目的 探讨大脑中动脉(MCA)粥样硬化斑块与脑梗死类型的相关性。方法 收集2018年1月—2020年12月的大脑中动脉粥样硬化患者178例,根据患者的临床表现、病史及诊断将患者分为脑梗死组(77例,按梗死部位分为深穿支梗死组、皮质梗死组和分水岭梗死组)和非脑梗死组(101例)。2组患者使用高分辨率核磁共振成像法(HRMRI)检查患者的双侧MCA粥样硬化斑块的特征,包括形态、信号强度及分布位置,从而统计分析粥样斑块特征与脑梗死类型之间的关系。结果 178例患者中77例为脑梗死患者。脑梗死组患者的强化率为55/77(71.4%),无脑梗死组患者的强化率为53/101(52.5%),相比差异有统计学意义(χ2=2.575,P=0.027)。其中脑梗死组中深穿支梗死组强化率为17/23(73.9%,χ2=8.707,P=0.021),皮质梗死组的强化率为13/19(68.4%,χ2=6.244,P=0.017),分水岭梗死组的强化率为25/35(71.4%,χ2=4.963,P=0.028),较非强化相比差异均有统计学意义。结论 大脑中动脉粥样硬化斑块的特征与脑梗死类型关系密切,斑块特征可反映斑块的稳定性,HRMRI对斑块稳定性的判断可预测脑梗死的发生及梗死位置。
Objective To explore the correlation between middle cerebral artery (MCA) atherosclerotic plaque and cerebral infarction patterns. Methods From January 2018 to December 2020, 178 patients with MCA atherosclerosis were divided into cerebral infarction group (77 cases, divided into deep perforating branch infarction group, cortical infarction group and watershed infarction group according to the infarct location) and non-cerebral infarction group (101 cases) according to their clinical manifestations, medical history and diagnosis.Two groups of patients underwent high-resolution magnetic resonance imaging (HRMRI) to examine the characteristics of bilateral MCA atherosclerotic plaques, including morphology, signal intensity and distribution location, to statistically analyze the relationship between the characteristics of atherosclerotic plaque and the patterns of cerebral infarction. Results Of 178 patients, 77 patients with cerebral infarction.The enhancement rate of the cerebral infarction group was 55/77 (71.4%), and that of the non-cerebral infarction group was 53/101 (52.5%), and difference between the two group had statistical significance(χ2=2.575, P=0.027). In the cerebral infarction group, the enhancement rate of the deep perforating branch infarction group was 17/23 (73.9%,χ2=8.707, P=0.021), that of the cortical infarction group was 13/19 (68.4%,χ2=6.244, P=0.017), and that of the watershed infarction group was 25/35 (71.4%,χ2=4.963, P=0.028), and the difference was statistically significant compared with the non-enhanced group. Conclusion The characteristics of MCA atherosclerotic plaque were closely related to the patterns of cerebral infarction,and the characteristics of plaque can reflect the stability of plaque.The judgment of plaque stability by HRMRI may predict the occurrence and paterrn of cerebral infarction.
