Percutaneous transluminal angioplasty of the renal arteries: intravenous digital subtraction angiography for follow-up.
A group of 50 consecutive patients who had undergone successful renal angioplasty two or more years previously was studied by video digital subtraction angiography (DSA). Thirty additional patients were studied by both DSA and conventional catheter arteriography. Among the 30 patients, DSA findings agreed with the arteriographic findings in 87% of the examinations: 92% of the postangioplasty patients had satisfactory DSA examinations. Using DSA two years after angioplasty, we were able to determine a restenosis rate of 22.5% among patients with atherosclerosis and of 0% among patients who had fibromuscular disease. DSA provides a useful method to follow-up renal angioplasty, and it is well accepted by patients.
