摘要 【目的】探讨磁共振(MRI)、多层螺旋CT(MSCT)检查评估后循环缺血患者颅内椎基底动脉(IVBA)斑块特征、形态变化与患者病情程度的关系。【方法】回顾性分析2019年2月至2022年12月本院收治的90例后循环缺血患者的临床资料,根据MRI检查结果,将有梗死灶者纳入梗死组,无梗死灶但有相应症状的纳入短暂性脑缺血发作(TIA)组。分别于1周之内接受MRI、MSCT检查,比较两组患者的颅内IVBA斑块分布位置、特征、IVBA几何形态。【结果】MSCT检查结果显示,90例IVBA患者共102个斑块,其中椎动脉起始段检出斑块32个(31.37%)、基底动脉段检出斑块26个(25.49%),其次为椎动脉颅内段检出斑块23个(22.55%)。梗死组的软斑块检出率高于TIA组,硬斑块检出率低于TIA组,差异均有统计学意义(P<0.05)。梗死组基底动脉真实长度、基底动脉迂曲率、斑块面积、斑块负荷测定值大于TIA组,差异有统计学意义(P<0.05);梗死组的病灶血管腔面积小于TIA组,差异有统计学意义(P<0.05)。梗死组患者单侧椎动脉优势占比高于TIA组,两侧椎动脉等粗占比低于TIA组,差异有统计学意义(P<0.05)。【结论】后循环缺血患者颅内IVBA斑块特征、形态异常与患者发生脑梗死密切相关,MRI及MSCT检查能发现并评估患者IVBA病变。

Abstract:【Objective】To explore the relationship of disease severity with the characteristics and morphological changes of intracranial vertebrobasilar artery (IVBA) plaques in patients with posterior circulation ischemia evaluated by magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT). 【Methods】A retrospective analysis was conducted on the clinical data of 90 patients with posterior circulation ischemia admitted to our hospital from February 2019 to December 2022. Based on the MRI examination results, patients with infarction lesions were included in the infarction group, while those without infarction lesions but with corresponding symptoms were included in the TIA group. MRI and MSCT examinations were performed within one week to compare the distribution, characteristics, and geometric morphology of intracranial IVBA plaques between the two groups of patients. 【Results】The MSCT examination results showed a total of 102 plaques in 90 IVBA patients, including 32 plaques (31.37%) detected in the initial segment of vertebral artery, 26 plaques (25.49%) detected in the basilar artery segment of vertebral artery, and 23 plaques (22.55%) detected in the intracranial segment of the vertebral artery. The detection rate of soft plaques in the cerebral infarction group was higher than that in the TIA group, while the detection rate of hard plaques was lower than that in the TIA group, and the differences were statistically significant (P<0.05). The true length, tortuosity rate, plaque area, and plaque burden of the basal artery in the cerebral infarction group were greater than those in the TIA group, and the differences were statistically significant (P<0.05). The lesion vascular lumen area in the cerebral infarction group was lower than that in the TIA group, and the difference was statistically significant (P<0.05). The proportion of unilateral vertebral artery dominance in the cerebral infarction group was higher than that in the TIA group, and the proportion of equally thick vertebral arteries on both sides was lower than that in the TIA group, with statistical significance (P<0.05). 【Conclusion】The characteristics and morphological abnormalities of intracranial IVBA plaques in patients with posterior circulation ischemia are closely related to the occurrence of cerebral infarction. MRI and MSCT examinations can detect and evaluate IVBA lesions in patients.
