Abstract
Nine embolization experiments of a silicone aneurysm model were conducted by using helical and complex-shaped coils. Coils were introduced up to the point when the adjunct of a supplementary coil caused protrusion into the parent vessel. Packing ratios (volume of coils-aneurysm volume) ranged between 31% and 38%. Optimal packing was achieved with complex-shaped coils used in a concentric fashion. The complex-shaped coils allowed a better aneurysm filling than did helical coils.
摘要
使用螺旋形和复杂形状的线圈对硅胶动脉瘤模型进行了9次栓塞实验。将线圈引入，直到辅助添加一个额外的线圈导致其突入母血管时为止。填充率（线圈体积-动脉瘤体积）在31%至38%之间。采用同心方式使用复杂形状的线圈可实现最佳填充。与螺旋形线圈相比，复杂形状的线圈能更好地填充动脉瘤。
