Florid hyperaemia arising in ALT free flaps harvested from old skin graft donor sites

We would like to highlight two cases of localized hyperaemia arising in antero-lateral thigh (ALT) free flaps harvested from previously healed split thickness skin graft donor sites. The vascular changes led to concerns about possible flap perfusion compromise, with the increasing popularity of the ALT free flap, we thought it's important to document this phenomenon and suggest possible aetiology.
A 52-year-old gentleman presented for management of recurrent Merkel cell carcinoma arising from his left calf. After an extensive resection, a free ALT flap was used to reconstruct the defect. The flap was based on two septocutaneous perforators, and the skin paddle was harvested from a part of a thigh which incorporated a 6-month-old healed skin graft donor site. There was no obvious discoloration of the donor site prior to raising the flap.
