What causes iliac artery blockage?
Iliac artery disease is caused by the narrowing of the arteries leading to the legs. This narrowing can also be called stenosis. It is usually caused by a buildup of fat or calcium deposits called plaque. Over time, this plaque can build to a total blockage of the artery.
What part of the body is the iliac artery?

What does the common iliac artery supply?
The common iliac arteries provide the primary blood supply to the lower limbs. Each artery divides into the external and internal iliac arteries. These vessels run parallel with their venous counterparts, the internal and external iliac veins, which join to form the inferior vena cava.
Where does iliac artery become femoral?
The exit point of the external iliac arteries is lateral to the insertion point of the inguinal ligament on the pubic tubercle, approximately one-third the distance from the pubic tubercle to the anterior superior iliac spine. Distal to the inguinal ligament, the external iliac artery becomes the common femoral artery.
Where is an iliac stent placed?
When an iliac vein narrowing (stenosis) is discovered, this can be treated with placement of a stent in the vein. The stent is inserted into the compressed iliac vein by a needle stick approach in the groin.

Sometimes this paired artery is also referred to as its plural form common iliac arteries. The left and right common iliac arteries are the terminal branches of the abdominal aorta.
What is the bifurcation of the common iliac artery?
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.
What is the difference between common iliac artery and hypogastric artery?
Common iliac artery. Bifurcation of the aorta and the right common iliac artery – side view. Hypogastric artery is an old term for internal iliac artery. The common iliac arteries are two large arteries that originate from the aortic bifurcation at the level of the fourth lumbar vertebra.
Where does the ureter cross the common iliac artery?
It runs anterior to the right sympathetic trunk and to the distal part of the right common iliac vein. The ureter crosses it at the level of its division into the external and internal iliac arteries. The left common iliac artery runs lateral to the left common iliac vein and anterior to the left sympathetic trunk.
