you found out that a very very rare condition does in fact happen, even to what the writer herself refers to as one of the very best in the field?
This is true of EVERY surgery. It's true that all the pitfalls of aftercare she notes are not the same for every surgery - but the actual incidence of a rare complications is there for every sort of surgery including much less invasive ones.
Everything in life has risks.
The writer makes a good case for improving the after-care process (and the training and certification process) but I don't think it's news that there are sometimes complications (fortunately, seldom as devastating as that one)
