An abdominal aortic aneurysm (AAA) is an enlargement or bulging of the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta runs from the heart through the chest and abdomen. When it becomes weakened or stretched, it can form an aneurysm, which is a dangerous condition as the aneurysm may rupture, leading to life-threatening bleeding.
Did you know? AAAs are most commonly found in men over the age of 60, especially those with a history of smoking or heart disease.
Risk Factors and Causes
An AAA forms when the aorta wall weakens due to long-term high blood pressure, atherosclerosis, and smoking. Over time, inflammation in the aortic wall causes structural deterioration, leading to bulging.
Symptoms of Abdominal Aortic Aneurysm
Most AAAs are asymptomatic until they are large or ruptured. Common signs of a ruptured aneurysm include:
Important: If you experience any of these symptoms, seek emergency medical help immediately.
AAAs are often discovered incidentally during imaging for unrelated issues. Diagnostic methods include:
Management and Treatment
Abdominal aortic aneurysm is a silent yet deadly condition if not caught early. Regular screening, especially for high-risk individuals, and lifestyle changes can prevent rupture. Consult your healthcare provider for personalized recommendations.
