Evaluation of Aortic Stiffness (Aortic Pulse–Wave Velocity) Before and After Elective Abdominal Aortic Aneurysm Repair Procedures: A Pilot Study

摘要

Background:The main clinical criterion for abdominal aortic aneurysm (AAA) repair operations is an AAA diameter ≥5.5 cm. When AAAs increase in size, specific changes occur in the mechanical properties of the aortic wall. Pulse-wave velocity (PWV) has been used as an indicator of vascular stiffness. A low PWV may predict AAA rupture risk and is an early predictor of cardiovascular mortality.
