Liver transplantation using a right lateral sector graft from a living donor to her granddaughter.
One of the major concerns regarding living-related liver transplantation is graft-size disparity. The left liver graft is too small while the right is too large in some recipients. To overcome this problem, the right lateral sector (Segments VI and VII) was transplanted from a living donor (55 kg) to her granddaughter (17 kg). The common hepatic trunk had to be anastomosed end-to-end to the graft hepatic vein without being compressed by the graft overriding the vena cava and without unfavorable tension of the anastomosis. The anterior wall of the hepatic vein of the donor was resected as much as possible. The superficial left, left, middle and right hepatic veins of the recipient were made confluent by incision of the intervening venous walls, and the nicks were sutured to form a wide and long common venous trunk. The recipient received a graft corresponding to 75% of her standard liver volume. She was complicated with gastric dilation and acute rejection, but recovered with no signs of anastomotic stricture. Right lateral sector graft obtained by this innovative procedure may be useful for overcoming borderline graft-recipient size and shape differences.
