Where Is the Iliac Artery?
The two iliac arteries that branch off from the aorta are located near the spine's fourth and fifth lumbar vertebrae, around the hip area. (Vertebrae are the bony parts that make up the spine.) The arteries branch into two arteries called the external iliac and the hypogastric.
The external iliac artery is a branch of the iliac that supplies blood to the pelvis and legs. The hypogastric artery supplies blood to the organs in the pelvis region.
The iliac arteries can become clogged with plaque that builds up on their interior walls. The blockage causes poor circulation to the lower extremities. Blood flow can be restored through bypass surgery in which a graft is attached above and below the blockage.
