Angioarchitecture Classification and Treatment Modalities of Craniocervical Junction Arteriovenous Fistulas: A Cohort Study of 155 Patients

CCJ AVFs can be distinguished based on the fistula location and the arterial feeders. Currently, microsurgery stands as the preferred treatment strategy for CCJ AVFs, whereas interventional embolization plays a distinctive role in cases with specific angioarchitecture or as a pretreatment measure before microsurgery.
