Summary
This study found 2.6% of men aged 65-74 had abdominal aortic aneurysms (AAA), with all cases linked to active smoking and other risk factors. The prevalence was lower than anticipated but higher than studies excluding smokers.
Area of Science:
- Vascular Surgery
- Preventive Cardiology
- Diagnostic Imaging
Background:
- Abdominal aortic aneurysm (AAA) screening in men aged 65-74 is crucial for early detection.
- Risk factor assessment, including smoking and hypertension, is vital for understanding AAA prevalence.
- Ultrasound is a primary non-invasive tool for AAA screening.
Purpose of the Study:
- To determine the prevalence of abdominal aortic aneurysms (AAA) in men aged 65-74 years using ultrasound.
- To describe the distribution of risk factors within the screened population and among those with AAA.
- To ascertain the hospital confirmation rate of diagnosed AAAs.
Main Methods:
- A cross-sectional study involving 115 men aged 65-74 years, recruited via telephone.
- Clinical interviews and abdominal ultrasound examinations were conducted.
- Data collection occurred between September 2014 and February 2015.
Main Results:
- An infra-renal AAA was detected in 2.6% of the sample (95% CI 0.54-7.4).
- Arterial hypertension was present in 51.3% and smoking/ex-smoking in 76.1% of participants.
- All three confirmed AAA cases involved active smokers with at least one additional risk factor.
Conclusions:
- The observed infra-renal AAA prevalence was lower than expected but exceeded rates in studies not accounting for smoking.
- Smoking appears to be a significant risk factor in this age group.
- Early screening and risk factor management are essential for AAA prevention.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
