Objective: The aim is to look for the incidence of the incidental Abdominal Aortic Aneurysm (AAA) on routine abdominal Computed Tomography (CT scans) based on a single tertiary center at the Kingdom of Saudi Arabia (KSA).Methods: A retrospective study in which a review of all abdominal CT scans performed in one institution from 2011 to 2016 was conducted. Our target population was males aged between 65- 75 years old. The CT scans were reviewed by investigators trained in reviewing and measuring the aortic diameter. The maximal anterior-posterior diameter of the infra-renal abdominal aorta was measured on transverse cuts. The aortic diameter was recorded and the measurements were taken by two investigators independently for each CT scan. Any discrepancy of more than 15% was then reviewed by the primary investigator.Results: The total number of reviewed CT scans was 2032. The mean age was 70 ± 3 years, and the mean aortic size was 1.9 ± 0.3 cm. Only 6 cases (0.3%) found to have AAA (sizes ≥ 3 cm), with a mean age of 72 ± 3 years. There was a statically significant difference in age between those who had AAA and those who did not have AAA (72 ± 3 vs. 70 ± 3 years, with a P value of 0.0433).Conclusion: Our data suggests that the incidence of incidental AAA is low. A national pilot screening program in the non- hospital population would provide more robust evidence on the incidence of AAA in the KSA.
