What does ascending thoracic aorta mean?
The upward part of the arch, which is the section closest to the heart, is called the ascending aorta. The part of the aorta in the chest is called the thoracic aorta. The portion further down in your trunk is called the abdominal aorta.
What does the descending thoracic aorta do?
Descending Thoracic Aorta The thoracic aorta runs from the aortic arch to the diaphragm, which is the point of separation between the chest cavity and the abdominal cavity. It provides blood to the muscles of the chest wall and the spinal cord.

Is ascending aorta normal?
The normal diameter of the ascending aorta has been defined as <2.1 cm/m2 and of the descending aorta as <1.6 cm/m2. The normal diameter of the abdominal aorta is regarded to be less than 3.0 cm….ANEURYSM FORMATION.

What is a descending aortic aneurysm?
A descending thoracic aortic aneurysm is bulging and weakness in the wall of the descending thoracic aorta, located in the back of the chest cavity. The aorta is the largest blood vessel in the body, and it delivers blood from the heart to the rest of the body.
What are the symptoms of a thoracic aortic aneurysm?
What are the symptoms of a thoracic aortic aneurysm?
- Pain in the jaw, neck, or upper back.
- Pain in the chest or back.
- Wheezing, coughing, or shortness of breath as a result of pressure on the trachea (windpipe)
- Hoarseness as a result of pressure on the vocal cords.
- Trouble swallowing due to pressure on the esophagus.
Does stress cause enlarged aorta?
“The aorta degenerates over time and becomes more dilated, which increases stress on the aortic wall,” Elefteriades said. “Severe physical or emotional stress increases blood pressure to the point where the tensile limit of the aortic tissue is overwhelmed, causing the rupture.”
What is the normal size of an ascending aorta?
The upper normal limit for the ascending aorta is 2.1 cm/m2. A value beyond 4 cm is regarded as an aneurysm, a lower value as ectasia. The normal value for the descending aorta is 1.6 cm/m2 for BSA, and aneurysm is present when a value of 3 cm is exceeded. The aortic diameter gradually increases over time.
What body cavity is the thoracic descending aorta located?
The descending thoracic aorta is a part of the aorta located in the thorax. It is the third and last part of the thoracic aorta and is a continuation of the aortic arch. It is located within the posterior mediastinal cavity, but frequently bulges into the left pleural cavity.
What is the normal thoracic aorta measurement?
Pathophysiology. The normal size for the thoracic and thoracoabdominal aorta is larger than that of the infrarenal aorta, and aneurysmal degeneration in these areas is defined accordingly. The average diameter of the mid-descending thoracic aorta is 26-28 mm, compared with 20-23 mm at the level of the celiac axis.
What is the function of the thoracic aorta?
Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen. The thoracic aorta gives off numerous branches that supply oxygenated blood to the chest cage and the organs within the chest.
