Abstract
Purpose: To evaluate the apply the transvenous balloon protection in endovascular intervention of non - cavernous sinus dural arteriovenous fistula.
Material and methods: The uncontrolled interventional study was conducted in Radiology center at Bach Mai hospital from January 2017 to August 2020. 15 patients with non - cavernous sinus dural arteriovenous fistula underwent endovascular treatment using transvenous balloon protection.
Results: 15 patients were treated in 18 procedures. Among these, there were 7 males and 8 females, mean age was 48.2 ± 14.82 years. Most non - cavernous sinus dural arteriovenous fistulas were located at the transverse - sigmoid sinus (76,5%). According to the Cognard classification, Cognard IIa accounted for 47%, Cognard IIb accounted for 17,6%, Cognard IIa+b
accounted for 29,4%, and Cognard IV accounted for 5,9%. Most fistulas presented with multiple feeding arteries, the most common artery was middle meningeal artery. With 18 procedures underwent tranvenous balloon protection, the sinus protection was achieved in 17 out of 18 patients. 86,7% of these patients had complete occlusion of fistula, whereas partial occlusion occurred in 13,3% of these patients. After treatment, 86,7% of these cases didn’t have complication, complete symptom remission rate was 53,3%,26,7% showed symptom relief. Only 1 case had severe complication, accounted for 5,6%.
Conclusion: Endovascular intervention using transvenous balloon protection is a safe and effective technique in the treament of non - cavernous sinus dural arteriovenous fistula.
