Characteristics of Poor Prognosis in Patients with Cerebral Venous Sinus Thrombosis: A Multicenter Retrospective Study.

Headache was the most common and protective manifestation of CVST, and disturbances in consciousness were an important indication of poor clinical prognosis. Patients with hematologic diseases also tended to have poor outcomes. No significant correlation was found between the number and location of venous sinus thromboses and clinical prognosis; however, intracranial injury involving multiple lobes was often associated with poor prognosis.
