Patient-Specific Virtual Endovascular Treatment Model

In recent years, virtual endovascular treatment models introduced to assist endovascular interventionists in preoperatively assessing procedures’ feasibility, efficacy, and safety. The development of numerical biomechanical methods is a promising tool for accurately anticipating the interactions between tissue structures and medical devices, which could be used to evaluate potential risks and complications of a given procedure. The presented virtual endovascular treatment model introduces an efficient method that can be adjusted for patients with different anatomical and physiological features. The advantages of the current model include its capacity to recreate vascular wall deformability and the validation process of this model against real-time treatment results. The maximum vascular displacements recorded during stent deployment and after removing the delivery system were 8.20 mm and 4.80 mm, respectively. These displacements resulted from the deformation of the vascular structure during virtual treatment. The vascular deformation was observed in real-time patient procedures with a strong correlation with our results. Therefore, the current virtual endovascular treatment model is reliable with the predictability of vascular tissue deformation.
