Abstract

Introduction Embolization of Dural AV fistulas with multiple feeders draining to a large venous sinus which is functional is a problem faced by Neurointerventionalists.

Aim of Study We want to describe a case of lateral dural av fistula supplied by occipital, ascending pharyngeal and vertebral artery draining to transverse sinus.

Methods A 6F guiding catheter was put in th external carotid artery ,8*80mm COPERNIC RC baloon was placed in rt transverse sigmoid sinus.Transarterial onyx embolization was done through a marathon mcrocatheter selectively placed in occipetal artery feeders. Complete embolization was done with onyx injection through a single feeder.

Results Complete cure of fistula was done using transarterial onyx embolization with preservation of transverse sinus using complaint baloon like Copernic.

Conclusion Preserving a normal drainining sinus of the brain is important to avoid venous thrombosis and venous hypertension related hemorrhagic complications in trwating a dural av fistula.
