If subscribing to the Angiosome Concept of Endovascular Therapy, which of the six angiosomes of the foot supplies the most direct flow to this wound on the right lateral malleolus and what primary vessel does that angiosome originate from?

A. Anterior perforating; Peroneal
B. Lateral plantar; Posterior tibial
C. Dorsalis pedis; Anterior tibial
D. Calcaneal branch; Peroneal

Show Answer with Explanation

The correct answer is A. An angiosome is an anatomic unit of tissue (consisting of skin, subcutaneous tissue, fascia, muscle, and bone) fed by a source artery and drained by specific veins. Direct revascularization of source arteries supplying a target angiosome (wound area) may be more successful for complete wound healing than indirect revascularization. In the case presented, the anterior lateral malleolus angiosome is directly supplied by the anterior perforating branch of the peroneal artery and therefore would be the target artery for revascularization.
