Long-Term Outcome of Open or Endovascular Repair of Abdominal Aortic Aneurysm

Patients with large abdominal aortic aneurysms were assigned to undergo open surgical repair or endovascular repair. At 6 years, the cumulative survival rates did not differ significantly between groups. The rate of secondary intervention was significantly higher with endovascular repair. Patients with large abdominal aortic aneurysms were assigned to undergo open surgical repair or endovascular repair. At 6 years, the cumulative survival rates did not differ significantly between groups. Randomized trials have shown that endovascular repair offers a perioperative survival benefit over open repair for patients with a large abdominal aortic aneurysm. However, this advantage is not sustained beyond 2 years after surgery. 1 – 4 There is concern that endovascular repair lacks durability, with the possibility of an increased risk of late rupture, 5 and that more reinterventions are required in patients undergoing this technique. Long-term outcome data from these trials are considered to be of crucial importance in deciding which treatment option a patient should be offered. 6 , 7 To date, only limited data beyond 2 years after randomization have been . . .
