NCT03919305

Brief Summary

This study was aimed to reveal the clinical features,natural history of the diseases and current therapeutic situations of cerebral venous thrombosis (CVT) in China mainland. Blood samples and cerebrospinal fluid samples will be collected after recruitment to reveal the pathological mechanisms of CVT and identify the biomarkers for CVT.
