Between 1970 and 1982, 50 patients (38 male and 12 female) underwent revascularization of 51 occluded renal arteries. Ages ranged from 8 to 71 years (mean 54.6 years). Occlusion was caused by atherosclerosis in 43 patients, fibromuscular dysplasia in three, chronic dissection in two, abdominal aortic coarctation in one, and neurofibromatosis in one. Contralateral renal artery occlusive disease occurred in 22 patients. Extrarenal atherosclerosis occurred in 44 patients. Mean preoperative serum creatinine level ranged from 0.5 to 8.4 mg/dl (mean 1.9 mg/dl). No patient required preoperative dialysis. Length of the involved kidney ranged from 8.4 to 14.5 cm (mean 11.5 cm). Indication for renal revascularization was hypertension in 49 patients and preservation of renal function in one. Renal artery bypass was performed in 36 patients, renal artery endarterectomy in six, transaortic endarterectomy in five, and reimplantation of the renal artery in three. Simultaneous revascularization of the contralateral renal artery was performed in 20 patients. There were three operative deaths. At hospital dismissal, hypertension had improved in 45 of 46 patients. Follow-up periods ranged from 4 months to 12 years (mean 50.2 months). Thirty-four patients remained normotensive, five still had less hypertension, and seven became worse. These data demonstrate that revascularization of an occluded renal artery can be effective in controlling hypertension and that this effect is durable in the majority of patients.
