    Abstract:
    OBJECTIVE: To investigate the multiple correlation factors of deep vein thrombosis after trauma to lower extremities. METHODS: A total of 2727 patients with traumas from pelvis to ankle were admitted from August 2006 to March 2008 and detected by Color Doppler ultrasound for DVT of bilateral lower extremities before operation. Emergency internal fixation or external fixation was not used for all patients before operation. Seventeen clinical factors were examined in order to analyze their influences upon DVT occurrence after trauma. RESULTS: DVT occurred in 351 patients after trauma. The incidence of DVT in all patients was 12.9%. The analysis of logistic regression demonstrated a definite correlation with the increment of age, the length of presentation time and the gender of female. No associated injury lowered the odds ratio of DVT down to 1.484, 1.816, 0.637 and 0.671 respectively. Other clinical factors had no statistically significant correlation with DVT. CONCLUSION: Both the increment of age and the length of presentation time are risk factors for DVT after trauma to lower extremities. It is best to perform conventional ultrasound examinations in patients with these risk factors so as to timely treat a possible DVT.
