Val av OAR eller EVAR vid buk­aorta­aneurysm är inte givet - Randomiserade studier har utvärderat öppen och endovaskulär kirurgi – ingen av metoderna är i allt överlägsen den andra.

Endovascular or open surgery for elective abdominal aortic surgery? Evidence from the 5 randomized trials OAR (open aortic repair) can be demanding for fragile patients, but has good long-term durability. EVAR (endovascular aortic repair) is more lenient, but is associated with life-long controls, more life-threatening reinterventions, a remaining threat of rupture and a possibly increased risk of death by cancer. All patients with an AAA (abdominal aortic aneurysm) must recieve a thorough evaluation of medical risk and expected survival before open/endovascular treatment and a discussion of the short- and long-term risks of the different treatment alternatives.
