The management of aortic graft infection

A
ortic graft and endograft infection (AGI) complicates approximately 1-4% of deployments. At present,
no universally accepted case definition exists and clinical guidelines that are underpinned by high-quality
published evidence are severely lacking. There is general consensus that AGI is diagnosed by a combination of
clinical, radiological and laboratory findings. However, in the current literature, microbiological details are brief
and in a substantial number of cases there is no positive microbiology available to base targeted antimicrobial
treatment upon. Published radiological data are mainly descriptive and the utility of various new diagnostic
imaging modalities remains unclear. The fundamental tenets of management involve removal of the infected
device, revascularization and antimicrobial therapy. However, surgical explanation carries a mortality of 18-30%
and if an infected device is left in situ, mortality approaches 100% within 2 years. The best published surgical
studies are mostly large case series but there are there are no randomised controlled trials evaluating the optimum
surgical strategies. In addition, no well-designed trails of the ideal antimicrobial agents, administration route and
treatment duration have been conducted. As a consequence, diagnosis and treatment is both extremely challenging
and inconsistent, with highly variable and often poor outcomes. Amultidisciplinary model of care is essential and
this seminar is aimed at vascular surgeons, microbiologists and infectious diseases physicians. With reference
to the limited published evidence, approaches to diagnosis and treatment of AGI will be discussed. Towards
the development of evidence-based clinical guidelines, a proposed formal case definition will be presented,
providing a consistent diagnostic standard that is essential for clinical trial design and meaningful comparison
between various management strategies. In addition to highlighting areas for future research, a recently launched
an international, multicentre AGI service evaluation database will be introduced.
