Abstract
Infective native arterial aneurysms and inflammatory aortic aneurysms are rare but morbid pathologies seen by vascular surgeons in the emergency setting. Presentation is not always clear, and a full workup must be obtained before adopting a management strategy. Treatment is multidisciplinary and is tailored to every case based on workup findings. Imaging with computed tomography, magnetic resonance, or with fluorodeoxyglucose-positron emission tomography aids in diagnosis and in monitoring response to treatment. Open surgery is traditionally performed for definitive management. Endovascular surgery may offer an alternative treatment in select cases with acceptable outcomes. Neither technique has been proven to be superior to the other. Physicians should consider patient's anatomy, comorbidities, life expectancy, and goals of care before selecting an approach. Long-term pharmacological treatment, with antibiotics in case of infective aneurysms and immunosuppressants in case of inflammatory aneurysms, is usually required and should be managed in collaboration with infectious disease specialists and rheumatologists.

Lauri C, Signore A, Campagna G, Aloisi F, Taurino M, Sirignano P. [ 18F]FDG Uptake in Non-Infected Endovascular Grafts: A Retrospective Study. Diagnostics (Basel) 2023; 13:diagnostics13030409. [PMID: 36766514 PMCID: PMC9914612 DOI: 10.3390/diagnostics13030409] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 11/27/2022] [Accepted: 01/21/2023] [Indexed: 01/24/2023] Open
Abstract
Purpose: After endovascular aneurysm repair (EVAR), an increased [18F]FDG uptake may be observed at PET/CT, being common to both vascular graft/endograft infection (VGEI) and sterile post-surgical inflammation. Increased non-specific metabolic activity, due to foreign body reaction, can persist for several years after surgery, thus complicating the interpretation of PET/CT studies. In this paper, we aimed to assess [18F]FDG distribution at different time-points after the implant of abdominal Endurant® endografts in patients without suspicion of infection. Methods: We retrospectively evaluated [18F]FDG/CT in 16 oncological patients who underwent abdominal aortic aneurysm exclusion with Endurant® grafts. Patients had no clinical suspicion of infection and were followed up for at least 24 months after scan. [18F]FDG PET/CT scans were interpreted using both visual and semi-quantitative analyses. Results: The time between the EVAR procedure and [18F]FDG PET/CT ranged between 1 and 36 months. All grafts showed mild and diffuse [18F]FDG uptake without a focal pattern. Mean values of SUVmax were 2.63 ± 0.48 (95% CI 2.38-2.88); for SUVmean 1.90 ± 0.33 (95% CI 1.72-2.08); for T/B ratios 1.43 ± 0.41 (95% CI 1.21-1.65). SUVmax and SUVmean were not correlated to the time elapsed from the procedure, but we observed a declining trend in T/B ratio over time. Conclusions: Endovascular implant of Endurant® grafts does not cause a significant inflammatory reaction. The evidence of faint and diffuse [18F]FDG uptake along the graft can reliably exclude an infection, even in early post-procedural phases. Therefore, in patients with a low probability of VGEI, [18F]FDG PET/CT can also be performed immediately after EVAR.

Diagnostic Performance of 18F-FDG PET/CT in Infectious and Inflammatory Diseases according to Published Meta-Analyses. CONTRAST MEDIA & MOLECULAR IMAGING 2019; 2019:3018349. [PMID: 31427907 PMCID: PMC6683817 DOI: 10.1155/2019/3018349] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2019] [Revised: 04/04/2019] [Accepted: 07/14/2019] [Indexed: 12/13/2022]
Abstract
Purpose To date, several meta-analyses have reported data about the diagnostic performance of 18F-FDG PET/CT in infectious and inflammatory diseases. This article aims to summarize the published evidence-based data about the diagnostic performance of 18F-FDG PET/CT in this setting. Methods A comprehensive computer literature search of meta-analyses published in PubMed/MEDLINE and Cochrane library database from January 2009 through December 2018 and regarding the diagnostic performance of 18F-FDG PET/CT in infectious and inflammatory diseases was carried out. This combination of key words was used: (i) “PET” OR “positron emission tomography” OR “FDG” OR “fluorodeoxyglucose” AND (ii) meta-analysis. Only records on inflammatory or infectious diseases were selected. Results The diagnostic performance of 18F-FDG PET/CT in detecting inflammatory and infectious diseases has been summarized taking into account 36 meta-analyses published in the literature. Evidence-based data demonstrated good diagnostic performance of 18F-FDG PET/CT for several inflammatory and infectious diseases, in particular cardiovascular infectious and inflammatory diseases and some musculoskeletal infections. Conclusions Evidence-based data about the diagnostic performance of 18F-FDG PET/CT in infectious and inflammatory diseases are increasing, with good diagnostic performance of this imaging method for some indications. More prospective multicenter studies and cost-effective analyses are warranted.

Abstract
Aortitis is a pathological term that refers to the inflammation of one or more layers of the aortic wall. It is associated with a wide spectrum of inflammatory diseases of infectious and non-infectious origins, and often present with vague clinical findings and non-specific laboratory results that can model other entities. As a result, aortitis may not form part of the initial workup and appropriate treatment can be delayed or missed. Therefore, imaging modalities are required to assess for inflammation and structural changes in the aorta to support or exclude the diagnosis of aortitis. This review presents current literature on the imaging modalities utilized in the diagnosis and management of aortitis, which surgeons and physicians should be familiar with for providing optimal patient care.

Abstract
OBJECTIVES To assess the detection rate of aortitis in giant cell arteritis (GCA) with fluorodeoxyglucose positron emission tomography/computed tomography (PET) and to compare the findings with CT angiography (CTA). METHODS Fifty-two GCA patients and 27 controls were included. GCA patients had a PET scan at diagnosis (35/52) or during relapse (17/52). Concomitant CTA was performed in 35/52 patients. Aortitis was defined as FDG uptake higher than the liver for PET and wall thickness≥3mm for CTA. Agreement between PET and CTA was evaluated by the kappa coefficient and Spearman correlation coefficient. RESULTS Aortitis was diagnosed using PET in 40% (14/35) of patients at diagnosis and in 0% of controls (0/27). Agreement was perfect between PET and CT at a patient-based level, and very good at a vascular segment-based level (kappa: 0.72 to 1). PET was positive in 35% (6/17) of patients scanned during GCA relapse, showing aortitis (n=4) and/or articular uptake (n=4). Discrepancies between PET and CT were observed only in relapsing GCA (n=3). Correlation between the maximum standardized uptake value and wall thickness was moderate at diagnosis (r: 0.57 to 0.7) and not statistically significant during relapse. CONCLUSIONS The detection rate of aortitis in GCA patients using PET is 40%, approximately in the range of CTA rates, suggesting that the two techniques have similar sensitivity. PET seems valuable in relapsing GCA, allowing the detection of vascular and articular activities.

Abstract
A 40-year-old man was admitted to our hospital for surgical treatment of aortic insufficiency and coronary ostial stenosis. Histopathology and serological tests revealed a syphilitic aortitis. F-FDG PET/CT was performed to assess the extent of aortitis, showing increased radiopharmaceutical uptake along the ascending aortic wall. A repeated FDG PET/CT after antibiotic therapy showed a markedly reduced uptake in the aortic wall, suggesting resolution of the infection according to clinical and serological data. This case highlights the usefulness of FDG PET/CT for the assessment of disease extent and treatment response in patients with syphilitic aortitis.
