Figure 4. Intraoperative: exploratory incision revealed a perforator (p) exactly at the two sites marked on the thermogram in Figure 3
(proximal thigh at left)
Figure 5. Intraoperative: thermogram with distal perforator clamped as in Figure 4 demonstrated virtually total anterolateral thigh flap
perfusion via the proximal perforator alone, thus the second perforator could be discarded
than one perforator will need to be retained. Certainly, if the source pedicle of the flap itself is clamped,
although the flap subjectively may appear well perfused, the corresponding thermogram will appropriately
appear cool as expected [Figure 6]. Upon completion of the microanastomoses with flap revascularization,
the flap should not only have a good appearance, but a correspondingly bright thermogram [Figure 7].
