The indirect branch of the sciatic artery arises from the internal
pudendal artery in male and from the superior gluteal artery in female (Table I).
Among its branches, there are the superior gluteal artery, the inferior gluteal artery and the internal pudendal artery that go out from the pelvis through the greater ischiatic foramen to the gluteal region (Moore & Dalley, 2004).
In the extrapelvic course of the inferior gluteal artery was observed that one of its branches, called ischiatic artery, is a long and thin vessel that is related to the ischiatic nerve; and that the internal pudendal artery in this region sends only muscular branches to irrigate the muscles of this region (Williams et al., 1979).
(34-39) Cutaneous necrosis may also result from direct intra-arterial injection such as of scrotal skin after pudendal artery injection.
Injection into the direct pudendal artery in groins may cause penile & scrotal ulcerations.
The anterior trunk gives superior vesical artery, inferior vesical artery, middle rectal artery, vaginal artery, obturator artery, uterine artery, internal
pudendal artery and inferior gluteal artery.
The internal
pudendal artery and its branches are the main arterial supply to the penis.
(1976) stated that the internal
pudendal artery in the rabbit (Oryctolagus cuniculus) is the continued common iliac artery.
