Abstract: Purpose The clinical results of percutaneous transluminal angioplasty (PTA) were evaluated in patients with renovascular hypertension, and the effect of PTA on blood pressure and renal function was determined. Patients and Methods Between February 1982 and December 1990, 93 hypertensive patients underwent 123 renal artery PTA procedures. Mean patient age was 43.4 years (range, 12–78 years). Average baseline blood pressure was 162/111 mm Hg (range, 140–230/95–150 mm Hg). The cause of renovascular hypertension, as determined with angi-ography, was atherosclerosis in 37 patients, fibromuscular dysplasia in 27, and mixed disease in one; 28 patients had renal transplant arterial stenosis. Results In patients with atherosclerotic renal vascular disease or fibromuscular renal artery stenosis, systolic and diastolic blood pressure decreased significantly (P < .001) at 96 months after PTA. In patients with renal transplant arterial stenosis, blood pressure also decreased significantly (P < .001) at 12 months after PTA. Technical success was achieved in 78% of patients with atherosclerosis, 92% of patients with fibromuscular dysplasia, and 76% of patients with renal transplants. Complications were seen in 4.8% and were related to renal failure and vessel dissection. Conclusion PTA is the therapy of choice in patients with renovascular hypertension due to fibromuscular dysplasia. Patients with atherosclerotic renal artery stenosis or stenosis of a renal artery in a transplanted kidney should be selected according to the anatomy of the lesion and clinical patient characteristics.
