Surgical Interventions for Significant Hematomas
Surgical management of significant hematomas varies by location, with cerebellar hemorrhages >3 cm requiring urgent surgical evacuation, while supratentorial hematomas may benefit from minimally invasive approaches or decompressive craniectomy in select cases. 1
Intracerebral Hemorrhage (ICH)
Supratentorial ICH
- Early hematoma evacuation has not shown consistent benefit in large randomized trials for most supratentorial ICH patients 1
- Surgical intervention may be considered in specific circumstances:
Cerebellar ICH
- Surgical evacuation is strongly recommended for cerebellar hemorrhages >3 cm in diameter or those associated with brainstem compression or hydrocephalus 1
- Attempting to control ICP via ventriculostomy alone is insufficient and potentially harmful, particularly in patients with compressed cisterns 1
- The perceived life-saving benefits of surgical evacuation for cerebellar ICH have prevented randomized trials comparing surgery versus conservative management 1
Decompressive Craniectomy
- May be considered to reduce mortality in patients with:
- Coma (GCS score <8)
- Large hematomas with significant midline shift
- Elevated ICP refractory to medical management 1
- The effectiveness of decompressive craniectomy for improving functional outcomes remains uncertain 1
- No clear differences have been demonstrated between decompressive hemicraniectomy with and without clot evacuation 1
Subdural Hematomas
- Rapid surgical intervention is required for patients with acute subdural hematomas who present with deteriorating neurological function 3
- The subdural evacuating port system (SEPS) provides a minimally invasive technique that can be performed at bedside, which may be especially useful in areas with limited neurosurgical coverage 3
Epidural Hematomas
- Standard management has traditionally mandated prompt evacuation of all epidural hematomas 4
- Small epidural hematomas in asymptomatic patients may be managed conservatively with careful observation and repeat imaging 4
- Risk factors for subsequent deterioration requiring surgery include:
- Skull fracture traversing a meningeal artery, vein, or major sinus
- Early diagnosis (<6 hours after trauma) 4
Special Considerations
Coagulopathy Management
- Preoperative coagulopathy correction is crucial before surgical evacuation 5
- In patients with thrombocytopenia (<100 × 10^9/L), emergent craniotomy can be successful but prognosis may still be poor due to severe cerebral edema 5
Timing of Intervention
- For patients with significant midline shift, large hematomas, or ICP refractory to medical management, early surgical intervention should be considered 1
- In cases of cerebellar hemorrhage with brainstem compression or hydrocephalus, immediate surgical evacuation is recommended 1
Emerging Surgical Approaches
- Minimally invasive techniques are increasingly used for supratentorial ICH and include:
- Stereotactic aspiration and thrombolysis
- Endoport-mediated evacuation
- Endoscopic aspiration 2
- These approaches may facilitate significant hematoma volume reduction with potentially less morbidity than conventional open surgical approaches 2
