This study analyzed the epidemiology of adult cases
with minor head trauma in order to identify the high risk groups for
scanning by cranial computed tomography (CT).
Patients and Methods: We conducted a prospective
observational study. This included 450 patients who had been seen
at our Emergency Clinic and had experienced a minor head trauma
between January 2012 and March 2012.
Results: One hundred and twenty six (28%) of the patients were
women and 324 (72%) were men. The mean age was 40.99±17.87
years. Leading trauma mechanisms were motor vehicle accidents,
followed by falls and violence. Accidents not involving vehicles
and violence were the most frequent causes for trauma in patients
with a skull fracture; falls from a height were the most common
cause in patients with traumatic brain injury (TBI). Cranial CT
scans were performed in 73.6% (n=331) of the cases. Among
CT scans, 13% were interpreted as abnormal. The most frequent
abnormal CT findings included linear fracture (34.9%), subdural
hematoma (25.6%) and subarachnoid hemorrhage (16.3%).
Conclusion: The Glasgow coma scale (GCS) score of 14,
vomiting more than 3 times and scalp laceration were predictors
for a high risk of an abnormal cranial CT. There was no statistically
significant relationship between an abnormal CT scan and gender,
cause of trauma, complaints at presentation other than vomiting
more than 3 times, physical examination findings other than scalp
laceration, alcohol or anticoagulant use.
