title: Renal revascularization in patients with total occlusion of the renal artery.
abstract: A total of 15 patients with renovascular hypertension underwent revascularization of totally occluded renal arteries. Preoperative clinical assessments suggesting renal salvageability include urographic visualization of the involved kidney, renal length greater than 9 cm., filling of the distal renal arterial tree on angiography and elevated renal vein renin levels. Postoperatively, hypertension was cured or improved in 14 patients and there was 1 failure. Over-all renal function improved in 9 of 10 patients with preoperative azotemia and stabilized in the remaining 5 patients. Revascularization can be done successfully in properly selected patients with complete renal artery occlusion, with control of hypertension and reversal of renal failure.
