Vicryl (polyglactin 910) mesh as a dural substitute.

P K Maurer, J V McDonald

    Journal of Neurosurgery
    |September 1, 1985
    PubMed
    Summary

    Vicryl (polyglactin 910) mesh shows promise as an absorbable dural substitute. This study found it resorbed with minimal inflammation and no cortical injury in dogs, forming a new membrane.

    Area of Science:

    • Biomaterials Science
    • Neurosurgery
    • Regenerative Medicine

    Background:

    • Dural substitutes are crucial for closing cranial defects.
    • Current materials often cause inflammation or adhesions.
    • A need exists for absorbable, biocompatible dural graft materials.

    Purpose of the Study:

    • To evaluate Vicryl (polyglactin 910) mesh as an absorbable dural substitute.
    • To assess the inflammatory response and tissue integration of Vicryl mesh grafts.
    • To determine the safety and efficacy of Vicryl mesh in closing dural defects.

    Main Methods:

    • Dural defects were created and closed with Vicryl mesh in canine subjects.
    • Macroscopic and histological examinations were performed at various time points.
    • Assessment included graft resorption, adhesion formation, and cortical tissue integrity.

    Main Results:

    • Vicryl mesh demonstrated gradual resorption over time.
    • Minimal cerebromembranous adhesion formation was observed.
    • No injury to the subjacent cortical zones was detected.
    • A significant neomembrane formed over the graft site.

    Conclusions:

    • Vicryl (polyglactin 910) mesh is a viable, absorbable dural substitute.
    • The material elicits a minimal inflammatory reaction.
    • It offers potential for neurosurgical applications requiring dural repair.
