Bilateral external and internal pudendal veins embolization treatment for venogenic erectile dysfunction.

Erectile dysfunction (ED) or impotence is estimated to affect around 20-30 million men in the United States (Rhoden et al, 2002). Vascular etiology is purported to be the most prevalent cause of ED in the elderly population, with venogenic ED being the most common subtype (Shafik et al, 2007; Rebonato et al, 2014). A patient, who developed severe venogenic ED, was referred to interventional radiology after ineffective pharmaceutical treatments. Selective embolization of bilateral external and internal pudendal veins was performed through accessing the deep dorsal vein of penis. Subsequent venogram verified successful embolization with stasis within the outflow of the deep dorsal vein of penis. Close to 6 weeks after the procedure, the patient purports to be able to achieve approximately 65% of full penile erection and complete penile erection with penile stimulation and 0.25 mL injection of alprostadil after 25 minutes.
