经支气管镜肺减容术(BLVR)是国际上治疗重度慢性阻塞性肺疾病(COPD)合并肺气肿患者的热点技术,它可经多种方法实现,如支气管内活瓣置入(EBV)、气道旁路支架、热蒸汽消融、生物肺减容、支气管内线圈置入、支气管内封堵等技术。目前国内外临床研究最多的是EBV,研究显示具备高异质性肺气肿,叶间裂完整和靶肺叶无旁路通气三要素的患者EBV疗效最好。新近出现的高分辨率CT(HRCT)及Chartis评估系统可以系统解决上述三要素问题,提高了EBV成功率及疗效,极具开发应用前景。文中综述了HRCT与Chartis评估系
Transbronchial lung volume reduction (BLVR) is an international hotspot technique for the treatment of patients with severe chronic obstructive pulmonary disease (COPD) complicated with emphysema. It can be achieved by a variety of methods, such as endobronchial valve implantation (EBV) , Airway bypass stents, thermal steam ablation, biological lung volume reduction, bronchial coil placement, and bronchial occlusion techniques. At present, the most clinical research at home and abroad is EBV. The study showed that patients with EBV with the highest heterogeneity of emphysema, complete interlobar rupture, and no bypass ventilation of target lung lobes were the best. The recent emergence of high resolution CT (HRCT) and Chartis assessment system can systematically solve the above three issues, improve the success rate and efficacy of EBV, great development and application prospects. The article reviews HRCT and Chartis assessment
