Carotid artery stenting (CAS) is considered an alternative option to carotid endarterectomy (CEA) for significant carotid stenosis, in both symptomatic and asymptomatic patients. Comparing to CEA, CAS offers significant advantages. The most important arise from the minimally invasive nature of the procedure, which reduces the surgical complications and adds significant comfort to the patient, without compromising the efficacy. Nowadays, CAS can achieve acute and long-term outcome results comparable to CEA, maintaining low rates of periprocedural embolic events...

Acute ischemic stroke (AIS) is the leading cause of premature mortality and morbidity worldwide for both men and women. Extracranial carotid artery stenosis/occlusion is responsible for approximately 11.5%% of ischemic strokes, whereas extracranial large vessel disease comprises roughly 16.6% of ischemic strokes. Carotid artery disease has been the source of significant debate among neurovascular and cardiovascular specialists, as well as vascular surgeons, as to the best method of revascularization, surgical reconstruction versus endovascular recanalization...

Graves disease is rarely complicated with cerebrovascular steno-occlusive diseases. Previous studies have suggested several hypotheses for this occurrence, including excess thyroid hormone, which stimulates the sympathetic nervous system, which in turn causes an abnormal hemodynamic response with consequent atherosclerotic changes, and antithyroid antibodies cause local vascular inflammation in patients with Graves disease. However, radiological findings of vasculitis in patients with Graves disease and cerebral infarction remain less known...

BACKGROUND: As a systemic disease, atherosclerosis commonly affects intracranial and extracranial carotid arteries simultaneously which is defined as co-existing plaques. Previous studies demonstrated that co-existing atherosclerotic diseases are significantly associated with ischemic cerebrovascular events. The aim of this study was to investigate the characteristics of co-existing intracranial and extracranial carotid atherosclerotic plaques and their relationships with recurrent stroke by using 3D multi-contrast magnetic resonance (MR) vessel wall imaging...

BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

Although stopping smoking, lowering blood pressure and reducing lipid levels will reduce global stroke risk and cardiovascular mortality, these remain leading causes of death and disability especially in ageing populations. Further prevention strategies are needed and, in the first part of this review, we explore the potential benefits of appropriate screening for carotid artery disease to reduce stroke and identify those who may have related cardiac disease. Although whole-population carotid screening is an inefficient and costly means of identifying candidates with tight carotid stenosis who might warrant intervention, it can identify many people with lower levels of stenosis who may benefit from cardiovascular risk reducing medications...

In the last few years, there has been a gradual shift in the recommendations of carotid guidelines towards performance of carotid endarterectomy (CEA) earlier in patients with >70% carotid artery stenosis suffering an ipsilateral transient ischemic attack (TIA)/minor stroke episode. The "6-month" threshold in the early guidelines was subsequently replaced with a "14-day" target. More recently, an even earlier intervention (i.e. "within 48 hours") gains support as the optimal timing for the performance of CEA in patients with symptomatic carotid artery stenosis...

BACKGROUND AND PURPOSE: Progression of asymptomatic carotid artery stenosis (ACAS) in patients with >50% luminal narrowing is considered a potential risk factor for ischemic stroke; however, subclinical molecular biomarkers of ACAS progression are lacking. Recent studies suggest a regulatory function for several microRNAs (miRNAs) on the evolution of carotid plaque, but its role in ACAS progression is mostly unknown. The aim of our study was to investigate a wide miRNA panel in peripheral blood exosomes from patients with ACAS to associate circulating miRNA expression profiles with stenosis progression...

Carotid artery stenosis (CS) is a major cause of ischemic stroke. Treatment of CS consists of best medical treatment and carotid revascularization (CR), including carotid endarterectomy (CEA) and carotid artery stenting (CAS). Both CR techniques have their own procedural risks. Therefore, selection of the appropriate treatment for patients with CS is relatively complicated. Many studies and guidelines have reported the efficacy of each treatment for both symptomatic and asymptomatic patients. However, the results are still controversial, especially concerning the efficacy and safety of CEA and CAS...

RATIONALE: In the search for markers and modulators of vascular disease, miRNAs have emerged as potent therapeutic targets. OBJECTIVE: To investigate miRNAs of clinical interest in patients with unstable carotid stenosis at risk of stroke. METHODS AND RESULTS: Utilizing patient material from the Biobank of Karolinska Endarterectomies (BiKE), we profiled miRNA expression in patients with stable vs unstable carotid plaque. A PCR-based miRNA array of plasma, sampled at the carotid lesion site, identified eight deregulated miRNAs (miR-15b, -29c, -30c/d, -150, -191, -210 and -500)...

OBJECTIVE: Because some cryptogenic strokes may result from large-artery atherosclerosis that goes unrecognized as it causes <50% luminal stenosis, we compared the prevalence of nonstenosing intracranial atherosclerotic plaques ipsilateral to cryptogenic cerebral infarcts versus the unaffected side using imaging biomarkers of calcium burden. METHODS: In a prospective stroke registry, we identified patients with cerebral infarction limited to the territory of one internal carotid artery (ICA)...
