Volumetric Abdominal Aortic Aneurysm Analysis in Post EVAR Surveillance Settings.

Introduction: Early detection of abdominal aortic aneurysms (AAA) is a mainstay of diagnosis, with Endovascular aortic repair (EVAR) emerging as the primary mode of repair. Maximum diameter measurement remains central to risk assessment; however, recent studies suggest AAA volumetric analysis may be more sensitive to true size changes. We compare the utility of volume and diameter in AAA size assessment and further investigating related clinical factors.
