Abstract

This study retrospectively reviewed the technical and clinical results of percutaneous transluminal renal artery angioplasty (PTRA) for non-atheromatous renal artery stenosis (RAS) in a Tertiary Renal Referral Centre. Forty-three patients (including 9 children) underwent 49 PTRA procedures for stenoses of 63 arteries over the period 1984-2001 (14 patients had bilateral stenosis treated during one procedure. There were 29 females and 14 males (age range 1-72 years, median 37 years). The etiology of the RAS was classical beaded FMD (medial fibroplasia) in 24, atypical or "variant FMD" with a more focal stenosis (intimal fibroplasia) in 11, neurofibromatosis type 1 (NF) in 7 and Takayasu's Arteritis in 1. Five of the NF patients had angioplasty for stenoses following vascular repair procedures. A technically good result was obtained in 34/34 arteries with "classical" RAS, 9/13 atypical arteries, 11/15 arteries of NF patients and in the one Takayasu's case. Clinical follow-up for a mean of 16 months revealed a cure rate of hypertension in classical FMD of 35% with improvement in a further 55%. In the atypical FMD cases, follow-up was obtained on 6 patients with 2 cures and the other 4 demonstrating benefit. There was a better chanc...Continue Reading
