Venous Stenosis

Angioplasty and Stenting for Dural Venous Sinus Stenosis and Idiopathic Intracranial Hypertension / Pseudotumor Cerebri

  • Idiopathic intracranial hypertension (IIH) is also known as pseudotumor cerebri. It occurs when the pressure inside your brain (intracranial pressure) increases for no obvious reason. Patients often experience severe headaches and various visual symptoms. Some patients with IIH may have decreased blood flow through the cavities that drain blood out of the brain called dural venous sinus stenosis. Endovascular stenting of the dural venous sinus may help alleviate symptoms of IIH in some patients. Endovascular stenting of a venous sinus is a minimally invasive treatment in which a stent is placed across the area of stenosis to keep the sinus open.
