Abstract: 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.

Key words: total hip replacement, ischemic stroke, risk factors
