Abstract
In the course of an investigation into the blood vessels of the ulcerated stomach it became evident that the circulation through the gastric vessels is modified as a result of the conditions of surgical operation. The mucous membrane of stomachs removed at operation is observed to be excluded from the active circulation in the stomach wall, further studies indicating that this is brought about by an arterio-venous shunt, similar to that described by Trueta et al (1947) in the kidney. For the purpose of these experiments, radio-opaque substances were injected at a pressure of 150 mm. of mercury into the arteries of the stomach excised at operation (for duodenal ulcer), or removed from the cadaver. Arteriographs of the stomach wall were made, and then transverse sections of different areas of the wall were subjected to the technique of micro-arteriography (Barclay, 1947). In order to demonstrate the arteries and their branches down to the arterioles, a proprietary preparation of Bismuth Oxychloride, “Chlorbismol”* (20 per cent.) was used as the contrast medium, injected into one of the gastric or gastroepiploic arteries. This mass was chosen because it has a particle size too large to enter the capillaries, and it outlines the larger vessels perfectly. Such injection in the cadaver stomach shows that the larger arteries divide during their passage through the stomach wall to form a main plexus of smaller arteries (readily visible to the naked eye on dissection) lying in the submucous layer between the muscle coat and the mucosa, over the whole stomach wall.
