[Life-saving hemicraniectomy in acute massive brain infarction]
1Nevrokirurgisk avdeling Rikshospitalet, Oslo.
Summary
Decompressive hemicraniectomy can save lives in patients with severe middle cerebral artery occlusion stroke. This surgical intervention effectively reduces intracranial pressure and improves patient independence, even with neurological deficits.
Area of Science:
- Neurosurgery
- Neurology
- Stroke Medicine
Background:
- Acute middle cerebral artery occlusion causes large ischemic strokes, leading to severe brain edema and intracranial hypertension.
- High mortality rates persist despite medical management due to herniation and circulatory arrest.
Observation:
- A 28-year-old male presented with signs of impending herniation 54 hours after a right-sided middle cerebral artery occlusion.
- Intracranial pressure was elevated (30-40 mm Hg) with neurological deficits including left hemiparesis and right pupil mydriasis.
Findings:
- Right-sided hemicraniectomy significantly reduced intracranial pressure to around 20 mm Hg.
- One year post-stroke, the patient achieved full independence despite residual left hemianopia and hemiparesis.
Implications:
- Decompressive hemicraniectomy is a viable option for selected patients with impending herniation from massive brain infarction.
- Intracranial pressure monitoring is crucial for managing these critical cases.
- This case represents the first reported decompressive hemicraniectomy in Norway for acute massive brain infarction.
