Insights

Infantile dural arteriovenous fistula (iAVF) is rare. A combined endovascular and surgical approach effectively treated a recurrent case, improving epilepsy symptoms.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Pediatric Neurosurgery

Background:

  • Infantile dural arteriovenous fistula (iAVF) is a rare cerebrovascular malformation with a historically poor prognosis and low cure rates.
  • Current treatments, primarily endovascular embolization, aim for complete anatomical cure and normal patient development.

Observation:

  • A 20-month-old girl presented with epilepsy secondary to a right transverse sinus dural arteriovenous fistula.
  • Initial transvenous embolization with platinum coils provided temporary epilepsy relief but did not achieve complete shunt occlusion.

Findings:

  • Recurrence of epilepsy and increased shunt flow were observed nine months post-embolization.
  • A multimodal treatment strategy involving transarterial embolization and surgical resection of the affected sinus ultimately eliminated shunt flow and significantly improved epilepsy.

Implications:

  • Combined endovascular and surgical treatment may be a superior strategy for managing recurrent infantile dural arteriovenous fistulas.
  • This case highlights the potential for improved outcomes with aggressive, multi-modal intervention in complex pediatric cerebrovascular malformations.
