Background: Traumatic brain injury (TBI) is damage to the head caused by an external physical attack/impact. Deaths that occur from brain injury are 14-30 out of 100,000 population each year. TBI is diagnosed using Computed Tomography (CT) as the gold standard. Different densities of the pathological feature on CT can be measured by Hounsfield Unit (HU) to define its pathology. We try to asses if the HU can predict the hematoma expansion in TBI.
Methods: This research is an observational study. The data is taken from the radiology installation data of the emergency care installation at the Dr. Soetomo Regional General Hospital regarding factors that play a role in hematoma expansion with related factors in patients with subdural and epidural bleeding. Data were taken from January 2021 to December 2021. The factors analyzed were Hounsfield Unit, age, and hemostasis factors.
Results: In this study, there were 30 patients. This study was dominated by men (73.00%) and the age group of 16-20 years (26.6%). The mean PTT value in this study's subjects was 13.3±3.27. The mean value of APTT is 29.8±2.82. The average Hounsfield Unit is 43.60±5.82. No significant relationship was found between Houndsfield Unit, Age, APTT level, and age with hematoma expansion. A significant relationship was found between PTT and hematoma expansion. Simultaneously Hounsfield Unit, PTT, APTT, and age had a significant relationship with hematoma expansion.
Conclusion: There was no statistically significant relationship between Hounsfield Unit and hematoma expansion. There is a statistically significant relationship between PTT and hematoma expansion. Simultaneously found a significant relationship between Hounsfield Unit, PTT, APTT, age, and bleeding activity.
