Percutaneous transluminal angioplasty in renovascular hypertension.

The results of percutaneous transluminal angioplasty of renal arteries (PTA) were evaluated in 43 patients followed up for 2-39 months (mean: 14 months). The benefit of PTA was higher (82%) in hypertensives with arterial fibrodysplasia (n = 11) than in atherosclerotic vascular lesions (53%, n = 19). Of 15 patients with reduced renal function before PTA, the glomerular filtration rate rose in seven.
