I underwent a surgery in 2013 for the removal of a spinal lipoma (c5/c6). within 14 days, due to a CSF leak, another procedure was performed for the dural closure using a self graft. Till date the CSF leak is ongoing and I am scheduled this week, for a LP shunt and at the same time; the Dural closure due to the CSF leak. Could you advice me of any complications that may occur ? Kind regards Oasis
