Familial thoracic aortic aneurysm and dissection syndrome Between 11 and 19 of patients referred for surgery with thoracic aortic aneurysm or dissection have first-degree relatives with either aneurysm or dissection suggesting a familial syndrome without specific identifiable genetic defects.

Dissecting thoracic aortic aneurysm. Location of Aortas and Arteries in the Body Click to Enlarge The aorta is the largest blood vessel in the body. However our modern understanding of the pathogenesis of thoracic aortic aneurysm is quite limited. Thoracic Aortic Aneurysm and Aortic Dissection What is a thoracic aortic aneurysm.

Factors that increase wall stress form the second category and include hypertension and physical trauma. A thoracic aortic aneurysm also called TAA is a bulging weakened area in the wall of the aorta the largest artery in the body resulting in an abnormal widening or ballooning greater than 50 percent of the vessels normal diameter width. Thoracic aortic aneurysm and dissection TAAD affects many patients globally and has high mortality rates if undetected.

Management remains a challenge in elective as well as emergency cases. Learn more about the treatments for a thoracic aortic aneurysm and an abdominal aortic aneurysm. Pain in the jaw neck or upper back.

Aneurysms occur more often in the portion of the aorta that runs through the abdomen abdominal aortic aneurysm. There are two main categories of risk factors for aortic dissection.

Dissecting Aortic Aneurysms Dissecting aortic aneurysms in contrast to nondissecting aortic aneurysms predominantly involve the thoracic aorta either at the beginning of the ascending segment type A or immediately distal to the left subclavian artery at the aortic isthmus type B182267 Their etiology has not been established. This is a tear in the aortic lining. Aortic dissection is when the weakened wall of the aorta tears causing blood to leak between the layers that makes up the wall.

A serious complication of a thoracic aortic aneurysm is an aortic dissection. Aneurysm and dissection are the principal thoracic aortic diseases TADs and they have principles and techniques of surgical treatment in common. Symptoms of a thoracic aneurysm may include.

An aortic dissection starts with a tear in the inner layer of the aortic wall of the thoracic aorta. An aortic aneurysm is a bulging weakened area in the wall of the aorta. When a tear occurs in the innermost layer of the aortic wall blood is then channeled into the wall of the aorta separating the layers of tissues.

Once thought to be solely a degenerative disease that afflicted the aorta due to high pressure and biomechanical stress extensive investigation of the heritability and natural h. The symptoms of aortic dissection include. This can happen suddenly or slowly over time.

In most cases this is associated with a sudden onset of severe chest or back pain often described as tearing in character. The first category is factors that cause medial degeneration of the aortic wall which include genetic abnormalities and inflammatory diseases.
