Dual-Graft Liver Transplantation
Donor safety and small-for-size liver graft (SFSG) have been two critical issues in adult living donor liver transplantation (LDLT). In order to expand adult LDLT and overcome SFSG, right-lobe (RL) grafts have been utilized widely. However, the risk to the donor increases with the extent of donor hepatectomy. In potential donors demonstrating RL to left lobe (LL) volume disproportion, such as those with a RL greater than 70% of the total liver volume on preoperative volumetric CT scans, donation of the RL should be contraindicated for donor safety. Dual LL or left-lateral segment (LLS) transplantation is an alternative option to avoid both SFSG by an LL graft transplantation alone and the higher donor risks associated with a right lobectomy.
