Question Title: Brain Malformation

It is difficult to tell you whether or not you will walk again. The goal of
surgery for an AVM is to completely remove the lesion. If the surgeons were
able to remove the AVM, the risk for problems from that AVM is gone. However,
surgery in the brainstem can be tricky as all the neural connections from
the brain to the rest of the body are contained in a small area.

It sounds like you may have had a small infarct in the brainstem from surgery,
which can happen. If it is indeed the case that you have had some injury to
the brainstem that made you weak after surgery, it is doubtful you will be
able to walk again. At three years after surgery you will have seen the majority
of improvement after such an injury to the brainstem. The best way to see
the degree of injury to the brainstem is with an MRI, which may have already
been done.

The answer given is speculative based on the limited information given. You
need to speak to your surgeon regarding the nature of your inability to walk
in relation to the previous surgery for the AVM. Get some clear answers that
you can understand.

Good luck.
