Decompressive Craniectomy in Spontaneous Intracerebral Hemorrhage: A Case-Control Study

Area of Science:

• Neurosurgery
• Critical Care Medicine
• Neurology

Background:

• Decompressive craniectomy is an emergency procedure to reduce intracranial pressure.
• Limited large-scale studies exist comparing decompressive craniectomy to best medical therapy.
• This study investigates survival and functional outcomes for decompressive craniectomy in spontaneous intracranial hemorrhage.

Purpose of the Study:

• To evaluate the survival and long-term functional outcomes of decompressive craniectomy versus best medical treatment for spontaneous intracranial hemorrhage.
• To compare mortality rates and functional recovery between the two treatment groups.

Main Methods:

• Retrospective matched-cohort study of 54 decompressive craniectomy patients and 72 best medical treatment patients.
• Patients had spontaneous supratentorial hemorrhage.
• Outcomes (survival, Glasgow Outcome Scale) analyzed at multiple time points up to 12 months.

Main Results:

• Decompressive craniectomy showed significantly higher survival rates at 30 days, 6, and 12 months (70-76%) compared to medical treatment (52-60%).
• No significant difference in functional outcomes was observed between groups at any time point.
• Decompressive craniectomy led to longer hospital stays and more frequent adverse events like pneumonia and UTIs.

Conclusions:

• Decompressive craniectomy significantly improves survival in spontaneous intracranial hemorrhage patients.
• This survival benefit is associated with increased hospital stay and adverse events.
• Functional outcomes were not improved by decompressive craniectomy compared to best medical treatment.
