三维CT支气管血管成像技术在精准肺段切除中应用的研究进展

Application progress of 3D-CTBA technique in precise segmentatomy

随着低剂量螺旋CT(LDCT)扫描检查的普及,以孤立性肺结节、磨玻璃结节为主要影像表现的早期肺癌的诊出率明显增加。对于这些患者而言,目前研究表明肺段切除具有与肺叶切除相似的肿瘤学效果,而且可保留更多的肺功能、提高生活质量,因此解剖性肺段切除是肺叶切除的一种替代的手术方式。近年来基于医学影像学的三维重建技术发展迅速,其具有可在术前多层次、多角度了解解剖结构、结节位置、空间关系、设计手术路径等优势,在解剖结构复杂且具有个体化差异的胸腔镜解剖性肺段切除术中扮演着重要角色。笔者就目前三维重建技术在肺段切除中的应用作一综述,简单介绍该技术在精准肺段切除中的应用。

With the popularization of low-dose computed tomography( LDCT) scanning,the rate of the diagnosis of primary lung cancer for early-stage non-small cell lung carcinoma( NSCLC) is increasing,mainly because of a growing rate of solitary pulmonary nodule and ground-glass nodule. For these patients,recent studies have shown that segmentectomy and lobectomy have similar oncologic effects,while they can retain more lung function and improve the quality of life,so anatomical segmental resection is an alternative operation. In recent years,the three-dimensional reconstruction technology based on medical imaging has developed rapidly,which can be used to understand the anatomical structure,nodule position,spatial relationship,design of surgical path and other advantages in preoperative,and plays an important role in the thoracoscopic anatomical segmental resection with complex anatomical structure and individual differences. This paper reviews the application of three-dimensional reconstruction technology in segmental lung resection,and briefly introduces the application of this technology in precise segmental lung resection.
