Small abdominal aortic aneurysms: Has anything changed so far?

The proper management of small abdominal aortic aneurysms (AAAs), namely those under the threshold of 5.5 cm in diameter, has been under investigation for years. Risk of rupture for this group of AAAs is higher than the general population, although it remains low enough not to require a repair. However, specific factors have been associated with increased expansion or rupture rate, and these factors could identify potential candidates for earlier intervention. This review aims to collect and present all available data on the development and progress of small AAAs. Moreover, recommendations on proper management are discussed as well.
