Dural sinus stenting for idiopathic intracranial hypertension: factors associated with hemodynamic failure and management with extended stenting

Some patients undergoing dural sinus stenting for idiopathic intracranial hypertension (IIH) develop clinical and hemodynamic failure (recurrence of the pressure gradient) owing to stent-adjacent stenosis.To characterize factors associated with hemodynamic failure, and to describe outcomes of patients after repeat stenting.We reviewed the initial and follow-up clinical, venographic, and hemodynamic data in 39 patients with IIH treated over 17...
