Abstract

 


Dieulafoy vascular lesion, a rare cause of massive upper gastrointestinal bleeding, has a high mortality rate when diagnosis and treatment are delayed. A 41-year old woman was admitted to the hospital because of massive upper gastrointestinal bleeding. Upper gastrointestinal endoscopy did not revealed localization of bleeding. Emergency surgery was performed and localization of bleeding was seen within 4 cm of the gastroesophageal junction on lesser curvature on the stomach. Histopathoiogicai study of wedge resection material showed Dieulafoy vascular malformation. Dleulafoy's lesion Is a difficult lesion to recognize. It should be considered when evaluating any unexplained acute and recurrent major gastrointestinal bleeding.
