Insights
This study details radical craniotomy for organized chronic subdural hematoma (CSDH) in elderly patients. A novel technique involving dura mater stripping and fibrin glue obliteration prevented recurrence in all three cases.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Organized chronic subdural hematoma (CSDH) presents a surgical challenge, particularly in recurrent or complex cases.
- Previous treatments like trephine evacuation may be insufficient for organized CSDH.
Observation:
- Three elderly patients (two male, one female) with organized CSDH were treated.
- Two patients had a history of intracranial aneurysm surgery (craniotomy and neck clipping).
- Multiple prior trephine evacuations had failed to resolve the organized hematoma.
Findings:
- Radical treatment via craniotomy and complete hematoma removal, including the thick outer membrane, was performed.
- A surgical technique involving stripping the dura mater and securing it with fibrin glue was employed to obliterate the subdural space.
- No recurrences were observed during a follow-up period exceeding two years.
Implications:
- This surgical approach offers a potentially effective solution for complex, organized chronic subdural hematomas.
- The dura mater manipulation technique may reduce the risk of CSDH recurrence.
- Further research into this radical treatment for CSDH is warranted.
Abstract:
We reported 3 cases of organized chronic subdural hematoma (CSDH), which required radical treatment by craniotomy. All patients were in the 70s (male, two; female, one). Two cases had previously received craniotomy and neck clipping for intracranial aneurysm. All of them received trephine evacuation of hematoma more than two times, although the hematoma was not removed due to organization. Because of this, we performed craniotomy and removal of the hematoma with its thick outer membrane. In order to obliterate the subdural space completely, we stripped the dura mater from the skull and attached it to the inner membrane with fibrine glue. After a period of more than two years of followed-up, no recurrences had been discovered.
