Venous Sinus Stenting for Idiopathic Intracranial Hypertension

This study adds to growing case-series evidence that venous sinus stenting effectively treats medically refractory IIH.

Mounting evidence has demonstrated the presence of venous sinus stenosis in patients with idiopathic intracranial hypertension (IIH). These authors report findings from a single-center case series of 10 consecutive patients who underwent venous sinus stenting for IIH that was refractory to medical treatment. All 10 patients had a stenosis at the typical location, the junction of the transverse and sigmoid sinuses, visualized by three-dimensional rotational gadolinium-enhanced magnetic resonance angiography and confirmed by direct retrograde cerebral venography. Eight patients had impaired visual acuity. The mean prestenting pressure gradient across the stenoses was 19.1 mm Hg.

At 3 months after venous sinus stenting, all 10 patients showed n…
