ABSTRACT
Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.
