“…With 3D reconstruction, it is more convenient to identify each pulmonary lobe, especially for this atypical pulmonary segment. Recent literature has reported the prevalence of subsuperior segments ranging from 24% to 32.04%, which indicates that subsuperior segments were not very rare in clinical work (19,20). Usually, the subsuperior segment is difficult to identify by using the routine CT images due to its tiny bronchus (B*), artery (A*), and vein (V*).…”

BackgroundAn increasing number of lung ground-glass nodules (GGNs) have been detected ever since low-dose computer tomography started growing in popularity. Three-dimensional (3D) reconstruction technology plays a critical role in lung resection, especially in segmentectomy. In this study, we explore the role of 3D reconstruction in thoracoscopic complex segmentectomy of lower lung lobe.MethodsA total of 97 patients who underwent complex segmentectomy of lower lung lobe from January 2021 to March 2022 were retrospectively analyzed. We divided these patients into a 3D group (n = 42) and a routine group (n = 55) based on preoperative 3D reconstruction or without this procedure. The demographics of patients and GGNs were collected and perioperative outcomes were compared between the two groups.ResultsAll of the baseline characteristics between the groups were comparable (all P > 0.05). There was no 30-day postoperative mortality and conversion in the two groups. The operation time of the 3D group was significantly shorter than that of the routine group (111.4 ± 20.8 min vs. 127.1 ± 32.3 min, P = 0.007). The number of stapler reloads during surgery in the 3D group was less than that in the routine group (9.0 ± 2.2 vs. 10.4 ± 2.6, P = 0.009). The rate of air leakage on postoperative days 1–3 was lower in the 3D group (11.9% vs. 30.9%, P = 0.027). In addition, the resection margins of all patients in the 3D group were adequate, while four patients in the routine group had inadequate resection margins, although there was no statistically significant difference (P = 0.131). Intraoperative blood loss, postoperative drainage, postoperative hospital stay, pneumonia/atelectasis, and hemoptysis were similar between the two groups.ConclusionsFor performing complex segmentectomy of the lower lung lobe, the procedure of 3D reconstruction may shorten the operation time, decrease the number of stapler reloads, prevent postoperative air leakage, and guarantee a safe surgical margin. Therefore, 3D reconstruction is recommended for complex segmentectomy of the lower lung lobe.

“…S∗ is not rare. 1 , 2 , 3 Therefore, anatomic knowledge of S∗ bronchovascular patterns is important for thoracic surgeons, especially when performing single or combined S∗ segmentectomy safely. Maki and colleagues 2 reported that the intersegmental veins between S 6 and S∗ are V 6 b or V 6 c in the left lung.…”

“…The subsuperior segment (S∗), observed independent subsegment between S 6 and basal segments of the lower lobe, has a prevalence of 32.04% and frequencies of 20.4% and 24.0% in the right and left lungs, respectively. 1 , 2 , 3 , 4 Therefore, it is expected that many thoracic surgeons will recognize S∗ and perform single or combined S∗ segmentectomy in the future. However, few reports regarding surgical techniques and anatomic features focus on S∗, 4 , 5 with no studies on subsuperior segmental vein (V∗) anatomy in S∗ segmentectomy.…”

“…Also, several 3D-CT imaging studies have enrolled a large number of patients within a very short amount of time, some including more than 1,000 cases and others occasionally exceeding 5,000 cases ( 17 , 21 – 23 ). Such large-scale analyses would be difficult in a cadaveric study.…”

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.
