Contralateral inferior petrosal sinus approach for transvenous embolization of a dural arteriovenous fistula at isolated jugular bulb. Technical case report.

ABSTRACT

A contralateral inferior petrosal sinus approach is described for the successful treatment of a case of a dural arteriovenous fistula at an isolated right jugular bulb presenting with chemosis. A microcatheter could be inserted into the right jugular bulb from the left jugular bulb through the left inferior petrosal sinus, basilar sinus on the dorsum sellae, and the right inferior petrosal sinus. This unusual approach represents an alternative route to the jugular bulb.
