Pregnancy and Chiari Malformation

Courtney
Was anyone here born with Chiari's and gone through a pregnancy? Some docs I talk to think it's no big deal depending on your severity, others just say "no epi" and they're docs that think the only way to give birth is unconscious and c-section. 
I preferably want to be concious and a natural birth..anyone here been able to do this? Any symptom reoccurrence?
