What causes blockage in iliac vein?
The cause of obstruction or narrowing may be due to blood clotting (thrombosis) or non-thrombotic as in May-Thurner syndrome. A deep vein thrombosis can result in complete or partial blockage, whereas narrowing is typically due to compression from the spine, or more rarely a cyst, growth, or cancer.
Are there 2 common iliac arteries?
The two branches of the common iliac arteries are the internal iliac artery, supplying the pelvic area, and the external iliac, which supplies the lower limb (Figure 5-52). The internal iliac artery supplies the caudal thigh via the caudal gluteal artery.
What are the two common iliac arteries?
You have two iliac arteries: one on the right side of the body (called the right common iliac artery) and one on the left (called the left common iliac artery).
