Abstract:
Purpose:
The aims were to assess different branching patterns of segmental bronchi in the right superior lobe (RSL), as well as to investigate the anatomical
diversity and sex-related variations of these branches in a large sample of the research population.
Methods:
10,000 participants (5428 males, and 4,572 females, mean age 50+/-13.5 years [SD] years; age range: 3-91 years) who underwent multi-slice CT
(MSCT) scans from September 2019 to December 2021 were retrospectively included. The data were applied to generate three-dimensional (3D)
and virtual bronchoscopy (VB) simulations of a bronchial tree using the syngo.via post-processing workstation. Following that, the reconstructed
images were interpreted to identify and categorize various bronchial patterns in the RSL. Cross-tabulation analysis and the Pearson chi-square test
(χ2) were used to calculate the component ratios of bronchial branch types and determine their relevance between male and female groups.
Results:
Our results revealed mainly six types for the RSL bronchial tree, i.e., (B1, B2, B3, 60.70%); (B1+2, B3, 18.72%); (B2+3, B1, 6.68%); (B1+3, B2,
7.57%); (B1, B2, B3, B*, 3.19%); (B1a+B3, B1b+B2, 3.14%). There were significant sex-related differences in the proportion of bronchial
branches in the RSL (P< 0.05).
Conclusion:
The current study has validated the presence of segmental bronchial variations in the RSL. These findings may have significant implications for
diagnosing symptomatic patients and performing particular procedures, including bronchoscopy, endotracheal intubation, and lung resection.
