摘要
目的研究椎动脉型颈椎病的磁共振表现,探讨其发病机制。方法椎动脉型颈椎病63例(病例组),非椎动脉型颈椎病88例(对照组),正常人67例(正常组),均行颈部磁共振成像(MRI)和椎动脉磁共振血管成像(MRA)。结果穴1雪MRA显示3组椎动脉异常分别为53例、27例和8例,差别有显著性意义(P<0.01)。穴2雪正常组椎动脉内径左侧为(3.54±0.58)mm,右侧为(3.16±0.61)mm;对照组左侧为(3.51±0.64)mm熏右侧为(3.08±0.60)mm;病例组左侧为(2.79±0.89)mm熏右侧为(2.35±0.90)mm熏较对照组和正常组减小(P<0.05)。穴3雪病例组和对照组分别有40例、14例出现钩椎关节增生硬化,两组差别有显著性意义(P<0.01)。结论MRA可以直接显示椎动脉形态及狭窄部位,MRA分型对分析病因和指导临床治疗有重要意义。
Objictive To inveatigate the pathogenesis and MRI manifestation of vertebral arterial insufficiency due to cervical spondylosis. Methods MRA ,Magnetic Resonance Angiography, of vertebral artery and MRI ,Magnetic Resonance Imaging, of cervical spine were performed in 63 cases with clinically diagnosed vertebral arterial insufficiency due to cervical spondylosis ,patient group,, 88 cases, who were diagnosed as cervical spondylosis and excluded with vertebral artery abnormality were used as control group, and 67 healthy individuals as normal group. Results ,1, MRA showed abnormalities of vertebral artery in 53, 27 and 8 cases 0f patient, control and normal groups respectively. There was a significant difference among three groups. ,2, The diameters of vertebral arteries in normal, control and patient group were ,3.54±0.58,mm,,3.51±0.64,mm,,2.79±0.89,mm in left and ,3.16±0.61,mm,,3.08±0.60,mm,,2.35±0.90,mm in right respectively, the diameters of vertebral arteries in patient group were smaller than those in control and normal group ,P<0.05,. ,3, Forty cases showed hypertrophic uncinate process in patient group and 14 cases in control group ,P<0.05,. Conclusion MRA can detect the stenosis and other abnormalities of the vertebral artery and has significant value in clinical diagnosis and treatment of the disease.
