Circumflex Fibular Artery

The circumflex fibular artery usually rises from the upper end of the posterior tibial artery (in the lower leg), but may come from the popliteal artery or even from the anterior tibial artery. It enters the fibular head of the soleus muscle, winds around the neck of the fibula, and supplies blood along the peroneal muscles which arise from the upper part of the fibula.
