肝动脉的解剖学观测及其临床意义

Anatomic observation of hepatic artery and its clinical significance

对８０例成人肝动脉的来源、数目、分支类型及主要分支的长度、口径进行了观察和测量。其中只有１支典型的肝固有动脉者占７７．５％，有１支副肝动脉者占２０％，有２支副肝动脉者占２．５％。副肝动脉分别来自胃左动脉（１６％），腹腔于（５％）和肠系膜上动脉（４％）。肝右动脉长３．７±１．５ｃｍ，口径４．２±１．１ｍｍ。肝左动脉长２．４±１．４ｃｍ口径３．３±１．０ｍｍ。因而在行肝段移植术时，于肝右动脉根部截断血管较为有利。本文还对肝动脉在肝段移植中的其它临床问题进行了讨论。

he origin. distribution and branch type of the hepatic artery and the lengths. diameters of itsmain branches were dissected and observed on 80 adult cadavers. A typical proper hepatic arterywas observed in 77.5%of the specimens. while one accessory hepatic artery. and two accessoryhepatic arterise were recorded in 20%and 2.5%respectiveely. The accessory hepatic artery wasderived differently from the left gastric artery(16%),the celiac trunk( 5%)and the superiormesenteric artery(4%).The right branch of the hepatic artery is 36.9±14.6 mm in length and4.2±1. 1 mm in diameter.The left branch of the hepatic artery is 23.7±13.7 mm in length and3.3±1.0 mm in diameter. The relationship between the clinical anatomy of hepatic artery and thehepatic segmental transplantation were discussed.
