支架结合弹簧圈在栓塞颅内复杂动脉瘤中的应用

目的 探讨支架结合弹簧圈在栓塞颅内复杂动脉瘤中的应用价值以及急性期使用支架的安全性.资料与方法 29例患者,32个动脉瘤.采用Neuroform支架,弹簧圈主要采用Matrix、Orbit圈,分析栓塞效果.急性期支架辅助栓塞宽颈动脉瘤20例.择期栓塞患者术前3天予以强抗血小板聚集药物,所有患者术后予强抗血小板聚集药物及5天抗凝治疗.术后复查21例.结果 所有病例栓塞操作均顺利完成,无手术并发症;除1例巨大动脉瘤为次全栓塞外,其他均致密栓塞.其中1枚支架覆盖2个动脉瘤并栓塞3例,支架辅助栓塞巨大宽颈动脉瘤3例,支架置入行二期动脉瘤颈残留弹簧圈再栓塞2例,动脉瘤常规弹簧圈栓塞后3年复发再以支架辅助栓塞1例.急症支架辅助微弹簧圈栓塞动脉瘤未发现支架内血栓形成或狭窄堵塞.复查21例中,除1例次全栓塞的巨大动脉瘤出现动脉瘤腔部分显影外,其余20例均未见动脉瘤显影.结论 支架结合不同型号弹簧圈栓塞有助于提高颅内复杂动脉瘤的治疗成功率;急性期可以使用支架,但在未行抗血小板聚集药物准备的前提下,其安全性有待进一步研究.

Stent assisted Coiling for Embolization of Complex Intracranial Aneurysms

Objective To explore success ratio and security of endovascular stent-assisted coil for embolization in complex intracranial aneurysms. Materials and Methods 29 cases with 32 aneurysms were embolized using Neuroform stent and Matrix coil and Orbit coil, 20 cases with wide necked aneurysm were treated by stent assisted coiling in acute period. Patients undergoing selective operation received anticoagulation drug 3 days before operation,all patients were received anticoagulation treatment for 5 days continuou...
