摘要
目的探讨颅内椎动脉夹层演变为夹层动脉瘤的影像学特征。方法回顾性分析1例椎动脉夹层演变至夹层动脉瘤患者的临床及影像资料,并复习相关文献。结果患者头痛发作期间,头颅CT显示基底动脉末端动脉瘤可能,头颅磁共振血管成像显示右侧椎动脉近基底动脉汇合处动脉瘤可能,数字减影血管造影(DSA)可见右侧椎动脉线样内膜影,考虑右侧椎动脉夹层。7个月后随访时行DSA显示右侧椎动脉瘤样扩张,考虑右侧椎动脉夹层演变为夹层动脉瘤。结论虽然颅内椎动脉夹层患者临床症状好转,但是影像学显示由椎动脉夹层演变为夹层动脉瘤风险较高。所以,对于颅内椎动脉夹层患者,随访及复查是非常必要的。
Objective To explore the imaging features of vertebral artery dissection evolving into vertebral dissecting aneurysm. Methods Analyzing the clinical data and image of one patient with the intraeranial vertebral artery dissection evolving into vertebral dissecting aneurysm, and the relevant literatures were reviewed. Results During the headache, head computed tomography （CT） scan showed a possible arterial aneurysm at the end of basilar artery, the head magnetic resonance imaging （MRI） showed that there was a possible arterial aneurysm at the intersection of right vertebral artery and basilar artery.Furthermore, on the digital subtraction angiography （DSA） image, right vertebral artery had linear intima which meant right artery dissection.Seven months later, DSA image revealed an artery ectasia in right vertebral artery which was considered as the evolution from right vertebral dissection into aneurysm dissecting. Conclusions Even though the patient feel better, the risk of vertebral artery dissection evolving into dissecting aneurysm is high. Therefore, for patients with intracranial vertebral artery dissection, follow-up visit and reexamination are necessary.
