改良腔门静脉半转位肝移植术(附二例成功报告)

目的:探讨改良的腔门静脉半转位肝移植术治疗门脉系统广泛栓塞的外科处理方法.方法:对2例门脉系统广泛栓塞患者进行改良的腔门静脉半转位肝移植术(采用腔静脉肠系膜上静脉吻合 辅助性门静脉脾静脉吻合重建门脉血流),观察术后肝功能恢复情况、术后门脉血流灌注、术后肾功能不全、下肢水肿及食管胃底静脉曲张等情况.结果:2例患者手术顺利,术后肝功能恢复正常,门脉血流灌注良好,无肾功能不全、下肢水肿及食管胃底静脉曲张等并发症.结论:改良的腔门静脉吻合半转位肝移植术是治疗门脉系统广泛栓塞的有效方法.

Modified cavoportal hemitransposition for liver transplantation: a report of 2 successful cases

Objective:To study the outcomes of a modified cavoportal hemitransposition technique for liver transplantation in treatment of diffuse portal vein thrombosis.Methods: Two patients with diffuse portal vein thrombosis received liver transplantation by modified cavoportal hemitransposition.Anastomosis between the native inferior vena cava and the graft coeliomesenteric vein and adjuvant anastomosis between the native portal vein and graft spleen vein were performed to reconstruct the blood flow of portal vein.The post-operation liver function,portal flow,renal insufficiency,edema of lower extremities,and the varices of esophagus or gastric fundus were observed.Results: The operation was successful in both cases,with normal post-operation liver function and satisfactory portal flow.There was no complication such as renal insufficiency,edema of lower extremities,and varices of esophagus or gastric fundus.Conclusion: This modified cavoportal hemitransposition technique in liver transplantation is proved effective for diffuse portal vein thrombosis.
