Morphological Analysis of Bronchial Arteries and Variants with Computed Tomography Angiography

Figure 1

Branching patterns of bronchial arteries. Left lower letter indicates the corresponding pattern described in our study and the right lower number corresponds to the classification by Cauldwell et al. (a line means that the pattern was not included in the Cauldwell classification). Center lower number represents the total frequency with male and female reported between parenthesis (M = male; F = female). (a) shows the pattern I of our study, type 1 of Cauldwell, corresponding to “typical” anatomy of bronchial arteries described in medical textbooks. (b–f) show the most frequent branching patterns found in our study (patterns A to E, resp.).
