Common iliac artery
From WikiMD's WELLNESSPEDIA
Common iliac artery is the terminal branches of the abdominal aorta.
Anatomy[edit]
The common iliac arteries are two large arteries that originate from the aortic bifurcation at the level of the fourth lumbar vertebra.
Branches[edit]
They end in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries. Bifurcation of the aorta and the right common iliac artery
Distribution[edit]
The distribution of the common iliac artery is basically the pelvis and lower limb (as the femoral artery) on the corresponding side.
Relations[edit]
- Both common iliac arteries are accompanied along their course by the two common iliac veins which lie posteriorly and to the right.
- Their terminal bifurcation is crossed anteriorly by the ureters.
- This is significant as the bifurcation of the common iliac artery is the second point of ureteric constriction.
