We evaluated prospectively the relation between packing and reopening in coiled @entity438 . Packing, defined as the ratio between the volume of inserted coils and volume of the @entity439 expressed as percentage, was calculated for 82 @entity438 treated with detachable coils. @entity439 volume was assessed from 3D angiography. Reopening of the aneurysmal lumen at the 6-month follow-up angiography was dichotomized into present or absent. We assessed whether packing above 24% protected against reopening. Twenty-three of 82 @entity439 (28%) showed reopening. Reopening was caused by compaction in 20 @entity439 and by partial @entity715 , undetected at the time of initial treatment in three @entity439 . Three of 29 @entity439 (10%) with a packing of more than 24% showed reopening. These three @entity439 contained partially intraluminal @entity715 undetected at the time of treatment. We conclude that in coiled @entity438 packing above 24% protects against reopening by compaction in non-thrombosed @entity439 . Since intraluminal @entity715 may go undetected at the time of treatment, follow-up angiography is still warranted in @entity439 with packing densities greater than 24%.
