Chiari center caloed. now im confused! duraplasty - already done

WI Chiari center called and he needs surgical report. Durplasty concerns is what the person whom called said. I have a bovine patch, so what would be the concern??? If I have one??? Signed release and sent to them. More waiting!

Ok...I'm guessing he couldn't see it on the MRI and was needing to know if I had it??
