Recipient Surgery in Living Donor Liver Transplant
摘要
This chapter describes how to carry out recipient surgery safely with minimal blood loss in living donor liver transplant. Broadly, the recipient surgery is divided into liver explantation, temporary portocaval shunt creation, harvesting the explant liver’s portal vein and umbilical vein, bench work which includes reconstruction of the anterior sector veins of the partial liver graft, and liver graft implantation. Liver explantation is explained in the sequence of operating room requirements, preoperative preparation, incision, left lobe mobilization, right lobe mobilization, retro-hepatic dissection, phrenocaval dissociation, porta dissection, porta division, and explantation. This chapter also briefly explains the need for temporary portocaval shunt creation. Benchwork involves the reconstruction of anterior sector veins and unification of multiple portal veins to create a new middle hepatic vein and single portal inflow, respectively, using either a portal vein graft harvested from the recipient liver or cryopreserved cadaveric vein grafts or synthetic grafts. Implantation involves connecting the graft’s hepatic veins and portal vein to the recipient’s inferior vena cava and main portal veins. The graft is then given blood flow again through the portal vein (reperfusion). Post-reperfusion, graft hepatic artery is anastomosed to the appropriate recipient hepatic artery. The intraoperative Doppler ultrasound is done to ensure the patency of the anastomosed vessels, followed by anastomosis of the graft bile duct with the recipient bile duct.
