Techniques for coil embolization of wide-neck cerebral aneurysms include the use of stents and temporary occlusion with compliant non-detachable balloons to safely allow dense packing of the aneurysm lumen with detachable coils. We describe the use of a new balloon device for assisting in wide-neck aneurysm coil treatment.
A single institution neuroendovascular database was accessed to identify cases in which the Ascent balloon (Codman Neurovascular, Raynham, MA, USA) was used for aneurysm coil embolization. Clinical, demographic, and angiographic data were obtained through chart review.
Eleven cerebral aneurysm cases were treated using the Ascent balloon during the first 12-month period that the new device was available at our institution. Three of the patients presented with ruptured aneurysms. All aneurysms were large (maximum diameter 6 mm or greater), with an average maximum diameter of 9.4 mm, and an average neck diameter of 5.5 mm. Complete occlusion with coil embolization (Raymond class I) was achieved in all cases. The Ascent balloon was successfully positioned across the neck of the aneurysm in nine patients.
This initial experience demonstrates the feasibility and immediate outcomes of the coaxial dual-lumen design Ascent balloon catheter used as an assistive device in coil embolization of wide-neck cerebral aneurysms. This device contributes to the growing number of assistive devices for the treatment of complex cerebral aneurysms.
宽颈脑动脉瘤的线圈栓塞技术包括使用支架和顺应性不可拆卸球囊进行临时闭塞，以安全地允许可解脱线圈对动脉瘤腔进行致密填塞。我们描述了一种新的球囊装置在宽颈动脉瘤线圈治疗中的应用。
通过查阅图表，从单一机构的神经血管数据库中确定使用 Ascent 球囊（Codman Neurovascular，雷纳姆，马萨诸塞州，美国）进行动脉瘤线圈栓塞的病例。获得了临床、人口统计学和血管造影数据。
在新设备可用于我院的第一个 12 个月期间，使用 Ascent 球囊治疗了 11 例脑动脉瘤病例。其中 3 例患者为破裂性动脉瘤。所有动脉瘤均较大（最大直径为 6mm 或更大），平均最大直径为 9.4mm，平均颈直径为 5.5mm。所有病例均通过线圈栓塞达到完全闭塞（Raymond 分级 I）。在 9 例患者中成功地将 Ascent 球囊定位在动脉瘤颈内。
这一初步经验证明了同轴双腔设计的 Ascent 球囊导管作为一种辅助装置在宽颈脑动脉瘤线圈栓塞中的可行性和即时结果。该装置有助于治疗复杂脑动脉瘤的辅助装置数量不断增加。
