Abstract：To investigate the safety and outcomes of transvenous embolization of bilateral cavernous sinus dural arteriovenous fistulas (CSDAVF) with Onyx and coils. Method The clinical and follow-up data of 7 patients with bilateral CSDAVF who accepted transvenous embolization with onyx and coils via inferior petrosal sinus approach from September, 2013 to September, 2018 were analyzed retrospectively. Results Of 14 CSDAVF in 7 patients with bilateral CSDAVF, 13 were totally embolized and 1 subtotally. One patient had aggravation of oculomotor paralysis and 1 patient had aggravation of abducent paralysis after the embolization. The following-up 6 months after the embolization showed that CSDAVF did not recurred in all the patients. The patient was basically recovered from oculomotor paralysis, and the another patient was slightly recovered from abducent paralysis. Conclusions The clinical effect of transvenous embolization of CSDAVF with Onyx and coils via inferior petrosal sinus approach is good, but the complications are more common after the embolization in the patients with bilateral CSDAVF than those in the patients with unilateral CSDAVF. The practised skill of endovascular emboliation is very important to successful treatment of CSDAVF and reducing complications.
