An open aortic aneurysm repair is a surgical procedure to treat an aortic aneurysm, a dangerous bulge in the body's main artery. During the surgery, the aneurysmal segment of the aorta is replaced with a synthetic graft through a large incision in the abdomen or chest. This procedure is performed to prevent the aneurysm from rupturing, which can be life-threatening.

Complex endovascular aortic repair can be necessary in several specific clinical scenarios, usually involving complicated aortic pathology that cannot be adequately managed with standard endovascular techniques. Some common indications include aortic aneuryms extending into the juxtarenal, pararenal or visceral aorta or into the aortic arch, and aortic dissections. Image analysis and preprocessing is absolutely key.

An endovascular aortic aneurysm repair(EVAR) is a surgical procedure to treat an aortic aneurysm, a dangerous bulge in the body's main artery. When the thoracic rather than the abdominal aorta is concerned, the procedure is called TEVAR (thoracic endovascular aneurysm repair). During the procedure, the aneurysmal segment of the aorta is excluded from the circulation by placing and deploying a stentgraft, typically introduced via small incisions in the groin. This procedure is performed to prevent the aneurysm from rupturing, which is an acutely life-threatening event with high mortality.
