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. Objective This study aimed to evaluate epidemiology, clinical presentations, management, and outcomes of epidural hematoma. Methodology Systematic searches PubMed, Google Scholar, ScienceDirect were performed from database searching for all studies reporting Pooled statistics calculated using measures central tendency spread. The rank correlation test regression test, standard error observed as predictor, are used check funnel plot asymmetry. Results A total 3009 identified, which 95 included with 359 patients. Chronic (CEDH) was more at intracranial level than spinal (91.9% vs 8.1%). average age onset 37.2 ± 4.83 years. cause found trauma ( n = 279; 77.72%) 271 (97.1%) cases head 8 (2.9%) spine. mean delay between first symptoms 13.32 1.73 days 16.38 2.49 level. CT scan constituted main diagnosis tool. lesion predominantly located temporal region lumbar Craniotomy laminectomy most reported treatment option, respectively, outcome commonly uneventful. Correlation tests publication bias assessment show no significant asymmetry high p value 0.8458 0.9596, respectively). Conclusion CEDH related trauma. Its mostly surgical both sites.
