Transvenous microguidewire looping technique for breach of ipsilateral inferior petrosal sinus occlusions en route to cavernous sinus dural arteriovenous fistulas.

ABSTRACT:

Background and purpose

Transarterial access to dural arteriovenous fistulas (dAVFs) has been popularized by device improvements and novel embolic materials. However, this approach is limited in the cavernous sinus (CS) because of related complications and low cure rates. Although a transvenous approach, via ipsilateral inferior petrosal sinus (IPS), may be more suitable for CS-dAVFs, microcatheter delivery is occasionally impeded by ipsilateral IPS occlusion. Described herein is a microguidewire looping method to breach such occlusions, thus enabling access to CS lesions.

Methods

A microcatheter is initially advanced into the IPS orifice, and a microguidewire is passed into the occluded IPS. Looping is easily achieved through the resistance met. With greater support of the g
