T/F

True

Possible familial predisposition  with chromosome 19q13

3


Aneurysm developement hs been proposed as a result of elastin and collagen break down from

elective repair should be under gone in what tpes of Pts


aneurysms 2x the size of the aorta

those with rapid expansion . 0.5 cm in 6 mths

22


ASA is it detremental to use with a AAA


no data suggest it contributes to expansion or initiation of rupture

Long term statin use has shown decreased mortality in those who have undergone AAA repair?

T/F


True

24


Two approaches to AA repair are


Retroperitoneal or transabdominal
