Plastic-Reconstructive Treatment Algorithm for Dead Space Management Following Septic Total Hip Arthroplasty Removal: AV Loop and Two-Stage Free Myocutaneous Latissimus Dorsi Flap

Abstract

Background A 61-year-old patient presented with a right Girdlestone hip and wound dehiscence due to extensive dead space after radical debridement and septic arthroplasty removal. A two-stage reconstruction with the application of a subcutaneous autologous arterio-venous (AV) loop using an autologous vena saphena magna (VSM) interposition graft followed by a free latissimus dorsi flap was performed.

Method We decided to perform a two-stage procedure with AV loop creation in the first step and free flap transplantation seven days after it. In the first step, an AV vascular loop was prepared by transplanting the contralateral VSM interposition graft to the inguinal femoral vessels with subcutaneous passage of the venous loop. In the second step after 7 days, the wound was closed by a two-team approach. One surgical team completed the wound debridement, while the other team harvested the flap by microsurgical preparation of the thoracodorsal pedicle in the right axilla. Upon completed harvest, the flap was placed into the wound to fill the periosseous dead space, and the anastomosis was performed in an end-to-end fashion.

Result The patient remained free of infection with a well-healed flap. He was mobilized on crutches with partial weight bearing on the operated leg. A lower extremity prosthesis with pelvic support was customized.
