摘要
目的观察经低分子肝素(LMWH)预防的人工关节置换术后患者的下肢深静脉血栓发生率。方法对121例经低分子肝素预防的人工关节置换术患者于术前、术后进行彩色多普勒超声检查,评价下肢深静脉通畅情况。结果经LMWH预防的人工关节置换术后DVT发生率为50.4%,全髋关节置换术后DVT发生率为13.3%,全膝关节置换术后为72.4%(P<0.005),双膝关节置换术后DVT发生率高于单膝关节置换术后(P<0.05)。人工关节置换术后近端DVT发生率为3.3%,远端DVT发生率为47.1%。结论尽管采用LMWH预防,人工关节置换术后下肢DVT发生率仍然很高,术后有必要早期应用彩色多普勒超声进行监测,及时发现、治疗下肢深静脉血栓。
Objective To observe the incidence of deep vein thrombosis (DVT) after total joint arthroplasty under the treatment of low-molecular-weight heparin prophylaxis. Methods Color Doppler ultrasonography was used to detect DVT in 121 patients with prophylaxis before and after arthroplasty. Results The total incidence of DVT was 50.4% among the 121 patients, with 13.3% in total knee replacement, and 72.4% in total hip replacement. The incidence of proximal DVT was 3.3%, while the incidence of distal DVT was 47.1%. Conclusion The incidence of DVT is still high in total joint arthroplasty even treated by prophylaxis. Ultrasonography should be considered as a noninvasive, accurate, useful method in diagnosing DVT before and after arthroplasty.
