Abstract
A 49-Year-old male admitted to our Hospital on March 13, 1995 with a complaint of hematoemesis. Endoscopic examination revealed four gastric ulcers and one of them had a naked vessel observed in the center of an ulcer, so that hypertonic epinephrine-saline injection was performed. Projecting bleeding occurred during the endoscopic hemostatic treatment. Transcatheter arterial embolization was immediately performed and hemostatis was once controlled. But bleeding recurred and then transcatheter arterial embolization was repeated. But bleeding was occurred again and, therefore, we did an emergenct operation. The resected specimen showed edematous mucosa and ulcers. Histopathological examination of the resected specimen revealed dilated and tortuous arteries and veins in the gastric mucosa. Endoscopic hemostatic treatment might not be enough for some cases of the gastric arteriovenous malformation.
