    Additional Manufacturer Narrative · 0

    THIS REPORT FROM THE SCIENTIFIC LITERATURE REFERS TO THE DEVELOPMENT OF AN ASEPTIC MENINGITIS AFTER CHIARI SURGERY USING TUTOPATCH FOR DURAPLASTY. TUTOPATCH WAS THEREFORE USED IN THIS TRIAL IN AN IN-LABEL CONDITION. DESPITE SEVERAL FOLLOW-UP ATTEMPTS, NO ADDITIONAL INFORMATION WAS PROVIDED FROM THE AUTHORS. MENINGITIS IS CONSIDERED SERIOUS, AS THE PATIENT WAS TREATED WITH STEROIDS. SPECIFIC RISK FACTORS HAVE NOT BEEN REPORTED APART FROM VARIOUS LIQUOR CIRCULATION ISSUES AND THAT THE PATIENT HAS BEEN A SMOKER. THE AUTHORS DESCRIBE THE EVENT AS PROCEDURE-RELATED AND NOT DEVICE-RELATED. BATCH DOCUMENTATION ANALYSIS CAN NOT BE PERFORMED AS THE PRODUCT IDS HAVE NOT BEEN PROVIDED. HOWEVER, ASEPTIC MENINGITIS IS A KNOWN COMPLICATION FOR DURAPLASTY DUE TO AN INFLAMMATORY FOREIGN BODY RESPONSE. THEREFORE, TUTOGEN CONCURS WITH THE AUTHORS AND CONSIDERS ASEPTIC MENINGITIS AS NOT RELATED TO TUTOPATCH.
