Color Doppler Sonography Surveillance for Deep Vein Thrombosis after Hip Replacement Surgery / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to validate the value of Duplex Color Doppler Ultrasonography (DDU) in post-operative deepvein thrombosis (DVT) after hip replacement surgery. MATERIALS AND METHODS: From September 1998 to June 2000, 138 cases (130 patients) were eligible for a minimal one-year follow-up.DDU was carried out between the 7th and 10th postoperative in all cases, patients wore a compressive stocking on the lower extremity. RESULTS: DVT occurred in five cases (4%), four cases occurred at 10th postoperative day and one case was occurred after one month. DVT occurred in the femoral vein in all cases. Three cases had clinical symptoms such as pain and localized edema. However, no case complained of systemic pulmonary symptoms. CONCLUSION: The incidence of DVT obtained from DDU after replacement hip surgery was very low (4%) with early mobilization and acompressive stocking. No case of DVT progressed to symptomatic pulmonary embolism. DDU was valuable for detecting DVT in the proximal thigh as a screening test.
