Answer

The colon is supplied by the superior mesenteric artery (SMA) and the IMA. A compromise of blood supply to the colon results in ischemic colitis that can progress to bowel infarction if left untreated. Infarction can result from an occlusive embolus in one of the arteries that supplies the colon or from the vasoconstrictive effects of strong vasopressors. An infarcted bowel can rapidly develop into a perforated bowel. Therefore, bowel infarction or colon ischemia is a surgical emergency.
