Context: Lung cancer causes the highest mortality from all malignant neoplasms, both worldwide and in Cuba. Therefore, the knowledge of complex anatomical variations and accurate understanding of individual anatomy has become increasingly significant for thoracic surgeons when performing precise and safe surgery. Objective: To Describe the main anatomical variants in bronchial and segmental arteries, in human lungs. Methodology: A descriptive and cross-sectional study was carried out in 50 human lungs blocks, obtained by necropsy, from the Legal Medicine Department, of the Amalia Simoni Clinical and Surgical Teaching Hospital in Camagüey. Results: Observing the variants in the segmental bronchi according to number, the supernumerary bronchi B1, B2 and B3 prevailed in both lungs. Most parts presented supernumerary segmental arteries in both lungs A1, A2, A3 and A6. Variations in the origin, both in bronchi and arteries, were unusual. Conclusions: The number variants prevailed over those of origin, they were most frequently observed in the upper lobes of both lungs and duplication predominated.Downloads
