Hi, has any of you experienced continued leakage of CSF after your operation and if so has any of you had to have a cerebral shunt? I would very much appreciate if you could share with me. My husband had his AN operation 2 weeks ago and has been struggling with CSF leakage from wound. He has had a lumbar drain for four days, a 36 hours break from drain and now lumbar drain has been switched on again. Doctors are discussing a cerebral shunt. I have tried to find information about same, all very bleak, but none referring to AN and mostly referring to children. Please let me know good and bad. Thank you on advance!
