Small bowel ischemia (also called mesenteric ischemia) is a potentially life-threatening group of conditions that reduce blood flow to the small intestine (e.g., duodenum, jejunum or ileum). Symptoms can range from mild to severe depending on the cause. It’s important to see your doctor if you have sudden, severe abdominal pain. Intestinal ischemic syndromes -- also called visceral or mesenteric ischemic syndromes -- occur when blood flow to the bowel or gastrointestinal system (intestines) is decreased because of a blood vessel blockage. Intestinal ischemia is a serious condition caused by insufficient blood flow to part of the intestine. Whether it affects the small or large intestine, the chief symptom is pain.

It develops when there isn’t enough blood flow to the colon. IC can occur at any age, but it’s most common among Acute intestinal ischemia is a gastrointestinal emergency resulting from a sudden decrement in intestinal blood flow. It may occur as a consequence of mesenteric vascular occlusion and/or hypoperfusion and may involve the small intestine or colon.

This article is focused on acute mesenteric ischemia. Intestinal ischemia is caused by a reduction in blood flow to a level that is insufficient for the delivery of oxygen and nutrients required for cellular metabolism [ 1 ]. It can be related to acute arterial occlusion (embolic, thrombotic), venous thrombosis, or hypoperfusion of the mesenteric vasculature causing nonocclusive ischemia. Constipation, irritable bowel syndrome (IBS), fecal impaction, colonic obstruction and any other condition that increases the intraluminal pressure, which may compromise the blood flow the colonic wall, leading to ischemic injury Extent of ischemic changes in the intestines depends on the severity, rate of onset and duration of ischemia stricture, ischaemic colonic stricture, ischemic megacolon, ischaemic megacolon, colon cast, and colonic cast. The references obtained were reviewed and the best studies were included as evidence Ischemia is a condition in which the blood vessels become blocked, and blood flow is stopped or reduced. When blood flow is diminished to a body part, that body part also does not receive adequate oxygen. Ischemia can occur anywhere in the body, including the

Mesenteric ischemia is a medical condition in which injury to the small intestine occurs due to not enough blood supply. It can come on suddenly, known as acute mesenteric ischemia, or gradually, known as chronic mesenteric ischemia. Small bowel ischemia may be a life-threatening condition, arising from any one of numerous causes of disturbance of the normal blood flow through the small bowel wall. Gross and microscopic spectrum of ischemic colitis varies by the duration and extent of ischemia Classic ischemic type mucosal injury pattern is described as superficial mucosa necrosis / regeneration, withered crypts and lamina propria hyalinization; this histology is not specific for ischemia and may be seen with infections (C. difficile, E. coli O157:H7), medications and inflammatory bowel Bowel Ischemia - video series Robin Smithuis Alrijne hospital in Leiderdorp, the Netherlands Bowel wall is usually not thickened in acute mesenteric arterial occlusion Acute arterial bowel ischemia usually has little mesenteric infiltration or ascites – Lack of bowel mucosal enhancement due to compromised arterial flow – CT signs of embolic ischemic injury to other organs (e.g., spleen and kidneys) – Ischemic bowel is a relatively frequent presentation to general surgery. A strong clinical suspicion assists the radiologist in making a confident diagnosis - the signs can be variable and range from subtle to frank.
