Selected conditions affecting the thoracic and abdominal aorta can be treated using endovascular techniques that avoid large surgical incisions. Through a catheter inserted into the blood vessels, specialised stent grafts are positioned within the diseased segment of the aorta to reinforce the vessel wall and restore normal blood flow.

These procedures are commonly considered for appropriately selected patients with aortic aneurysms and other aortic disorders, offering reduced postoperative discomfort, shorter hospital stays and faster recovery compared with conventional surgery.
