Dural arteriovenous shunt involving the superior petrosal sinus: presentation and treatment by transvenous embolisation via the occipital and transverse sinuses

Abstract

We report a dural arteriovenous shunt on the superior petrosal sinus at the origin of the petrosal vein, and its treatment. This is the first report of transvenous embolisation of such a shunt through the contralateral occipital and transverse sinuses. It was possible to achieve complete obliteration of the superior petrosal sinus shunt by coils and polyvinyl acetate liquid embolisation, in a combined venous and arterial approach.
