    Craniocervical junction arteriovenous fistulas (AVFs) are rare vascular malformations, comprising only 1–2% of cranial or spinal AVFs.

  • 2

    Common manifestations of CCJ AVFs include subarachnoid hemorrhage and venous hypertensive myelopathy, with hemorrhagic cases linked to specific drainage patterns.

  • 3

    Microsurgery is the primary treatment for CCJ AVFs, offering high obliteration rates, while endovascular treatment is limited to select cases.

  • 4

    Prognosis for CCJ AVFs varies based on presentation, lesion subtype, venous drainage pattern, and treatment-related complications.

  • 5

    Structured angiographic follow-up is essential after treatment of CCJ AVFs to monitor for complications and recurrence.
