Insights

Surgical resection of symptomatic cerebral cavernous malformations (CCMs) in children is effective, with over 77% becoming seizure-free post-operation. Lesion location did not significantly impact outcomes, suggesting resection is a favorable treatment option.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pediatric Neurology

Background:

  • Cerebral cavernous malformations (CCMs) are prevalent brain vascular lesions, affecting 0.5% of the population.
  • CCMs are a significant cause of brain hemorrhage in pediatric patients, presenting with seizures, headaches, and neurological deficits.
  • Surgical resection is an option for symptomatic CCMs, particularly those causing medically refractory epilepsy.

Purpose of the Study:

  • To evaluate the clinical outcomes of surgically treated pediatric patients with symptomatic CCMs.
  • To compare outcomes based on the location of CCMs in children experiencing preoperative epileptic seizures.

Main Methods:

  • Retrospective analysis of 79 pediatric patients (41 boys, 38 girls) from three centers, surgically treated for symptomatic CCMs between 1974 and 2004.
  • Mean age at first manifestation was 9.7 years; mean age at operation was 11.3 years.
  • Focus on comparing seizure outcomes (Engel Class I) relative to CCM location.

Main Results:

  • 77.3% of pediatric patients achieved seizure freedom (Engel Class I) after CCM resection.
  • No significant differences in seizure control outcomes were observed based on the location of the cerebral cavernous malformations.

Conclusions:

  • Surgical resection of symptomatic CCMs is a favorable treatment for pediatric patients, similar to adults.
  • The effectiveness of resection in achieving seizure freedom supports its consideration for symptomatic pediatric CCMs regardless of lesion location.
