[Bronchial arteries: anatomical and clinical studies and strategies in surgical approach]

One of the most important and controversial aspects of thoracic surgery is due to the topographical and surgical anatomy of the vascular structures involving the mediastinum. The knowledge of the so-called "vascular time", in fact, allows to face more complicated surgical situations, typical of the most specialistic thoracic surgery. The bronchial arteries represent a paradigm of what we have just stated. The study of their anatomy (number, position, origin, distribution and relationships with the mediastinal structures) is of relevant importance, not only for the interest the bronchial vascular tree arises in tracheo-bronchial surgery and in pulmonary transplantology, but also for the knowledge of the pathogenesis of some processes regarding pulmonary and pleural pathologies. The aim of this paper is to evaluate the real clinical interest of bronchial arteries, with an analytic study of the anatomy of vessels, and with the possibility to show the most frequent and characteristic anomalies involving the origin and course of these arteries.
