Reconstruction of chronic radiation-induced ulcers in the chest wall using free and pedicle flaps.

[BACKGROUND AND PURPOSE] Resection of radiation-induced ulcers often causes full-thickness defects of the chest wall. We retrospectively reviewed and evaluated 17 patients to explore a method of chest wall reconstruction.

[MATERIALS AND METHODS] A total of 17 breast cancer patients with radiation-induced ulcers were included. Various type of prostheses and flaps were used, results of clinic were evaluated.

[RESULTS] Sixteen patients had full-thickness defects and one patient had only a soft tissue defect and underwent reconstruction with a pedicle latissimus dorsi (LD) myocutaneous flap. Among all 16 full-thickness defect cases, 15 patients underwent bony thoracic reconstruction using polymesh/3D-printed titanium plates or methyl methacrylate. For soft tissue reconstruction, 13 patients reconstruction using a free deep inferior epigastric perforator (DIEP) flap in combination with a contralateral transverse rectus abdominis myocutaneous (TRAM) flap, and 2 underwent pure free DIEP flap reconstruction. Among all the patients 15 healed with no complications, and 2 patients had delayed healing on the edges of the flaps.

[CONCLUSIONS] Distant pedicle or free flap can used for soft tissue defect coverage, for those severe patients with full-thickness defects and used prostheses, free deep inferior epigastric perforator flap in combination with a contralateral transverse rectus abdominis myocutaneous flap (TRAM + DIEP) would be an applicable choice.
