[Hypervascularization syndrome of the penis following arterialization of the dorsal penile vein for erectile impotence].
A hypervascularization syndrome following arterialization of the deep dorsal vein of the penis to amend venous erectile impotence is a rare cause of penile ulcers that has not previously been described in the dermatological literature. Arterialization is performed by installing a shunt from the inferior epigastric artery or a venous bypass from the femoral artery to the deep dorsal vein of the penis, resulting in a blockage of venous outflow and in retrograde inflow into the corpora cavernosa. Complications arise as a result of persistently elevated blood pressure in the deep venous system and the erectile tissue in 10-20% of cases and are most often linked to dilatation of the shunt: the consequences are enlargement and induration of the glans, hazard of phimosis and paraphimosis, pulsation of the penis, micturation difficulties and, ultimately, ulceration of the glans. Surgical reduction of the arterial inflow ("banding" of the shunt) is the only therapeutic procedure that reduces hypervascularization without compromising the newly gained erectile function.
