支架辅助技术在颅内动脉瘤血管内介入栓塞中的应用

目的探讨支架辅助技术在颅内动脉瘤血管内弹簧圈栓塞中的应用。方法回顾性分析20例颅内动脉瘤病人的临床资料，共有动脉瘤22个，均应用支架辅助技术行可脱性弹簧圈栓塞术，其中采用支架前释放技术7例，支架后释放技术8例，支架半释放技术5例。结果支架释放均一次到位，成功率100％。动脉瘤致密栓塞16个，部分栓塞6个。术中发生支架内急性血栓形成1例，经动脉内溶栓后m管再通。16例术后3个月行CTA或MRA复查，动脉瘤无复发。12例术后6个月行DSA复查，9个动脉瘤致密栓塞者均无复发，3个部分栓塞者瘤颈残留部分已不显影。结论支架辅助弹簧圈栓塞可提高动脉瘤腔栓塞密度，并发挥血流导向作用，提高治疗效果。

Application of stent-assisted coil embolization for intracranial aneurysms

Objective To evaluate the application of stent-assisted coil embolization for intracranial aneurysms. Methods -Clinical data of 20 patients with 22 intracranial aneurysms were analyzed retrospectively. Embolotherapy with stent-assisted Guglielmi detachable coiling was performed in all the patients, and the technique of stent-assisted included releasing before coifing in 7 patients, releasing after coiling in 8 and semi-releasing in 5. Results All the stents were once implanted in place, and the success rate was 100%. Complete embolization was achieved in 16 aneurysms and partial embolization in 6. Acute in-stent thrombosis occurred in 1 case during operation and cured by arterial thrombolysis. CTA or MRA reexaminations were performed in 16 patients 3 months after the operation, and no aneurysm recurred. DSA reexamination was performed in 12 patients 6 months after the operation, and no aneurysm recurred in 9 aneurysms with complete embolization and the residual aneurysm neck disappeared in 3 aneurysms with partial packing. Conclusions Stent-assisted coil embolization can improve the embolization density of aneurysmal cavities, and play a guiding role for blood flow, thus enhancing the therapeutic efficacy.
