The Hidden Culprit in a Massive Episode of Hematemesis: A Dieulafoy's Lesion
نویسندگان
چکیده
A Dieulafoy's lesion is described as a tortuous, dilated aberrant submucosal vessel that can penetrate through the mucosa and rupture spontaneously, resulting in severe gastrointestinal bleeding. The lesion is most commonly found in the proximal stomach. Historically, it has had up to an 80% mortality rate because of its tendency to cause intermittent but severe bleeding and diagnostic challenges. We report a case of a young male with recurrent severe upper gastrointestinal bleeding with extensive prior investigations failing to reveal the source of bleeding. Computed tomography angiography of the abdomen correctly identified Dieulafoy's lesion of the stomach, and it was subsequently confirmed and successfully treated with interventional radiology (IR)-guided mesenteric angiography and embolization.

Background. In 1897, Dieulafoy was the first to characterize a gaping arteriole within the gastric mucosa causing massive hematemesis, designating it as "exulceratio simplex." A hundred years later, this vascular abnormality, now commonly referred to as a "Dieulafoy lesion," has been identified through the entire gastrointestinal tract and the bronchus. Objectives and Methods. As the original f...

Gastric Dieulafoy's lesion (DL) is a potentially fatal entity that causes upper digestive hemorrhage as a consequence of the erosion of an abnormal large-caliber artery in the submucosa of the gastrointestinal tract. We report the case of a 59-year-old female patient admitted to the emergency facility due to melena without any active sign of bleeding during the esophagogastroduodenoscopy. Unexp...
