title: Bleeding simulated by the distal internal pudendal artery stain.
abstract: A capillary and venous phase blush in the region of the distal branches of the internal pudendal artery that simulates bleeding can sometimes be seen on arteriograms of male patients who are not bleeding. We describe five such cases. Correct identification of this pooling of contrast material is important to avoid unnecessary treatment by transcatheter embolization or by infusion of vasoactive drugs.
