Diagnosis and treatment of arteriovenous malformation of gastrointestinal tract: an analysis of 8 cases

AIM: To summarize the clinical diagnosis and treatment of gastrointestinal hemorrhage induced by arteriovenous malformation of the gastrointestinal tract. METHODS: From December 1999 to January 2005, 8 patients were diagnosed with arteriovenous malformation of the gastrointestinal tract in our hospital, and their clinical data were retrospectively analyzed. RESULTS: Of the 8 patients, enteroscopy was totally performed 12 times on 5 patients due to the hemorrhage of unknown reasons, but no lesions were found. Arteriovenous malformations were confirmed in 3 casesby angiography and two by angiography integrated with intraoperative endoscopy. Blind surgeries were totally performed 5 times on 3 patients, and therapeutic embolization was successfully followed on 2 of them. One case died of severe hemorrhage. The 7 patients were in the follow up for 6-66 mo, and 1 died of cerebral apoplexy. CONCLUSION: Angiography and intraoperative endoscopy are more effective in the diagnosis of arteriovenous malformation of the gastrointestinal tract.
