| Popis: | Vagus nerve stimulation (VNS) has been approved for the treatment of refractory epilepsy when resective surgery is not possible, and has proved to be highly effective. Series published in the literature suggest a beneficial effect of VNS in the treatment of migraine.To determine the degree to which headaches improve in patients with migraine after the placement of VNS to treat refractory epilepsy, and to evaluate what variables are associated with an increased chance of success with this measure.An observation-based retrospective study was conducted from 1st January 1999 until 31st December 2010. Patients with VNS for refractory epilepsy were contacted by telephone, after selecting those who fulfilled International Headache Society criteria for migraine. Data collected included age, gender, year of placement, age at onset of epilepsy and migraine, improvement of seizures and migraine, presence of migraine with aura and coexistence of anxious-depressive syndrome. Ninety-four patients with VNS were contacted and 13 patients with migraine were selected.Following placement of the VNS, the number of episodes of migraine was seen to decrease by at least 50% in nine patients (69%) (p = 0.004) and there was a drop in the number of episodes of migraine in those patients who had also reduced their epileptic seizures (p = 0.012). No statistically significant associations were observed as regards sex, age, length of disease history, existence of migraine with aura or coexistence of anxious-depressive syndrome.VNS could have beneficial effects for patients with migraine, especially in cases that are difficult to control. Due to the type of study, these conclusions must be taken with caution. Prospective clinical studies are needed before introducing the technique into daily clinical practice.Estimulacion del nervio vago en pacientes migrañosos.Introduccion. La estimulacion del nervio vago (ENV) esta aprobada para el tratamiento de la epilepsia refractaria cuando no es posible cirugia resectiva, con una eficacia bien establecida. Series publicadas sugieren un efecto beneficioso de la ENV en la migraña. Objetivos. Determinar el grado de mejoria de la cefalea en pacientes migrañosos a los que se les habia implantado una ENV para tratamiento de la epilepsia refractaria y evaluar que variables se asocian a mayor posibilidad de exito con esta medida. Pacientes y metodos. Estudio observacional y retrospectivo desde el 1 de enero de 1999 hasta el 31 de diciembre de 2010. Se contacto telefonicamente con los pacientes con ENV para epilepsia refractaria, seleccionando a aquellos que cumplian los criterios de la Sociedad Internacional de Cefaleas para la migraña. Se recogieron edad, genero, año de implantacion, edad de inicio de la epilepsia y la migraña, mejoria de crisis y de migraña, presencia de aura migrañosa y coexistencia de sindrome ansiosodepresivo. Se contacto con 94 pacientes con ENV y se selecciono a 13 pacientes migrañosos. Resultados. Tras la implantacion de la ENV, se observo una disminucion de al menos el 50% de los episodios de migraña en nueve pacientes (69%) (p = 0,004), asi como una disminucion del numero de episodios de migraña en aquellos pacientes que tambien habian reducido sus crisis epilepticas (p = 0,012). No se observaron asociaciones estadisticamente significativas en cuanto al sexo, edad, tiempo de evolucion, existencia de aura migrañosa o coexistencia de sindrome ansiosodepresivo. Conclusiones. La ENV podria resultar beneficiosa en pacientes con migraña, especialmente en casos de dificil control. Debido al tipo estudio, hay que tomar estas conclusiones con precaucion. Seran necesarios estudios clinicos prospectivos antes de llevarse a la practica clinica habitual. |
