【摘要】：目的观察颈动脉狭窄支架成形术(CAS)实施前后患者定量脑电图(QEEG)功率谱的变化,探讨其在CAS实施后脑功能改善程度的评估价值。方法选取2014年1月—2015年10月滨州医学院附属医院实施CAS的颈动脉狭窄患者36例,均于CAS实施前、后进行脑电图(EEG)检查。记录EEG检查结果,测量双侧前额区(FP_1、FP_2)、中央区(C_3、C_4)、枕区(O_1、O_2)、颞区(T_3、T_4)各频段(δ㧏θ)/(α㧏β)的相对功率比值(DTABR)。结果 CAS实施前,EEG检查结果正常9例,轻度异常15例,中度异常10例,重度异常2例。CAS实施后,EEG检查结果正常12例,轻度异常17例,中度异常6例,重度异常1例。CAS实施前、后EEG检查结果比较,差异无统计学意义(Z=-1.882,P=0.060)。CAS实施前、后双侧枕区(O_1、O_2)DTABR比较,差异无统计学意义(P0.05);CAS实施后双侧前额区(FP_1、FP_2)、中央区(C_3、C_4)、颞区(T_3、T_4)DTABR均低于CAS实施前(P0.05)。结论 CAS实施前、后QEEG在前头部有明显变化,可能与颈动脉在头部血流分布特点有关。QEEG可作为评价重度颈动脉狭窄患者CAS实施前、后脑功能改善的有效参考指标之一。
[Abstract]:Objective to observe the changes of QEEGG power spectrum in patients with carotid stenosis before and after CASs, and to evaluate the value of QEGG in evaluating the degree of improvement of brain function after CAS. Methods from January 2014 to October 2015, 36 patients with carotid artery stenosis who were treated with CAS in affiliated Hospital of Binzhou Medical College were examined by electroencephalogram (EEG) before and after the implementation of CAS. The results of EEG examination were recorded, and the relative power ratio (DTABRR) of each frequency band (未? 胃 P ~ r (伪? 尾) was measured in the bilateral prefrontal region, in the central region, in the occipital area, in the O _ 1 / O _ 2 and in the temporal region _ T _ 3 / T _ 4. Results the results of CAS were normal in 9 cases, mild abnormality in 15 cases, moderate abnormality in 10 cases, severe abnormality in 2 cases. The results of CAS were normal in 12 cases, mild abnormal in 17 cases, moderate abnormal in 6 cases, severe abnormal in 1 case. After EEG, there was no significant difference before the implementation of Z-1.882P, and before the implementation of CAS. The difference was not statistically significant (P 0.05). The difference was not statistically significant in the bilateral prefrontal area (P0.05), the central region (C _ 3C _ (4), and the temporal region (T _ (3) _ (T _ 3) _ T _ (4DTAR) were lower than that before CAS implementation. Conclusion before and after the implementation of CAS, QEEG changes obviously in the anterior head, which may be related to the blood flow distribution of the carotid artery in the head. QEEG may be an effective index for evaluating the improvement of brain function in patients with severe carotid artery stenosis before and after the implementation of CAS.
