Abstract

Aims: To report the endovascular treatment and complications of intracranial and spinal dural arteriovenous (AV) fistulas.

Methods: A retrospective analysis of 863 cases with dural AV fistulas was completed in the nationwide registry study of the Japanese Society of Neuroendovascular Therapy.

Results: Treatments included transarterial/transvenous embolization (TAE/TVE), open surgery, stereotactic radiation, and their combinations. Modified Rankin Scale 0 (mRS-0) of the patients before and after treatment were 21% and 68%, and mRS 0-1were 69% and 86%, respectively. Mortality rate after treatment was 0.6%. Major complications of TAE and TVE were cranial nerve palsy and cerebral infarction.

Conclusions: Major complications resulted from occlusion of vasa nervosum and material migration via dangerous intracranial and extracranial arterial anastomosis.
