Insights
Surgical removal of cerebral cavernous angiomas (also known as cavernomas) effectively treats epilepsy in children. This procedure led to significant seizure reduction or complete seizure freedom in all patients, preventing further neurological complications.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Vascular Malformations
Background:
- Epilepsy is a common symptom of cerebral cavernous angiomas (cavernomas).
- Surgical resection is the preferred treatment for intractable or long-standing seizures caused by cavernomas, especially in patients with poor medical compliance.
Purpose of the Study:
- To report the outcomes of surgical treatment for epilepsy in children with cerebral cavernomas.
- To evaluate the efficacy and safety of surgical cavernoma removal in pediatric patients.
Main Methods:
- Retrospective analysis of 11 pediatric patients with epilepsy due to cerebral cavernomas.
- Surgical removal of cavernomas, with stereotactic localization used in 3 cases for deep-seated lesions.
- Follow-up ranging from 1 to 16 years.
Main Results:
- All 11 patients experienced improved seizure control post-surgery.
- Eight patients (72%) became seizure-free on their preoperative medication.
- One patient achieved seizure freedom with reduced medication, and two (18%) became seizure-free without medication.
Conclusions:
- Surgical removal of cerebral cavernomas is a safe and effective treatment for pediatric epilepsy.
- The procedure eliminates the risk of hemorrhage and further neurological deficits associated with cavernomas.
- Complete resection prevents the spread and autonomization of the epileptogenic zone induced by the cavernoma.
Abstract:
Epilepsy is the most frequent presenting symptom of cerebral cavernous angiomas or cavernomas, and surgical removal of these vascular malformations is considered the treatment of choice in patients with intractable or long-standing seizures, or in those with poor compliance to medical therapy. In this paper the results of surgical treatment in 11 children with seizures from cerebral cavernomas are reported. Surgery for deep-seated cavernomas was aided in 3 cases by a stereotactic localization technique, that allowed a limited approach with minimal brain damage. Major morbidity and mortality were absent; follow-up ranged between 1 to 16 years. Improved seizure control was seen in all the patients: eight (72%) became seizure-free with the same preoperative therapy; one became seizure-free with a lower drug dosage, and two (18%) were seizure-free without medical therapy. The removal of cavernomas prevented the risk of haemorrhages or further deficits from growth and, above all, avoided spreading and autonomization of the epileptogenic area induced by the cavernoma.
