Figure 2. Diagram illustrates the portal-enteric technique for pancreatic transplantation. Vascular reconstruction involves connecting a donor iliac arterial Y-graft, composed of the internal and external branches of the donor common iliac artery, to the donor splenic (sp) and superior mesenteric (sm) arteries. The common iliac portion of the Y-graft is then anastomosed to the recipient common or external iliac artery. Venous drainage goes into the superior mesenteric vein (S). Note the donor duodenum (D), which is oversewn at both ends, with a side-to-side anastomosis to the recipient Roux-en-Y loop.
