Previous studies have mainly described the frequencies of bronchovascular anatomical variations in pulmonary segments, but did not determine the differences between pulmonary segments and the regularity behind these anatomical variations. Here, we attempted to investigate the regularity of bronchovascular anatomical variations in different pulmonary segments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thin\u2010slice enhanced computed tomography data of 800 cases from our center were included in this study. Digitalized three\u2010dimensional virtual lung segmentation was done, the dominant and inferior lung segments of the right upper lobe were defined, and the regularity of anatomical variations was explored.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean volume ratio of the anterior segment of the right upper lobe (39.6\u2009\u00b1\u20098.6%) was highest, and that of the posterior segment (28.6\u2009\u00b1\u20097.9%) was lowest. Therefore, the dominant\u2010type segment (DS\u2009+\u2009SDS) was dominant in the anterior segment, accounting for 74.6% (597\/800), and the inferior\u2010type segment (SIS\u2009+\u2009IS) was dominant in the posterior segment of the right upper lobe, accounting for 71.5% of cases (573\/800). During the transformation of dominant and inferior lung segments, the corresponding regularity of anatomical variations could be displayed. For example, with an increase in the volume of the anterior segment of the right upper lobe, the occurrence rate of the bifurcated type of bronchus (B1\u2009+\u20092, B3), the \u201ccentral vein type\u201d and the involvement of the trunk inferior and ascending artery in the blood supply of anterior segment gradually
