BACKGROUND: Simultaneous reconstruction of composite bone and large soft-tissue defect areas is challenging for reconstructive surgeons. This study presents a microsurgical sequential chimeric flap composed of a flow-through anterolateral thigh perforator (ALTP) flap and a deep circumflex iliac artery perforator (DCIAP) chimeric flap for one-stage reconstruction of a complex tissue defect in limbs.
METHODS: A retrospective analysis was performed among patients who underwent reconstruction of bone composite and large soft-tissue defect areas in limbs using a sequential chimeric flap. A flow-through ALTP flap and a DCIAP chimeric flap were microsurgically fabricated as sequential chimeric flaps.
RESULTS: Ten patients were successfully treated with the sequential chimeric flaps. All components of the flaps survived in all patients. Primary closure of the donor site was achieved in all cases. The sizes of the flow-through ALTP flaps ranged from 16 × 6 cm to 27 × 8 cm. The size of the cutaneous portion of the DCIAP chimeric flap ranged from 11 × 4 cm to 20 × 9 cm, and bone flap sizes ranged from 1 × 3 × 2 cm to 2.5 × 8 × 3 cm. A vascular compromise was observed postoperatively in one case. Only one case suffered minor wound-edge necrosis. Mean follow-up time was 13.1 months. Most cases showed a satisfactory contour, and no fracture of transferred iliac segments occurred.
CONCLUSION: The sequential chimeric ALTP-DCIAP flap is a valuable alternative for one-stage reconstruction of composite bone and large soft-tissue defects in limbs. This approach is flexible and provides a large cutaneous area with primary closure of the donor site.
