The Efficacy and Safety of a Latest Dural Substitute

Official Title

A Prospective, Multi-center, Randomized, Parallel-controlled Clinical Trial Evaluating the Efficacy and Safety of Lyoplant Onlay in Repairing Cerebral Dura Mater

Brief Summary

      This prospective, multi-center, randomized, parallel-controlled clinical trial was designed
      to evaluate the efficacy and safety of Lyoplant Onlay in repairing cerebral dura mater.
      DURAFORM was regarded as the control group. a total of 80 patients were randomized into
      experimental and control group (1:1).Data were collected on complications resulting in CSF
      leaks, surgical site infections, instrument performance parameterized other neurological
      complications within 30 days. Surgeons also provided data on the ease of use of the dural
      sealing techniques, as well as preparation and application times. The above-mentioned date
      were used to evaluate the efficacy and safety of Lyoplant Onlay .
