ABSTRACT

Introduction: The skill scope in the airways endoscopic study should be based on the bronchial anatomy knowledge, its divisions, nomenclature and the normal endobronchial findings.
Objective: Methods: A descriptive, prospective cross-sectional study was carried out in 2000 patients, over a period of 12 years. A complete review of the right bronchial tree these variants was performed on these patients.
Results: The most frequent division was the bifurcation with 58.4%, in the upper lobar bronchus. The middle lobar bronchus always bifurcated. In segment B6, bifurcation predominated (87.7%), and the most frequent was type B6 and B6 b + c. The rest of the basals behaved as follows: the paracardiac segment did not appear in 8.15%, bifurcation predominated (89.15%) and out of these, B8 and B9 + B10 division. Regarding congenital malformations, we found 0.65% tracheal bronchus, 0.15% accessory cardiac bronchus and 5.15% subsurface bronchus.
Conclusions: The right bronchial tree in the Cuban population has its own characteristics.
