肝移植中门静脉血栓的处理经验

目的 探讨肝移植术中门静脉血栓的几种处理方法及其疗效.方法 回顾性分析773例次肝移植临床资料.773例中,107例病人有门静脉血栓,其中59例Ⅰ级;33例Ⅱ级;12例Ⅲ级;3例Ⅳ级.Ⅰ、Ⅱ级组行血栓切除或取栓术;Ⅲ级采用取栓术或肠系膜上静脉架桥的方式重建供肝门静脉;对Ⅳ级采用改良门腔静脉半转位术和门静脉胃冠状静脉吻合重建供肝门静脉.结果 Ⅰ、Ⅱ级组移植肝功能恢复良好,围手术期病死率为4.3%.Ⅲ级取栓组5例肝功能恢复良好,围手术期无死亡.静脉架桥组7例中有2例肝功能恢复不佳,围手术期病死率为28.6%.Ⅳ级组肝功能恢复良好,围手术期无死亡.结论 门静脉血栓已非肝移植禁忌证,根据血栓的不同情况采取合理的手术方式重建门脉系统可以获得良好的治疗效果.

Management experience of portal vein thrombosis of liver transplantation

Objective To investigate the surgical options for the management of portal vein thrombosis (PVT) during liver transplantation and its impact on the outcome of patients. Methods 773 cases of liver transplantation were analyzed retrospectively. PVT occurred in 107 patients, inclu-ding 59 of grade Ⅰ ,33 of grade Ⅱ, 12 of grade Ⅲ and 3 of grade Ⅳ. Simple thrombectomy or thrombus-extraction was performed in grade Ⅰ and Ⅱ. 12 patients with grade Ⅲ received thrombus-extraction or using the donor iliac vein to act as a bridge between the donor portal vein and host superior mesenteric vein. Two cases of grade Ⅳ received a modified cavo-portal hemitransposition and one case received portal-vena coronaria varication anastomosis. Results Liver function had a good recover and the perio-perative mortality is 4. 3% in grade Ⅰ and Ⅱ. In grade Ⅲ , 5 cases received thrombus-extraction had a normal liver function after transplantation and had no died. 2 cases among the other 7 cases using por-tal vein reconstruction had bad liver function and died. The liver function recovered well after trans-plantation and there was no died in grade Ⅳ. Conclusions PVT is not a contraindication for liver transplantation. Good results can be obtained by applying reasonable operative procedures individually.
