A 67-year-old patient presented with a headache, vertigo and nausea, followed by a disturbance of consciousness. CT and MRI showed venous ectasia at the left cerebellopontine angle and extensive oedema in the left cerebellum. Angiography demonstrated a dural arteriovenous fistula that appeared at the left superior petrosal sinus–cavernous sinus) junction. After the evaluation of the shunt point, occluded areas were recanalised via the femoral vein with a quadriaxial catheter system using a 6-Fr guiding sheath, 6-Fr guiding catheter, 4.2-Fr catheter and microcatheter. Selective coil embolisation was performed, resulting in shunt removal.
