The prevalence of intracranial aneurysms is approximately 2% with an annual rupture rate of 0.7%.
We describe our initial feasibility experience using a new double-lumen balloon catheter for single-catheter balloon-assisted coil embolization of wide-neck intracranial aneurysms.
Two patients with large wide-neck intracranial aneurysms were referred for endovascular therapy. Endovascular treatment in the form of coil embolization alone was not feasible given the angioarchitecture of the aneurysms. Balloon-assisted coil embolization was planned.
The patients underwent balloon-assisted coil embolization using the Ascent double-lumen balloon catheter (Micrus, San Jose, California). The balloon portion of the catheter was placed into the proximal neck of the aneurysm. The balloon was inflated and coil embolization performed through the inner lumen of the catheter. There were no procedural complications.
Both aneurysms were successfully coiled by using the Ascent balloon occlusion catheter. The single-catheter balloon-assisted coil embolization technique can be performed safely and effectively with the Ascent double-lumen balloon catheter.
颅内动脉瘤的患病率约为 2%，年破裂率为 0.7%。
我们描述了使用新型双腔球囊导管对宽颈颅内动脉瘤进行单导管球囊辅助弹簧圈栓塞的初步可行性经验。
两名宽颈颅内大动脉瘤患者被转介行血管内治疗。鉴于动脉瘤的血管解剖结构，单纯采用弹簧圈栓塞的血管内治疗不可行，计划进行球囊辅助弹簧圈栓塞。
患者使用 Ascent 双腔球囊导管（Micrus，圣何塞，加利福尼亚州）进行球囊辅助弹簧圈栓塞。将导管的球囊部分置于动脉瘤的近端颈部。球囊充气，通过导管的内腔进行弹簧圈栓塞。无手术并发症。
使用 Ascent 球囊闭塞导管成功对两个动脉瘤进行了弹簧圈栓塞。使用 Ascent 双腔球囊导管，单导管球囊辅助弹簧圈栓塞技术可安全有效地进行。
