Research question


Two trials have been instigated to assess the safety and efficacy of EndoVascular Aneurysm Repair (EVAR) against current standard practice for large abdominal aortic aneurysm (AAA) :

EVAR Trial 1 : A multi-centred randomised controlled trial comparing EVAR and open repair in patients considered fit for open repair.

EVAR Trial 2 : A multi-centred randomised controlled trial comparing EVAR with medical therapy against medical therapy alone for patients considered unfit for open repair.

The early and mid-term results have already been published, but patients are continuing to be followed until 2010 for long-term results.
