To preserve blood supply to the trachea and bronchus in the surgical procedure for esophageal cancer, anatomical characteristics of small bronchial arteries which course in front of the trachea were analysed by three-dimensional computed tomography (3D-CT) and digital subtraction angiography (DSA).
In the 3D-CT study using five mediastina, three dimensional images of the bronchial arteries were reconstructed after the injection of contrast medium into the intercostobronchial arteries. Thus the detailed vascular network of the course of the small bronchial arteries in front of the trachea could be delineated.
In the DSA study using seven mediastina, through this network of bronchial arteries, the branches originating from the aorta and the arteries supplying the cranial portion of the trachea could be viewed. These results indicate that the bronchial arteries are connected by a vascular network in front of the trachea.
Based on these detailed findings, it is considered critical to avoid damage to the intercostobronchial artery and also the network of bronchial arteries in order to preserve blood supply to the trachea and bronchus.
