Abdominal aortic aneurysm (AAA) refers to the abnormal dilation or weakening of the abdominal segment of the aorta—the largest artery in the human body. While smaller aneurysms often remain asymptomatic and undetected, larger or rapidly expanding AAAs can result in significant abdominal or back pain and pose a substantial risk of rupture, which is frequently fatal.

Certain populations are at elevated risk, notably individuals over 60 years of age, smokers, those with hypertension, patients with atherosclerosis, and persons with a family history of aneurysms. Early identification through imaging modalities such as ultrasound or computed tomography (CT) is essential; timely diagnosis allows for proactive management and reduces the likelihood of catastrophic outcomes.

Management strategies for AAA are primarily contingent on aneurysm size and growth dynamics. Small, stable aneurysms are typically monitored at regular intervals with imaging, alongside lifestyle modifications aimed at controlling blood pressure and encouraging smoking cessation. Conversely, large or rapidly expanding aneurysms may necessitate surgical intervention. Options include traditional open surgical repair or endovascular aneurysm repair (EVAR), the latter being a minimally invasive approach. With vigilant monitoring and appropriate intervention, the risk of rupture can be significantly diminished, supporting improved long-term vascular health and patient survival.
