目的对偏头痛患者进行TCD和EEG检查,并对其临床意义进行比较和分析。方法对偏头痛患者进行TCD:主要检测双侧大脑中、前、后动脉的血液动力学情况;EEG:进行单、双极描记,均作睁闭眼、过度呼吸诱发试验。结果136例患者TCD检查122例显示不同程度异常,异常率达89.71%,其中105例(86.07%)患者血流速度加快,17例(13.93%)患者大脑中动脉、大脑前动脉血流速度减慢,并7例(5.74%)患者双侧大脑中动脉、大脑前动脉血流速度不对称。EEG:136例患者中EEG异常的34例(25.0%),其中轻度异常23例(67.65%),中度异常11例(32.35%),均为5～14岁患儿。结论偏头痛患者的TCD改变较为显著,多表现为血流速度的增快、减慢和不稳定及不对称,但以流速增快为主,同时大多伴有频谱形态和血流音的改变。偏头痛的EEG异常相对于TCD较低,异常表现以儿童较为明显。
Objective To investigate TCD and EEG in migraine patients and to compare and analyze their clinical significance. Methods TCD was performed on migraine patients. The hemodynamics of the bilateral anterior, middle and anterior cerebral arteries were detected. EEG: single and bipolar trauma were performed. Results TCD examination of 122 cases in 136 patients showed different degrees of abnormality and the rate of abnormality was 89.71%. The blood flow velocity was accelerated in 105 cases (86.07%) and in 17 cases (13.93%) in middle cerebral artery and anterior cerebral artery Slow, and 7 cases (5.74%) patients with bilateral middle cerebral artery, anterior cerebral artery flow velocity asymmetry. EEG: EEG abnormalities in 136 patients (34 cases, 25.0%), of which mild abnormalities in 23 cases (67.65%), moderate abnormalities in 11 cases (32.35%), were 5 to 14 years old children. Conclusions The TCD changes in migraine patients are more obvious, with the manifestation of faster, slower and unstable instability and asymmetry in the patients with migraine. However, the change of TCD is mainly accompanied by the increase of the flow rate, while most of them are accompanied by the change of spectral shape and blood flow sound. Migraine EEG abnormalities relative to low TCD, abnormal performance in children is more obvious.
