Aortic Graft Infection

ACHIEVE is a prospective observational cohort and biobank study of patients with suspected or diagnosed central vascular graft or endograft infection. The study also includes patients undergoing elective central vascular graft or endograft implantation and healthy blood donor controls. Participants undergo longitudinal clinical data collection and biospecimen sampling. The study aims to characterize clinical outcomes, host immune responses, inflammatory biomarkers, pathogen-related factors, and novel microbiological diagnostic methods, including microbial cell-free DNA sequencing, in vascular graft and endograft infections.
