Utility of CT venography in monitoring stent patency in idiopathic intracranial hypertension: retrospective single-center study.

Background: Cerebral venous sinus stenting is an established treatment for patients with idiopathic intracranial hypertension (IIH), refractory to medical management and with stenotic venous sinus on conventional cerebral venography. Currently, there are no clear guidelines on optimal noninvasive imaging modality for routine post-stenting follow-up. We investigated diagnostic yield of CT venography (CTV) for evaluation of stent patency.

Reductions in bilateral transverse sinus pressure gradients with unilateral transverse venous sinus stenting for idiopathic intracranial hypertension.

Background: Venous sinus stenting is an effective treatment for papilledema associated with idiopathic intracranial hypertension (IIH). It is unclear whether unilateral transverse-sigmoid sinus (TSS) stenting adequately decompresses the contralateral TSS system in cases of bilateral transverse sinus stenosis. The objective of this study was to compare changes in bilateral TSS pressure gradients following unilateral TSS stenting in a series of patients with IIH.
