Increased von Willebrand factor (VWF) and reduced ADAMTS13 activity are associated with arterial thrombosis. This may also be the culprit mechanism implicated in delayed cerebral ischaemia after aneurysmal subarachnoid haemorrhage (SAH). It was our objective to determine plasma VWF and ADAMTS13 in patients with SAH and healthy subjects; and to explore the levels of those markers and outcome after SAH. Forty consecutive patients were enrolled between September 2007 and April 2014 in a pilot study. Plasma samples were collected from SAH patients on post-bleed day (PBD) 0, 1, 3, 5, 7 and 10 and healthy controls...

Identifying the site of vascular bleeding in fatal cases of traumatic basal subarachnoid hemorrhage (TBSAH) is important, but can be very difficult to achieve when there is extensive blood clot in the posterior cranial fossa. Post mortem angiography in these circumstances has been reported previously but with mixed results, and is rarely used in current practice within the United Kingdom. We have developed a simple and effective post mortem angiography method, using fluoroscopy and clear modern contrast medium, suitable for use in the autopsy room...

PURPOSE: Pediatric cerebral sinovenous thrombosis (CSVT) is an important, though less common subtype of pediatric stroke. It has been linked to several risk factors, including cranial procedures, with few studies highlighting this relationship. The aim of this study was to characterize the diagnosis and treatment of CSVT after cranial surgery. METHODS: An institutional pediatric stroke research database was used to identify all CSVT cases diagnosed within 30 days of cranial surgery from November 2004 to December 2014...

Deep medullary veins drain into subependymal veins with four convergence zones and show parallel distribution patterns adjacent to the body or inferior horn and a radial pattern in the frontal horn or trigon of the lateral ventricle. As white matter imaging develops such as diffusion tensor imaging or susceptibility-weighted imaging, requirements for understanding of white matter structures are increasing, not only for understanding of neuronal tracts but also for that of other structures including the fine anatomy of white matter vessels...

Patients with chronic kidney disease (CKD) have an increased risk of vascular disease, which is associated with considerable health care costs. Vascular disease in CKD differs clinically and pathobiologically from that in patients with normal renal function. Besides the traditional risk factors, retention of uremic toxins contributes to the pathogenesis of vascular disease in patients with CKD. Indoxyl sulfate is a protein-bound uremic toxin and is inefficiently removed by conventional dialysis. Accumulating evidence suggests that indoxyl sulfate is a vascular toxin involved in atherosclerosis, arteriosclerosis, vascular calcification and vascular repair...

BACKGROUND AND OBJECTIVES: The relative bleeding risk of aspirin versus vitamin K antagonists (VKA) is unclear. Most of previous meta-analyses included trials with target INR for VKA therapy far beyond usually recommended range (2-3). The aim of this study was to compare the bleeding risk of aspirin and VKA, as indicated by the aggregate body of clinical evidence including data from the recently published WARCEF trial. METHODS: In this meta-analysis we included randomized controlled trials that compared aspirin to VKA (1...

Posterior reversible encephalopathy syndrome (PRES) and cerebral sinus thrombosis are 2 known complications of acute lymphoblastic leukemia and its treatment. We describe a patient with acute lymphoblastic leukemia whose course was complicated by both of these conditions. This case is novel both for the fact that PRES developed before the initiation of therapy and that PRES was followed shortly by the development of cerebral sinus thrombosis. Our patient's story raises questions about our current understanding of the pathophysiology of PRES, and it suggests that PRES may actually be a predisposing risk factor for cerebral sinus thrombosis...

AIMS: To date every post-procedural cerebrovascular embolic event (CVE) is dreaded for its potential to accelerate cognitive decline after transcatheter aortic valve implantation (TAVI). This study differentiates the impact of acute (procedural) and post-acute cerebrovascular embolic events (CVEs) on cognitive performance. METHODS: Magnetic resonance imaging (MRI) before, early and late after TAVI was performed to quantify embolic burden. Quantification of diffusion- and T1-weighted lesions, as well as white-matter and total brain volumes, as well as cognitive function testing (MMSE) were assessed in 28 patients with a medium follow-up period of 34 months...

Biobanking of atherosclerotic tissue samples has contributed to our understanding of vascular occlusive disease. The careful examination of atherosclerotic plaques derived during vascular surgery or autopsies helped shape our minds in understanding the underlying substrate of arterial thrombosis. This review will outline concepts of progression of atherosclerotic disease that have been based on descriptions of human plaque pathology. In addition, we will discuss the current shift in clinical presentation and underlying pathology of acute cerebral and coronary events that asks for a careful consideration of the currently widely applied description of the "vulnerable plaque"...

The antiphospholipid syndrome (APS) is an acquired autoimmune thrombophilic disorder that is characterized by thrombosis (venous, arterial and microvascular) and obstetric morbidity due to a diverse family of antibodies against phospholipid-binding proteins present in plasma. The term antiphospholipid antibody is actually a misnomer as the antibodies are not against the phospholipid per se, but target the plasma protein co-factors, which bind to anionic PLs. The exact etiology has not been elucidated and is multifactorial...

BACKGROUND: The diagnosis of cerebral venous sinus thrombosis still remains a real challenge. Seizure, unusual headache with sudden onset, unexplained persistently unilateral vascular headache and neurologic deficit-which is difficult to be attributed to a vascular territory are some of the suggestive symptoms. CASE: An isolated sixth nerve palsy is discussed as a rare presentation for cerebral venous thrombosis. Following the extensive investigation to rule out other possible diagnoses, magnetic resonance venogram revealed the final etiology of sixth nerve palsy that was ipsilateral left transverse sinus thrombosis; therefore, anticoagulant treatment with low molecular weight heparin was administered...

BACKGROUND AND OBJECTIVE: High altitude may be a factor associated with cerebral venous thrombosis (CVT). As our knowledge of CVT at high altitude is limited, it was decided to pool such information from the available case studies to determine whether high altitude can predispose to CVT. METHODS: A systematic review of the literature was performed for cases reporting CVT at high altitude. Searches of the PubMed database (up to July 2016) were performed for publications, using 'cerebral venous thrombosis' and 'high altitude' as keywords...

Factor XI (FXI) is an integral component of the intrinsic pathway of the coagulation cascade and plays a critical role in thrombus formation. Since its role in the pathogenesis of cerebral microembolic signals (MES) is unclear, this study utilized a potent and selective small molecule inhibitor of FXIa, Compound 1, to assess the effect of FXI blockade in our recently established preclinical model of cerebral MES induced by FeCl3 injury of the carotid artery in male New Zealand White rabbits. Ascending doses of Compound 1 were evaluated simultaneously for both carotid arterial thrombosis by a Doppler flowmeter and MES in the middle cerebral artery by a transcranial Doppler...

Coagulation Factor XII (FXII) plays a critical role in thrombosis. What is unclear is the level of enzyme occupancy of FXIIa needed for efficacy, and impact of FXIIa inhibition on cerebral embolism. A selective FXIIa inhibitor, recombinant human albumin-tagged mutant Infestin4 (rHA-Mut-inf), was generated to address these questions. rHA-Mut-inf displayed potency comparable to the original wild-type HA-Infestin4 (rHA-WT-inf) (human FXIIa KI = 0.07 and 0.12 nM, respectively), with markedly improved selectivity against FXa and plasmin...
