Fig. 3. 35-year-old woman with flap failure.

Patient underwent reconstruction by anterolateral thigh flap after resection of tongue cancer, and flap revision surgery after 20 post-operative days due to flap failure.

A. Contrast-enhanced CT scan 6 days after operation shows fat-containing flap (arrows) with intra-flap fluid collection (long arrow) in left submandibular space and air collection (arrowhead) in left submandibular space. B. Contrast-enhanced CT scan obtained at more caudal level than (A) shows fat-containing flap (arrows) with fat infiltration. Cutaneous fistula (arrowhead) is also noted in left submandibular area.
