title: Increasing the packing of small aneurysms with soft coils: an in vitro study.
abstract: The aim of this study was to determine whether or not the use of Soft and Ultra Soft Guglielmi detachable coils (GDCs) may improve the packing of cerebral aneurysms. Six coiling scenarios of a silicone aneurysm model were conducted using Standard, Soft, and Ultra Soft GDCs. Coils were introduced up to the point when the adjunct of one more coil caused protrusion out of the aneurysm sac. Packing ratios (volume of coils/aneurysm volume) ranged between 30 and 55%. The highest degree of packing was achieved with the combination of Soft GDC-18 coils and Ultra Soft GDC-10 coils. There is a positive relationship between the use of Soft and Ultra Soft GDC coils and greater aneurysm filling.
