Focus of the Report: This report focuses on venous sinus stenting (VSS) for treatment of idiopathic intracranial hypertension (IIH) that has failed to respond to available drug and conservative treatments.
Technology Description: VSS is an endovascular procedure performed via the jugular veins that involves placement of 1 or more stents in a cerebral vein, such as the transverse sinus, with or without balloon angioplasty, with the patient under general anesthesia.
Controversy: Venous sinus stenosis seems to be a secondary effect rather than a cause of idiopathic intracranial hypertension; therefore, VSS therapy may not provide complete relief of symptoms.
Key Questions:
Does VSS improve outcomes in patients with IIH?
How does VSS compare with established methods for treatment of IIH?
Does VSS pose any safety issues?
Have definitive patient selection criteria been established for use of VSS in patients with IIH?
