Arterial anomalies of posterior leg, posterior view. A. Absence of posterior tibial artery. Compensatory enlargement of the fibular (peroneal) artery was found to occur in approximately 5% of limbs.

Arterial anomalies of posterior leg, posterior view. B. High division of popliteal artery. Along with the anterior tibial artery descending anterior to the popliteus muscle, this anomaly was found to occur in approximately 2% of limbs.
