Abstract
Sixty-five sites of arterial gastrointestinal hemorrhage in 63 patients were managed with transcatheter therapy. Arterial vasopressin infusion was attempted primarily for all but three sites; embolization was used in these cases and in those for whom vasopressin infusion failed to control bleeding. The results obtained suggest that this regimen, that is, primary vasopressin infusion with embolization reserved for infusion failures or contraindications, is more effective for control of arterial gastrointestinal hemorrhage than the use of either method alone. The role of primary embolization for control of this type of bleeding may need reassessment.
