Reconstructive surgery for multiple renal arteries

Renal artery occlusions occur in patients with severe aortic atherosclerosis, panarteritis, as well as as a result of previous operations and are severe vascular pathology. It is very difficult to restore renal blood circulation in such patients, since this often affects the areas of bifurcation or trifurcation of the renal arteries. Cases of multiple renal arteries are especially difficult. It is known that surgical treatment for occlusions consists in creating bypass anastomoses, in particular the anastomosis of the superior mesenteric artery with the renal artery using the great saphenous vein [5]. However, the formation of this anastomosis is feasible only when treating a single renal artery, while its multiplicity is observed in 15–38% of cases [1–3].
