Abstract

Objective
Chronic subdural hematoma is relatively common in old age. However not all patients develop chronic subdural hematoma after head trauma. We evaluate the risk factors of chronic subdural hematoma after head trauma in old ages.
Methods
Thirty-three head trauma patients over 70 years old, who developed chronic subdural hematoma after head trauma, participated in the study from January 2011 to December 2013. On the other hand, we included 34 head trauma patients who did not developed chronic subdural hematoma after head trauma at the same period as control group. We investigated risk factors that related with development of chronic subdural hematoma after head trauma prospectively.
Results
Brain atrophy is most related factors in development of chronic subdural hematoma after trauma (p=0.000). Male patients (p=0.001) were also associated with progression to chronic subdural hematoma after head trauma.
Conclusion
We should consider the head trauma patients with risk factors for developing chronic subdural hematoma.
