I just opened this thread for the first time a few minutes ago, and boy what a read it was! Pat yourself on the back (if you can reach it!) for providing one heck of a cliff-hanger thread, my friend!
Reading the pre-surgery posts, it seemed like such a routine, safe procedure. Patients are always briefed on the statistical risk factors prior to procedures like the one you had, but you always think the statistics are on your side - and they usually are. In any event, We're all so glad that everything turned out well in the end, even if the ride itself proved a bit more than you bargained for.
Kudos to your wife, too! Sounds like you owe her one.
Take care and stay strong,
