been reported at 2 per 100,000 admissions over a period of 20 years at one center. The overall mortality associated with mesenteric ischemia is between 60% and 93% but rises precipitously once bowel wall infarction has occurred. Mortality remains greatest for acute mesenteric ischemia resulting from obstruction or embolic phenomena. Patients with an early manifestation of NOMI have mortality ra...

Non-occlusive mesenteric ischemia (NOMI) refers to all types of mesenteric ischemia without any organic blockage of blood vessels. It is usually seen in elderly age group with risk factors of previous myocardial infarction, congestive cardiac failure, aortic insufficiency, renal or liver impairment and post-cardiac surgery. Amongst all the cases of acute mesenteric ischemia, NOMI constitutes 20...

Acute mesenteric ischemia and infarction is an emergent situation associated with high mortality, commonly due to emboli or thrombosis of the mesenteric arteries. Embolism to the mesenteric arteries is most frequently due to a dislodged thrombus from the left atrium, left ventricle, or cardiac valves. We report a case of 70-year-old female patient with an acute small bowel infarction due to a m...

INTRODUCTION Acute mesenteric ischemia (AMI) is a rare but very severe complication of heart surgery, due especially to the delay in setting the correct diagnosis and choosing the appropriate treatment. There are 4 types, but the most frequent is nonocclusive mesenteric ischemia (NOMI). The main mechanism is represented by great decrease or maldistribution of the splenic blood flow, with negati...

This article briefly reviews the various etiologies, presentation, and diagnosis of different types of mesenteric ischemia. Operative management techniques and the applicability of percutaneous endovascular intervention are discussed. Finally, the authors explore emerging technologies that have the potential to further improve diagnosis and treatment of this frequently lethal disease process.
