血管迷走性晕厥(Vasovagal syncope,VVS)是指各种刺激通过迷走神经介导反射,从而导致心动过缓及内脏和肌肉小血管扩张,结果造成血压降低、脑部缺血缺氧,表现为动脉低血压伴有短暂的意识丧失,无神经定位体征的一种综合征。迷走神经张力病理性增高是VVS的发病基础[1]。研究表明,晕厥可由心血管疾病、神经系统疾病及代谢性疾病等引起,而血管迷走性晕厥是其最常见的原因,据统计约占急诊晕厥患者的41%~66%,占儿童不明原因晕厥的80%,人群的20%~40%一生中曾发作过VVS[2,3]。此类晕厥在社区中发病率较高,但由于症状呈一过性,且有较强的不可预测性,需通过专业方法诊断,长期以来并未受到重视。VVS发病急,预后与个体及环境因素密切相关,若任由其发展而不加以治疗,后果可能非常严重[4]。 一、VVS的传统治疗策略
二、VVS的心脏神经靶向干预策略
三、VVS肾脏神经干预策略
