Branching patterns and variations of the bronchus and blood vessels in the superior segment of the right lower lobe: a three-dimensional computed tomographic bronchography and angiography study.

ABSTRACT:

Background

Superior segmentectomy is classified as simple due to the single intersegmental plane between the superior and basal segments. However, oncological outcomes in patients undergoing superior segmentectomy tend to be worse compared to those receiving other segmentectomy. The aim of this study is to determine the branching patterns and variations of the bronchus and blood vessels of the superior segment of the right lower lobe (RS⁶).

Methods

Three-dimensional computed tomographic bronchography and angiography (3D-CTBA) was reconstructed in 316 patients who underwent enhanced chest computed tomography (CT) and subsequent surgery in our center from November 2018 to March 2021.

Results

The bronchus in RS⁶ consisted of a single stem in 96.5% c
