PY - 2016 T2 - Zollinger's Atlas of Surgical Operations, 10e AB - Acute mesenteric fischemia may develop on top on chronic mesenteric ischemia due to an underlying atherosclerotic lesion, but may also occur de novo due to an embolic event. Typically this is a result of cardiac dysfunction, including acute MI, cardiac aneurysm, and dysrhythmia. The usual presentation is “pain out of proportion to physical findings,” where the patient complains of the worst abdominal pain they have ever had, but physical examination elicits a soft abdomen with no discrete tender areas. Acute mesenteric ischemia is a surgical emergency where time is of the essence to avoid full-thickness bowel necrosis and even death.
