The procedure takes about two hours to complete, after which you will be admitted to the hospital overnight for observation. The procedure itself is not painful and occurs while you are awake and comfortable with the use of intravenous sedation. Any discomfort following the procedure is controlled with the use of narcotic analgesia given in timed doses triggered by the patient. Generally, you will receive a full liquid diet the day of the procedure. On the morning following the procedure, you may eat a regular diet and oral medications are substituted for intravenous medications. You will likely be discharged the day following the procedure, and follow up phone numbers and appointments will be given at that time. We recommend that you limit activities for 24-48 hours after discharge, and you may return to work one week following the procedure. Six months after the procedure, you will be scheduled for a follow-up MRI scan to confirm the success of the procedure.
