Abstract:
Objective To discuss the different clinical features and prognosis of single cerebral venous thrombosis (CVT) and multiple CVT. Methods The site and the number of vein and thrombosed sinuses of 136 patients with CVT were summarized. The patients were divided into 2 groups according to the numbers of thrombosed sinuses. The clinical features and outcome of the patients with single CVT were analyzed in comparison with those with multiple CVT by univariate analysis. Results In 44 patients (32.4%), only 1 cerebral sinus was involved. In 92 patients (67.6%), 2 or more cerebral veins and sinuses were involved (2 sinuses in 45, 3 sinuses in 35, 4 sinuses in 9, 5 sinuses in 3). The lateral sinus and the sigmoid sinus were the most frequent thrombosed sinuses which were found in 86.8% of patients; the followings were superior sagittal sinus (58.1%), straight sinus (18.4%) , deep venous system (7.4%), and cortical veins (2.9%). Mean ages were significantly older but the short-term prognosis was better in the group of patients with single CVT in comparison with those in the group of patients with multiple CVT. The patients with multiple CVT also presented more serious intracranial hypertension, more frequent parenchymal lesions and systematic thrombotic events than those with single CVT (P＜0.05). Conclusion In most CVT patients, 2 or more veins and sinuses are involved and thromboses most commonly implicate the lateral sinus and the superior sagittal sinus. Patients with multiple CVT usually present higher intracranial pressure, more serious clinical course, worse outcome and higher incidence of systematic venous thrombotic events in comparison with patients with single CVT. And the multiple sinus thrombosis is more likely to cause venous infarctions and intracranial hemorrhage than the single one.
