Several studies have suggested a possible relationship between exfoliation syndrome (XFS) and abdominal aortic aneurysm (AAA). A systematic literature review was undertaken to investigate this potential association. The systematic literature review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clear definitions of XFS and AAA were used to identify eligible studies via an unrestricted search of the PubMed interface from 1979 to October 31st, 2021. After review, 876 citations were gathered and evaluated for inclusion, from which 22 articles were included. Of these 22, 16 were excluded because they did not assess the relationship between AAA and XFS or provide primary data. Ultimately, six studies were included in this literature review. Half of the studies explored AAA prevalence in a population with or without XFS, and the other half explored the opposite. Three studies supported XFS as a risk factor for the development of AAA, and the other three found this relationship to be inconclusive. This systematic review revealed inconsistent results regarding an association between AAA and XFS. A large database study including XFS and AAA patients would be useful in further determining if an association does in fact exist.
