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.
在成人活体肝移植（LDLT）中，目前尚无关于门静脉（PV）重建中静脉搭桥或间置血管管理的数据。研究了使用冷冻保存的静脉移植物作为PV血管的可行性。将冷冻保存的静脉（n = 23）用作补片、间置或搭桥移植物。将通畅结果与无静脉补片吻合（n = 217）或自体静脉移植（n = 10）的结果进行比较。冷冻保存静脉移植物的5年原发性和继发性通畅率分别为58%和79%。总之，我们的数据表明，在成人LDLT的PV重建中，冷冻保存静脉移植物作为血管的使用应受到限制。
