Which statement about the three source arteries for foot and ankle angiosomes is true?

Which statement about the three source arteries for foot and ankle angiosomes is true?

• A. They are Posterior Tibial, Anterior Tibial, and Peroneal arteries
• B. They are Popliteal, Femoral, and Sural arteries
• C. They are Dorsalis Pedis, Plantar, and Fibular arteries
• D. They are Carotid, Brachial, and Radial arteries

Answer: (A)

The three source arteries for foot and ankle angiosomes are the posterior tibial, anterior tibial, and peroneal (fibular) arteries. This set represents the main distal arteries that supply the regions of the foot and ankle: the posterior tibial travels medially and gives plantar branches to feed the sole, the anterior tibial continues onto the dorsum of the foot with the dorsalis pedis territory, and the peroneal supplies the lateral and posterior aspects of the lower leg and contributes to the lateral foot through its branches. Understanding these three sources helps explain how blood flow reaches the different surface regions of the foot and how revascularization strategies are planned to perfuse targeted areas. The other options reference arteries that are either more proximal (popliteal, femoral) or belong to the upper body (carotid, brachial, radial), or mix arteries that aren’t the primary distal-foot sources (dorsalis pedis and plantar arteries are branches of the main three).
