Nonocclusive Mesenteric Ischemia Rescued by Immediate Surgical Exploration in a Boy with Severe Neurodevelopmental Disability

الملخص EN

Background.

Nonocclusive mesenteric ischemia (NOMI) defines acute mesenteric ischemia without occlusion of the mesenteric arteries.

The most common cause of NOMI is vasoconstriction or vasospasm of a mesenteric artery.

NOMI generally affects patients >50 years of age, and few cases have been reported in children.

Case Presentation.

A 15-year-old boy with severe neurodevelopmental disability developed sudden-onset fever, abdominal distention, and dyspnea.

Laboratory and radiological findings indicated acute intestinal obstruction and prerenal failure.

He developed transient cardiopulmonary arrest and hypovolemic shock.

Emergent laparotomy was performed, which revealed segmentally necrotic intestine from the jejunum to the ascending colon with pulsation of peripheral intestinal arteries, leading to a diagnosis of NOMI.

The necrotic intestine was resected, and stomas were created.

He was discharged on postoperative day 334 with short bowel syndrome as a complication.

Conclusions.

NOMI should be considered a differential diagnosis for intestinal symptoms with severe general conditions in both adults and children with underlying disease.

Immediate surgical exploration is essential with NOMI to save a patient’s life.
