目的探讨深度比法在肺段切除术中分割肺实质和肺结节深度分布的可行性。根据测量单位，将患者分为胸部组、大叶组和对称三扇区组。在每个单元中，将各自的支气管横断面的中心设为起点(O)。将O点与病变中心(A)相连，延伸至胸膜终点(B)，将放射线(OB)分成外、中、内三个区域。同时使用2维(2D)冠状、矢状面和轴位CT图像和3维(3D)重建图像验证深度比和相关区域分布。这项研究包括209名患者。年龄中位数为53岁，为男性。深度比区域划分组内一致性为100%。组间区域划分的一致性在三组之间不同(卡伯值0.511、0.517和0.923)。胸腔组、肺叶组和对称三段组纵隔紊乱发生率分别为69.4%、26.3%和4.8%(P<；0.001)。肺的3个对称扇区的深度比法最大限度地消除了纵隔结构的干扰，在三维空间中更准确地对肺实质进行了三层分割。以深度比为测量方法，对肺外2/3结节采用基于分段策略的亚叶切除是可行的。
To explore the feasibility of the depth ratio method partitioning the lung parenchyma and the depth distribution of lung nodules in pulmonary segmentectomy. Based on the measurement units, patients were allocated to the chest group, the lobar group, and the symmetrical 3 sectors group. In each unit, the center of the respective bronchial cross-section was set as the starting point (O). Connecting the O point with the center of the lesion (A) and extending to the endpoint (B) on the pleural, the radial line (OB) was trisected to divide the outer, middle, and inner regions. The depth ratio and relevant regional distribution were simultaneously verified using 2-dimensional (2D) coronal, sagittal, and axial computed tomography images and 3-dimensional (3D) reconstruction images. Two hundred and nine patients were included in this study. The median age was 53 (IQR, 44.5–62) years and 64 were males. The intra-group consistency of the depth ratio region partition was 100%. The consistency of the inter-group region partition differed among the three groups (Kappa values 0.511, 0.517, and 0.923). The chest group, lobar group, and symmetrical 3 sectors group had 69.4%, 26.3%, and 4.8% mediastinum disturbance, respectively (P<0.001). The depth ratio method in the symmetrical 3 sectors of the lung maximally eliminated the disturbance of the mediastinal structures and more accurately trisected the lung parenchymal in 3D space. Sublobar resection based on subsegments strategy is feasible for outer 2/3 pulmonary nodules when depth ratio is used as the measurement method.
