Abstract

Purpose: The objectives of this study were to evaluate various branching patterns of segmental bronchi in the left superior and lingular lobes and to survey the anatomical diversity and sex-related differences of these branches in a large sample of the study population.

Materials and methods: Overall, 10,000 participants (5428 males, and 4572 females, mean age 50 ± 13.5 years [SD] years; age range: 3-91 years) who underwent multi-slice CT (MSCT) scans between September 2019 and December 2021 were retrospectively included. Using the syngo.via post-processing workstation, the data were applied to generate three-dimensional (3D) and virtual bronchoscopy (VB) simulations of a bronchial tree. The reconstructed images were then interpreted to identify and categorize distinct bronchial patterns in the left superior and lingular lobes. Cross-tabulation analysis and the Pearson Chi-square (χ²) test were used to calculate the constituent ratios of bronchial branch types and determine their significance between male and female groups.

Results: Our results revealed mainly four distinct types for the left superior lobe (LSL) bronchial tree, i.e., (B1 + 2, B3, 76.13%); (B1 + 2 + 3, 17.32%); (B1 + 3, B2, 5.74%); (B1a + B3, B1b + B2, 0.81%) and two types for the left lingular lobe (LLL) bronchial tree, i.e., (B4, B5, 91.05%); (B4, B5, B*, 8.95%). There were no significant sex-related differences in the proportion of bronchial branches in LLL (P > 0.05). However, sex-related differences were significant in the proportion of bronchial branches in LSL (P < 0.05).

Conclusion: The current study has validated the presence of segmental bronchial variations in the left superior and lingular lobes. These findings may have a crucial effect on the diagnosis of symptomatic patients, as well as in carrying out procedures such as lung resections, endotracheal intubation, and bronchoscopies.

多层螺旋CT识别左上叶和舌叶节段性支气管的解剖类型。

目的：本研究的目的是评估左上叶和舌叶节段支气管的各种分支模式，并在大量研究人群中调查这些分支的解剖多样性和性别相关差异。材料和方法：总共有10000名参与者（5428名男性和4572名女性，平均年龄50岁） ± 13.5年[SD]年；年龄范围：3-91岁），他们在2019年9月至2021年12月期间接受了多层螺旋CT（MSCT）扫描。使用syngo.via后处理工作站，将数据应用于生成支气管树的三维（3D）和虚拟支气管镜检查（VB）模拟。然后对重建的图像进行解释，以识别和分类左上叶和舌叶的不同支气管模式。交叉表分析和Pearson卡方（χ2）检验用于计算支气管分支类型的构成比，并确定其在男性和女性组之间的显著性。结果：我们的结果主要揭示了左上叶（LSL）支气管树的四种不同类型，即（B1 + 2，B3，76.13%）；（B1 + 2. + 17.32%）；（B1 + 3，B2，5.74%）；（B1a + B3、B1b + B2，0.81%）和左舌叶（LLL）支气管树的两种类型，即（B4，B5，91.05%）；（B4，B5，B*，8.95%）。LLL中支气管分支的比例没有显著的性别差异（P > 而LSL中支气管分支的比例则存在显著的性别差异（P 结论：目前的研究已经证实了左上叶和舌叶存在节段性支气管变异。这些发现可能对有症状的患者的诊断以及肺切除、气管插管和支气管镜检查等程序产生至关重要的影响。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
