Invited commentary

Recognizing that some abdominal aortic aneurysm (AAA) endografts have a small offset between the radiopaque markers and the proximal fabric edge that may result in unintended partial renal artery coverage, the authors investigated the hemodynamic effect of this potentially adverse event. It is generally accepted that blood flow-induced low arterial wall shear forces are associated with development of atherosclerosis (wall shear force per unit wall area is wall shear stress, WSS) and that extremely high shear rates may produce thromboembolism with or without local turbulence.
