Spinal arteriovenous malformations are rare diseases with a low prevalence and a complex diagnosis that usually requires the several neuroscience disciplines collaboration. Multidisciplinary approach requires fluid communication, favorable work environment and a correct social relationship, thus avoiding the conflict of interest appearance. We reported a 31 years old female referred to our department with progressive asymmetric spastic paraparesia for 10 months of evolution and occasional bladder dysfunction. With the diagnosis of a type IV arteriovenous malformation, a scheduled embolization was performed resulting in a massive subarachnoid hemorrhage due to the ASA laceration requiring an emergency bifrontal craniectomy. We discuss the neurosurgeońs role in complications during endovascular spinal vascular pathology treatment.
