dural repair
Surgical closure of inadvertent or intentional openings in the dura mater during spinal procedures.
Full Definition
The surgical technique used to close tears or openings in the dura mater, the outermost membrane covering the spinal cord and nerve roots. Dural tears can occur inadvertently during decompressive procedures or may be created intentionally for tumor removal or cyst drainage. Repair techniques include primary suturing with non-absorbable sutures, patch grafting with autologous fascia or synthetic materials, and the use of tissue sealants or fibrin glue. Proper dural repair is essential to prevent cerebrospinal fluid leak, pseudomeningocele formation, and potential infection.
Usage
Usage note: Specify technique used (primary suture, patch graft, sealant) in documentation.
