External Iliac Artery

The external iliac may be longer or shorter than usual, resulting from the bifurcation of the common iliac above or below its usual point. When longer, it often takes a tortous course, making a partial loop or bend that may take it below the brim of the pelvis.

The artery may be much smaller in diameter than usual; this may be the case when the femoral or main vessel of the lower limb arises from the inferior gluteal or other branch of the internal iliac. It then often terminates in profunda femoris.

The external iliac may provide a large branch, such as the circumflex iliac or inferior epigastric, at a point higher than usual.

On occasion it gives rise to the obturator artey (1.1% of cases).

The artery may terminate as the deep femoral in cases in which the anastomoses between the inferior gluteal and popliteal are extensive.

In some cases, it gives rise to branches usually arising from the femoral, i.e., superficial external pudendal or profunda femoris.

In cases where the ischiadic artery persists as the main artery of the lower limb the external iliac is usually poorly developed.
