Cerebral venous sinus stenting in idiopathic intracranial hypertension
Cerebral venous sinus stenting (CVSS) is a minimally invasive procedure using endovascular stent placement to relieve elevated intracranial pressure secondary to venous sinus stenosis. Increased venous sinus pressure secondary to stenosis is commonly associated with elevated intracranial pressure without intracranial lesions on imaging or idiopathic intracranial hypertension (IIH). While the etiology of IIH remains unknown, stenosis of one or more of the dural sinuses has been implicated as a possible underlying mechanism. The manifestations of IIH include headaches, transient vision loss, pulsatile tinnitus, and neck pain. In this review, we discuss the recent studies that have demonstrated the effectiveness of CVSS for patients with IIH and also the indications, technical challenges, potential complications, and emerging developments in CVSS.
