左外区活体肝移植动脉的临床应用解剖研究

目的 观察肝左区肝动脉解剖结构，模拟肝左外区活体肝移植动脉切取方法。方法 解剖非肝病死亡之成人甲醛固定尸体肝脏标本30例，观察新鲜成人尸体肝脏铸型标本30例，测量肝左及左外区动脉长度、管径及属支分布情况。结果 左半肝动脉的血供来自肝固有动脉、肝左动脉、肝中动脉，肝外迷走动脉支有左膈下动脉、胃左动脉和胃右动脉，并于不同部位发出后分别进入左外区上、下段。结论 左半肝动脉主要有5种类型，因此解剖变异较多，左外区活体取肝前应仔细研究其结构特点，设计合理的切取模式；移植前肝动脉需进行必要的整形，以便与受体动脉吻合。

Applied Anatomy of Hepatic Arteries in Living Liver Transplantation of Left Lateral Lobe

Objective To study the anatomy of the hepatic arteries and imitate the way to deal with the hepatic arteries in the living liver transplantation of the left lateral lobe.Methods Thirty normal adult livers were anatomyzed and 30 casting models of livers were observed. The lengths, diameters and distributaries of the hepatic arteries were described Results The blood supply of the left lateral region came from proper hepatic artery, left hepatic artery and middle hepatic artery. The aberrant arteries included left inferior phrenic artery, left gastric artery and right gastric artery. They branched to supply the upper segment and the inferior segment Conclusion There are five types of hepatic arteries to supply the left liver lobe. The anatomy of hepatic arteries should be studied and a reasonable approach to gain a liver graft should be designed before transplantation. The hepatic arteries should be dealt with so as to anastomose with recipient hepatic arteries.
