摘要
目的探讨椎动脉磁共振血管成像(MRA)在眩晕患者病因诊断中的临床应用价值。方法对52例疑椎-基底动脉供血不足引起的眩晕患者进行椎动脉MRA检查,并对其影像资料进行分析。结果本组52例患者中,椎动脉MRA显示正常者14例,显示异常者38例,其中管腔闭塞3例、管腔狭小13例、局限性狭窄15例,延长迂曲或折角形成7例。此外,在17例进一步行椎动脉DSA的患者中,椎动脉DSA与MRA完全吻合者为12例,完全吻合率为70.59%。结论椎动脉MRA作为一种无创检查,能显示大部分椎动脉病变,对临床诊断和治疗椎-基底动脉供血不足有较高的临床应用价值。
Objective To investigate the clinical value of magnetic resonance angiography（MRA） of vertebral artery in etiological diagnosis of patients with vertigo.Methods A total of 52 blackout patients with vertebrobasilar insufficiency vertigo were diagnosed clinically.All the patients were examined by MRA to investigate the tracks,diameters,and stenosis locations of vertebral arteries.Results MRA positive of vertebral artery were in 38 patients,and negative in 14 patients.Among MRA positive patients,there were obstruction of vertebral artery in 3 cases,narrow lumen in 13 cases,localized stenosis in 15 cases,and circuity in 7 cases.Furthermore,some patients were also examined by digital subtraction angiography（DSA）.The full accordance of both methods in the diagnosis of thin veterbral artery was 70.59%.Conclusions As a noninvasive method,MRA was a useful tool in diagnosing vertebral artery stenosis and obstruction,and especially available for diagnosis and treatment of patients with vertebrobasilar insufficiency.
