Background. Data on 230 patients with thoracic aortic aneurysms treated at Yale University … A thoracic aortic aneurysm, an abnormal bulge in a weakened wall of the aorta in the chest area, can cause a variety of symptoms and often life-threatening complications. If the size an aortic aneurysm exceeds 5 centimeters in diameter, then the doctor recommends an immediate surgery to prevent a rupture. 1997 Mar.

Risk of rupture is proportional to the size of the aneurysm. There are several problems with the standard guidelines or “restrictions” for people with a thoracic aortic aneurysm, when it comes to lifting weights. Guidelines for Intervention for abdominal aortic aneurysms. A thoracic aortic aneurysm can develop in the aortic root, the ascending aorta, aortic arch (the section of the aorta in the chest that bends) or descending aorta.
