Internal Iliac Artery

The internal iliac artery (formerly known as the hypogastric artery) is the main artery of the pelvis. The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder. It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length.
