Image characteristics of vertebrobasilar artery dissecting aneurysm and endovascular treatment

目的分析椎基底动脉夹层动脉瘤的影像学特点及血管内治疗夹层动脉瘤的方法与疗效。方法选择椎基底动脉夹层动脉瘤患者7例,均行MRI及全脑数字减影血管造影检查,诊断明确后行支架置入治疗。采用Neuroform与LEO支架。门诊及电话随访1～24个月。结果 7例患者手术均获成功,术后早期所有患者症状均有所改善,6例症状明显改善,1例术后18个月加重。结论 MRI结合全脑数字减影血管造影,有效提高了椎基底动脉夹层动脉瘤的诊断水平,采用支架置入的方法治疗夹层动脉瘤,短期内取得较好临床效果。

Objective To analyse the image characteristics of vertebrobasilar artery dissecting aneurysm and efficacy of endovascular treatment： Methods Seven patients with vertebrobasilar artery dissecting aneurysm examined by MRI and DSA were treated with neuroform or LEO stent implantation after identification. Outpatient service and telephone follow-up were performed within 1 to 24 months. Results Seven patients were successful in operation. All patients had early postoperative improvement in symptoms. Symptoms were improved in 6 cases and exacerbated in 1 case after 18 months. Conclusion Combined use of MRI and DSA improved the diagnosis of vertebrobasilar dissecting aneurysm. Method of using stenting to treat dissecting aneurysm obtained good clinical results in short term.
