Embolization of a Non-Galenic Pial Arteriovenous Fistula with Assistance of a SolitaireTM Stent: Case Report.

ABSTRACT

This study aimed to describe a novel endovascular strategy to help control blood flow used successfully to treat an infant with highflow pial arteriovenous fistula (AVF). Here, a single-hole high-flow nongalenic pial AVF was diagnosed in a 2.5 year-old infant is presented. After coil packing failure despite temporal balloon occlusion, we deployed a SolitaireTM stent in the fistula. By twisting with detachable coils, we achieved satisfactory blood flow control, and obliteration of the fistula was achieved with Onyx injection. In conclusion, SolitaireTM stent deployment in the high-flow pial AVF can help stabilize the coils in the fistula, leading to satisfactory blood control. This strategy may be a valuable addition to currently available options.
