Intracranial saccular aneurysms, if untreated, carry a high risk of morbidity and mortality from intracranial bleeding. Embolization coils are the most common treatment. We describe the periprocedural safety and performance of the initial human experience with the next generation Medina Coil System.
The Medina Coil System is a layered three-dimensional coil made from a radiopaque, shape set core wire, and shape memory alloy outer coil filaments. Nine aneurysms in five patients were selected for treatment with the Medina Coil System.
Nine aneurysms in five patients, ranging from 5 to 17 mm in size in various locations, were treated with the Medina Coil System. No procedural or periprocedural complications were encountered. Procedure times, number of coils used to treat the aneurysm, and use of adjunctive devices were much less than anticipated if conventional coil technology had been used.
The Medina Coil System is a next generation coil that combines all of the familiar and expected procedural safety and technique concepts associated with conventional coils. We found improved circumferential aneurysm filling, which may lead to improved long term outcomes, with fewer devices and faster operating times.
颅内囊状动脉瘤若不治疗，因颅内出血导致发病和死亡的风险很高。栓塞弹簧圈是最常用的治疗方法。我们描述了新一代麦地那弹簧圈系统首次应用于人体时围手术期的安全性和性能。
麦地那弹簧圈系统是一种分层三维弹簧圈，由不透射线的定型芯线和形状记忆合金外部弹簧圈细丝制成。选择5例患者的9个动脉瘤使用麦地那弹簧圈系统进行治疗。
5例患者的9个动脉瘤，大小在5至17毫米之间，位于不同部位，均使用麦地那弹簧圈系统进行了治疗。未出现手术或围手术期并发症。如果使用传统弹簧圈技术，手术时间、用于治疗动脉瘤的弹簧圈数量以及辅助装置的使用均远低于预期。
麦地那弹簧圈系统是新一代弹簧圈，结合了与传统弹簧圈相关的所有常见且预期的手术安全性和技术理念。我们发现其动脉瘤圆周填充情况有所改善，这可能会带来更好的长期效果，且使用的装置更少，手术时间更短。
