摘要:

目的 探究CT灌注成像(CTP)、CT血管成像(CTA)联合血清神经元特异性烯醇化酶(NSE)对脑卒中偏瘫患者侧支循环(CC)状态及预后的评估价值。方法 选择脑卒中偏瘫患者106例,均行CTA和CTP检查,基于CTA影像分为CC良好组(67例)和CC不良组(39例);并依据治疗3个月后的改良Rankin量表(mRS)评分将患者分为预后良好组(56例)和预后不良组(50例)。采用酶联免疫吸附试验检测血清NSE水平;Pearson相关分析CC评分与CTP参数及血清NSE水平的相关性;受试者工作特征(ROC)曲线分析血清NSE对脑卒中偏瘫患者预后的评估价值;采用Kappa检验分析CTP、CTA单独及联合血清NSE评估脑卒中偏瘫患者预后与随访结果的一致性。结果 CC不良组CTP参数rCBF、rCBV低于CC良好组,rTTP、rMTT及血清NSE水平高于CC良好组(P<0.01)。CC评分与rCBF、rCBV呈正相关,与rTTP、rMTT及血清NSE水平呈负相关(P<0.05)。预后不良组rCBF、rCBV均低于预后良好组,CC不良比例、rTTP、rMTT、血清NSE水平及mRS评分高于预后良好组(P<0.01)。血清NSE单独预测脑卒中偏瘫患者预后不良的曲线下面积为0.878(95%CI:0.800~0.934),敏感度为74.00%,特异度为91.07%,与随访结果一致性较高(Kappa值=0.654,P<0.001);CTP、CTA联合血清NSE评估患者预后的敏感度为88.00%,特异度为85.71%,准确度为86.79%,与随访结果一致性较高(Kappa值=0.733,P<0.001)。结论 CTP、CTA联合血清NSE对脑卒中偏瘫患者CC状态及预后的评估价值较高。

Abstract:

Objective To investigate the value of CT perfusion imaging (CTP) and CT angiography (CTA) combined with serum neuron-specific enolase (NSE) in assessing the status and prognosis of collateral circulation (CC) in hemiplegic patients with stroke. Methods A total of 106 patients with stroke hemiplegia were selected in this study. All patients underwent CTA and CTP, and patients were classified into the good CC group (n=67) and the poor CC group (n=39) based on CTA images. Patients were also classified into the good prognostic group (n=56) and the poor prognostic group (n=50) based on modified Rankin Scale (mRS) scores after 3 months of treatment. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum NSE levels. Pearson correlation analysis was used to analyse the correlation between CC scores and CTP parameters and serum NSE levels. The receiver operating characteristic (ROC) curve was used to analyze the evaluation value of serum NSE for the prognosis of hemiplegic patients after stroke. Kappa test was used to analyse the consistency of the prognosis and follow-up results of hemiplegic stroke patients assessed by CTP and CTA alone and in combination with serum NSE. Results The CTP parameters rCBF and rCBV were lower in the poor CC group than those in the good CC group (P<0.05), and levels of rTTP, rMTT and serum NSE were higher than those in the good CC group (P<0.01). CC score was positively correlated with rCBF and rCBV, and negatively correlated with rTTP, rMTT and serum NSE levels (P<0.05). The rCBF and rCBV were lower in the poor prognosis group than those in the good prognosis group, and the proportion of poor CC, rTTP, rMTT, serum NSE level and mRS score were higher than those in the good prognosis group (P<0.01). The area under the curve of serum NSE alone for predicting poor prognosis in hemiplegic patients with stroke was 0.878 (95%CI: 0.800-0.934), with a sensitivity of 74.00% and a specificity of 91.07%, which was in good agreement with the results of the follow-up (Kappa value=0.654, P<0.001). Conclusion CTP, CTA combined with serum NSE have a relatively high evaluation value for the assessment of the CC status and prognosis of stroke patients with hemiplegia.
