Portal vein thrombosis is observed in up to 10% of liver transplant candidates, hindering execution of the procedure. A dilated gastric vein is an alternative to portal vein reconstruction and decompression of splanchnic bed. We present two cases of patients with portal cavernoma and dilated left gastric vein draining splanchnic bed who underwent liver transplantation. The vein was dissected and sectioned near the cardia; the proximal segment was ligated with suture and the distal segment was anastomosed to the donor portal vein. Gastroportal anastomosis is an excellent option for portal reconstruction in the presence of thrombosis or hypoplasia. It allows an adequate splanchnic drainage and direction of hepatotrophic factors to the graft.
在高达10%的肝移植候选者中观察到门静脉血栓形成,这阻碍了手术的实施。扩张的胃静脉是门静脉重建和内脏床减压的替代方法。我们报告了两例患有门静脉海绵样变性且内脏床引流的扩张左胃静脉的患者接受肝移植的病例。在贲门附近解剖并切断该静脉;近端用缝线结扎,远端与供体门静脉吻合。胃肠门静脉吻合术是存在血栓形成或发育不全时门静脉重建的极佳选择。它能实现充分的内脏引流,并使促肝细胞生长因子流向移植物。
