Angiographic findings following surgical treatment for renovascular hypertension

The authors present the postoperative angiographic appearance of the revascularized renal artery in 128 patients. The angiographic findings in four types of surgical procedures (saphenous bypass graft, dacron graft, endarterectomy, and reimplantation of the renal artery) are discussed. Postoperative angiography accurately demonstrates graft patency or occlusion.
