Gradual Occlusion of Mesenteric Vessels With Ameroid Clamp

Abstract

WITH THE continuous increase in life expectancy, the degenerative changes as cause of disease are found more often. Among them, alterations in blood vessels are common. These have been found mainly in the blood supply of the extremities, which have seen most of the advances in diagnosis and treatment. Pathological alterations in the mesenteric vasculature have only come to be fairly understood and amenable to repair during the last seven years.¹ Although abdominal catastrophes caused by sudden embolization or thrombosis of the mesenteric vessels with massive infarction of the small and large bowel were known previously, syndromes like intestinal angina have only recently been fully understood, diagnosed before universal changes occurred, and subjected to successful surgical therapy. However, there remain some aspects on which difference of opinion persists. One aspect which we have tried to elucidate is how much of the lumen of the three main arterial vessels (celiac
