Abstract

Deep vein thrombosis(DVT) after joint arthroplasty in tbe lower extmmity has been one of the major causes of death in postoperative complications. But, there is little information on incidence and clinical risk factors of DVT in Korea. Fifty-eight patients (sixty-two cases) who underwent TKR were included in this study for evaluation of the incidence of DVT and correlation with clinical risk factors after total knee replacement(TKR) in Korea. Venography were performed preoperatively and postoperatively, and clinical risk factors were examined. The preoperative venography was performed within seven days before the surgery, and postoperative venography seven to 14days after the surgery. There was no evidence of thrombosis in any patient preoperatively, but thrombi were observed in seven cases (11%) postoperatively. Six cases showed thrombi in the calf vein and one case showed thrombi in the femoral vein. There was no statistically significant difference in incidence rate of DVT according to clinical risk factors such as age, toumiquet time, BMI(body mass index), diastolic blood pressure, operation time and coagulation assay(platelet, PT, aPTT, Anti-thrombin III, fibrinogen).
