Pharmacoangiographic assessment of penile arteries in patients with erectile failure.

Pudendal angiography was done before and thirty minutes after intracavernous administration of 6 mg phenoxybenzamine in 8 men in whom screening with ultrasound Doppler had revealed abnormalities of the penile blood flow. Five vessels were not visualized until phenoxybenzamine was given. Four vessels displayed marked dilatation, three had moderate and one had slight dilatation after the pharmacologic erection was provoked. The method appears to be of value to increase the quality of the angiographic examination.
