1316 Chronic Epidural Hematoma: A Systematic Review and Meta-Analysis

Abstract Background Epidural hematoma constitutes a common condition in neuro-traumatology. If its acute form is well known, the chronic one remains less described. In this study, we aimed to evaluate epidemiology, presentations, management, and outcomes of epidural (CEDH). Method Systematic searches PubMed, Google Scholar, ScienceDirect were performed from database searching for all studies reporting CEDH. Pooled statistics calculated using measures central tendency spread. Results Totally, 3009 identified, which 95 included with 359 patients. CEDH was more intracranial than spinal (91.9% vs 8.1%). The average age onset 37.2 +/- 4.83 years. cause found trauma (n = 279; 77,72%) 271 (97.1%) cases head 8 (2,9%) spine. median delay between first symptoms 13.31 3.43 days level 16.37 5.87 level. CT-scan constituted main diagnosis tool. lesion predominantly located temporal region at lumbar Craniotomy laminectomy most reported treatment option respectively outcome commonly uneventful. Correlation Regression test publication bias assessment show no significant Funnel plot asymmetry high p-value (p 0.8458 p 0.9596, respectively). Conclusions There clear risk factor mostly surgical.
