Using the Management of Aortic Graft Infection Collaboration (MAGIC) definition, this study aimed to investigate the progression of suspected to definitively diagnosed VGEI to derive evidence based follow up recommendations and to determine the utility of routine inflammatory markers to definitively exclude VGEI and thereby minimise unnecessary high risk intervention. Methods: One hundred eighty-eight patients fulfilling MAGIC criteria for suspected or diagnosed VGEI were followed prospectively. Multidisciplinary clinical teams recorded baseline and subsequent development of new diagnostic features (clinical, radiological, and laboratory) and outcomes. Results: The duration of follow up of survivors was a median 2.9 (range 0.6 – 8.3) years. At presentation, 78 of 188 (41%) patients reached the suspected threshold, and 110 (59%) reached the definitive diagnostic threshold. During follow up, a further 46 of 78 (59%) suspected cases acquired additional criteria so that, overall, VGEI was definitively diagnosed in 156 of 188 (83%) patients. The sensitivity of C reactive protein (CRP) ≥ 2 mg/L at presentation for diagnosed VGEI was 100%, 97% for CRP ≥ 5 mg/L, and 96% for CRP ≥ 10 mg/L. In contrast, the sensitivity of abnormal total leucocyte count (≥ 11 x109/L) was 51%. Patients with initially suspected or diagnosed VGEI had similar overall survival (p = ns, log rank). Conclusion: Using the MAGIC criteria, suspected VGEI should receive a minimum of 2 years follow up, since over half progress to diagnosed VGEI within 1 year. Underscoring the importance of regular review and extensive investigation, suspected cases have indistinguishable survival from those meeting the diagnosed threshold at presentation. In this series, a normal CRP level (but not total leucocyte count) at initial presentation excluded the later diagnosis of VGEI.
