Venous thromboembolism (VTE) remains among the leading causes of maternal mortality in the developed world, presenting variably as deep vein thrombosis (DVT), pulmonary embolism (PE) or cerebral vein thrombosis (CVT), among others. Obesity in particular has been recognized as the principal contributing factor to the risk of VTE in pregnancy and with the global increase in the rates of obesity affecting reproductive age women, heightened awareness of the risk and consequences of VTE in this population are vital...

BACKGROUND: The extradural temporopolar transcavernous approach can be used to treat central skull base pathologies, but control of bleeding from the opened cavernous sinus is essential. Oxidized cellulose cotton packing and fibrin glue injection can be used, but the effect on the postoperative venous draining pattern remains unclear. OBJECTIVE: To investigate changes in the venous drainage pattern immediately after transcavernous surgery with and without fibrin glue injection into the bleeding cavernous sinus...

Recirculation, from arterial inflow routes through venous outflow pathways, was conceptualized in stroke research 50 years ago. As new technologies were developed, blocked arteries could be reopened, capillaries could be reperfused, and the use of recanalization and reperfusion grew to dominate therapeutic strategies. These approaches overwhelmingly focused on restoration of arterial and capillary inflow, but not on veins even though venous disorders may initiate or exacerbate brain injury. In this commentary, we advance the term "recirculation" after "recanalization" and "reperfusion" as a primary concept of stroke pathophysiology that targets the restoration of both the arterial and venous cerebral circulations...

Cerebral venous sinus thrombosis(CVST)is a rare condition accounting for <1% of all strokes. It has been linked to a multitude of risk factors, including infections, oral contraceptive use, coronary disease, malignant disease, trauma, surgery, coagulopathy and several others. However, the association between hyperthyroidism and CVST is poorly understood. We describe here a rare case of CVST, secondary to subclinical Basedow disease. A 68-year-old woman with general fatigue, headache, speech disturbance and slow behavior was admitted to our hospital...

BACKGROUND: Maintaining brain oxygenation status is the main goal of treatment in severe traumatic brain injury (TBI). Jugular venous oxygen saturation (SjvO2) monitoring is a technique to estimate global balance between cerebral oxygen supply and its metabolic requirement. Full Outline of Responsiveness (FOUR) score, a new consciousness measurement scoring, is expected to become an alternative for Glasgow Coma Scale (GCS) in evaluating neurologic status of patients with severe traumatic head injury, especially for those under mechanical ventilation...

Cerebral venous thrombosis (CVT) is a rare and potentially life-threating cause of stroke. A number of etiologies and risk factors for CVT have been identified so far. These include head trauma, local and systemic infectious diseases, malignancies, autoimmune diseases, and oral contraceptive use. The most common clinical symptoms are headache and changes in consciousness. Cranial nerve palsy in CVT is uncommon, and there are very few reports of facial nerve palsy. This case report highlights an atypical manifestation in a CVT patient, who presented with peripheral facial palsy...

Cerebral air embolism (CAE) is a potentially fatal iatrogenic complication related to common procedures including central venous catheter (CVC) removal. We report an interesting case of CAE related to CVC removal that was further complicated with status epilepticus. Neuroimaging of CAE and status epilepticus could pose diagnostic dilemmas and require consideration of wide diagnostic differentials. We discuss the clinical presentation, mechanism, and diagnostic approach, especially neuroimaging to differentiate various etiologies in CAE patients...

Visual impairment can complicate cerebral venous thrombosis (CVT). Here, we describe the various pathophysiological mechanisms and treatments available. A retrospective chart review of all patients treated for CVT in a large quaternary teaching hospital was done, and cases with visual impairment due to CVT were identified. The various mechanisms causing visual impairment in CVT were (1) raised intracranial pressure (ICP) caused by venous thrombosis without venous infarcts resulting in a benign intracranial hypertension-like presentation of CVT, (2) venous infarcts involving the occipital cortex, (3) raised ICP following the development of a secondary dural arteriovenous (AV) fistula, and (4) arterial occipital infarcts due to posterior cerebral artery compression secondary to herniation in large venous infarcts...

Detailed molecular pathways for the specific growth of arteries and lymphatic vessels have been identified, but the mechanisms controlling venous vessel growth have been obscure. Tischfield and colleagues (2017) shed new light on this problem by identifying a role for BMP signaling in development of the cerebral venous system.

The systemic inflammatory response triggered by lipopolysaccharide (LPS) is associated with cerebral vasoconstriction, but the underlying mechanisms are unknown. We therefore examined whether a four-hour intravenous LPS infusion (0.3 ng kg<sup>-1</sup>) induces any changes in the transcerebral net exchange of the vasoactive peptides endothelin-1 (ET-1) and calcitonin-gene related peptide (CGRP) and catecholamines in human volunteers. Cerebral blood flow was measured by the Kety-Schmidt technique, and paired arterial-to-jugular venous blood samples were obtained for estimating the transcerebral exchange of ET-1, CGRP and catecholamines by the Fick principle in twelve volunteers before and after LPS...

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...

BACKGROUND: Stereotactic radiosurgery (SRS) is a well-established treatment modality for cerebral arterio-venous malformations (AVMs). The main limiting factor in the radiosurgical treatment of AVMs is the volume of the nidus with high-grade lesions often requiring combined treatment to reduce the SRS target volume. To overcome this limitation, we have been using a combined treatment approach consisting of endovascular embolization with ONYX followed by SRS. OBJECTIVE: To evaluate our clinical experience for safety and feasibility of this multimodality treatment approach...

BACKGROUND: Post-cardiac arrest (CA) patients admitted to the intensive care unit (ICU) have a poor prognosis, with estimated survival rates of around 30%-50%. On admission, these patients have a large cerebral penumbra at risk for additional damage in case of suboptimal brain oxygenation during their stay in the ICU. The aim of the Neuroprotect post-CA trial is to investigate whether forcing mean arterial blood pressure (MAP) and mixed venous oxygen saturation (SVO2) in a specific range (MAP 85-100 mm Hg, SVO2 65%-75%) with additional pharmacological support (goal-directed hemodynamic optimization) may better salvage the penumbra, reduce cerebral ischemia, and improve functional outcome when compared with current standard of care (MAP 65 mm Hg)...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) may be life-saving in several clinical situations, but it is also one of the most invasive therapeutic procedures, with significant potential for life-threatening complications. Pulse pressure waves are typically very small or even absent at the onset of ECMO therapy, and will reappear with the improvement of cardiac function. A low pulse pressure may indicate low cardiac output due to heart failure during sustained ECMO support...

Background Stroke risk is increased during pregnancy, but estimates of pregnancy-related stroke incidence vary widely. Aims A systematic review and meta-analysis was conducted to assess the incidence of stroke during pregnancy and the puerperium. Ovid Medline, EMBASE, and ISI Web of Science were searched for studies published between 1990 and January 2017 reporting stroke incidence during pregnancy and postpartum, from defined pregnancy populations. Pooled analyses were conducted using a random effects approach and expressed as an incidence rate per 100,000 pregnancies, with 95% confidence intervals...

Hyperhomocysteinemia can cause cerebral venous thrombosis. Recombinant tissue plasminogen activator is one of the treatment options for cerebral venous thrombosis in selected cases. We present here a 7-year-old boy with homocysteinuria with stroke. MRI of brain showed cerebral venous sinus thrombosis. We successfully treated with intravenous recombinant tissue plasminogen activator. He recovered completely without any complications. Recombinant tissue plasminogen activator can be considered one of the treatment options in cerebral venous thrombosis in homocystinura...

Thrombotic cardiovascular disease, including acute myocardial infarction, ischemic stroke, and venous thromboembolic disease, is the leading cause of morbidity and mortality worldwide. While reperfusion therapy with thrombolytic agents reduces mortality from acute myocardial infarction and disability from stroke, thrombolysis is generally less effective than mechanical reperfusion and is associated with fatal intra-cerebral hemorrhage in up to 2-4% of patients. To address these limitations, we propose the tobacco mosaic virus (TMV)-based platform technology for targeted delivery of thrombolytic therapies...

Retrievable inferior vena cava (IVC) filters are increasingly used in patients with venous thromboembolism (VTE) who have contraindications to anticoagulant therapy. However, previous studies have shown that many retrievable filters are left permanently in patients. This study aimed to identify the common indications for IVC filter insertion, the filter retrieval rate, and the predictive factors for filter retrieval attempts. To this end, a retrospective cohort study was performed at a tertiary care center in South Korea between January 2010 and May 2016...
