目的

探讨脑电图参数联合炎症指数对急性缺血性卒中前循环大血管闭塞(AIS-LVO)术后脑水肿的预测价值。

方法

选取邯郸市中心医院功能科自2022年10月至2023年12月收治的120例AIS-LVO患者为研究对象,根据机械取栓术后是否发生脑水肿分为脑水肿组和非脑水肿组。收集并比较2组患者的临床资料。所有患者均采用数字化脑电图监测系统行定量脑电图检查,记录并计算脑电图慢波化比率(DTABR)、δ波/α波比值(DAR)。同时采集患者外周静脉血进行实验室生化指标检测,计算系统性免疫炎症指数(SII)、C反应蛋白-白蛋白-淋巴细胞指数(CALLY指数)。采用多因素Logistic回归模型筛选AIS-LVO患者机械取栓术后脑水肿发生的独立影响因素,并基于独立影响因素构建术后脑水肿风险列线图预测模型,综合评估该模型的拟合优度及临床预测效能。

结果

本组患者中脑水肿组55例和非脑水肿组65例。2组患者的侧支循环优良情况、SII、CALLY指数、定量脑电图参数比较,差异均有统计学意义(P<0.05)。多因素Logistic回归分析显示,SII、DTABR、DAR是影响AIS-LVO患者机械取栓术后脑水肿的独立危险因素,CALLY指数则是其独立保护因素(P<0.05)。基于上述4项独立影响因素构建术后脑水肿风险列线图预测模型,内部验证显示模型拟合效果良好,其受试者工作特征曲线下面积为0.871(95%CI:0.812~0.917,P<0.05),模型灵敏度为93.02%,特异度为72.52%,约登指数为0.628,提示该列线图模型具有良好的临床预测效能。

结论

定量脑电图参数、SII、CALLY指数是AIS-LVO患者机械取栓术后脑水肿的独立影响因素,基于此构建的风险预测模型具有较高的预测效能。

Objective

To explore the relationship between electroencephalogram (EEG) parameters combined with inflammatory index and cerebral edema after acute ischemic stroke due to anterior circulation large vessel occlusion (AIS-LVO) surgery.

Methods

A total of 120 patients with AIS-LVO admitted to Function Department of Handan Central Hospital from October 2022 to December 2023 were selected and divided into the cerebral edema group and the non-cerebral edema group according to whether cerebral edema occurred after mechanical thrombectomy. The basic data of the two groups were statistically analyzed. Quantitative EEG examinations were performed with a digital EEG monitoring system to calculate the (δ+θ)/(α+β) ratio (DTABR) and δ-to-α ratio (DAR). Blood samples were collected to measure laboratory indicators and the systemic immunoinflammatory index (SII) and C-reactive protein-albumin-lymphocyte (CALLY) index were calculated. The clinical data of the two groups were analyzed. The influencing factors of cerebral edema after mechanical thrombectomy were analyzed using the multivariate Logistic regression model. A risk nomogram was constructed based on the above influencing factors, and the model fit was verified and the predictive efficacy was evaluated.

Results

There were 55 patients in the cerebral edema group and 65 patients in the non-cerebral edema group. There were significant differences in the excellent conditions of collateral circulation, SII, CALLY index, and quantitative electroencephalogram parameters between the two groups (P<0.05). The multivariate Logistic regression model showed that SII index, DTABR, and DAR were risk factors for cerebral edema after mechanical thrombectomy in patients with AIS-LVO, while CALLY index was a protective factor (P<0.05). A nomogram prediction model for the risk of postoperative cerebral edema was constructed based on the four independent influencing factors above. Internal validation revealed favorable goodness-of-fit of the model. The area under the receiver operating characteristic curve was 0.871 (95%CI: 0.812-0.917, P<0.05). The sensitivity, specificity and Youden's index were 93.02%, 72.52% and 0.628 respectively, which demonstrated that this nomogram possessed satisfactory predictive performance for clinical application.

Conclusions

Quantitative electroencephalogram parameters and SII are risk factors for cerebral edema after mechanical thrombectomy in patients with AIS-LVO, and CALLY index is a protective factor. The risk prediction model constructed based on this has a high predictive efficacy.
