RESUMO
Cerebral venous sinus thrombosis (CVST) is an uncommon disorder with an increased mortality risk. Data on the sex-specific clinical profile and related factors can be practical in clinical diagnosis and management. Thus, we aimed to assess CVST characteristics in Shahrekord, the most elevated city among the centers of the provinces of Iran, referred to as the Roof of Iran. In this retrospective cross-sectional study, we reviewed the hospital records of 127 CVST patients between April 2013 and June 2023 to analyze the demographic characteristics, clinical profile, disease outcomes, and risk factors. STROBE guidelines were used to report this study. Females comprised 65.3% of the study. Females' age was almost equal to male patients (37.51 ± 13.95 years vs 38.09 ± 16.18 years, Pâ =â .832), and more than half of the patients (59.1%) were married. Clinical characteristics showed no significant difference between the sexes. In contrast to males, females had multifarious risk factors. However, the main risk factors for both sexes were CVST and hypertension. Most patients had 1 sinus affected (55.9%), and the location of thrombosis was mainly in the right transverse sinus in males (38.63%) and superior sagittal sinus in females (33.73%). However, those with more than 2 affected sinuses were mostly women. Regarding radiological findings, sinusitis was significantly seen in men (18.18% vs 3.61%). Among laboratory data, females significantly had higher erythrocyte sedimentation rate levels than males (21.66 ± 24.39 vs 9.60 ± 8.55). This study indicates that among CVST patients, men have significantly higher occurrences of sinusitis, and higher levels of erythrocyte sedimentation rate were observed in women. However, no other significant differences were found. More extensive studies are essential to fully comprehend the sex-specific aspects of CVST.

PURPOSE: Sinus thrombosis is a common post-operative finding after posterior fossa surgery performed in the vicinity of the dural venous sinuses. The SARS-CoV-2 virus has been shown to confer an increased risk of venous thromboembolic events owing to eliciting a hyper-inflammatory and pro-thrombotic state. In this study, we examine the incidence of post-operative venous sinus thrombosis in patients undergoing peri-sigmoid posterior fossa surgery in the pre- and post-COVID era and investigate whether COVID infection confers an increased risk of sinus thrombosis. METHODS: A retrospective review of a single institution case series of patients underwent peri-sigmoid surgery (retrosigmoid, translabyrinthine, or far lateral) approach. Relevant clinical variables were investigated that may confer an increased risk of sinus thrombosis. RESULTS: A total of 311 patients (178 in the pre-COVID era, and 133 operated on after the pandemic began in March 2020) are included in the study. The composite incidence of sinus thrombosis seen on post-operative imaging was 7.8%. The incidence of sinus thrombosis in the pre-COVID cohort was N = 12 patients (6.7%) versus N = 12 (9%) in the post-COVID cohort (p = 0.46). A history of COVID infection was not shown to confer an increased risk of post-operative sinus thrombosis (OR: 0.61; 95% CI: 0.08-4.79, p = 0.64). Only a small number of patients (N = 7, 2.3%) required either medical or surgical intervention for post-operative sinus thrombosis. CONCLUSION: The overall incidence of post-operative sinus thrombosis is similar in the pre- and post-COVID era. The findings of this study suggest that COVID infection is not associated with a higher risk of venous sinus thrombosis.

BACKGROUND: Cerebral venous thrombosis (CVT) is an uncommon and frequently unrecognized type of stroke that affects approximately five people per million annually, accounts for 0.5 to 1% of all strokes, and is more commonly seen in young individuals. The exact incidence of CVT in India remains unknown. The risk factors for venous thrombosis in general are linked classically to the Virchow's triad of stasis of the blood, changes in the vessel wall, and changes in the composition of the blood. There have been numerous studies evaluating long-term as well as short-term outcomes in the presence of these inflammatory mediators. They have been reported to be beneficial in predicting outcome and, hence, potentially in guiding management. AIMS: Evaluation of prevailing risk factors associated with cerebral venous sinus thrombosis (CVST). Description of the distribution of newer inflammatory markers among the study population and their association with functional and neurologic outcome at 30 days following the occurrence of cerebral VST. MATERIALS AND METHODS: Approval from the Institutional Review Board was obtained. Written informed consent was given by willing patients, explained in vernacular. Relevant details were obtained via a clinical history and laboratory values and imaging data obtained from the hospital's electronic health information system, which were then recorded in the proforma. No personal identifying data was collected. The sample size for this study was lower than originally planned, owing to the coronavirus disease 2019 (COVID-19) pandemic. The patients were called for follow-up after 1 month of the detection of VST, and their neurologic status was recorded on the Glasgow Coma Scale (GCS) and functional status on the modified Rankin Scale (mRS). Descriptive analysis of baseline characteristics was done. Mann-Whitney U and Kruskal-Wallis H tests of significant difference between means for nonparametric data were used. Linear regression was carried out on the variables found to differ significantly among subpopulations having good and poor neurologic outcomes. Receiver operating characteristic (ROC) curves were then derived for both outcome categories. RESULTS: The study enrolled 30 patients, with ages from 18 to 70 years, of which 19 (63.3%) were male and 11 (36.67%) were female. No risk factor was identified in 23.3% of cases. The most common risk factor was the presence of substance abuse. Among presenting features, headaches were the most common, followed by seizures and focal neurologic deficits (83.3, 30, and 23.3, respectively). Coexisting intraparenchymal hemorrhage was seen in 46.67% of patients, with the transverse sinuses most commonly involved (28.77%). The median neutrophil-to-lymphocyte ratio (NLR) was 3.415 [interquartile range (IQR) 2.634-5.637], with median platelet-to-lymphocyte ratio (PLR) 160.728 (IQR 107.728-227.776) and median systemic immune-inflammation index (SII) 1067.883 (IQR 509.694-1522.837). The NLR, PLR, and SII values were found to differ significantly among subgroups having good and poor neurologic outcome on the mRS. PLR and SII significantly differed among subgroups with venous involvement and among subgroups with good and poor neurologic status on GCS, on admission as well as 30-day follow-up. NLR, PLR, and SII values on admission showed a positive association with poor neurologic outcomes. CONCLUSION: Here, a significant correlation is seen between the values of complete blood count (CBC)-derived inflammatory markers on admission. Higher-powered studies are needed to assess the potential benefits of incorporating these markers in existing risk stratification models to improve their predictive accuracy.

BACKGROUND AND PURPOSE: Coma is an independent predictor of poor clinical outcomes in cerebral venous thrombosis (CVT). We aimed to describe the association of age, sex, and radiological characteristics of adult coma patients with CVT. METHODS: We used data from the international, multicentre prospective observational BEAST (Biorepository to Establish the Aetiology of Sinovenous Thrombosis) study. Only positively associated variables with coma with <10% missing data in univariate analysis were considered for the multivariate logistic regression model. RESULTS: Of the 596 adult patients with CVT (75.7% women), 53 (8.9%) patients suffered coma. Despite being a female-predominant disease, the prevalence of coma was higher among men than women (13.1% vs. 7.5%, p = 0.04). Transverse sinus thrombosis was least likely to be associated with coma (23.9% vs. 73.3%, p < 0.001). The prevalence of superior sagittal sinus thrombosis was higher among men than women in the coma sample (73.6% vs. 37.5%, p = 0.01). Men were significantly older than women, with a median (interquartile range) age of 51 (38.5-60) versus 40 (33-47) years in the coma (p = 0.04) and 44.5 (34-58) versus 37 (29-48) years in the non-coma sample (p < 0.001), respectively. Furthermore, an age- and superior sagittal sinus-adjusted multivariate logistic regression model found male sex (odds ratio = 1.8, 95% confidence interval [CI] = 1.0-3.4, p = 0.04) to be an independent predictor of coma in CVT, with an area under the receiver operating characteristic curve of 0.61 (95% CI = 0.52-0.68, p = 0.01). CONCLUSIONS: Although CVT is a female-predominant disease, men were older and nearly twice as likely to suffer from coma than women.

PURPOSE: Cerebral venous sinus thrombosis (CVST) is a potentially serious complication following surgical treatment of vestibular schwannoma, a benign tumor originating from Schwann cells of the vestibulocochlear nerve. This study aimed to determine the prevalence of CVST following surgical treatment of vestibular schwannoma and the factors contributing to its occurrence. METHOD: Two independent researchers searched the global databases of PubMed, Web of Science, Scopus, and the Cochrane Library up to September 01, 2023. We employed a random-effects model for data analysis. Heterogeneity was evaluated using the I2 test. To assess the quality of the studies meeting our inclusion criteria, we employed the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS: We included 23 articles in this meta-analysis. The pooled prevalence of CVST after vestibular schwannoma surgery was 6.4% (95%CI 3.4-11.5%). The pooled prevalence of CVST following the retrosigmoid (RS), translabyrinthine (TL), and middle cranial fossa (MCF) approaches was 4.8% (95%CI 2.0-11.0%), 9.6% (95%CI 4.3-20.3%) and 9.9% (95%CI 1.6-42.2%), respectively, revealing a significant difference between the TL and the RS approaches (Odds ratio = 2.10, 95%CI 1.45-3.04, P < 0.001). The sigmoid sinus exhibited the highest post-operative thrombosis rate (7.9%), surpassing the transverse sinus (3.7%) and involvement of both sigmoid and transverse sinuses (1.6%), respectively. No significant associations were found with demographic or surgical factors. CONCLUSION: In the current meta-analysis, we identified a 6.4% CVST prevalence following vestibular schwannoma surgery, with varying rates depending on the surgical approach. No significant associations with patient or surgical factors were found, emphasizing the need for heightened clinical vigilance and further research in this context.

BACKGROUND: Limited retrospective data suggest that dural venous sinus thrombosis (DVST) in traumatic brain injury (TBI) patients with skull fractures is common and associated with significant morbidity and mortality. Prospective data accurately characterizing the incidence of DVST in patients with high-risk TBI are sparse but are needed to develop evidence-based TBI management guidelines. METHODS: After obtaining institutional approval, 36 adult patients with TBI with skull fractures admitted to an Australian level III adult intensive care unit between April 2022 and January 2023 were prospectively recruited and underwent computed tomography venography or magnetic resonance venography within 72 hours of injury. When available, daily maximum intracranial pressure was recorded. RESULTS: Dural venous sinus abnormality was common (36.1%, 95% confidence interval 22.5%-52.4%) and strongly associated with DVST (P = 0.003). The incidence of DVST was 13.9% (95% confidence interval 6.1%-28.7%), which was lower than incidence reported in previous retrospective studies. Of DVSTs confirmed by computed tomography venography, 80% occurred in patients with extensive skull fractures including temporal or parietal bone fractures in conjunction with occipital bone fractures (P = 0.006). However, dural venous sinus abnormality and DVST were not associated with an increase in maximum daily intracranial pressure within the first 7 days after injury. CONCLUSIONS: Dural venous sinus abnormality was common in TBI patients with skull fractures requiring intensive care unit admission. DVST was confirmed in more than one third of these patients, especially patients with concomitant temporal or parietal and occipital bone fractures. Computed tomography venography is recommended for this subgroup of TBI patients.

PURPOSE: We hope that by analyzing the clinical features of cerebral venous sinus thrombosis (CVST), we can help ophthalmologists reduce misdiagnosis or delayed diagnosis. DESIGN: We evaluated 47 patients with CVST in terms of clinical manifestations. METHODS: All cases were analyzed in terms of risk factors, clinical symptoms, ophthalmic examination, imaging examination and lumbar puncture. RESULTS: The body mass indices (BMIs) of 41 patients (87.2%; 95% CI, 77.7-96.8%) were≥24, which is overweight by Chinese standards. There were 22 patients (46.8%; 95% CI, 32.5-61.1%) with BMIs≥28, who were considered obese. Thirteen were hypertensive (27.7%; 95% CI, 14.9-40.5%). The initial symptoms included blurred vision (23, 48.9%; 95% CI, 34.6-63.2%), amaurosis fugax (13, 27.7%; 95% CI, 14.9-40.5%), headache (11 patients, 23.4%; 95% CI, 11.3-35.5%), dizziness (3, 6.4%; 95% CI, -0.6-13.4%), and bilateral diplopia (3, 6.4%; 95% CI, -0.6-13.4%). There were 9 patients (9, 19.2%; 95% CI, 7.9-30.4%) with blindness, 23 patients (48.9%; 95% CI, 34.6-63.2%) with pupillary abnormalities, and 40 patients (85.1%; 95% CI, 74.9-95.2%) with papilledema. Forty-three of the 45 patients who successfully underwent a routine lumbar puncture showed high intracranial pressure (91.7%; 95.6% CI, 89.6-101.6%). Finally, two cases are reported in greater detail for illustrative purposes. CONCLUSION: The main reasons interfering with the diagnosis of CVST might be its nonspecific ocular symptoms and the physicians' clinical thought process being limited to the scope of common ophthalmological diseases.

OBJECTIVES: Studies focusing on intracranial hemorrhage (ICH) in patients with cerebral venous thrombosis (CVT) are limited; thus, we aimed to identify factors associated with the occurrence of ICH in Thai patients with CVT. METHODS: This retrospective cohort study recruited patients with CVT admitted to a tertiary university-based hospital between 2002 and 2022. The baseline characteristics, clinical presentations, radiographic findings, and etiologies were compared between the ICH and non-ICH groups. The factors with p < 0.2 in the univariate analysis were further analyzed using multivariable logistic regression analysis to identify independent factors associated with ICH in patients with CVT. RESULTS: Of 228 screenings, 202 patients were eligible. The incidence rate of ICH was 36.63%. The ICH group showed a higher prevalence of focal neurological deficits (63.51% vs. 26.56%, p < 0.001), seizures (68.92% vs. 21.88%, p < 0.001), dependency status at admission (60.81% vs. 39.84%, p = 0.004), superior sagittal sinus thrombosis (71.62% vs. 39.07%, p < 0.001), superficial cortical vein thrombosis (36.49% vs. 10.16%, p < 0.001), and hormonal use (17.57% vs. 7.03%, p = 0.021) than the non-ICH group. In contrast, the ICH group showed a lower prevalence of isolated increased intracranial pressure (10.81% vs. 21.88%, p = 0.048) than the non-ICH group. Seizures (adjusted odds ratio [aOR], 4.537; 95% confidence interval [CI], 2.085-9.874; p < 0.001), focal neurological deficits (aOR, 2.431; 95% CI, 1.057-5.593; p = 0.037), and superior sagittal sinus thrombosis (aOR, 1.922; 95% CI, 1.913-4.045; p = 0.045) were independently associated with ICH in the multivariable logistic regression analysis. CONCLUSIONS: Seizures, focal neurological deficits, and superior sagittal sinus thrombosis are associated with ICH in patients with CVT.

BACKGROUND: Eagle jugular syndrome (EJS), recently identified as a cause of cerebrovascular disease (CVD) due to venous obstruction by an elongated styloid process (SP), is reported here alongside a case of concurrent de novo cerebral cavernous malformation (CCM). This study aims to explore the potential causal relationship between EJS and de novo CCM through a comprehensive literature review. METHOD: Systematic literature reviews, spanning from 1995 to 2023, focused on EJS cases with definitive signs and symptoms and de novo CCM cases with detailed clinical characteristics. Data on the pathophysiology and clinical manifestations of EJS, as well as potential risk factors preceding de novo CCM, were collected to assess the relationship between the two conditions. RESULT: Among 14 patients from 11 articles on EJS, the most common presentation was increased intracranial hypertension (IIH), observed in 10 patients (71.4%), followed by dural sinus thrombosis in four patients (28.6%). In contrast, 30 patients from 28 articles were identified with de novo CCM, involving 37 lesions. In these cases, 13 patients developed CCM subsequent to developmental venous anomalies (43%), seven following dural arteriovenous fistula (dAVF) (23%), and two after sinus thrombosis (6%). In a specific case of de novo brainstem CCM, the development of an enlarged condylar emissary vein, indicative of venous congestion due to IJV compression by the elongated SP, was noted before the emergence of CCM. CONCLUSION: This study underscores that venous congestion, a primary result of symptomatic EJS, might lead to the development of de novo CCM. Thus, EJS could potentially be an indicator of CCM development. Further epidemiological and pathophysiological investigations focusing on venous circulation are necessary to clarify the causal relationship between EJS and CCM.

INTRODUCTION: Headache after cerebral venous thrombosis (post-CVT headache [PCH]) is a common complaint during follow-up. Risk factors and their pathophysiology are not well known. We studied PCH prevalence in CVT patients, its pathophysiology, and possible risk factors. MATERIALS AND METHODS: We performed a retrospective observational study of patients admitted to a tertiary hospital between 2006 and 2019 with CVT and at least one follow-up appointment. We diagnosed PCH when patients reported headaches during the follow-up visit. Recanalization was retrospectively assessed by two neuroradiologists using the first available follow-up MRI/ MRV, and the PRIORITy-CVT study classification. RESULTS: Of 131 patients, sixty (60/131, 45.8 %) reported PCH at the 3-month follow-up. Of these PCH, 9 had previous migraine (9/60, 5.0 %) and 13 previous tension-type headaches (13/60, 21.6 %), before CVT. Forty-four (44/60, 73.3 %) PCH patients had de novo headache: 21 (21/60, 35.0 %) de novo tension-type headaches; 6 (6/60, 10.0 %) de novo migraine; 6 [(6/60, 10.0 %) secondary headache disorders: 3 due to dural arteriovenous fistula, 2 due to intracranial hypertension, and 1 recurrent CVT], and 11 other headache types. Most patients had at least partial recanalization, with no difference in PCH frequency amongst recanalization subgroups (p = 0.598). Premorbid depression (p = 0.009, OR 7.9, 95 % CI 1.6-31.4) increased the odds ratio of PCH, while superior sagittal sinus thrombosis (p = 0.005, OR 0.15, 95 % CI 0.03-0.56) decreased it. DISCUSSION: Our study shows that PCH is a common finding after CVT and elucidates potential risk factors. PCH is common in patients with previous or de novo primary headache. In PCH patients without previous headache, secondary causes of headache, namely related to CVT complications, should be excluded. PCH is also increased in patients with premorbid depression. There was no statistically significant difference in PCH amongst the PRIORITy-CVT recanalization subgroups, but most patients had at least partial recanalization.

No well-established criteria exist for assessing the risk of cerebral venous sinus thrombosis (CVST). Here, we sought to gain an understanding of CVST cases and associated risk factors, based on the rates of emergency CT venographies (CTVs) performed after hours. Furthermore, we aimed to assess possible correlations between CVST rates and COVID-19, including at the start of the COVID-19 vaccination campaign. We collected reports of emergency CTVs performed after hours at 56 Swedish hospitals between 1/1/2019 and 12/31/2022, and divided them into five groups: (I) from 1/1/2019 to 1/31/2020, before the emergence of COVID-19 cases in Sweden; (II) from 2/1/2020 to 12/26/2020, after the emergence of COVID-19 but before vaccination rollout; (III) from 12/27/2020 to 7/28/2021, from the start of the COVID-19 vaccination campaign until 50% of the adult population in Sweden had been vaccinated; (IV) from 7/29/2021 to 2/1/2022, from when 50% of the adult population was vaccinated until restrictions were lifted; and (V) from 2/2/2022 to 12/31/2022, after restriction measures were suspended. For all included patients, we collected information on demographics and clinical history, including pregnancy, recent partum, and use of oral contraceptives or post-menopausal hormone replacement therapy. In total, we collected 430 reports (92% female, 8% male). The CVST positivity rate was 22.2% in men vs. 2.3% in women. None of the pregnant (n = 49) or postpartum (n = 12) women had CVST positivity. The frequency of CTV examinations was lowest in group 2; during this period, the average time between patients being imaged was 7 days. The frequency of CTV examinations was highest in group IV; during this period, a patient underwent this type of scan every 1.5 days, on average. The frequency of CVST-positive scans was lowest in group II; during this period, a positive case was found every 66 days, on average. The frequency of CVST-positive scans was highest in group IV; during this period, a positive case was found every 62 days, on average, and no statistical difference with respect to group II was observed. Pregnancy and recent partum were not significant risk factors for CVST. The elevated CVST positivity rate observed during the height of the COVID-19 pandemic suggested that patients with less likelihood for positive CVST had fewer emergency visits. The positivity rate did not increase with the start of the COVID-19 pandemic or the rollout of COVID-19 vaccination.

BACKGROUND: Cerebral sinus venous thrombosis (CSVT) is an uncommon condition in children with potentially serious outcomes. Large epidemiological studies in children with CSVT are few. The objective of this study is to evaluate the epidemiology and in-hospital outcomes of hospitalized children with CSVT in the United States. METHODS: We performed a retrospective cross-sectional analysis of the Healthcare Cost and Utilization Project Kids' Inpatient Database for the combined years 2016 and 2019. The database was queried using the diagnoses for intracranial and intraspinal phlebitis and thrombophlebitis, nonpyogenic thrombosis of the intracranial venous system, and cerebral infarction due to cerebral venous thrombosis. Sample weighting was employed to produce national estimates. RESULTS: Of 12,165,621 discharges, 3202 had CSVT (in-hospital prevalence 26.3 per 100,000 discharges). Male patients accounted for 57% of CSVT discharges. The median age was 8 years (interquartile range 1-16), with a U-shaped distribution with peaks in patients younger than 4 years and patients aged between 18 and 20 years. A total of 19.3% of children with CSVT had either hemorrhagic or ischemic stroke. Patients with stroke were more likely to require mechanical ventilation (odds ratio [OR] 2.7; 95% confidence interval [CI] 2.1-3.3; p < 0.001) and have higher mortality (OR 2.3; 95% CI 1.6-3.4; p < 0.001). Mechanical ventilation was necessary for 25.2% of patients with CSVT, of whom the majority were neonates and young children. The need for mechanical ventilation was associated with increased mortality (OR 16.6; 95% CI 9.9-27.9; p < 0.001). The overall mortality rate for CSVT was 4.1%, and 16.5% of patients with CSVT were discharged with home health care or to a skilled nursing facility. CONCLUSIONS: CSVT, which has a U-shaped age distribution, is an uncommon condition in children. Stroke is common in children with CSVT, and it is associated with an increased need for mechanical ventilation and increased mortality. The need for mechanical ventilation is more common in infants, and it is associated with increased mortality across all age groups.

INTRODUCTION: Cerebral venous sinus thrombosis associated with vaccine-induced immune thrombotic thrombocytopenia (CVST-VITT) is a severe disease with high mortality. There are few data on sex differences in CVST-VITT. The aim of our study was to investigate the differences in presentation, treatment, clinical course, complications, and outcome of CVST-VITT between women and men. PATIENTS AND METHODS: We used data from an ongoing international registry on CVST-VITT. VITT was diagnosed according to the Pavord criteria. We compared the characteristics of CVST-VITT in women and men. RESULTS: Of 133 patients with possible, probable, or definite CVST-VITT, 102 (77%) were women. Women were slightly younger [median age 42 (IQR 28-54) vs 45 (28-56)], presented more often with coma (26% vs 10%) and had a lower platelet count at presentation [median (IQR) 50x109/L (28-79) vs 68 (30-125)] than men. The nadir platelet count was lower in women [median (IQR) 34 (19-62) vs 53 (20-92)]. More women received endovascular treatment than men (15% vs 6%). Rates of treatment with intravenous immunoglobulins were similar (63% vs 66%), as were new venous thromboembolic events (14% vs 14%) and major bleeding complications (30% vs 20%). Rates of good functional outcome (modified Rankin Scale 0-2, 42% vs 45%) and in-hospital death (39% vs 41%) did not differ. DISCUSSION AND CONCLUSIONS: Three quarters of CVST-VITT patients in this study were women. Women were more severely affected at presentation, but clinical course and outcome did not differ between women and men. VITT-specific treatments were overall similar, but more women received endovascular treatment.

BACKGROUND: Cerebral sinovenous thrombosis (CSVT) is a rare form of pediatric stroke with significant morbidity. We determined cumulative incidence and predictors of acute seizures, remote seizures, and epilepsy after pediatric CSVT. METHODS: Retrospective analysis of 131 neonates and children with neuroimaging-confirmed CSVT enrolled between 2008 and 2020 from a single-center prospective consecutive cohort. Acute seizures occurred within 7 days of CSVT. Remote seizures occurred >7 days after CSVT. Epilepsy was defined as 2 or more remote seizures at least 24 hours apart. Survival methods determined the incidence of and risk factors for remote seizures and epilepsy. RESULTS: Acute seizures occurred in 14/33 neonates (42%) and 19/98 children (19%). Among children, hemorrhage predicted acute seizures (OR 6.6, 95% CI 1.9 to 22.4, P = 0.003). Remote seizures occurred in six neonates; five developed epilepsy. Remote seizures occurred in 14 children; 10 developed epilepsy. In neonates, 1- and 3-year epilepsy-free survival were 86% (95% CI 62% to 95%) and 66% (95% CI 32% to 87%). One- and 3-year epilepsy-free survival in children were 88% (95% CI 76% to 92%) and 84% (95% CI 59% to 86%). In multivariable analysis for children, acute seizures predicted epilepsy (HR 3.8, 95% CI 1.1-13.3, P = 0.039). In both cohorts, Pediatric Stroke Outcome Measure scores at last follow-up were worse in those with epilepsy compared to those without. CONCLUSIONS: Acute seizures occurred in approximately one quarter of our cohort and are an epilepsy risk factor in children with CSVT. Neonates and children with epilepsy had worse outcomes than those without.

BACKGROUND: Adenovirus-based COVID-19 vaccines are extensively used in low- and middle-income countries (LMICs). Remarkably, cases of cerebral venous sinus thrombosis due to vaccine-induced immune thrombotic thrombocytopenia (CVST-VITT) have rarely been reported from LMICs. AIMS: We studied the frequency, manifestations, treatment, and outcomes of CVST-VITT in LMICs. METHODS: We report data from an international registry on CVST after COVID-19 vaccination. VITT was classified according to the Pavord criteria. We compared CVST-VITT cases from LMICs to cases from high-income countries (HICs). RESULTS: Until August 2022, 228 CVST cases were reported, of which 63 were from LMICs (all middle-income countries [MICs]: Brazil, China, India, Iran, Mexico, Pakistan, Turkey). Of these 63, 32 (51%) met the VITT criteria, compared to 103 of 165 (62%) from HICs. Only 5 of the 32 (16%) CVST-VITT cases from MICs had definite VITT, mostly because anti-platelet factor 4 antibodies were often not tested. The median age was 26 (interquartile range [IQR] 20-37) versus 47 (IQR 32-58) years, and the proportion of women was 25 of 32 (78%) versus 77 of 103 (75%) in MICs versus HICs, respectively. Patients from MICs were diagnosed later than patients from HICs (1/32 [3%] vs. 65/103 [63%] diagnosed before May 2021). Clinical manifestations, including intracranial hemorrhage, were largely similar as was intravenous immunoglobulin use. In-hospital mortality was lower in MICs (7/31 [23%, 95% confidence interval (CI) 11-40]) than in HICs (44/102 [43%, 95% CI 34-53], p = 0.039). CONCLUSIONS: The number of CVST-VITT cases reported from LMICs was small despite the widespread use of adenoviral vaccines. Clinical manifestations and treatment of CVST-VITT cases were largely similar in MICs and HICs, while mortality was lower in patients from MICs.

BACKGROUND AND PURPOSE: Cerebral venous thrombosis (CVT) is a special cerebrovascular disease that accounts for around 0.5%-1.0% of all strokes and often occurs in younger adults. Intracranial hypertension is the most frequent symptom of acute CVT due to venous occlusion. This study aimed to ascertain the risk factors for intracranial hypertension after CVT and to investigate whether intracranial hypertension at diagnosis may affect patient outcomes. METHODS: We performed a retrospective cohort analysis of all patients treated for acute/subacute CVT at our department between 2018 and 2021. Logistic regression analysis was performed to identify potential risk factors associated with intracranial hypertension after CVT and clinical outcomes at the 6-month follow-up. RESULTS: A total of 293 acute/subacute CVT survivors were eligible for inclusion, with 245 patients (83.60%) experiencing concomitant intracranial hypertension at diagnosis. In the multivariable regression analysis, hereditary thrombophilia (OR 2.210, 95% CI 1.148-4.254, p = 0.018) and thrombosis location of superior sagittal sinus (SSS) and right lateral sinus (LS) (OR 4.115, 95% CI 1.880-9.010, p = 0.000) were independently associated with intracranial hypertension. 83.67% of patients with intracranial hypertension after CVT had favorable functional outcomes (mRS score, 0-2), whereas they more often had residual visual impairment (15.51% vs. 4.17%, p = 0.036) at follow-up. The risk factors for residual visual impairment were papilledema (OR 2.971, 95% CI 1.231-7.170, p = 0.015) and visual disturbances at diagnosis (OR 2.869, 95% CI 1.123-7.327, p = 0.028), thrombosis location (SSS and right LS [OR 10.811, 95% CI 4.208-27.773, p = 0.000]; SSS and left LS [OR 3.139, 95% CI 1.409-6.995, p = 0.005]), and CVT recurrence (OR 4.763, 95% CI 1.556-14.584, p = 0.006). CONCLUSIONS: Intracranial hypertension is the most common clinical symptom of acute CVT. At follow-up, patients with intracranial hypertension after CVT were more prone to develop residual visual impairment.

BACKGROUND Cerebral venous sinus thrombosis (CVST) in children is a rare disease with a complex, multifactorial etiopathogenesis. The Polish National Health Fund (NHF) Registry [Narodowy Fundusz Zdrowia (NFZ)], contains health insurance data from all 16 national provinces, or voivodeships. This study used data from the Polish NHF Registry to evaluate 52 pediatric patients who required 78 hospital admissions for CVST from 2013 to 2020. MATERIAL AND METHODS The data in the Polish NHF Registry were acquired based on the disease code I67.6 from the International Classification of Diseases, Tenth Revision (ICD-10), and the patients' age (up to 18 years old). RESULTS We identified 78 hospitalizations of 52 pediatric patients due to CVST in Poland from 2013 to 2020 (63.5% boys and 36.5% girls, mean age 9.7±5.8 years old). The mean duration of hospitalization was 10.5±11.7 days, the mean cost of hospitalization was 3273±2191 Polish zloty (PLN). The most common age subgroup was adolescents (27%). Ten percent of patients were hospitalized in a region other than their region of residence. The duration and cost of hospitalization were positively correlated with each other (r=0.512, P<0.001). The most common type of admission was an emergency (51%), and the most common discharge was referral for further outpatient treatment (50%). CONCLUSIONS Polish registry data showed that from 2013 to 2020, CVST was more commonly diagnosed in male adolescents from 15 to 18 years of age who presented as emergency hospital admissions. There were regional differences in incidence and duration of hospital stay and healthcare costs between patients.

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a known complication of posterior fossa surgery near the sigmoid and transverse sinus. The incidence and treatment of postoperative asymptomatic CVST are controversial. OBJECTIVE: To analyze incidence, risk factors, and management of asymptomatic postoperative CVST after posterior fossa tumor surgery. METHODS: In this retrospective, single-center study, we included all patients who underwent posterior fossa tumor surgery in the semisitting position between January 2013 and December 2020. All patients underwent preoperative and postoperative imaging using MRI with/without additional computed tomography angiography. We analyzed the effect of demographic and surgical data on the incidence of postoperative CVST. Furthermore, therapeutic anticoagulation or conservative treatment for postoperative CVST and the incidence of intracranial hemorrhage were investigated. RESULTS: In total, 266 patients were included. Thirty-three of 266 (12.4%) patients developed postoperative CVST. All patients were asymptomatic. Thirteen of 33 patients received therapeutic anticoagulation, and 20 patients did not. Univariate analysis showed that age ( P = .56), sex ( P = .20), American Society of Anesthesiology status ( P = .13), body mass index ( P = .60), and length of surgery ( P = .176) were not statistically correlated with postoperative CVST. Multivariate analysis revealed that meningioma ( P < .001, odds ratio 11.3, CI 95% 4.1-31.2) and vestibular schwannoma ( P = .013, odds ratio 4.4, CI 95% 1.3-16.3) are risk factors for the development of new postoperative CVST. The use of therapeutic anticoagulation to treat postoperative CVST was associated with a higher rate of intracranial hemorrhage (n = 4, P = .017). CONCLUSION: Tumor entity influences the incidence of postoperative CVST. In clinically asymptomatic patients, careful decision making is necessary whether to initiate therapeutic anticoagulation or not.

OBJECTIVE: This study aimed to assess the clinical characteristics of cerebral venous sinus thrombosis (CVT) patients with new-onset headache and to identify the risk factors for headache in this population. METHODS: We retrospectively reviewed the demographic and clinical data of 69 CVT patients recruited between September 2017 and September 2019. Patients were classified into two groups, the headache group and the non-headache group, according to the presence or absence of new-onset headache symptoms at admission. The following characteristics and parameters were measured and analyzed, including gender, age, amount of thromboembolic cerebral venous sinus(ATCVS), and other relevant indicators. RESULTS: The incidence of headache was 75% in this cohort. The proportion of female patients in the headache group was higher than that in the non-headache group. Patients in the headache group were younger than those without headache. CVT patients of headache group showed higher lymphocyte ratio (LR), blood urea nitrogen (BUN), and intracranial pressure (ICP) compared to the non-headache group, whereas mean corpuscular volume (MCV) and levels of protein (cerebrospinal fluid, CSF) and lactic dehydrogenase (LDH) in CSF were lower in headache patients. The data also revealed younger age and the increased level of chloride ion CI-(CSF) were the risk factors for the occurrence of headache in CVT patients. CONCLUSION: Age, LR, MCV, BUN levels, ICP, protein (CSF), and LDH (CSF) in patients with headache were significantly different from those in the non-headache group at admission. Younger age and a level of CI- (CSF) were risk factors for headache in CVT patients. These findings may provide guidance for clinical diagnosis and treatment of CVT.

BACKGROUND: The incidence of cerebral venous thrombosis (CVT) in children of the United States is unknown, and it is uncertain how the burden of CVT hospitalizations in children changed over the last decade. METHODS: We conducted a retrospective cohort study using the State Inpatient Database and Kid's inpatient database. All new CVT cases in children (0-19 years) in the New York 2006 to 2018 State Inpatient Database (n=705), and all cases of CVT in the entire US contained in the 2006 to 2019 Kid's inpatient database (weighted n=6115) were identified using validated International Classification of Diseases (ICDs) codes. Incident counts were combined with census data to compute incidence. Between-group differences in incidence were tested using 2-proportions Z-test, and Joinpoint regression was used to trend incidence over time. RESULTS: Across the study period, 48.2% of all incident CVT cases and 44.6% of all CVT admissions nationally were in girls. Of all incident cases, 27.2% were infants and 65.8% of these infants were neonates. Average incidence across the study period was (1.1/100 000/year, SE:0.04) but incidence in infants (6.4/100 000/year) was at least 5 times the incidence in other age groups (1-4 years: 0.7/100 000/year, 15-19 years: 1.2/100 000/year). Incidence and national burden of CVT admissions was higher in girls in adolescents 15 to 19 years, but overall burden was higher in boys in other age groups. Age- and sex-standardized CVT incidence increased by 3.8% annually (95% CI, 0.2%-7.6%), while the overall burden of admissions increased by 4.9% annually (95% CI, 3.6%-6.2%). CONCLUSIONS: CVT incidence in New York and national burden of CVT increased significantly over the last decade.
