Endoscopic and Angiographic Diagnosis and Management of a Gastric Arteriovenous Malformation

Introduction: Gastric arteriovenous malformation (AVM) is an uncommon cause of upper gastrointestinal (GI) bleeding. Methods and results: We describe a case of gastric AVM which was diagnosed endoscopically and successfully managed by endoclip application and percutaneous transarterial coil embolization. Conclusions: We propose that these two minimally invasive technologies can be used to manage AVM in the gut: endoscopic therapy to control luminal bleeding and interventional radiology to define the full extent of the malformation and to decrease arterial pressure and flow to the point that hemostasis can occur, without creating symptomatic ischemia.
