aortic bifurcation. The CIA is variable in length (3.5–12 cm) and in some cases it is very short, with the iliac bifurcation occurring close to the aorta. The CIA divides into the external and internal iliac arteries at the iliac bifurcation, which lies deep in the pelvis. The internal iliac artery supplies blood to the pelvis and pelvic viscera. The external iliac artery varies in length (6–12cm) and gives off the deep circumflex iliac artery and inferior epigastric artery, before becoming the common femoral artery (CFA)
at the level of the inguinal ligament. The aorta and iliac arteries lie behind the peritoneum, containing the bowel, which can make imaging of these vessels difficult due to overlying bowel gas. One branch of the CFA that can often be identified with ultrasound is the superficial epigastric artery.
The CFA divides into the deep femoral artery, also known as the profunda femoris artery, and the superficial femoral artery (SFA) at the level of the groin. The profunda femoris artery usually runs
