【摘要】：目的探讨后循环缺血性眩晕患者椎-基底动脉形态特点。方法回顾性分析122例后循环缺血性眩晕患者与同期60名无眩晕但有脑血管病危险因素的体检志愿者(对照组)的脑血管病相关危险因素、颈部CT血管成像及头部MR血管成像资料,将单因素比较的阳性指标采用多因素Logistic回归分析,筛查后循环缺血性眩晕患者的危险因素,并将后循环缺血组患者的椎动脉狭窄程度和基底动脉迂曲程度与对照组比较。结果 (1)后循环缺血组高血压、高脂血症、既往卒中或短暂性脑缺血发作病史、椎动脉粥样硬化性狭窄、椎动脉变异及基底动脉迂曲的发生率分别为59.0%(72例)、55.7%(68例)、64.8%(79例)、41.0%(50例)、28.7%(35例)及30.3%(37例),均明显高于对照组的33.3%(20例)、31.7%(19例)、35.0%(21例)、15.0%(9例)、10.0%(6例)及15.0%(9例),差异均有统计学意义(均P0.05)。(2)椎动脉粥样硬化性狭窄(OR=3.891,95%CI:1.721~8.800,P0.01)、椎动脉变异(OR=3.231,95%CI:1.238~8.432,P=0.017)及基底动脉迂曲(OR=2.664,95%CI:1.189~5.972,P=0.017)是后循环缺血性眩晕的独立危险因素。后循环缺血组椎动脉狭窄程度和基底动脉迂曲程度均高于对照组,差异均有统计学意义(均P0.05),椎动脉优势在基底动脉弯曲程度≥2级与2级间差异有统计学意义(P0.01)。结论椎动脉粥样硬化性狭窄、椎动脉变异及基底动脉迂曲是老年后循环缺血性眩晕的独立危险因素,而椎动脉优势是基底动脉迂曲的独立危险因素。
[Abstract]:Objective to investigate the morphologic characteristics of vertebrobasilar artery in patients with posterior circulation ischemic vertigo. Methods 122 patients with posterior circulation ischemic vertigo and 60 healthy volunteers with no vertigo but risk factors of cerebrovascular disease were retrospectively analyzed. The risk factors associated with cerebrovascular disease in the radiation group, Cervical CT angiography and head Mr angiography were used to screen the risk factors of post circulatory ischemic vertigo by multivariate Logistic regression analysis. The degree of vertebral artery stenosis and the degree of basilar artery twisting in the posterior circulation ischemia group were compared with those in the control group. Results 1) Hypertension, hyperlipidemia, history of stroke or transient ischemic attack in the posterior circulation ischemia group. Vertebral atherosclerotic stenosis, The incidences of vertebral artery variation and basilar artery detour were 59.00.72 cases and 64.885%, respectively, of which 68 cases were 64.810 and 79 cases were 41.050 cases. The incidence rate of vertebral artery variation and basilar artery detour was significantly higher than that in the control group of 33.30.20 cases, 31.719 cases and 35.021 cases. The difference was statistically significant (P 0.05. 0. 2) and 15. 0% in 9 cases (P 0. 05. 0. 2). The difference was statistically significant (P 0. 05. 0. 0. 0. 0. 0%). The incidence rate of vertebral artery variation and basilar artery detour was 55.70%, respectively. The difference was statistically significant (P 0. 05. 0. 0. 0. 0%, P 0. 05, P 0. 05, P 0. 05, P 0. 05). The degree of vertebral artery stenosis and basilar artery tortuosity in posterior circulation ischemia group were higher than that in control group, and the degree of vertebral artery stenosis and basilar artery detour were significantly higher in posterior circulation ischemia group than in control group, and the degree of vertebral artery stenosis and basilar artery detour in posterior circulation ischemia group were higher than that in control group, and the degree of vertebral artery stenosis and basilar artery tortuosity in posterior circulation ischemia group were higher than that in control group, and the degree of vertebral artery stenosis and basilar artery tortuosity in posterior circulation ischemia group were higher than those in control group, and the degree of vertebral artery stenosis and basilar artery detour in posterior circulation ischemia group were higher than those in control group. The differences were statistically significant (all P 0.05%, P 0.05). There was a significant difference in the degree of basilar artery curvature between grade 2 and grade 2. Conclusion there is atherosclerotic stenosis in vertebral artery. The variation of vertebral artery and the detour of basilar artery were independent risk factors of ischemic vertigo after circulation in old age, and the advantage of vertebral artery was the independent risk factor of twisting of basilar artery.
