Background and Purpose: We present our experience in using the single Solitaire AB stent for small wide-neck bifurcation aneurysms (WNBAs).
Materials and Methods: During 18 months, 20 small (the largest width <10 mm) WNBAs were treated with the single Solitaire AB stent-assisted coiling. The patients were 12 women and 8 men, with a mean age of 52 years (range: 36–66 years). The mean aneurysm size was 4.2 mm (2–9 mm) and mean neck size was 3.9 mm (2–9 mm). Results at follow-up were graded as complete occlusion, neck remnant, or residual aneurysm.
Results: All 20 small WNBAs were adequately occluded after a single Solitaire AB stent placement. There were no procedural ruptures and no thromboembolic complications occurred. Two patients developed a transient neurological deficit. In 20 patients with angiographic follow-up at 6 months, 16 (80%) aneurysms remained adequately occluded. Clinical follow-up in the 20 patients revealed mRS 0–2 in all.
Conclusions: Single Solitaire AB stent-assisted coil embolization for small WNBAs was safe and effective.

单单石AB支架技术血管内治疗小宽颈分叉动脉瘤


背景和目的：我们介绍了使用单颗 Solitaire AB 支架治疗小型宽颈分叉动脉瘤 (WNBA) 的经验。
材料和方法：在 18 个月期间，20 个小型（最大宽度 <10 mm）WNBA 接受了单颗 Solitaire AB 支架辅助盘绕治疗。患者为 12 名女性和 8 名男性，平均年龄为 52 岁（范围：36-66 岁）。平均动脉瘤尺寸为 4.2 毫米（2-9 毫米），平均颈部尺寸为 3.9 毫米（2-9 毫米）。随访结果分为完全闭塞、颈部残余或残余动脉瘤。
结果：单次 Solitaire AB 支架置入后，所有 20 个小型 WNBA 均已充分闭塞。没有手术破裂，也没有发生血栓栓塞并发症。两名患者出现了短暂的神经功能缺损。在 6 个月时进行血管造影随访的 20 名患者中，16 个（80%）动脉瘤仍然充分闭塞。对 20 名患者的临床随访显示，mRS 均为 0-2。
结论：单 Solitaire AB 支架辅助弹簧圈栓塞治疗小型 WNBA 是安全有效的。
