She can be getting any kind of procedures--ear tucks, chin implant, etc., but my most important question is this... What kind of unusual (the more unusual the better) complication can arise during surgery to put her in danger during the operation? Just during surgery, afterwards she will be fine. I'd really like the danger to come as a consequence or be part of the surgical procedure, rather than an anesthesia reaction.
I've managed to come up with a lot on google for different kinds of surgeries, but not much for my other questions. Any help is hugely appreciated.
