Estimulación de nervio vago en epilepsia refractaria y callosotomía previa sin mejoría. Reporte de caso

Abstract

Refractory epilepsy is a pathology that occurs in up to 40% of patients diagnosed with epilepsy worldwide. In this context, it should be mentioned that many of these patients are underdiagnosed and incorrectly treated, worsening their clinical picture in the long term. The failure of antiepileptic pharmacological treatment leads to the implementation of surgical methods as palliative treatments for this disease, among the main method is callosotomy as the first line and if it fails, there are other alternatives such as left vagus nerve stimulation and stimulations transcranial. We present the case of a 24-year-old male patient with a pathological history of generalized tonic-clonic seizures confirmed by a 24-hour video electroencephalogram, predominantly nocturnal for 13 years, undergoing 2 different antiepileptic drug regimens over a period of 7 years in duration, later diagnosed with refractory epilepsy, for which callosotomy was performed without control of its clinical picture, the same year vagus nerve stimulation was performed, presenting favorable results in its evolution.
