Gastric Arteriovenous Malformation with Characteristic Endoscopic Findings.

Gastric Arteriovenous Malformation with Characteristic Endoscopic Findings. Intern Med. 2018 Mar 09;: Authors: Hirayama Y, Takai C, Korekawa K, Saitoh M, Akasaka A, Nagasawa H, Iwai W, Hachimori H, Satoh M, Yajima N, Oki M Abstract Gastric arteriovenous malformation (AVM) is an uncommon cause of upper gastrointestinal bleeding, and the endoscopic findings are unclear. We herein describe a case of gastric AVM in a 28-year-old man. Esophagogastroduodenoscopy showed a Dieulafoy lesion surrounded by a red mucosa with a sharp margin, which implied blood vessel malformation. Computed tomography angiography and conventional angiography revealed aggregated vessels on the greater curvature. Partial gastrectomy was performed, with no recurrent bleeding postoperatively. The histopathological diagnosis was AVM. We conclude that gastric AVM should be considered in the differential diagnosis of patients who present with a Dieulafoy lesion surrounded by a red mucosa.
