위 동정맥기형에서 발생한 대량의 상부위장관 출혈

The arteriovenous malformation(AVM) of the gastrointestinal tract is a rare cause of gastrointestinal bleeding. With the increasing use of angiography over the past 30 years in the assessment of gastrointestinal bleeding, AVM has been more frequently recognized. There are few reports, however, about the arteriovenous malformation of stomach. From 1884, about 40 cases were reported all over the world. The clinical manifestation of gastric AVM are asymptomatic massive upper gastrointestinal bleeding or chronic iron deficiency anemia, The diagnosis of gastric AVM is difficult because of nonspecific findings using an endoscopy. This lesion is easily detected using a selective angiography. Furthermore, the therapeutic embolization of the feeding artery have a better chance for stopping the bleeding. In this paper we are reporting one case of gastric AV malformation, wherein rnassive UGI bleeding and dingnosis was made usmg a selective angiography. A review of literatmes was conducted to make this report possible. (Korean J Gastrointeist Endosc 18: 369-372, 1998)
