The 'deep circumflex iliac artery' (or 'deep iliac circumflex artery') is an
artery in the
pelvis that travels along the
iliac crest of the
pelvic bone.
Course
The deep circumflex iliac artery arises from the lateral aspect of the
external iliac artery nearly opposite the origin of the
inferior epigastric artery.
It ascends obliquely lateralward behind the
inguinal ligament, contained in a fibrous sheath formed by the junction of the
transversalis fascia and
iliac fascia, to the
anterior superior iliac spine, where it anastomoses with the ascending branch of the
lateral femoral circumflex artery.
It then pierces the
transversalis fascia and passes along the inner lip of the crest of the
ilium to about its middle, where it perforates the
transversus abdominis muscle, and runs backward between that muscle and the
internal oblique, to anastomose with the
iliolumbar artery and the
superior gluteal artery.
Opposite the
anterior superior spine of the
ilium it gives off a large branch, which ascends between the internal oblique and transversus abdominis muscles, supplying them, and anastomosing with the
lumbar arteries and
inferior epigastric artery.
