title = "Comparison of two techniques of endovascular coil modeling in cerebral aneurysms using CFD",
abstract = "Coiling is the most common endovascular therapy for cerebral aneurysms. In this work, the influence of coil embolization on intra-aneurysmal hemodynamics was studied using two techniques for modeling coils. The first technique represented each coil explicitly and the second one approximated the coil structure with a porous medium. CFD simulations of pre- and post-treatment conditions were compared for one anatomically realistic cerebral aneurysm model. We observed a larger decrease in time- and space-averaged velocity in the aneurysm with the explicit model (92.3%) than with the porous medium model (71.4%). The difference between the two techniques was also demonstrated using virtual contrast injection. Whereas with the explicit model there was a large decrease in the amount of contrast entering the aneurysm and an increase in washout time, these phenomena were not observed with the porous medium model.",
