Abstract

Trauma is the major health problem and is a leading cause of death. Extradural hematomas occur in approximately 2% of all patients of head injuries and 5-15% of fatal head injuries. CT is the single most informative diagnostic modality in the evaluation of a patient with a head injury. Follow-up assessment is frequently necessary to detect progression and stability and evidence of delayed complications and sequelae of cerebral injury which can determine whether surgical intervention is necessary. Hence the present study assess the role of computed tomography in patients with traumatic extradural hemorrhage with neurological correlation and follow up. Objectives of the study: The objectives of the study were to evaluate the imaging findings of extradural hemorrhage on Multidetector Computed Tomography. To correlate the thickness of extradural hemorrhage and midline shift with neurological symptoms of patient. To evaluate the prognosis of patients with neurological deficits on follow up. Material and methods: This was a prospective study involving subjects with traumatic extradural hemorrhage. CT scan Brain was performed in all study participants and neurological correlation and follow-up was done in all subjects. Chi-square used to test significance for qualitative data and an independent t-test was used as a test of significance for quantitative data. p value < 0.05 will be considered as statistically significant. Results: A total of 62 patients were enrolled in the study, majority were in the age group 21 to 30 years. Male predominance 55 (88.7%) was observed. Based on clinical history, clinical diagnosis and mode of injury was due to RTA. Majority of them, 17 (27.4%) of patients had right temporal EDH followed by l3 (21.0%) left temporal EDH and the commonest site of EDH was right temporal region. 26 (41.9%) of patients had mild category of GCS score followed by 22 (35.5%) moderate and 14 (22.6%) had severe category of GCS. The mean size of EDH among study patients was 8.25 ± 3.917 mm with minimum of 3mm to maximum of 18.2mm. Among 36 patients with midline shift, majority, 19 (52.7%) had it on left side and 17 (47.3%) had on right side. The commonest symptom among the patients was loss of consciousness 38 (61.3%). Majority 57 (92.0%) of patients had good recovery followed by 5 (8.0%) had moderate recovery. The size of EDH was significantly larger among patients with midline shift and patients with moderate recovery had significantly larger EDH compared to those with good recovery.
