“…Kandathil et al suggest [ 19 ] that V6c belongs to the intersegmental veins, and complete dissection of V6 may damage these veins. Mimae et al [ 20 ] have proposed that injuring intersegmental veins may elevate the risk of postoperative hemoptysis complications. Although there was no significant difference in postoperative hemoptysis complications between the two groups, the VVPS group experienced early mild hemoptysis symptoms in three patients (resolved within one month postoperatively).…”

“…The relationship between lung volume and segmental anatomy has been deeply analyzed using 3D CT imaging [ 28 ]. It also allows for new analysis of the spatial relationship between structures, such as intersegmental planes and intersegmental veins [ 29 ]. Shibasaki et al demonstrated that 3D CT volumetry could predict postoperative pulmonary function independent of the resected lobe [ 30 ].…”

Radiologic reconstruction technology allows the wide use of three-dimensional (3D) computed tomography (CT) images in thoracic surgery. A minimally invasive surgery has become one of the standard therapies in thoracic surgery, and therefore, the need for preoperative and intraoperative simulations has increased. Three-dimensional CT images have been extensively used, and various types of software have been developed to reconstruct 3D-CT images for surgical simulation worldwide. Several software types have been commercialized and widely used by not only radiologists and technicians, but also thoracic surgeons. Three-dimensional CT images are helpful surgical guides; however, in almost all cases, they provide only static images, different from the intraoperative views. Lungs are soft and variable organs that can easily change shape by intraoperative inflation/deflation and surgical procedures. To address this issue, we have developed a novel software called the Resection Process Map (RPM), which creates variable virtual 3D images. Herein, we introduce the RPM and its development by tracking the history of 3D CT imaging in thoracic surgery. The RPM could help develop a real-time and accurate surgical navigation system for thoracic surgery.

“…Mimae et al . reported that the main root of the intersegmental vein (V 3 a+b) between the upper and lingular divisions was always located in the upper division, whereas the root of the intersegmental vein (V 6 b+c) between S 6 and basal segments was always located in the basal segment; it is important to know that intersegmental veins are not always located on the intersegmental plane when dividing the lung parenchyma along these intersegmental veins ( 20 ).…”

The anatomy of the lung was originally described based on data acquired from cadaveric studies and surgical findings. Over time, computed tomography (CT) and three-dimensional (3D) imaging techniques have been developed, allowing for reconstruction and understanding of lung anatomy in a more intuitive way. The wide adoption of 3D-CT imaging technology has led to a variety of anatomical studies performed not only by anatomists but also by surgeons and radiologists. Such studies have led to new or modified classification systems, shed light on lung anatomy from a useful surgical viewpoint, and enabled us to analyze lung anatomy with a focus on particular anatomical features. 3D images also allow for enhanced pre- and intra-operative simulation, improved surgical safety, enhanced educational utility, and the capacity to perform large-scale anatomical studies in shorter time frames. We will review here the key features of 3D-CT imaging of the lung, along with representative anatomical studies regarding (I) general lung anatomy, (II) anatomy of the right and left lobes, and (III) features of interlobar vessels. The current surge of 3D imaging analysis shows that the field is growing, with the technology continuing to improve. Future studies using these new and innovative methodologies will continue to refine our understanding of lung anatomy while enhancing our ability to perform safe and effective surgical resections.
