背驮式肝移植中肝静脉流出道阻塞的预防

目的　探讨腔静脉成形术在背驮式肝移植中的应用价值及防止移植肝流出道阻塞中的作用。方法　 3位终末期肝病病人的供肝下腔静脉及受体肝后下腔静脉 (包括肝静脉 )均作了成形术 ,在单独股—腋静脉转流术下行改良背驮式肝移植。结果　 3例病人术中均非常平稳 ,手术时间、无肝期缩短 ,出血量减少 ,术后肝功能恢复快 ,康复顺利 ,无并发症发生。结论　腔静脉成形术可防止背驮式肝移植肝静脉流出道阻塞 ,术中对受体血流动力学干扰小 ,缩短无肝期 ,减少并发症发生

Prevention of outflow block in piggy back liver transplantation

Objective To investigate the impact of cavoplasty on the piggy back liver transplantation and on the prevention of hepatic outflow block. Methods Three patients received modified piggy back liver transplantation with venacavoplasty under single veno venous bypass. Results All the recipients had stability of dynamic circulation, short anhepatic phase and decreased hemorrhage during operation. Postoperatively all the patients recovered quickly with good liver function without any complications. Conclusions Venacavoplasty may overcome outflow block in piggy back liver transplantation and the technique can shorten anhepatic phase and decrease complications.
