The progression of a cerebral aneurysm involves degenerative arterial wall remodeling. Various hemodynamic parameters are\r\nsuspected to be major mechanical factors related to the genesis and progression of vascular diseases. Flow alterations caused by\r\nthe insertion of coils and stents for interventional aneurysm treatment may affect the aneurysm embolization process. Therefore,\r\nknowledge of hemodynamic parameters may provide physicians with an advanced understanding of aneurysm progression and\r\nrupture, as well as the effectiveness of endovascular treatments. Progress in medical imaging and information technology has\r\nenabled the prediction of flow fields in the patient-specific blood vessels using computational analysis. In this paper, recent\r\ncomputational hemodynamic studies on cerebral aneurysm initiation, progress, and rupture are reviewed. State-of-the-art\r\ncomputational aneurysmal flow analyses after coiling and stenting are also summarized. We expect the computational analysis\r\nof hemodynamics in cerebral aneurysms to provide valuable information for planning and follow-up decisions for treatment.
