Bronquio cardíaco accesorio y otras variantes de la anatomía tráqueo-bronquial

Abstract

Among the variations of bronchial anatomy, we can find dysplastic bronchial branches, an absence of bronchial branches, or supernumerary branches. Although many of them are asymptomatic, it is essential to know them because they may be associated with hemoptysis, recurrent infections, empyema, or complications secondary to various procedures (e.g. endotracheal intubation, brochoscopy, bronchoalveolar lavage, biopsy, endobronchial treatments, stent installation, brachytherapy and lung surgeries among others). In this study we used computed tomography to describe some of the most prevalent bronchial variations, including accessory cardiac bronchus, tracheal bronchus, and bridge bronchus among others.
