A new paper “Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study” has been published in the Frontiers in Physiology Journal. The paper was written by Monica Emendi ESR 11 of the MeDiTATe project.

The abstract is as follows:

Pre-operative planning and intra-operative navigation of endovascular aneurysm repair (EVAR) are currently challenged by guidewire-induced deformations.  In this work we aim to predict the above-mentioned deformations by means of a validated finite element approach. Hence, three physical patient-specific models of increasing anatomical complexity, i.e., including the intraluminal thrombus (ILT) and calcifications, were manufactured. The numerical and experimental results were compared. A good agreement was found between the experimental and the computational studies, characterized by an increasing trend in deformations from a simplified model to a complete model (with ILT and calcifications). The presented computational approach, used in combination with tracking technology, can potentially display a continuously updated 3D anatomical map to the operator during EVAR, limiting the use of X-ray and contrast agent.
