A total of 20\/48 (41.7%) patients developed asymptomatic calf vein thrombosis. One out of 20 patients required anticoagulation because of thrombus propagation. None of the subjects showed signs or symptoms of DVT or pulmonary embolism. A total of 7\/20 thrombi resolved completely at 4\u2003weeks after operation. Only old age and smoking were identified as being associated with a higher incidence of DVT. Disseminated disease, type of operation, duration of operation and postoperative complications did not appear to be risk factors for DVT.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> \u2003A high incidence of asymptomatic calf vein thrombosis occurred after colorectal surgery for malignancies in Chinese.
