Percutaneous transluminal angioplasty: the treatment of choice for renovascular hypertension due to fibromuscular dysplasia.

Abstract
Renal artery strnoses (23) in 21 hypertensive patients, caused by fibromuscular dysplasia, were treated with percutaneous transluminal angioplasty (PTA). Follow-up over a period of 1-30 mo., including angiography, renal vein renin assay and radionuclide flow studies, was performed in 8 patients, each with 1 stenosis. Dilatation was initially successful in all cases and was successfully repeated in 1 case. The mean systolic pressure decreased by 61.81 mm Hg and the mean diastolic pressure by 36.28 mm Hg in response to treatment. Thirteen patients were cured, 8 were felt to have better control of blood pressure on medication and there were no failures. PTA is a clinically effective method of treating renovascular hypertension due to fibromuscular dysplasia.
