目的探讨椎基底动脉延长扩张症(VBD)临床表现与磁共振血管造影(MRA)特点,以提高对VBD的认识。方法对经徐州医学院附属淮安医院磁共振确诊的128例VBD患者的临床资料进行回顾性分析,总结其临床表现与MRA的特点。结果临床表现:临床表现多样,主要表现为:①缺血性脑血管疾病85例;②脑干脑神经压迫损害症状27例;③出血性脑血管疾病10例;④脑积水6例。MRA表现:椎基底动脉迂曲扩张,移位并压迫脑干。基底动脉直径>4.5 mm,基底动脉长度>29.5 mm,横向偏离超过基底动脉起始点到分叉之间垂直连线>10 mm。结论椎基底动脉扩张延长症临床表现多样,以脑卒中为主,致残率及致死率高,磁共振对早期诊断及早期治疗有重要意义
Objective To investigate the clinical manifestations of vertebrobasilar artery dilatation (VBD) and magnetic resonance angiography (MRA) in order to improve the understanding of VBD. Methods The clinical data of 128 cases of VBD confirmed by magnetic resonance imaging of Huai’an Hospital Affiliated to Xuzhou Medical College were retrospectively analyzed. The clinical manifestations and characteristics of MRA were summarized. Results Clinical manifestations: The clinical manifestations varied, mainly as follows: ① 85 cases of ischemic cerebrovascular disease; ② 27 cases of brainstem nerve compression damage symptoms; ③ hemorrhagic cerebrovascular disease in 10 cases; ④ hydrocephalus in 6 cases. MRA performance: Vertebrobasilar artery tortuous expansion, shift and oppression of the brainstem. Diameter of basilar artery> 4.5 mm, length of basilar artery> 29.5 mm, lateral deviation> 10 mm perpendicular to basal artery origin beyond bifurcation. Conclusions The clinical manifestation of vertebrobasilar dilatation syndrome is diverse, mainly stroke, and the morbidity and mortality are high. MRI is of great significance for early diagnosis and early treatment
