Segmental upper mid-basilar artery sacrifice in a child using a Micro Vascular Plug device for treatment of a basilar arteriovenous fistula compressing the brainstem

Summary

This case demonstrates a rare pathology of basilar artery pial arteriovenous shunting presenting with acutely progressive symptoms of brainstem compression, in which we applied a polytetrafluoroethylene-coated embolic device to achieve short-segment upper mid-basilar artery sacrifice. In addition to presenting a rare form of basilar arteriovenous fistula (AVF) (likely related to hereditary hemorrhagic telangiectasia) and discussing the extreme management challenges, this case demonstrates the unusual but successful application of a novel neurovascular device. Unanswered questions include the mechanism of development of this pathology and the optimum post-embolization anticoagulation plan.

Background

Reports of pial arteriovenous fistulas (AVFs) that occur in the posterior fossa are quite rare, occasionally appearing in general pial AVF case series or as individual case reports;1–6 in particular, direct AVFs originating off the basilar artery have not previously been reported. We present...
