gluteal artery การใช้

• The inferior gluteal artery usually joins the anastomosis.
• It gives twigs to the muscles attached to the ischial tuberosity and anastomoses with the inferior gluteal artery.
• The superior muscular branches of the popliteal artery have clinically important anastomoses with the terminal part of the gluteal arteries.
• It is formed by the deep branch of superior gluteal artery, with ascending branches of both medial circumflex femoral arteries.
• The coccygeal branch of the inferior gluteal artery passes behind the mid-portion of the sacrospinous ligament and pierces the sacrotuberous ligament at multiple locations.
• From there, it travels posteriorly between the transversus abdominis muscle and the internal oblique muscle to anastomose with the iliolumbar artery and the superior gluteal artery.
• The main body of the inferior gluteal artery leaves the pelvis posteriorly to the upper border of the sacrospinous ligament, to follow the inferior portion of the sciatic nerve out of the greater sciatic foramen.
• The inferior gluteal artery, from a branch of the internal iliac artery, pass behind the sciatic nerve and the sacrospinous ligament and is left uncovered in a small opening above the top of the sacrospinous ligament.
• In its course it gives off branches, which enter the anterior sacral foramina; these, after supplying the contents of the sacral canal, escapes by the posterior sacral foramina, and are distributed to the muscles and skin on the dorsal surface of the sacrum, anastomosing with the gluteal arteries.
• Therefore, to create an implant-pocket, either for a gluteal prosthesis or for lipoinjection, a low-angle muscle-dissection is performed in order to avoid the risk of severing any major branch  inferior  of the gluteal artery, which travels very close to the sacrum and to the sacrotuberous ligament.
• It then descends beneath the gluteus maximus with the inferior gluteal artery, and runs down the back of the thigh beneath the fascia lata, and over the long head of the biceps femoris to the back of the knee; here it pierces the deep fascia and accompanies the small saphenous vein to about the middle of the back of the leg, its terminal twigs communicating with the sural nerve.
