Endovascular management of type III perimedullary spinal arteriovenous malformations in pediatric population

Background: Spinal arteriovenous malformations (AVMs) are a cause of 20-30 of all spinal vascular malformation. The treatment option for the AVM depends upon the type of AVM. Here, we present a case series to discuss the type, management, and post-operative conclusion of the spinal AVMs. Method: Four patients with spinal AVMs were retrospectively reviewed. All 4 patients were with a nidus-type AVM. Treatment for all patients required embolization. Clinical features, imaging, treatment, and clinical results were observed. All 4 patient's clinical outcome was assessed using the Modified Ranked Scale. Result: The follow-up after management showed that all four-patient recovered without any residual deficit. All four-patient scored zero (0) on the Modified Ranked Scale. Conclusion: Pediatric spinal AVMs are rare and require complex multimodal approach to achieve favorable outcomes.
