血流导向装置（FD）植入越来越多地用于传统血管内治疗和直接手术难以治疗的动脉瘤。目前，一种新的FD支架-血流导向腔内装置（FRED）进入临床实践，并有望具有更高的治疗效果。为了预测动脉瘤是否被FRED完全闭塞，我们开发了一种新的计算流体动力学（CFD）技术，使用双层多孔介质建模来模拟其特征支架支柱。该技术可用于使用术前患者特定动脉瘤几何形状评价FRED植入后动脉瘤的血流动力学变化。作者描述了采用双层多孔介质的新型CFD技术，并报告了该技术在术前使用未破裂颈内动脉前壁动脉瘤的示例性病例预测FRED植入后动脉瘤闭塞状态的潜在有用性。
Flow diverter (FD) implantation is increasingly performed for aneurysms that are difficult to treat with conventional endovascular therapy and direct surgery. Now, a new FD stent, the Flow-Redirection Endoluminal Device (FRED), enters into clinical practice and is expected to have higher therapeutic efficacy. To predict whether an aneurysm is completely occluded by FRED, we have developed a novel computational fluid dynamics (CFD) technique using dual-layer porous media modeling that simulates its characteristic stent strut. This technique may be useful to evaluate hemodynamic changes in an aneurysm after FRED implantation using the preoperative patient-specific aneurysm geometry. The authors describe the novel CFD technique with a dual-layer porous media and report the potential usefulness of the technique to predict the aneurysm-occlusion status after FRED implantation preoperatively using an illustrative case of an unruptured internal carotid artery anterior wall aneurysm.
