【摘要】：目的探讨脑电图慢波化比率〔(θ+δ)/(α+β)值,DTABR〕、磁共振动脉自旋标记成像(ASL)检测相对脑血流量(r CBF)对急性脑梗死预后的评估价值。方法 46例发病7 d内的急性脑梗死患者,记录入院时美国国立卫生研究院卒中量表(NIHSS)及洛桑卒中预后评分(ASTRAL),脑电监测DTABR,ASL测量梗死区即感兴趣区(ROI)的CBF-ROI及对侧镜像区(ROM)的CBF-ROM,计算CBF-ROI/CBF-ROM得到相对脑血流量(r CBF),随访发病28 d的Barthel指数(BI),分析预后与上述指标的关系,探讨预测脑梗死预后的因素。结果 46例患者中BI60分35例,≤60分11例。预后不良组的女性比例较高,梗死体积、入院NIHSS评分、ASTRLA评分、DTABR患/健侧增加,CBF、r CBF值减少。Barthel指数与入院NIHSS评分、ASTRAL评分、梗死体积、DTABR患/健侧均呈负相关(r=-0.862,P=0.000;r=-0.772,P=0.000;r=-0.520,P=0.000;r=-0.414,P=0.004),与CBF-ROI、r CBF呈正相关(r=0.331,P=0.025;r=0.538,P=0.000)。DTABR患/健侧与r CBF呈负相关(r=-0.302,P=0.044)。入院NIHSS评分、DTABR患/健侧是预测脑梗死预后的危险因素,NIHSS评分、DTABR患/健侧越高预后越差。入院NIHSS评分8分,DTABR患/健侧1.159是预测不良预后敏感度及特异性均较好的界值。结论入院NIHSS评分联合定量脑电图DTABR有助于急性脑梗死的预后评估。
[Abstract]:Objective to evaluate the value of slow wave ratio (胃 未) / (伪 尾) of electroencephalogram (EEG) in the evaluation of prognosis of acute cerebral infarction (ACI) by, DTABR), spin-labeled magnetic resonance imaging (ASL) and relative cerebral blood flow (r CBF). Methods 46 patients with acute cerebral infarction within 7 days of onset were recorded. The stroke scale (NIHSS) and Lobsang stroke prognosis score (ASTRAL),) were recorded at admission. DTABR, was monitored by electroencephalogram (EEG). CBF-ROI of (ROI) in infarcted area of immediate interest and CBF-ROM, calculation of (ROM) in contralateral mirroring area by ASL the Barthel index (BI), relative to cerebral blood flow (r CBF),) was obtained by (r CBF), follow-up for 28 days. To explore the prognostic factors of cerebral infarction by analyzing the relationship between prognosis and the above indexes. Results there were 35 cases with BI60 and 11 cases with 鈮，
