Partial left lateral segment transplant from a living donor.

A shortage of liver donors for low-weight transplant recipients has prompted the development of procedures for liver-reduction, split-liver, and living related donor transplantations. For pediatric recipients weighing less than 10 kg, the left lateral segment is often still too large. We describe the procedure of monosegmental transplantation using segment II after segment III was resected in situ from a living related donor. Successful monosegmental transplantation is technically feasible and is a valid alternative to be considered for cases of size discrepancy between the recipient's volume and the donor's left lateral segment.
