The celiac axis is commonly involved by generalized atherosclerosis and other vascular diseases. Derrick, Pollard, and Moore (3) found its diameter narrowed in 44 per cent of 110 unselected autopsy cases. In 21 per cent of these cases, moreover, the narrowing was more than 50 per cent. In spite of this high incidence of severe celiac stenosis, surprisingly little note is made of celiac occlusive disease by authors writing about abdominal angina. Since the pancreaticoduodenal arcades connect major branches of the celiac and superior mesenteric arteries, an evaluation of both vessels, as well as of the inferior mesenteric artery, is necessary in the investigation of intestinal vascular insufficiency. Several authors point out that two of these three major aortic visceral branches must be narrowed before symptoms of the syndrome appear (8, 10). When such is the case, the perfusion pressure distal to the stenoses is quite low, providing flow adequate to preserve the life, but not the function, of the intestin...
