Key Points

To evaluate the effectiveness of external decompression as a treatment for sylvian hematoma caused by middle cerebral artery aneurysm rupture.
Conducted a series of external decompression procedures
Focused on difficult cases of sylvian hematoma removal
Assessed postoperative intracranial pressure management
External decompression was found to be beneficial in managing sylvian hematoma
Significant reduction in postoperative intracranial pressure was observed
Improved outcomes were noted in cases where sylvian hematoma removal was challenging

Implication

This report demonstrates the effectiveness of external decompression for subarachnoid hemorrhage with sylvian hematoma, suggesting improved outcomes.
