Early experiences with LDLT in adult patients were achieved by using the left lobe to keep a high level of safety for the donors. Approximately 20% of the evaluated donors are suitable to donate the right liver for LDLT, depending mainly on the critical remnant liver volume. On special occasions, the volume of liver graft is insufficient for adult recipients even with the use of the right lobe. As an alternative solution, right and left lateral lobe grafts from two donors have been employed. But the right lobectomy in the donor is not always safe, mainly depending on the volume of the remaining left lobe. The remnant liver volume should not be less than 30% of the total liver volume of the donor to maintain donor security. Even though a donor\'s right lobe is suitable in size as a graft for an adult recipient, the remaining left lobe may be too small with regard to the donor\'s own safety. To solve this problem, a second donor has to be found with which to perform dual graft liver transplantation, in which one graft from each of two donors is implanted into one recipient.
