[Studies of gastric circulation in the dog, II. Ligation of main arteries (author's transl)].
Following ligation of a single gastric artery total and regional gastric blood flows are measured using radioactive microspheres of 8 mu size. There is no significant influence on total gastric blood flow. Within the depending anatomical region no significant reduction of total wall blood flow can be determined. However, blood flow to the antrum mucosa is reduced to approximately 40% after ligation of any gastric artery. Thus, it can be concluded that ligation or embolisation of a single gastric artery in diffuse gastric bleeding does not necessarily reduce or terminate the bleeding.
