Diagnostic Value of Captopril Renography in Identification of Renal Artery Stenosis

Objective:To evaluate the value of captopril renography in identification of renal artery stenosis in Aortoarteritis. Methods:One hundred and one patients with Aortoarteritis undergoing captopril renography were retrospectively analyzed.All patients also received renal artery angiography within 2 weeks of captopril renography. Results:Among the patients,there were 25 males and 85 females.The mean age was 30.2±10.7 years old.Seventy-seven patients had angiographic renal artery stenosis.Of them,40 had bilateral renal artery stenosis and 37 had unilateral renal artery stenosis.The sensitivity,specificity and accuracy of captopril renography was 94.8%,90.9 % and 93.6% for diagnosing renal artery stenosis,and 88.9%,91.3% and 90.0% for the number of diseased vessels. Conclusion:Captopril renography is a safe and accurate method for detection of renal artery stenosis in patients with Aortoar- teritis.
