Chronic occlusion of splanchnic artery

The nutritional arteries of the gastrointestinal tract are mainly celiac artery, superior mesenteric artery and inferior mesenteric artery. When it develops chronic occlusion, there are three possible consequences: the establishment of a sufficient collateral circulation; intestinal infarction occurs; intestinal ischemia occurs without infarction. The latter is because post-prandial bowel pain occurs because the collateral circulation is sufficient to maintain the vitality of the bowel, but not enough to maintain the physiological functions required during eating. It is called intestinal colic because of its clinical condition similar to angina pectoris and intermittent claudication.
