Reconstruction of double hepatic arterial and portal venous branches for right‐lobe living donor liver transplantation

Reconstruction of double hepatic arterial and portal venous branches for right‐lobe living donor... Double hepatic arterial and portal venous branches are common anatomic variations of the isolated right hepatic lobe. Reconstruction of these vessels during transplantation can be challenging because of their small caliber, close proximity to other hilar structures, and abnormal alignment with the native vasculature. Practical techniques for the creation of these anastomoses would simplify the recipient surgery and might minimize the incidence of vascular complications. Alternative methods for management of these structures are summarized. The recipient's proper hepatic artery and its bifurcation are resected for use as an arterial Y‐type graft. The donor arteries are individually anastomosed at the bifurcation of the recipient's hepatic artery at the back table. The free end of the Y graft is then replaced at the origin of the gastroduodenal artery using standard branch‐patch technique. Reconstruction of a second donor portal branch is similarly facilitated by ex situ placement of a Y‐type vascular conduit derived from the recipient's portal vein. Surgical management of these vessels and reconstruction of other hilar structures are noticeably less cumbersome. There have been no short‐term vascular complications. The use of autologous vascular conduits with ex situ reconstruction facilitates management of double donor arterial and portal venous branches. The incidence of complications attributable to these methods is expected to be low. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Liver Transplantation Wiley

Abstract

Double hepatic arterial and portal venous branches are common anatomic variations of the isolated right hepatic lobe. Reconstruction of these vessels during transplantation can be challenging because of their small caliber, close proximity to other hilar structures, and abnormal alignment with the native vasculature. Practical techniques for the creation of these anastomoses would simplify the recipient surgery and might minimize the incidence of vascular complications. Alternative methods for management of these structures are summarized. The recipient's proper hepatic artery and its bifurcation are resected for use as an arterial Y‐type graft. The donor arteries are individually anastomosed at the bifurcation of the recipient's hepatic artery at the back table. The free end of the Y graft is then replaced at the origin of the gastroduodenal artery using standard branch‐patch technique. Reconstruction of a second donor portal branch is similarly facilitated by ex situ placement of a Y‐type vascular conduit derived from the recipient's portal vein. Surgical management of these vessels and reconstruction of other hilar structures are noticeably less cumbersome. There have been no short‐term vascular complications. The use of autologous vascular conduits with ex situ reconstruction facilitates management of double donor arterial and portal venous branches. The incidence of complications attributable to these methods is expected to be low.
