[Successful Emergency Management of an Infected Thoracic Aortic Aneurysm Rupture Using a Pedicled Latissimus Dorsi Flap after Stent-graft Implantation;Report of a Case].

We report a case of ruptured mycotic thoracic aortic aneurysm treated with a pedicled latissimus dorsi flap after stent-graft implantation. The patient was a 64-year-old woman with diabetes mellitus that had developed septicemia as a result of pyelonephritis and a perinephric abscess. The patient required emergency stent-graft implantation due to rupture of an infected thoracic aortic aneurysm on hospital day 10. On hospital day 19, the abscess cavity was debrided and irrigated, and a pedicled latissimus dorsi flap was created. No recurrence of the inflammatory reaction was observed at 1 year postoperatively.
