在50具成人男性尸体,对胰腺动脉的研究表明: 一、胰头上部由胰十二指肠上(前、后)动脉分布;胰头下部由胰十二指肠下(前、后)动脉分布。胰十二指肠下动脉的起源有更多的变异。 二、胰十二指肠上、下动脉在胰头的前、后面构成了“前弓”和“后弓”。在胰头前面由胰十二指肠上前动脉的左支与胰背动脉的右支构成“胰前弓”,出现率为92％。 三、胰背动脉起源于脾动脉的为“常见型”,出现率为46％;起源于脾动脉以外的部位为“变异型”,出现率为50％;缺少胰背动脉的为4％。 四、胰支中最粗大的胰大动脉,出现率为78％,多起于脾动脉的第3段。 五、胰尾动脉有1—4条,以1条的类型居多数(40％),多起于脾动脉下干,缺少胰尾动脉的有8％。
In 50 adult male cadavers, studies of the pancreas arteries revealed that: 1. The upper part of the pancreas is distributed by the upper (anterior and posterior) arteries of the pancreas; the lower part of the pancreas is covered by the lower (anterior and posterior) arteries of the pancreas and the duodenum distributed. The origin of pancreaticoduodenal artery has more variation. Second, the pancreatic and duodenal upper and lower arteries in the head and back of the pancreas constitute the “front bow” and “rear bow.” In front of the pancreatic anterior pancreaticoduodenal artery by the left branch of the dorsal artery with the right branch of the “anterior pancreatic arch”, the incidence was 92%. Third, pancreatic dorsal artery originated in the splenic artery as a “common type”, the rate was 46%; originated in the splenic artery outside the site as a “variant”, the incidence was 50%; lack of pancreatic dorsal artery was 4%. Fourth, the largest pancreas in the pancreas, the incidence of 78%, mostly in the third paragraph of the splenic artery. Five, pancreatic tail artery 1-4, the majority of the type 1 (40%), mostly from the splenic artery, dry, lack of tail artery 8%.
