BACKGROUND: Carotid endarterectomy (CEA) is a beneficial procedure for selected patients with an internal carotid artery (ICA) stenosis. Surgical risk of CEA varies from between 2 and 15%. The aim of the study is to demonstrate the safety and effectiveness of sonolysis (continual transcranial Doppler monitoring, TCD) using a 2-MHz diagnostic probe with maximal diagnostic energy on the reduction of the incidence of stroke, transient ischemic attack (TIA) and brain infarction detected using magnetic resonance imaging (MRI) by the activation of the endogenous fibrinolytic system during CEA...

BACKGROUND AND AIMS: Vascular disease (VD), as assessed by history of myocardial infarction or peripheral artery disease or aortic plaque, increases stroke risk in atrial fibrillation (AF), and is a component of risk assessment using the CHA2DS2-VASc score. We investigated if systemic atherosclerosis as detected by ultrasound carotid plaque (CP) could improve the predictive value of the CHA2DS2-VASc score. METHODS: We analysed data from the ARAPACIS study, an observational study including 2027 Italian patients with non-valvular AF, in whom CP was detected using Doppler Ultrasonography...

The identification/selection of appropriate patient subgroups with asymptomatic carotid artery stenosis and the performance of prophylactic carotid endarterectomy (CEA)/carotid artery stenting (CAS) exclusively on these asymptomatic patient subgroups is currently one of the "hottest" topics in vascular surgery. It is now clear that offering CEA/CAS to asymptomatic carotid patients based only on the degree of carotid stenosis is unjustified and scientifically flawed. On the other hand, offering only best medical therapy to every asymptomatic patient, irrespective of certain high-risk criteria (such as the detection of microemboli by transcranial Doppler, intraplaque hemorrhage, silent embolic infarcts on brain computed tomography/magnetic resonance imaging, elevated biomarkers, family history), is equally wrong...

BACKGROUND AND PURPOSE: Symptomatic carotid artery disease is associated with significant morbidity and mortality. The pathophysiologic mechanisms of cerebral ischemia among patients with carotid occlusion remain underexplored. METHODS: We conducted a prospective observational cohort study of patients hospitalized within 7 days of ischemic stroke or transient ischemic attack because of ≥50% carotid artery stenosis or occlusion. Transcranial Doppler emboli detection was performed in the middle cerebral artery ipsilateral to the symptomatic carotid...

Thromboembolism prevention is a crucial factor determining both the natural outcome and outcome of intervention of stenotic atherosclerotic carotid artery pathology. Roughly 80% of all natural course cerebral ischemic events are caused by thromboembolism, versus 20% due to hemodynamic insufficiency. The risk of periprocedural cerebral (micro) thromboembolization during carotid revascularization is considered to be even higher, with a higher rate in carotid artery stenting (CAS) as compared to carotid endarterectomy (CEA)...

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...

Embolic Protection Devices (EPD's) are often used during Carotid Angioplasty and Stenting (CAS) to reduce procedural cerebral emboli. This manuscript seeks to present an overview of evidence on EPD's during CAS. There are three categories of EPD's: Distal Occlusion (DO-EPD), Filter (F-EPD) and Proximal Occlusion (PO-EPD). DO and F-EPD's have the disadvantage that the device has to be advanced through the stenosis, without protection and that the device may damage the distal internal carotid artery (ICA). F-EPD's have the advantage of maintaining antegrade flow throughout the procedure...

BACKGROUND: Stroke is a severe clinical disorder in sickle cell disease (SCD), and few studies have evaluated transcranial Doppler (TCD) flow velocities in hemoglobin SC disease (HbSC). The guidelines for stroke risk are based on evaluations in sickle cell anemia (SCA) or HbS/β thalassemia. PROCEDURE: In this study, we compare cerebral blood flow in patients with SCD stratified by genotypes. A total of 1,664 pediatric patients with SCD underwent TCD velocity screening, and the time-averaged maximum mean velocity (TAMM) was determined in the middle cerebral artery (MCA), anterior cerebral artery (ACA), and distal intracranial internal carotid artery (ICA) ...
