Increased Leucocyte-Platelet Complex Formation in Recently Symptomatic versus Asymptomatic Carotid Stenosis Patients and in Micro-emboli Negative Subgroups.
CONCLUSION: These data add to the evidence that leucocyte-platelet complex formation/platelet activation is increased in recently symptomatic versus asymptomatic patients, and may contribute to the pathogenesis of first and subsequent strokes in carotid stenosis patients, including those who are MES negative.

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves. Introduction Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

von Willebrand Factor Antigen, von Willebrand Factor Propeptide, and ADAMTS13 in Carotid Stenosis and Their Relationship with Cerebral Microemboli.
DISCUSSION:  VWF:Ag expression, a marker of endothelial ± platelet activation, is enhanced in recently symptomatic versus asymptomatic carotid stenosis patients, including in MES-ve patients, and decreases with ADAMTS13 activity over time following atherosclerotic TIA/ischemic stroke.

Anticoagulant management by low-dose of low molecular weight heparin in patients with nonvalvular atrial fibrillation following hemorrhagic transformation and complicated with venous thrombosis: Five case reports and literature review
For patients with nonvalvular atrial fibrillation (NVAF) following hemorrhagic infarction (HI)/hemorrhage transformation (HT) and complicated with venous thrombosis, the management of anticoagulation is controversial. Our study intends to explore the safety and effectiveness of using low-dose of low molecular weight heparin (LMWH) to treat NVAF patients with HI (or HT) and complicated with venous thrombosis. Between January 2018 and January 2019, NVAF related acute ischemic stroke patients with HT/HI, hospitalized in the department of neurology or rehabilitation in our hospital, are enrolled retrospectively. Among them,...

Relevance of Carotid Reocclusion in Tandem Lesions
CONCLUSIONS: CRO has a relevant clinical impact in our study, associating lower rates of good functional outcomes at 3 months. Independent factors of CRO were the recanalization degree, presence of pial collateral circulation, use of a stent as a protective factor, and use of general anesthesia during thrombectomy.PMID:35989291 | DOI:10.5551/jat.63560

Increased platelet activation in early symptomatic vs. asymptomatic carotid stenosis and relationship with microembolic status: results from the Platelets and Carotid Stenosis Study
DiscussionRecently, symptomatic carotid stenosis patients have had higher platelet counts (potentially reflecting increased platelet production, mobilization or reduced clearance) and platelet activation status than asymptomatic patients. MES were more frequently detected in early symptomatic than asymptomatic patients, but the differences between late symptomatic and asymptomatic groups were not significant. Increased lymphocyte‐platelet complex formation in recently symptomatic vs. asymptomatic MES‐negative patients indicates enhanced platelet activation in this early symptomatic subgroup. Platelet biomarkers, in com...

Carotid endarterectomy for symptomatic low-grade carotid stenosis
Conclusions: This study shows that CEA is a safe, effective, and durable treatment for patients with symptomatic low-grade carotid stenosis associated with unstable plaque. Patients had excellent protection against further ischemic events and survived long enough to justify the initial surgical risk. Plaque instability seems to play a major part in the onset of ischemic events, regardless the entity of lumen narrowing.

E-006 Familial Incidence of the Congenital Torcular Dural Arteriovenous Shunt
Purpose There are several hereditary disorders that are well known to be associated with arteriovenous malformations (AVMs) involving the central nervous system including Sturge-Weber, Klippel-Trenaunay-Weber, and Parkes-Weber syndromes as well as hereditary haemorrhagic telangiectasia and hereditary neurocutaneous angiomatosis. Furthermore, familial incidence of AVMs in the absence of congenital hereditary disorders also has been reported. Herein, we describe the occurrence of the giant torcular herophili (TH) dural arteriovenous fistula (AVF) in two pediatric cousins treated with endovascular embolization. Case report C...

Sonothrombolysis.
Authors: Meairs S Abstract Ultrasound (US) applied as an adjunct to thrombolytic therapy improves the recanalization of occluded vessels, and microbubbles can amplify this effect. New data suggests that the combination of US and microbubbles without tissue plasminogen activator may achieve recanalization with a lower risk of hemorrhage. Further possibilities include specific targeting of thrombus with immunobubbles as well as local drug delivery with US-sensitive liposomes. Clinical studies support the use of US for ischemic stroke therapy, and the first trials of enhancing sonothrombolysis with microbubbles have b...

Atrial Septal Defects and Cardioembolic Strokes
Atrial septal defects (ASDs) can be complicated by cardioembolic strokes, but the exact incidence is unknown. Patients with large and small shunts may present with a cardioembolic stroke. Patients with cryptogenic strokes should have cardiac ultrasound to see if an ASD is present. Cardioembolic strokes associated with ASD principally occur with 2 mechanisms. The first is paradoxic embolism involving a venous-based source of thrombus, which may subsequently pass through the ASD by right-to-left shunting, causing a cardioembolic stroke. The second is atrial fibrillation that can complicate the course of patients with ASDs, e...
