THE ARTERIES AND VEINS OF THE LOWER EXTREMITIES
The common femoral artery is the continuation of the external iliac artery below the inguinal ligament (Fig. 1-22). The common femoral artery divides into the superficial femoral and the profunda femoris ar- teries. The profunda femoris artery is also known as the deep femoral artery. The profunda femoris ar- tery is posterior and lateral to the superficial femo- ral artery. Branches of the profunda femoris artery include numerous perforators and the medial and lateral circumflex arteries. The superficial femoral artery courses distally, passing through the adduc- tor canal. The popliteal artery is the continuation of the superficial femoral artery and courses behind the knee in the popliteal fossa. Branches of the popliteal artery include the sural and genicular arteries. Ter- minal branches of the popliteal artery include the anterior tibial, posterior tibial, and peroneal arteries (Fig. 1-23). Initially, the popliteal artery bifurcates into the anterior tibial artery and the tibial–peroneal trunk. The tibial–peroneal trunk continues for a
