Percutaneous Transluminal Renal Angioplasty in Renovascular Hypertension

Percutaneous transluminal balloon angioplasty (PTA) of 83 renal artery lesions in 55 patients was done because of renal failure in eight patients, hypertension in 35, renal failure and hypertension in 11, and polycythemia in one patient. Early results in 38 patients with arteriosclerosis showed five (13%) were worse and 13 (34%) were unchanged. Twenty patients (53%) with arteriosclerosis were initially cured or improved; however, seven of these patients had recurrence in 4 to 48 months. Ultimately, only 13 of 38 patients with arteriosclerosis (34%) were cured or improved (mean follow-up 22 months). Nine patients with fibromuscular dysplasia required 17 dilatations of arteries (three bilateral and five repeat), resulting in eight patients (89%) who were cured or improved. Selection of patients with hypertension by medical failure while receiving three or more hypertension medications or by lateralizing renal vein renin values yielded benefit in 17 of 26 patients (65%). Five of six patients with transplant stenosis of the renal artery and hypertension were cured or improved at mean follow-up of 18 months. Overall technical results of 83 artery dilatations were as follows: good, 58 (69%); fair, 10 (12%); poor or unsatisfactory, 16 (19%); these were judged with a blinded radiologic review. No patient suffered main renal artery thrombosis. There were 16 patients with complications of dilatation (morbidity rate of 29%). Nine patients subsequently had renal artery surgery from the same day to 64 days later with good results in all patients except one.(ABSTRACT TRUNCATED AT 250 WORDS)
