A modification of the mesocaval interposition H shunt utilizes the anterior cephalad portion of the superior mesenteric vein on top of the uncinate process of the pancreas as the site of anastomosis. This site is above the branches of the superior mesenteric vein and ensures a vein of large caliber. When the graft is anastomosed to this portion of the vein, it assumes a C configuration.
肠系膜上腔静脉间置H型分流术的一种改良方法是利用肠系膜上静脉位于胰腺钩突上方的头侧前部作为吻合部位。该部位在肠系膜上静脉分支之上,可确保有大口径的静脉。当移植物与该部分静脉吻合时,会呈C形结构。
