Total endovascular repair of the aortic arch represents a promising option for patients ineligible to open surgery. Custom-made design of stent-grafts (SG), such as the Terumo Aortic® RelayBranch device (DB), requires complex preoperative measures. Accurate SG deployment is required to avoid intraoperative or postoperative complications, which is extremely challenging in the aortic arch. In that context, our aim is to develop a computational tool able to predict SG deployment in such highly… 

Patient-specific simulation of stent-graft deployment in type B aortic dissection: model development and validation

A virtual SG deployment simulation framework was developed that incorporates patient-specific anatomical information based on pre-TEVAR CT angiographic images, details of the SG design and the mechanical properties of the stent wire, graft and dissected aorta, and suggested that pre-stress of the aortic wall and blood pressure inside the SG should be included in order to accurately predict the deformation of the deployed SG.

Predicting Rotation in Fenestrated Endovascular Aneurysm Repair Using Finite Element Analysis.

This model accurately predicts the amount of SG rotation observed during FEVAR and can be used as a preoperative planning tool within the surgical workflow and showed that increasing or decreasing the coefficients of friction (COF) between the sheath and the vessel walls would decrease the amountof rotation observed.

A new in silico EVAR methodology to predict the final state of the deployed SG after intervention and evaluate the mechanical state of vessel and SG, such as contact forces and wall stresses is presented.

Contemporary Role of Computational Analysis in Endovascular Treatment for Thoracic Aortic Disease.

The present study reviews the current literature regarding the use of computational tools for TEVAR biomechanics, highlighting their potential clinical applications and suggests that computational models may potentially be used preoperatively to predict stent graft behavior, virtually testing the optimal stent transplant sizing, deployment, and conformability, in order to provide the best endovascular treatment.
