In living donor liver transplantation (LDLT), the size of the graft is a major concern for both donor and recipient safety. Small for size graft (<0.6% – 0.8%) causes graft dysfunction and other life threatening complications. Conversely, large for size grafts (>5%) may be associated with anatomical, immunological disadvantages and graft necrosis; however, their negative impact is less pronounced. In recipient, an adequate graft volume is necessary to satisfy the metabolic demands of the recipient. The residual liver volume in the donor must be sufficient for postoperative liver regeneration and metabolic needs. During graft harvesting of LDLT, it should be determined on which side of the donor liver, the middle hepatic vein should be preserved to avoid congestion of parenchyma. The congestive area in the right liver graft does not function well immediately after transplantation. Presence of fatty change in a live donor is a major concern, affecting the post-transplantation graft dysfunction. Severe steatosis of the liver graft places the recipient at risk for PNF in DDLT. Therefore, an accurate preoperative estimation of the volume should be mandatory for LDLT.
