Your poor friend...but afaik, a post-operatic haemorrage after a tonsillectomy is still something which carries a significant risk.
I remember that there had been two deaths in Austria in the early 2000s due to complications from tonsillectomy. There were reports in the media then.
And may God rest the soul of the victim.
P.S.: sorry, I meant both Ms Correya and the others who died.
