“…The sensitivity of angiography for the diagnosis of angiodysplasia ranges from 58% to 86% and depends on whether there is active bleeding at the time of the procedure. 10 Extravasation of the contrast medium representing active bleeding can be demonstrated in only 6% to 20% of patients. 11 The angiographic signs found are densely opacified, dilated, tortuous, and slowly emptying intramural veins and a vascular tuft representing dilated mucosal venules and capillaries in the arterial phase and at the latest stage arteriovenous communication due to precapillary sphincter loss.…”

Acute nonvariceal upper gastrointestinal hemorrhage is a frequent condition associated with significant morbidity and mortality. Angiodysplasia is a common cause of bleeding in the gastrointestinal tract in the elderly. This case report discusses about a 75-year-old woman clinically stable with melena for 2 years due to arteriovenous fistula of upper mesenteric artery branches without adequate clinical and therapeutic treatment. The goal of this article is to report the safety and efficacy of superselective transcatheter arterial embolization with coils in treating lower gastrointestinal bleeding caused by angiodysplasia that was unresponsive to internal medicine treatment and enteroscopy management.
