Current status of treatment for aortic graft infection: When should cryopreserved allografts be used?

Abstract

Aortic graft infection remains one of the most complex clinical challenges faced by vascular specialists, and is often associated with significant patient morbidity and mortality regardless of the approach used for management. The cryopreserved aortic allograft is now a commonly used in situ aortic replacement in the management of graft infection, and is preferred over rifampin-soaked prosthetic grafts. In the review, we summarize the indications for cryopreserved aortic allograft usage, as well as operative technique, clinical results, and alternative treatments. We propose the use of a novel term tertiary aortic fistula, to distinguish aortic fistulae in the setting of aortic endograft infection, a clinical entity whose natural history and best management are currently being characterized.
