Abstract

The surgical treatment of occlusive acute mesenteric ischemia (AMI) without revascularization is associated with an 80% overall mortality. Early diagnosis is crucial, and revascularization may reduce overall mortality in AMI by up to 50%. A diagnosis of AMI requires a high index of clinical suspicion and the collaborative effort of emergency department physicians, general and vascular surgeons, and radiologists. This article provides an overview of the etiology, physiology, evaluation, and management of acute mesenteric ischemia.

Keywords: acute mesenteric ischemia; angioplasty; embolectomy; endovascular procedures; endovascular therapy; mechanical thrombolysis; mesenteric venous thrombosis; nonocclusive mesenteric ischemia; surgical treatment.
