Abstract:
Objective:The extensive development of anatomical pulnonary segmentectomy requires thoracic surgeons to be familiar with the anatomical variations of the lung segment. The purpose of this study is to analyze the anatomical patterns of the right upper lobe lung segment using three-dimensional reconstruction, and to count rare variant types.Methods:From October 2017 to March 2020, 101 patients with small pulmonary nodules who were undergo segmental resection in our center were subjected to preoperative three-dimensional reconstruction of the lung structure, and the reconstruction data was retained for the statistics and analysis of the anatomical structure in the right upper lung lobe.Results:The right upper lobe bronchus is the most common with three branches(77/101), followed by two branches(16/101) and four branches(7/101). The two branches(70/101) of the right upper lobe pulmonary artery are the most common, followed by single branch(19/101) and three branches(11/101). In rare cases, four branches(1/101 cases) can be seen. The two branches(63/101) of the right upper pulmonary vein were the most common, followed by three branches(32/101) and single branch(6/101). In addition, a total of 12 rare mutations were counted. There were 2 variants in the bronchus, totaling 2 cases; 4 rare variants in the pulmonary artery, 13 cases total; 6 rare variants in the pulmonary vein, 10 cases total.Conclusion:The lung anatomy is complex and has many variations. The surgeon should fully grasp the anatomical structure of the lung segment of the patient's operating area before surgery, the data in this article will be a valuable reference for thoracic surgeons to carry out the upper right lobe segmentectomy.
