Patient-specific Rehearsal Before EVAR
Objective: To assess the effect of patient-specific virtual reality rehearsal (PsR) before endovascular infrarenal aneurysm repair (EVAR) on technical performance and procedural errors. Background: Endovascular procedures, including EVAR, are executed in a complex multidisciplinary environment, often treating high-risk patients. Consequently, this may lead to patient harm and procedural ineffic...
متن کاملUsing MRI derived patient-specific flow models and flow imaging for flow diverting stent rehearsal
Background Flow diverting stents have recently been approved for use in treating vascular geometries not amenable to standard coiling or clipping. By using multiple stents, one inside another, the amount of blood passing through the stent walls can be controlled. Often, these stents must be deployed in aneurysms with tortuous vessels and complex geometries. The ability to rehearse stent deploym...
متن کاملPatient-specific finite element simulation of the insertion of guidewires during an EVAR procedure: towards clinically relevant indicators
This work presents an explicit FE method to compute the deformations of an aorto-iliac structure induced by the insertion of endovascular extra-stiff guidewires for the treatment of abdominal aneurysms. The mechanical model takes into account the nonlinear behavior of the arterial wall, the prestressing effect induced by the blood pressure and the mechanical support of the surrounding organs an...
متن کاملChoreography Rehearsal
We propose a methodology for statically predicting the possible interaction patterns of services within a given choreography. We focus on choreographies exploiting the event notification paradigm to manage service interactions. Control Flow Analysis techniques statically approximate which events can be delivered to match the choreography constraints and how the multicast groups can be optimised...
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...
