    In their article, Hendriks et al 1 present 20 isolated sinus dural arteriovenous fistulas (DAVFs) with multimodal approaches to achieve the complete occlusion of the fistulas. Transarterial embolization (TAE) with Onyx had a success rate of 66.7% and transvenous embolization (TVE) a success rate of 77.8%. All three open TVEs and one surgery resulted in complete closure of the fistulas. A middle meningeal artery rupture occurred during TAE, and a cerebellar hematoma occurred during TVE, necessitating craniectomy. Complete occlusion rate of the fistulas was 100% when followed up. The authors did not specify the recurrence rate of DAVFs in the article. Because digital subtraction angiography is the gold standard, we believe that some patients had a follow-up magnetic resonance angiography scan, which might overestimate the total complete occlusion and understate the recurrence …
