A Case of Dural Arteriovenous Fistula in the Falx with Prominent Falcine Venous Plexus

抄録

Objective: The falx cerebri is known to have venous plexuses. Although some cases of dural arteriovenous fistula (DAVF) associated with falcine sinus have been reported, DAVF in the falx with prominent falcine venous plexus has not previously been reported.

Case Presentation: A 59-year-old male was hospitalized with head trauma. MRI incidentally showed a possible occipital DAVF. CTA and DSA revealed a DAVF in the flax with prominent falcine venous plexus. We performed a selective transarterial embolization with glue and particle, obtaining a complete occlusion of the fistula.

Conclusion: We report a rare case of DAVF in the flax with prominent falcine venous plexus that was successfully treated by a transarterial embolization.
