Superior Sagittal Sinus Involvement Research Articles

Etiological associations of cerebral venous sinus thrombosis among adult sudanese patients: a multicenter cross-sectional study.

This was a cross-sectional hospital bases study conducted on CVST patients at four neurological centres in Khartoum state in the period from March to October 2020. Patients were studied for the aetiological association of CVST using a standardized questionnaire including medical history, clinical examination, investigation, and treatment. The study included about 60 patients, 50 of whom were female (83.3%) and 10 of whom were male (16.7%). In terms of clinical presentation, almost all patients had headache, followed by visual disturbances in 49 (81.7%), seizures in 46 (76%), disturbed consciousness in 12 (20%), and weakness in 12 (20%). The most common sign was abnormal speech, which was found in eight patients (13.3%), memory disturbances in eight patients (13.3%), evidence of CN VI lesion in three (5%), papilledema in 49 (81.7%), and hemiparesis in 46 (76.7%), while abnormal sensory signs were found in only one patient. The most common aetiological association were pregnancy in 15 (25%), oral contraceptive pills in 11(18.3%), and being in the post-partum period in 23(38.3%). All of the patients' magnetic resonant imaging/magnetic resonant venography results were abnormal. Six patients had extensive sinus involvement, 35 had superior sagittal sinus involvement, and 19 had transverse sinus involvement. After treatment, 45 patients (75%) fully recovered, 11 (18.3%) partially recovered, and 4 (6.7%) died. Post-partum, pregnancy, and oral contraceptive pills were the most common aetiological associations of CVST compared with other populations.

Utility of MRI in surgical planning for parasagittal meningiomas.

Surgical resection is the standard treatment for parasagittal meningioma (PSM), but complete resection may be challenging due to superior sagittal sinus (SSS) involvement. The SSS may be partially or completely obstructed, and collateral veins are commonly present. Thus, knowing the status of the SSS in PSM cases prior to treatment is essential to a successful outcome. MRI is utilized prior to surgery in order to determine SSS status and to check for presence of collateral veins. The objective of this study is to evaluate the reliability of MRI in predicting both SSS involvement and presence of collateral veins in subsequent comparison to actual intra-operative findings, and to report on complications and outcomes. 27 patients were retrospectively analyzed for this study. A blinded radiologist reviewed all pre-operative images, noting SSS status and collateral vein presence. Intraoperative findings were obtained from hospital records to similarly categorize SSS status and collateral vein presence. Sensitivity of the MRI to SSS status was found to be 100% and specificity was 93%. However, sensitivity and specificity of MRI to collateral vein presence was only 40% and 78.6%, respectively. Complications were experienced by 22% of patients, the majority neurologic in nature. MRI accurately predicted SSS occlusion status, but was less consistent in identification of collateral veins. These findings suggest MRI should be used with caution prior to PSM resection surgery particularly with regards to the presence of collateral veins which may complicate resection.

Late epileptic seizures following cerebral venous thrombosis: a systematic review and meta-analysis.

BackgroundIdentifying late epileptic seizures (LS) following cerebral venous thrombosis (CVT) can be useful for prognosis and management. We systematically reviewed the literature to identify risk factors for LS due to CVT.MethodsWe systematically searched PubMed, Scholar, and Scopus databases (May 2021) to identify studies reporting data on prevalence and risk factors for CVT-LS. The methodological quality was assessed with the Ottawa-Newcastle Scale. The risk of developing CVT-LS was summarized in meta-analyses and expressed as odds ratio (OR) and corresponding 95% confidence intervals (CIs) using random-effects models.ResultsOut of the 332 records retrieved, four studies were eventually included with a total of 1309 patients with CVT and 142 (11%) with CVT-LS. The most relevant predictors of CVT-LS were symptomatic seizures (OR 5.66, 95% CI 3.83–8.35), stupor/coma (OR 6.81, 95% CI 1.18–39.20), focal neurologic signs (OR 6.81, 95% CI 1.18–39.2), hemorrhagic component (OR 3.52, 95% CI 2.45–5.06), and superior sagittal sinus involvement (OR 1.52, 95% CI 1.04–2.21).ConclusionThere are several risk factors for CVT-LS that should be considered in clinical practice. Further high-quality studies are warranted to develop predictive models for individualized risk stratification and prediction of CVT-LS.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10072-022-06148-y.

Characteristics of Cerebral Sinus Venous Thrombosis Patients Presenting with Intracerebral Hemorrhage.

Patients with cerebral venous sinus thrombosis (CVST) occasionally present with intracerebral hemorrhage (ICH). In this study, we aimed to identify predictors for ICH in CVST patients. Prospective CVST databases from three academic centers were retrospectively analyzed. CVST patients with and without ICH upon presentation were compared. Among the 404 included patients (mean age 41.8 years, 33% male), 74 (18.3%) had an ICH. The patients with ICH were older (45 ± 20.6 vs. 41.1 ± 18 years, p = 0.045), and were more often pregnant or postpartum women (15% vs. 6%, p = 0.011), or chronically hypertensive (15% vs. 5%, p = 0.001). The ICH patients had higher rates of seizures (60% vs. 15%, p < 0.001), and focal neurological deficits (53% vs. 23%, p < 0.001). The ICH group had lower rates of excellent outcome measured by 90-day mRS 0 (56.7% vs. 80.3%, p < 0.001) and higher rates of 90-day mortality (8% vs. 3%, p = 0.041). Radiological variables associated with ICH included superior sagittal sinus (SSS) thrombosis (63% vs. 36%), isolated cortical vein thrombosis (38% vs. 8%), and presence of venous infarction (34% vs. 7%) (p < 0.001 for all). Upon multivariate analysis, chronic hypertension (OR 3.7, p = 0.027), being either pregnant or postpartum (OR 4.3, p = 0.006), isolated cortical thrombosis (OR 3.5, p = 0.007), and SSS involvement (OR 3.4, p < 0.001) were independently associated with ICH upon admission. In conclusion, among CVST patients, the following present higher for ICH: pregnant or postpartum women, and individuals with chronic hypertension, cortical vein, or SSS involvement.

Evaluation of the Relationship between Epileptic Seizures and Type of Parenchymal Lesion in Patients with Cerebral Venous Thrombosis

Introduction: Epileptic seizures occur in approximately 35%–40% of patients with cerebral venous thrombosis (CVT). The relationship between parenchymal lesions and epileptic seizures in CVT has been investigated, but the most associated types of parenchymal lesions have not been determined. This study, therefore, aimed to identify high-risk groups. Methods: A total of 159 patients were diagnosed as having CVT between 2015 and 2021 at our tertiary center. The risk factors for epileptic seizures after CVT were determined. Results: A total of 159 patients who were diagnosed with having CVT, 109 (68.5%) females and 50 (31.5%) males, were included in this study. The mean ages of the women and men were 41.20 ± 14.15 years and 43.60 ± 16.30 years, respectively. We found that superior sagittal sinus involvement (P = 0.019), sigmoid sinus involvement (P = 0.010), cortical vein involvement (P &lt; 0.001), parenchymal lesion (P &lt; 0.001), and the postpartum period (P = 0.003) increased the risk of epileptic seizures. When the significant variables associated with epileptic seizures in the patients were analyzed using binary logistic regression, the most significant variable was found to be the presence of parenchymal lesions. Conclusion: We found that the most significant variable for epileptic seizures after CVT was parenchymal lesions. Juxtacortical hemorrhages and nonhemorrhagic venous infarcts were the most common causes of epileptic seizures. CVT is a heterogeneous group of diseases caused by multiple aetiologies and may show ethnic and racial differences. For this reason, more precise information can be obtained with multi-center prospective studies in our population.

Features of intracranial hemorrhage in cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) is associated with intracranial hemorrhage. To identify clinical and imaging features of CVT-associated intracranial hemorrhage. We hypothesized that higher clot burden would be associated with a higher risk of intracranial hemorrhage. We performed a retrospective analysis of an international, multicenter cohort of patients with confirmed cerebral venous thrombosis who underwent computed tomography within 2weeks of symptom onset. Clinical and imaging features were compared between patients with and without intracranial hemorrhage. Clot burden was assessed by counting the number of thrombosed venous sinuses and veins on confirmatory imaging. We enrolled 260 patients from 10 institutions in Europe and Mexico. The mean age was 42years and 74% were female. Intracranial hemorrhage was found in 102 (39%). Among them parenchymal hemorrhage occurred in 64 (63%), in addition, small juxta-cortical hemorrhage was found in 30 (29%), subarachnoid hemorrhage in 24 (24%) and subdural hemorrhage in 11 (11%). Multiple concomitant types of hemorrhage occurred in 23 (23%). Older age and superior sagittal thrombosis involvement were associated with presence of hemorrhage. The number of thrombosed venous sinuses was not associated with intracranial hemorrhage (median number IQRInterquartile ratio] of sinuses/veins involved with hemorrhage 2 (1-3) vs. 2 (1-3) without hemorrhage, p = 0.4). The high rate of intracranial hemorrhage in cerebral venous thrombosis is not explained by widespread involvement of the venous sinuses. Superior sagittal sinus involvement is associated with higher bleeding risk.

Chapter 10 - Falcine meningiomas

Falcine meningiomas (FMs) are defined as meningiomas arising from the falx, covered by the overlying brain parenchyma, and not involving the superior sagittal sinus (SSS). FMs together with parasagittal meningiomas represent the second most common location of intracranial meningioma. Clinical presentation depends on the dimensions and location of the FM. Surgery for FM removal deserves several considerations related to bridging veins, anterior cerebral artery branches, arterial feeders, SSS involvement, FM locations, and FM dimensions. In this chapter the principal aspects influencing surgical strategy are analyzed together with approaches and management.

Abstract TP423: Risk Factors for Intracranial Hemorrhage in Cerebral Venous Thrombosis

Cerebral venous thrombosis is associated with intracranial hemorrhage. The occurrence of brain bleeding complicates management and is associated with worse outcomes. We aimed to identify clinical and imaging risk factors for intracerebral hemorrhage. We hypothesized that higher clot burden would be associated with a higher risk of intracerebral hemorrhage. Methods: We performed a retrospective analysis of an international, multicenter cohort of patients with cerebral venous thrombosis who underwent CT within 2 weeks of symptom onset and who had a subsequent confirmed diagnosis of CVT on MRV, CTV or DSA. Clinical and imaging features were compared between patients with and without intracranial hemorrhage. Clot burden was assessed by counting the number of thrombosed venous sinuses and veins on confirmatory imaging. Results: We recruited 260 patients with cerebral venous thrombosis from 10 institutions in Europe and Mexico. The mean age was 42 and 74% were female. Intracranial hemorrhage was found in 102 (39%). Intracerebral hemorrhage occurred in 64 (63%), small juxtacortical hemorrhage in 30 (29%), subarachnoid hemorrhage in 24 (24%) and subdural hemorrhage in 11 (11%). Combinations of these types of hemorrhage occurred in 23 (23%). Intraparenchymal hemorrhages in multiple locations occurred in 6 (6%). Older age, presence of hematological disease and superior sagittal thrombosis involvement were significantly associated with presence of hemorrhage. The number of thrombosed venous sinuses was not associated with intracerebral hemorrhage (average number of sinuses/veins involved with hemorrhage 2.1 versus 1.9 without hemorrhage, p=0.4). Conclusion: The high rate of intracranial hemorrhage in cerebral venous thrombosis is not explained by widespread involvement of the venous sinuses. Superior sagittal sinus involvement is associated with the presence of intracranial hemorrhage.

Cerebral venous sinus thrombosis a study to assess clinical profile among female patients in a tertiary care hospital

Background: The Incidence of Cerebral Venous Thrombosis (CVT) is around 3-4 cases among one million population affecting children and young adults. In India the puerperal CVT is 10-12 times more common than western countries. Even though there is apparent “rarity” of the condition but advances in knowledge and available investigation in terms of imaging (CT scan/MRI) diagnosis can be done early for appropriate treatment and decreasing the morbidity and mortality.Methods: A prospective study was conducted at Karnataka Institute of Medical Sciences, Hubli, Karnataka from December 2014 to November 2015. A total of 36 patients were included in the study.Results: Mean age of females in the study was 27.06±9.033years. 75% had seizures, 47.2% had headache, 19.4% had focal neurological deficit, 13.9% had altered sensorium, 8.3% had cranial nerve deficits 5.6% had speech deficits. 72.22% of patients and were in peripartum period and 27.8% were non-pregnant. 72.2% had superior sagittal sinus involvement, 47.2% had transverse sinus, 47.2% had sigmoid sinus, and 13.9% had internal jugular vein and 5.6% straight sinus. 47.2% had single sinus involvement, and 52.8% had multiple sinus involvement. 94.4% patients were managed conservatively and 5.6% were managed by neurosurgical intervention. 94.4% patients survived and 5.6% had mortality.Conclusions: Cerebral venous sinus thrombosis is most common in young females during peripartum period. Early diagnosis, treatment and if necessary neurosurgical intervention has good outcome.

Pre-Operative Factors Affecting Resectability of Giant Intracranial Meningiomas

Larger intracranial tumors require extended operating times and may be associated with increased perioperative complications. There are few reports describing the experience of resecting large meningiomas > or =5cm in a variety of locations. As a group, it remains largely unknown whether these relatively rare lesions are amenable to radical resection, and what factors influence their resectability. Sixty-seven patients undergoing surgery for a large intracranial meningioma (> or =5cm in the longest dimension) between 1998 and 2004 were retrospectively reviewed. The surgeries were performed at a single institution University of California at San Francisco. Predictors of resectability were assessed via multivariate logistical regression analysis. Thirty-nine (58%) patients underwent gross total resection (GTR) (Simpson grades I/II). There were no cases of perioperative mortality. At last follow-up, symptoms improved in 39 (58%) patients, remained unchanged in 20 (30%), and were aggravated in 8 (12%). In the multivariate model for all large meningiomas, age>45 years [OR (95%CI); 0.127 (0.026-0.616), p=0.01] and superior sagittal sinus involvement [OR (95%CI); 0.160 (0.026-0.976), p=0.05] were negative predictors of GTR, while preoperative embolization [OR (95%CI); 8.087 (1.719-38.044), p=0.008] was positively associated with GTR. For only supratentorial meningiomas, superior sagittal sinus involvement [OR (95%CI); 0.077 (0.010-0.571), p=0.01] and preoperative embolization [OR (95%CI); 10.492 (1.961-56.135), p=0.006] were independently associated with GTR. This study evaluated a subset of large intracranial meningiomas > or =5cm. The results indicate that GTR can be achieved in the majority of cases with limited morbidity and mortality, where symptoms will likely improve and recurrences seldom occur. This study may provide useful insights for patients undergoing surgery for large intracranial meningiomas.

Cerebral sinovenous thrombosis and idiopathic nephrotic syndrome in childhood: report of four new cases and review of the literature

Nephrotic children are prone to develop thromboembolic complications secondary to an acquired hypercoagulable state. Cerebral sinovenous thrombosis (CSVT) is increasingly recognised in this population, but clinical characteristics and outcome are not well documented. The database of the Canadian Pediatric Ischemic Stroke Registry (Toronto Site) containing prospectively enrolled children from 1992-2004 with CSVT identified four children with NS. A pooled literature analysis retrieved 17 additional cases reports. CSVT presented in the majority of cases during the first flare or within 6 months after the onset of NS and was found to occur more often in SSNS/SDNS (n=13) than in SRNS (n=4). Clinical manifestations were non-specific and consisted primarily of seizures (n=8) and signs of raised intracranial pressure (n=16). Imaging studies revealed a predilection for superior sagittal sinus involvement (n=21) and rare parenchymal lesions (n=4). The most consistent biological risk factors were a severe hypoalbuminaemia (n=14) and, to a lesser extent, decreased antithrombin (AT) levels (n=9/16). Deficiency of other coagulation inhibitors (protein S, protein C) was not identified. Inherited thrombophilia was documented in a single case, suggesting that acquired, more than genetic, coagulation factors are involved. Anticoagulation was safe, and the outcome was good in most patients, and no recurrence of thrombotic event was reported. In conclusion, CSVT is now a well-described complication of NS with potential morbidity. A high index of suspicion is required, especially in young children with NS presenting neurological symptoms. Reliable biological predictors of CSVT are lacking.

All had angiography and surgical confirmation of partial or complete occlusion of the superior sagittal sinus (SSS). A constellation of findings indicated the presence of venous flow rerouting in the SSS: (a) nonvisualization of a segment of the SSS; (6) failure of cortical veins to reach the SSS; (c) delayed emptying of veins in the region of obstruction; and (d) reversal of normal venous flow with collateral venous channels connecting the SSS with other channels such as the lateral sinus or the middle cerebral vein. These findings also support the presence of a slowly growing tumor, usually a meningioma. Other conditions that may mimic SSS occlusion are also described.Article HistoryAccepted: July 1973Published in print: July 1974 FiguresReferencesRelatedDetailsCited ByWorld Neurosurgery, Vol. 98Neurologia i Neurochirurgia Polska, Vol. 48, No. 3Neurosurgery, Vol. 67, No. 4Contemporary Neurosurgery, Vol. 29, No. 25Computer Aided Surgery, Vol. 3, No. 1Neurosurgery, Vol. 41, No. 5Journal of Neurosurgery, Vol. 81, No. 4Neuro-Ophthalmology, Vol. 7, No. 2Neuroradiology, Vol. 11, No. 4Recommended Articles RSNA Education Exhibits RSNA Case Collection Vol. 112, No. 1 Metrics Altmetric Score PDF download
