Pdf Summary

This study aimed to analyze the anatomical variations of the left upper pulmonary blood vessels and bronchi based on preoperative three-dimensional reconstruction of chest computed tomography (CT) in patients undergoing video-assisted thoracic surgery (VATS) segmentectomy for non-small cell lung cancer (NSCLC). The study included a total of 177 patients and reviewed data such as clinical characteristics and variations in blood vessels and bronchi. <br /><br />The findings showed that the branches of the left lingular pulmonary artery could mutate into LS1, 2, 3 in 22% of cases. The most common variation in the left upper lobe bronchus was the bifurcation type (type A to G) in 92% of cases, with type A being the most prevalent. The posterior apical segment artery of the left upper lobe did not strictly correspond to its bronchus. <br /><br />The study concluded that the variations in the left upper lung blood vessels and bronchi are complex. Preoperative CT-based three-dimensional reconstruction is important in understanding these variations, accurately locating lesions before surgery, and planning surgeries effectively. Despite the larger sample size, the conclusions were consistent with previous reports, and no new variations were discovered. Although the variations are complex, there are still some rules to follow, and the current method of induction is reasonable and scientific. <br /><br />The study provided simplified schematic diagrams of the left upper lobe bronchus and specific reconstructions of the left whole lung bronchus.
