ヒト腹腔, 左胃, 脾, 肝, 上腸間膜, 下腸間膜, 下横隔動脈群の類型解剖学

Four cases of dissected human coeliac and other mesenterial arteries are presented. Typologic discussion of these cases indicates that the arterial system of human mesentery vessels basically consists of left gastric, splenic, (common) hepatic, superior mesenteric and inferior mesenteric arteries, and that these arteries, like the inferior phrenic and inferior rectal arteries, are originally paired vessels (left and right). The left gastric, (common) hepatic and superior mesenteric arteries are thus derived from the right-sided vessels, while the splenic and inferior mesenteric arteries arise from the left-sided vessels. The aberrant acces-sory colica media artery is a typical left-sided vessed. The celiac trunk is also left-sided vessed.
