人工关节置换术后下肢深静脉血栓形成

Incidence of Deep Venous Thrombosis After Total Joint Arthroplasty

目的了解人工关节置换术后深静脉血栓的发生情况。方法５１例未行预防性抗凝治疗的人工关节置换患者于术后３～１３天行双侧上行性静脉造影，分析调查术后深静脉血栓的发病情况。结果人工关节置换术后深静脉血栓的总发生率为４７．１％，全髋关节置换术后深静脉血栓的发生率为４０．０％，全膝关节置换术后深静脉血栓的发生率为５３．８％。未见症状性肺栓塞患者。结论本组统计人工关节置换术后深静脉血栓的发生率和国外报道接近，这一结果应该引起人工关节外科医师的高度重视，并应针对存在高危因素的患者酌情给予适当的预防性治疗。

Objective To determine the incidence of deep venous thrombosis after total joint arthro-plasty. Methods Fifty-one patients had bilateral ascending venography between 3rd and 13th day after totaljoint replacement. Results The total incidence of deep venous thrombosis was 47. 1% among 51 patients whohad adequate venography, 40. 0% occurred in total hip replacement and 53. 8% in total knee replacement. Nosymptomatic pulmonary embolism was found. Conclusion The results indicate deep venous thrombosis altertotal joint arthroplasty is similar to that reported in the foreign literature. This suggests that prophylactic treat-ment is reasonable in patients with high risk of deep veinous thrombosis.[
