Freestyle chimeric anterolateral and anteromedial thigh flaps based on the perforators directly arising from superficial femoral artery: an unusual finding

The anterolateral thigh (ALT) flap is a workhorse soft tissue flap. Anteromedial thigh (AMT) flap has been used as a savior flap when lateral thigh perforators are absent. ALT and AMT flaps are based on cutaneous perforators arising from the descending branch of the lateral circumflex femoral artery (LCFA), a branch of the profunda femoris artery (PFA). Here, we present a case report of a chimeric ALT and AMT flap where the perforators were directly arising from the superficial femoral artery (SFA). This case highlights an unusual origin of the vascular pedicle in the ALT and AMT flaps and promotes the freestyle perforator flap harvest theory. Level of evidence: Level V, therapeutic study.
