Solitaire ab型支架辅助栓塞颅内复杂动脉瘤的临床分析

A novel intracranial stent （Solitaire ab） in the treatment of complex intracranial aneurysms

目的 观察新型自膨式Solitaire ab型支架用于辅助栓塞颅内复杂动脉瘤的疗效和安全性.方法 广东省中医院脑血管病中心脑病三科自2009年10月至2010年11月采用Solitaire ab型血管内支架辅助弹簧圈栓塞治疗颅内复杂动脉瘤12例（13个动脉瘤）,其中支架辅助弹簧罔栓塞动脉瘤10例,单纯支架置入2例.分析患者的临床资料和疗效.结果 12例患者共置入支架14枚,所有支架均成功放置,无回收或重新定位,1例患者弹簧圈部分脱入载瘤动脉,其余患者均无手术相关并发症;完全填塞8例,近全填塞1例,部分填塞3例;痊愈9例,好转2例,死亡1例,死亡原因为恶性心律失常.结论 Solitaire ab 型支架用于辅助栓塞颅内复杂动脉瘤有较好的安全性和短期临床疗效.

Objective To observe the efficacy and safety of a novel self-expanding stent Solitaire ab in the treatment of complex intracranial aneurysms. Methods Twelve patients （13 aneurysms）, admitted to our hospital from October 2009 to November 2010, were treated with Solitaire ab stents. Ten patients were treated with stent-assisted coiling, the other 2 with stent placement alone.The clinical data and the treatment efficacy of these patients were analyzed. Results Fourteen stents were successfully deployed in 12 patients （13 aneurysms） with no recycling or re-positioning with a success rate of stent placement of 100%. Coil partly prolapsed into parent artery in 1 patient, and the others had no operation-related complications. Eight patients enjoyed completely filling, 1 near total filling and 3 partly filling. Nine patients got complete recovery, 2 partial recovery; and 1 died of malignant arrhythmia.Conclusion The use of Solitaire ab for the treatment of complex ntracranial aneurysms enjoys a good safety and short-term clinical outcome.
