[Angiographic diagnosis and management of bleeding from the digestive organs].

Gastrointestinal bleeding is recently seen less often by the angiographer. This is mainly due to advances in endoscopy, and nuclear medicine. When patients with gastrointestinal bleeding are referred, endoscopic diagnosis and therapy should be performed at first. However, when it is impossible to diagnose or to control the bleeding, angiography must be considered as soon as possible. Intra-abdominal bleeding should be diagnosed by angiography at first. In both cases, embolization is generally safe and effective depending on the advance of occlusive agents.
