Overview

Thoracic aortic aneurysms are relatively uncommon (6 to 10 new ones per 100,000 person years) and are less prevalent than abdominal aortic aneurysm. Thoracic aortic aneurysms are generally diagnosed after the sixth and seventh decades of life. Although men are affected 2 to 4 times as often as women, women are at higher risk of rupture by a factor 6.8.

Epidemiology and Demographics

• TAAs are relatively uncommon with an estimated incidence between 6 and 10 new aneurysms per 100,000 person-years. According to a study by Beckerstaff et al., the incidence of thoracic aortic aneurysms was reported to be 5.3 per 100,000 per year. Another study done by Clouse et al. showed the incidence to be 10.4 per 100,000 per year.
• However, the incidence and prevalence of TAD has been increasing in the past years. The annual number of surgeries performed on the aorta have increased, along with improved post- surgical and long term survival.

Age

• TAAs are usually diagnosed after the sixth and seventh decade of life.

Gender

• Males are affected approximately two to four times more often than females.

Race

• Thoracic aortic aneurysm is more common in caucasians.
