Thoracic Aortic Aneurysm

Thoracic Aortic Aneurysm

What is it

The permanent enlargement of some portion of a blood vessel is often described as bulging, ballooning or dilated. The diameter of the enlargement will determine whether or not it is considered an aneurysm. The definition of an aneurysm may also be based on comparison with the normal blood vessel size for an individual. A variation of this defines an aneurysm when the enlarged aorta is at least twice its normal size. Generally, in the majority of patients that part of the aorta that is not enlarged may be used as an indicator of what is normal for that individual.

Whether the aorta is called "dilated" or the word "aneurysm" is used, any enlargement of the aorta, regardless of its size, is an indication of aortic disease and requires treatment. Aortic enlargement, although not yet an aneurysm should be monitored, treated medically, and the lifestyle and diet of the patient addressed.
