Abstract
Thoracic duct injury leads to “chylothorax”. We found a close relationship of topographical anatomy between right bronchial artery and thoracic duct from esophageal cancer operations. We retrospectively analyzed topographical anatomy of right bronchial artery and location of thoracic duct in 124 cases operated in 2012. Of 124 cases, we recognized 8 cases of anomalous right bronchial artery. In these cases, the right bronchial artery originated directly from descending aorta without connections with third intercostal artery. When the right bronchial artery has a connection with third intercostal artery, the thoracic duct was located within the loop of the right bronchial artery. However, in these 8 anomalous cases, thoracic duct was located dorsally outside the loop of the right bronchial artery without exceptions. We have to be very careful in exploring the thoracic duct when we notice the anomalous right bronchial artery during esophageal cancer operation.
