Diagnosis and Management of Nonocclusive Mesenteric Ischemia

Abstract

Acute hypoperfusion of the bowel without mechanical occlusion of the arterial or venous circulation is referred to as nonocclusive mesenteric ischemia (NOMI) and is responsible for approximately one fourth of all arterial causes of mesenteric ischemia. Patients present with nonspecific symptoms, making clinical diagnosis difficult. Prognosis is poor with high mortality rates. Mortality rates have improved during the past two decades from 80 to 50% due to early diagnosis and prompt initiation of treatment. In this review, we discuss the etiology, pathophysiology, and symptoms of NOMI as well as radiological findings and management along with comprehensive review of the literature.
