Repair of Aortic Arch Dissection

Thoracic Aortic Aneurysm

The most frequent cause of Aortic Aneurysms is atherosclerosis. Major risk factors include a high level of LDL cholesterol, smoking, and diabetes. The arterial wall thins as result of destruction of the media and a localized dilatation occurs (aneurysm).

You can see the aneurysm here as a bulge in the thoracic aorta. Atherosclerosis is usually more severe distally in the aorta, perhaps because the blood flow might be more turbulent here. So most atherosclerotic aneurysms occur in the abdomen, although the pulse pressure is actually higher in the chest.

Advanced syphilis, the classic cause of thoracic aortic aneurysms, is thankfully uncommon today.

Heart Bypass Surgery (CABG)

This 3D medical animation of the heart shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease.
Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating.
A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.


This is similar to the procedure performed on former president Bill Clinton and California governor (movie star) Arnold Schwarzenegger.
