Abstract

Objective: This study aimed to compare the morphological characteristics of the abdominal aorta between males and females using 128-slice computed tomography (CT) imaging. The parameters assessed included the origin and termination levels, diameters at three main segments, total length of the abdominal aorta, and the angle formed by the two common iliac arteries. Methods: A retrospective, cross-sectional descriptive study was conducted on 193 patients aged 18 years or older who underwent contrast-enhanced abdominal CT scans at the Imaging Center of Tam Anh General Hospital, Hanoi, between December 2023 and December 2024. Morphological measurements of the abdominal aorta were analyzed by sex using MIP and VR reconstruction software, and statistical analysis was performed using SPSS 20.0. Results: The abdominal aortic diameters in males were larger than in females at all measured locations: origin (21.17 ± 2.6 mm vs. 18.5 ± 2.2 mm), above the renal artery origin (18.64 ± 2.2 mm vs. 16.23 ± 2.05 mm), and at the terminal segment (15.54 ± 2.01 mm vs. 13.56 ± 1.69 mm). The average abdominal aortic length was 143.88 ± 11.57 mm in males and 134.03 ± 10.66 mm in females. The mean angle formed by the two common iliac arteries showed no significant difference between sexes (males: 42.69°, females: 43.73°). Conclusion: The abdominal aorta in males is significantly larger in both diameter and length compared to females. However, there is no notable difference between sexes in the angle formed by the common iliac arteries. These findings provide valuable imaging data to support accurate evaluation, diagnosis, and vascular intervention tailored to patient sex.
