NCT04865757

Brief Summary

In this study the investigators want to investigate to what extent the application of an artificial bone flape (space flap) influences the success of a decompressive craniectomy. In all participants, a space flap is placed immediately after removal of the skull cap. In a second operation, after 1-3 months, an operation is performed, in which the stored own skull bone is re-inserted. The artificial bone cover is removed at this point.
