Mesenteric ischemia is an uncommon disease most often seen in the elderly. This disease results from blood flow in the mesenteric circulation that inadequately meets metabolic needs of the visceral organs and, if untreated, eventually leads to necrosis of the bowel wall. Mesenteric ischemia is divided into 2 types: acute mesenteric ischemia (AMI) and chronic mesenteric ischemia (CMI). Delayed diagnosis of CMI can lead to AMI. AMI is associated with extremely high mortalities. Early diagnosis via computed tomography angiography and prompt revascularization via endovascular therapy are recommended for symptomatic patients who have not developed bowel ischemia and necrosis.
