Angiographic diagnosis at gastrointestinal hemorrhage

The position of angiography in the diagnosis of gastrointestinal hemorrhage is discussed on the basis of a series of 37 patients. In this series, there were angiographic signs of bleeding in 13 cases (35%). The largest group consisted of angiodysplasias. In 24 cases, angiography revealed no signs of bleeding. The cause of symptoms was discovered later in 17 of these cases. Hemorrhagic gastritis and ventricular ulcer were the main causes of bleeding in the latter group.
