摘　　要：随着低剂量计算机断层扫描在肺癌筛查方面的应用,肺结节检出率逐年增高。肺结节是有潜在恶性或从良性到恶性生长过程的可能,使患者面临巨大心理压力。若积极手术干预,可能会切除肺组织,损失肺功能,甚至造成医疗资源的浪费;而消极处理可能导致肿瘤进展,失去早期治疗的机会。对于肺结节的诊治,需要发现后既能快速诊断,又能立即治疗的方法。电磁导航支气管镜下微波消融能解决这一问题。电磁导航支气管镜以电磁定位技术为基础,结合薄层计算机断层扫描虚拟图像路径对肺结节精准定位,通过支气管镜经自然通道以微侵入的方式达到病变部位,获取组织细胞学诊断。微波消融术是肿瘤热疗领域中的新兴技术,在电磁导航支气管镜引导下,将微波天线从自然通道送达肿瘤内,肿瘤组织在短时间内达到70~160℃,诱导肿瘤细胞发生凝固性坏死。该文介绍了电磁导航支气管镜下微波消融在治疗肺结节中的应用进展。With the application of low-dose computerized tomographic scanning(CT)in the screening of lung cancer,the detection rate of lung nodules has increased year by year.Lung nodules may be an underlying malignancy or have an potential of a benign to malignant growth process.Patients are facing huge psychological pressure.If active surgical intervention may remove lung tissue,lose lung function,and even cause waste of medical resources;negative treatment may lead to tumor progress and lose the chance of early treatment.For the diagnosis and treatment of lung nodules,we need a method that can be able to diagnose quickly and immediately treat it after discovery.Microwave ablation under the electromagnetic navigation bronchial mirror can solve this problem.The electromagnetic navigation bronchial mirror is based on electromagnetic positioning technology,combined with thin layer CT scaning the virtual image path to accurately position the lung nodules,and achieve the lesion site in a minimally invasive way through the natural channel of the bronchial mirror to obtain the diagnosis of tissue cytology.Microwave elimination is an emerging technology in the field of tumor hyperthermia.Under the guidance of electromagnetic navigation bronchoscopy,the microwave antenna is delivered to the tumor from the natural channel.The tumor tissue reaches 70~160℃in a short period of time,which induces coagulative necrosis in tumor cells.This article introduces the application progress of electromagnetic navigation bronchial mirror microwave ablation in the treatment of lung nodules.
