Incidence and Prevalence
- Rare: DAVF in children are rare. They represent up to 10% of all intracranial AV shunts in children. Only about 60 cases have been described in the literature(1).
Age Distribution
- None: There is no age predilection.
Sex Predilection
- None: There is no sex predilection.
Geographic distribution
- None: There is no geographic distribution.
Risk Factors
- Hypercoagulable states and sinus thrombosis: These should be systematically ruled out.
- Previous surgery: In very rare occasions, surgical trauma to the meninges can induce the formation of DAVFs.
- Previous trauma: In very rare occasions, head trauma can induce the formation of DAVFs.
Relationships to Other Disease States and Syndromes
- DAVFs associated with genetically confirmed vascular anomaly syndromes: Walcott et al reported the association of two cases of dAVMs with PHACE and PTEN or Bannayan-Riley-Ruvalcaba syndromes(31).
