Fístula arteriovenosa dural, lesión medular y disinergia vesicoesfinteriana

ResumenLa fístula arteriovenosa dural es una patología infrecuente con repercusión neurológica cuya sospecha clínica es importante ya que su pronóstico depende de la rapidez con la que se instaure el tratamiento.AbstractDural arteriovenous fistula is a rare pathology with neurologic repercussions. Its clinical suspicion is important, given that its outcome depends upon the speed with which treatment is established. Not a congenital vascular malformation, but rather of acquired etiology, the fistula is made up of a ball of small arterial vessels located in the thickness of the dura mater of the dural sac.A 22-year-old man with an unremarkable past history came to the emergency service complaining of paresthesia in the left lower limb after a slight trauma 10 days before. Symptoms worsened after one month and a lumbar nuclear magnetic resonance scan revealed a high-flow paravertebral arteriovenous fistula with a trajectory and inclusion within the lumbar canal from L1 to L3
