Abstract
Objective To investigate the feasibility and clinic outcome of the turbocharging technique in repairing large defect with free perforator flap. Methods From January 2017 to December 2018, 6 patients with defect of over length or large size were repaired with free perforator flaps, anterolateral thigh(ALT) flap in 3 cases and deep inferior epigastric artery perforator(DIEP) flap in 3 cases in Department of Hand Surgery, Ningbo No.6 Hospital. There were 4 males and 2 females, aged from 29 to 54 years old, with an average age of 41 years old.It was found that the size of the flap beyond the perforasome, while multiple perforators in the flaps were not from the same pedicle. The turbocharging technique was applied in the operation. The distal perforator of the flap was anastomosed with the proximal pedicle branch. The flap size ranged from 20 cm×8 cm to 25 cm×12 cm. The donor sites were closed directly for 3 cases and skin grafting for 3 cases. Results All the flaps survived successfully, no distal necrosis occurred. The patients were followed up for 3 to 12 months, with an average of 9 months. All flaps survived well with satisfactory appearance and pliable texture. The healing of skin graft was satisfactory in 3 cases in donor site. No graft skin contracture occurred. The donor sites closed directly in 3 cases had linear scar in donor site, no obvious contracture occurred. The flap sensation returned to S2-S3. Conclusions If the size of the flap is super long or large, beyond the perforasome, while multiple perforators in the flaps were not from the same pedicle, the application of turbocharging technique can avoid partial necrosis of the flap and improve the survival rate of the flap, which is an ideal alternative.
