Mesenteric ischemia.

This article reviews the presentation, diagnosis, evaluation, and treatment of the various forms of mesenteric ischemia, including acute and chronic ischemia. In addition, nonocclusive mesenteric ischemia and median arcuate ligament compressive syndrome are covered. The goals are to provide a structured and evidence-based framework for the evaluation and management of patients with these intestinal ischemia syndromes. Special attention is given to avoiding typical pitfalls in the diagnostic and treatment pathways. Operative techniques are also briefly discussed, including an evidence-based review of newer endovascular techniques.
