All went well. After a long day of tests and cross matching, he went into surgery this afternoon. Everyone has assumed I am his wife and I didn't correct them. I've been text messaging his daughter in Washington all day long with progress reports. I just asked to sneak into the recovery room to see him and now I think we can all get some sleep.
All good news so far. How exciting! Thank you, thank you to the medical magicians at MUSC for their caring and skill today.
