Introduction Dural venous sinus stenting (VSS) is an effective, durable treatment for patients with idiopathic intracranial hypertension (IIH) due to underlying venous sinus stenosis. However, the use of venous sinus stenting to treat IIH with acute vision loss has rarely been described. Methods A retrospective chart analysis identified patients who received VSS for fulminant IIH, defined as acute (< 8 weeks) visual field loss to within the central 5° and/or a decrease in visual acuity to less than or equal to 20/50 in either eye in the presence of papilledema. Results Ten patients were identified with average patient age of 31.0 years, and all except one were female. Mean body mass index was 41.2 kg/m2. All patients presented with vision loss and some with headache and tinnitus. The average trans-stenotic gradient pre-stenting was 28.7 mmHg (range 9–62 mmHg). All patients had diminished or resolved venous gradients immediately following the procedure. At mean follow-up of 60.5 weeks, 100% had improvements in papilledema, 80.0% had subjective vision improvement, 55.6% had headache improvement and 87.5% had tinnitus improvement. 90.0% had stable or improved visual acuity in both eyes with a mean post-stenting Snellen acuity of 20/30 and an average gain of 3 lines Snellen acuity post-stenting (95% confidence intervals 0.1185–0.4286, p = 0.0018). Two patients (20.0%) required further surgical treatment (cerebrospinal shunting and/or stenting) after their first stenting procedure. Conclusions This series suggests that VSS is feasible in patients presenting with IIH and acute vision loss with a fairly low complication rate and satisfactory clinical outcomes.

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).

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.

Dural Venous Sinus

Multiple pathophysiological mechanisms have been proposed for the increased intracranial pressure observed in idiopathic intracranial hypertension (IIH). The condition is well characterized, with intractable headaches, visual obscurations, and papilledema as dominant features, mainly affecting obese women. With the advent of MR venography and increased use of cerebral angiography, there has been recent emphasis on the significant number of patients with IIH found to have associated nonthrombotic dural venous sinus stenosis. This has led to a renewed interest in endovascular stenting as a treatment for IIH. However, the assumption that venous stenosis leads to a high pressure gradient that decreases CSF resorption through arachnoid villi requires further evidence. In this paper, the authors analyze the published results to date of dural venous sinus stenting in patients with IIH. They also present a case from their institution for illustration. The pathophysiological mechanism in IIH requires further elucidation, but venous sinus stenosis with subsequent intracranial hypertension appears to be an important mechanism in at least a subgroup of patients with IIH. Among these patients, 78% had complete relief or improvement of their main presenting symptoms after endovascular stenting. Resolution or improvement in papilledema was seen in 85.1% of patients. Endovascular stenting should be considered whenever venous sinus stenosis is diagnosed in patients with IIH.

Background and purposeWhile recent literature has described the prevalence of transverse sinus stenosis in patients with idiopathic intracranial hypertension, tinnitus, and refractory headaches, it is unclear what the prevalence is in the general population. This study evaluates the prevalence of venous sinus stenosis and hypoplasia in the general patient population.Materials and methods355 of 600 consecutive patients who underwent CT angiography of the head met the inclusion criteria. The diameters of the dural venous sinuses were recorded. Each study was evaluated by a neuroradiologist for the presence of stenoses. Univariate and multivariate statistical analyses were performed by a statistician.ResultsThe prevalence of unilateral transverse sinus stenosis or hypoplasia in a sample of patients representing the general population was 33%, the prevalence of bilateral transverse sinus stenosis was 5%, and the prevalence of unilateral stenosis with contralateral hypoplasia was 1%. A multivariate analysis identified arachnoid granulations as a predictor of stenosis (p<0.001). Gender trended toward significance (p=0.094). Race was not a significant predictor of stenosis (p=0.745).ConclusionsThe prevalence of bilateral transverse sinus stenosis in the general population is not trivial. These data may be used as a reference for understanding the mechanistic role of stenoses in idiopathic intracranial hypertension, tinnitus, and refractory headaches.

AbstractIdiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disease primarily affecting obese women of child-bearing age, typically presenting with positional headaches, diplopia from abducens nerve palsies, pulse-synchronous tinnitus, and visual disturbances related to papilledema, including transient visual obscurations, blurry vision, and visual field defects. Controversy remains regarding the pathophysiology of IIH. Elevated intracranial pressure in IIH is thought to be the result of a dysregulation of cerebrospinal fluid (CSF) dynamics, through excessive secretion, reduced drainage, or both. Passive CSF drainage through the arachnoid granulations depends on a pressure gradient between the subarachnoid space and the cerebral venous system, such that elevations in cerebral venous pressure lead to impaired CSF drainage. Dural venous sinus stenosis (DVSS) at the junction of the transverse and sigmoid sinuses, leading to local venous hypertension and a secondary reduction in CSF drainage through the arachnoid granulations, is increasingly recognized as an important component of the pathophysiology of IIH. A growing number of studies have demonstrated a role for stenting of DVSS as an alternative to CSF shunting and optic nerve sheath fenestration in medically refractory IIH patients with vision loss or debilitating symptoms.

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.

BackgroundThe effect of dural venous sinus stenting has been investigated for the treatment of idiopathic intracranial hypertension (IIH) but the effect of stenting on the long-term patency of the cortical draining veins, especially the vein of Labbé (VOL), remains unknown.MethodsWe reviewed our database of 38 patients with IIH with 41 stented dural venous sinuses between October 2006 and December 2014. Demographic, clinical, and radiological data were reviewed. Follow-up catheter angiographic data were included when available.ResultsStent placement spanned the ostium of the VOL in 35 patients (92.1%), with no immediate effect on the drainage of the VOL. Follow-up angiography (mean 35.1 months, range 1.7–80.7 months) was available in 24 patients, 21 of whom had stents spanning the VOL ostium. The VOL remained patent without occlusion or drainage alteration in all 21 patients. There were no immediate or long-term intracranial complications.ConclusionsDural venous sinus stenting for patients with IIH does not affect the immediate or long-term patency of the VOL and is not associated with intracranial complications.
