Use of self-closing U-clips for dural repair in mini-invasive surgery for herniated disc

Acta Neurochir (Wien). 2008 Oct;150(10):1103-5. doi: 10.1007/s00701-008-0018-2. Epub 2008 Sep 20.


Object: The feasibility of a new technique of dural repair (self-closing U-clips) in mini-invasive surgery for herniated disk is demonstrated in this case report.

Materials and methods: A 44-year-old male patient underwent lumbar microdiscectomy at out Institute, with subsequent dural leak as surgical complication; the dural leak re-appeared even after a second intervention in which we used muscle and dural graft and fibrin glue to repair the leak. We then decided to employ self-closing nitinol- U-clip to achieve primary dural closure.

Results: After the intervention the patient no more presented signs or symptoms due to the unintended durotomy, and the postoperative course was uneventful.

Conclusion: Self-closing nitinol U-clips (Medtronic, Inc., Minneapolis) can be used for closing a dural tear through a mini-invasive approach that could make a conventional microsuturing technique very difficult.
