Gastric antral vascular ectasia (GAVE) is a rare but important cause of chronic gastrointestinal bleeding. Endoscopically, it has characteristic thickened red vascular folds radiating from the pylorus to the antrum. Diagnosis is made primarily by endoscopy. Histologic examination of the endoscopic mucosal biopsies may confirm the endoscopic diagnosis. Many treatment modalities of the gastric antral vascular ectasia exist. One of them, the argon plasma coagulation (APC) is an excellent therapeutic tool. Inactive argon gas is converted to ionized form by means of electrical energy. Ionized argon plasma conducts high frequency electrical energy to tissues and leads coagulation necrosis of tissues. We experienced a case of gastric antral vascular ectasia presenting melena for about one month in a 72-year-old man treated endoscopically in four sessions with argon plasma coagulation.
