The superior gluteal veins are the numerous accompanying veins of the superior gluteal artery. The superior gluteal artery is the internal iliac artery's biggest branch division. The gluteal veins empty themselves out into the internal iliac veins either as one united unit (at the pelvis), or one at a time. The gluteal veins are classified as being the superior gluteal artery's "Vena comitans." Vena comitans describe veins that come in two. The term means "accompanying vein" in Latin. The veins take on tributaries through the gluteal region that correspond with the artery's various branches. They come into the pelvis via the greater sciatic foramen. For the most part, the veins come back together before terminating at the internal iliac vein. The superior gluteal veins are also called "Venae gluteae superiors." They are located in close proximity to the obturator nerves, which ascend out of the ventral divisions of several of the lumbar nerves. The nerves travel past the Psoas major's fibers, and then arise from near the pelvic brim.
