  • Title: Microcatheter pull-up technique in the transvenous embolization of an isolated sinus dural arteriovenous fistula. Technical note.
    Author: Hanaoka M, Satoh K, Satomi J, Matsubara S, Nagahiro S, Takimoto O, Ohbayashi M.
    Journal: J Neurosurg; 2006 Jun; 104(6):974-7. PubMed ID: 16776344.
    Abstract:
    The authors describe a novel technique involving the use of a gooseneck snare for microcatheterization of isolated sinus dural arteriovenous fistulas (DAVFs). In some patients the inferior petrosal and transverse-sigmoid sinuses, the route of transvenous embolization (TVE) for DAVF, are separated by several channels. Even if a guidewire can be passed over the occluded portion and the affected sinus can be accessed, one may not necessarily be able to insert a microcatheter. The authors report on three patients who underwent successful microcatheterization via a novel pull-up technique, which makes use of a gooseneck snare to perform TVE even in very difficult circumstances.
