Abstract
OBJECTIVE: To investigate the risk factors and clinical characteristics of deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE). METHOD: The clinical manifestations and risk factors in 388 patients with DVT were retrospectively studied. RESULTS: The ratio of DVT cases in hospitalized patients had a trend of increasing in recent years. 80.4% of the patients with DVT had risk factors. The most common risk factors were age over 40 years old (88.9%), heart disease (43.0%), hypertension (35.1%), long term immobilization (21.1%), and infection (20.1%). The most common clinical presentations of DVT were swelling (66.2%) and pain (40.5%) of the affected extremity. Calf swelling by more than or equal to 1 cm compared with the asymptomatic leg was found in 87.2% patients. The site of DVT was more common in left extremities and proximal veins. PTE was found in 34.5% of the DVT cases and 74.6% of them were diagnosed prior to DVT. The ratio of PTE caused by DVT didn't show significant difference between left and right legs, neither between proximal and distal veins. CONCLUSIONS: The ratio of DVT cases in hospitalized patients was increasing. Most patients with DVT had risk factors. DVT was usually asymptomatic before PTE was complicated.
