Arterial reconstruction of the pancreatic allograft for transplantation.

The shortage of organs is particularly acute in whole pancreas transplantation, because the liver and pancreas often share a common arterial supply, making combined procurement of both organs difficult. A previously described technique of simultaneous whole liver and pancreas procurement depended on "classic" hepatic arterial anatomy, which is present just over half the time. We describe herein our experience with three Y-reconstructions of the splenic and superior mesenteric arteries of the pancreatic allograft using donor allograft internal and external iliac arteries. In situ Doppler ultrasound examination of the pancreatic allograft after surgery demonstrated a patent reconstruction without evidence of stenosis or turbulent flow patterns. We believe this reconstruction is a safe, alternative method to provide arterial flow to the whole donor pancreas.
