Aortorenal reimplantation in treatment of renovascular hypertension.

From 1964 to 1977, 33 patients underwent aortorenal reimplantation as surgical treatment for renovascular hypertension. Over-all results were 13 patients cured (39 per cent), 15 patients improved (46 per cent), and there were 5 failures (15 per cent). The results were equally satisfactory in patients with atherosclerotic or fibrous renal artery disease. Postoperative arterial stenosis or occlusion occurred in 5 patients (15 per cent). Aortorenal reimplantation is an effective method of renal revascularization in properly selected patients, and long-term results are comparable with those of aortorenal bypass.
