“The aorta carries blood from the heart to the body. Aortic aneurysms can occur anywhere in the aorta. They may be tube shaped or round.

Aortic aneurysms include:

• Abdominal aortic aneurysm. An abdominal aortic aneurysm occurs along the part of the aorta that passes through the belly area.
• Thoracic aortic aneurysm. A thoracic aortic aneurysm occurs along the part of the aorta that passes through the chest cavity.”

MAYO CLINIC (https://www.mayoclinic.org/diseases-conditions/aortic-aneurysm/symptoms-causes/syc-20369472)

Some people may have both types of aortic aneurysms.

Having an aortic aneurysm increases the risk of developing a tear in the inner layer of the wall of the aorta. This tear is called an aortic dissection.
