全髋关节置换术后深静脉血栓形成

Prevention and treatment of deep venous thrombosis after replacement of total hip

目的 探讨全髋关节置换术后下肢深静脉血栓形成(DVT)的发生情况及预防治疗措施。方法 对220例(244髋)全髋关节置换患者围手术期皮下注射低分子肝素来预防治疗下肢深静脉血栓形成。术后第7天行彩色多普勒超声检查。结果 58例发生下肢深静脉血栓,其中远端血栓33例,近端血栓14例,全静脉血栓11例。DVT发生率26.4％,未发生1例肺栓塞。结论 围手术期低分子肝素应用可降低全髋关节置换术后DVT发生率,且安全可靠。

Objective To explore the incidence and prophylactic treatment of lower extremity deep venous thrombosis( DVT) after total hip replacement Methods 220 patients (244 hips) were given low-molecular-weight heparin for prevention of deep venous thrombosis of lower extremity after total hip replacement. All the patients were examined with colour doppler ultrasonograhy at the 7th day after operation. Results 58 cases had developed acute postoperative deep venous thrombosis of lower extremity,of them,33 occurred in the distal end, 14 in the proximal end and 11 in the whole venous course. The rate of DVT occurrence was 26.4 % , no pulmonary embolism was found. Conclusion Utilization of low-molecular-weight heparin on peri-operative period is safe for reducing the incidence of DVT following total hip replacement.
