My surgeon was... less than forthcoming about what he found when he was inside. I asked a lot of questions and he seemed genuinely confused as to why I would ask and I don't think he thought I was capable of understanding a real answer so he kept insisting that he fixed the problem. I've requested a copy of my record to include surgical notes so I'll know more at that point but I am fairly certain that my compression was not 100% though it was significant and I did not have collaterals.
