摘　　要：目的探讨心房颤动(房颤)导管射频消融相关无症状脑梗死(SCI)发生的危险因素和临床特征。方法本研究纳入40例接受导管射频消融治疗的房颤患者,于术后24~72 h行头颅磁共振成像(MRI)检查,根据是否出现SCI分为SCI组和无SCI组,单因素分析比较患者病史资料、检查指标及术中情况。结果术后7例患者出现SCI,发生率为17.5%。统计分析发现左房后壁BOX消融与房颤导管射频消融术后SCI显著相关(P<0.001)。结论左房后壁BOX消融显著增加房颤射频消融术后SCI风险,临床上应谨慎评估左房后壁BOX消融的应用指征,减少SCI发生。Objective To investigate the risk factor and clinical characteristics of silent cerebral infarction(SCI)related to radiofrequency catheter ablation for atrial fibrillation.Methods A total of 40 atrial fibrillation patients receiving radiofrequency catheter ablation were enrolled.All the patients underwent cranial magnetic resonance imaging(MRI)examination 24 to 72 h after operation.According to the presence of SCI,they were divided into two groups:an SCI group and a non-SCI group.Both groups were compared for patient history,examination results and perioperative conditions through univariate analysis.Results Seven patients presented SCI after operation,with an incidence of 17.5%.BOX ablation in the posterior wall of the left atrium was significantly associated with SCI after radiofrequency catheter ablation in atrial fibrillation patients(P<0.001).Conclusions BOX ablation in the posterior wall of the left atrium significantly increases the risk of SCI after radiofrequency catheter ablation in atrial fibrillation patients.It is necessary to carefully assess the indication for BOX ablation in the posterior wall of the left atrium to reduce the incidence of SCI.
