Insights
Decompressive hemicraniectomy significantly reduces mortality for space-occupying hemispheric infarction stroke patients. While reducing deaths, it increases dependency, requiring informed consent regarding long-term outcomes.
Area of Science:
- Neurosurgery
- Neurology
- Critical Care Medicine
Background:
- Space-occupying hemispheric infarction is a severe stroke complication with high mortality (up to 80%) under conservative medical therapy alone.
- Retrospective studies suggested decompressive hemicraniectomy improves survival, but prospective data were needed to confirm efficacy and functional outcomes.
Purpose of the Study:
- To review the indications, surgical techniques, prognostic factors, and clinical outcomes of decompressive hemicraniectomy for space-occupying hemispheric infarction.
- To synthesize evidence from retrospective series and recent prospective randomized trials.
Main Methods:
- Review of retrospective case series and prospective randomized trials on decompressive hemicraniectomy for hemispheric infarction.
- Analysis of mortality rates, functional outcomes, and patient dependency post-surgery.
Main Results:
- Prospective randomized studies confirm decompressive hemicraniectomy significantly reduces mortality (to 20-30%) compared to conservative treatment.
- Mortality reduction is not associated with increased severe disability, but leads to a significant rise in patients requiring assistance.
- Optimal timing and upper age limits for surgical benefit remain areas for further investigation.
Conclusions:
- Decompressive hemicraniectomy is a life-saving intervention for selected patients with space-occupying hemispheric infarction.
- Comprehensive patient and caregiver counseling regarding increased long-term dependency is crucial before surgery.
- Individualized patient assessment and physician experience remain key factors in surgical decision-making.
Abstract:
The development of a space-occupying hemispheric infarction occurs in a subset of patients with ischaemic cerebrovascular stroke. It is a life-threatening condition with a high mortality rate of up to 80% with medical therapy alone. Previous retrospective and uncontrolled case series have suggested that decompressive hemicraniectomy can significantly reduce mortality to 20-30% compared to conservative treatment. This evidence has now been confirmed by the data of prospective randomised studies. The data also indicate that the reduction of mortality is not accompanied by an increase in the number of completely disabled patients. However, the number of disabled patients depending on the assistance of others increases significantly, and the patients and their caregivers need to be comprehensively informed about the long-term consequences prior to surgery. Furthermore, questions concerning the optimal time point for decompression and the upper age limit at which patients still benefit from surgery remain unanswered. Thus the indication for surgery is to a great extent still dependent on the individual situation of the patient and the experience of the treating physicians. This review covers the indications, the surgical technique, the prognostic factors and the clinical outcome with this procedure based on the data of retrospective series and the results of the recently published prospective randomised trials.
