dural tear
Inadvertent perforation of the dura mater during spinal surgery, requiring immediate repair.
Full Definition
A dural tear is an accidental perforation or laceration of the dura mater, the tough outer membrane that surrounds the spinal cord and nerve roots. This complication can occur during various spinal procedures, particularly those involving decompression or revision surgery where scar tissue may make the dura more adherent to surrounding structures. Dural tears result in cerebrospinal fluid leakage and must be identified and repaired promptly to prevent complications such as persistent CSF leak, headaches, infection, or nerve root herniation. Repair techniques include direct suturing, patch grafting, and the use of dural sealants.
