Background and Objective: Traumatic brain injury is
one of the most significant problems worldwide.
Major causes of head injury are caused by traffic
accidents and fallings. In mild traumatic brain injury,
consider that there are risk factors for abnormalities
in the brain. However, there is a lack of study in risk
factors for neurosurgical intervention related to
abnormal CT findings in Thai people.
Method: Retrospective descriptive study in the patients
diagnosed mild traumatic injury (GCS 13-15),
with high risk for abnormalities in CT scan. The outcome
of the study is to admeasure the ratio of abnormal
CT findings and to determine factors that
affected abnormal CT findings.
Results: There were 117 mild traumatic brain injury
– high-risk patients performed a CT scan. Of those, 41
patients (35%) had abnormal CT findings. Two significant
factors affecting abnormal CT findings; GCS 13-14
after observation and signs of open/base of skull
fractures with a number of 5 (p=0.011) and 5 (p=0.037),
respectively.
Conclusion: Open skull or base of skull fracture and
GCS of 13-14 observation were the most two strongest
predictors for abnormal CT scan in mild traumatic
brain injury – high-risk patients.
