Propeller flap for treatment of a poststernotomy sternal fistula: A case report

SummaryThe treatment of post-operative deep sternal wound infections is a real challenge for surgeons. Conservative treatment with debridement and vacuum-assisted closure (VAC) therapy is not always successful. In the most severe and chronic cases, a surgical debridement and reconstruction of the defect is mandatory.In this report, the authors present a case of a 61-year-old female patient with a chronic cutaneous fistula in the sternal region following a median sternotomy after coronary artery bypass. The patient had already undergone treatment with antibiotics, drainage of an abscess and local debridement, but the infection continued to relapse periodically. The authors decided to treat the fistula with debridement and reconstruction with a local freestyle propeller flap mobilised from the right parasternal region.ResultsThe fistula healed without any complications. There has been no relapse, and the aesthetic result is satisfactory. The scar at the donor site is acceptable with a minimum alteration to the mammary region.ConclusionsSternal fistulas after medial sternotomy are difficult to treat. The treatment method of debridement followed, in certain cases, by VAC therapy is quite controversial. A surgical procedure is sometimes necessary to speed healing. Mobilisation of a freestyle propeller flap represents a less invasive surgical approach to the treatment of sternal fistulas in cases of conservative treatment failure.
