正常的结肠中动脉位于胰头下方或胰颈下缘,起自肠系膜上动脉,发出后即进入横结肠系膜,偏系膜右侧走向结肠右曲并分为左右两支进入横结肠肠壁。我们在做解剖操作时,发现一罕见的结肠中动脉变异,现报告如下。 成年男尸,发育正常,腹部无手术切口疤痕。解剖腹腔时发现在胰头附近距肠系膜上动脉起始部约5cm向右发出一结肠中动脉主干,主干向上方行走3cm后急转向右下方,形成一比较粗大的动脉弓。该弓延续至结肠右曲下方8cm处其终末支和右结肠动脉的分支吻合。从右至左动脉弓上依次发出四条分支,分别进入横 The normal colonic artery is located in the lower part of the head of the pancreas or the lower edge of the pancreatic neck, from the superior mesenteric artery, after entering the transverse mesocolon, the right side of the partial membrane to the right colon and into the left and right into the transverse colon wall. We are doing anatomy operation, found a rare intra-arterial artery variation, are reported as follows. Adult male body, normal development, no incision in the abdomen scar. Anatomy of the abdominal cavity was found in the vicinity of the head of the pancreas from the beginning of the superior mesenteric artery about 5cm to the right of the trunk of an artery in the colon, the trunk to the top of the walk after 3cm anxious to the lower right, forming a relatively thick aortic arch. The bow extends to the right colon of the colon 8 cm below the branch and the right colon artery anastomosis. From the right to the left of the arch, there are four branches in turn, entering the transverse
