Pulmonary segmentectomy is generally acknowledged to be more technically complex than lobectomy. Three-dimensional computed tomography (3D CT) angiography is useful for understanding the pulmonary arterial and venous branching, as well as planning the surgery to secure adequate surgical margins. Comprehension of the intersegmental and intrasegmental veins makes the parenchymal dissection easier. To visualize the segmental border, creation of an inflation-deflation line by using a method of inflating the affected segment has become the standard in small-sized lung cancer surgery. Various modifications to create the segmental demarcation line have been devised to accurately perform the segmentectomy procedure.
肺段切除术通常被认为比肺叶切除术更具技术复杂性。三维计算机断层扫描（3D CT）血管造影术有助于了解肺动静脉的分支，以及规划手术以确保足够的手术切缘。理解段间和段内静脉使实质解剖更容易。为了可视化段间边界，使用充气法创建充气-放气线已成为小肺癌手术的标准。已经设计了各种修改方法来创建段间分界线，以准确地进行肺段切除术。
