  • Objective To explore the feasibility and clinical effects of using free thinned deep inferior epigastric artery perforator flap to repair extensive soft tissue defects in extremities. Methods From April 2010 to January 2014, 12 patients with extensive soft tissue defect in extremities after trauma, including 10 males and 2 females, aged 21 to 48 years, 6 patients with defect in the back of wrist and 6 patients with defect in ankle were admitted to the Department of Bone Microsurgery of Xi′an Honghui hospital. After debridement, the size of soft tissue defect ranged from 15.0 cm×4.5 cm to 28.0 cm×11.0 cm. The free thinned deep inferior epigastric artery perforator flap was designed, cut and transferred for reconstruction, with size of 15.0 cm×5.0 cm to 29.0 cm×12.0 cm. The flap thickness ranged from 4.0 to 6.5 cm before defatting, and was 0.6 to 0.9 cm after defatting. All the donor sites of flaps were closed directly by suturing. The flap survival and the appearance and function of flap and donor site were observed during follow-up. Results All the flaps survived smoothly after surgery. During follow-up of 10 to 42 months, the flaps showed no bloat in appearance, no further flap revision or defatting procedures were required, the distance of static 2-point discrimination was 11 to 17 mm (14.5 mm on average). The abdominal function of patients was not affected, and no postoperative abdomen hernia or ulceration was noted. Conclusions The free thinned deep inferior epigastric artery perforator flap is thin and suitable for repairing extensive soft tissue defects in extremities with very good outcomes.
