Reconstruction of soft tissue defects caused by spinal surgery using a dorsal intercostal artery perforator flap

Abstract

Purpose: The reconstruction of defects resulting from spinal surgery poses a challenge to plastic surgeons due to the curved contour and strong skin tension of the back. Implant and metal exposure can also increase the difficulty of covering such defects. This study presents our experiences of covering defects after spinal surgery using dorsal intercostal artery perforator (DICAP) flaps.Methods: From November 2018 to August 2021, 14 patients with spinal soft tissue defects underwent DICAP flap reconstructive surgery at our department. The mean age of the patients was 54.3 years (range, 35–70 years). Age, sex, etiology, the dimensions of the defect and the flap, the site of the defect, surgical technique, and postoperative complications were recorded.Results: All flaps survived, with no major complications such as total flap necrosis. Minor complications were observed in four cases. One patient developed an infection with erythematous changes and another developed partial flap necrosis. Two patients experienced wound dehiscence. These minor complications were all resolved with conservative treatment. No additional complications occurred during the follow-up period.Conclusion: The use of DICAP flaps was successful in all cases. DICAP flaps can adequately cover defects following spinal surgery and have a low complication rate. Thus, DICAP flaps are a good choice for covering defects resulting from spinal surgery.
