Pdf Summary

This study aimed to analyze the anatomical variations of the left upper pulmonary blood vessels and bronchi based on three-dimensional reconstruction of chest CT. A total of 177 patients with early-stage non-small cell lung cancer (NSCLC) underwent video-assisted thoracic surgery (VATS) segmentectomy using preoperative three-dimensional CT reconstruction. The variations in blood vessels and bronchi were reviewed and analyzed. <br /><br />The study found that the branches of the left lingular pulmonary artery may mutate into the LS1, 2, 3 variant. The most common variation in the left upper lung is the bifurcation type of bronchus. The posterior apical segment artery of the left upper lobe does not strictly accompany its bronchus. <br /><br />The authors concluded that preoperative CT-based three-dimensional reconstruction of pulmonary arteries, veins, and bronchi is important in understanding the variations and accurately locating lesions before surgery. It can also help in effectively planning surgeries. The study found no new variations and the conclusions were consistent with earlier reports. Despite the complexity of variations, there are still some rules to follow in the left upper pulmonary vascular bronchus.<br /><br />Overall, this study provides insights into the anatomical variations of the left upper pulmonary blood vessels and bronchi based on three-dimensional CT reconstruction. The findings have implications for surgical planning and understanding the complexities of the pulmonary anatomy.
