Monosegment Liver Allografts for Liver Transplantation in Infants Weighing Less Than 6 kg: An Initial Indian Experience.

Background: Living donor liver transplantation in small infants is a significant challenge. Liver allografts from adults may be large in size. This is accompanied by problems of graft perfusion, dysfunction, and the inability to achieve primary closure of the abdomen. Monosegment grafts are a way to address these issues.

Methods: Two recipients in our cohort weighed less then 6 kg. The prospective left lateral segments from their donors were large for size. Therefore, monosegment 2 liver grafts were harvested. Data regarding the preoperative, intraoperative, and postoperative events in the donor and the recipient were recorded.

Results: We were able to achieve significant reduction in the sizes of the grafts harvested. The donors underwent surgery and hospital stay uneventfully. The recipients had normal graft perfusion and no graft dysfunction, and we could achieve primary abdominal closure. One recipient had self-limiting bile leak postoperatively.

Conclusions: Monosegment 2 liver allografts are safe and effective for use in living donor liver transplantation in small infants weighing less than 6 kg.
