Deep venous thrombosis after strokes in Chinese

|October 1, 1980
Summary
Deep venous thrombosis (DVT) incidence in Chinese stroke patients was 17%, lower than Western reports. This study confirms a lower occurrence of DVT in the Chinese population.
Area of Science:
- Neurology
- Vascular Medicine
- Epidemiology
Background:
- Stroke frequently causes hemiparesis or hemiplegia, increasing venous thromboembolism risk.
- Previous studies suggest lower venous thrombosis rates in Asian populations compared to Western populations.
Purpose of the Study:
- To investigate the incidence of deep venous thrombosis (DVT) in Chinese patients following stroke.
- To compare DVT rates in Chinese stroke patients with those reported in Western countries.
Main Methods:
- A cohort of 35 Chinese patients with stroke-induced hemiparesis or hemiplegia was studied.
- Deep venous thrombosis was detected using the 125I-fibrinogen leg scan method.
- Clinical assessment for pulmonary embolism was also performed.
Main Results:
- Deep venous thrombosis (DVT) was detected in 6 out of 35 patients (17% incidence).
- DVT occurred in the paralyzed leg in 5 patients and the normal leg in 1 patient.
- No clinical evidence of pulmonary embolism was observed in any patient.
Conclusions:
- The incidence of DVT in Chinese stroke patients is objectively confirmed to be low (17%).
- This finding supports previous observations of a lower prevalence of venous thrombosis in the Chinese population compared to Western populations.
- Further research may explore underlying genetic or environmental factors contributing to this difference.
