This study demonstrated that provocative angiography was safe and effective for localization of intermittent or occult gastrointestinal bleeding. Overall, provocative angiography had a positivity rate of 14/40 (35 %) in this study, and all cases of active bleeding induced by provocation were successfully treated without complication.

The 35 % positivity rate for active bleeding at time of provocative angiography observed in this study is consistent with experience in prior literature.
