髋关节置换术后发生缺血性脑卒中的危险因素分析

Risk factors in ischemic stroke following total hip replacement

目的探讨髋关节置换术后发生缺血性脑卒中的危险因素。方法采取回顾性病例对照研究方法,比较行髋关节置换术后并发缺血性脑卒中患者18例与同期随机142例无缺血性脑卒中事件患者(对照组)的临床资料。结果髋关节置换术后缺血性脑卒中的发病率为1 .8%。年龄、高血压、脑卒中病史、术中收缩压及舒张压的下降与对照组相比,有显著性差异(P<0 .05);而性别、心脏病史、糖尿病、高脂血症及术中的出血量与对照组相比,无显著性差异(P>0 .05)。结论年龄、高血压、术中血压的变化及术前脑卒中病史是髋关节置换术后缺血性脑卒中事件发生的重要危险因素。

ObjectiveTo investigate the risk factors in ischemic stroke following total hip replacement. MethodsThe clinical data of 18 patients who suffered ischemic stroke following total hip replacement were compared with other 142 patients without ischemic stroke following total hip replacement who were randomly selected as control. ResultsThe incidence rate of ischemic stroke following total hip replacement in our hospital was 1.8%. Age,hypertension, history of stroke,falling of systolic pressure and diastolic pressure during opereration were significantly different between patients and controls(P<0.05).There was no significantly different in sex,previous cardiac diseases, diabetes, hyperlipemia,and the bleeding in operation between patients and controls(P>0.05).ConclusionAge,hypertension, history of cerebrovascular disease,falling of systolic pressure and diastolic pressure during opereration are the important risk factors of ischemic stroke following total hip replacement.
