Endovascular therapy is developing, but not all aneurysms are completely obliterated even by using the techniques such as stent-assisted coiling or a flow diverter. To predict the aneurysm-occlusion status after stent-assisted coiling, the authors applied computational fluid dynamics (CFD) using porous media modeling to propose a new technique with the double porous media settings, one of which is a porous media setting for a coiled aneurysm and another of which is that for an intracranial stent. CFD with double porous media settings using preoperative aneurysm geometry may be useful for simulating the hemodynamic changes in intracranial aneurysms after stent-assisted coiling.
