de Sousa DA, Neto LL, Arauz A, et al. - Researchers sought to evaluate, in patients with cerebral venous thrombosis (CVT) treated with standard anticoagulation, the rate of early venous recanalization, if lack of early recanalization was predictor of parenchymal brain lesion progression, and the prevalence and characteristics of persistent headache according to the recanalization grade achieved. They involved 68 patients with CVT, 30 (44%) of whom had parenchymal lesions. Early recanalization was associated with both early regression and lower risk of nonhemorrhagic lesions enlargement. Venous recanalization occurred in most CVT patients within the first 8 days of therapeutic anticoagulation and was associated with early regression of non-hemorrhagic lesions, including venous infarction. An association was found between persistent venous occlusion at day 8 and enlargement of nonhemorrhagic lesions.
