title: Intermittent bleeding from minute to minute in acute massive gastrointestinal hemorrhage: arteriographic demonstration.
abstract: Acute massive gastrointestinal hemorrhage can be intermittent from minute to minute. This phenomenon is documented by arteriography in three patients. Failure to demonstrate active bleeding by angiography therefore may not prove cessation of bleeding or indicate an inadequate examination.
