Aorta is our body’s largest and most important artery that carries blood from the heart to other parts of the body. The section of aorta that moves towards the abdomen is called the abdominal aorta and the aorta moving towards the chest is called the thoracic aorta. When blood is being pumped through aorta, the wall of the aorta can sometimes get bulged or swollen or torn causing the thoracic aortic aneurysm. Thoracic aortic aneurysm occurs very rarely and infects around six to eight persons in every ten thousand people. About a 15% of those cases report links to family history.
Common symptoms of thoracic aortic aneurysm:
Thoracic aortic aneurysm occurs in the body’s largest artery, the aorta, which passes from the heart through the chest. A few people experience no symptoms until the aorta wall breaks or expands. While for others, symptoms will be detected while they are diagnosed for some other illness or disorders.
Symptoms of aortic aneurysm begins when
> Blood leaks from the walls of the aorta
> The aneurysm is torn or if the aorta wall ruptures
Symptoms when the thoracic aortic aneurysm has developed:
> Chest pain
> Increased heart rate
> Swelling on head or neck
> Swallowing problems
> Swelling of the arms
> Breathing difficulty
Common causes of thoracic aortic aneurysm:
There is no proper reason to why thoracic aortic aneurysm occurs. Also the causes further depend upon the location of the aneurysm within the aorta. The causes also vary in both the ascending and the descending aorta. The most common cause of thoracic aortic aneurysm is the atherosclerosis, a hardening of the artery damaging the walls of arteries. Though the arteries are soft and smooth from inside, they can develop atherosclerosis as you age. A sticky substance known as atheromatous plaque is formed in the walls of arteries when atherosclerosis develops. This excess plaque in due course of time makes the aorta to become weaker and stiff. The atherosclerosis is more common in people with high blood pressure for a prolonged time, high cholesterol and for those who smoke more than often.
Few of the common causes of the thoracic aortic aneurysm could be due to the reasons mentioned below:
> Changes in body due to aging
> Being overweight
> Aorta getting inflamed
> Accidental injuries
> Genetic disorders like the Marfan syndrome
> Thickening of the arteries known as atherosclerosis
