Cerebral Angiogram & AVM embolisation:
The AVM characterised previously, receives supply predominantly from PICA AICA SCA, with a compact nidus, and rapid arteriovenous shunting with drainage to the superior surface veins both medial and lateral. A 6Fr guiding catheter was placed in the LVA, an Apollo microcatheter navigated over a hybrid microwire into the medial PICA feeder at the nidus.
Onyx 18 injection with arterial, nidus, fistula obliteration complete.
Final angiographic runs demonstrate complete obliteration of the nidus, with no arteriovenous shunting, but some stasis in adjacent vessels.
