我们在解剖过程中发现一男性成年人的腹腔动脉分支异常,出现食管、肝、胆、胰迷走动脉。一、腹腔动脉于第十二胸椎体下1/3的前方由腹主动脉发出后,于其上壁先发出一长0.2cm的膈下动脉短干,然后发出胃左动脉,最后分为脾动脉和肝总动脉二终末支.膈下动脉由腹腔动脉发出后,立即分为左、右膈下动脉向外上布于膈肌。二、食管迷走动脉:肝固有动脉由肝总动脉发出后分为肝右动脉、肝食管动脉、幽门动脉和胃右动脉。肝食管动脉先后分出肝中和肝左动脉后向左至食管腹段分支特称其为食管迷走动脉。三、胰横迷走动脉:胃十二指肠动脉于幽门下方分出胰十二指肠前上动脉后不久,即分为胃网膜右动脉和胰横迷走动脉。后者绕胰颈下缘至胰背面穿胰腺实质与胰大、胰尾动脉相吻合,分支供应胰腺血液。四、肝迷走动脉:由肠系膜上动脉后壁发出,在门静脉合成处与下腔静脉之间先向右,然后于胆总管左侧向上,走在肝总管后方与其交叉后进入Calot三角,分出胆囊动脉后继续向上,全长7.0cm,在门静脉右支右侧经肝门入肝右叶。五、胆囊迷走动脉:在Calot三角内由肝右迷走动脉分出后,水平向右长1.3cm,于胆囊颈上方达胆囊体左缘,分三支布于胆囊前后面及其左缘。
We found in the dissection of a male adult celiac artery abnormalities, there esophagus, liver, gallbladder, pancreatic vagal artery. First, the celiac artery in the twelfth thoracic vertebra in the lower third of the anterior in front of the abdominal aorta issued in its upper wall first issued a 0.2cm long subdural artery short dry, and then sent the left gastric artery, and finally divided into Splenic artery and hepatic artery two terminal .After the phrenic artery issued by the celiac artery, immediately divided into left and right subphrenic artery outward on the diaphragm. Second, esophageal vagal artery: After the hepatic artery is issued by the hepatic artery is divided into the right hepatic artery, hepatic esophageal artery, pyloric artery and right gastric artery. Liver and esophageal arteries have been separated from the liver and the left hepatic artery to the left esophageal branch branded as esophageal vagal artery. Third, the pancreas Fan vagus artery: Gastroduodenal artery in the pylorus out of pancreatic duodenal anterior superior artery soon after, that is divided into the right gastric artery and pancreas transverse vagal arteries. The latter around the lower edge of the pancreatic neck to the back of the pancreas through the pancreas and pancreatic parenchyma, pancreatic tail artery anastomosis, branch supply of pancreatic blood. Fourth, the liver vagus artery: issued by the posterior wall of the superior mesenteric artery, between the portal vein synthesis and inferior vena cava first to the right, and then left in the common bile duct up, walk in the rear of the hepatic duct and cross after entering the Calot triangle, out Continued upward after the cystic artery, total length 7.0cm, right portal vein in the right hepatic portal right hepatic lobe. Fifth, gallbladder vagal artery: In the Calot triangle by the right hepatic artery out of the artery, the level of 1.3cm long right, above the gallbladder neck gallbladder left margin, divided into three branches in front of the gallbladder and its left edge.
