自体肝移植术中静脉转流技术的探讨

摘要

肝移植是治疗终末期肝病及肝脏肿瘤的重要手段.为缓解供体的缺乏,自体肝移植(autologous liver transplantation,ALT)作为对常规手术不能切除的肝占位性病变的补充技术日益受到青睐.但是,与同种异体肝移植相比,其无肝期持续时间长,对患者的影响更大.体外静脉转流(veno-venous bypass,VVB)作为一种保持无肝期血流动力学和内环境稳定的技术,已常规应用于ALT术中.本文就ALT术中的静脉转流(VVB)技术进行探讨.%Liver transplantation is the main treatment for end-stage liver diseases and liver tumor.To solve the problem of the insufficient donor liver,autologous liver transplantation (ALT) is becoming widely acknowledged,which could serve as a complementary technique for treating unresectable liver space-occupying lesions in routine operation.However,compared with allogeneic liver transplantation,the long anhepatic phase during ALT may influence the outcome of such patients.Veno-venous bypass (VVB) as a technology which can maintain the stability of hemodynamics and internal environment in the anhepatic phase is routinely used in ALT.In this paper,the application of VVB in the ALT was mainly discussed.
