Since this is a support forum it would be difficult to speculate on what risks there would be to have the susrgery, but I can say depending on how restricted the CSF flow is and what symptoms u r having it is possible to have risks not having surgery.
The best thing u can do is get to a Chiari specialist and find out.
I am not too familiar with Chiari II except that there is an opening of the spinal cord and that u really need to see the specialist...this can be a frustrating and scarey time....but that is y we r here.
I hope u continue to post ur questions, concerns and share ur chiari experiences with us.
We do have a thread that lists the members drs...please research all drs.
U may want to look at The Chiari Institues web site for more info on the surgery.
