For reasons of volume, a liver graft from a living donor should come from the right lobe for adult recipients, and from the left lateral segment for pediatric recipients. For donors, postoperative mortality and morbidity rates are significantly higher for right lobectomies than for removal of the left lateral section. Although living donor liver transplantation is more technically demanding, its results are similar to those with cadaveric liver transplants in expert centers. The primary contraindications to living donations are elevated body mass index and hemostatic or thrombotic disorders.
