Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are the 2 current standard treatments for carotid artery stenosis. There is still no well-defined consensus with regard to their superiority. However, the minimally invasive nature of endovascular treatment makes CAS increasingly popular among vascular surgeons.
We hypothesized the inflammatory markers (IM) could be independent predictors of carotid stenosis progression (CSP) after carotid artery stenting (CAS).
Stroke is a major cause of morbidity or mortality after lung surgery. CAS is useful for detecting carotid artery stenosis, which is one of the causes of stroke. To investigate the frequency of, and risk factors for, preoperative carotid artery stenosis and to determine whether ultrasonographic carotid artery screening (CAS) contributes to preventing postoperative stroke or cardiovascular comorbidities in lung cancer patients.
Kawasaki disease (KD) is an acute systemic vasculitis that primarily affects the coronary artery, but does not commonly affect the carotid artery. Cerebral infarction (CI) with internal carotid artery stenosis (ICS) in patients with KD had never been reported. We report a patient with CI as a remote phase complication of KD.
Our purpose was to evaluate the clinical indications for carotid duplex ultrasonography and determine for each indication how often carotid artery disease was identified.We retrospectively reviewed the consecutive reports for 3191 carotid ultrasound examinations. We tracked 14 indications to determine how often examinations were requested for each indication and correlated each indication with the finding of carotid artery disease.We found 26.5% of all examinations were abnormal; 17.5% of patients showed in...
Carotid artery endarterectomy (CEA) remains the most common surgical intervention for the treatment of symptomatic and asymptomatic carotid artery stenosis. Several studies have shown a lower risk of periprocedural adverse events in statin-users who undergo coronary interventions orcarotid artery stenting.
A meta-analysis found that for internal carotid artery stenosis procedures in elderly patient, the risk of perioperative stroke is significantly higher for carotid artery stenting (CAS) than for carotid endarterectomy (CEA). We retrospectively examined characteristics and perioperative results of CAS for 80 years and over at a single medical center.
Increased platelet count and reticulated platelets in recently symptomatic versus asymptomatic carotid artery stenosis and in cerebral microembolic signal-negative patient subgroups: results from the HaEmostasis In carotid STenosis (HEIST) study.
The pathophysiological mechanisms responsible for the disparity in stroke risk between asymptomatic and symptomatic carotid stenosis patients are not fully understood. The functionally important reticulated platelet fraction and reticulocytes could play a role.
The present multi-center retrospective study aimed to compare the outcome of carotid artery stenting (CAS) versus carotid endarterectomy (CEA) among Korean patients with symptomatic extracranial carotid stenosis.
To investigate the relationship between cerebral vasomotor reactivity (VMR) and acute stroke in patients with internal carotid artery stenosis.
Using angled fenestrated clips for posteromedially projecting internal carotid artery (ICA) aneurysms may allow the surgeon to simultaneously obliterate the aneurysmal neck and preserve the branching artery by applying the blade of the clip parallel to the ICA. However, using these clips when the aneurysm neck involves the branching artery may have a risk of branching artery stenosis, occlusion, or incomplete obliteration of the aneurysm.
To study the effects of intermittent whole-body hypoxic preconditioning on patients with carotid artery stenosis.
Right-sided subclavian artery stenosis is a rare cerebrovascular disease involving the upper extremities. Considering an endovascular approach for its management requires increased endovascular and catheterization skills, when compared to the left side, due to the close approximation of the right subclavian artery origin, vertebral and common carotid arteries.
Background/aim: Our aim was to interpret the effects of deep neck space abscesses on the adjacent carotid artery according to abscess location, as well as to determine narrowing by calculating the mean stenosis ratios.Materials and methods: Neck computed tomography scans and clinical data of 45 children with neck abscesses were evaluated retrospectively for abscess location and internal carotid artery narrowing. The lumen areas of the carotid arteries were measured from standard levels, and stenosis ratios ...
OBJECTIVE Intracranial hemorrhage (ICH) associated with cerebral hyperperfusion syndrome is a rare but major complication of carotid artery revascularization. The objective of this study was to compare the rate of ICH after carotid artery stenting (CAS) with that after endarterectomy (CEA). METHODS The authors performed a retrospective population-based cohort study of patients who underwent carotid artery revascularization in the province of Ontario, Canada, between 2002 and 2015. The primary outcome was th...
The Dutch Audit for Carotid Interventions (DACI) registers all patients undergoing interventions for carotid artery stenosis in the Netherlands. This study describes the design of the DACI and results of patients with a symptomatic stenosis undergoing carotid endarterectomy (CEA). It aimed to evaluate variation between hospitals in process of care and (adjusted) outcomes, as well as predictors of major stroke/death after CEA.
A 78-year-old man presented with severe symptomatic aortic stenosis and a heavily calcified, stenotic aortic valve. Given multiple comorbidities, the heart team agreed on a transcatheter approach via the left common carotid artery.
Assessment of the Cerebral Hemodynamic Benefits of Carotid Artery Stenting for Patients with Preoperative Hemodynamic Impairment Using Cerebral Single Photon Emission Computed Tomography (SPECT) and Carbon Dioxide Inhalation.
BACKGROUND The aim of this study was to evaluate the effects of carotid artery angioplasty and carotid artery stenting (CAS) on cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in patients with preoperative cerebrovascular hemodynamic impairment. MATERIAL AND METHODS Seventeen patients with unilateral severe internal carotid artery (ICA) stenosis and ipsilateral CVR impairment underwent CAS. CBF and CVR were measured by single photon emission computed tomography (SPECT) with inhalation of carb...
Catheter-based intravascular near-infrared spectroscopy (NIRS) detects a lipid signal from atherosclerotic plaque. The aim of this study was to describe the effect of carotid artery stenting (CAS) on the lipid signal in a carotid stenosis.
Atherosclerosis of the internal carotid artery is an important cause of disabling ischemic stroke and therefore constitutes a major medical, social, and economic issue. Although advances in vascular imaging modalities during the last decades allow to risk stratify patients not solely on the degree of carotid artery stenosis but also based on 'high risk' features, there still remains a controversy over patient selection for carotid artery revascularization. Among other features of plaque vulnerability, there...
The effects and safety of transradial access for stenting of carotid artery stenosis in patients with bovine-type and type III aortic arch are currently unknown and are the purpose of this study.
Vascular and osteological parameters, such as the heights of the carotid bifurcation and distal end of the plaque, are important preoperative considerations for patients undergoing carotid stenosis procedures such as carotid endarterectomy. However, for patients with contrast contraindications such as allergies or nephropathies, three-dimensional computed tomography angiography (3D-CTA) is unavailable, and preoperative evaluation remains challenging. In the present study, we aimed to develop a preoperative ...
Carotid artery (CCA) dilation occurs in healthy subjects during cold pressor test (CPT), whilst the magnitude of dilation relates to cardiovascular risk. To further explore this phenomena and mechanism, we examined carotid artery responses to different sympathetic tests, with and without α-receptor blockade, and assessed similarity to these responses between carotid and coronary arteries.
The dynamic displacement of the carotid arteries with interference of the hyoid bone during swallowing, named as "flip-flop" phenomenon (FFP), may be associated with ischemic stroke. However, the extent to which FFP is prevalent in carotid artery disease remains unknown. We aimed to investigate its exact prevalence to explore the relationship between FFP and carotid artery disease.
