Popis: | Background: This study aimed to determine whether the porcine model could be adapted to accommodate living donor liver transplantation (LLT). Because the pig hepatic anatomy precludes a standard approach, a study was designed to evaluate the results using a segment of vascular prosthesis to replace the intrahepatic portion of the inferior vena cava (IVC) with establishment of hepatic venous drainage into the graft. Methods: A total of 10 LLT were performed using 20 pigs. After left hepatectomy, the intrahepatic IVC was replaced with a modified aorto-iliac prosthesis, anastomosing the proximal (aortic limb) to the infradiaphragmatic IVC, one distal iliac limb to infrahepatic IVC and the other (after shortening) to establish hepatic venous drainage after transplant. Conventional venous bypass was used, and no immunosuppressives were administered. Results: All donors survived the 10-day posthepatectomy observation period. Eight of the 10 transplanted pigs survived at least 2 days (mean 7.6 days; range 3–13 days). No evidence of caval graft thrombosis was observed. Conclusions: Replacement of the recipient intrahepatic IVC by a vascular prosthesis allows to overcome the major technical obstacle which has limited the use of pigs in LLT. |
