Aortic Wall Inflammation in the Pathogenesis, Diagnosis and Treatment of Aortic Aneurysms

The role of inflammation in the development of aortic aneurysms is emerging, along with the potential diagnostic and therapeutical potential of this correlation. Abdominal aorta aneurysms have a strong inflammatory substrate since atherosclerosis, which is undoubtedly linked to inflammation, is also a predisposing factor to their formation. Yet, data have emerged that the development of thoracic aorta aneurysms involves several inflammatory pathways, although they were previously referred to as a non-inflammatory disease. Since aortic aneurysms are mainly asymptomatic during their clinical course until their complications—which may be lethal—serum biomarkers for their early diagnosis are a necessity. Studies highlight that inflammation molecules may have a critical role in that direction. In addition, imaging techniques that trace aortic wall inflammation are developed in order to predict aneurysm growth rates and sites vulnerable of rupture. Several anti-inflammatory agents have been also studied in animal models and clinical trials for the treatment of aortic aneurysms. This review highlights the role of inflammation in pathogenesis, diagnosis and treatment of aortic aneurysms. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
