Work Up

We describe a case of severe headaches, double vision, and progressive vision loss secondary to a ruptured intracranial cyst (IAC) in a 31-year-old woman with no relevant past medical history. The case is peculiar because drainage of the subdural hygroma led to a minimal improvement in vision with persistent elevated intracranial pressure (ICP). Further exploration revealed transverse sinus stenosis necessitating stenting. Evaluation post-stenting showed marked reduction of ICP and improvement in symptoms. This report underscores the importance of comprehensive work-up and suspicion of multiple underlying etiologies that may be crucial to complete resolution of presenting symptoms in some cases. We provide an overview of the clinical indications and evidence for venous sinus stenting in treating idiopathic intracranial hypertension (IIH).

Introduction : Although venous sinus stenting is an established treatment for medically refractory idiopathic intracranial hypertension, a subset of patients shows little or no improvement of symptoms after stenting. While this could be related to a number of factors, failure to sufficiently address the pressure gradient is one that can be recognized during the treatment procedure. We describe two patients who had a persistent venous pressure gradient after stent placement. Once identified, a second stent was placed with subsequent resolution of the pressure gradient. Methods : This retrospective chart review identified patients at a single institution who underwent venous sinus stenting and required immediate placement of a second venous sinus stent for a persistent pressure gradient. Results : Two patients with refractory idiopathic intracranial hypertension underwent cerebral angiography with venous manometry. In the first patient, unilateral venous sinus stenosis was present with a maximum pressure of 50 mmHg, which only decreased to 30 mmHg after placement of a right transverse‐sigmoid sinus stent. Subsequent manometry revealed a persistent gradient between the superior sagittal sinus and the right transverse sinus, which resolved after placement of a second stent in this location. In the second patient, bilateral stenosis was observed at the transverse‐sigmoid sinus junction; the maximum venous pressure was 40 mmHg, and a gradient of 30 mmHg was measured at the right transverse‐sigmoid junction, where a venous sinus stent was placed. Venous sinus pressure measurements performed immediately after the stent placement demonstrated a persistent pressure gradient of 20 mmHg in the contralateral transverse‐sigmoid sinus junction, which resolved after contralateral stent placement. Both patients showed sustained improvement in their symptoms at 1 year follow up. Conclusions : In some patients with idiopathic intracranial hypertension and venous sinus stenosis, a single stent may not sufficiently reduce the pressure gradient. A second stent may be required; however, this is only detectable with post‐stent pressure measurements. Performing manometry after stent placement should be routinely performed in order to detect persistent venous pressure gradient.

BackgroundVenous sinus stenting is an effective treatment for patients with idiopathic intracranial hypertension (IIH) and venous sinus stenosis.ObjectiveTo determine the usefulness of venous sinus stenting in the treatment of patients with symptomatic venous sinus stenosis without a diagnosis of IIH.MethodsWe performed a retrospective review of a prospective multicenter database of patients undergoing venous sinus stenting between January 2008 and February 2016. Patients with acute dural venous sinus thrombosis, arteriovenous fistula or arteriovenous malformation, or IIH were excluded. Clinical, radiological, and ophthalmological information was recorded.ResultsNine patients met the inclusion criteria and underwent venous sinus stenting for symptomatic dural venous sinus stenosis. Reasons for treatment included isolated unilateral pulsatile tinnitus (n=1), congenital hydrocephalus (n=2), unilateral pulsatile tinnitus following prior venous sinus thrombosis (n=1), acquired hydrocephalus following dural sinus thrombosis (n=2), meningitis (n=2) and tumor invasion into the dural venous sinus (n=1). Six patients underwent lumbar puncture or shunt tap, and all of these patients had elevated intracranial pressure. All stenoses were located in the transverse sinus, transverse–sigmoid junction and/or jugular bulb, and all were treated with self-expanding bare-metal stents. At follow-up, clinical symptoms had resolved in all but two patients, both of whom had congenital hydrocephalus and pre-existing shunts. There was no significant in-stent stenosis, and patients with ophthalmological follow-up demonstrated improvement of papilledema.ConclusionsDural venous sinus stenting may be an effective treatment for patients with symptomatic venous sinus stenosis without IIH in carefully selected cases, but may not be effective in resolving the symptoms of congenital hydrocephalus.

BackgroundDural venous sinus stenting has emerged as an effective and durable treatment for idiopathic intracranial hypertension (IIH). Improved visualization of the venous sinuses can improve stent placement.MethodsWe present two cases of IIH treated with venous sinus stenting in which retrograde three-dimensional rotational venography (3DRV) provided superior anatomical details of the venous sinuses for optimal sizing and positioning of stent.ResultsComparison of pre-stent 3DRV with post-stent contrast-enhanced flat panel detector CT allowed confirmation of stent placement and the result of stenosis dilation.ConclusionThis 3DRV technique provides precise visualization of venous sinus stenosis prior to stenting without the need for arterial cerebral angiography during the treatment course.
