The superior gluteal artery is the largest branch of the internal iliac artery, and appears to be the continuation of the posterior division of that vessel.
It is a short artery which runs backward between the lumbosacral trunk and the first sacral nerve, and, passing out of the pelvis above the upper border of the piriformis muscle, immediately divides into a superficial and a deep branch.
Within the pelvis it gives off a few branches to the iliacus, piriformis, and obturator internus muscles, and just previous to quitting that cavity, a nutrient artery which enters the ilium.
Structure
Superficial branch
The superficial branch enters the deep surface of the gluteus maximus, and divides into numerous branches, some of which supply the muscle and anastomose with the inferior gluteal artery, while others perforate its tendinous origin, and supply the integument covering the posterior surface of the sacrum, anastomosing with the posterior branches of the lateral sacral arteries.
Deep branch
The deep branch lies under the gluteus medius and almost immediately subdivides into two.
Of these, the superior division, continuing the original course of the vessel, passes along the upper border of the gluteus minimus to the anterior superior spine of the ilium (ASIS), anastomosing with the deep iliac circumflex artery and the ascending branch of the lateral femoral circumflex artery.
The inferior division crosses the gluteus minimus obliquely to the greater trochanter, distributing branches to the gluteal muscles and anastomoses with the lateral femoral circumflex artery.
Some branches pierce the gluteus minimus and supply the hip-joint.
