Technique: After informed consent and under sterile technique, the right CFA was accessed using a 6Fr sheath, and selective injections were made into the common carotid and vertebral arteries bilaterally.
Findings: The tumour is markedly hypervascular, with rapid arteriovenous shunting, with supply from inferior hemispheric branches of the large right PICA. No significant supply was identified from the left PICA. Draining veins correlate with those demonstrated on the stereotactic post contrast MRI. No other significant supply. No significant stenoses, fibromuscular disease, or intracranial aneurysms. No other hypervascular tumour is identified.
Embolisation: A 5Fr guiding catheter was placed in the right vertebral artery, a SL 10 microcatheter navigated over a Synchro soft microwire into the super selective branch directly supplying the tumour. 250-350 \XB5\ PVA prolonged injection with almost complete obliteration of the hypervascular stain, with preservation of the major branches of PICA. The procedure was uncomplicated, no new symptoms or signs developed.
Final angiographic runs demonstrate complete obliteration of the tumour stain, with the exception of a small amount seen inferiorly, with no persistent arteriovenous shunting.
