摘要:

目的 探讨脑氧饱和度联合脑钠肽对急性缺血性脑卒中(AIS)机械取栓术后出血转化的预测价值。方法 回顾性分析接受机械取栓术治疗的120例AIS患者的临床资料。所有患者在术后24~72 h内行头颅CT检查,根据是否发生出血转化分为未出血转化组(66例)和出血转化组(54例)。比较2组患者一般资料、实验室检查结果、脑氧饱和度和血清脑钠肽水平的差异,采用受试者工作特征(ROC)曲线评估脑氧饱和度联合血清脑钠肽预测AIS患者机械取栓术后出血转化的价值,Pearson相关分析脑氧饱和度与血清脑钠肽的关系,采用多因素Logistic回归分析脑氧饱和度与血清脑钠肽对AIS患者机械取栓术后出血转化的影响。结果 出血转化组患者心房颤动、发病至入院时间、入院时美国国立卫生研究院卒中量表(NIHSS)评分和血清脑钠肽水平均高于未出血转化组(P<0.05),脑氧饱和度低于未出血转化组(P<0.05)。AIS患者脑氧饱和度与血清脑钠肽呈负相关(r=-0.469,P<0.01);脑氧饱和度和血清脑钠肽水平预测AIS患者机械取栓术后出血转化的最佳截断点分别为55%、239.91 ng/L,ROC曲线下面积(AUC)分别为0.800(95%CI:0.718~0.868)、0.832(95%CI:0.753~0.894),联合检测时AUC提升至0.882(95%CI:0.810~0.934)。结论 脑氧饱和度降低和血清脑钠肽水平升高与AIS患者机械取栓术后出血转化相关,二者联合具有更高的预测价值,可作为临床评估的参考指标。

Abstract:

Objective To explore the predictive value of cerebral oxygen saturation combined with brain natriuretic peptide for hemorrhagic transformation after mechanical thrombectomy in acute ischemic stroke (AIS). Methods The clinical data of 120 AIS patients treated with mechanical thrombectomy were retrospectively analyzed. All patients underwent head CT examination within 24 to 72 hours after the operation and were divided into the non-hemorrhagic transformation group (66 cases) and the hemorrhagic transformation group (54 cases) according to whether hemorrhagic transformation occurred. The differences in general information, laboratory test results, cerebral oxygen saturation and serum brain natriuretic peptide levels were compared between the two groups of patients. The receiver operating characteristic (ROC) curve was used to evaluate the value of cerebral oxygen saturation combined with serum brain natriuretic peptide in predicting hemorrhage transformation after mechanical thrombectomy in AIS patients. Pearson correlation analysis was used to analyze the relationship between cerebral oxygen saturation and serum brain natriuretic peptide. Multivariate Logistic regression was used to analyze the effects of cerebral oxygen saturation and serum brain natriuretic peptide on hemorrhage transformation after mechanical thrombectomy in patients with AIS. Results The atrial fibrillation, the time from onset to admission, the National Institutes of Health Stroke Scale (NIHSS) score at admission and the serum brain natriuretic peptide level were all higher in the hemorrhagic transformation group than those in the non-hemorrhagic transformation group (P<0.05), and the cerebral oxygen saturation was lower in the hemorrhagic transformation group than that in the non-hemorrhagic transformation group (P<0.05). The cerebral oxygen saturation was negatively correlated with serum brain natriuretic peptide in AIS patients (r=-0.469, P<0.01). The optimal cut-off points of cerebral oxygen saturation combined with serum brain natriuretic peptide level for predicting hemorrhage transformation after mechanical thrombectomy in AIS patients were 55% and 239.91 ng/L, respectively. The area under the receiver operating characteristic (ROC) curve (AUC) was 0.800 (95%CI: 0.718-0.868) and 0.832 (95%CI: 0.753-0.894), respectively. The AUC increased to 0.882 during the combined detection (95%CI: 0.810-0.934). Conclusion The decreased cerebral oxygen saturation and elevated serum brain natriuretic peptide levels are significantly associated with hemorrhage transformation after mechanical thrombectomy in AIS patients. The combination of the two has a higher predictive value and can be used as a reference index for clinical evaluation.
