Multicenter Registry Study Of Cerebral Venous Thrombosis In China (RETAIN-CH)

The epidemiology, risk factors, diagnosis and treatment of Cerebral Venous Thrombosis (CVT) in China are still unclear. A retrospective hospital-based study will be conducted at fifty different hospitals across 31 provinces in China. This study will use ICD-10 to search patients diagnosed with CVT between January 1, 2018 and June 15, 2022 across 31 provinces and municipalities of 104 hospitals in China. Risk factors, clinical and radiological findings, treatment and short-term outcomes will be recorded from the hospital record system. Finally, a prospective follow-up will be conducted for all of the patients enrolled above. By combining data collected from retrospective hospital records with the new follow-up, it will be possible to better understand the epidemiology, risk factors, diagnosis, treatment and the long-term prognosis of CVT in China.
