Sensate superior gluteal artery perforator flap for reconstruction of sacrococcygeal large wound dehiscence: A case report and literature review

Abstract

The superior gluteal artery perforator (SGAP) flap is an option for the reconstruction of deep sacral defects. Since a conventional SGAP flap is not neurotized, covered ulcers have a risk of recurrence, especially when patients cannot ambulate by themselves. In ambulatory patients, the sensory presentation of reconstructed tissue assures its protection. Purpose of this report is to present a case of the use of

Successful Reconstruction of Complex Sacrococcygeal Defects Using Chimeric Perforator Propeller Flap

“…9,17 The SGAP flap is commonly used for repairing defects in the sacrococcygeal region. 1 Nevertheless, the perforator flap cannot provide abundant bulk to kill the dead space effectively because of the lack of muscle components. 18 A challenge in reconstructing this type of wound is the 3-dimensional requirement of the flap, which covers the large skin defect and obliterates the dead space in a 1-stage procedure.…”

“…However, the traditional pedicled musculocutaneous flap lacks flexibility because of a close connection between the skin flap and muscle component, making it unsuitable for repairing the complex defect where the dead space and the skin defect are at different locations 9,17 . The SGAP flap is commonly used for repairing defects in the sacrococcygeal region 1 . Nevertheless, the perforator flap cannot provide abundant bulk to kill the dead space effectively because of the lack of muscle components 18 .…”

“…Reconstruction of these types of defects requires not only a skin island for surface coverage but also well-vascularized tissue to obliterate the dead space. Perforator propeller [1][2][3] and musculocutaneous flaps 4,5 have been used to repair sacrococcygeal defects.…”
