In-Vivo Imaging of Changes in Abdominal Aortic Aneurysm Thrombus Volume During the Cardiac Cycle

Abstract

In-vivo thrombus compressibility varied from patient to patient, and this variation was irrespective of aneurysm size, pulse pressure, and thrombus volume. This suggests that thrombus might act as a biomechanical buffer in some, while it has virtually no effect in others. Whether differences in thrombus compressibility alter the risk of rupture will be the focus of future research.
