Simplified splanchnic artery revascularization using extra-anatomic bypass grafts: a report of ten cases.

Revascularization of the superior mesenteric artery or renal artery is frequently complicated by concomitant atherosclerotic disease in the adjacent aorta. In ten patients, extra-anatomic saphenous vein bypass grafts to the splanchnic vessels were constructed and inflow was obtained from the external iliac artery. All patients recovered without complication and have had functioning grafts on follow-up arteriography. This extra-anatomic bypass provides a simple method for splanchnic artery revascularization.
