fibular artery fibular artery in anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. it arises from the tibial-fibular trunk. not to be confused with perineal artery. fibular arteryposterior view of the arteries of the lower limb, showing fibular artery and its source, the tibial-fibular trunk. the perforating branch of fibular artery is also shown.cross-section through middle of leg.
