A: Thermal imaging of the left thigh showing the anterior lateral thigh ALT flap perforators. Note the white arrow pointing to the first rewarming perforator P1 after the cold challenge test. B: The white arrow pointing to the second rewarming perforator P2. C: Intraoperative picture of the raised ALT free flap. Intraoperatively, both P1 and P2 were found to be corresponding to the best two perforators (in terms of size and pulsatility); hence, both of them were harvested and dissected to their common origin.
