Introduction
A thoracic aortic aneurysm (TAA) is the ballooning of the thoracic aorta, which is the main artery located within the chest cavity. The normal diameter of the aorta, the body's largest artery, is approximately 3.5 cm; exceeding this diameter can lead to serious health problems. Thoracic aortic aneurysm carries potentially life-threatening risks, and therefore, early diagnosis and treatment are of great importance.
Importance of Thoracic Aortic Aneurysm
A thoracic aortic aneurysm occurs as a result of the weakening and enlargement of the aortic wall. When the enlargement reaches a certain level, the risk of rupture of the aneurysm arises. In the event of rupture, life-threatening conditions such as sudden bleeding and shock can develop. The mortality rate for a ruptured aneurysm before reaching the hospital is quite high.
Symptoms
Thoracic aortic aneurysm often does not cause symptoms. Growth without rupture can usually create a feeling of discomfort by pressing on adjacent organs. However, in the event of rupture, the following symptoms may occur:
