To evaluate patients with wide-necked aneurysms of the posterior circulation who underwent Solitaire AB (ev3, Inc., Irvine, CA) stent-assisted coil embolization.
Retrospective analysis of 10 patients (age range, 32-76 years; mean age, 59.1 years) with aneurysms of the basilar artery (basilar tip, n = 5; basilar trunk, n = 4; posterior cerebral artery, n = 1). Seven of the patients presented with an acute subarachnoid hemorrhage. Five aneurysms were small, 2 were large, and 3 were giant. All patients were treated by different applications (n = 14) of the Solitaire AB neurovascular remodeling device followed by a standard coiling procedure using bioactive coils.
Positioning of all Solitaire AB stents was easy and successful. No stent required retrieving and repositioning after full deployment. There were no thromboembolic complications, and no dissection/rupture or vasospasm occurred during stent placement. In all cases except 3, 100% lesion occlusion was observed after the initial treatment.
The initial technical and clinical results of Solitaire AB stent-assisted coiling of different types of wide-necked aneurysms in the posterior circulation are highly encouraging, and this technique may improve the endovascular treatment of these aneurysms.
评估接受Solitaire AB（ev3公司，加利福尼亚州欧文市）支架辅助弹簧圈栓塞治疗的后循环宽颈动脉瘤患者。
回顾性分析10例患者（年龄范围32 - 76岁；平均年龄59.1岁），这些患者患有基底动脉动脉瘤（基底动脉尖部，n = 5；基底动脉主干，n = 4；大脑后动脉，n = 1）。7例患者表现为急性蛛网膜下腔出血。5个动脉瘤较小，2个较大，3个为巨大动脉瘤。所有患者均采用不同方式（n = 14）应用Solitaire AB神经血管重塑装置，随后使用生物活性弹簧圈进行标准的弹簧圈栓塞术。
所有Solitaire AB支架的定位均轻松且成功。完全释放后，无需回收和重新定位任何支架。未发生血栓栓塞并发症，支架置入过程中未出现夹层/破裂或血管痉挛。除3例患者外，所有病例在初始治疗后均观察到病变100%闭塞。
Solitaire AB支架辅助弹簧圈栓塞后循环不同类型宽颈动脉瘤的初步技术和临床结果非常令人鼓舞，该技术可能改善这些动脉瘤的血管内治疗。
