Endovascular stent graft for an aortic dissection

An endovascular stent graft is one way to treat an aortic dissection. A "graft" is a tube made from manmade materials. For this procedure, the doctor makes a cut in a blood vessel at the top of the thigh. He or she puts a folded graft in the blood vessel and threads it up to the damaged part of the aorta. Then the doctor unfolds the graft. This graft does not need to be sewn into place. Blood flows through the graft.
