Transvenous Embolization for Vertebral Arteriovenous Fistula: Report of two Cases and Technical Notes

摘要

Background. Vertebral arteriovenous fistulas are relatively rare. Although the common treatment is transarterial embolization, it may be impossible to pass through the fistula (e.g. a microfistula created by a needle puncture). We report two patients with vertebral arteriovenous fistulas due to penetrating trauma who were successfully treated by transvenous embolization.
