When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair." The word endovascular refers to the area inside of a blood vessel such as the aorta.
NLM Key hole repair (Endovascular Aortic Aneurysm Repair) The main alternative approach to keeping high pressure blood away from the inside of the weakened end artery is to do a keyhole repair. When the abdominal aortic walls are swollen, it's known as abdominal aortic aneurysm. Distally, there must be disease-free zones in the iliac arteries to ensure good leg perfusion and at least one of the femoral arteries should be >8 mm in i⦠J Vasc Surg.
This is known as grafting. No cases were seen of late graft occlusion, stent graft migration, stent fracture, barb fracture, or secondary endoleak. | An AAA can be dangerous if it is not spotted early on. Treatments & Therapies Complications that can happen after endovascular aneurysm repair include leaking of blood around the graft, the graft moving away from its initial placement and the stent breaking. NIH | The neck of the aneurysm must be straight (as opposed to the usual fusiform shape) and longer than 15 mm. An abdominal aortic aneurysm (AAA) is a bulge or swelling in the aorta, the main blood vessel that runs from the heart down through the chest and tummy. The wire frame pushes against the healthy portion of the aorta to seal the device in place. A thin, flexible tube (catheter) is threaded up through the artery and to the site of the aortic aneurysm. Other risks may be possible. Complications that are rare but serious include paralysis, delayed rupture of the aneurysm or infection. With the increasing use of endovascular techniques for abdominal aortic aneurysm repair (EVAR), the frequency of complications from these procedures has risen.
