Ophthalmic vein compression for selected benign low-flow cavernous sinus dural arteriovenous fistulas.

Dural arteriovenous fistulas (DAVFs) of the cavernous sinus are acquired arteriovenous shunts between the dural branches of the internal and external carotid arteries and the cavernous sinus. These fistulas may present with cortical venous reflux, but more commonly drain antegradely toward the superior ophthalmic vein (SOV). Transvenous embolization is the most common endovascular treatment, but in some cases transvenous access to the compartment of the shunt may not be possible. In cases with no corticovenous reflux, manual compression of the SOV is an excellent alternative treatment, which is well known but rarely reported in the literature. The authors describe a series of 3 cavernous DAVFs with anterior drainage treated successfully by intermittent manual compression of the SOV.
