【摘要】：目的探討后循環(huán)缺血性眩暈患者椎-基底動脈形態(tài)特點。方法回顧性分析122例后循環(huán)缺血性眩暈患者與同期60名無眩暈但有腦血管病危險因素的體檢志愿者(對照組)的腦血管病相關(guān)危險因素、頸部CT血管成像及頭部MR血管成像資料,將單因素比較的陽性指標(biāo)采用多因素Logistic回歸分析,篩查后循環(huán)缺血性眩暈患者的危險因素,并將后循環(huán)缺血組患者的椎動脈狹窄程度和基底動脈迂曲程度與對照組比較。結(jié)果 (1)后循環(huán)缺血組高血壓、高脂血癥、既往卒中或短暫性腦缺血發(fā)作病史、椎動脈粥樣硬化性狹窄、椎動脈變異及基底動脈迂曲的發(fā)生率分別為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),均明顯高于對照組的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),差異均有統(tǒng)計學(xué)意義(均P0.05)。(2)椎動脈粥樣硬化性狹窄(OR=3.891,95%CI:1.721~8.800,P0.01)、椎動脈變異(OR=3.231,95%CI:1.238~8.432,P=0.017)及基底動脈迂曲(OR=2.664,95%CI:1.189~5.972,P=0.017)是后循環(huán)缺血性眩暈的獨立危險因素。后循環(huán)缺血組椎動脈狹窄程度和基底動脈迂曲程度均高于對照組,差異均有統(tǒng)計學(xué)意義(均P0.05),椎動脈優(yōu)勢在基底動脈彎曲程度≥2級與2級間差異有統(tǒng)計學(xué)意義(P0.01)。結(jié)論椎動脈粥樣硬化性狹窄、椎動脈變異及基底動脈迂曲是老年后循環(huán)缺血性眩暈的獨立危險因素,而椎動脈優(yōu)勢是基底動脈迂曲的獨立危險因素。
[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.
