Rupture of abdominal aortic aneurysms (AAAs) alone is the thirteenth leading cause of death in the United States. Thus, reliable AAA-rupture risk prediction is an important advancement. If repair becomes necessary, the minimally invasive technique of inserting a stent-graft (SG), commonly referred to as endovascular aneurysm repair (EVAR), is a viable option in many cases. However, postoperative complications, such as endoleaks and/or SG migration, may occur. Computational fluid-structure interaction simulations provide physical insight into the hemodynamics coupled with multi-wall mechanics' function as an assessment tool for optimal SG placement and improved device design.

支架腹主动脉瘤的流固耦合分析。

在美国，仅腹主动脉瘤破裂（AAAs）是导致死亡的第十三位。因此，可靠的AAA破裂风险预测是​​一项重要的进步。如果有必要进行修复，则在许多情况下，一种可行的选择是植入支架植入物（SG）的微创技术，通常称为血管内动脉瘤修复（EVAR）。但是，可能会发生术后并发症，例如内漏和/或SG迁移。计算流体-结构相互作用模拟提供了对血液动力学的物理洞察力，以及多壁力学功能的评估工具，可作为最佳SG放置和改进设备设计的评估工具。
