About this study

Official title: A Registry Study of Cerebral Venous Sinus Thrombosis in China

This study will investigate the epidemiology, risk factors, diagnostics, treatment, and the long-term prognosis of cerebral venous thrombosis in China.

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

An observational study of Cerebral Vein Thrombosis and Cerebral Venous Sinus Thrombosis, run by Capital Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Favorable clinical outcome (modified Rankin score 0-1) (time frame: Baseline to three years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05448248, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Feb 2024.
