Research progress of three-dimensional computed tomography bronchography and angiography in anatomical segmental pneumonectomy

With the development and popularization of thin-layer CT technology, lots of smaller pulmonary nodules have been detected. In order to preserve more lung function under the obvious situation of aging problem of Chinese population, anatomical segmental resection has become a research hot-spot in field of general thoracic surgery. Because of the great variation of pulmonary vascular anatomy, the requirement of surgeons is very high, so three-dimensional reconstruction and operation planning become very important. At present, three-dimensional CT bronchovascular imaging is used in clinical practice to assist the implementation of anatomic segmental resection, so as to ensure the purpose of cutting edge and accurate resection. However, each reconstruction method has its own advantages and disadvantages, and the development of artificial intelligence will bring new changes. In this study, the application of three-dimensional computed tomography bronchography and angiography in anatomical segmental resection of the lung is reviewed.
