BACKGROUND: Lateral sinus stenosis is a little-known cause for pulsatile tinnitus (PT). In several small series, stenting has been described as an effective treatment for disabling PT linked with this type of stenosis. OBJECTIVES: To describe the clinical, radiological, and manometric characteristics of patients treated for disabling PT by lateral sinus stenosis. Assessment of the efficacy of stenting for this indication. METHODS: Retrospective study of patients treated for isolated PT by stenting of a lateral sinus stenosis in our institution, between 2009 and 2015...

We report a case of a 39-year-old man presenting with a high-grade left parieto-occipital arteriovenous malformation (AVM) complicated by superior sagittal sinus (SSS) stenosis, seven years after the first presentation. Magnetic resonance imaging revealed a newly developed perilesional edema. Venous sinus stenosis acutely progressed to occlusion and induced multiple intracerebral hemorrhages. An emergent balloon venoplasty of the SSS successfully recanalized the thrombosed sinus. Further, multistage transarterial nidus embolization was performed followed by surgical resection, resulting in a complete eradication of the large AVM...

In the field of dysmorphology, achondroplasia is a well-known disorder. Sinus pericranii (SP), however, is not. The latter condition is a rare vascular malformation characterized by abnormal connections between the intracranial and the extracranial venous drainage pathways. The etiology of SP remains unclear, and yet, these defects can be present at birth, develop spontaneously later, or evolve following head trauma. Here, we report on a 2-year-old male with achondroplasia, SP, and craniocervical junction stenosis...

BACKGROUND: Pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension (IIH), is a condition associated with increased intracranial pressure (ICP) in the absence of radiographic findings such as mass lesions or cerebral edema. CASE DESCRIPTION: We describe a case of progressive headache and visual disturbances attributed to PTC that resulted from subacute superior sagittal sinus (SSS) stenosis by a metastatic tumor. CONCLUSIONS: Venous outflow obstruction often presents with an acute symptomatology including infarcts, hemorrhages, and seizures, but only rarely does it cause the progressive development of raised ICP...

We present a rare case of dural arteriovenous fistula (DAVF) with subarachnoid hemorrhage and intraventricular hemorrhage due to its venous aneurysms. A 63-year-old woman was admitted for a sudden loss of consciousness. Computed tomography angiograph, magnetic resonance imaging angiography, and digital subtraction angiography revealed a superior sagittal sinus DAVF. The fistula was fed by the left middle meningeal artery and left internal carotid artery, and was drained by a right vein of Trolard, the superficial Sylvian vein, deep Sylvian vein, and basal vein to the vein of Galen...

Stenosis of the transverse sinus (TS) and sigmoid sinus (SS), with a trans-stenosis pressure gradient, has been implicated in the pathophysiology of idiopathic intracranial hypertension (IIH). MRI has shown improvement in TS and SS stenosis after high-volume lumbar puncture (HVLP) in a subset of patients with IIH. The authors present the first report of an IIH patient with immediate post-HVLP TS and SS trans-stenosis pressure gradient reduction and an attendant increase in TS and SS cross-sectional area confirmed using intravascular ultrasonography (IVUS)...

OBJECTIVE The evaluation of the venous neurovasculature, especially the dural venous sinuses, is most often performed using MR or CT venography. For further assessment, diagnostic cerebral angiography may be performed. Three-dimensional rotational angiography (3D-RA) can be applied to the venous system, producing 3D rotational venography (3D-RV) and cross-sectional reconstructions, which function as an adjunct to traditional 2D digital subtraction angiography. METHODS After querying the database of Baylor St...

RATIONALE: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesis is that PNSAH is venous in origin. Intracranial venous hypertension has been considered as the pivotal factor in the pathogenesis of PNSAH...

INTRODUCTION: Dural venous sinus stenosis (DVSS) may lead to increased intracranial pressure, sometimes requiring a stent if a high pressure gradient exists. Many neuroendovascular physicians use microcatheters to measure gradients, yet there are no studies comparing the accuracies and precisions of modern day microcatheters. We examined pressure recordings from five commonly used microcatheters in an experimental DVSS model. METHODS: Using a programmable pump, dynamic flow was established in a closed circuit mimicking the venous sinus waveform...

BACKGROUND AND PURPOSE: Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group...

Accurate diagnosis of subtypes of transverse sinus (TS) hypoplasia requires more expensive methods like magnetic resonance (MR) imaging. We hypothesized ultrasound findings of the internal jugular vein (IJV) can be surrogate indicators for diagnosis of TS hypoplasia. MR images were reviewed in 131 subjects to evaluate TS diameter and the location and degree of venous flow stenosis and obstruction. Ultrasound parameters including the cross-sectional lumen area (CSA), time-average-mean velocity (TAMV), and flow volume (FV) at each IJV segment were also evaluated...

BACKGROUND: A subset of patients with skull base cerebrospinal fluid (CSF) leaks are found to have elevated intracranial pressure (ICP). In these patients, elevated ICP is thought to contribute to both the pathophysiology of the leak as well as postoperative leak recurrences. Current strategies for post-operative ICP control include medical therapy and shunting procedures. The aim of this study is to report the use of venous sinus stenting (VSS) in the management of patients with skull base CSF leaks due to elevated ICP...

OBJECTIVE: Venous sinus stenting (VSS) is a safe and effective treatment for idiopathic intracranial hypertension (IIH) with angiographic venous sinus stenosis. However, predictors of stent-adjacent stenosis (SAS) remain poorly defined. METHODS: We performed a retrospective review of 47 patients with IIH and intracranial venous stenosis who underwent VSS with pre- and post-stent venography. Patient characteristics, treatments and outcomes were reviewed. Changes in pressure gradient after VSS were classified according to pattern of gradient resolution into types I-III...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterised by an increased intracranial pressure (ICP) in the absence of any central nervous system disease or structural abnormality and by normal CSF composition. Management becomes complicated once surgical intervention is required. Venous sinus stenosis has been suggested as a possible aetiology for IIH. Venous sinus stenting has emerged as a possible interventional option. Evidence for venous sinus stenting is based on elimination of the venous pressure gradient and clinical response...

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT)...

INTRODUCTION: Medical treatment, cerebrospinal fluid (CSF) shunting, and optic nerve sheath fenestration are standard treatments for increased intracranial pressure (ICP) in patients with idiopathic intracranial hypertension (IIH). Venous sinus stenting provides a novel alternative surgical treatment in cases of venous sinus stenosis with elevated ICP. METHODS: 12 consecutive subjects with papilledema, increased ICP, and radiological signs of dural sinus stenosis underwent cerebral venography and manometry...

BACKGROUND: Elevated body mass index (BMI) has been correlated with worse outcomes after treatment for idiopathic intracranial hypertension (IIH). Venous sinus stenting (VSS) has emerged as a safe and effective treatment for a subset of patients with IIH and evidence of venous sinus stenosis. However, the association between BMI and the efficacy of VSS remains poorly characterized. OBJECTIVE: To determine, in a retrospective cohort study, the effect of BMI on preoperative mean intracranial venous pressure (MVP) and post-VSS outcomes...

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum...
