It has been known that arteriovenous malformations, involving gastrointestinal tract is often found to be the bleeding, in patient who present chronic anemia with or without specific past history and family history. Clint, et al. Report.d 47 arteriovenous malformations of gastrointestinal tract. In 22 patient (45%) arteriovenous malformations were found at terminal ileum, cecum, ascending colon and hepatic flexure, and rarely it was found at jejunum, ileum, stomach and duodenum. We have found each cases of arteriovenous malformation arising from stomach and jejunum. Diagnosis was confirmed by biopsy in each cases. A case of stomach arteriovenous malformation, the patient was a 67 year old male who complained of epigastric pain, hematemesis, melena and shock. The UGI series revealed a filling defect in greater curvature of stomach and gastrofiberoscope showed pulsatile mass suspicious of arteriovenous malformation. Diagnosis was confirmed by surgery and biopsy. A case of jejunum arteriovenous malformation, the patient was a 50 year old female who com- plained of painless melena and chronic fatigue. The patient appeared anemic on physical examina- tion. Gastrofiberoscope and colonofiberoscope were negative. However angiogram showed evidence of arteriovenous malformation at branch of jejunal artery. Diagnosis was also confirmed by surgery and biopsy.
