What is her current prognosis?

Why was he not notified?

Any other doctor would have likely done essentially the same.

Anything permanent and debilitating?

As a direct result of the above?

I believe my own mother's life was shortened (or at least its final days were made miserable for many) by two egotistical surgeons whose work caused her to spend the last four months of her life hospitalized (and even pushed to a lesser facility as insurance benefits were diminished) following what I believe was a botched surgery. However, I am sure those doctors have documentation proving she had agreed/consented to face the dangers of certain possible complications and even death.

I have a truckload of empathy toward you and your mother, but I believe you would have to be able to prove the doctor wittingly did *not* do something he already knew he *should* have done (or should have done differently), and then you would likely also have to show permanent harm in the form of impairment or disability resulting in significant loss of something tangible or else an added burden of some kind of great financial expense or stress.
