Summary
Surgical decompression for space-occupying hemispheric infarction significantly reduces death and improves outcomes. This benefit appears consistent across most patient groups, though timing and elderly patient outcomes require further study.
Area of Science:
- Neurosurgery
- Neurology
- Clinical Trials
Background:
- Space-occupying hemispheric infarction poses a significant risk of mortality and poor functional outcomes.
- Surgical decompression is a potential intervention, but its efficacy across diverse patient populations remains under investigation.
Purpose of the Study:
- To evaluate the effectiveness of surgical decompression in reducing mortality and improving functional outcomes in patients with space-occupying hemispheric infarction.
- To determine if patient characteristics modify the treatment effect of surgical decompression.
Main Methods:
- A systematic review and meta-analysis of randomized clinical trials comparing surgical decompression with conservative treatment.
- Data from 7 trials involving 488 patients were analyzed using mixed-effect logistic regression, adhering to PRISMA guidelines.
Main Results:
- Surgical decompression was associated with a significantly decreased risk of death (aOR, 0.16; 95% CI, 0.10-0.24) and an increased likelihood of favorable outcomes (aOR, 2.95; 95% CI, 1.55-5.60).
- Treatment effects were consistent across most prespecified subgroups, including age, sex, stroke severity, and vascular territory.
Conclusions:
- Surgical decompression offers consistent benefits for patients with space-occupying hemispheric infarction.
- Further research is needed to clarify the benefits of surgery for patients treated more than 48 hours after stroke onset and for elderly individuals.
