“…In a cohort of 69 patients with dAVF, CVT was present in 39% [13]. In case reports, diagnosis of dAVF has been described prior to, simultaneously and subsequent to the diagnosis of CVT [7,[14][15][16][17]. Hence, the frequency and time correlation of dAVF among CVT patients remains unclear.…”

Background and purpose To explore the prevalence, risk factors, time correlation, characteristics and clinical outcome of dural arteriovenous fistulas (dAVFs) in a cerebral venous thrombosis (CVT) population. Methods We included patients from the International CVT Consortium registries. Diagnosis of dAVF was confirmed centrally. We assessed the prevalence and risk factors for dAVF among consecutive CVT patients and investigated its impact on clinical outcome using logistic regression analysis. We defined poor outcome as modified Rankin Scale score 3–6 at last follow‐up. Results dAVF was confirmed in 29/1218 (2.4%) consecutive CVT patients. The median (interquartile range [IQR]) follow‐up time was 8 (5–23) months. Patients with dAVF were older (median [IQR] 53 [44–61] vs. 41 [29–53] years; p < 0.001), more frequently male (69% vs. 33%; p < 0.001), more often had chronic clinical CVT onset (>30 days: 39% vs. 7%; p < 0.001) and sigmoid sinus thrombosis (86% vs. 51%; p < 0.001), and less frequently had parenchymal lesions (31% vs. 55%; p = 0.013) at baseline imaging. Clinical outcome at last follow‐up did not differ between patients with and without dAVF. Additionally, five patients were confirmed with dAVF from non‐consecutive CVT cohorts. Among all patients with CVT and dAVF, 17/34 (50%) had multiple fistulas and 23/34 (68%) had cortical venous drainage. Of 34 patients with dAVF with 36 separate CVT events, 3/36 fistulas (8%) were diagnosed prior to, 20/36 (56%) simultaneously and 13/36 after (36%, median 115 [IQR 38–337] days) diagnosis of CVT. Conclusions Dural arteriovenous fistulas occur in at least 2% of CVT patients and are associated with chronic CVT onset, older age and male sex. Most CVT‐related dAVFs are detected simultaneously or subsequently to diagnosis of CVT.

“…[11][12][13][14]41,51,52] In a recent randomized control trial, Connor and colleagues [48] evaluated 114 children with CVT treated with rivaroxaban or standard anticoagulation therapy and observed favorable clinical outcomes with low risk of recurrence and fewer bleeding complications similar to other existing literature. [41,[48][49][50][51][52] In another study, Ferro and coworkers [53] evaluated the safety and efficacy of dabigatran and warfarin in 120 patients from December 2016 to June 2018, with a follow-up of 25 weeks. This trial observed a low risk of recurrence and bleeding (about 1% and 3% in dabigatran and warfarin group, respectively), and recanalization rates were 60% and 67%, respectively, and recommended both dabigatran and warfarin safe and effective for preventing recurrent venous thrombosis in CVT.…”

Cerebral venous thrombosis is a rare cause of stroke in young mostly female adults which is frequently overlooked due to its variable clinical and radiological presentation. This review summarizes current knowledge on it risk factors, management and outcome in adults and highlights areas for future research. Females are 3 times more commonly affected and are significantly younger than males. The presenting symptoms can range from headache to loss of consciousness. However, the often-nebulous nature of symptoms can make the diagnosis challenging. Magnetic resonance imaging with venography is often the diagnostic imaging of choice. While unfractionated or low molecular-weight heparin is the mainstay of treatment, endovascular intervention with thrombolysis or thrombectomy and decompressive craniectomy may be required depending on clinical status. Nevertheless, approximately 80% of patients have a good recovery but mortality rates of −5% to 10% are not uncommon. Diagnosing cerebral venous thrombosis can be challenging but with vigilance and expert care patients have the best chance of a good clinical outcome.
