    Additional Manufacturer Narrative · 0

    PSEUDOMENINGOCELE IS CONSIDERED SERIOUS BECAUSE IT LED TO A SURGICAL INTERVENTION. SPECIFIC RISK FACTORS HAVE NOT BEEN REPORTED APART FROM VARIOUS LIQUOR CIRCULATION ISSUES. 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, CSF LEAKAGE IS A FREQUENT COMPLICATION FOR DURAPLASTY DUE TO SURGICAL CHALLENGES IN REGARD TO THE ANATOMICAL SITUATION. THEREFORE, TUTOGEN CONCURS WITH THE AUTHORS AND CONSIDERS PSEUDOMENINGOCELE AS NOT RELATED TO TUTOPATCH.
