Hello everyone. I'm new to this great site, but not to AN. Short version, right 3.5 cm AN removed retrosigmod Nov 06 at Barrows. Had a 3.2 cm menningioma removed from my C1, C2 in Jan 06 with no problems. The An however, has been a nightmare. Began leaking 2 weeks post-op from the incision site. I was stitched backup which lasted for a couple months. The leak began again intermittently for the next 2-3 months. Then a surgical screw came out of the site. I had surgery at U of New Mexico hospital, where I live near. The neurosurgeon there said it was a bone infection and not csf. So i was on a pic line for 8 weeks. I began leaking again about 6 months after that. I went through another surgery, where they resealed my mastoid bone, still be living it was an infection, even though my blood work was fine, and i wasn't placed on antibiotics afterward. 6 months after that I leaked again. I got back in touch with my ENT at Barrows, who ordered a technetium bone scan, the results of that showed no infection. So I just came back from Barrows last week. My new neurosurgeon, said it was a csf leak, and wants me back there in a few weeks to place an LP shunt. Hind sites 20 20 , anyone out there had an LP shunt? Please no horror stories, I've lived that long enough. Thanks
