Surgical treatment of spontaneous cerebellar hemorrhage
Insights
Suboccipital craniectomy is the most effective surgical treatment for spontaneous cerebellar hemorrhage, offering improved outcomes for patients, including those who are deeply comatose. Early intervention can lead to better functional recovery.
Area of Science:
- Neurosurgery
- Neurology
- Critical Care Medicine
Background:
- Spontaneous cerebellar hemorrhage constitutes 5%-10% of all intracerebral hemorrhages.
- Typical symptoms include sudden severe headache, vomiting, dizziness, and gait instability.
- Disturbances in consciousness often present as a late symptom.
Purpose of the Study:
- To evaluate the effectiveness of surgical interventions for spontaneous cerebellar hemorrhage.
- To identify optimal surgical indications and patient outcomes.
- To analyze mortality rates associated with different surgical procedures.
Main Methods:
- Retrospective analysis of 26 surgical cases of spontaneous cerebellar hemorrhage treated between June 1979 and June 1983.
- Surgical indications included impaired consciousness, signs of brainstem compression, and hematoma size >3 cm.
- Procedures included suboccipital craniectomy with or without ventriculostomy, and ventriculostomy alone.
Main Results:
- Overall surgical mortality was 34.6%.
- Suboccipital craniectomy yielded a mortality rate of 27%, while ventriculostomy alone had a 75% mortality rate.
- Causes of death included brainstem failure, airway obstruction, chest infection, and renal failure.
Conclusions:
- Suboccipital craniectomy is the most effective surgical procedure for indicated cases of spontaneous cerebellar hemorrhage.
- Among survivors, 31% returned to work, 38% had moderate disabilities but were self-sufficient, and 31% remained dependent.
- Early surgical intervention may benefit deeply comatose patients.
Unlabelled:
Spontaneous cerebellar hemorrhage accounts for 5%-10% of intracerebral hemorrhage in most series. From June 1979 to June 1983 we had 26 surgical cases of spontaneous cerebellar hemorrhage. There were 15 men and 11 women. The typical history was sudden onset of severe headache, vomiting, dizziness, and inability to walk. Disturbance of consciousness was usually a late feature. Common signs were truncal ataxia, nystagmus, conjugate eyeball deviation, small miotic pupils with or without light reflex and abducens palsy. Surgical indications are (a) disturbance of consciousness, (b) signs of brainstem compression and (c) hematoma with transverse diameter greater than 3 cm. The overall surgical mortality was 34.6%. Twenty-two patients underwent suboccipital craniectomy to evacuate hematomas with or without ventriculostomy; mortality rate was 27%. Four patients underwent ventriculostomy only; mortality was 75%. Causes of death were (a) brainstem failure, six patients; (b) airway obstruction, one patient; (c) chest infection, one patient; (d) chronic renal failure, one patient.
Conclusion:
(a) suboccipital craniectomy to evacuate the hematoma is the most effective procedure where treatment is indicated; (b) the clinical recovery of the survivors show that 31% return to work, 38% are moderately disabled but take care of themselves, and 31% remain dependent on others; (c) deeply comatose patients may still benefit from early operation.
