Idiopathic intracranial hypertension (IIH)

• Elevated intracranial pressure (ICP) with no clear cause

• Results in stenosed venous transverse sinus (TS)

•Stenosis causes pulsatile tinnitus

Treatment – Venous Sinus Stenting (VSS)

• Performed when the intravascular pressure (IVP) gradient across the stenosis is above 8 mmHg

• 10.3% revision surgery rate

• Most common reason for revision is the occurrence of a new stenosis upstream of the stent

• There is currently no standardized criteria for the selection of stents to be used in this procedure; they are used off-label
