An aneurysm is an abnormal bulge in the wall of an artery. Normally, the walls of arteries are thick and muscular, allowing them to withstand a large amount of pressure. Occasionally, however, a weak area develops in the wall of an artery. This allows the pressure within the artery to push outwards, creating a bulge or ballooned area called an "aneurysm."
Aneurysms can form in any blood vessel, but they occur most commonly in the aorta (aortic aneurysm). The aorta is the largest artery in the body. It carries blood from the heart to the rest of the body. Aortic aneurysms can occur in two main places:
For someone with heart disease, diet is a big deal. Along with other healthy habits, it can slow or even partially reverse the narrowing of the heart's arteries and help prevent further complications.
You can help a loved one who has heart disease by adopting a diet that curbs LDL (''bad'') cholesterol, lowers blood pressure, lowers blood sugar, and helps with weight loss.
The best strategy: Focus on what the person with heart disease can eat, not just what's off-limits. Research shows that adding...
Congenital abnormality. A number of conditions, such as Marfan syndrome or bicuspid aortic valves are present at birth and can cause weakness of the artery walls.
Syphilis used to be a common cause of thoracic aneurysms, but it is no longer as common.
Note: Instead of causing a bulge in a thinned artery wall, aortic aneurysms occasionally occur between layers of the artery itself. This is called a "dissecting aneurysm." Blood starts to flow in the separated artery layers cutting off blood flow in the artery. This condition can rapidly lead to rupture of the artery.
What Are the Symptoms of an Aortic Aneurysm?
Aortic aneurysms often cause no symptoms at all. But if present, symptoms include:
Tearing pain in the chest, abdomen, and/or middle of the back between the shoulder blades.
Thoracic aneurysms may cause shortness of breath, hoarseness, cough (due to pressure on the lungs and airways), and difficulty swallowing (pressure on the esophagus)
Rupture of an aneurysm can cause loss of consciousness, stroke, shock, or a heart attack
If you are experiencing sudden unexplained chest, abdominal, or back pain, or any of the other symptoms mentioned above, seek medical attention.
