Renovascular disease in the elderly: an analysis of 50 patients.

Fifty patients, 65 years of age or older, with renovascular disease were evaluated and treated between 1979 and 1981. Twenty-one patients were treated medically, 21 surgically and 8 with percutaneous transluminal angioplasty of the renal arteries. The age, sex, target organ involvement, initial blood pressure and serum creatinine were similar among the three groups. Sixty-six percent of the medical group demonstrated lower blood pressure. Ninety percent of the surgical group demonstrated a cure or improved blood pressure, and 43% of the patients with percutaneous transluminal angioplasty had improved blood pressure. Renal function deteriorated in 50% of the medical group, 19% of the surgical group and 25% of patients in the percutaneous transluminal angioplasty group. There was one operative death in the surgical group and one death related to percutaneous transluminal angioplasty. The data demonstrate that old age itself is not a contraindication to surgery. If hypertension is resistant to medical therapy, if the patient experiences undesirable side effects from the medications or if renal function is jeopardized, surgical therapy should be considered. More experience with percutaneous transluminal angioplasty is necessary to determine its precise role in managing atherosclerotic renal vascular disease in the elderly.
