A case of high-flow dural AVF involving the left lateral sinus

The patient had severe tinnitus and there was sinus reflux. The challenge in these cases is to get the common venous channel completely in the first attempt. Occluding arterial network is futile and leads to recurrence; further treatment can be challenging. In this case, there was no good arterial access. We decided to go with a transvenous approach. Multiple venous channels were merging into one, which in turn drained into the sigmoid sinus. So, we selectively placed three microcatheters into these three draining channels in a retrograde manner. We inflated an RC balloon to control the permeation of the onyx and to maintain the patency of the sinus. Although, it may look technically elaborate, to us this gave us a strategy to achieve an almost complete occlusion when there are no good arterial feeders. A small dural AVF was noted in another part of the sinus with no sinus reflux. #DuralAVF #EndovascularTreatment #OnyxEmbolization #TransvenousApproach #AVFTreatment #TinnitusRelief #SinusReflux #StrokeCare #AdvancedNeuroCare #MinimalIyinvasive #parasneuro #parashealth
