Abstract:
Objective To explore the effect of variation of the anatomical structure on the surgical method of segmentectomy, after the three-dimensional(3D) reconstruction of the pulmonary vessels,which provide the basis of imaging anatomy for clinical segmentectomy. Methods A total of 100 adult lung samples with no obvious abnormalities in enhanced CT were randomly selected from Xiangya Hospital of Central South University from 2019 to 2020, respectively, and three-dimensional reconstruction was performed for all-round observation of the main and branch routes of pulmonary vessels. Results The variation rate of left main pulmonary artery was 1%, the variation rate of posterior apex and anterior segment artery was 18%, the variation rate of lingual segment artery was 10%, the variation rate of dorsal segment artery was no variation, and the variation rate of basilar segment artery was 1%. The variation rate of right main pulmonary artery was 1%, the variation rate of posterior apex and anterior segment artery was 17%, the variation rate of lingual segment artery was 22%, the variation rate of dorsal segment artery was no variation, and the variation rate of basilar segment artery was 13%. The variation rate of main left pulmonary vein was 3%,the variation rate of the posterior apical and anterior segment vein was 20%, the variation rate of the lingual segment vein was 16%,the variation rate of the dorsal segment vein was 1%, and the variation rate of the basal segment vein was 19%. There was not variation in the main vein of the right lung, and the variation rate of posterior apical and anterior segments vein was 25%, the variation rate of medial and lateral segments vein was 16%, the variation rate of dorsal segment vein was 1%, and the variation rate of basal segment vein was 28%. Conclusion The anatomical structure of the pulmonary system is complex and diverse, especially the combination of the apical-posterior segment, the anterior segment and the basal segment, the posterior segment has commonly a fixed anatomical course,the medial segment and the lateral segment are different with traditional anatomical position relation. The 3D reconstruction technique can accurately and clearly reflect the course of pulmonary vessels and summarize their variation types, providing imaging data for clinical imaging location diagnosis and evaluation of vascular anatomy before pulmonary segmentectomy.
