BACKGROUND: Cerebral venous thrombosis (CVT) is a cerebrovascular disorder that accounts for 20% of perinatal strokes. CVT incidence ranges from 0.67 to 1.12 per 100,000 newborns, while the incidence of "deep medullary vein thrombosis" (DMVT), a subtype of CVT, cannot be accurately estimated. This study aims to analyze the case history of CVT in the neonatal period, with a specific focus on DMVT. MATERIALS AND METHODS: Newborns diagnosed with CVT, with or without DMVT, between January 2002 and April 2023, were collected using the Italian Registry of Infantile Thrombosis (RITI). Cerebral MRIs were reviewed by an expert neuroradiologist following a standardized protocol. RESULTS: Forty-two newborns with CVT were identified, of which 27/42 (64%) had CVT, and the remaining 15/42 (36%) had DMVT (isolated DMVT in 9/15). Symptom onset occurred in the first week of life (median 8 days, IQR 4-14) with a male prevalence of 59%. The most common risk factors for CVT were complicated delivery (38%), prematurity (40%), congenital heart diseases (48%), and infections (40%). Seizures were the predominant presenting symptom in 52% of all cases. Hemorrhagic infarction was higher in cases with isolated DMVT (77%) compared to patients with CVT without DMVT (p = 0.013). Antithrombotic treatment was initiated in 36% of patients. Neurological impairment was observed in 48% of cases at discharge, while 18 out of 31 infants (58%) presented one or more neurological deficits at long term follow up. Conclusion: DMVT occurs in over a third of neonates with CVT. Multicentric studies are essential to establish standardized protocols for therapy, neuroimaging, and follow-up in these patients.

OBJECTIVES: To investigate the risk factors and underlying causes of pregnancy-related cerebral venous thrombosis (PCVT). METHODS: A retrospective cohort of 16 patients diagnosed with CVT during pregnancy and postpartum (within six weeks after delivery) in a comprehensive hospital in China between 2009 and 2022 were carefully reviewed, focusing on demographic, clinical, and etiological characteristics, especially underlying causes. We matched 16 PCVT patients with 64 pregnant and puerperal women without PCVT to explore risk factors and clinical susceptibility to PCVT. RESULTS: PCVT occurred commonly during the first trimester (43.75%) and the puerperium (37.5%). The frequency of anemia, thrombocytosis and thrombocytopenia during pregnancy, dehydration, and pre-pregnancy anemia was significantly higher in women with PCVT than in those without PCVT (P < 0.05). Among the 16 patients, five were diagnosed with antiphospholipid syndrome and one was diagnosed with systemic lupus erythematosus. Three patients had distinct protein S deficiency and one had protein C deficiency. Whole Exome Sequencing (WES) was performed for five patients and revealed likely pathogenic mutations associated with CVT, including heterozygous PROC c.1218G > A (p. Met406Ile), heterozygous PROS1 c.301C > T (p. Arg101Cys), composite heterozygous mutation in the F8 gene (c.144-1259C > T; c.6724G > A (p. Val2242Met)) and homozygous MTHFR c.677C > T (p. Ala222Val). CONCLUSIONS: The occurrence of anemia, thrombocytopenia and thrombocytosis during pregnancy, dehydration and pre-pregnancy anemia suggested a greater susceptibility to PCVT. For confirmed PCVT patients, autoimmune diseases, hereditary thrombophilia, and hematological disorders were common causes. Screening for potential etiologies should be paid more attention, as it has implications for treatment and long-term management.

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.

OBJECTIVES: To identify the factors associated with venous collaterals in Thai patients with cerebral venous thrombosis. MATERIALS AND METHODS: This retrospective 20-year cohort study enrolled patients diagnosed with cerebral venous thrombosis between January 2002 and December 2022. Data was collected from the electronic medical record, and venous collaterals were independently reviewed by two neuroradiologists using the Qureshi classification. Patients with and without venous collaterals were compared. Significant factors (P<0.05) in the univariate analysis were recruited into the multivariate logistic regression analysis to determine independently associated factors. RESULTS: Among 79 patients with cerebral venous thrombosis, the prevalence of venous collaterals at the initial neuroimaging was 25.3%. In the univariate analysis, patients with cerebral venous thrombosis and venous collaterals were significantly younger (37.0±13.9 years vs. 44.9±17.4 years, P = 0.048), more often had occlusion in the superior sagittal sinus (80.0% vs. 54.2%, P = 0.041), and were associated with hormonal exposure (35.0% vs. 6.8%, P = 0.002). Multivariate logistic regression analysis revealed occlusion in the superior sagittal sinus (adjusted odds ratio [aOR] 3.581; 95% confidence interval [95% CI] 1.941-13.626; P = 0.044) and hormonal exposure (aOR 7.276, 95% CI 1.606-32.966, P = 0.010) as independent factors associated with venous collaterals in cerebral venous thrombosis. CONCLUSIONS: In this cohort, the prevalence of venous collaterals was 25.3%. Occlusion in the superior sagittal sinus and hormonal exposure were independently associated with venous collaterals in patients with cerebral venous thrombosis.

BACKGROUND: Due to the rarity of cerebral venous thrombosis (CVT), performing high-quality scientific research in this field is challenging. Providing answers to unresolved research questions will improve prevention, diagnosis, and treatment, and ultimately translate to a better outcome of patients with CVT. We present an international research agenda, in which the most important research questions in the field of CVT are prioritized. AIMS: This research agenda has three distinct goals: (1) to provide inspiration and focus to research on CVT for the coming years, (2) to reinforce international collaboration, and (3) to facilitate the acquisition of research funding. SUMMARY OF REVIEW: This international research agenda is the result of a research summit organized by the International Cerebral Venous Thrombosis Consortium in Amsterdam, the Netherlands, in June 2023. The summit brought together 45 participants from 15 countries including clinical researchers from various disciplines, patients who previously suffered from CVT, and delegates from industry and non-profit funding organizations. The research agenda is categorized into six pre-specified themes: (1) epidemiology and clinical features, (2) life after CVT, (3) neuroimaging and diagnosis, (4) pathophysiology, (5) medical treatment, and (6) endovascular treatment. For each theme, we present two to four research questions, followed by a brief substantiation per question. The research questions were prioritized by the participants of the summit through consensus discussion. CONCLUSIONS: This international research agenda provides an overview of the most burning research questions on CVT. Answering these questions will advance our understanding and management of CVT, which will ultimately lead to improved outcomes for CVT patients worldwide.

OBJECTIVE: The pathogenesis of intracranial dural arteriovenous fistulas (icDAVFs) is controversial. Cerebral vein thrombosis (CVT) and venous hypertension are recognized predisposing factors. This study aimed to evaluate the incidence of association between icDAVF and CVT and describe baseline aggressiveness and clinical outcomes for icDAVFs associated with CVT. The authors also performed a literature review of studies reporting icDAVF associated with CVT. METHODS: Two hundred sixty-three consecutive patients in two university hospitals with confirmed icDAVFs were included. A double-blind imaging review was performed to determine the presence or absence of CVT close or distant to the icDAVF. Location, type (using the Cognard classification), aggressiveness of the icDAVF, clinical presentation, treatment modality, and clinical and/or angiographic outcomes at 6 months were also collected. All prior brain imaging was analyzed to determine the natural history of onset of the icDAVF. RESULTS: Among the 263 included patients, 75 (28.5%) presented with a CVT concomitant to their icDAVF. For 18 (78.3%) of 23 patients with previous brain imaging available, CVT preceding the icDAVF was proven (6.8% of the overall population). Former/active smoking (OR 2.0, 95% CI 1.079-3.682, p = 0.022) and prothrombogenic status (active inflammation or cancer/coagulation trouble) were risk factors for CVT associated with icDAVF (OR 3.135, 95% CI 1.391-7.108, p = 0.003). One hundred eighty-seven patients (71.1%) had a baseline aggressive icDAVF, not linked to the presence of a CVT (p = 0.546). Of the overall population, 11 patients (4.2%) presented with spontaneous occlusion of their icDAVF at follow-up. Seven patients (2.7%) died during the follow-up period. Intracranial DAVF + CVT was not associated with a worse prognosis (modified Rankin Scale score at 3-6 months: 0 [interquartile range {IQR} 0-1] for icDAVF + CVT vs 0 [IQR 0-0] for icDAVF alone; p = 0.055). CONCLUSIONS: This was one of the largest studies focused on the incidence of CVT associated with icDAVF. For 6.8% of the patients, a natural history of CVT leading to icDAVF was proven, corresponding to 78.3% of patients with previous imaging available. This work offers further insights into icDAVF pathophysiology, aiding in identifying high-risk CVT patients for long-term follow-up imaging. Annual imaging follow-up using noninvasive vascular imaging (CT or MR angiography) for a minimum of 3 years after the diagnosis of CVT should be considered in high-risk patients, i.e., smokers and those with prothrombogenic status.

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 AND OBJECTIVES: Recent studies suggest a bidirectional relationship of dural arteriovenous fistula (DAVF) with cerebral venous thrombosis (CVT). We aimed to compare the characteristics of patients with DAVF with or without CVT and to analyze the risk factors for the coexistence of CVT in a DAVF population. METHODS: A total of 511 adult patients with DAVF were enrolled consecutively in our hospital from February 2019 through November 2022. Demographic data, clinical manifestations, and imaging characteristics were reviewed in detail. The patients with DAVF were divided into two groups: DAVF with CVT (DAVF-CVT) group and without CVT (DAVF alone) group. Univariate logistic regression and multivariate logistic regression were used to analyze the risk factors for the coexistence of CVT and DAVF. RESULTS: CVT was found in 19.8% of patients with DAVF. In univariate analysis, compared with the DAVF-alone group, the DAVF-CVT group was more likely to have tinnitus ( P = .001), blurred vision ( P < .001), visual field loss ( P = .001), focal neurological deficits ( P = .002), seizures ( P = .008), and cognitive impairment ( P = .046) and less likely to have spinal cord/brain stem dysfunction ( P = .004). In addition, there were significant differences in age ( P = .009), sex ( P = .019), the occurrence of venous cerebral infarction ( P = .001), and DAVF location ( P < .001) between the two groups. Furthermore, multivariate analysis showed that blurred vision, venous cerebral infarction, large sinus DAVF, and multiple DAVF were risk factors for the coexistence of CVT in patients with DAVF, with the odds ratio of 2.416 (95% CI 1.267-4.606, P = .007), 6.018 (95% CI 1.289-28.100, P = .022), 5.801 (95% CI 2.494-13.496, P < .001), and 5.640 (95% CI 2.122-14.989, P = .001), respectively. CONCLUSION: CVT occurred in approximately one fifth of patients with DAVF. Blurred vision, venous cerebral infarction, large sinus DAVF, and multiple DAVF may be the risk factors for predicting the coexistence of CVT in patients with DAVF.

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.

BACKGROUND: Whether cerebral venous thrombosis (CVT) is a marker of cancer in clinical practice remains unknown. Little is known about the prognosis of cancer detected subsequent to CVT. METHODS: We used Danish nationwide registries (1996-2019) to identify patients with a first-time primary inpatient diagnosis of CVT without a history of cancer (N=811, 65% women, median age 42 years). We assessed the risk of an incident cancer diagnosis using standardized incidence ratios (SIRs). This measure contrasts the number of observed cancers among patients with CVT to the number of expected cancers where patients with CVT have the same cancer risk as the general population. We used Kaplan-Meier survival analysis and Cox regression to compare the survival of patients with both cancer and CVT with the survival of patients with cancer but without CVT, matched on cancer site, sex, age, and year of cancer diagnosis. RESULTS: Observing 43 incident cancer cases during follow-up, the overall SIR was unity (SIR, 1.04 [95% CI, 0.75-1.40]). However, the risk was ≈7-fold the expected level in the first 3 months following CVT diagnosis (SIR, 7.00 [95% CI, 3.02-13.80]) and ≈2-fold the expected level from 3 to 12 months following CVT diagnosis (SIR, 2.21 [95% CI, 0.89-4.56]). By 12 months following CVT diagnosis, the risk resembled the expected level (SIR, 0.76 [95% CI, 0.50-1.09]). Survival among cancer patients with prior CVT versus cancer patients without prior CVT was 91% versus 87% after 6 months and 65% versus 70% after 5 years. The adjusted hazard ratio of death was 0.78 (95% CI, 0.44-1.38). CONCLUSIONS: Patients with CVT were not at overall increased risk of a cancer diagnosis, except in the first 3 months after diagnosis during which period the risk was elevated ≈7-fold. The estimate from this early period, however, was based on only a few cancer diagnoses. Unlike other forms of venous thrombosis, a prior diagnosis of CVT did not negatively impact cancer survival.

BACKGROUND: Seizures are common in cerebral venous thrombosis (CVT). The occurrence of acute symptomatic seizures (ASS) has implications for patients' management, with some patients developing unprovoked late seizures (ULS). We aimed to determine risk factors for the development of ASS, ULS, and seizure recurrence (SR) in patients with CVT. METHODS: We performed an observational retrospective analysis of 141 patients with CVT. We recorded the occurrence of seizures, their time relation to the first-symptom onset, and their relation with demographic, clinical, CVT risk factors, and radiological findings. Seizure recurrence (total recurrency, recurrent ASS, and recurrent LS), potential risk factors, and the use of antiepileptic drugs (AED) were also analysed. RESULTS: Thirty-two (22.7%) patients developed seizures: 23 (16.3%) were ASS and 9 (6.3%) ULS. After multivariable logistic regression, seizure patients had more focal deficits (p = 0.033), parenchymal lesion (p < 0.001), sagittal sinus thrombosis (p = 0.007). In ASS, more frequent focal deficits (p = 0.001), encephalopathy (p = 0.001), mutation in V Leiden factor (p = 0.029), and parenchymal brain lesions (p < 0.001) were observed. ULS patients were younger (p = 0.049) and took more hormonal contraceptives (p = 0.047). Thirteen (9.2%) patients suffered SR (2 recurrent ASS only, 2 recurrent LS only, 2 both acute and recurrent LS), which was more frequent in patients with focal deficits (p = 0.013), infarct with haemorrhagic transformation (p = 0.002), or previous ASS (p = 0.001). CONCLUSION: The occurrence of seizures in patients with CVT is related to focal deficits, structural parenchymal lesions, and superior sagittal sinus thrombosis. SR is frequent, even in patients under AED. This shows the important impact that seizures have on CVT and its long-term management.

BACKGROUND: A venous pattern of infarction on neuroimaging is used as a clue to undiagnosed cerebral venous thrombosis (CVT); prevention of venous infarction is a goal of CVT management; and venous infarction is a factor used for clinical prognostication. Despite widespread use of the term venous infarct, the prevalence of true venous infarction is unclear. Our primary aim was to determine the prevalence of venous infarction in patients with CVT. We also measured the prevalence of diffusion abnormality without infarction, vasogenic edema, and intracranial hemorrhage. METHODS: Single-center, retrospective cohort study using a registry of 110 consecutive patients admitted to hospital with cerebral venous thrombosis between 2004 and 2014. Inclusion criteria were brain magnetic resonance imaging (MRI) and contrast-enhanced venography at presentation, and repeat brain MRI ≥1 month later. Exclusion criteria were dural arteriovenous fistula, arteriovenous malformation, cavernous sinus thrombosis, or previous neurosurgical procedure. Main outcome was proportion of patients with venous infarction (irreversible ischemic injury) diagnosed using diffusion-weighted MRI at presentation, confirmed using T2-weighted fluid-attenuated inversion recovery MRI ≥1 month later, and reported with 95% CI using the Wilson score interval method. We also report the prevalence of transient diffusion MRI abnormality without infarction, vasogenic edema, and intracranial hemorrhage. RESULTS: Seventy-three patients met the inclusion criteria, and after exclusions, the final study population was 59 patients with median age 41 years (interquartile range, 32-57). Venous infarction occurred in 12% (7/59 [95% CI, 6%-23%]) of patients, and final infarct volume was >1 mL in only 5.1% (3/59) of patients. An additional 8% (5/59 [95% CI, 4%-18%]) of patients had a transient diffusion MRI abnormality without infarction. Prevalence of cerebral vasogenic edema and intracranial hemorrhage were 66% (39/59 [95% CI, 53%-77%]) and 54% (32/59 [95% CI, 41%-66%]), respectively. CONCLUSIONS: In patients with CVT, venous infarction is uncommon and venous infarcts are typically very small. Vasogenic edema and hemorrhage are more common consequences of CVT.

Background: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke in young adults. We aimed to determine the impact of age, gender and risk factors (including sex-specific) on CVT onset. Methods: We used data from the BEAST (Biorepository to Establish the Aetiology of Sinovenous Thrombosis), a multicentre multinational prospective observational study on CVT. Composite factors analysis (CFA) was performed to determine the impact on the age of CVT onset in males and females. Results: A total of 1309 CVT patients (75.3% females) aged ⩾18 years were recruited. The overall median (IQR-interquartile range) age for males and females was 46 (35-58) years and 37 (28-47) years (p < 0.001), respectively. However, the presence of antibiotic-requiring sepsis (p = 0.03, 95% CI 27-47 years) among males and gender-specific risk factors like pregnancy (p < 0.001, 95% CI 29-34 years), puerperium (p < 0.001, 95% CI 26-34 years) and oral contraceptive use (p < 0.001, 95% CI 33-36 years) were significantly associated with earlier onset of CVT among females. CFA demonstrated a significantly earlier onset of CVT in females, ~12 years younger, in those with multiple (⩾1) compared to '0' risk factors (p < 0.001, 95% CI 32-35 years). Conclusions: Women suffer CVT 9 years earlier in comparison to men. Female patients with multiple (⩾1) risk factors suffer CVT ~12 years earlier compared to those with no identifiable risk factors.

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.

OBJECTIVE: Data regarding diagnosis, management, and prognosis of patients with cerebral venous thrombosis (CVT) from high altitude are limited. The aim of the present study is to identify the clinical features, risk factors, and outcomes of cerebral venous thrombosis (CVT) in Tibet. METHODS: We retrospectively included patients with a diagnosis of CVT consecutively admitted to Tibet Autonomous Region People's Hospital between July 2015, and September 2022. The risk factors, clinical and radiological presentations, treatment and outcomes were analyzed. RESULTS: A total of 38 patients with CVT were included in this study. The median age was 31 years, and females accounted for 63.2%. Patients of Tibetan nationality accounted for 71.1% (n = 27) and the median altitude of residence in Tibet was 3800 m (3657, 4054). Headache was the most common symptom (92.1%). The most common risk factors of CVT were infection in the past 4 weeks (34.2%) and pregnancy or puerperium (23.7%). Lateral sinus (transverse and/or sigmoid sinus) (68.4%) and superior sagittal sinus (55.3%) were the most commonly involved. The D-dimer increased in 31 patients (81.6%). All three patients who died in hospital and during follow-up had risk factor of recent infection. Favorable outcome at follow-up with a median length of 454 days (189, 1059) was observed in 85.3% of patients. CONCLUSIONS: CVT at high altitude is more common in young patients and women, with various clinical manifestations and risk factors. Recent infection is the most common risk factor and may increase the mortality of CVT at high altitude. The long-term prognosis of CVT at high altitude is favorable.

AIMS: Cerebral venous thrombosis (CVT) is a major cause of stroke in young and middle-aged adults. This study aimed to evaluate the prevalence of post-CVT employability decline and identify factors associated with unemployment. METHODS: We identified patients first diagnosed with acute/subacute CVT at Xuanwu Hospital, Capital Medical University (January 2018 to June 2021) and invited all survivors to a clinical 6-months follow-up visit after onset. Baseline data were collected from all patients at admission. A modified Rankin Scale (mRS) and employment status were used to assess functional outcomes. Multivariate logistic regression was used to identify independent factors associated with unemployment. RESULTS: A total of 303 CVT patients were eligible for this study, 131 (42.23%) patients could not return to work 6-month after discharge. After adjusting for age and sex in multivariate analysis, motor deficits, aphasia, mental disorders, CVT recurrence, National Institutes of Health Stroke Scale (NIHSS) score at admission, and mRS 0-2 at 6-month follow-up were independently associated with employment after CVT. Among 263 patients whose mRS showed a favorable outcome, 102 patients were unable to return to their previous work and the risk factors for impaired ability to return to work were aphasia and CVT recurrence. CONCLUSIONS: Impaired employability after CVT was associated with motor deficits, aphasia, mental status disorders, and NIHSS score at admission. Even if they recover from CVT without physical disability, patients with a good functional prognosis have a higher risk of employment failure due to their higher rates of aphasia and CVT recurrence.

BACKGROUND: Studying the baseline incidence of cerebral venous thrombosis (CVT) prior to COVID-19 and the limitations of how this has been previously reported in the literature will help improve understanding of this disease and how risks may have changed in the post-COVID era. METHODS: We examined CVT incidence using linked administrative data in British Columbia, Canada (population 5.2 million). To contextualize our findings, we also examined CVT incidence in the published literature and searched MEDLINE and EMBASE for article titles and abstracts up to Nov 2, 2021 on CVT incidence in adults. We performed abstract screening and full-text review prior to data extraction and explored associations between CVT incidence and year of study, geographic location, and study quality with meta-analyses and meta-regression. A random-effects restricted maximum likelihood model was used. Publication bias was assessed using the Egger tests and using visual inspection of the funnel plot for symmetry. RESULTS: There were 554 unique CVT cases (mean age 50.9 years, 55.4% women) in British Columbia from 2000 to 2017; overall annual incidence was 8.7 (95%CI' 8.0-9.4) per million. Incidence increased over time in men across the entire study period, and from 2011 to 2017 in women. We identified 22 other studies on CVT incidence before 2020 (21/23 total studies included in meta-analysis). Annual incidence overall was 12.1 (95% CI' 9.9-14.3) per million with significant between-study heterogeneity (I2 98.8%, Qp-value<0.001). There were no significant associations on meta-regression between incidence and study year, study quality score, or gross national income per capita of the study country. Visual inspection of the funnel plot and a significant Egger test (z=2.8, P<0.01) suggested possible publication bias. CONCLUSIONS: Incidence of CVT in Canadian data increased over time but remained lower than in other population-based studies. Significant heterogeneity exists in the literature, which may be subject to publication bias.

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.

BACKGROUND: Headache is the most frequent symptom of cerebral venous thrombosis (CVT) but there is limited information about the frequency and phenotype of headache, weeks to months after cerebral venous thrombosis (post-cerebral venous thrombosis headache, PCH). OBJECTIVE: To assess the frequency, characteristics and predictors of PCH. METHODS: In this cross-sectional study, the frequency and characteristics of PCH were assessed in cerebral venous thrombosis survivors. Patients were interviewed between six months and five years after the cerebral venous thrombosis diagnosis. Clinical and imaging characteristics at the time of cerebral venous thrombosis diagnosis, as well as history of headache prior to cerebral venous thrombosis were compared in subjects with (GroupPCH) and without PCH (Groupcontrol). RESULTS: Subjects (n = 100; 82% women) were assessed, on average, at 1.1 ± 1.6 years of follow-up. PCH was present in 59% of the patients, phenotypes of tension-type-like headache were present in 31/59 (52.6%) and of migraine-like headache in 16/59 (27.1%). History of primary headache prior to cerebral venous thrombosis was significantly more common (OR: 6.4; 95% CI: 1.7-36.3) in GroupPCH (33.9%) than in Groupcontrol (7.3%). CONCLUSION: PCH was present in more than half of the patients. History of prior headache may be a risk factor for PCH. Prospective studies are required to confirm these findings and determine mechanisms, as well as interventions for prevention and treatment of PCH.
