The descending aorta travels down the chest and becomes the abdominal aorta when it crosses the diaphragm, at about the twelfth thoracic vertebra. A thoracic aortic aneurysm is located in the chest area. It is also known as descending thoracic aorta or simply thoracic aorta. A linear regression model was built to test the effect of age and gender on tortuosity. The aorta is located at different parts of the body. Trouble swallowing due to pressure on the esophagus. It lies on the left side of the vertebral column in the upper part of the posterior mediastinum. [2] It occurs due to the intrinsic weakness of the aortic wall.

It is located within the posterior mediastinal cavity, but frequently bulges into the left pleural cavity. The thoracic aorta, the part of the aorta that runs from the arch of the aorta to the diaphragm, gives off numerous branches that supply oxygenated blood to the chest cage and the organs within the chest. Aorta is the biggest blood vessel of humans and it is responsible to deliver blood from a person's heart to . The descending thoracic aorta (DTA) was analyzed and was divided into four zones of equal length. Aneurysm of the thoracic aorta is less common than in the abdominal aorta, but it is clinically important because of the risk of rupture and death.
