Abstract

The objective of the study was to evaluate imaging and clinical results of endovascular intervention of cavernous sinus dural arteriovenous fistula (CSDAVF) in 2 men and 13 women with an average age of 58,67±14.93, at Saint Paul General Hospital from June 2018 to March 2021. The results according to the Barrow classification are as follows: type D (8; 53.3%), type C (3; 20%), type C and D (2; 13.3%) and type A and B (1; 6.7%). Among of the 23 access approaches to embolization, there were 12 cases of crossing the inferior petrosal sinus, 5 cases through the facial vein, 4 cases via artery, 2 cases of direct puncture access to the superior ophthalmic vein. Complete fistula occlusion had 13 patients (86.7%) and all of them were occluded cavernous sinus by coils. One patient had incomplete occlusion (90%) and the symptoms were significantly relieved after 13 months. Another patient had a type D fistula through the small branch of the ophthalmic artery that was inaccessible, but chemosis was very mild and had not progressed after 15 months. Thus, endovascular intervention is a highly effective and safe method in the treatment of CSDAVF.
