BACKGROUND
Hemifacial spasm (HFS) due to vertebral artery (VA) dissecting aneurysm (VADA) is rare and endovascular treatment has been performed in selected cases.
CASE DESCRIPTION
We encountered a case of HFS caused by VADA that was managed with endovascular stent placement and additional stent-in-stent placement. Therapeutic strategies and benefits based on pre- and post-treatment evaluation by 3D multifusion imaging using silent MRA were discussed.
CONCLUSION
This is the first case report of stent-in-stent placement in successful treatment of HFS caused by VADA, in which relief of neurovascular contact was demonstrated by multifusion imaging.
背景
椎动脉（VA）夹层动脉瘤（VADA）所致的半面痉挛（HFS）较为罕见，部分病例已采用血管内治疗。
病例描述
我们遇到一例由VADA引起的HFS病例，采用血管内支架置入及额外的支架套叠置入进行治疗。讨论了基于使用静音磁共振血管造影（MRA）的三维多融合成像进行治疗前和治疗后评估的治疗策略及益处。
结论
这是首例关于支架套叠置入成功治疗由VADA引起的HFS的病例报告，其中多融合成像显示神经血管接触得到缓解。
