Transfemoral, Transvenous Embolisation of Dural Arteriovenous Fistula Involving the Isolated Transverse-Sigmoid Sinus from the Contralateral Side

摘要

Background: A dural arteriovenous fistula (AVF) involving the transverse-sigmoid (T-S) sinus which is occluded at its proximal and distal ends i.e., an isolated sinus, runs the risk of haemorrhaging or causing serious neurological deficits as a result of its retrograde leptomeningeal venous drainage. While lesions of this type have not been considered to be treatable by percutaneous, transvenous embolisation, this paper challenges this view.
