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.
本研究的目的是确定使用柔软型和超柔软型 Guglielmi 可脱卸弹簧圈（GDC）是否能改善脑动脉瘤的栓塞效果。使用标准型、柔软型和超柔软型 GDC 对一个硅树脂动脉瘤模型进行了六种弹簧圈栓塞方案。引入弹簧圈直至再增加一个弹簧圈会导致突出到动脉瘤囊外。栓塞率（弹簧圈体积/动脉瘤体积）在 30%至 55%之间。柔软型 GDC - 18 弹簧圈和超柔软型 GDC - 10 弹簧圈联合使用时实现了最高程度的栓塞。使用柔软型和超柔软型 GDC 弹簧圈与更高的动脉瘤填充率之间存在正相关关系。
