title: Multiple variations in the pelvic vasculature - a case report.
abstract: A thorough knowledge of possible variations of pelvic vasculature is very useful for surgeons, gynaecologists, radiologists, urologists and orthopaedic surgeons. We report multiple vascular variations in the left half of the pelvis of an adult male cadaver. Iliolumbar artery arose from the main trunk of the internal iliac artery. Posterior division of the internal iliac artery gave two lateral sacral arteries and a superior gluteal artery. The anterior division of the internal iliac artery gave origin to superior vesical, inferior vesical, inferior gluteal and internal pudendal arteries. The internal pudendal artery gave origin to a common trunk before leaving the pelvis. The common trunk divided into middle rectal artery and deep artery of the penis. The obturator artery took origin from the inferior epigastric artery and descended downward to the pelvis and left the pelvis by passing through the obturator foramen. Most of the other veins accompanying the arteries joined to form a plexus on the superior surface of the pelvic diaphragm. This plexus condensed to form anterior and posterior divisions of the internal iliac vein. Apart from this, the posterior part of the plexus drained directly into the common iliac vein through a large unnamed vein.
