Cutting balloon angioplasty of resistant renal artery stenosis caused by fibromuscular dysplasia.

Abstract

Balloon angioplasty is an established intervention to treat renovascular hypertension. Conventional balloon angioplasty is usually effective in cases of renovascular hypertension caused by fibromuscular dysplasia. In the present report, we describe two cases of renovascular hypertension caused by fibromuscular dysplasia in which stenotic lesions were resistant to conventional balloon angioplasty but were successfully managed by a cutting balloon. After cutting balloon angioplasty, systemic blood pressure was normalized in both patients, without the use of antihypertensive agents. Angioplasty by using a cutting balloon is a new therapeutic choice against renal artery stenosis that is resistant to dilation by a conventional balloon.
