Acute mesenteric ischemia refers to the sudden onset of small intestinal hypoperfusion, which can be due to reduction or cessation of arterial inflow. Ischemia due to acute mesenteric arterial occlusion can be caused by embolic obstruction of the intestinal blood supply, most commonly to the superior mesenteric artery (SMA). Acute ischemia can also occur due to acute thrombotic obstruction, often in the setting of an already diseased mesenteric vessel (eg, atherosclerosis).
