[Arteriography in digestive hemorrhage].

As it appears from a review of the literature of the last decade, arteriography is important in the diagnosis and management of gastrointestinal haemorrhage but its role has to be evaluated by a multidisciplinary approach. In fact, the role of arteriography in upper gastrointestinal bleeding is often therapeutic, because diagnosis is often made by endoscopy. In lower gastrointestinal bleeding, arteriography is mainly diagnostic and its role in treatment remains limited. Controlled studies are necessary to compare transcatheter embolization with other treatments.
