Sammy's back for the cath right now. It took a LOT of sedation to make him mellow out, and even then, they told us it took a long time after he was back there to knock him out. It breaks my heart to think that he was awake - even if he won't remember it - but that he was awake and we weren't there with him. I promised him we would be there. I'm having a hard time with that.

Update from the nurse - which was so much later than we expected (and only because I was starting to panic and made Jay go ask) because they were having such a hard time getting him to fall asleep: they have a cath in each leg and in one shoulder. They're currently taking pressures and pictures right now, and then they'll look for collateral veins they might need to coil off.

We expect another hour or two before they're done. We'll update when we can.
