Introducción: las fístulas arteriovenosas intradurales dorsales espinales (FAVIDE) son lesiones poco frecuentes y complejas que son subdiagnósticadas y condicionan discapacidad. El objetivo es presentar nuestra experiencia en el manejo endovascular.
Métodos: estudio ambispectivo de pacientes con FAVIDE, tratados mediante terapia endovascular (TEV) con n-butil-cianoacrilato en el periodo de 2007 a 2013.
Resultados: se incluyeron 15 pacientes con edad media de 37 años. En 12 casos la presentación fue progresiva e insidiosa en un lapso de entre 6 meses y un año, mientras que 3 presentaron hemorragia. La lesión tuvo localización torácica en 73 % de los casos, lumbar en 20 % y cervical en 7 %. Previo al tratamiento observamos discapacidad de grados 5 y 4 en 73 %, y 67 % tenían alteraciones de la micción de grado 3. Como complicaciones, solo una paciente tuvo deterioro del estado de alerta transitorio 6 horas después del procedimiento. Se encontró una mejoría hacia los grados 1 y 2 de discapacidad, a las 48 horas, 3 y 6 meses, de 53 %, 73 % y 87 %, respectivamente.
Conclusiones: con la TEV se tiene un tiempo quirúrgico corto, el volumen de hemorragia es bajo y la estancia hospitalaria es corta, respecto de otras técnicas quirúrgicas. La TEV es un procedimiento seguro y con efectividad significativa en el tratamiento de FAVIDE. Esta es la primera serie de casos tratados con TEV en México.
