Usefulness of preoperative cone beam computed tomography and intraoperative digital subtraction angiography for dural arteriovenous fistula at craniocervical junction: Technical case report

Intraoperative treatment evaluation is relatively easy in embolization, whereas in direct surgery it can be difficult.
