Occurrence of Metachronous Intracranial Dural Arteriovenous Fistula after Embolization of Intracranial Dural Arteriovenous Fistula: A Case Report.

Intracranial dural arteriovenous fistula (DAVF) is an abnormal arteriovenous shunt accounting for approximately 10%-15% of all intracranial vascular malformations. Most intracranial DAVFs are solitary, but multiple lesions at different sites can rarely occur. Most intracranial multiple DAVFs are synchronous types, whereas metachronous lesions are relatively uncommon. Herein, we report a rare case of metachronous DAVF occurring after the embolization of a preceding lesion in a 75-year-old female.
