Clinical Report: Decompressive Hemicraniectomy in Malignant MCA Infarction

Overview

This meta-analysis evaluates the efficacy of decompressive hemicraniectomy (DHC) in reducing mortality and improving functional outcomes in patients with malignant middle cerebral artery infarction.

Background

Malignant middle cerebral artery infarction is associated with high mortality and poor functional outcomes despite aggressive medical management. Decompressive hemicraniectomy has been studied as a therapy to alleviate intracranial pressure and prevent cerebral herniation.

Data Highlights

Key Findings

• Decompressive hemicraniectomy significantly reduced mortality at 30 days, 6 months, and 12 months.
• Favorable functional outcomes improved significantly at 3 and 6 months post-surgery.
• Older patients (≥60 years) showed similar survival benefits but poorer functional outcomes compared to younger patients.
• Long-term follow-up indicated significant improvements in National Institutes of Health Stroke Scale and Barthel Index scores favoring the surgical group.
• Survival with severe disability did not differ significantly between surgical and medical management groups at 6 or 12 months.

Clinical Implications

The findings suggest that decompressive hemicraniectomy can be a critical intervention for reducing mortality in patients with malignant middle cerebral artery infarction. However, the functional outcomes may vary significantly with age, necessitating careful consideration in treatment planning and patient discussions.

Conclusion

This meta-analysis highlights the sustained mortality benefits of decompressive hemicraniectomy while revealing age-related differences in functional outcomes, informing clinical decision-making in neurocritical care.
