Vascular Pedicle and Branches of Anastomotic Branch A shows a vascular pedicle (arrows) from a branch (br) from the inferior gluteal artery
descends to supply the sciatic nerve (SN) (arrow head) of BF; biceps femoris, GM; gluteus maximus muscle.
Tran, "Gluteal compartment syndrome and superior gluteal artery
injury as a result of simple hip dislocation: a case report," The Iowa Orthopaedic Journal, vol.
sup] introduced the superior gluteal artery
perforator (SGAP) flap for covering sacral pressure sores.
An arterial bleed from a distal branch of the right superior gluteal artery
was found and subsequently coiled and embolized (Fig.
This corresponds to the emergence of the superior gluteal artery
from the upper part of the greater sciatic foramen.
Junctional lesions such as the superior gluteal artery
hemorrhage can be difficult to control.
While safe and effective, SGAP, named for the use of the superior gluteal artery
perforator, is usually deforming (taking a large chunk of tissue from the buttocks flattens its usual rounded appearance), often requires follow-up surgery to reshape the buttocks, and provides surgeons with a piece of tissue whose blood vessel length often makes it difficult to connect to a vessel in the chest, Rad says.
Like the DIEP flap, the gluteal artery
perforator (GAP) flap minimizes donor-site morbidity and spares the underlying muscle.
A computed tomography (CT) angiogram revealed a false aneurysm with extravasation from the left superior gluteal artery
with a massive pelvic retroperitoneal haematoma (Fig.
Second most common has been the superficial inferior epigastric artery flap, followed by the gluteal artery
perforator flap, which Dr.

rupture following a low energy injury," BMJ Case Reports, 2012.
Furthermore, the constant branches of the inferior gluteal artery
, running distal to the piriformis tendon along the external rotators, which eventually anastomose with the deep branch of the medial circumflex artery, are protected.
It may be much smaller in diameter when the femoral artery arises from the inferior gluteal artery
or internal iliac artery.
It then traveled forwards, infero-lateral to the common trunk of internal pudendal and inferior gluteal artery
, it further coursed forwards and downwards lying over the ischio-coccygeal part of levator ani to reach the upper part of obturator foramen, running parallel and inferior to the obturator nerve.
SUMMARY: The ischiatic artery classically described as a branch of the inferior gluteal artery
, is a long and thin vessel that is related to the ischiatic nerve.
