To assess the feasibility, safety, and effectiveness of the balloon-assisted technique with HyperForm balloon in the endovascular treatment of wide-necked intracranial aneurysms.
A total of 34 patients with 34 wide-necked intracranial aneurysms were treated with endovascular coil embolization using balloon-assisted technique with Hyperform balloon. Twenty-nine aneurysms (85.3%) were located in the anterior circulation. The group of patients was comprised of 16 men and 18 women, aged 33 to 72 years (mean : 60.6 years). The size of aneurysms was in the range of 2.0 to 22.0 mm (mean 5.5 mm) and one of neck was 2.0 to 11.9 mm (mean 3.8 mm). The dome to neck ratio was ranged from 0.83 to 1.43 (1.15). Sixteen patients were treated for unruptured aneurysms and the remaining 18 presented with a subarachnoid hemorrhage.
In the 34 aneurysms treated by the remodeling technique with HyperForm balloon, immediate angiographic results consisted of total occlusion in 31 cases (91.2%) and partial occlusion in three cases (8.8%). There were five procedure-related complications (14.7%), including two coil protrusions and three thromboembolisms; Except one patient, all were successfully resolved without permanent neurologic deficit. No new bleeding occurred during the follow-up. Twenty patients (59%) underwent angiographic follow-up from 2 to 33 months (mean 9.2 months) after treatment. Focal recanalization with coil compaction of the neck portion was observed in 5 cases (25%). Only one case showed major recanalization and underwent stent-assisted coil embolization.
The balloon-assisted technique with Hyperform balloon is a feasible, safe, and effective endovascular treatment of wide-necked cerebral aneurysms.
评估使用HyperForm球囊的球囊辅助技术在宽颈颅内动脉瘤血管内治疗中的可行性、安全性和有效性。
采用HyperForm球囊的球囊辅助技术对34例患有34个宽颈颅内动脉瘤的患者进行血管内弹簧圈栓塞治疗。29个动脉瘤（85.3%）位于前循环。患者组包括16名男性和18名女性，年龄33至72岁（平均：60.6岁）。动脉瘤大小在2.0至22.0毫米范围内（平均5.5毫米），颈宽为2.0至11.9毫米（平均3.8毫米）。瘤顶与瘤颈比为0.83至1.43（1.15）。16例患者治疗未破裂动脉瘤，其余18例表现为蛛网膜下腔出血。
在采用HyperForm球囊重塑技术治疗的34个动脉瘤中，即刻血管造影结果显示31例（91.2%）完全闭塞，3例（8.8%）部分闭塞。有5例（14.7%）与手术相关的并发症，包括2例弹簧圈突出和3例血栓栓塞；除1例患者外，所有并发症均成功解决，无永久性神经功能缺损。随访期间无新出血发生。20例患者（59%）在治疗后2至33个月（平均9.2个月）接受了血管造影随访。5例（25%）观察到颈部弹簧圈致密化的局灶性再通。仅1例出现主要再通并接受了支架辅助弹簧圈栓塞。
使用HyperForm球囊的球囊辅助技术是一种治疗宽颈脑动脉瘤的可行、安全且有效的血管内治疗方法。
