Digital subtraction angiography of the renal arteries. Prospective comparison with conventional arteriography.
Intravenous digital subtraction angiography (IV-DSA) of the aorta and renal arteries was compared with conventional arteriography of 40 patients with 92 renal arteries. Inadequate visualization of the vessel occurred in six renal arteries (6.5%). In arteries adequately imaged, for the evaluation of renal artery stenosis, the sensitivity of IV-DSA was 87.5% (28/32), the specificity 100% (54/54), and the accuracy 95.3% (82/86). Overall, accurate IV-DSA was obtained in 89.1% (82/92) of renal arteries and 85% (34/40) of the patients. IV-DSA is an accurate screening procedure for renal artery stenosis.
