[Gastric angiodysplasia: a rare cause of bleeding from the upper digestive tract]

Two cases of bleeding gastric angiodysplasia treated with a different approach, on the basis of the endoscopic features, are reported. Arteriovenous malformations may arise from any site of the digestive tract: gastric angiodysplasia represents one of the less frequent localizations, causing 2-5% of upper gastrointestinal bleeding. Several diagnostic tools are currently available and the choice of the most appropriate therapeutic strategy depends on many features: site and number of the lesions, patient's hemodynamic conditions, endoscopic skill. Surgery is preferred only when multiple and disseminated lesions within the gastric wall occur or when endoscopic approach fails.
