Coil embolization is the most commonly used method in the treatment of cerebral aneurysm.In recent years, the hemodynamics research of cerebral aneurysm has been gradually deepened. CFD simulations based on medical images have great potential in the diagnosis and treatment of cerebral aneurysms.The article firstly introduces the hemodynamic parameters that affect cerebral aneurysm embolization and computational fluid dynamics methods, then compares the numerical simulation methods of coil embolized cerebral aneurysms. Most researchers adopt simplified methods, such as Newtonian blood model, rigid or nonrigid blood vessel wall, steady flow environment and equivalent simulation of coil. The results obtained by these methods are different from the results obtained by the fluid-solid coupling method, pulsatile flow, nonNewtonian flow model and real coil model. Finally, the conclusion and prospect of coil embolization in the treatment cerebral aneurysm hemodynamics are summarized.
