Treatment of renovascular hypertension: One year results of renal angioplasty

Kidney Int (Dec) 48:1936-1945 1995

Percutaneous renal angioplasty (PTRA) was performed in 180 renal arteries in 137 patients over the period 1981-1991 in a single center in Goteborg, Sweden. 78% of patients had atherosclerotic vascular disease (AVD) and 22% had fibromuscular dysplasia (FMD). Technical success was achieved in 82% and 97% of arteries, respectively. Cure or improvement in hypertension occurred in 64% of AVD and 86% of FMD patients overall. Most patients also had improved or unchanged renal function. In patients with hypertension and renal insufficiency (GFR < 30 ml/min/ 1.73 m2 BSA), only 20% of patients had improvement in hypertension; however, 50% of such patients had improvement in GFR. Stenosis recurrence rates at one year were 15% for AVD and 7% for FMD. PTRA may be the best first approach for all but ostial lesions. (Leehey)
