Thoracic Surgery (Cardiothoracic Vascular)
A thoracic aortic aneurysm is a ballooning out of a blood vessel in the chest region. In this video, Jason Sperling, MD, director of HealthONE Cardiac Surgery, describes the shape of the aortic aneurysm and where it occurs in the body.

Thoracic aortic aneurysm, or TAA, is an abnormal widening of a part of the thoracic aorta. The thoracic aorta is the large artery (blood vessel) that comes from the heart and extends down the center of your chest. It contains blood with oxygen that goes to the rest of the body. TAA occurs when weak spots in the walls of the blood vessel are present. It commonly forms in the first part of the thoracic aorta but may happen in other parts of the blood vessel.

n the aorta, the central artery that extends from your heart through the center of your abdomen and chest. Certain medical conditions, such as high blood pressure, can weaken the arteries, which deliver oxygenated blood from our heart to the rest of our bodies. The pressure of blood traveling through the arteries can lead to this balloon-like bulge. You can have an aneurysm for years without symptoms or problems. Others can have an aneurysm that pops, which can lead to a stroke if bleeding occurs in the brain. Ruptured aneurysms must be treated quickly, usually within minutes, or it can become deadly: about 50% of all ruptured aneurysms are fatal.
