Abdominal aortic aneurysms (AAAs) are life-threatening and are associated with >80% mortality when they rupture. Therefore, detecting these aneurysms before they rupture is critical. Ultrasonography is a non-invasive tool that is used for screening AAAs by measuring abdominal aorta diameter. A recent meta-analysis demonstrated the positive effects of ultrasonography. To date, aneurysm diameter is the most reliable predictor for aneurysm rupture and is used as a criterion for surgical intervention. However, some AAAs rupture at small diameters. Therefore, a better predictor for AAA rupture that is independent of aneurysm diameter is needed. Recently, an aortic wall strain examined using ultrasonography has been reported to have a potential in predicting AAA rupture. Since the introduction of endovascular aneurysm repair (EVAR), a paradigm shift has occurred in the management of AAAs. EVAR is broadly spread with the advantage of early favorable results but with concerning endoleak complications. At present, computed tomography angiography (CTA) is considered to be a gold standard for surveillance following EVAR, but it encounters some problems, such as contrast usage or radiation exposure. Ultrasonography offers an examination free from these problems and can this be an alternative to CTA. In this review article, current trends and new technologies regarding AAA assessment using ultrasonography are introduced.
