肝动脉变异较多见,在国内外文献中已有了不少的报道.但在同一具尸体上集合了几种变异的情况则少见.作者在指导学生局解实习中发现了一例,报告如下:老年男尸,身长约175cm,极度消瘦,腹部无任何手术及外伤疤痕.在解剖肝蒂时发现,左、中、右三支肝动脉分别来源于不同的动脉,属非典型分布.(1)迷走(替代)肝左动脉,异位起自胃主动脉,距胃左动脉起点约3cm弓向上的部位发出.迷走肝左动脉发出后走在网膜囊的后壁斜向右上,行至肝门的左侧直接入左半肝.该血管外径粗约0.3cm,全长约7.5cm.(2)肝中动脉是肝总动脉的分支.相当于肝固有动脉的发出部位,发出了两支细小的肝中动脉取代了肝固有动脉.两支间距在0.5～0.8cm之间,自起点垂直上行于肝蒂的左前方,伴肝总管和门静脉入肝门 .管径均未超过0.1cm.(3)迷走(替代)肝右动脉,起自右肾动脉,距右肾动脉起点的腹主动脉约2.5cm处向上发出一支较粗大的血管,直径约0.4cm,当该血管路经右肾上腺 Hepatic artery variation is more common in the literature at home and abroad have been a lot of reports.But in the same body of a collection of several variants are rare.An instruction in the student Bureau of internship found in an example, the report is as follows : Aged male body, about 175cm in length, extremely thin, abdomen without any surgery and traumatic scars in the dissection of liver pedicle, found that the left, middle and right three hepatic artery from different arteries, are atypical distribution. ) Vagus (instead of) the left hepatic artery, the ectopic origin from the aorta, from the starting point of the left gastric artery about 3cm arch upward part of the issue .After the left hepatic artery vagus artery left in the posterior wall of the omentum obliquely to the right, The left hepatic portal directly into the left hemilivergus.The diameter of the vascular diameter of about 0.3cm, a total length of about 7.5cm. (2) The middle hepatic artery is the branch of the common hepatic artery, which is equivalent to the site of the hepatic artery, Two small middle hepatic artery replaces the hepatic artery.The distance between the two is between 0.5 ~ 0.8cm, vertical upward from the starting point in the left front of the pedicle, with the hepatic duct and portal vein into the portal.The diameter of no more than 0.1 (3) vagal (alternative) right hepatic artery, from the right renal artery, from the right renal artery from the beginning of the abdominal aorta about 2.5cm up issued a thicker blood vessels, a diameter of about 0.4cm, when the blood flow through the right adrenal gland
