BackgroundLong term failure rates after venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH) are poorly understood.MethodsRetrospective analysis was performed on a prospectively-maintained single center database to identify patients with medically refractory IIH who underwent VSS. Patients with persistent or severe recurrent symptoms after VSS undergo lumbar puncture (LP), therefore LP serves as a marker for treatment failure.Results81 patients underwent VSS with a mean follow-up of 10 months; 44 (54.3%) patients underwent LP after VSS due to persistent or recurrent symptoms at a mean of 12 months (median 7, range 2–43). There was a mean decrease in opening pressure (OP) on LP from pre- to post-VSS of 9.1 cm H2O (median 9.5). Overall, a total of 21 (25.9%) patients underwent further surgical intervention following VSS, including five who underwent repeat VSS (6.2% of total) and 18 who underwent cerebrospinal fluid shunting (22.2% of total). There was a non-significant (p=0.18) but overall increase in quality of life scores from pre-stenting (61.2) to last follow-up (71.2), and a significant decrease in Headache Impact Test-6 (HIT-6) scores (p=0.03) with mean pre-stenting and last follow-up scores of 62.7 and 55.8, respectively.ConclusionsVSS is an effective treatment for venous sinus stenosis in IIH; however, this study found higher rates of symptomatic recurrence and need for further surgical intervention (26%) than previously reported in the literature. Recurrence of symptoms occurred at a median of 7 months, even though OP remained lower at follow-up LP, suggestive of a re-equilibration phenomenon.

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.

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.

Purpose Transverse sinus stenosis is commonly seen in patients with idiopathic intracranial hypertension. It is not clear whether it is the cause or the result of idiopathic intracranial hypertension. Stenting for idiopathic intracranial hypertension has been carried out in several prior series. Our goal was to evaluate the clinical and imaging follow-up results of patients with idiopathic intracranial hypertension that underwent stenting for this condition at our center. Materials and Methods We reviewed the clinical, venographic and follow-up imaging data in patients who underwent elective transverse sinus stenting during the period from 2011 to 2017. Results In total, 18 patients with idiopathic intracranial hypertension were identified. The mean lumbar cerebrospinal fluid opening pressure recorded was 408 mmH20. Overall, 16 patients met the inclusion criteria and underwent transverse sinus stenting. At venography, the mean pressure gradient across the dominant transverse sinus stenosis was 21 mmHg. The pressure gradient immediately after stenting in all of those measured was negligible. Following stenting, headaches improved in 10 of the 16 cases, with persistent headaches in four patients, one of which had persistent baseline migraines. All cases showed resolution of the papilledema on follow up. Follow-up imaging with computed tomography venography showed that the stents remained widely patent. The follow up in clinic was done for a mean period of 35.5 months. Follow up with computed tomography venography was done for a mean of 10.3 months. Conclusion Venous sinus stenting is a safe and effective procedure. It relieves papilledema in all cases and improves headaches in most cases.

BackgroundCerebral 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.MethodsWe reviewed our clinical database of patients with a diagnosis of IIH, who underwent stenting of stenotic transverse or transverse/sigmoid sinus junction. Patients who had follow-up CTVs after more than 30 days were included in the final study group. All CTVs were reviewed by two readers for in-stent thrombosis, extrinsic stent compression, juxta-stent stenosis, and new contralateral venous sinus stenosis. Inter-observer agreement and association of stent patency with clinical outcomes (headache and papilledema) were assessed.ResultsIn all 36 included patients with 38 cerebral venograms for stenting, follow-up CTVs demonstrated adequate opacifications of the venous sinuses and stents for confident evaluation for in-stent thrombosis, extrinsic stent compression, juxta-stent stenosis, and new contralateral venous sinus stenosis, with inter-observer agreement coefficient of 0.7, 1.0, 0.8, and 1.0 respectively. Association between abnormal CTV and higher rates of persistent headache and lower rates of headache improvement/resolution was statistically significant (P-value of 0.01).ConclusionCTV is a reliable noninvasive imaging modality for evaluation of cerebral venous sinuses and stent patency following treatment of idiopathic intracranial hypertension with venous sinus stenting and could be used as a routine follow-up study.

Abstract BACKGROUND The short- and long-term impact of cerebrospinal fluid shunting on quality of life (QoL) in idiopathic normal pressure hydrocephalus (INPH) is poorly understood. OBJECTIVE To investigate QoL in shunted INPH patients compared to the population and to investigate which factors influence QoL in INPH. METHODS INPH patients consecutively shunted in Sweden during 2008-2010 were scrutinized. Population-based controls were age- and sex-matched to the patients. Included participants were the following: 176 INPH patients and 368 controls. QoL was assessed using the EuroQol 5-dimension 5-level (EQ5D5L) instrument, which measures overall QoL and health status in 5 dimensions. Independency (accommodation and/or need for in-home care) and comorbidities were assessed. Patients were followed up 6-45 mo after surgery (mean follow-up time: 21 mo). RESULTS Shunting improved QoL (P < .001) and health status in all dimensions (P < .005). Shunted INPH patients had lower QoL than controls (P < .001). The patients’ health status in mobility, self-care, daily activities, and anxiety/depression was worse than the controls both before and after surgery (P < .001). The main predictors of low QoL in INPH were symptoms of depression (P < .001) and severity of gait disturbance (P = .001). Fewer INPH patients than controls lived independently (45% vs 85%, P < .001). Time after shunting had no influence on QoL. CONCLUSION QoL remains improved in shunted INPH patients at a mean follow-up time of 21 mo, but the patients do not reach the same QoL as the population. Symptoms of depression and severity of gait disturbance are the strongest predictors of low QoL in INPH.

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.

OBJECTIVESymptomatic intracranial hypertension can be caused by cerebral venous sinus stenosis (CVSS) and cerebral venous sinus thrombotic (CVST) stenosis, which is usually found in some patients with idiopathic intracranial hypertension (IIH). Recently, at the authors’ center, they utilized intravascular ultrasound (IVUS) as an adjunct to conventional venoplasty or stenting to facilitate diagnosis and accurate stent placement in CVSS.METHODSThe authors designed a retrospective review of their prospective database of patients who underwent IVUS-guided venous sinus stenting between April 2016 and February 2017. Clinical, radiological, and ophthalmological information was recorded and analyzed. IVUS was performed in 12 patients with IIH (9 with nonthrombotic CVSS, 3 with secondary stenosis combined with CVST) during venoplasty through venous access. The IVUS catheter was used from a proximal location to the site of stenosis. Post-stenting follow-up, including symptomatic improvement, stent patency, and adjacent-site stenosis, was assessed at 1 year.RESULTSThirteen stenotic cerebral sinuses in 12 patients were corrected using IVUS-guided stenting. No technical or neurological complications were encountered. The IVUS images were excellent for the diagnosis of the stenosis, and intraluminal thrombi were clearly visualized by using IVUS in 3 (25%) of the 12 patients. A giant arachnoid granulation was demonstrated in 1 (8.3%) of the 12 patients. Intravenous compartments or septations (2 of 12, 16.7%) and vessel wall thickening (6 of 12, 50%) were also noted. At 1-year follow-up, 10 of 12 patients were clinically symptom-free in our series.CONCLUSIONSIVUS is a promising tool with the potential to improve the diagnostic accuracy in IIH, aiding in identification of the types of intracranial venous stenosis, assisting in stent selection, and guiding stent placement. Further study of the utility of IVUS in venous stenting and venous stenosis pathology is warranted.
