肝段 切除和 (或 )肝段 切除有时需同时节段性切除右肝静脉 ,如在肝癌侵犯或邻近肝静脉。在上述情况 ,重建肝静脉被认为是保存术后肝段 功能的重要步骤 ,尤在肝恶性肿瘤伴肝硬化病例。动物实验证实结扎肝静脉后受侵的肝段借藉肝内静脉侧支循环的建立而回复正常结构 ,由此可 Segmental resection and / or resection of the liver segment may sometimes require segmental resection of the right hepatic vein, as in the case of invasion or adjacent hepatic vein. In these circumstances, the reconstruction of the hepatic vein is considered as an important step to preserve the function of the postoperative liver segment, especially in cases of liver malignancy with cirrhosis. Animal experiments confirmed that after the hepatic vein ligation of the hepatic segment by the establishment of the intrahepatic venous collateral circulation to restore normal structure, which can be
