Cerebral Venous Thrombosis Cohort Study in China Mainland

Clinicaltrials.gov identifier NCT03919305

Recruitment Status Not yet recruiting

First Posted April 18, 2019

Last update posted April 18, 2019

Study Description

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.

  • Condition or Disease:Cerebral Venous Sinus Thrombosis
    Deep Cerebral Vein Thrombosis
    Cortical Vein Thrombosis
  • Intervention/Treatment:
  • Phase: N/A
Detailed Description

cerebral venous thrombosis (CVT) is caused by a clot in the cerebral vein, which resulted in an obstruction of the blood outflow. CVT mainly includes cerebral venous sinus thrombosis, deep cerebral vein thrombosis and cortical vein thrombosis. However, the epidemiological features of CVT in China mainland remained obscure. This study was aimed to establish a multicenter cohort recruiting patients with CVT across 31 provinces and municipalities in China mainland. Clinical features,natural history of the diseases and current therapeutic situations will be analyzed to reveal the epidemiological features of CVT. Blood samples and cerebrospinal fluid samples will be collected after recruitment to reveal the pathological mechanisms of CVT and identify the biomarkers for CVT. Patients will be followed-up at 1, 3, 6, 12 months from baseline to evaluate the clinical prognosis and therapeutic outcomes.
