Resumen

La introducción del control neuroflsiológico intraoperatorio ha conseguido minimizar el riesgo funcional quirúrgico en lesiones localizadas en áreas cerebrales funcionales. En la actualidad realizamos control neuroñsiológico intraoperatorio para localizar el área motora o sensitiva y el área del lenguaje mediante estimulación cortical, así como de los pares craneales en cirugía del ángulo ponto cerebeloso. La monitorización neuroñsiológica durante cirugía del tronco del encéfalo y fosa romboidea está menos instaurada.

La cirugía del tronco del encéfalo implica una cuidadosa selección de los pacientes, dado el alto riesgo de morbilidad y mortalidad asociadas. Por esta razón, los cavernomas de esta región suelen ser tratados de manera conservadora cuando se trata de un hallazgo casual o no son sintomáticos. Sin embargo, la presencia de un sangrado o afectación neurológica inducen a tomar una decisión quirúrgica, dada la mala evolución natural.

Presentamos el caso de una mujer de 29 años, diagnosticada de cavernomas múltiples, que ingresó por cuadro de debilidad motora y déficit sensitivo en hemicuerpo izquierdo. Se realizó TC craneal y RM que mostraba hemorragia protuberancial y se practicó una craniectomía infratentorial y resección de la lesión vascular por línea media, con control neurofisiológico intraoperatorio del VII, VIII, X y XII pares craneales con lectura electromiográfica.

El control neurofisiológico ayudó a decidir el punto de acceso a la lesión que no afloraba a la superficie, minimizar las secuelas postoperatorias y pronosticar precozmente los déficits asociados con el fin de iniciar una rehabilitación precoz.

Summary

Neurophysiological monitoring during surgery to avoid damaging of eloquent brain áreas is a useful tool. We are performing intraoperative neurophysiological test to lócate motor, sensitive and speech áreas with cortical stimulation and cranial nerves during cerebellopontine cranial base surgery. Neurophysiological monitoring during brain stem surgery has been less described.

Brain stem surgery implies a careful selección of patients for surgery given the high risk of morbidity and mortality. For this reason, conservative treatment is usually indicated when an asymptomatic cavernoma is incidentally found. Instead, when bleeding or neurological deficit appear, operative treatment may be indicated and then the goal of surgery is to avoid the disability linked to the natural history.

We present the case of a 29 years oíd woman with diagnosis of múltiple cavernomas. She was admitted at our hospital because she presented weakness and sensitive disturbance of left limbs and dizziness. The CT sean and MRI showed a pontine haemorrhage caused by a cavernous hemangioma. We operated her on using neurophysiological monitoring of VII, VIII, X and XII cranial nerves with electromyographic recordings.

Postoperative disability could be reduced with a better knowledge of entry zone into the brain stem and early physiotherapy.
