The peroneal artery supplies which region angiosome?

• A. Anterior lateral ankle and lateral rear foot
• B. Medial Plantar region
• C. Heel calcaneus area
• D. Great toe plantar surface

Answer: (A)

The peroneal artery feeds the lateral portion of the leg and the lateral aspect of the foot. In angiosome mapping, its territory includes the anterior-lateral ankle and the lateral rearfoot, which is why that region is the best match for the peroneal supply. The medial plantar region is supplied by the medial plantar artery (a branch of the posterior tibial artery), not the peroneal. The heel calcaneus is primarily fed by calcaneal branches of the posterior tibial (with some contributions from others), and the great toe plantar surface is supplied by plantar arteries from the posterior tibial/dorsalis pedis networks. So the peroneal angiosome corresponds to the anterior-lateral ankle and lateral rearfoot.
