Foot angiosomes originate from which arteries?

Foot angiosomes originate from which arteries?

• A. Posterior tibial artery
• B. Anterior tibial artery
• C. Peroneal artery
• D. All of the above

Answer: (D)

Foot angiosomes come from the three infrapopliteal arteries: the posterior tibial, the anterior tibial (via the dorsalis pedis on the dorsum), and the peroneal. Each artery supplies its own vascular territory within the foot, and through perforating branches and collateral connections these territories interlink to perfuse the entire foot. The posterior tibial artery primarily feeds the plantar (sole) angiosomes, the anterior tibial (via dorsalis pedis) feeds the dorsal angiosomes, and the peroneal artery provides additional blood flow to lateral and posterior aspects. Because all three arteries contribute to the foot’s perfusion, the correct understanding is that foot angiosomes originate from all of the above. This is clinically important for planning revascularization and predicting wound healing in the foot.
