The aorta is the largest arterycarrying oxygenated blood away from the heart to all parts of the body. Sometimes this aorta gets enlarged due to the weakness of the artery walls, leading to a condition known as an aneurysm. This aneurysm can develop anywhere along the aorta. A particularly important aneurysm ic called the Thoracic Aortic Aneurysm (TAA).
Thoracic Aortic Aneurysm (TAAs)
An aneurysm that occurs in the aorta located in the chest area is known as a thoracic aortic aneurysm. As an aneurysm can lead to a tear in the wall of the artery, it is also called as a thoracic aneurysm and aortic dissection, which leads to life-threatening bleeding.
The artery walls in the aorta weaken and get expanded or bulged. The balloon or bulging of the artery wall may be defined as a fusiform (uniform in shape) or a saccular (appears as lop-sided blister on one side of the aorta) aneurysm. Saccular aneurysm forms in the weakened area of the aorta wall.
Classification of TAAs
TAAs are classified into three groups depending on the location. They are:
Symptoms of TAAs
TAAs may be asymptomatic or symptomatic. The symptoms may be related to the size, location, and growth rate of an aneurysm. It often grows slowly without any symptoms, making it difficult to detect. If you experience pain with TAAs, then it may be a life-threatening medical emergency.
Symptoms of ascending TAAs include:
Symptoms of aortic arch or descending TAAs include:
The symptoms of the TAAs may resemble the other conditions. So, go for a regular health check-up. This can help you get early diagnosis and treatment.
