Penile revascularization is a specialized vascular-surgical treatment option for erectile dysfunction. The 2009 International Consultation on Sexual Dysfunctions recommended that revascularization be limited to nonsmoker, nondiabetic men younger than 55 years of age with isolated stenosis of the internal pudendal artery with absence of venous leak. [1]
It is a terminal branch of the internal pudendal artery, along with the scrotal artery. It subdivides into three arteries, the bulbourethral artery, the dorsal artery of the penis and the cavernosal artery. The penile artery is susceptible to trauma. Impact to the groin causing damage to the artery may cause erectile dysfunction in young
Venous leak, also called venogenic erectile dysfunction and penile venous insufficiency, is one category of vasculogenic impotence — a cause of erectile dysfunction in males. [2] It affects all ages, being particularly awkward in young men. [ 3 ]
It passes between the crus penis [2] and the pubic symphysis [citation needed] of the pelvis to reach the dorsal surface of the corpus cavernosus penis. [2]As it pierces the perineal membrane, it (depending upon the source) passes between the two layers of the suspensory ligament of the penis, [citation needed] or pierces the lateral lamina of the suspensory ligament of penis.
In addition to a "hard flaccid" penis, patients may also experience erectile dysfunction (difficulty achieving or maintaining an erection; painful or tight erections; penis does not fill up completely when getting an erection; no morning erections; no nocturnal erections; no spontaneous erections; painful nocturnal erections), sensory changes ...
On entering the cavernous structure from the deep artery of the penis the arteries divide into branches, which are supported and enclosed by the trabeculae.Some of these arteries end in a capillary net-work, the branches of which open directly into the cavernous spaces; others assume a tendril-like appearance, and form convoluted and somewhat dilated vessels, which were named by Rosenmüller ...
The deep artery of the penis one of the terminal branches of the internal pudendal artery. [citation needed] It arises from the internal pudendal artery posterior to the inferior edge of the symphysis pubis [1] while the internal pudendal artery is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch). [citation needed]
The pudendal nerve (along with the internal pudendal artery) then re-enters the pelvic cavity through the lesser sciatic foramen into the pudendal canal. [29] The pudendal canal is a fascial compartment located in the inferior (lower) border of the obturator internus fascia lining the lateral (side) wall of the ischiorectal fossa. [30]
