Endovascular repair of a thoracic aortic aneurysm

This drawing shows an aneurysm in the descending thoracic aorta. The doctor makes a cut in a blood vessel at the top of the thigh and inserts a folded graft. Then, they thread the graft up to the bulging part of the aorta and unfold it. This type of graft does not need to be sewn into place. Blood flows through the graft.
