OBJECTIVE We retrospectively searched for cases of transvenous embolisation for cavernous sinus dural arteriovenous fistulas. METHODS Twenty-five cases underwent transvenous embolisation via the inferior petrosal sinus (IPS). IPS was probed using a standard 0.035-inch guidewire for microcatheter navigation, which was successful in all cases. RESULTS IPS was occluded in 17 cases (68%). Only one case experienced a complication, where the approach was changed to the contralateral side because of internal jugular vein injury. The relationship between the external auditory canal and the IPS route was reviewed in 18 cases using digital angiography (lateral view). The guidewire passed across, above, or below the external auditory canal in 10 (56%), six (33%), and two (11%) cases, respectively. CONCLUSIONS No previous reports have analysed the relationship between the external auditory canal and the IPS route. We present a safe and successful technique for approaching the cavernous sinus via the IPS.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
