Introduction: abdominal aortic aneurysms (AAA) are a vascular condition associated with high morbidity and mortality, particularly in cases of rupture. Their prevalence increases with age and is higher in individuals over 65 years, although they may occur from the age of 50 in the presence of cardiovascular risk factors such as smoking, arterial hypertension, and atherosclerotic disease. Most patients remain asymptomatic for long periods, and diagnosis is often incidental or occurs after complications arise. Early detection through ultrasound allows identification of aneurysms at early stages and facilitates clinical follow-up. Materials and Methods: during cardiovascular or abdominal ultrasound examinations, the anteroposterior and transverse diameters of the abdominal aorta were measured. Patients older than 50 years with risk factors for AAA were included. Public and private medical centers from different provinces of Argentina participated in this multicenter registry. Results: a total of 2148 patients were included, 1063 men and 1085 women. Seventy-seven AAAs were detected, corresponding to an overall prevalence of 3.58%. Most cases were observed in patients older than 65 years. Conclusions: ultrasound evaluation of the abdominal aorta during cardiovascular or vascular studies allows the detection of AAA in patients with risk factors.
