title: Renovascular hypertension - simultaneous aortic and renal artery reconstruction.
abstract: Despite the enormous progress that has been madein the fields of vascular surgery and intensive care, reconstructive surgery of renal arteries in the presence of arteriosclerosis of the abdominal aorta remains a serious therapeutic problem and is associated with a high rate of complications. The purpose of this study was to analyze the results of treatment of patients with renovascular hypertension and so-called difficult aorta. Surgery was carried out in 68 patients with a critically stenosed renal artery and severe arteriosclerosis of the abdominal aorta. In 53 patients an aortobifemoral prosthetic graft was implanted together with endarterectomy of the renal artery in 23 patients, an aortorenal venous graft in 23 patients and a prosthetic graft in 7 patients. In the remaining 15 patients extra-anatomic anastomoses were performed between the splenic artery and the renal artery (7 patients), hepatic artery and renal artery (6) and between the superior mesenteric and renal artery (2). Postoperatively, the hypertension was cured in 55% of patients, improved in 38% and remained unchanged in 7%. After 1 year the results were respectively 47, 36, and 17%. The patients with an aortorenal prosthetic graft demonstrated a greater tendency for hypertension to recur.
