Aortic Aneurysm - Classification

Classification

Aortic aneurysms are classified by where on the aorta they occur; aneurysms can appear anywhere.

• If found in the arch portion of the vessel, it may be known as Tatatatum's Aneurysm.
• An aortic root aneurysm, or aneurysm of sinus of Valsalva, appears on the sinuses of Valsalva or aortic root.
• Thoracic aortic aneurysms are found on the thoracic aorta; these are further classified as ascending, aortic arch, or descending aneurysms depending on the location on the thoracic aorta involved.
• Abdominal aortic aneurysms, the most common form of aortic aneurysm, are found on the abdominal aorta, and thoracoabdominal aortic aneurysms involve both the thoracic and abdominal aorta. There are other classifications that might help treatment.
