| Abstract: | No data are available for the management of venous jump or interposition conduits for portal vein (PV) reconstruction in adult living donor liver transplantation (LDLT). The feasibility of using cryopreserved vein grafts as PV conduits was examined. Cryopreserved vein (n = 23) was used as a patch, interposition, or jump graft. The patency results were compared with those of anastomosis without vein patch (n = 217) or those with vein autografts (n = 10). The 5-yr primary and secondary patency rates of the cryopreserved vein grafts were 58% and 79%, respectively. In conclusion, our data indicate that the use of cryopreserved vein grafts should be limited as conduits in PV reconstruction in adult LDLT. |
