Abstract

Objective: Evaluate the results of treatment of indirect cavernous sinus dural arteriovenous fistula by endovascular intervention. Methods: Cross-sectional study on 54 cases of indirect cavernous sinus dural arteriovenous fistula (iCS-DAVF) treated with endovascular intervention at University Medical Center from October 2018 to April 2020. Results: Mean age was 53.7 ± 15.6 years. Red eyes symptoms account for a high rate: 44 cases (81.48%), 23 bulging eyes (42.6%), 23 cases with reduced vision (42.6%). The most common type of fistula in this study is iCS-DAVF type D (accounting for 77.8%) according to the Barrow classification, Type IIa according to the Cognard classification (accounting for 44.4%). Interventional access from veins: inferior petrosal sinus accounts for 77.77%, ophthalmic vein accounts for 5.55%. There is no correlation between the approach and the results immediately after intervention with p> 0.05. Clogging material coils was used in 47 patients (81.5%), glue liquid - Onyx – coils in 6 patients (7.4%), and ballon in only 1patient (1.9%). Complete leak rate is 81.5%, nearly complete is 18.5%. Deaths rate is 0%. Conclusion: Endovascular intervention is an effective treatment method for iCS-DAVF, which should be applied at facilities with adequate diagnostic equipment and experienced vascular intervention teams.
