髋关节置换术后脑梗死的危险因素分析

目的 探讨髋关节置换术后脑梗死发生的独立危险因素,为髋关节术后预防脑梗死提供理论依据.方法 回顾分析2003年1月至2008年9月行髋关节置换资料完整患者571例,术后并发脑梗死患者23例.对脑梗死患者的危险因素进行单因素和多因素相关分析.结果 单因素分析髋关节置换术后脑梗死危险因素主要为年龄(OR=1.075,95% CI:1.031～1.122,P=0.001)和股骨颈骨折(OR=0.673,95% CI:0.126～0.732,P=0.008).多因素分析髋关节置换术后脑梗死患者危险因素为年龄(OR=1.054,95% CI:1.005～1.105,P=O.029).结论 高龄(＞70岁)和股骨颈骨折为髋关节置换术后脑梗死的独立危险因素.

Analysis of risk factors for cerebral infarction after hip arthroplasty

Objective To investigate the independent risk factors for cerebral infarction so as to provide a theoretical basis for the prevention of cerebral infarction after total hip arthroplasty.Methods A retrospective analysis of 571 patients for hip arthroplasty was conducted from January 2003 to September 2008.Twenty-three patients were found with cerebral infarction postoperatively.Single-factor and multi-factor correlation analyses were tested for the patients with cerebral infarction after hip arthroplasty.Results The single-factor analysis for hip arthroplasty revealed that age(P=0.001)and femoral neck fracture(P=0.008)were the main factors for cerebral infarction.Furthermore,age was considered a risk factor for cerebral infarction after hip arthroplasty in multi-factor analysis(P=0.029,OR=1.054,95% CI:1.005-1.105).Conclusion Advanced age(＞70 yr)and femoral neck fracture are the main independent risk factors for cerebral infarction after hip arthroplasty.
