Coil embolization is an established treatment option for those with cerebral aneurysms. Treatment often requires the use of multiple coils to occlude the aneurysm. Over time due to compaction of the coils recanalization of the aneurysm occurs and patients may require retreatment. In an effort to minimize the occurrence of retreatment we are interested in investigating the efficacy of the Penumbra Coil 400™ a coil with a larger diameter to offer superior packing of the aneurysm. The rationale behind its use is that it will offer greater packing density with fewer coils. This will result in a shorter procedure time and lower cost. This should also lead to decrease in aneurysm recurrence and retreatment. These results should be achieved without an increase in treatment complications. An analysis of the packing densities among the different coils will be conducted to determine which coil has more desirable outcomes in conjunction with treatment results procedure time and cost.
