Shear accumulation as a means for evaluating risk of thromboembolic events in novel endovascular stent graft designs

This study includes some advanced computational fluid dynamic analysis. Shear accumulation, as discussed in this report, is an important predictor of thromboembolic events with mechanical valves; thus, the parameter is of interest to the United States Food and Drug Administration. To date we believe this analysis has not been performed on stent grafts and published in a peer reviewed journal. With stent graft designs becoming more complex and the anatomic variations of patients with complex aneurysms increasing, we determined it was an important method to introduce to the community of vascular surgeons.
