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.

Objective: To explore the diagnosis of cerebral venous sinus stenosis (CVSS) in idiopathic intracranial hypertension (IIH), and to evaluate the efficacy and risk of venous sinus stenting treatment for CVSS. Methods: 40 patients with refractory IIH complicated with CVSS underwent examination with magnetic resonance venography (MRV), digital subtraction angiography (DSA) and direct retrograde cerebral venography and manometry to confirm morphologic features of IlH and measure venous pressure.The CSF pressure on lumbar puncture ranged from 250 to 500 mmH 2 O with normal composition. All patients had headache, and funduscopic examination demonstrated papilledema for all patients. 28 patients who showed severe stenosis of venous sinuses with the pressure gradient across the stenosis >100 mmH 2 O were treated with venous sinus stenting and were followed-up for more than 12 months.Intrasinus pressures were recorded before and after the procedure and correlated with clinical outcome during the follow-up period. Results: Sinus stenting angioplasty was successful in all 28 patients.In all patients venous sinus stenosis was improved after stenting procedure (the residual stenosis rate<20%) and intrasinus pressure was reduced (the pressure gradient vanished or<20 mmH 2 O ).The clinical symptoms in all the patients were improved or disappeared at discharge and intracranial pressures were normalized within 3 months after the procedure.During the follow-up period of (16.3±11) months (range 12 to 36 months),no patient had recurrence of IIH.In all cases, DSA or MRV was performed at 12-month follow-up and demonstrated the absence of sinus thrombosis or in-stent stenosis. Conclusions: Patients with refractory IIH should be assessed for CVSS. MRV or DSA was recommended for these patients as a routine work-up.Cerebral venography and manometry are helpful to evaluate the relation between venous outflow obstruction and intracranial hypertension.If severe CVSS is presented in patients who experienced medical treatment failure, endovascular stent placement could be an alternative to classic surgical approaches. Additional randomized and controlled clinical research is deserved.

Introduction: Idiopathic intracranial hypertension (IIH) is one of the most common causes of papilloedema seen by ophthalmologists and neurologists. Patients with IIH routinely undergo lumbar puncture (LP) for diagnosis. Dural venous sinus thrombosis (DVST) is a rare complication of cerebrospinal fluid pressure (CSF)-lowering procedures such as lumbar puncture and epidural and may be an intracranial complication of IIH. Case Description: A 29-year-old obese woman was diagnosed with severe idiopathic intracranial hypertension (IIH) after she presented with new-onset headache, pulsatile tinnitus and blurred vision. Magnetic resonance imaging (MRI) and venography (MRV) were normal apart from signs of intracranial hypertension. Lumbar puncture (LP) revealed an opening pressure of 40 cm of water. Due to the severity of the papilloedema and vision loss, she was referred for a ventriculoperitoneal shunt and found to have venous sinus thrombosis involving the superior sagittal sinus on the pre-operative computed tomography (CT) head 5 days after the LP. CT venography (CTV) one day later and MRV 3 days later showed significant worsening as the thrombosis extended into the deep venous system. She was started on therapeutic heparin and her symptoms and vision improved and she did not develop any neurological complications. Conclusions: DVST should be considered in IIH patients who have worsening papilloedema or symptoms of intracranial hypertension. Repeat venous imaging can prevent devastating consequences such as venous infarcts of haemorrhage in these patients.

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.

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.

Background: The clinical presentation of cerebral venous sinus thrombosis (CVST) overlaps with that of idiopathic intracranial hypertension (IIH), but no screening tool exists. We investigated the role of eye-neck integrated ultrasound in the diagnosis and differentiation of IIH and CVST.Methods: Twenty IIH patients, 30 CVST patients, and 40 healthy controls were retrospectively analyzed. The ultrasonographic optic nerve sheath diameter (ONSD) and hemodynamic characteristics of the internal jugular veins (IJVs) were recorded. The cerebrospinal fluid opening pressure was measured after ultrasonic examination.Results: The ONSD was significantly larger in IIH patients than in controls (4.71 ± 0.41 vs. 3.93 ± 0.24 mm, p &lt; 0.001). The ONSD cut-off for IIH diagnosis was 4.25 mm (AUC = 0.978; 95% CI: 0.95–1.0, p &lt; 0.001, sensitivity: 90%, specificity: 93%). In the CVST group, 22 (73.3%) patients had elevated intracranial pressure (ICP); the mean ONSD was significantly higher in patients with increased ICP than in those without (4.43 ± 0.33 vs. 3.95 ± 0.17 mm, p &lt; 0.001). The mean blood flow volume (BFV) was significantly reduced in CVST patients (425.17 ± 349.83 mL/min) compared to that in controls (680.37 ± 233.03 mL/min, p &lt; 0.001) and IIH patients (617.67 ± 282.96 mL/min, p = 0.008). The optimal BFV cut-off for predicting CVST was 527.28 mL/min (AUC = 0.804, 95% CI: 0.68–0.93, p &lt; 0.001, sensitivity: 80%, specificity: 78%). The velocity of the unilateral IJVs-J3 segment decreased or remained constant during deep inspiration (abnormal respiratory modulate blood flow test, ARMT) in 32.5% of controls, with no bilateral ARMT. The prevalence of bilateral ARMT was 25% in IIH patients (χ2 = 12.9, p = 0.005) and 27% in CVST patients (χ2 = 17.6, p = 0.001).Conclusion: Eye-neck integrated ultrasound is an easily available bedside technique to assess ICP and hemodynamic characteristics of IJVs. ONSD measurement can identify patients with increased ICP, and reduced IJV BFV may aid the differentiation of CVST and IIH.

BackgroundDural venous sinus stenting (VSS) is an effective treatment for idiopathic intracranial hypertension (IIH) in adult patients. There are no published series to date evaluating safety and efficacy of VSS in pediatric patients.ObjectiveTo report on procedural device selection and technique as well as safety and efficacy of VSS for pediatric patients with medically refractory IIH due to underlying venous sinus stenosis.MethodsA multi-institutional retrospective case series identified patients with medically refractory IIH aged less than 18 years who underwent VSS.Results14 patients were identified at four participating centers. Patient ages ranged from 10 to 17 years, and 10 patients (71.4%) were female. Mean body mass index was 25.7 kg/m2 (range 15.8–34.6 kg/m2). Stenting was performed under general endotracheal anesthesia in all except two patients. The average trans-stenotic gradient during diagnostic venography was 10.6 mm Hg. Patients had stents placed in the superior sagittal sinus, transverse sinus, sigmoid sinus, occipital sinus, and a combination. Average follow-up was 1.7 years after stenting. Six patients out of 10 (60%) had reduced medication dosing, 12 of 14 patients (85.7%) had improvements in headaches, two patients (100%) with pre-stent tinnitus had resolution of symptoms, and four (80%) of five patients with papilledema had improvement on follow-up ophthalmological examinations. Two patients (14.3%) developed postprocedural groin hematomas, one patient (7.1%) developed a groin pseudoaneurysm, and one patient (7.1%) had postprocedural groin bleeding. No other procedural complications occurred. Four patients (28.6%) required further surgical treatment (cerebrospinal shunting and/or stenting) after their first stenting procedure.ConclusionsThis series suggests that VSS is feasible in a pediatric population with IIH and has a low complication rate and good clinical outcomes.

Dural Venous Sinus

Background Idiopathic intracranial hypertension (IIH) is a syndrome defined by elevated intracranial hypertension without radiographic evidence of a mass lesion in the brain. Dural venous sinus stenosis has been increasingly recognized as a treatable cause, and dural venous sinus stenting (DVSS) is increasingly performed. Methods A 5 year single-center retrospective analysis of consecutive patients undergoing DVSS for medically refractory IIH. Results There were 43 patients with a mean imaging follow-up of 6.5 months and a mean clinical follow-up period of 13.5 months. DVSS was performed as the first procedure for medically refractory IIH in 81.4% of patients, whereas 18.6% of patients included had previously had a surgical procedure (ventriculoperitoneal (VP) shunt or optic nerve sheath fenestration (ONSF)). Headache was present in all patients and after DVSS improved or remained stable in 69.2% and 30.8%, respectively. Visual acuity changes and visual field changes were present in 88.4% and 37.2% of patients, respectively. Visual field improved or remained unchanged in 92%, but worsened in 8% after stenting. There was a stent patency rate of 81.8%, with an 18.2% re-stenosis rate. Of the 43 procedures performed, there was a 100% technical success rate with zero major or minor complications. Conclusion Based on this single-center retrospective analysis, DVSS can be performed with high technical success and low complication rates. A majority of patients presented primarily with headache, and these patients had excellent symptom relief with DVSS alone. Patients presenting with visual symptoms had lower success rates, and this population, if stented, should be carefully followed for progression of symptoms.

Dural Venous Sinus

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.
