Unexpected cause of chronic recurrent abdominal pain: mesenteric arteriovenous dysplasia/vasculopathy.

We would like to submit the manuscript entitled "Unexpected Cause of Chronic Recurrent Abdominal Pain: Mesenteric Arteriovenous Dysplasia/Vasculopathy" for publication in REED. Mesenteric arteriovenous dysplasia/vasculopathy (MAVD/V) MAVD/V is a rare, localized, noninflammatory, non-atherosclerotic form of mesenteric vasculopathy that involves both arteries and veins producing secondary ischemic changes and alterations in the intestinal mucosa. It was proposed for the first time in 2016. Chronic abdominal pain is the most common symptom, which tends to progressively aggravate, and can be accompanied by weight loss, diarrhea or constipation and bloody stools, only a few patients begin with acute abdominal pain.
