Flow diverter, a braided fine mesh stent, is emerging as a novel device to treat wide-necked, fusiform, and giant cerebral aneurysms since these types of aneurysms are either untreatable otherwise or have high recurrence rate treated by endovascular coils. Flow diverter devices represent a major paradigm shift in the endovascular treatment of aneurysms from filling the aneurysm cavity to diverting blood flow away from aneurysm sac with parent vessel reconstruction. Due to its high flexibility, a flow diverter can be manipulated during deployment process to achieve better results; for example, an experienced neuro-interventionalist can manipulate the stent’s local metal coverage through coordinated movement of catheter pull-back, pusher advancement, and distal coil release to pack higher density for the aneurysm orifice region to divert more flow away from aneurysm, making aneurismal thrombosis quicker and easier. Pipeline embolization device is the first flow diverter approved by FDA. In this study, we investigate the flow modification of a wide-necked aneurysm by Pipeline with different packing densities.
