The circumflex arteries may be branches of either the femoral artery or profunda femoris artery. Follow the course of the profunda femoris artery. It passes superficial to the pectineus muscle and deep to the adductor longus muscle. Along its course it usually gives rise to four perforating branches, which pass through openings in the adductor magnus muscle to supply the structures of the posterior thigh.

Identify again the medial femoral circumflex artery and follow it course as it disappears between the adjoining borders of iliopsoas muscle and pectineus muscle. As the lateral femoral circumflex artery leaves the femoral triangle, it passes deep to the sartorius muscle and rectus femoris muscle. The circumflex branches of the femoral artery supply adjacent muscles in the region and participate in collateral circulation at the hip joint.
