Arteria circumflexa ilium profunda
The arteria circumflexa ilium profunda (“deep artery encompassing the iliac bone ”) is in humans - besides the arteria epigastrica inferior - the only outlet from the external iliac artery ( external iliac artery ). In most other mammals, too, the artery arises from the external pelvic artery, but in predators it arises directly from the aorta .
The deep circumflex artery runs behind the inguinal ligament ( ligamentum inguinale ), embedded in a fascia covering , in the direction of the anterior upper iliac ridges ( spina iliaca anterior superior ). It pierces the inner trunk fascia ( Fascia transversalis ) and the transverse abdominal muscle ( Musculus transversus abdominis ). It then releases an ascending branch ( ramus ascendens ) that rises between the transverse and inner oblique abdominal muscle ( musculus obliquus internus abdominis ) and supplies the lateral abdominal wall ( flank ). This branch is important in operations on the flank, because increased bleeding must be expected between these muscle layers. In animals, the continuous branch of the deep circumflex artery is called the descending branch ( ramus descendens ), which runs in the knee fold towards the knee.
The deep circumflex iliac artery and its ramus anastomose in their course with a plurality of adjacent wells: lateral circumflex femoral artery , Ramus iliacus the iliolumbar artery and superior gluteal artery .
