Background: Idiopathic intracranial hypertension (IIH) is primarily a disorder of young obese women of unknown etiology. The clinical presentation of IIH is similar to that of sinus thrombosis. The incidence of transverse sinus stenosis (TSS) reaches up to 90% of patients with IIH compared with normal subjects, and venous sinus thrombosis was reported in 11.4% of patients previously diagnosed as having IIH. Patients with thrombosis showed an abnormal region of double- track pattern on gadolinium (Gd) - enhanced T1WI within the dural sinus...

We report a case of transverse sinus-sigmoid sinus dural arteriovenous fistula(T-S dAVF)with venous flow congestion, which was accompanied by sigmoid sinus stenosis and treated with percutaneous transluminal sinus stenting. A 76-year-old woman presented with dementia and disturbance of consciousness. Magnetic resonance imaging(MRI)on admission revealed subcortical edema in the left occipital lobe and angiography demonstrated a left T-S dAVF with right transverse sinus occlusion and sigmoid sinus stenosis. Hemodynamics of the shunt flow from several feeders demonstrated retrograde flow to the straight sinus and superior sagittal sinus, and antegrade flow into the left internal jugular vein...

INTRODUCTION: Venous outflow obstruction is recognized as a contributing factor in a subset of patients with idiopathic intracranial hypertension (IIH). Little is known about venous sinus waveform morphology or how it changes after stenting. METHODS: Fifteen patients with IIH underwent waveform recording during catheter venography and manometry. Ten patients (Group A) with venous sinus stenosis and pressure gradient ≥7 mm Hg underwent waveform recording during awake venography and during stenting under general anesthesia...

OBJECTIVE The role of venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH) is not well understood. The aim of this systematic review is to attempt to identify subsets of patients with IIH who will benefit from VSS based on the pressure gradients of their venous sinus stenosis. METHODS MEDLINE/PubMed was searched for studies reporting venous pressure gradients across the stenotic segment of the venous sinus, pre- and post-stent pressure gradients, and clinical outcomes after VSS. Findings are reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines...

Background: The pattern of cranial venous drainage in syndromic craniosynostosis is unpredictable and not adequately understood. Collateral channels substitute for stenotic venous sinuses and pose potential risk for surgical intervention. The purpose of this study was to analyze the patterns of venous drainage in patients with syndromic craniosynostosis and their influence on operative planning and morbidity. Methods: A retrospective study of patients with syndromic craniosynostosis from 2000 to 2013 was performed...

Nephrotic syndrome is a prothrombotic state with predisposition to venous sinus thrombosis and arterial vascular stroke. Watershed infarcts in junction of arterial territory develop in hypotensive hypovolemic state. These border zone infarcts are usually bilateral in the absence of unilateral arterial stenosis or microembolism. We report a 6-year-girl of frequently relapsing nephrotic syndrome who developed sudden onset hemiparesis with aphasia. Magnetic resonance (MR) imaging brain revealed unilateral watershed infarct in territory between the major cerebral arterial vessels with evidence of restricted diffusion and normal vessel anatomy on MR angiography...

We report a patient with hypertrophic pachymeningitis and symptomatic stenosis of the superior sagittal sinus. A 71-year-old man presented with right hemiparesis, sensory-dominant aphasia, and right hemispatial neglect that had been worsening over 2 weeks. Computed tomography showed isodense crescent-shaped lesions deforming the surface of the left cerebral hemisphere, mimicking a subdural hematoma with atypical perifocal edema in the left parietal lobe. Magnetic resonance imaging showed diffuse thickening of the dura mater with contrast enhancement of his left cerebral hemisphere...

A 46-year-old man presented with severe visual loss and optic atrophy associated with optociliary shunt vessels. The diagnostic work-up revealed intracranial hypertension and cerebral venous sinus stenosis, with no evidence of previous thrombosis. In view of the severe visual dysfunction, both eyes were submitted to optic nerve sheath fenestration. After surgery, a regression of collateral vessels was observed in both eyes.

BACKGROUND AND PURPOSE: Type I and IIa dural arteriovenous fistulas (DAVFs) have a low hemorrhagic risk, but are often the cause of debilitating tinnitus that requires treatment. While Onyx® and PHIL™ (Precipitating hydrophobic injectable liquid) transarterial embolization represent the first endovascular option, there are occasional cases where performing angioplasty and stenting of the affected sinus may lead to satisfactory results. MATERIAL AND METHODS: We retrospectively analyzed four consecutive cases of patients with DAVF-induced pulsatile tinnitus secondary to type I and II DAVFs who were treated with angioplasty and stenting of the sinus only...

A 4-year-old male with headaches, papilledema, intracranial hypertension, and bilateral transverse sinus (TS) stenosis underwent attempted percutaneous placement of a right TS stent. Stent deployment was not technically feasible due to the stiffness of the stent and tortuosity of the patient's jugular bulb. Therefore, the patient underwent hybrid endovascular stenting of the right TS using neuronavigation and direct access of the TS following a single burr hole craniectomy. Two Express 8 mm × 17 mm balloon-mounted stents were deployed into the right TS, which resulted in obliteration of the preexisting trans-stenosis pressure gradient and decreased intracranial parenchymal pressure as monitored through an intracranial pressure bolt...

BACKGROUND: Dural 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. METHODS: We 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. RESULTS: Comparison of pre-stent 3DRV with post-stent contrast-enhanced flat panel detector CT allowed confirmation of stent placement and the result of stenosis dilation...

The present study reports the effect of successful treatment of cerebral venous sinus thrombosis (CVST) with stent retriever thrombectomy combined with local thrombolytic therapy. Medical records of 29 patients were retrospectively analyzed following a diagnosis of CVST with magnetic resonance venography (MRV) or digital subtraction angiography (DSA). Systemic anticoagulation was the initial treatment in all patients following admission. In group A, stent retriever thrombectomy combined with local thrombolytic therapy was performed on 14 patients who met the criteria of endovascular therapy...

Chiari type 1 malformation (CM1) rarely causes papilloedema, which is indicative of high intracranial pressure with or without ventricular dilatation. Furthermore, concomitant brain parenchymal abnormalities have not been reported to date. In this paper, the authors report on a young woman of CM1-induced intracranial hypertension (ICH) with diffuse brain edema with a focus on venous sinus assessment, and discuss the surgical strategy. A 24-year-old woman presented to Nagoya University Hospital complaining of 4-year history of severe occipital headache and blurry vision with slowly progressive worsening...

OBJECTIVE Idiopathic intracranial hypertension (IIH) is commonly associated with venous sinus stenosis. In recent years, transvenous dural venous sinus stent (DVSS) insertion has emerged as a potential therapy for resistant cases. However, there remains considerable uncertainty over the safety and efficacy of this procedure, in particular the incidence of intraprocedural and delayed complications and in the longevity of sinus patency, pressure gradient obliteration, and therapeutic clinical outcome. The aim of this study was to determine clinical, radiological, and manometric outcomes at 3-4 months after DVSS in this treated IIH cohort...

BACKGROUND: Venous outflow obstructions are rare anatomic findings that can appear with symptoms of elevated intracranial pressure, including headache and vision loss, and can be mistaken for more common diagnoses, such as idiopathic intracranial hypertension (IIH) or cerebral venous sinus thrombosis (CVST). Although venous outflow obstructions have been reported in rare bone dysplasias and congenital abnormalities, to date they have not been reported in renal osteodystrophy (ROD), a relatively common disorder seen in patients with chronic kidney disease...

Children are particularly at risk for stroke in the neonatal period. Neonatal hemorrhagic stroke is rarer than ischemic stroke. The incidence is 40.7/100 000 live births. Hemorrhagic stroke is caused by a disruption in venous drainage usually due to local thrombosis. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is a cerebral seizure during the first week of life. Therefore, stroke should be ruled out by diagnostic imaging in the case of any seizure in the first days of life...
