What is the most common type of aortic aneurysm?

The most common type of aortic aneurysm is the abdominal aortic aneurysm (AAA). This prevalence can be attributed to several factors, including the anatomical structure and blood flow dynamics within the abdominal aorta, where a weakness in the vessel wall is more likely to occur.

AAAs typically develop in specific patient demographics, particularly in older adults and those with risk factors such as smoking, hypertension, and a family history of vascular disease. The abdominal aorta is subject to various stressors and the nature of the abdominal cavity's movement can contribute to the formation of an aneurysm in this region.

In addition to being the most common, AAAs also pose significant health risks, including the potential for rupture, which can lead to life-threatening internal bleeding. Their prevalence in the population emphasizes the importance of screening and monitoring for those at risk. Understanding the characteristics of an AAA is crucial for cardiac sonographers, as it impacts imaging techniques and patient management strategies.
