfan patients.

    Spinal dural arterio-venous fistula (DAVF) is rare and usually involves the thoracic segments. The classical presentation is a slowly progressive ataxia. Clinical presentation of intracranial DAVF depends on the site of the DAVF, as well as the vessels involved. Patients may present with pulsatile tinnitus, occipital bruit, headache, dementia, visual impairment as well as neurological deterioration distant from the DAVF as a result of venous hypertension and cortical haemorrhage. The authors present a rare case of progressive myelopathy secondary to an intracranial DAVF.

    The spinal dural arteriovenous fistula (SDAVF) is rare, presenting with progressive, insidious symptoms, and inducing spinal cord ischemia and myelopathy, resulting in severe neurological deficits. If physicians have accurate and enough information about vascular anatomy and hemodynamics, they achieve the good results though the surgery or endovascular embolization. However, when selective spinal angiography is unsuccessful due to neurological deficits, surgery and endovascular embolization might be failed because of inadequate information. We describe a patient with a history of vasospasm during spinal angiography, who was successfully treated by spinal stereotactic radiosurgery using Novalis system.

  7. Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

    This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    Chronic sinusitis develops when the ostiomeatal complex becomes stenosed by the swelling of the sinus mucosa. Previously, the Caldwell-Luc method was performed for the treatment of chronic sinusitis. But postoperative complications, such as discomfort of the buccal skin and recurrence of sinusitis, frequently occurred after the operation. Today, endoscopic sinus surgery (ESS) has become widely used for the treatment of chronic sinusitis. The features of ESS allow for the restoration of the physical function of the sinus membrane and preservation of the physiological environment of the sinus. Therefore, sinus augmentation surgery can be safely performed at an insufficient alveolar bone height below the maxillary sinus when sinusitis is eliminated by the ESS. This article documents a patient history involving chronic sinusitis that was treated by the ESS therapy before sinus augmentation surgery as a pretreatment for insertion of dental implants.

    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.

    Intracranial dural arteriovenous fistulas (dAVFs) with perimedullary drainage represent a rare subtype of intracranial dAVF. Patients usually experience slowly progressive ascending myelopathy and/or lower brainstem signs. We present a case of foramen magnum dural arteriovenous fistula with an atypical clinical presentation. The patient initially presented with a generalised tonic-clonic seizure and no signs of myelopathy, followed one month later by rapidly progressive tetraplegia and respiratory insufficiency. The venous drainage of the fistula was directed both to the left temporal lobe and to the perimedullary veins (type III + V), causing venous congestion and oedema in these areas and explaining this unusual combination of symptoms. Rotational angiography and overlays with magnetic resonance imaging volumes were helpful in delineating the complex anatomy of the fistula. After endovascular embolisation, there was complete remission of venous congestion on imaging and significant clinical improvement. To our knowledge, this is the first report of a craniocervical junction fistula presenting with epilepsy. PMID:26472637

    We assessed the morphological and radiological characteristics of ethmomaxillary sinus (EMS), which is an enlarged posterior ethmoidal air cell occupying the superior portion of the maxillary sinus while draining into superior meatus. This study is based on 1450 patients submitted to CT examination of the paranasal sinuses between 1998 and 2002. Sequential CT scans were obtained in the coronal plane in all the patients with 2.5- to 5-mm section thickness and were evaluated for EMS. The diagnosis of EMS was made when there was a posterior ethmoidal cell occupying the superior part of the maxillary sinus while draining to the superior meatus. When EMS was diagnosed, the morphology of the septum between the and maxillary sinus, and width of the superior meatus, were noted. The EMS was found in 10 of 1450 (0.7%) patients. The coexisting anatomic variations were concha bullosa (50%), upper concha pneumatization (20%), maxillary sinus hypoplasia (20%), uncinate bulla (10%), hypertrophied inferior concha (10%), paradoxic middle concha (10%), and septate maxillary sinus (10%). There was no relation between EMS and sinus disease. The EMS is a rare anatomic variation and does not appear to be associated with sinusitis. The EMS is not a well-studied anatomic variation, and the literature is lacking adequate information about this anatomic variation. This study performed in a large series of patients will possibly contribute to better understanding of this particular anomaly. (orig.)

  15. Thrombosis and the Pill.

    The results of 3 British and 1 American investigation of the risk of thromboembolism among women using oral contraceptives are reviewed. 1 British study conducted among general practitioners found the risk of developing superficial thrombophlebitis about 3 times greater among pill users. Neither of 2 other studies, in which hospital admissions and fatalities were analyzed, found any significant link between oral contraceptives and coronary thrombosis, but both indicated a 6 to 8-fold increase in risks of venous thromboembolism and of cerebral thrombosis. The findings of the American study were similar. None of the 4 studies discovered any evidence that the thromboembolic risk is greater early in the course of medication or, that it increases with duration of use. The American study obtained some evidence that sequential preparations might be more harmful than combined ones. The British Committee on Safety of Drugs has since determined, on the basis of analysis of routinely submitted reports of suspected adverse reactions, that the thromboembolic risk is higher with pills containing 75 mcg or more of estrogen than among those containing only 50 mcg. For the woman, who for any reason finds oral contraception to be the only satisfactory method of birth control, the risks may be considered acceptable provided medical supervision is adequate. Use of the pill entails other known major hazards (jaundice, hypertension) and knowledge of the longterm effects is very incomplete. Substantial evidence suggests that the estrogenic component of combined and sequential pills is responsible for the thromboembolic risks. The greater risks of pregnancy and menstrual disturbances accompanying progestogen-only oral contraceptives may limit their advantages.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    This study aimed to evaluate the feasibility of non-contrast-enhanced 4D magnetic resonance angiography (NCE 4D MRA) with signal targeting with alternative radiofrequency (STAR) spin labeling and variable flip angle (VFA) sampling in the assessment of dural arteriovenous fistula (DAVF) in the transverse sinus. Nine patients underwent NCE 4D MRA for the evaluation of DAVF in the transverse sinus at 3 T. One patient was examined twice, once before and once after the interventional treatment. All patients also underwent digital subtraction angiography (DSA) and/or contrast-enhanced magnetic resonance angiography (CEMRA). For the acquisition of NCE 4D MRA, a STAR spin tagging method was used, and a VFA sampling was applied in the data readout module instead of a constant flip angle. Two readers evaluated the NCE 4D MRA data for the diagnosis of DAVF and its type with consensus. The results were compared with those from DSA and/or CEMRA. All patients underwent NCE 4D MRA without any difficulty. Among seven patients with patent DAVFs, all cases showed an early visualization of the transverse sinus on NCE 4D MRA. Except for one case, the type of DAVF of NCE 4D MRA was agreed with that of reference standard study. Cortical venous reflux (CVR) was demonstrated in two cases out of three patients with CVR. NCE 4D MRA with STAR tagging and VFA sampling is technically and clinically feasible and represents a promising technique for assessment of DAVF in the transverse sinus. Further technical developments should aim at improvements of spatial and temporal coverage.

    Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal

    Full Text Available BACKGROUND AND PURPOSE: Dural ectasia is well recognized in Marfan syndrome (MFS as one of the major diagnostic criteria, but the exact prevalence of dural ectasia is still unknown in Loeys-Dietz syndrome (LDS, which is a recently discovered connective tissue disease. In this study, we evaluated the prevalence of dural ectasia in LDS according by using qualitative and quantitative methods and compared our findings with those for with MFS and normal controls. MATERIAL AND METHODS: We retrospectively studied 10 LDS (6 males, 4 females, mean age 36.3 years and 20 MFS cases (12 males, 8 females, mean age 37.1 years and 20 controls (12 males, 8 females, mean age 36.1 years both qualitatively and quantitatively using axial CT images and sagittal multi-planar reconstruction images of the lumbosacral region. For quantitative examination, we adopted two methods: method-1 (anteroposterior dural diameter of S1> L4 and method-2 (ratio of anteroposterior dural diameter/vertebral body diameter>cutoff values. The prevalence of dural ectasia among groups was compared by using Fisher's exact test and the Tukey-Kramer test. RESULTS: In LDS patients, the qualitative method showed 40% of dural ectasia, the quantitative method-1 50%, and the method-2 70%. In MFS patients, the corresponding prevalences were 50%, 75%, and 85%, and in controls, 0%, 0%, and 5%. Both LDS and MFS had a significantly wider dura than controls. CONCLUSIONS: While the prevalence of dural ectasia varied depending on differences in qualitative and quantitative methods, LDS as well as MFS, showed, regardless of method, a higher prevalence of dural ectasia than controls. This finding should help the differentiation of LDS from controls.

    OBJECT The microvascular anatomy of spinal dural arteriovenous fistulas (AVFs), especially the relationships of the vessels with the dura mater, has yet to be angiographically demonstrated in detail and proven histologically. METHODS From January 2012 through April 2014, a total of 7 patients with spinal dural AVFs in the thoracic region underwent open microsurgical obliteration at Tokyo Metropolitan Neurological Hospital. The microvascular anatomy of spinal dural AVFs was comprehensively assessed by using advanced microangiography, including 3D computer graphics and intraoperative indocyanine green video angiography, and by histological findings. RESULTS The 2 microangiography techniques revealed the spatial course and in vivo blood flow of the meningeal vessels and their relationships with the dura mater in sufficient detail. The meningeal branch of the intercostal artery split into multiple meningeal vessels on the outer dural surface adjacent to the root sleeve. After crossing the dura mater to the inner dural surface, these vessels gathered and joined a single intradural draining vessel. On the inner dural surface, the single draining vessel was fed by the surrounding multiple meningeal vessels, which appeared to be caput medusae. Histological findings revealed that the structure of the meningeal branch of the intercostal artery corresponded to that of a normal artery. The structure of intradural draining vessels corresponded to that of a vein modified by retrograde arterial inflow. On the inner dural surface, more than 1 meningeal artery gathered and joined with the proximal radiculomedullary vein. CONCLUSIONS Spinal dural AVFs are located on the inner dural surface, where multiple direct AV connections between more than 1 meningeal feeding artery and a single proximal radiculomedullary vein occur at the site where the vein connects to the dura mater.

    Maxillary sinusitis of odontogenic origin is a well-known condition in both the dental and otolaryngology communities. It occurs when the Schneiderian membrane is violated by conditions arising from dentoalveolar unit. This type of sinusitis differs in its pathophysiology, microbiology, diagnostics and management from sinusitis of other causes, therefore, failure to accurately identify a dental cause in these patients usually lead to persistent symptomatology and failure of medical and surgical therapies directed toward sinusitis. Unilateral recalcitrant disease associated with foul smelling drainage is a most common feature of odontogenic sinusitis. Also, high-resolution CT scans and cone-beam volumetric computed tomography can assist in identifying dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent functional endoscopic sinus surgery or Caldwell-Luc operation is required. The aim of this article is to give a review of the most common causes, symptoms, diagnostic and treatment methods of odontogenic maxillary sinusitis. Search on Cochrane Library, PubMed and Science Direct data bases by key words resulted in 35 articles which met our criteria. It can be concluded that the incidence of odontogenic sinusitis is likely underreported in the available literature.

    The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child. The child presented with an acute onset of significant visual impairment and headache. His vision gradually improved after trans-nasal sphenoidotomy and drainage of the sinus content with return of complete normal baseline vision after 2 months. (orig.)

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation.

    Full Text Available A trombose do seio dural é uma situação clínica rara, que resulta normalmente da complicação de processos infecciosos dos seios perinasais. Os sintomas e sinais são extremamente variados e inespecíficos sendo o diagnóstico feito através da ressonância magnética nuclear. Esse trabalho relata a ocorrência de trombose do seio dural em um paciente com idade pediátrica. Paciente com 10 anos de idade, sexo masculino, foi enviado ao serviço de urgência devido à diplopia e endotropia no olho esquerdo. No exame oftalmológico foi detectado papiledema bilateral, diplopia binocular e endotropia do olho esquerdo. Apresentava acuidade visual de 10/10 bilateralmente. Diante da suspeita de lesão ocupando espaço do sistema nervoso central, foi realizada ressonância magnética nuclear que confirmou o diagnóstico de TSD. Para avaliar a pressão intracraniana foi efetuada uma punção lombar com manometria, e esta demonstrou uma pressão intracraniana de 20mmHg (normal: <15mmHg. Perante isto a criança ficou internada para tratamento médico (enoxaparina de baixo peso molecular 1,5 mg/kg/dia subcutâneo (60 mg/dia, prednisolona 35 mg/dia oral e acetazolamida 250 mg/dia oral durante 10 dias. Após 1 mês de follow-up verificou-se agravamento oftalmológico. A realização de nova punção lombar apresentou uma pressão intracraniana de 40 mmHg que não cedia ao tratamento médico. Após discussão multidisciplinar do caso optou-se pela realização de derivação lombo-peritoneal. A necessidade de uma grande dose de suspeição clínica, tanto para o diagnóstico inicial quanto para a monitorização das complicações, tornam a abordagem da trombose do seio dural um processo singular.

    OBJECTIVE Preoperative magnetic resonance images (pMR) are typically coregistered to provide intraoperative navigation, the accuracy of which can be significantly compromised by brain deformation. In this study, the authors generated updated MR images (uMR) in the operating room (OR) to compensate for brain shift due to dural opening, and evaluated the accuracy and computational efficiency of the process. METHODS In 20 open cranial neurosurgical cases, a pair of intraoperative stereovision (iSV) images was acquired after dural opening to reconstruct a 3D profile of the exposed cortical surface. The iSV surface was registered with pMR to detect cortical displacements that were assimilated by a biomechanical model to estimate whole-brain nonrigid deformation and produce uMR in the OR. The uMR views were displayed on a commercial navigation system and compared side by side with the corresponding coregistered pMR. A tracked stylus was used to acquire coordinate locations of features on the cortical surface that served as independent positions for calculating target registration errors (TREs) for the coregistered uMR and pMR image volumes. RESULTS The uMR views were visually more accurate and well aligned with the iSV surface in terms of both geometry and texture compared with pMR where misalignment was evident. The average misfit between model estimates and measured displacements was 1.80 ± 0.35 mm, compared with the average initial misfit of 7.10 ± 2.78 mm between iSV and pMR, and the average TRE was 1.60 ± 0.43 mm across the 20 patients in the uMR image volume, compared with 7.31 ± 2.82 mm on average in the pMR cases. The iSV also proved to be accurate with an average error of 1.20 ± 0.37 mm. The overall computational time required to generate the uMR views was 7-8 minutes. CONCLUSIONS This study compensated for brain deformation caused by intraoperative dural opening using computational model-based assimilation of iSV cortical surface displacements. The u

    Pott's puffy tumor (PPT) and intracranial complications of sinusitis are considered rare in the post-antibiotic era. We present a series of pediatric patients who were diagnosed with these complications. The purpose of this study is to discuss the clinical presentations and imaging findings in order to increase awareness of pediatricians and radiologists. A computer search identified nine pediatric patients who were admitted to our hospital between October 2006 and July 2009. The patients' charts and imaging studies were reviewed. There were eight males (11-16 years old) and one female (9 years old). All patients presented with significant headache and fever. Only two patients had sinusitis symptoms. CT and MRI revealed sinusitis in seven patients. These patients were diagnosed with epidural abscess (six), subdural empyema (one), PPT (five), focal meningitis (six), and orbital cellulitis (four). Two patients did not have sinusitis on the day of admission, but were treated recently for sinusitis. These two patients presented with frontal epidural abscess, PPT, thrombosis of the superior sagittal sinus, and frontal bone osteomyelitis. All patients were treated with a multidisciplinary approach and had good outcome with no residual neurologic deficits. Complications of sinusitis are not rare in the studied population. The presentation may be misleading. Therefore, a high index of suspicion is needed, particularly in adolescent males who present with significant headache and fever. Evaluation with contrast-enhanced CT of the brain, sinuses, and orbits should be done first, followed by MRI examinations.

    Full Text Available Ameloblastomas are rare histologically benign, locally aggressive tumors arising from the oral ectoderm that occasionally reach a gigantic size. Giant ameloblastomas are a rarity these days with the advent of panoramic radiography in routine dental practice. Furthermore, the granular cell variant is an uncommon histological subtype of ameloblastoma where the central stellate reticulum like cells in tumor follicles is replaced by granular cells. Although granular cell ameloblastoma (GCA is considered to be a destructive tumor with a high recurrence rate, the significance of granular cells in predicting its biologic behavior is debatable. However, we present a rare case of giant GCA of remarkable histomorphology showing extensive craniofacial involvement and dural extension that rendered a good prognosis following treatment.

    Spinal dural arteriovenous fistula (SDAVF) is the most common spinal vascular malformation, however it is still rare and underdiagnosed. Magnetic resonance imaging findings such as spinal cord edema and dilated and tortuous perimedullary veins play a pivotal role in the confirmation of the diagnosis. However, spinal angiography remains the gold standard in the diagnosis of SDAVF. Classic angiographic findings of SDAVF are early filling of radicular veins, delayed venous return, and an extensive network of dilated perimedullary venous plexus. A series of angiograms of SDAVF at different locations along the spinal column, and mimics of serpentine perimedullary venous plexus on MR images, are demonstrated. Thorough knowledge of SDAVF aids correct diagnosis and prevents irreversible complications.

    A 72-year-old woman was admitted with rapidly progressive paraplegia and sphincter disturbance. T2-weighted images of the thoracic spine showed intramedullary high signal with flow voids suggesting dilated medullary veins. Conventional spinal angiography demonstrated a dural arteriovenous fistula draining into perimedullary veins. Perfusion-weighted MRI demonstrated a prolonged mean transit time and increased blood volume in the high-signal area. The loss of normal perfusion gradient and venous hypertension and were thought to produce these differences. The time-to-peak was almost identical in the high-signal and isointense areas, although the bolus of contrast medium arrived earlier in the former. Arteriovenous shunting was thought to cause faster inflow. These changes may have resulted in increased blood volume in the spinal cord. The high signal has been attributed to oedema due to venous congestion, but there has been no histological confirmation. Perfusion MRI in this case supports this hypothesis. (orig.)

    2008-01-01

    Vitamin K was discovered in the 1930s during cholesterol metabolism experiments in chickens. It is a fat-soluble vitamin which occurs naturally in plants as phylloquinone (vitamin K1) and is produced by gram-negative bacteria in the human gastrointestinal tract as menaquinone (vitamin K2). This vitamin was found to be essential for normal functioning of hemostasis. In addition, a number of clinical conditions in which vitamin K deficiency was found to be the underlying pathophysiologic problem were discovered. These conditions include hemorrhagic disease of the newborn, obstructive jaundice, and malabsorption syndromes. The importance of this vitamin has become more apparent with the discovery of the anticoagulant warfarin which is a vitamin K antagonist. There are millions of patients on this therapy for a variety of thrombogenic conditions such as atrial fibrillation, deep vein thrombosis, pulmonary embolism, and prosthetic cardiac valves. The wide use of this narrow therapeutic index drug has resulted in significant risk for major bleeding. Vitamin K serves as one of the major reversing agent for patients over-anticoagulated with warfarin. In the past few years, research has focused on new areas of vitamin K metabolism, which include bone and endovascular metabolism; cell growth, regulation, migration, and proliferation; cell survival, apoptosis, phagocytosis, and adhesion. These new areas of research highlight the significance of vitamin K but raise new clinical questions for patients who must be maintained on long-term warfarin therapy.

  12. Thrombosis in nephrotic syndrome.

    Nephrotic syndrome (NS) is characterized by heavy proteinuria, edema, hypoalbuminemia, and hyperlipidemia and the most frequent causes are glomerular diseases. An uncommon presentation is iatrogenic NS, an adverse effect of some drugs administration. In the clinical course of NS, a typical feature is dysregulated coagulation state, promoted by the breakdown of permselectivity barrier of the glomerular capillary wall, resulting in the leakage of high-molecular-mass proteins, at least the size of albumin. This hypercoagulable condition is supported by several factors, such as abnormalities in platelet activation and an imbalance between anticoagulation/antithrombosis and procoagulant/prothrombotic mechanisms. Thus, NS and the risk of developing thromboses are strictly related. Thrombotic events affect the venous system rather than arterial vessels with different features and frequencies. Deep venous system of the lower extremities and renal veins are the most frequent source of pulmonary embolism, the most dangerous NS complication. Prophylactic anticoagulation and thrombosis treatment are not clearly established because large randomized trials and guidelines are lacking. The management of NS and the decision of when and how to anticoagulate the patient represent a teamwork challenge for physicians.

    2013-10-01

    On the basis of strong research evidence, the pathogenesis of sinusitis involves 3 key factors: sinusostia obstruction, ciliary dysfunction, and thickening of sinus secretions. On the basis of studies of the microbiology of otitis media, H influenzae is playing an increasingly important role in the etiology of sinusitis, exceeding that of S pneumoniae in some areas, and b-lactamase production by H influenzae is increasing in respiratory isolates in the United States. On the basis of some research evidence and consensus,the presentation of acute bacterial sinusitis conforms to 1 of 3 predicable patterns; persistent, severe, and worsening symptoms. On the basis of some research evidence and consensus,the diagnosis of sinusitis should be made by applying strict clinical criteria. This approach will select children with upper respiratory infection symptoms who are most likely to benefit from an antibiotic. On the basis of some research evidence and consensus,imaging is not indicated routinely in the diagnosis of sinusitis. Computed tomography or magnetic resonance imaging provides useful information when complications of sinusitis are suspected. On the basis of some research evidence and consensus,amoxicillin-clavulanate should be considered asa first-line agent for the treatment of sinusitis.

    Acute invasive fungal sinusitis is the most aggressive form of fungal sinusitis and can be fatal, especially in patients who are immunosuppressed. Early diagnosis and intervention are crucial and potentially lifesaving, so primary care providers must maintain a high index of suspicion for this disease. Patients may need to be admitted to the hospital for IV antifungal therapy and surgical debridement.

    1999-07-01

    We present the radiological features of a 42-years-old man with long-standing inactive ankylosing spondylitis (AS), demonstrating that arachnoiditis is a cause of a cauda equina syndrome (CES) in this disease. CT showed a dorsal arachnoid diverticulum causing scalloped erosion of the laminae, and punctate and curvilinear dural calcification. MRI revealed adhesion and convergence of the cauda equina dorsally into the arachnoid pouch, causing the dural sca to appear empty canal. To the best of our knowledge, dural calcification on CT is a new finding in AS, which may be related to the CES. Our findings support the hyopthesis that chronic adhesive arachnoiditis with subsequent loss of meningeal elasticity may be the main cause of CES in AS. (orig.)

    Objective Many surgeons advocate for watertight dural reconstruction after posterior fossa surgery given the significant risk of cerebrospinal fluid (CSF) leak. Little evidence exists for posterior fossa dural reconstruction utilizing monolayer collagen matrix onlay graft in a non-watertight fashion. Our objective was to report the results of using collagen matrix in a non-watertight fashion for posterior fossa dural reconstruction. Methods We conducted a retrospective review of operations performed by the senior author from 2004–2011 identified collagen matrix (DuraGen) use in 84 posterior fossa operations. Wound complications such as CSF leak, infection, pseudomeningocele, and aseptic meningitis were noted. Fisher's exact test was performed to assess risk factor association with specific complications. Results Incisional CSF leak rate was 8.3% and non-incisional CSF leak rate was 3.6%. Incidence of aseptic meningitis was 7.1% and all cases resolved with steroids alone. Incidence of palpable and symptomatic pseudomeningocele in follow-up was 10.7% and 3.6% respectively. Postoperative infection rate was 4.8%. Previous surgery was associated with pseudomeningocele development (p<0.05). Conclusion When primary dural closure after posterior fossa surgery is undesirable or not feasible, non-watertight dural reconstruction with collagen matrix resulted in incisional CSF leak in 8.3%. Incidence of pseudomeningocele, aseptic meningitis, and wound infection were within acceptable range. Data from this study may be used to compare alternative methods of dural reconstruction in posterior fossa surgery. PMID:26885286

    A polyethylene glycol (PEG) hydrogel sealant recently has been approved as an adjunct to sutured dural closure in Japan. We treated consecutive six patients with PEG hydrogel sealant in posterior fossa operation. Three of six cases suffered delayed cerebrospinal fluid (CSF) leak after watertight dural closure with the PEG hydrogel sealant, although there was no leak case which was treated with fibrin glue, before 2 years until the adoption of the new material. These patients underwent posterior fossa craniotomy and discharged without remarkable CSF leak. The pseudomeningocele under the occipital wound caused the CSF leak occurr from 5th to 7th week postoperatively. All CSF leak cases needed surgical repair. At the repair, the PEG hydrogel was liquefied and almost absorbed. A fistula on the closure line and a dead space after the absorption of the PEG hydrogel was observed. When the absorbable PEG hydrogel sealant plugs in small gaps of sutured dura, its properties to prevent adhesion might suppress healing process of dural closure, so that CSF could leak through the gaps and collect as a pseudomeningocele in the dead space after absorption of the PEG hydrogel. In posterior fossa surgery a PEG hydrogel sealant should be applied when dural edges are closed tightly without any gaps.

    Limited alveolar bone height prevents the placement of dental implants. Sinus floor elevation is an internal augmentation of the maxillary sinus that allows implants to be placed. The principle of this surgical procedure is the preparation of a 'top hinge door', that is raised together with the Schneiderian membrane in the cranial direction. The space which created under this lid is filled with a bone transplant. Autogenous bone is the standard transplant material, despite the fact that a second surgery site is necessary. Under certain circumstances bone substitutes can be used, with a longer healing phase. If sufficient alveolar bone height is available to secure implant stability, simultaneous implantation and sinus floor elevation are possible. Considering the significant anatomical variation in the region of the maxillary sinus, a sound knowledge of the anatomy is of great importance.

    Acute paranasal sinus infection in children is often diagnosed clinically without the need for radiographic confirmation. Most cases have a favorable outcome following appropriate antibiotic therapy. A small percentage of cases where symptoms and signs are persistent or severe will require emergent imaging to rule out complications related to local spread of disease intraorbitally or intracranially. A strong index of suspicion is required in such cases, and cross-sectional imaging evaluation with CT and MRI should include axial and coronal images of the paranasal sinuses and, where appropriate, the orbits and brain (with attention to the cavernous sinus). There is no role for plain radiography in the evaluation of the complications of acute sinusitis in the pediatric patient. (orig.)

    Intracranial dural arteriovenous fistula (dAVF) usually results in various problems in the brain. But it can be presented as a myelopathy, which may make early diagnosis and management to be difficult. We recently experienced a case of cervical myelopathy caused by intracranial dAVF. A 60-year-old man presented with a 3-year history of gait disturbance due to a progressive weakness of both legs. Neurological examination revealed spastic paraparesis (grade IV) and Babinski sign on both sides. Magnetic resonance imaging showed serpentine vascular signal voids at C2-T1 on T2-weighted image with increased signal intensity and swelling of spinal cord at C1-C4. We performed a brain computed tomography angiography and found intracranial dAVF with multiple arteriovenous shunts. Venous drainages were noted at tentorial veins and cervical perimedullary veins. After Onyx embolization, the patient showed gradual improvement in motor power and gait disturbance. The venous drainage pattern is a well-known prognostic factor of dAVF. In our case, the intracranial dAVF drained to spinal perimedullary vein, which seemed to result in the ischemic myelopathy. Although it is rare condition, it sometimes can cause serious complications. Therefore, we should keep in mind the possibility of intracranial dAVF when a patient presents myelopathy. PMID:27437016

    To assess the feasibility of a selective flow-tracking cartographic procedure applied to four-dimensional (4D) flow imaging and to demonstrate its usefulness in the characterization of dural arteriovenous fistulas (DAVFs). Institutional review board approval was obtained, and all patients provided written informed consent. Eight patients (nine DAVFs) underwent 3.0-T magnetic resonance (MR) imaging and digital subtraction angiography (DSA). Imaging examinations were performed within 24 hours of each other. 4D flow MR imaging was performed by using a 4D radial phase-contrast vastly undersampled isotropic projection reconstruction pulse sequence with an isotropic spatial resolution of 0.86 mm (5 minutes 35 seconds). Two radiologists independently reviewed images from MR flow-tracking cartography and reported the location of arterial feeder vessels and the venous drainage type and classified DAVFs according to the risk of rupture (Cognard classification). These results were compared with those at DSA. Quadratic weighted κ statistics with their 95% confidence intervals (CIs) were used to test intermodality agreement in the identification of arterial feeder vessels, draining veins, and Cognard classification. Interreader agreement for shunt location on MR images was perfect (κ = 1), with good-to-excellent interreader agreement for arterial feeder vessel identification (κ = 0.97; 95% CI = 0.92, 1.0), and matched in all cases with shunt location defined at DSA. There was good-to-excellent agreement between MR cartography and DSA in the definition of the main feeding arteries (κ = 0.92; 95% CI = 0.83, 1.0), presence of retrograde flow in dural sinuses (κ = 1), presence of retrograde cortical venous drainage (κ = 1), presence of venous ectasia (κ = 1), and final Cognard classification of DAVFs (κ = 1, standard error = 0.35). MR selective flow-tracking cartography enabled the noninvasive characterization of cranial DAVFs. © RSNA, 2013.

    The aim of this review is to analyse the pathophysiology and complications of thrombosis in conjuction with ovarian hyperstimulation syndrome (OHSS) following ovulation induction and to suggest practical guidelines usefull for the prevention and treatment. Although the incidence of thrombosis varies from 0.2% among in vitro fertilization (IVF) cycles and up to 10% for severe cases of the syndrome, it represents the most dangerous complication of OHSS. Different changes in haemostatic markers have been found to create a state of hypercoagulability, but no single standard test is available to estimate the state of thrombosis. The role of markers for thrombophilia is controversial. Thromboses are mostly venous (67-75%) involving upper limbs and neck, then arterial (25-33%) which are mainly intracerebral. The predominant sites of venous thromboembolism in the upper part of the body may be explained by higher concentrations of estrogens drained through lymphatic ducts from ascites and by compression of rudimentary branchyal cysts. Once early diagnosis is established, it is crucial to use an anticoagulant treatment with heparin proceeded with thromboprophylaxis. However, identification of patients at risk and preventive measures of OHSS are the best means in reducing the risk of thrombosis after ovarian stimulation.

    A systematic study of thrombophilia markers in a large series of patients with cerebral venous thrombosis (CVT) from India is scarce. The present study was undertaken to know the prevalence of common hereditary thrombophilia in a large series of CVT patients from India. Six hundred and twelve (354 men, 219 women and 39 children) consecutive patients with CVT admitted to various hospitals in Mumbai between 2001 and 2010 were investigated for the common thrombophilia markers, that is, protein C (PC), protein S, antithrombin (AT), and factor V Leiden (FVL) mutation. The main presenting clinical manifestations included papilledema (62%), headache (62%), hemiparesis (48%), seizures (31%), and cranial nerve palsy (7%). All the patients were managed with heparin followed by warfarin during the succeeding 6 months. Superior sagittal sinus thrombosis was the commonest site (74%) followed by cortical venous thrombosis (15%). Associated clinical pathologies were dehydration, sepsis, pregnancy and puerperium, malaria, and tuberculosis; but in the majority of patients, there was no obvious cause. Eighteen percent of the patients had any of the thrombophilia markers studied; PC deficiency was the commonest thrombophilia marker followed by deficiency of protein S, FVL mutation and AT deficiency. The men below 45 years with PC deficiency (P=0.03) and women with protein S deficiency were significantly higher (P=0.04). In conclusion, CVT is not an uncommon cause of neurological deficit as was presented in earlier reports. Pregnancy and puerperium-related CVT was much less common. Thrombophilia markers accounted for approximately one-fifth of the patients. Death due to CVT has shown remarkable reduction (13%) because of early diagnosis and appropriate anticoagulation.

    Full Text Available To improve the efficacy and safety of dural repair in neurosurgical procedures, a new dural material derived from bacterial cellulose (BC was evaluated in a rabbit model with dural defects. We prepared artificial dura mater using bacterial cellulose which was incubated and fermented from Acetobacter xylinum. The dural defects of the rabbit model were repaired with BC membranes. All surgeries were performed under sodium pentobarbital anesthesia, and all efforts were made to minimize suffering. All animals were humanely euthanized by intravenous injection of phenobarbitone, at each time point, after the operation. Then, the histocompatibility and inflammatory effects of BC were examined by histological examination, real-time fluorescent quantitative polymerase chain reaction (PCR and Western Blot. BC membranes evenly covered the surface of brain without adhesion. There were seldom inflammatory cells surrounding the membrane during the early postoperative period. The expression of inflammatory cytokines IL-1β, IL-6 and TNF-α as well as iNOS and COX-2 were lower in the BC group compared to the control group at 7, 14 and 21 days after implantation. BC can repair dural defects in rabbit and has a decreased inflammatory response compared to traditional materials. However, the long-term effects need to be validated in larger animals.

    Objectives The roof of the porus trigeminus, composed of the posterior petroclinoid dural fold, is an important landmark to the skull base surgeon. Ossification of the posterior petroclinoid dural fold is an anatomical variation rarely mentioned in the literature. Such ossification results in the trigeminal nerve traversing a bony foramen as it enters Meckel cave. The authors performed this study to better elucidate this anatomical variation. Design Fifteen adult cadaveric head halves were subjected to dissection of the middle cranial fossa. Microdissection techniques were used to examine the posterior petroclinoid dural folds. Skull base osteology was also studied in 71 dry human skulls with attention paid to the attachment point of the posterior petroclinoid dural folds at the trigeminal protuberances. Setting Cadaver laboratory Main Outcome Measures Measurements were made using a microcaliper. Digital images were made of the dissections. Results Completely ossified posterior petroclinoid folds were present in 20% of the specimens. Of the 142 dry skull sides examined, 9% had large trigeminal protuberances. Conclusions Based on this study, the posterior petroclinoid dural fold may completely ossify in adults that may lead to narrowing of the porus trigeminus and potential compression of the trigeminal nerve at the entrance to Meckel cave.

    Full Text Available Aim: The watertight closure of the dura mater is fundamental to intracranial supratentorial procedures in neurosurgery. Controversies exist claiming the superiority of one closure technique over another. But is ′Water-tight′ dural closure really achievable ? An in vitro study system was developed to test the pressures at which dural incisions, closed with sutures, leaked. Materials and Methods: Bovine dura was secured to the lower end of an open ended calibrated plastic cylinder. Multiple interrupted stitches were applied over a two 2 cm length of the dura without any incision. Similarly a 2 cm incision was made and closed with interrupted and continuous stitches. Cylinder was filled with colored saline gradually. Height of the water column at which sutured dura leaked was recorded. The tests were conducted with the dura both in lax and tense conditions. Inlay closure technique was also tested on the same model using a dural substitute. Results: Even without an incision, needle puncture sites over a dura, leak, at a very low hydrostatic pressure (30 < mm of H2O, though a continuous interlocking suture performs slightly better than an interrupted suture technique. If the needle puncture sites are closed with glue, both the suture techniques can achieve a watertight closure against a hydrostatic pressure of 240 mm of H2O. Conclusion : In the experimental model described, ′Water-tight′ dural closure appears to be impossible with suture closure of a dural defect.

    Background Although there were several clinical and experimental studies discussing the pathogenesis of dural arteriovenous fistula (DAVF), the pathological process leading to intracranial DAVF so far remains unknown. In this study, we investigated the expression of vascular growth factors in order to elucidate the possible role of these factors for the development of DAVF and to study the biological activity of this uncommon lesion.Methods We examined the histological features, proliferative and angiogenic capacities of the tissue specimens obtained from 6 patients who underwent surgery at our institution. Immunohistochemical staining for vascular endothelial growth factor (VEGF), its receptors Flk-1 and Flt-1, ephrin-B2, MIB-1 and proliferating cell nuclear antigen (PCNA) was performed using standard immunohistochemical techniques. Results A positive immunostaining was found for all antibodies studied except MIB-1, whereas nuclear endothelial expression of PCNA was observed in only 3/6 cases. VEGF stained positive in all of the available specimens (6/6). Flk-1 showed a positive immunoreaction in only 2/6 cases and Flt-1 in 4/6 cases. Ephrin-B2 was expressed in the majority (5/6) of the cases.Conclusions These results support the hypothesis that DAVFs might be acquired dynamic vascular malformations with low biological activity. Vascular growth factors like VEGF and ephrin-B2 might play a pivotal role in the formation of DAVF.

    A 'dural tail' on Gd-DTPA-enhanced MRI has been often observed adjacent to meningiomas and considered to be useful in distinguishing meningioma of the cerebellopontine angle from acoustic neuroma. However, demonstration of a dural tail adjacent to an acoustic neuroma indicates that this sign is not specific. (orig.)

    2016-04-01

    Full Text Available We present quite a rare case of extracardiac unruptured right sinus of valsalva aneurysm (SVA complicated with atherothrombosis in a young adult man. A 35-year-old male with a giant unruptured SVA arising from the right coronary sinus (RCS with extracardiac protrusion was diagnosed by echocardiography. Contrast-enhanced computed tomography (CT revealed a huge calcified aneurysm with mural thrombi originating from the aortic root, and about 80% stenosis at the initial segment of the right coronary artery (RCA. Intraoperative exploration demonstrated a giant unruptured aneurysm arising from the RCS. Different from other SVAs reported before, this aneurismal wall appeared thick and atheromatous-like. In this aneurysm, there was a small localized intima tearing and mural thrombosis, and the orifice of the RCA was almost blocked. This patient underwent surgical patch repair to prevent aneurysm rupture and coronary artery bypass grafting for RCA revascularization. In conclusion, the pathological examination demonstrated marked foam cells, inflammatory cells, and thrombosis in the aneurismal wall. Learning points: • Echocardiographic characteristics of sinus of valsalva aneurysm (SVA. • Diagnostic evaluation of extracardiac unruptured SVA. • Pathology of rare SVA.

    The aim of this retrospective study was to evaluate the clinical outcome of patients with spinal dural arteriovenous fistulas (SDAVFs) that were treated with surgery, catheter embolization, or surgery after incomplete embolization. The study included 21 consecutive patients with SDAVFs of the thoracic, lumbar, or sacral spine who were treated in our institution from 1994 to 2007. Thirteen patients were treated with catheter embolization alone. Four patients underwent hemilaminectomy and intradural interruption of the fistula. Four patients were treated by endovascular techniques followed by surgery. The clinical outcome was assessed using the modified Aminoff-Logue scale (ALS) for myelopathy and the modified Rankin scale (MRS) for general quality of life. Patient age ranged from 44 to 77 years (mean 64.7 years). Surgical as well as endovascular treatment resulted in a significant improvement in ALS (-62.5% and -31.4%, respectively, p<0.05) and a tendency toward improved MRS (-50% and -32%, respectively) scores. Patients that underwent surgery after endovascular treatment due to incomplete occlusion of the fistula showed only a tendency for improvement in the ALS score (-16.7%), whereas the MRS score was not affected. We conclude that both endovascular and surgical treatment of SDAVFs resulted in a good and lasting clinical outcome in the majority of cases. In specific situations, when a secondary neurosurgical approach was required after endovascular treatment to achieve complete occlusion of the SDAVF, the clinical outcome was rather poor. The best first line treatment modality for each individual patient should be determined by an interdisciplinary team. (orig.)

    A 31-year-old male patient with a fatal thrombosis of the internal carotid artery caused by gun shot injury was presented in this case report. The patient was referred to the hospital with a diffuse edema on his left cheek. On otolaryngologic examination, there was a bullet entrance hole at the left mandibular corpus. No exit hole could be found. The finding from his axial computed tomography of neck and paranasal sinuses was normal. On neurological examination, a dense right hemiparesis was observed. In his cerebral angiogram, left common carotid artery was totally obliterated. Diffuse ischemia was observed in the left cerebral hemisphere. Despite intensive interventions, the patient died 4 days after the accident. In the autopsy, a large thrombosis was obtained in the left common carotid artery. This case emphasizes a fatal kinetic energy effect in vascular structures. It is stressed that a gun shot injury could be fatal with its indirect kinetic energy effects at subacute phase.

  11. Sick sinus syndrome: a review.

    Sick sinus syndrome refers to a collection of disorders marked by the heart's inability to perform its pacemaking function. Predominantly affecting older adults, sick sinus syndrome comprises various arrhythmias, including bradyarrhythmias with or without accompanying tachyarrhythmias. At least 50 percent of patients with sick sinus syndrome develop alternating bradycardia and tachycardia, also known as tachy-brady syndrome. Sick sinus syndrome results from intrinsic causes, or may be exacerbated or mimicked by extrinsic factors. Intrinsic causes include degenerative fibrosis, ion channel dysfunction, and remodeling of the sinoatrial node. Extrinsic factors can be pharmacologic, metabolic, or autonomic. Signs and symptoms are often subtle early on and become more obvious as the disease progresses. They are commonly related to end-organ hypoperfusion. Cerebral hypoperfusion is most common, with syncope or near-fainting occurring in about one-half of patients. Diagnosis may be challenging, and is ultimately made by electrocardiographic identification of the arrhythmia in conjunction with the presence of symptoms. If electrocardiography does not yield a diagnosis, inpatient telemetry monitoring, outpatient Holter monitoring, event monitoring, or loop monitoring may be used. Electrophysiologic studies also may be used but are not routinely needed. Treatment of sick sinus syndrome includes removing extrinsic factors, when possible, and pacemaker placement. Pacemakers do not reduce mortality, but they can decrease symptoms and improve quality of life.

    Purpose: Mucoceles of the sphenoid sinus represent 1-2% of all paranasal sinus mucoceles. The aim of this paper is to report our experiences in patients with mucoceles of the sphenoid sinus. Patients and method: In a period of 4 years, we observed six patients in whom a mucocele of the sphenoid sinus was suggested pre- or intraoperatively. Symptoms and signs included headache, visual loss and palsies of the III and VI cranial nerve. All patients were investigated by MRI and/or CT. Imaging findings were compared with operative and/or histological findings. Results: In three cases there were simple mucoceles, in one case we found a tumour (nasopharyngeal carcinoma) associated mucocele and in two cases, malignant tumours (carcinoma, chordoma) imitated a mucocele. The diagnosis of simple mucoceles was no problem at all by imaging. Difficulties made the two malignant tumours and the tumour associated mucocele. In the first two cases, repeated histological samples were necessary to make the final diagnosis. Conclusion: Mucoceles of the sphenoid sinus should be investigated and handled very carefully with regard to differential diagnoses and tumour associated cases.

    Full Text Available Background: Individual identification is a subtle concept and often one of the most important priorities in mass disasters, road accidents, air crashes, fires, and even in the investigation of criminal cases. Matching specific features detected on the cadaver with data recorded during the life of an individual is an important aspect in forensics, and can be performed by fingerprint analysis, deoxyribonucleic acid matching, anthropological methods, radiological methods and other techniques which can facilitate age and sex identification. Sinus radiography is one such method that has been used for determination of the sex of an individual. Hence, an attempt is being made to use the different dimensions of the maxillary sinus in the determination of sex using coronal and axial sections of plain computed tomography (CT scan. Materials and Methods: A total of 30 patients including 17 male and 13 female, visiting the Outpatient Department of the Mamata General Hospital were included as the study subjects. The dimensions of right and left maxillary sinuses of 30 subjects from plain CT were measured using SYNGO software and statistical analysis was done. Results: Sex determination using height, length, width, and volume of the maxillary sinus on both sides showed statistically significant results with a higher percentage of sexual dimorphism in the case of volume. Conclusion: Volume of the right maxillary sinus can be used as accurate diagnostic parameter for sex determination.

    Full Text Available We report a case of a young woman, with a history of a miscarriage and a molar pregnancy, who developed headache and status epilepticus in postpartum day three. Posterior reversible encephalopathy syndrome (PRES and cerebral venous and sinus thrombosis (CVST can present with identical clinical picture; however, the imaging findings can help the clinician to make the correct diagnosis and initiate the appropriate treatment. Both PRES and CVST are medical emergencies and fully reversible entities especially when treatment initiation is immediate.

  16. Deep vein thrombosis in pregnancy.

    Colman-Brochu, Stephanie

    2004-01-01

    This article provides a review of the incidence, pathophysiology, and treatment of deep vein thrombosis (DVT) in pregnancy, a rare but serious complication of pregnancy. The incidence of DVT in pregnancy varies widely, but it is a leading cause of maternal morbidity in both the United States and the United Kingdom. Risk factors during pregnancy include prolonged bed rest or immobility, pelvic or leg trauma, and obesity. Additional risk factors are preeclampsia, Cesarean section, instrument-assisted delivery, hemorrhage, multiparity, varicose veins, a previous history of a thromboembolic event, and hereditary or acquired thrombophilias such as Factor V Leiden. Heparin is the anticoagulant of choice to treat active thromboembolic disease or to administer for thromboprophylaxis, but low molecular-weight heparin is being used with increasing frequency in the pregnant woman. Perinatal nurses should be aware of the symptoms, diagnostic tools, and treatment options available to manage active thrombosis during pregnancy and in the intrapartum and postpartum periods.

    Migraine animal models generally mimic the onset of attacks and acute treatment processes. A guinea pig model used the application of meta-chlorophenylpiperazine (mCPP) to trigger immediate dural plasma protein extravasation (PPE) mediated by 5-HT2B receptors. This model has predictive value for antimigraine drugs but cannot explain the delayed onset of efficacy of 5-HT2B receptor antagonists when clinically used for migraine prophylaxis. We found that mCPP failed to induce dural PPE in mice....

    2016-07-01

    Frontotemporal brain sagging syndrome is a dementia associated with hypersomnolence, personality changes, and features of intracranial hypotension on magnetic resonance imaging. The literature is sparse with respect to treatment options; many patients simply worsen. We present a case in which this syndrome responded to lumbar dural reduction surgery. Postoperative magnetic resonance imaging indicated normalization of brain sagging and lumbar intrathecal pressure. Although no evidence of cerebrospinal leak was found, extremely thin dura was noted intraoperatively, suggesting that a thin and incompetent dura could result in this low-pressure syndrome. Clinicians who encounter this syndrome should consider dural reduction surgery as a treatment strategy.

    Arterial supply and venous drainage at the foramen magnum is variable. Two main forms of clinical presentation, intracranial and spinal, can be differentiated when a dural arteriovenous fistula (DAVF) is found at this level. We describe a case of a 68-year-old patient with a progressive paraparesis, diagnosed of dural arteriovenous fistula located at the posterior lip of foramen magnum. We review, in this setting, the vascular radiological anatomy of those fistulas and its important correlation with neurologic clinical symptoms. Copyright © 2016 Sociedad Española de Neurocirugía.

    Full Text Available A 20-year-old woman was admitted to a Gynecology Hospital in her 6th month of pregnancy for high blood pressure and tonic-clonic seizure. Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Sys-temic lupus erythematosus and secondary antiphospholipid (APS was confirmed. The patient had headache that continued several days after cesarean section, therefore, brain magnetic resonance im-aging (MRI and magnetic resonance venography (MRV were performed, and cerebral vein thrombosis was documented. Distal segment of right lateral sinus and sigmoid sinus were not ap-peared in brain MRV. Abnormal hypersignal intensity of right lateral sinus/coronal T2 was detected. Thrombolytic therapy with 20 mg tissue plasminogen activator on right sigmoid and transverse sinus was performed by an interventional neurologist. After this procedure, the patient's headache healed and she was discharged in a good condition.

    Increased intracranial pressure is common in cerebral venous thrombosis (CVT), but hydrocephalus is rarely reported in these patients. We examined the frequency, pathophysiology and associated clinical manifestations of hydrocephalus in patients with CVT admitted to our hospital between 2000 and 2010 (prospectively since July 2006). Hydrocephalus was defined as a bicaudate index larger than the 95th percentile for age, and/or a radial width of the temporal horn of ≥ 5 mm. We excluded patients in whom hydrocephalus was caused by a disease other than CVT or if it was iatrogenic. 20 out of 99 patients with CVT had hydrocephalus. 6 patients with hydrocephalus were excluded from the analysis. Patients with hydrocephalus more often had focal neurological deficits (86 vs. 49%, p = 0.02) and were more frequently comatose (43 vs. 16%, p = 0.06), as compared to patients without hydrocephalus. Deep cerebral venous thrombosis (64 vs. 9%, p hydrocephalus. Intraventricular hemorrhage was present in 1 patient with hydrocephalus, compared to none among patients without hydrocephalus (7 vs. 0%, p = 0.15). Outcome at follow-up was worse in patients with hydrocephalus (mRS 0-1, 36 vs. 68%, p = 0.02; mortality 29 vs. 9%, p = 0.07). Hydrocephalus occurs more frequently in cerebral venous thrombosis than previously believed, especially in patients with deep cerebral venous thrombosis and edema of the basal ganglia. The presence of hydrocephalus is associated with a worse clinical outcome, but a direct causal relation is unlikely. Routine shunting procedures are not advisable.

    Pilonidal sinuses usually occur in the sacrococcygeal area in young men, and occasionally can be found in other ectopic sites. We present a retrospective case review on unusual locations of pilonidal sinuses in the past 4 years. The lesion sites were as follows: one on the penis, two on the scalp, two on the abdomen, one on the neck, two in the groin and two in the axilla. Abdominal and penile lesions are uncommon, but the other locations reported are unusually rare. To our knowledge, the groin has not been reported previously as a site of a pilonidal sinus, although the histological appearance of hidradenitis suppurativa may well resemble it. When trying to clarify the pathogenesis of these occurrences, we found that recurrent hair removal was a common characteristic of the patients we contacted, and this may have been the initiating trauma.

    An osteoblastoma is a benign bone tumor that most often occurs in the vertebral column and the long bones of the extremities. Paranasal sinus involvement is very rare. We report an osteoblastoma of the ethmoid sinus in a 13-year-old boy who presented with exophthalmos. CT demonstrated an expansile, lesion of the right ethmoid sinus, which caused the orbital contents to be compressed and deviated to the right. A mixture of ground glass opacity and dense bone was present. The less dense portions of the lesion showed intense enhancement on MRI; a signal void was present on all sequences in the densely sclerotic areas. Curettage was performed. Histologically, the lesion was composed of proliferating osteoblasts along with small trabeculae of woven bone and rich vascular fibrous stroma. The literature concerning occurrence of osteoblastoma in this unusual location is reviewed and discussed. (orig.)

    2015-08-01

    Although cavernous sinus (CS) dural arteriovenous fistulas (d-AVFs) are usually treated with transvenous embolization (TVE) via the inferior petrosal sinus (IPS), IPSs are sometimes thrombosed and angiographically invisible. In such cases, the first obstacle to TVE is detecting the entry to the IPS. We report a new technique for TVE via IPS using intravascular ultrasonography (IVUS). Three consecutive cases of CS d-AVF with ipsilateral or bilateral IPS occlusion were involved in this study. On TVE, the orifice of the IPS was investigated with IVUS placed in the jugular vein or jugular bulb. This technique has been successfully adapted in all three cases. In two of these cases, IPS was well visualized with the help of IVUS, and TVE was successfully performed. To our knowledge, this is the first report to mention the usefulness of IVUS for detecting angiographically occult IPS.

    2015-10-01

    Arterial thrombosis of the hand occurs infrequently but may result in considerable morbidity and compromise of hand function. The hand surgeon may be called upon to direct management in cases of acute arterial thrombosis of the hand and should have an understanding of the available diagnostic tools and treatment modalities. This article discusses the vascular anatomy of the hand and clinical manifestations of arterial thrombosis. Differences between isolated thrombosis and diffuse intravascular injury are detailed, and treatment options for these conditions are described. Appropriate care often requires coordination with interventional radiologists or vascular surgeons. Outcomes after treatment of arterial thrombosis of the hand are variable, and prognosis may be related to whether isolated thrombosis or diffuse intravascular injury is present.

    Pregnancy increases the risk of thrombosis four- to five-fold. Seventy-five to eighty percent of pregnancy-related thrombotic events are venous and twenty to -twenty-five percent are arterial. The main reason for the increased risk is hypercoagulability. Women are hypercoagulable because they have evolved so that they are protected against the bleeding challenges of pregnancy, miscarriage, or childbirth. Both genetic and acquired risk factors can further increase the risk of thrombosis. The maternal consequences of thrombosis of pregnancy include permanent vascular damage, disability, and death. While the maternal outcomes of thrombosis can be modified by anticoagulation therapy, management of thrombosis during pregnancy is the subject of another paper in this issue (see paper by B. Konkle). This review will focus on the epidemiology, pathophysiology, risk factors, and maternal consequences of thrombosis in pregnancy.

  12. Thrombosis in end-stage renal disease.

    Although renal failure has classically been associated with a bleeding tendency, thrombotic events are common among patients with end-stage renal disease (ESRD). A variety of thrombosis-favoring hematologic alterations have been demonstrated in these patients. In addition, "nontraditional" risk factors for thrombosis, such as hyperhomocysteinemia, endothelial dysfunction, inflammation, and malnutrition, are present in a significant proportion of chronic dialysis patients. Hemodialysis (HD) vascular access thrombosis, ischemic heart disease, and renal allograft thrombosis are well-recognized complications in these patients. Deep venous thrombosis and pulmonary embolism are viewed as rare in chronic dialysis patients, but recent studies suggest that this perception should be reconsidered. Several ESRD treatment factors such as recombinant erythropoietin (EPO) administration, dialyzer bioincompatibility, and calcineurin inhibitor administration may have prothrombotic effects. In this article we review the pathogenesis and clinical manifestations of thrombosis in ESRD and evaluate the evidence that chronic renal failure or its management predisposes to thrombotic events.

    Full Text Available Paranasal sinus mucoceles are benign cystic lesions, filled with mucus, occurring due to an obstruction of involved sinus ostium. They are indolent, locally expansive, and destructive. Surgical treatment must be performed and, when done at the correct time, may prevent sequelae. We present a case of ethmoid sinus mucocele with orbit involvement and permanent optical nerve injury.

  14. Morphometric study of maxillary sinus by computed tomography. Assessment of sinus floor bone reconstruction

    Rehabilitation with dental implants in posterior maxilla is difficult because of the presence of maxillary sinus with anatomical variations. The aim of this research was to evaluate the sinus volume to install one or more implants without invading the sinus membrane. Forty (40) maxillary sinuses were evaluated in 22 skulls by computed tomography measuring in the axial, coronal and sagittal slice. The sinus were classified according to the remaining alveolar bone and a dental implant in the pl...

    Venous thrombosis, including deep vein thrombosis and pulmonary embolism, occurs at an annual incidence of about 1 per 1000 adults. Rates increase sharply after around age 45 years, and are slightly higher in men than women in older age. Major risk factors for thrombosis, other than age, include exogenous factors such as surgery, hospitalization, immobility, trauma, pregnancy and the puerperium and hormone use, and endogenous factors such as cancer, obesity, and inherited and acquired disorde...

    2016-07-01

    Full Text Available Portal venous system, apart from the main portal vein, includes its tributaries: superior and inferior mesenteric vein, as well as splenic vein, so the term portal venous thrombosis encompasses a broad spectrum of pathological conditions. Usually, one or more causative factors can be recognized, either local endothelial/ flow disturbances, or systemic inherited /acquired conditions. Portal vein thrombosis can be associated with benign or malignant disorders. Weather we are speaking about acute or chronic thrombosis, the clinical presentation is different. Acute thrombosis can be presented in a wide range, from mild abdominal discomfort to a state of intestinal ischemia and life-threatening infarction. Chronic thrombosis is usually recognized when variceal bleeding or other symptoms of portal hypertension express. Fast and accurate diagnosis sometimes is a life-saving procedure, especially in acute vascular alterations. Recently, due to the improvement of imaging procedures the number of patients with diagnosed portal vein thrombosis is increasingly growing. With a negative predictive value of 98% color Doppler ultrasound is considered as imaging modality of choice in detecting portal vein thrombosis. Based on large studies it is presumed that overall risk of getting portal vein thrombosis during lifetime is 1% in general population, but much bigger 5%-15% in cirrhotic patients. Existence of specific ultrasound criteria, if fulfilled, has ensured that diagnosis of portal vein thrombosis is fast and non-invasive. Procedure is convenient for the patient and healthcare providers, and above all, allows prompt treatment preventing further deterioration.

  17. Sonographic Findings in Fetal Renal Vein Thrombosis.

    Gerber, Rebecca E; Bromley, Bryann; Benson, Carol B; Frates, Mary C

    2015-08-01

    We present the sonographic findings of fetal renal vein thrombosis in a series of 6 patients. The mean gestational age at diagnosis was 31.2 weeks. Four cases were unilateral, and 2 were bilateral. The most common findings were renal enlargement and intrarenal vascular calcifications, followed by increased renal parenchymal echogenicity. Inferior vena cava thrombosis was found in 4 patients and common iliac vein thrombosis in 2. Fetal renal vein thrombosis is an uncommon diagnosis with characteristic sonographic findings. The presence of these findings should prompt Doppler interrogation of the renal vein and inferior vena cava to confirm the diagnosis.

    The aim of this study was the determination of bacteria present in maxillary and ethmoid cavities in patients with chronic sinusitis and to correlate these findings with bacteria simultaneously present in their nasopharynx. The purpose of this correlation was to establish the role of bacteria found in chronically inflamed sinuses and to evaluate if the bacteria present colonized or infected sinus mucosa. Nasopharyngeal and sinus swabs of 65 patients that underwent functional endoscopic sinus surgery were cultivated and at the same time the presence of leukocytes were determined in each swab. The most frequently found bacteria in nasopharynx were Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus spp., Streptococcus viridans and Streptococcus pneumoniae. Maxillary or ethmoidal sinus swabs yielded bacterial growth in 47 (72.31%) patients. The most frequently found bacteria in sinuses were Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella spp. and Streptococci (pneumoniae, viridans and spp.). The insignificant number of leukocytes was present in each sinus and nasopharyngeal swab. Every published microbiology study of chronic sinusitis proved that sinus mucosa were colonized with bacteria and not infected, yet antibiotic therapy was discussed making no difference between infection and colonization. Chronic sinusitis should be considered a chronic inflammatory condition rather than bacterial infection, so routine antibiotic therapy should be avoided. Empiric antibiotic therapy should be prescribed only in cases when the acute exacerbation of chronic sinusitis occurs and the antibiotics prescribed should aim the usual bacteria causing acute sinusitis. In case of therapy failure, antibiotics should be changed having in mind that under certain circumstances any bacteria colonizing sinus mucosa can cause acute exacerbation of chronic sinusitis.

    Adrenomedullin is related to the calcitonin gene-related peptide (CGRP) family and is present in cerebral blood vessels. It may be involved in migraine mechanisms. We measured the change in dural and pial artery diameter, mean arterial blood pressure and local cerebral blood flow flux (LCBFFlux...... adrenomedullin-(22-52). I.v. infusion of 15 µg kg- 1 adrenomedullin (n = 8) induced dilatation of dural (32 ± 7.5%) and pial (18 ± 5.5%) arteries, a reduction in mean arterial blood pressure (19 ± 3%) and an increase in LCBFFlux (16 ± 8.4%). The duration of the responses was 25 min for the dural artery, while...... arterial blood pressure. No significant inhibition of LCBFFlux was found. The antagonist alone had no effect on mean arterial blood pressure or LCBFFlux. In conclusion, we suggest that adrenomedullin in the rat cranial circulation dilates dural and pial arteries, reduces mean arterial blood pressure...

    The aim of this paper is to describe clinical and imaging findings in three patients with ventral dural defects and herniation of the spinal cord or cauda equina. The literature is reviewed and the clinical, radiological and operative findings are compared. Three patients with ventral dural defects of different etiologies are presented. One patient gave a longstanding history of ankylosing spondylitis, the second patient presents 37 years after spinal trauma, and the third patient presents with spontaneous spinal cord herniation. All patients had typically slowly progressive neurological symptoms with multiple hospitalizations until diagnosis was made. Characteristic findings in postmyelographic CT included a ventral or ventrolateral displacement with deformation of the spinal cord or the cauda equina. Sagittal MRI showed this abrupt and localized anterior deviation of the spinal cord or the cauda equina to the posterior portions of a vertebral body with or without a bony vertebral defect optimally. Additionally, due to the ventral displacement of the spinal cord, the dorsal subarachnoid space was relatively enlarged without evidence of an arachnoid cyst, in all patients. Magnetic resonance imaging and postmyelographic CT can diagnose ventral dural defects with spinal cord herniation or nerve root entrapment. Dural defects must be considered in the presence of neurological symptoms in cases of longstanding ankylosing spondylitis, late sequelae of fractures of vertebral bodies, and without history of spinal trauma or surgery.

    2009-01-01

    Meningiomas of the spine occur in the thoracic spine in approximately 80%, followed in frequency by the cervical and lumbar regions. The treatment of spinal meningiomas is complete surgical resection. As intraspinal meningiomas are almost always adherent to the dura, extensive dural resection or diathermic treatment of the dural attachment is usually performed to prevent tumor recurrence. The authors present the case of lumbar spinal meningioma in 82-year-old woman. Successful resection with preservation of the dura mater using the technique of Saito et al. (Spine 26:1805-1808, 2001) is described: After lumbar laminectomy a small incision was made in the surface of the spinal dura. The dura mater was separated into its inner and outer layers, and the tumor was resected with inner layer alone, preserving the outer layer. The outer layer is simply closed to achieve a watertight seal. The pathologic diagnosis was metaplastic (osseous) meningioma. Almost full recovery of the neurologic deficit was attained. Neither complication nor tumor recurrence has occurred in the 5 years since surgery. Dural preservation during surgical resection of spinal meningioma obviates the need for dural reconstruction and should reduce surgical morbidity. However, the patient should be followed long-term to watch for recurrence. PMID:19219468

    The central nervous system (CNS) is considered an organ devoid of lymphatic vasculature. Yet, part of the cerebrospinal fluid (CSF) drains into the cervical lymph nodes (LNs). The mechanism of CSF entry into the LNs has been unclear. Here we report the surprising finding of a lymphatic vessel network in the dura mater of the mouse brain. We show that dural lymphatic vessels absorb CSF from the adjacent subarachnoid space and brain interstitial fluid (ISF) via the glymphatic system. Dural lymphatic vessels transport fluid into deep cervical LNs (dcLNs) via foramina at the base of the skull. In a transgenic mouse model expressing a VEGF-C/D trap and displaying complete aplasia of the dural lymphatic vessels, macromolecule clearance from the brain was attenuated and transport from the subarachnoid space into dcLNs was abrogated. Surprisingly, brain ISF pressure and water content were unaffected. Overall, these findings indicate that the mechanism of CSF flow into the dcLNs is directly via an adjacent dural lymphatic network, which may be important for the clearance of macromolecules from the brain. Importantly, these results call for a reexamination of the role of the lymphatic system in CNS physiology and disease.

  6. Unusual ocular manifestations of silent sinus syndrome

    2014-01-01

    Full Text Available Silent sinus syndrome is an acquired condition in which there is a gradual collapse of the orbital floor and inward retraction of the maxillary sinus (atelectasis of the maxillary sinus. This in turn may cause associated ocular occurrences of enophthalmos and hypotropia. This is a report of an 8 year-old boy with silent sinus syndrome and associated ocular motility disorders. The association between silent sinus syndrome and ocular motility disturbance has been recently described in the literature. However, this is an infrequent association, mainly in childhood.

    Background: We report the concurrence of a spinal dural arteriovenous fistula (DAVF) and multiple perimedullary arteriovenous fistulas (PAVFs) presenting with subarachnoid hemorrhage (SAH). Moreover, the bleeding site was detected 1 month after onset. Case Description: A 56-year-old man was admitted to our hospital with an SAH. A DAVF and two PAVFs were detected at the C2 level by two rounds of digital subtraction angiography. The source of bleeding, an aneurysm on the feeding artery of PAVF, was detected at the second angiogram, which was performed 1 month after the onset of SAH. The aneurysm was not demonstrated at initial angiogram because of thrombosis in the aneurysm. The DAVF was interrupted by transarterial embolization, and the two PAVFs were subsequently treated with surgery. Conclusion: A part of the whole AVFs or the source of bleeding may be invisible in the acute stage just after hemorrhage. Repeated angiography is necessary to diagnose such complex AVFs especially in case of an SAH and treatment should be performed during the subacute stage. PMID:28217381

    The depth of the frontal sinus was measured using axial computed tomography (CT) images to examine the safety of frontal sinus trephination at selected distances from the midline. Review of 200 sinus CT scans. Two hundred sinus CT scans (400 frontal sinuses) were reviewed to measure the frontal sinus depth at 5 mm, 10 mm, and 15 mm from midline. Males had a significantly deeper frontal sinus than females at all measurements points (P trephine instruments (7 mm) and would risk penetration of the posterior table of the sinus. Of all frontal sinuses studied, 9.54% were trephine instruments, surgeons should recognize that up to 15% of nonhypoplastic frontal sinuses may not be sufficiently deep at a given point to allow safe trephination without risking unintentional transgression of the posterior table. This study suggests that trephination routinely carried out at a given predetermined distance from the midline may be an unsafe practice. Careful evaluation of the imaging is essential in every case to avoid inadvertent injury and to help select the safest distance from the midline for frontal sinus trephination.

    2014-06-01

    We report herein on 5 patients with odontogenic maxillary sinusitis caused by a dental restoration (caries cutting, cavity preparation, inlay restoration). Odontogenic maxillary sinusitis was noted following dental restoration. Even though the pulp cavity and dental pulp were intact, the odontogenic maxillary sinusitis occurred caused by an apical lesion. Infection by way of the dentinal tubules was suggested to be a cause of the pathophysiology. Endoscopic sinus surgery was indicated in patients with intractable odontogenic maxillary sinusitis caused by the dental restoration. Cone-beam x-ray CT was useful for the accurate diagnosis of odontogenic maxillary sinusitis caused by a dental restoration. Physicians should thus be aware of the possibility that a tooth, which has undergone dental restoration, may cause odontogenic maxillary sinusitis.

    2013-04-01

    Allergic fungal sinusitis is thought to represent a chronic autoimmune reaction directed against fungal elements within the sinuses, and is commonly seen in individuals with a history of chronic sinusitis that is refractory to medical therapy. The authors present a case of allergic fungal sinusitis involving the lacrimal drainage system. A 54-year-old woman initially presented with recurrent erythema and induration of the left nasolacrimal sac due to dacryocystitis, which was unresponsive to treatment with topical and systemic antibiotics. Radiological evaluation demonstrated the presence of multiple soft tissue masses along the medial canthi. During subsequent endoscopic dacryocystorhinostomy, significant amounts of allergic mucin were found within the sinuses and marked eosinophilia was present within tissue obtained from the lacrimal sac, findings highly suggestive of allergic fungal sinusitis. A diagnosis of allergic fungal sinusitis should be considered in patients presenting with epiphora in the appropriate clinical context. However, involvement of the lacrimal drainage system is an exceedingly unusual presentation.

    2000-06-01

    Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizontal position. The new elevated sinus floor, together with the inner maxillary mucosa, will create a space that can be filled with graft material. Sinus lift procedures depend greatly on fragile structures and anatomical variations. The variety of anatomical modalities in shape of the inner aspect of the maxillary sinus defines the surgical approach. Conditions such as sinus floor convolutions, sinus septum, transient mucosa swelling and narrow sinus may form a (usually relative) contra-indication for sinus floor elevation. Absolute contra-indications are maxillary sinus diseases (tumors) and destructive former sinus surgery (like the Caldwell-Luc operation). The lateral sinus wall is usually a thin bone plate, which is easily penetrated with rotating or sharp instruments. The fragile Schneiderian membrane plays an important role for the containment of the bonegraft. The surgical procedure of preparing the trap door and luxating it, together with the preparation of the sinus mucosa, may cause a mucosa tear. Usually, when these perforations are not too large, they will fold together when turning the trap door inward and upward, or they can be glued with a fibrin sealant, or they can be covered with a resorbable membrane. If the perforation is too large, a cortico-spongious block graft can be considered. However, in most cases the sinus floor elevation will be deleted. Perforations may also occur due to irregularities in the sinus floor or even due to immediate contact of sinus mucosa with oral mucosa. Obstruction of the antro-nasal foramen is, due to its high location, not a

  20. A Patient with Recurrent Arteriovenous Graft Thrombosis.

    Science.gov (United States)

    Allon, Michael

    2015-12-01

    Arteriovenous grafts (AVGs) are prone to frequent thrombosis that is superimposed on underlying hemodynamically significant stenosis, most commonly at the graft-vein anastomosis. There has been great interest in detecting AVG stenosis in a timely fashion and performing preemptive angioplasty, in the belief that this will prevent AVG thrombosis. Three surveillance methods (static dialysis venous pressure, flow monitoring, and duplex ultrasound) can detect AVG stenosis. Whereas observational studies have reported that surveillance with preemptive angioplasty substantially reduces AVG thrombosis, randomized clinical trials have failed to confirm such a benefit. There is a high frequency of early AVG restenosis after angioplasty caused by aggressive neointimal hyperplasia resulting from vascular injury. Stent grafts prevent AVG restenosis better than balloon angioplasty, but they do not prevent AVG thrombosis. Several pharmacologic interventions to prevent AVG failure have been evaluated in randomized clinical trials. Anticoagulation or aspirin plus clopidogrel do not prevent AVG thrombosis, but increase hemorrhagic events. Treatment of hyperhomocysteinemia does not prevent AVG thrombosis. Dipyridamole plus aspirin modestly decreases AVG stenosis or thrombosis. Fish oil substantially decreases the frequency of AVG stenosis and thrombosis. In patients who have exhausted all options for vascular access in the upper extremities, thigh AVGs are a superior option to tunneled internal jugular vein central vein catheters (CVCs). An immediate-use AVG is a reasonable option in patients with recurrent CVC dysfunction or infection. Tunneled femoral CVCs have much worse survival than internal jugular CVCs.

    Full Text Available Background: We aimed to investigate whether there is a relationship between development of accessory maxillary osmium (AMO and chronic sinusitis. Material and Methods: A total of 100 patients who had endoscopic sinus surgery for chronic rhinosinusitis (CRS constituted the study group while 100 patients who had septoplasty were taken as the control group. The patients were examined for the presence of AMO using rigid endoscope. Results: The prevalence of AMO was 14% in the rhinosinusitis group and 9% in the control group. The difference between the groups was statistically significant (P < 0.05. Conclusion: Our study revealed that AMO prevalence is significantly higher in patients with CRS when compared with the controls. CRS may enhance perforation of fontanelle and formation of AMO.

    Acute bacterial sinusitis is common in the pediatric population. Intracranial spread of infection is a rare but life-threatening complication of acute sinusitis. Due to the infrequent presentation of this complication, there are no well-defined management protocols for the acute sinusitis. We present three pediatric cases where children presented with intracranial sepsis, and the underlying source of infection was from the paranasal sinuses. In all cases, endoscopic sinus surgery was performed in the acute setting, with the use of frontal sinus mini-trephines playing a significant role. We describe our experience and review the available literature.

    Cortical vein thrombosis (CVT) is a rare disorder, and its diagnosis is challenging. The aim of our study was to evaluate the value of different imaging modalities for the detection of CVT. Thirteen patients with CVT, either isolated (n = 3) or in combination with sinus thrombosis (n = 10), and 20 control patients without any venous pathologies were included in this study. The analysis was performed independently by three blinded readers who evaluated the following imaging modalities and sequences separately: non-enhanced computed tomography (NCCT); multi-detector row CT angiography (MDCTA); diffusion-weighted (DWI), T1-weighted (T1w), PD-weighted (PDw), T2*-weighted (T2*w), and fluid-attenuated inversion recovery-weighted (FLAIRw) magnetic resonance (MR) sequences; as well as venous MR angiography (vMRA). The sensitivity, specificity, positive (PPV) and negative predictive values, and interobserver agreement of the different modalities were calculated. T2*w showed the highest sensitivity for the detection of CVT (97.4%), followed by T1w (70%). FLAIRw and vMRA had a sensitivity of 50% and 41.7%, respectively, whereas the sensitivity of NCCT, MDCTA, DWI, and PDw was below 30%. The specificity and PPV of all modalities was 100%, with good to perfect interobserver agreement. T2*w was the superior MR imaging sequence for diagnosing CVT. Besides T2*w, only T1w reached a sensitivity of over 50% for CVT, followed by FLAIRw, and vMRA. On the contrary, our results suggest that NCCT but also MDCTA might not be suitable for diagnosing CVT.

    Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school. We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis in adults and children. We searched CENTRAL 2013, Issue 4, MEDLINE (January 1966 to May week 2, 2013), EMBASE (1990 to May 2013) and bibliographies of included studies. Randomised controlled trials (RCTs) comparing INCS treatment to placebo or no intervention in adults and children with acute sinusitis. Acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work. Two review authors independently extracted data, assessed trial quality and resolved discrepancies by consensus. No new trials were found for inclusion in this update. Four studies involving 1943 participants with acute sinusitis met our inclusion criteria. The trials were well-designed and double-blind and studied INCS versus placebo or no intervention for 15 or 21 days. The rates of loss to follow-up were 7%, 11%, 41% and 10%. When we combined the results from the three trials included in the meta-analysis, participants receiving INCS were more likely to experience resolution or improvement in symptoms than those receiving placebo (73% versus 66.4%; risk ratio (RR) 1.11; 95% confidence interval (CI) 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement of symptoms or complete relief: for mometasone furoate 400 µg versus 200 µg (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and

    The purpose of this study was to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). The author examined the extent and the recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus (67.9%), posterior ethmoid sinus (48.9%), frontal sinus (42.0%) and sphenoid sinus (41.4%). The characteristic features of CT images of the sinusitis were sinus opacification (22.4%), mucoperiosteal thickening (34.3%), and polyposis (2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babbel's classification. They were 1) infundibular (13.0%), 2) ostiomeatal unit (67.4%), 3)sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns (18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus, both posterior sinuses were 11.4%, 66.8%, 6.3%, respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%, 79.2%, 45.1% respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess 5.2%. The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns and the proximity of the important structures to the posterior paranasal sinuses.

    Sinus osteoma is a common nasal and sinus disease, while the clinical cases of osteoma with a diameter greater than 30 millimeter are rarely seen. This paper reports a case of a 39-years-old male patient discovered with one-year long swelling pain in the right eye. The patients' right eye was mildly prominent and he suffered from hypopsia and diplopia. After CT scanned, he have ethmoid osteoma been discovered, besides, the right media rectus compression and orbital apex compression and consequent pathologically were diagnosed. The solid tumor ranged widely from the anterior skull base to the superior and interior orbital walls,and thus deprived the patient's complete surgical resection. As an attempt to prevent complications, most parts of the tumors were sur gically removed.

    A 55-year-old male patient was referred to our clinic with signs and symptoms of recurring sinusitis after a right maxillary sinus floor augmentation for implantological purposes. Investigations showed an antibiotic-resistant ethmoidomaxillary sinusitis resulting from bone graft infection and displacement of previously inserted xenograft material into the maxillary sinus. The patient thus underwent a surgical procedure combining nasal endoscopy and oral surgery in order to remove the infected graft and restore sinusal drainage. The procedure was apparently successful but sinusitis relapsed after surgery and persisted despite 2 weeks of antibiotic therapy and local medications. A CT scan showed persistence of grafting fragments in the maxillary sinus. A new surgical procedure was scheduled while a more accurate endoscopic local medication was performed. Six hours after the treatment, the patient spontaneously expelled the fragments and promptly recovered. The patient successfully underwent another maxillary sinus floor augmentation procedure 6 months later. PMID:23234824

    Full Text Available Abstract Introduction Renal vein thrombosis, although rare in adults, is well recognized in neonates and is one of the most common manifestations of neonatal thromboembolic events. The etiology of renal vein thrombosis remains unidentified in the majority of cases. We report a case of renal vein thrombosis in a neonate associated with elevated maternal lipoprotein (a. Case presentation A full-term female infant, appropriate for gestational age, was born via spontaneous vaginal delivery to an 18-year-old primigravida. The infant's birth weight was 3680 g and the Apgar scores were eight and nine at 1 and 5 minutes respectively. Evaluation of the infant in the newborn nursery revealed a palpable mass in the right lumbar area. Tests revealed hematuria and a high serum creatinine level of 1.5 mg/dl. An abdominal ultrasound Doppler flow study demonstrated an enlarged right kidney, right renal vein thrombosis, and progression of the thrombosis to the inferior vena cava. There was no evidence of saggital sinus thrombosis. An extensive work-up of parents for hypercoagulable conditions was remarkable for a higher plasma lipoprotein (a level of 73 mg/dl and an elevated fibrinogen level of 512 mg/dl in the mother. All paternal levels were normal. The plasma lipoprotein (a level in the neonate was also normal. The neonate was treated with low molecular weight heparin (enoxaparin at 1.5 mg/kg/day every 12 hours for 2 months, at which time a follow-up ultrasound Doppler flow study showed resolution of the thrombosis in both the renal vein and the inferior vena cava. Conclusion There have been no studies to date that have explored the effect of abnormal maternal risk factors on fetal hemostasis. A case-control study is required to investigate whether elevated levels of maternal lipoprotein (a may be a risk factor for neonatal thrombotic processes. Although infants with this presentation are typically treated with anticoagulation, there is a lack of evidence

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    Eichinger, Sabine

    2016-04-01

    Deep vein thrombosis of the leg and pulmonary embolism are frequent diseases and cancer is one of their most important risk factors. Patients with cancer also have a higher prevalence of venous thrombosis located in other parts than in the legs and/or in unusual sites including upper extremity, splanchnic or cerebral veins. Cancer also affects the risk of arterial thrombotic events particularly in patients with myeloproliferative neoplasms and in vascular endothelial growth factor receptor inhibitor recipients. Several risk factors need to interact to trigger thrombosis. In addition to common risk factors such as surgery, hospitalisation, infection and genetic coagulation disorders, the thrombotic risk is also driven and modified by cancer-specific factors including type, histology, and stage of the malignancy, cancer treatment and certain biomarkers. A venous thrombotic event in a cancer patient has serious consequences as the risk of recurrent thrombosis, the risk of bleeding during anticoagulation and hospitalisation rates are all increased. Survival of cancer patients with thrombosis is worse compared to that of cancer patients without thrombosis, and thrombosis is a leading direct cause of death in cancer patients.

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

    Full Text Available BACKGROUND In 1825, Ribes, a French physician, described the foremost detailed explanation of Cerebral Venous Sinus Thrombosis (CVST. Infective causes, thrombophilic abnormalities, oral contraceptives, antithrombin III, protein C and protein S defects, antiphospholipid syndrome, high plasma concentrations of homocysteine, low plasma folate level are common causes of CVT. The prognosis after CVT during pregnancy and puerperium is probably better than after CVT from other causes. During the past decade, increased awareness of the diagnosis improved neuroimaging techniques and more effective treatment have improved the prognosis. MATERIALS AND METHODS 32 patients admitted to SSG Hospital from November 2012 to November 2013 with a confirmed diagnosis of cerebral venous thrombosis by imaging of brain (MR Veno were included. Meticulous history, clinical examination and laboratory investigations were carried out in all cases. Haemorrhagic thromboembolic stroke and metabolic encephalopathy were excluded from study. RESULTS The puerperal CVT group consisted of 17 women (53.125% and the non-puerperal group consisted of 25 patients (78.125% of which 10 were women and 15 were men. The present study showed 42.875% of patients presented within 10 days. Headache was the most common symptom in the present study accounting for 85% of patients. In the present study, 50% of cases had seizures, 31.25% of patients had focal deficit, 53.125% of patients had altered level of consciousness and 25% of patients had papilloedema. The most common finding in the present study is haemorrhagic infarction present in 59.375% of cases. The transverse sinus is most commonly involved accounting for 65.625% followed by sigmoid sinus with 59.375% and superior sagittal sinus with 56.25%. In our study, all the 32 patients were treated with anticoagulants. All patients were subjected to LMWH and then switched on to warfarin therapy maintaining the INR value 1.5 to 2 times normal

    Due to the specific physiology associated with pregnancy and puerperium, cerebral venous sinus thrombosis (CVT) may manifest different characteristics. This study aimed to identify the clinical manifestations and prognosis of pregnancy-associated CVT. A total of 43 pregnancy-associated CVT patients were enrolled. We analysed the clinical presentations of the disease and performed a multivariate logistic regression analysis to determine which variables were associated with prognosis. Our descriptive results showed the following: 1) the incidence was 202 per 100,000 deliveries, and the mortality rate was 11.63%; 2) the most frequent symptom was headache; 3) the most frequent abnormal laboratory findings were increased levels of fibrinogen and several serum lipoproteins (including triglyceride, cholesterol, high-density lipoprotein, low-density lipoprotein, apolipoprotein A1, and apolipoprotein B); and 4) the superior sagittal sinus and transverse sinus were the most frequently affected locations. Moreover, an increased modified Rankin Scale score was positively associated with infection, seizure, intracerebral haemorrhage (ICH) and hypertensive disorders of pregnancy (HDP). Comparably, the occurrence of death was positively and significantly associated with infection, seizure and ICH. Consequently, timely diagnosis and treatment of pregnancy-associated CVT patients with infection, seizure, ICH or HDP are needed. Patients with infection, seizure or ICH have a greater risk of death.

    Acute sinusitis is the inflammation and swelling of the nasal and paranasal mucous membranes and is a common reason for patients to seek primary care consultations. The related impairment of daily functioning and quality of life is attributable to symptoms such as facial pain and nasal congestion. To assess the effects of systemic corticosteroids on clinical response rates and to determine adverse effects and relapse rates of systemic corticosteroids compared to placebo or standard clinical care in children and adults with acute sinusitis. We searched CENTRAL (2014, Issue 1), MEDLINE (1966 to February week 1, 2014) and EMBASE (January 2009 to February 2014). Randomised controlled trials (RCTs) comparing systemic corticosteroids to placebo or standard clinical care for patients with acute sinusitis. Two review authors independently assessed the methodological quality of the trials and extracted data. Five RCTs with a total of 1193 adult participants met our inclusion criteria. We judged methodological quality to be moderate in four trials and high in one trial. Acute sinusitis was defined clinically in all trials. However, the three trials performed in ear, nose and throat (ENT) outpatient clinics also used radiological assessment as part of their inclusion criteria. All participants were assigned to either oral corticosteroids (prednisone 24 mg to 80 mg daily or betamethasone 1 mg daily) or the control treatment (placebo in four trials and non-steroidal anti-inflammatory drugs (NSAIDs) in one trial). In four trials antibiotics were prescribed in addition to oral corticosteroids or control treatment, while one trial investigated the effects of oral corticosteroids as a monotherapy.When combining data from the five trials, participants treated with oral corticosteroids were more likely to have short-term resolution or improvement of symptoms than those receiving the control treatment: at days three to seven (risk ratio (RR) 1.3, 95% confidence interval (CI) 1.1 to 1

    We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despite the absence dental symptomatology, the dental origin of sinusitis was discovered. The majority of sinonasal symptoms resolved after appropriate dental treatment, and there was no need for nasal or sinus surgery.

    Full Text Available Bone suture in lateral sinus lift has four indications. Three of them depend on creating a hole in the lateral maxillary sinus wall above the antrostomy window for securing the elevated medial maxillary sinus membrane to manage perforated Schneiderian membrane. Covering the buccal antrostomy window with the buccal fat pad (BFP for better nourishment of the inserted graft and as an alternative for bone tags in fixation of collagen membrane has been reported previously. A new indication for firmly anchoring the BFP to the medial maxillary sinus wall as the last resort for the management of perforated Schneiderian membrane is explained in this article.

    Full Text Available Introduction: The osteomas are osseous lesions with slow and asymptomatic growth that most of the times is a finding in radiological exams requested for other reason. It's the most common benign neoplasm of the paranasal sinuses. The osteomas are located mainly in the frontal sinus (57% to 80%, followed by the ethmoidal sinuses (20%, maxillary sinuses and rarely in the sphenoid sinus. It has a discreet predominance in the male sex 1.5 and its incidence is higher in the 3rd and 4th decades of life. The treatment is surgical no matter the size. Objective: To describe a case of giant osteoma of the ethmoidal sinus including a brief literature review. Case Report: JDA, male, 33 years old, presented with a right constant nasal obstruction for 01 year. Upon exam, he presented with facial asymmetry with lateralization of the right ocular globe. The computed tomography of the paranasal sinuses showed a lesion with density of soft parts occupying partially the right nasal cavity, ethmoid sinus and right maxillary. The patient was submitted to surgery with full exeresis of the lesion. The anatomopathological exam confirmed osteoma. The patient evolved without evidences of the lesion recurrence. Final Comments: The osteomas in the ethmoidal sinus, irrespectively of the size and due to the risk of complications, must be operated.

    @@ Silent sinus syndrome (SSS) is characterized by spontaneous and progressive unilateral enophthalmos with no other symptoms. Maxillary sinus atelectasis displayed on CT will be helpful for clinical diagnosis. The operation for better maxillary sinus ventilation shows good therapeutic effects and prognosis. In 1964, Montgometry1 described the first case of patient whose enophthalmos was caused by mucocele of the maxillary sinus. Since then, all otolaryngologists have taken more and more attention to this syndrome. And by June 2000, a total of 45 cases had been reported worldwide.

    Patients with common cold have often symptoms similar to sinusitis. These symptoms often resolve in time, but symptomatic treatment (e.g. analgesics, decongestants) may be used. If symptoms continue for over 10 days, or severe symptoms continue for over 3 days, or symptoms turn worse in the course of the disease, bacterial sinusitis should be suspected. Diagnosis is based on clinical findings, and can be confirmed with ultrasound examination. Amoxicillin, penicillin or doxicyclin are recommended for bacterial sinusitis. Patients with chronic or recurrent sinusitis should be referred to specialist care.

    Intracranial metastases are a rare manifestation of prostate carcinoma and the dura mater is the most affected site. We report a series of six patients with dural prostate metastases (DPM) and perform a systematic review of the current literature in order to depict imaging trademarks of this condition. This review points to a magnetic resonance imaging (MRI) pattern of meningeal involvement characterized by a diffuse smooth thickening, nodular appearance or dural-based masses. We also demonstrate an osteoblastic pattern of lesions, particularly in sphenoid wing, by computed tomography (CT) scans. We suggest that these imaging findings may support an elevated index of suspicion of DPM in elderly men, including those patients without urologic symptoms.

    Deep vein thrombosis and common complications, including pulmonary embolism and post-thrombotic syndrome, represent a major source of morbidity and mortality worldwide. Experimental models of venous thrombosis have provided considerable insight into the cellular and molecular mechanisms that regulate thrombus formation and subsequent resolution. Here, we critically appraise the ex vivo and in vivo techniques used to assess venous thrombosis in these models. Particular attention is paid to imaging modalities, including magnetic resonance imaging, micro-computed tomography, and high-frequency ultrasound that facilitate longitudinal assessment of thrombus size and composition.

    A retrospective review was done on medical records of 13 patients with persistent post-dural-puncture headaches after one or more epidural blood patches. Headache occurred in nine patients with post-laminectomy syndrome after "wet taps" while performing epidural blocks. In two patients post-dural-puncture headache appeared after long term implanted intrathecal catheters were removed. In two other cases headache developed after spinal anesthesia. Treatment included bed rest, intravenous hydration and at least one epidural blood patch; three patients were given 60 milliliters of epidural saline, without success. Eight epidural catheters were inserted through the lumbar access and five through the caudal approach. Initially, a bolus of 20 milliliters of dextran-40 was given followed by an infusion of 3 mL/hr, until 12 hours after the head pain and any other related symptoms subsided. In all patients the headache disappeared within 20 hours after initiating therapy (9.55 mean hours, SD +/- 0.79). In five patients headache ceased in less than five hours. Nausea and photo-phobia subsided earlier. Patients with post-dural-puncture headache resistant to other treatments, including at least one epidural blood patch, were successfully treated by a bolus followed by continuous epidural infusion of dextran-40.

  18. Large capillary hemangioma of the temporal bone with a dural tail sign: A case report

    2014-05-13

    The present study reports a rare case of large capillary hemangioma of the temporal bone with a dural tail sign. A 57-year-old female presented with pulsatile tinnitus and episodic vertigo associated with a ten-year history of an intermittent faint headache. Magnetic resonance imaging revealed a mass in the right petrous bone, which was hypointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images, and showed a dural tail sign following gadolinium administration. Pre-operatively, this tumor was believed to be a meningioma. During surgery, the vascular tumor was removed by a modified pterional approach. A histopathological examination indicated that the tumor was a capillary hemangioma. Although intraosseous capillary hemangiomas are rare, they most frequently affect the temporal bone. Hemangiomas of the temporal bone may mimic other more common basal tumors. The diagnosis is most often made during surgical resection. The dural tail sign is not specific for meningioma, as it also occurs in other intracranial or extracranial tumors. The treatment of intratemporal hemangiomas is complete surgical excision, with radiotherapy used for unresectable lesions. To the best of our knowledge, the present study is the fourth case of intraosseous intracranial capillary hemangioma, but the largest intratemporal hemangioma to be reported in the literature to date.

    Migraine animal models generally mimic the onset of attacks and acute treatment processes. A guinea pig model used the application of meta-chlorophenylpiperazine (mCPP) to trigger immediate dural plasma protein extravasation (PPE) mediated by 5-HT2B receptors. This model has predictive value for antimigraine drugs but cannot explain the delayed onset of efficacy of 5-HT2B receptor antagonists when clinically used for migraine prophylaxis. We found that mCPP failed to induce dural PPE in mice. Considering the role 5-HT2B receptors play in hypoxia-induced pulmonary vessel muscularization, we were encouraged to keep mice under hypoxic conditions and tested whether this treatment will render them susceptible to mCPP-induced dural PPE. Following four-week of hypoxia, PPE, associated with increased transendothelial transport, was induced by mCPP. The effect was blocked by sumatriptan. Chronic application of 5-HT2B receptor or nitric oxide synthase blockers during hypoxia prevented the development of susceptibility. Here we present a migraine model that distinguishes between a migraine-like state (hypoxic mice) and normal, normoxic mice and mimics processes that are related to chronic activation of 5-HT2B receptors under hypoxia. It seems striking, that chronic endogenous activation of 5-HT2B receptors is crucial for the sensitization since 5-HT2B receptor antagonists have strong, albeit delayed migraine prophylactic efficacy.

    In this paper we reported a novel method to detect and quantify dural ectasia in Marfan syndrome. Firstly, the dural sacs of 8 Marfan patients were segmented by applying an unsupervised Fuzzy C-Means method on T2-weighed magnetic resonance images. Then, for each patient a tubular model of the dural sac was extracted by detecting and removing the existent pathological extrusions. The segmented images together with the resulting tube were then rendered using a marching cubes algorithm. The proposed algorithm represents a first attempt to quantify and to morphologically characterize the pathological ectasia that usually accompanies the Marfan disorder. The generated 3D reconstruction and the opportunity to overlap them with a physiological model provides the clinician with a tool for a panoramic view of the structures and a means for a more accurate inspection of ectasia. In addition the extracted parameters furnish quantitative and reproducible measures that could be useful as discriminative indexes for an automatic and more objective diagnosis.

    Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses.

    Dural repair products are evolving from animal tissue-derived materials to synthetic materials as well as from inert to absorbable features; most of them lack functional and structural characteristics compared with the natural dura mater. In the present study, we evaluated the properties and tissue repair performance of a new dural repair product with biomimetic design. The biomimetic patch exhibits unique three-dimensional nonwoven microfiber structure with good mechanical strength and biocompatibility. The animal study showed that the biomimetic patch and commercially synthetic material group presented new subdural regeneration at 90 days, with low level inflammatory response and minimal to no adhesion formation detected at each stage. In the biological material group, no new subdural regeneration was observed and severe adhesion between the implant and the cortex occurred at each stage. In clinical case study, there was no cerebrospinal fluid leakage, and all the postoperation observations were normal. The biomimetic structure and proper rate of degradation of the new absorbable dura substitute can guide the meaningful reconstruction of the dura mater, which may provide a novel approach for dural defect repair.

  4. The incidence of dural tears after complete resection of lumbar synovial cysts and the relation to the outcome.

    Synovial cysts in the lumbar spine are uncommon causes of radicular pain. In cases where conservative treatment fails, surgical resection is recommended. Dural adhesions are common intraoperative findings; therefore, the removal of the cyst may sometimes result in dural tears. The frequency of dural tears is greater with synovial cysts than in other lumbar surgeries. Clinical parameters and characteristics seen on magnetic resonance imaging were assessed to investigate the correlation between the outcome after surgery of lumbar synovial cysts and dural tears. This study was designed as a retrospective practice audit. Patient data were drawn from an electronic medical record system. Included were consecutive patients after microsurgical resection of symptomatic lumbar synovial cysts between May 2013 and November 2015. The surgical report was evaluated retrospectively regarding the extent of decompression and cyst resection as well as surgery-related complications. Pre-operative magnet resonance imaging was assessed concerning the reason for compression of the neural structures, the dimension of the cyst, and the signal of the cyst content in T2 images. In a follow-up examination about four weeks after surgery, the patient satisfaction index was evaluated. Forty-four consecutive patients after resection of a lumbar synovial cyst met the inclusion criteria. The mean patient satisfaction index was 2.0±1.0. Twenty-nine patients of the 38 patients with follow-up (76.3%) with a satisfaction index of 1 or 2 were rated as favorable. One revision surgery was necessary because of a cerebrospinal fluid fistula. Furthermore, in 4 patients an incidental durotomy occurred without any symptoms after surgery. Accordingly, the rate of dural tears was 11.4%. Dural tears were significantly more common in patients with a satisfaction index of 3 or 4 (P=0.04). Sixty percent of the patients with dural tears were operated on in level L5/S1 compared to 3 patients without a dural tear (P=0

    to explore the relationship between the maxillary sinus volume and the amount of alveolar bone, and the effect of molar loss upon the maxillary sinus was further analyzed,by measuring adult maxillary sinus volume, sinus ridge distance, and calculating the gasification coefficient of maxillary sinus. One hundred and ninety cases (361 maxillary sinus) with CT examinations were collected, they were divided into group A and group B, 121 cases (242 maxillary sinus) of normal subjects served as group A, 42 cases (65 maxillary sinus) with molar part off were B group, in which 31 maxillary sinus with a molar loss were group B1,22 maxillary sinus with two molar loss were B2 group,12 maxillary sinus with three molar loss (one molar remains) were B3 group, 27 cases (54 maxillary sinus) with upper teeth off were C group. Bymeasureing the maxillary sinus volume, sinus ridge distance and the size of the maxillary sinus, calculating the gasification coefficient, we analyzed the relationship between maxillary volume and sinus ridge distance, and comparatively analyzed the differences among the three groups in the size, gasification coefficient, volume of maxillary sinus and sinus ridge distance. In the normal group,the volume of maxillary sinus and sinus ridge distance had a correlation coefficient of -0. 63,(PSinus ridge distance in group A was larger than the other two groups (Pmaxillary sinus diameter and reft-right diameter in C group was greater than in A group and B group(Pmaxillary sinus is negatively correlated with the amont of alveolar bone; Upper teeth's shedding promotes maxillary sinus deformation; Maxiuary sinus volume has a tendency to decrease.

    Spontaneous thrombosis of a vein of Galen aneurysmal malformation (VOGM) is rare. We describe a 2-month-old patient with a patent VOGM and hydrocephalus, also confirmed patent at 6 months, but with subsequent lack of filling on pre-embolization catheter digital subtraction angiography (DSA) at 9 months' age. Due to the presence of T1- and T2-bright signal, noncontrast T1-weighted images (T1WI), T2-weighted images (T2WI), two-dimensional (2D) time-of-flight (TOF) magnetic resonance venography (MRV), and postcontrast T1WI were ambiguous for patency. However, subtracting the pre- from the postcontrast MRV images confirmed closure compared to subtracted images at 6 months' age. The factors contributing to thrombosis were likely a combination of a disproportionately small straight sinus, ventriculostomy, and contrast medium from DSA.

    The authors report on a new method for removing dumbbell-shaped spinal tumors that avoids the risk of postoperative cerebrospinal fluid (CSF) leakage. Adequate visualization of the intra- and extradural components of the tumor is achieved with the use of separate dural incisions. First, the dura mater is opened along the dural theca to provide adequate visualization of the intradural portion of the mass; then, a second incision is made along the nerve root to remove the extradural component. Meticulous suturing is essential in intradural lesion cases; however, the dura mater is usually thin and fragile in such cases. During suturing with a needle and thread, the dura mater can become lacerated proximal to the needle holes and result in CSF leakage. In the authors' technique, instead of using a needle and thread, nonpenetrating vascular clips were used to close the dural incisions. When operating on dumbbell-shaped spinal tumors, the authors found that the "separate-dural-incision method" was preferable to the conventional T-shaped dural incision method because no dural defects occurred after the intradural procedure and meticulous dural closure with vascular clips was achieved. The authors conclude that the novel separate-dural-incision method for removing dumbbell-shaped tumors and the use of nonpenetrating vascular clips permits reliable dural closure, prevents postoperative CSF leakage, and promises good postoperative clinical results.

Thirty-four patients who underwent OFSO for chronic frontal sinusitis ( and frontal sinus mucocele ( comprised our study group. Data reviewed included demographics, history of prior frontal sinus operation(s, imaging, diagnosis, and operative complications. Results. The age range was 19 to 76 years. Seventy percent of patients with chronic frontal sinusitis underwent OFSO as a salvage surgery after previous frontal sinus surgery failures, while 30% underwent OFSO as a primary surgery. For those in whom OFSO was a salvage procedure, the failed surgeries were endoscopic approaches to the frontal sinus (69%, Lynch procedure (12%, and OFSO outside this study period (19%. For patients with frontal sinus mucocele, 72% had OFSO as a first-line surgery. Within the total study population, 15% of patients presented for OFSO with history of prior obliteration, with a range of 3 to 30 years between representations. Conclusions. Osteoplastic frontal sinus obliteration remains a key surgical treatment for chronic inflammatory frontal sinus disease both as a salvage procedure and first-line surgical therapy.

Patients with isolated agenesis of the uncinate process underwent antibiotic treatment an average of 7 times per year, whereas those with types I, II and III maxillary sinus hypoplasia were treated 1.57, 3.22, and 5.75 times per year, respectively, over a 5-year period. The antibiotic treatment frequency for patients with isolated agenesis of the uncinate process was significantly higher than for those with types I and II maxillary sinus hypoplasia. Isolated agenesis of the uncinate process seems to play a stronger role than types I and II maxillary sinus hypoplasia in the pathophysiology of chronic sinusitis.

    The author has observed the orthopantomograms of the maxillary sinus which were taken by special exposure method to study mesiodistal dimension, shape, symmetrical relationship, bony septum of the maxillary sinus and relationship between upper lst molar and the maxillary sinus, that were selected 56 cases of 23 to 27 years old male, who have good systemic conditions and no missing teeth on upper posterior molar in normal occlusion, and obtained following conclusions: 1. Mesiodistal dimensions of the maxillary sinus are shown as follows; The mean of left dimension is 50.94 {+-} 8.34 mm and of right dimension is 49.50 {+-} 9.87 mm. 2. To the shape of the maxillary sinus, V or U shape are 33 cases(29.5%) and W shape are 77 cases (70.5%). 3. In the ralationship between upper lst molar and floor of the maxllary sinus, superimposition are 62 cases (55.36%) a nd approach are 50 cases (44.64%). 4. In the right and left symmetrical relationship of the maxillary sinus, symmetry are 37 cases (66.07%) and asymmetry are 19 cases (33.93%). 5. The bony septums in the maxillary sinuses revealed that presence of bony septums are 29 cases (25.8%) and absence ar e 83 cases (74.11%).
