Abstract

Background: Ultrasound is a straightforward and efficient technique for assessing aorta diameter and identifying infrarenal abdominal aortic aneurysm, a perilous condition associated with a high death rate. The three primary techniques for assessing abdominal aortic diameter using ultrasound are OTO, LTL, and ITI. The study aimed to (1) evaluate abdominal aortic diameter (AAD) utilizing three ultrasound techniques in individuals aged 60 and older within the community; (2) compare AAD measurements derived from the three methods as well as investigate the correlation between AAD and various risk factors. Methods and Materials: We randomly recruited study participants aged 60 years and older from various provinces and cities and measured abdominal aortic diameter via ultrasound in accordance with worldwide guidelines. Results: A total of 810 persons were enrolled, with men comprising 40.2%, and the mean age was 70.9 ± 7.56 years. All three methods OTO, LTL, and ITI demonstrated that the abdominal aortic diameter progressively diminished from the diaphragmatic hiatus to the aorto-iliac bifurcation. AAD in males was markedly greater than in females across all anatomical sites. OTO was the measurement technique that produced the highest AAD results in the infrarenal region; the average OTO value exceeded LTL by 1.3 mm and ITI by 2.6 mm (p < 0.001). Multivariate regression study revealed a substantial impact of age, male gender, and body surface area on abdominal aortic diameter. Conclusion: The AAD measurements acquired by the three ultrasound techniques in our investigation were notably consistent, with OTO producing the highest AAD findings. OTO, LTL, and ITI are all acknowledged in research evaluating abdominal aortic diameter using ultrasound.
