Abstract
The study aimed to establish the normal diameters of the abdominal aorta at the different three levels using ultrasound among young Saudi females, to assess the correlation between the diameters and correlate the diameters with body mass index (BMI), waist, and wrist circumferences. This will facilitate the assessment of patients with suspected abdominal aortic aneurysm (AAA). This descriptive and prospective study was conducted from December 2018 to April 2019 at Princess Nourah Bint Abdulrahman University (PNU). One hundred participants of females between 18 and 25 years old were scanned. BMI, wrist, and waist circumferences were measured. Three aortic diameters were measured at three levels upper, middle, and lower. Mean +/- Standard deviation (Std.) and personal correlation in the Statically package for the social sciences (SPSS) program were used for data analysis. The mean aortic diameters +/- Std. are 1.3 +/- 0.2 cm, 1.1 +/- 0.2 cm, and 0.9 +/- 0.2 cm at the upper, middle, and lower levels, respectively. The differences between middle and lower, middle and upper, upper, and lower aortic diameters are significant (P- value < 0.05). There are no correlations between the diameters at different levels and BMI, and body circumferences (waist and wrist) (P-value. 0.05).The normal aortic diameters among young Saudi females were established. The aortic diameters can be calculated using different equations. Other studies with larger sample sizes are recommended because no significant correlations were found between the measurements and BMI, waist, and wrist circumferences.
