Treatment of dural arteriovenous fistula involving the transverse-sigmoid region with cortical reflux is complex and treatment options may require sacrifice of the fistulous segment of the sinus. ⋯ Fistulas of the transverse-sigmoid sinuses with cortical reflux may require sacrifice of the parent sinus for cure.
