What is the long-term prognosis of cerebral vein and dural sinus thrombosis?
The long-term prognosis of cerebral vein and dural sinus thrombosis is largely determined by the presence of underlying risk factors. According to the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT), the long-term prognosis was found to be worse for patients with underlying risk factors such as hypertension, diabetes, and hypercoagulability. Additionally, the Cerebral Venous Thrombosis Portuguese Collaborative Study Group (Venoport) reported that the long-term prognosis of patients with cerebral vein and dural sinus thrombosis was not significantly affected by age, sex, or the presence of symptoms. Martinelli et al. also conducted a long-term evaluation of the risk of recurrence after cerebral sinus-venous thrombosis and concluded that patients with cerebral vein and dural sinus thrombosis have a good long-term prognosis.
