Background: Subdural hematomas (SDH) can occur in one in three people with severe head injuries. Subdural hematomas are increasingly being found with age. Study of correlation of histopathological changes in hematoma and radiological contents of cases of subdural hematoma are still very limited. 

Objective: In this research, SDH histopathological changes are expected to be a reference and consideration in the next invasive therapeutic action. This study also aims to look for other approaches in determining the therapeutic actions in acute subdural hematomas by comparing the clinical, radiological, and histopathological profiles of blood deposits from subdural hematomas

Methods: This study is a clinical observational study with a cross sectional study approach. Primary data were obtained from all subdural hematoma patients. CT Scan was performed and the results were read by Radiologists. Hematoma blood samples was analysed microscopically and morphologically by Pathologist at our hospital.

Results: The average value of CT Scan blood reading density of Chronic SDH patients in RSUD Dr. Soetomo which was operated on in 2018-2019 was 31.30 (± 11.47) HU with the smallest value of 4.0 and the largest 54 HU. Average day of events was 36 ± 36.66 days with the shortest occurrence day 12 days and the longest 150 days. There is an influence between the CT Scan reading density and the day of the incident. The calculation results obtained a negative correlation (r = -0.814; p <0.001) between the CT Scan density value and the day of occurrence. Statistical calculation of the coefficient B0 for the dependent variable (day of occurrence) is 147.557 and the coefficient of B1 for the HU value from the CT Scan reading is -3.417. In this study, the histology generally did not represent chronic SDH readings specifically.

Conclusion: There’s a negative correlation between the number of incident days with the CT Scan density where the longer the event day the lower the CT Scan density value.
