Idiopathic intracranial hypertension (IIH) is a condition that causes increased pressure inside the skull also known as increased intracranial pressure (ICP). Common symptoms of IIH include headaches, visual symptoms, and pulsatile tinnitus.
The diagnostic work up may reveal swelling of the optic disc (or papilledema) on fundoscopic exam and elevated opening pressure with a spinal tap (lumbar puncture). Magnetic resonance imaging (MRI) often shows findings including a partially empty sella, optic nerve tortuosity and distention, and stenosis of the transverse venous sinus.
The neuroendovascular team can see IIH patients when venous sinus stenting is considered to treat the venous stenosis and improve all signs and symptoms of IIH.
VSS means there is narrowing of the venous sinuses, which are responsible for draining cerebrospinal fluid (CSF). When drainage is affected, the pressure in your head can increase.
IIH more commonly affects females and people with obesity.
