Role of the Pulsatile Thrust of the Aorta in Genesis of Gastric Ulcer. ∗

Abstract

Conclusions and summary

1. Retroaortic placement of the fundus of the dog's stomach is followed by development of gastric ulcer at site of impingement of the aortic thrust upon the gastric wall. Perforation with formation of a gastroaortic fistula was a frequent sequel.

2. It is not unlikely in man that the mid lesser curvature gastric ulcer owes its origin in part to the thrust of aortic pulsations.
