Abstract

Purposes: To describe the characteristics of the left renal vein (LRV) in relation to body mass index (BMI) and the aortic-mesenteric angle (AMA) in adults as seen on computed tomography. Material and methods: This descriptive study was conducted on 627 individuals who underwent CTscans at Tam Anh General Hospital, Ho Chi Minh City, from July 2023 to December 2023. The study included parameters such as LRV characteristics (maximum diameter, minimum diameter, the compression ratio, LRV angle, and beak sign) and the aortic-mesenteric angle. Results: The prevalence of the beak sign is 8,8%. The average maximum diameter of the LRV is 10,23 ± 1,7 mm, and the minimum diameter is 4,72 ± 1,96 mm; the compression ratio is 2,52 ± 1,1; the LRV angle is 17,94 ± 11,19 degrees, and the AMA is 60,79 ± 24,97 degrees. Significant differences exist between males and females. The average value of the AMA increased progressively from the underweight group to the normal weight group and then to the overweight group, at 42,56 degrees, 56,37 degrees, and 74,74 degrees, respectively (p<0.001), with a moderate positive correlation (p<0.001). Conversely, the average value of the LRV angle decreased from the underweight group to the normal weight group and then to the overweight group, at 26,7 degrees, 18,71 degrees, and 14,36 degrees, respectively (p<0.001), with a weak negative correlation (p<0.001). Conclusion: There is a correlation between BMI and both the aortic-mesenteric angle and the LRV angle
