Abstract
Introduction: To know frequency of abdominal aortic aneurysm (AAA) using ultrasound and clarify associated risk factors in 1000 Egyptians. Material and methods: Prospective study. 1000 patients aged 50 years or more (mean: 57.97 ± [7.68]) were examined by B-mode ultrasound at our radiology department to measure suprarenal maximum diameter of the abdominal aorta (wall to wall measurement) and to identify the occurrence of AAA (aneurysms were defined as 1.5 times the mean diameter). Demographic data and risk factors were also noted. Results: Mean aortic diameter in study population was 18.9 ± (3.2) mm. AAA diameter was 28.3 mm. Frequency of AAA was 1.5%. AAA prevalence: 2.35% in males versus 0.75% in females. Prevalence of AAA in different age groups: < 60 years (n = 653), 60–70 (n = 282), > 70 years (n = 65) was 6 (0.9%), 6 (2.1%), 3 (4.6%) respectively. Patients with AAA were older (P < 0.001), more often male (P < 0.001), smokers (P < 0.001). Conclusion: Study showed that mean aortic diameter was 18.9 mm and AAA is present in 1.5% of the study population which was less than that seen in previously conducted studies in other countries.
