Abstract
Objective

To evaluate the characteristics of patients on whom long-term Video-EEG monitoring is performed in a specialist centre and to assess its suitability to study refractory epilepsy patients.

Methods

A prospective analysis and study of Video-EEG monitoring was performed in a series of 100 refractory epilepsy patients from a single centre. The analysis included demographic data, the time until the first seizure, the methods used to provoke seizures, and the outcome (usefulness, change in the management, pharmacological and surgical improvement). A subgroup analysis based on diagnosis was performed.

Results

The study was performed mainly on young people (mean 34.4 years) and the fi rst seizure appeared in a mean of 30 hours, requiring most of the patients to withdraw the medication. Nevertheless, there were no cases of status epilepticus. The usefulness of the test was high in all the groups. The management was changed in 65% of the patients with pharmacological and surgical improvement.

Conclusion

Long-term Video-EEG monitoring is a suitable test to study refractory epilepsy patients. The main problem in our country is accesibility

Resumen
Objetivo

Evaluar el patrón de pacientes a los que se realiza monitorización prolongada Video-EEG en un centro especializado en epilepsia y valorar la utilidad de dicha técnica en la epilepsia farmacorresistente.

Métodos

Se realizó el estudio y análisis prospectivo de la monitorización de 100 pacientes consecutivos con epilepsia farmacorresistente correspondientes a un solo centro. Se analizaron los datos demográfi cos de la serie, el tiempo trascurrido hasta la primera crisis, las maniobras de provocación de crisis y el rendimiento de la prueba (utilidad del test, cambio de actitud, mejoría en el ajuste farmacológico y mejoría quirúrgica). Se realizó un subanálisis en diferentes grupos diagnósticos.

Resultados

El estudio se realizó fundamentalmente en población joven (34,4 años) y la media de horas trascurridas hasta la primera crisis fue de 30, requiriendo en la mayoría de pacientes (90%) retirar la medicación antiepiléptica. Pese a ello, no se produjo ningún caso de status epiléptico. La utilidad del test fue elevada en todos los grupos permitiendo cambiar el manejo de los pacientes en un 65%, lo cual se tradujo en mejorías tanto a nivel farmacológico como quirúrgico.

Conclusión

La monitorización prolongada Video-EEG es una técnica adecuada para el estudio de pacientes con una epilepsia farmacorresistente, siendo el mayor problema en nuestro medio su difícil accesibilidad.
