Morphological analysis of bronchial arteries and variants with computed tomography angiography, and its relevance in the treatment of massive hemoptysis

Massive hemoptysis is a life‐threatening clinical event. Its main etiology is secondary to rupture of the bronchial arteries and rarely from other systemic arteries or the pulmonary artery. The aim of our study was to determine the prevalence of anatomical variants of bronchial arteries using computed tomographic angiography in a population of northeastern Mexico.
