The recipient splenic artery for arterialization in orthotopic liver transplantation

Abstract

Adequate hepatic arterial reconstruction is essential for successful liver transplantation. In the case of insufficient recipient hepatic arterial flow, most surgeons recommend the use of the aorta for arterialization of the graft. We report here on a technique in which the recipient splenic artery is used in such a setting. The splenic artery is dissected from its origin on a 3-to-4 cm segment and divided. The proximal segment is flipped to the right and anastomosed to the graft's celiac axis in an end-to-end fashion. This technique was used in 7 of 79 orthotopic liver transplantations (9%) because the native hepatic artery was deemed to be inadequate for anastomosis. There were no complications related to the use of this technique and no arterial thromboses. Arterialization of hepatic grafts using the recipient proximal splenic artery is a simple, safe, and efficient technique that can be recommended in the presence of an inadequate recipient hepatic arterial flow.
