There are no data available on the risk of intraoperative bleeding during decompressive craniectomy (DC) after traumatic brain injury (TBI) in children. The objectives of this study were to assess the risk of intraoperative bleeding during DC for intractable intracranial hypertension after TBI, to identify potential factors associated with the risk of bleeding during DC, and to assess the impact of DC on systemic and cerebral hemodynamics and on coagulation. ⋯ DC allows a significant decrease in ICP after severe pediatric TBI but is a surgical procedure at a high risk of bleeding. High ICP and INR during the immediate preoperative period are the main factors associated with increased IBL during DC. Further studies are needed to confirm our results and to assess the impact of the amount of IBL on the postoperative survival and functional outcome.

Case series (CS) are well-known designs in contemporary use in neurosurgery but are sometimes used in contexts that are incompatible with their true meaning as defined by epidemiologists. This inconsistent, inappropriate and incorrect use, and mislabeling impairs the appropriate indexing and sorting of evidence. ⋯ A distinction between a case report, case series, and descriptive cohorts is absolutely necessary to enable the appropriate indexing, sorting, and application of evidence. Researchers need better training in methods and terminology, and editors and reviewers should scrutinize more carefully manuscripts claiming to be "case series" studies.
