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...

This case series aimed to review the significance of revisiting papilledema after successful cerebral venous sinus thrombosis (CVST) management with sinus angioplasty. Four patients presented with blurring and transient obscuration of vision with papilledema, headache, tinnitus, and vomiting. On magnetic resonance venography and digital subtraction angiography, chronic transverse sinus thrombosis was diagnosed for which patients underwent endovascular intervention (stenting). After the resolution of CVST, patients developed the recurrence of symptoms which on digital subtraction angiography revealed dural arteriovenous malformation (DAVM)...

OBJECTIVES: When drainage of an anomalous pulmonary vein is high into the superior vena cava (SVC), traditional techniques of 1-patch or 2-patch repair may be challenging. The cavoatrial anastomosis technique (the Warden procedure) was developed to reduce the risk of sinus node dysfunction and SVC obstruction. Herein, we describe the outcomes of the Warden procedure in children at a single institution. METHODS: A retrospective study was conducted on all children with partial anomalous pulmonary venous drainage (PAPVD) undergoing the Warden procedure from 1996 to 2015...

Fifty-four year-old man with recent history of myocardial infarction and a percutaneous coronary intervention who suffered a ventricular fibrillation arrest at home. He was resuscitated in the field. His heart rhythm was in atrial fibrillation. The cardiac catheterization showed a patent stent from his previous myocardial infarction and no new occlusions. He subsequently underwent hypothermia protocol using the Alsius CoolGard 3000 Temperature Control System and Icy Catheter. Heparin drip was started for atrial fibrillation 36 hours after catheter insertion and became therapeutic 2 hours before the end of cooling maintenance phase...

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...

We report a case in which an intracranial dural arteriovenous fistula (DAVF) developed after endovascular treatment of a patient with idiopathic intracranial hypertension with venous sinus stenting (VSS). The pathogenesis may involve hemodynamic alterations secondary to increased poststenting venous sinus pressure, which may cause new arterial ingrowth into the fistulous sinus wall without capillary interposition. Despite administration of dual antiplatelet therapy, there may also be subclinical cortical vein thrombosis that contributed to DAVF formation...

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...

PURPOSE: Iliocaval obstruction is a substantial contributor to chronic venous insufficiency and is increasingly being treated endovascularly with angioplasty and stent placement. Utilization of an appropriate stent for treatment is pivotal; however, until today, mechanical properties of venous stents remain unknown. MATERIALS AND METHODS: We analyzed the radial resistive force, the chronic outward force, as well as the crush resistance of seven stent models [Zilver Vena (Cook, Bjaeverskov, Denmark), Sinus Venous, Sinus Obliquus and Sinus XL Flex (Optimed, Ettlingen, Germany), Vici (Veniti; St...

OBJECTIVE: Minimally invasive interventions by recanalization, percutaneous transluminal angioplasty, and stenting in post-thrombotic syndrome (PTS) obstructions and iliac vein compression syndrome (IVCS) have shown good results. Until recently, no dedicated venous stents were available, and stent-related issues accounted for a decrease in patency scores. The introduction of dedicated stents with more flexibility and higher radial forces could result in higher patency scores. This study focused on the outcomes of patients treated by a dedicated sinus-Venous stent (OptiMed GmbH, Ettlingen, Germany)...

RATIONALE: The superior sagittal sinus (SSS) and transverse sinus are the major dural sinuses that receive a considerable amount of venous drainage. The occlusion of them has been suggested to cause intracranial hypertension, hemorrhage, and lead to potentially fatal consequences. PATIENT CONCERNS: We reported a 35-year-old woman with headache presented to our emergency department with a decreased level of consciousness and epileptic seizures. The examination of speech, higher mental function, and cranial nerve were normal...

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...

PURPOSE OF REVIEW: To identify long-term management strategies and outcomes for the treatment of spontaneous cerebrospinal fluid (CSF) rhinorrhea related to idiopathic intracranial hypertension (IIH). RECENT FINDINGS: Adjuvant treatments following surgical repair of spontaneous CSF leaks are aimed at normalizing intracranial pressure (ICP) to minimize the risk of recurrence. IIH is closely linked to obesity, and growing evidence suggests that weight loss, both through conservative and surgical approaches, is effective at addressing the root cause of this disorder...

Purpose Anticoagulation is the first-line therapy for cerebral venous sinus thrombosis (CVT). Endovascular treatment is increasingly applied in patients deteriorating despite anticoagulation with extensive thrombosis or contraindications for anticoagulation. Experience with stent retrievers in CVT is limited. Results We present three cases of severe CVT treated with stent-retrievers, thrombus aspiration and local thrombolysis. In two patients with extensive thrombosis, a partial recanalization was achieved, but only one of them showed significant improvement...
