| Abstract |
Objective
Chronic subdural hematoma (CSDH) can be easily diagnose and treated, but have relatively high recurrence. Through magnetic resonance image (MRI) increases, gained MRI of CSDH have been larger. But there is little information in MRI patterns of elderly patients compared with that of non-elderly patients. So we analyze MRI patterns of elderly patients and also examined whether preoperative MRI patterns can predict CSDH recurrence.
Methods
We retrospectively analyzed the data of patient with CSDH treated with burr hole trephination and evaluated preoperative MRI from January 2005 to December 2014. We defined CSDH recurrence as the reaccumulation of hematoma on the operated side within 3 months after surgery with reappearance of symptoms such as severe headache, hemiparesis or dizziness.
Results
There were total 77 hematomas of 64 patients were treated with burr hole trephination. Heterogeneous MRI patterns were larger in elderly group (p=0.001). Overall recurrence rate was 10.4%. The recurrence rate of the iso/hypointensity group on T2WI was significantly higher than that of the other groups combined (29.4% vs 5% p=0.011).
Conclusion
In this study, we confirmed that heterogeneous MRI patterns were larger in elderly patients. And, the CSDH recurrence rate was high in the T2 iso/Hypointensity group based on preoperative MRI findings. |
