Which artery is not a source of foot angiosomes?

• A. Posterior tibial artery
• B. Femoral artery
• C. Anterior tibial artery
• D. Peroneal artery

Answer: (B)

Foot angiosomes are the distinct regions of the foot and ankle that receive their blood supply from specific distal arteries. The arteries that directly supply these foot regions are the anterior tibial artery (dorsal aspect), the posterior tibial artery (plantar aspect), and the peroneal artery (lateral/posterior aspects via perforators). The femoral artery, while it is the main artery of the thigh and gives rise to vessels that eventually reach the leg, does not itself define a separate foot angiosome. Its role is upstream; it feeds downstream arteries that become the foot’s arteries, but it is not a direct source of a foot angiosome. Therefore, the femoral artery is not a source of foot angiosomes.
