Duplex Ultrasonography and its Use in Surveillance Post-EVAR
After endovascular aortic aneurysm repair (EVAR), patients require annual surveillance with either CT scan or duplex ultrasonography (DU). These studies should be used to identify patients who require reintervention for EVAR complications. DU, a less expensive and radiation free option, has been shown to accurately predict aneurysm sac size and endoleak. In addition, using criteria of PSV<300 c...
متن کاملSimplifying post-EVAR surveillance.
Surveillance after endovascular aneurysm repair (EVAR) is costly and a burden for the patient. Imaging is performed to detect stent-graft failure from endoleak or haemodynamic obstruction. Presently, computed tomographic angiography (CTA) is considered the gold standard for post-EVAR surveillance, as it has the potential to visualise most threats to stent-graft durability, such as migration, ki...
متن کاملDesign of a Pressure Sensor for Post-evar Surveillance
This paper introduces the design and fabrication process of a flexible pressure sensor for post-EVAR surveillance. Biocompatible flexible PDMS membranes with embedded CNTs with a conductivity of 11.43 S.m and elastic modulus of 2.42MPa are used to build a LC network for passive telemetry readout-out. The pressure sensor has a modelled sensitivity around 14fF/mmHg for a pressure range between 6-...
متن کاملImproving post-EVAR surveillance with a smart stent-graft
Abdominal aortic aneurysms (AAA or triple A’s) are indolent and deadly diseases. Their treatment options involve either an invasive procedure or a minimally invasive one. When the minimally invasive procedure, endovascular aneurysm repair (EVAR), was introduced, it revolutionized the treatment of AAA’s due to advantages such as shortened hospital stays and reduced costs. As EVAR requires period...
