    Abstract:
    In this study we report our experience in 74 patients with hypertension and renal artery stenosis (42 with atherosclerotic stenosis, 32 with fibromuscular dysplasia) who were followed-up for a mean observation period of 21.7 months after percutaneous transluminal angioplasty (PTA). Stenosis was unilateral in 45 cases, bilateral in 16 and located in the renal artery of a solitary functioning kidney in 13 cases. Ostial involvement was observed in 26 cases. A total of 24 patients showed impaired renal function before PTA. Overall results for BP control were 8 cures (13%), 29 improvements (48%) and 24 (39%) who remained unchanged. Five of the 24 patients (21%) with impaired renal function showed improvement with a decrease in serum creatinine levels of more than 30%. Complications of PTA were rare, being limited to two haematomas at the puncture site which resolved spontaneously. These results emphasize that PTA, an easily repeatable procedure of relatively low risk, short hospital stay and low cost, is a first choice technique in the management of renovascular hypertension.
