Abdominal Aortic Aneurysm may lead to danger depending on the size and growing of the aneurysm.
The chief danger of AAA is rupture, which is usually fatal.
Once a part of the aortic wall weakens, the force of blood pumped from the heart can stretch the wall into an aneurysm. If it ruptures, blood pumping from the heart causes hemorrhaging (fast and heavy bleeding) into the abdomen. Only about half of the people who suffer a ruptured aneurysm live long enough to get to the hospital.
The larger the aneurysm or the faster it grows, the greater the risk of rupture. Preventing rupture of an aneurysm is one of the goals of treatment.
Dissection is also a danger. Sometimes, a tear can occur on the inside layer of the aorta, resulting in blood seeping in among the layers of the artery wall and creating a dissecting aortic aneurysm or aortic dissection.
Since a large portion of patients don’t show any symptom, people may not know about the existence of aortic aneurysm in their body until the moment of rupture. This raises the risk. Screening is an important step to reduce the risk of abdominal aortic aneurysm.
