Not questioning the fitness of the OP, but those were images found on the inter webs indicating where the scar is. They are not selfies. At least that’s what I read.
Only odd new scar I had was about three inches horizontal near my right shoulder. Also told they used this for the heart lung machine due to the aneurysm repair.
They shaved legs for access to blood vessels in case they are needed. First I’ve heard of them cutting the access open just in case. I know the OP is a couple months old, but that’s my two cents anyway.
