OBJECTIVE Currently, the risk of aneurysm sac rupture after endovascular abdominal aortic aneurysm repair (EVAR) is estimated by using a group of anatomic variables. Available techniques for pressure monitoring include either direct measurement using catheter-based techniques or indirect measurement requiring implantation of a pressure sensor during(More)
Our objective was to test vibrometry as a means to measure changes in aneurysm sac pressure in an in vitro aneurysm model. Explanted porcine abdominal aortas and nitrile rubber tubes were used to model an aneurysm sac. An ultrasound beam was used to vibrate the surface of the aneurysm model. The motion generated on the surface was detected either by(More)
