Abstract:
Objective:To investigate the feasibility and clinical effect of the computer assisted design of the lobulated perforator flap based on the descending branch of lateral circumflex femoral artery(d-LCFA) to reconstruct the soft tissue defects of heel.Methods:From October 2014 to November 2016, a computer assisted virtual technology was used to simulate the process of pre-operative design, isolation, and harvest of d-LCFA perforating flaps. This method was used to guide the design and harvest of the flap of d-LCFA in the repair of large-area soft tissue defects of the heel in all of the 5 patients. One patient received a combine flap of the d-LCFA flap and the perforating branch of the inferior abdominal artery flap(DIEPF). Heel appearance and function were reconstructed in phase I together with the repair of the defect. Donor site was directly sutured. The recovery effect was followed-up in the clinic.Results:The 3D visualised model of the vessels in the donor area for quadriceps artery was successfully established in all 5 patients, and the design and removal of the perforating flap were successfully guided. All the 10 flaps survived successfully in 5 patients, except 1 patient had a backflow disorder at the distal end of the inferior epigastric artery perforator flap, with partial necrosis and II grafting. After 6 to 12 months of follow-up(mean, 8.7 months), the flap showed good in colour and texture, with satisfactory heel appearance. The donor site was left with a linear scar.Conclusion:Computer assisted design technology can effectively help in the design of the polyfoliate perforator flap pedicled with d-LCFA, using this technique to assist the design and repair of large area soft tissue defect of heel could reconstruct the shape of heel in phase I and restore the function of the heel to the maximum extent.
