摘　　要：目的探讨孤立性眩晕患者的颅内CT动脉形态与脑灌注的相关性。方法选取2015年2月至2018年3月我院神经内科诊治的孤立性眩晕患者56例作为眩晕组,选择同期的无眩晕症状患者130例作为对照组,所有患者都给予CT血管成像(CT angiography,CTA)和CT灌注(CT perfusion,CTP)检查,记录颅内CT动脉形态、脑灌注指标并进行相关性分析。结果眩晕组颅内动脉的狭窄及变异较多见,与对照组对比有明显差异(P<0.05);在走行迂曲方面,两组对比没有明显差异(P>0.05)。眩晕组的脑灌注参数TTP、MTT与CBF值高于对照组,而CBV值比对照组低,两组对比存在明显差异(P<0.05)。在眩晕组患者中,Pearson相关分析显示颅内CT动脉形态异常与脑灌注TTP、MTT、CBF、CBV值都有显著相关性(P<0.05)。结论CTP检查有助于评估孤立性眩晕患者脑血流动力学状态,而CTA检查则可以判定颅内动脉形态,两者结合有助于孤立性眩晕的诊治。Objective To investigate the correlation between intracranial CT arterial morphology and cerebral perfusion in patients with solitary vertigo.Methods A total of 56 patients with solitary vertigo who were diagnosed and treated in the neurology department of our hospital were selected as the vertigo group from February 2015 to March 2018.And 130 patients without vertigo symptoms who were selected for CT examination at the same time were selected as the control group.All patients accepted CT angiography(CTA)and CT perfusion(CTP)scan,and intracranial CT arterial morphology and cerebral perfusion index were recorded and given correlation analysis.Results The stenosis and variation of intracranial arteries in the vertigo group were more common than those in the control group(P<0.05),there were no significant difference in the deviation compared between the two groups(P>0.05).The TTP,MTT and CBF values of cerebral perfusion parameters in the vertigo group were higher than those in the control group,and the CBV values were lower than the control group(P<0.05).In the vertigo group,Pearson correlation analysis showed that intracranial CT arterial morphological abnormalities were significantly correlated with cerebral perfusion TTP,MTT,CBF,and CBV values(P<0.05).Conclusion CTP examination helps to evaluate the cerebral hemodynamic status of patients with solitary vertigo,while CTA examination can determine the morphology of intracranial arteries.The combination of the two methods helps to the diagnosis and treatment of isolated vertigo.
