Thoracic Endodovascular Aneurysm Repair (TEVAR)

Thoracic aortic aneurysms are weaknesses of the main blood vessel of the body and originate deep within the chest.  Most often they are not associated with any symptoms, but when symptoms occur, it is associated with severe back pain between the shoulder blades or in the center of the chest.

These "bubbles" on the aorta represent potential areas where the blood vessel could burst or tear.  Rupture of the aorta is a life-threatening situation and requries immediate treatment.  Ideally, the aneurysm is diagnosed and treated prior to rupturing.

TEVAR is a minimally invasive procedure which involves inserting a special stent called an endoluminal graft inside the aneurysm using special x-ray guidance.  This treatment avoids opening the chest and allows for a quicker and less painful recovery.  Not all aneurysms in the chest can be treated with an endoluminal graft but each patient's situation is unique.  New types of stents and techniques are constantly being introduced.  Some aneurysms are not large enough to be treated and are followed with annual or semi-annnual tests.
