Аннотация
BACKGROUND: Intracranial pial arteriovenous fistulas (pAVFs) are rare vascular lesions, which may present with, but are distinct from arteriovenous malformation and dural arteriovenous fistula. They most often manifest during infancy or early childhood, but rarely in adulthood.
METHODS: We report an exceptionally rare case of infratentorial pAVF in a 73-year-old man, who presented with progressive gait disturbance due to cerebellar edema resulting from arteriovenous shunts.
RESULTS: The patient was successfully treated by endovascular flow reduction followed by surgical extirpation of the fistula. The diagnosis was confirmed by pathological findings.
CONCLUSIONS: Pial arteriovenous fistula is rare, but can occur in the elderly. Combination of endovascular flow reduction and surgical disconnection yielded an excellent clinical outcome.
