Abdominal aortic aneurysm: diagnosis and management

Research recommendations coming out of this guidance

• What are the most effective and cost-effective frequencies for monitoring people with unruptured abdominal aortic aneurysms (AAA) of different diameters, and what is the optimal AAA threshold size (inner-to-inner maximum anterior-posterior diameter on ultrasound) for repair?

• What is the effectiveness and cost effectiveness of complex endovascular aneurysm repair (EVAR) versus open surgical repair in people for whom open surgical repair is suitable for:

  • elective repair of an unruptured AAA or

  • emergency repair of a ruptured AAA?
