Cryopreserved aortic homograft, lifeline treatment for infected vascular prosthesis with mediastinal abscess in a re-redo case. Issue 1 (26th January 2022) - Rufa, Magdalena
Abstract: We report about a 61-year-old man who, 6 years after initial uncomplicated mitral valve repair and 3 months after treatment of a pseudo-aneurysm of the ascending aorta with a Dacron patch, was admitted in our institution with an infection of the vascular graft, which was associated with sternal osteomyelitis and purulent cutaneous fistula. In a re-redo procedure, the proximal aortic arch and the ascending aorta were replaced with a cryopreserved aortic homograft. The infected part of the sternum was resected and the defect was covered by mobilizing the mediastinal tissue and with a bilateral muscle flap. The patient was discharged 20 days after surgery. This treatment concept outlines the benefit of cryopreserved aortic homograft when faced with a complex thoracic aortic infection.
