Aseptic cerebral venous thrombosis: Proposed prognostic scale.
Seventy-eight patients with aseptic cerebral venous thrombosis between 1966 and 1990 were reviewed in order to determine prognostic factors for this condition. Sixty-eight patients were women. The average age of the patients was 30.5 years. Fifty-two percent of patients developed the thrombosis during the postpartum or puerperal stage. The clinical manifestations that were associated with a poor prognosis were: stupor or coma, bilateral pyramidal tract signs, generalized seizures, meningeal signs, bilateral lesions on computed tomography, and hemorrhagic cerebrospinal fluid. Using these clinical features, a prognostic scale is proposed with a positive predictive value of 0.98 for a good prognosis and 0.96 for a poor prognosis.
