31条犬施行门腔静脉吻合术,术后24小时内死亡6条,其他25条均获长期存活。经验与体会是:吻合口位置宜低,作吻合处的下腔静脉和门静脉分支仅游离其两旁的浆膜;用心耳钳阻断门腔静脉血流,且钳刃越薄越好;吻合口前后壁均用一般连续缝合;吻合口必须大于1.5公分。本手术在实验医学的用途是:作为外科性急性肝昏迷动物模型的第一步造型手术;研究慢性肝脑病时中枢神经组织化学和病理形态学改变;研究肝移植供肝灌注液的最佳温度和成分;研究和选择用于肝保存的细胞膜稳定剂;研究血浆各种氨基酸在肝脑病时的作用。
Thirty dogs were treated with portal venous anastomosis, 6 died within 24 hours after operation, and the other 25 were all long-term survived. Experience and experience are: anastomotic position should be low for the anastomosis of the inferior vena cava and portal vein branches only free both sides of the serosa; with ear earplugs blocking the portal venous blood flow, and the pliers blade as thin as possible; anastomosis Before and after the wall are used for general continuous suture; anastomotic must be greater than 1.5 cm. The use of this procedure in experimental medicine is as a first-step modeling surgery in a surgical acute hepatic coma animal model; in the study of histochemistry and histopathology of central nervous system in chronic hepatic encephalopathy; to study the optimal temperature for hepatic transplants And composition; research and selection of cell membrane stabilizer for liver preservation; study the role of various plasma amino acids in hepatic encephalopathy.
