“…Surgeons should pay attention to this varation to avoid injury of MA when they plan to perform an apical segmentectomy or anterior segmentectomy. In addition, some studies have reported [11] that some branches of MA can arise from the basal segment of RPA, while we did not nd this variation in our study. The most common type of A6 is one branch (65.9%), followed by two branches (33.5%).…”

“…For patients with this variation, serious attention should be taken during resection of superior segment of the lower lobe to avoid vessel branches injury and bleeding. Three-branches of A6 was reported by Amore [11] and has a low rate (less than 1%), which may be the reason why this variant type was not found in our study. In our study we nd 41 patients (22.9%) had no Asc.A2 and all of branches of A2 originated from the rst branch of RPA.…”

“…It can also shorten the learning curve of surgery to 30 cases. Although previous studies [10][11][12][13][14][15] summarized the common anatomical types of segmental bronchi and blood vessels through 3D reconstruction to facilitate the surgeon's learning of anatomical knowledge and better preoperative planning, interlobar artery of right lobe was lacked. Therefore, in this study, the common types and rare variants of interlobar artery in right lobe were classi ed and summarized through thin-slice CT scan combined with 3D reconstruction.…”

Purpose To analysize and summarize branching patterns types of the interlobar portion of right pulmonary arteries (RPA) through chest thin-slice CT scan and three-dimensional reconstruction.Methods A total of 179 patients (58 males and 121 females, with an average age of 53.9 years) were retrospectively included from December 2020 to December 2021 in the Thoracic Surgery Department of Ningbo First Hospital. All patients completed preoperative thin-slice CT scan and three-dimensional reconstruction of the chest. The clinical data and branching patterns were collected. Data were analyzed using SPSS 21.0. Results The branching patterns types of the interlobar portion of RPA were divided into 4 types according to the order and number of branches: Type I (145/179, 81.0%), Asc.A2, MA, A6; Type II (28/179, 15.6%) , Asc.A2 deletion, MA, A6; Type III (5/179, 2.8%), Asc.A2, A6, MA; Type IV (1/179, 0.6%), MA, Asc.A2, A6; I type is the most common. Further, according to the number of branches of MA and A6, it can be subdivided into 15 sub-categories.Conclusion Chest thin-slice CT scan and 3D reconstruction can provide surgeons accurate lung anatomy, which helps surgeons make preoperative planning, and complete surgery successfully.

“…In addition, inexperienced surgeons require a learning curve of 30 cases for 3D reconstruction-assisted VATS anatomical sublobar resections. Although previous studies [10][11][12][13][14][15] summarized the common anatomical types of segmental bronchi and blood vessels through 3D reconstruction to allow surgeons to learn the relevant anatomy and improve preoperative planning, descriptions of the branching patterns of the interlobar portion of right pulmonary arteries were lacking. Therefore, in this study, the common types and rare variants of the interlobar artery in the right lobe were classified and summarized using thin-slice CT scans combined with 3D reconstruction.…”
