Transfrontal sinus approach for an anterior cranial fossa ethmoidal dural arteriovenous fistula

摘要

Background:Ethmoidal dural arteriovenous fistulas (eDAVFs) are usually approached via a pterional or a frontal craniotomy. A more direct route to the fistula is possible through a purely transfrontal sinus approach. The aim of this report is to illustrate the interest of transsinus frontal approach for eDAVFs.
