Does the advantage of transcutaneous oximetry measurements in diabetic foot ulcer apply equally to free flap reconstruction?

Figure 5 Photographic findings of patient 1. A: Diabetic foot ulcer (DFU) on the left foot dorsum with necrotic tissue observed before debridement; B: One artery and two vena comitans successfully undergo end-to-end anastomosis (yellow arrow: Artery, blue arrow: Vein); C: Transcutaneous oxygen pressure measured on postoperative day (POD) 30; D: Successfully reconstructed DFU wound on POD 360.
