Deep circumflex iliac artery perforator flap: a new option for reconstruction of lumbosacral defects

Abstract

Reconstruction of lower back defects is challenging. Since primary repair is often not possible to achieve, there is a need for local or regional flap transfer. This report presents a new technique of reconstruction of lumbosacral defects by deep circumflex iliac artery perforator skin flap based on a propeller flap design. A lower back scar contracture and contour deformity in a 10-year-old female patient required excision and flap reconstruction. Deep circumflex iliac artery perforator flap was marked in the groin region as an elliptical skin paddle and dissected as an island flap based on a dominant musculocutaneous perforator. Following creation of the lumbosacral defect, reconstruction was accomplished by flap rotation based on a propeller flap design around the perforator. Donor site was closed primarily in layers. Complete flap survival was noted with uneventful recovery. Revision was later performed for flap debulking and contour restoration with pleasing result at 1 year. Deep circumflex iliac artery perforator flap can be utilized for lower back defect reconstruction by means of a propeller flap design. It is offered as a new flap option for lumbosacral reconstruction. The technique allows well-vascularized tissue transfer while accomplishing primary closure of the donor site with easily hidden scar. The disadvantages include tedious dissection as well as absence of a dominant perforator in some cases. Level of Evidence: Level V, therapeutic study.
