First perforating femoral artery

The first perforating artery (a. perforans prima) of deep femoral artery passes backward between the Pectineus and Adductor brevis (sometimes it perforates the latter); it then pierces the Adductor magnus close to the linea aspera. It gives branches to the Adductores brevis and magnus, Biceps femoris, and Glutæus maximus, and anastomoses with the inferior gluteal, medial and lateral femoral circumflex and second perforating arteries.
