Sequential chimeric free deep circumflex iliac artery bone flap and superficial circumflex iliac artery perforator flap from the same site for one-stage reconstructions of severe hand injury: A report of two cases

摘要

Two flaps, namely the free vascularized iliac bone graft supplied by the deep circumflex iliac artery (DCIA) and the superficial circumflex iliac artery perforator flap supplied by the superficial circumflex iliac artery (SCIA), can be individually harvested from a single surgical field. We report two cases treated by these free flaps for severe hand injury with large skin defect and osteomyelitis. Sequential chimeric flaps were anastomosed between the ascending branch of the DCIA and the SCIA. The advantage of this method is more freedom in the flap insetting for complex tissue defects. For this reason, this method is also excellent for cosmetic appearance. Furthermore, donor site morbidity can be minimized because the flaps are harvested from the same site.
