Abstract
BACKGROUND: Deep sternal wound infection remains a serious complication after cardiac surgery, leading to increased morbidity, mortality, and cost. The goal of our study was to develop a standardized, reproducible method to safely cover deep sternal wounds and ensure improved healing rates.
METHODS: The study was developed as a retrospective cohort study. We included 58 patients who received standardized latissimus dorsi flap coverage of a sternum defect wound after poststernotomy mediastinitis at our institution between September 2015 and June 2017.
RESULTS: The average age of the cohort was 66.75 years, and 51.72% of patients were men. The mean hospital stay was 26.83 days. Eight patients (14.75%) died during the hospital stay due to sepsis or heart failure. The average flap size was 137.13 cm2. The mean operative time was 155 minutes. Seventy-four percent of patients developed a seroma at the donor site, which was treated conservatively with compression garments and taps, and 7% of patients developed a wound dehiscence of the donor site, which was treated conservatively with dressings. The mean follow-up time was 15 weeks. All 50 surviving patients showed complete wound healing on follow-up.
CONCLUSIONS: The latissimus dorsi pedicled flap is a safe, reproducible technique for coverage of deep sternal wounds, with few relevant perioperative complications. By setting definite parameters for the flap dissection and by ensuring a reliable blood supply, our method enables the coverage of these complex wounds by an interdisciplinary team in any cardiovascular surgical setting.
