【摘要】 目的 探讨急性前循环大血管闭塞性（LVO）脑梗死机械取栓（MT）术后出血转化（HT）发生率及影响因素。方法 回顾性收集 107 例 2020-01—2021-12 序贯就诊于常德市第一人民医院神经内科确诊为急性前循环 LVO 脑梗死，并行急诊 MT 术患者临床资料，采用单因素和多因素 Logistic 回归分析 MT 术后 HT 发生影响因素，并行曲线拟合及阈值效益分析。结果 107 例急性前循环 LVO 脑梗死患者中 32 例术后发生 HT，占 29.91%，包括症状性 HT 13 例（12.15%）和非症状性 HT 19 例（17.76%）。多因素 Logistic 回归分析显示，术前侧支循环代偿程度低、术前急查外周中性粒细胞计数水平高、中性粒细胞/淋巴细胞比值（NLR）升高是急性前循环 LVO 脑梗死 MT 术后 HT 发生的独立危险因素（P<0.05）。应用平滑曲线拟合显示，术前急查 NLR 水平与急性前循环 LVO 脑梗死 MT 术后 HT 发生风险呈 J 型曲线关系，行阈值效应分析发现，曲线存在饱和效应值为 6.3。结论 术前侧支循环代偿程度低、术前急查外周中性粒细胞计数水平高、NLR 升高是急性前循环 LVO 脑梗死 MT 术后 HT 发生的独立危险因素。监测术前 NLR 变化可成为预测急性前循环 LVO 脑梗死 MT 术后 HT 发生风险的有效措施。

【Abstract】 Objective anterior circulation LVO cerebral infarction after MT. To investigate the incidence and influencing factors of HT patients with acute Methods The clinical records of 107 patients with acute anterior circulation LVO cerebral infarction and underwent MT admitted to the first people’s hospital of Changde city from January 2020 to December 2021 were reviewed retrospectively. Univariate and multivariate logistic regression were used to analyze the risk factors，curve fitting and threshold benefit analysis were performed to further assess the association between the risk factors and HT. Results Among 107 patients with ACI，32 cases （29.91%）developed HT after MT，including 13 cases of symptomatic HT （12.15%）and 19 cases of non-symptomatic HT （17.76%）. Multivariate logistic regression analysis illustrated that lower preoperative compensatory degree of collateral circulation，higher peripheral neutrophil count and higher preoperative NLR level were independent risk factors for HT after MT. Smooth curve fitting showed that the relationship between preoperative NLR level and HT occurrence after MT presented a J-shaped curve. Further threshold benefit analysis showed that when NLR <6.3，The risk of HT after MT was positively correlated with NLR level. Conclusion lower preoperative compensatory degree of collateral circulation，higher peripheral neutrophil count and higher preoperative NLR level were independent risk factors for HT after MT. Monitoring preoperative NLR changes can be an effective measure to predict the risk of HT after MT in acute anterior circulation LVO cerebral infarction.
