OBJECTIVE: Chronic kidney disease (CKD) increases morbidity and mortality after vascular procedures and adversely affects late survival of patients. The presence of CKD also confers increased risk of stroke in patients with asymptomatic carotid stenosis. Patients undergoing carotid intervention in the Vascular Study Group of New England database were stratified by CKD status referable to periprocedural and late outcomes. METHODS: All carotid artery stenting and carotid endarterectomies (CEAs) performed from 2003 to 2013 were stratified by CKD severity as mild (estimated glomerular filtration rate [eGFR] >60 mL/min/1...

BACKGROUND: Blood pressure (BP) was reported to decrease significantly after carotid endarterectomy (CEA) or carotid stenting (CAS) up to the 1-year follow-up. We evaluated changes in BP for 3 years after treating hypertensive patients with symptomatic carotid artery stenosis by either CEA or CAS and determined predisposing factors for normotensive BP at the 3-year follow-up. METHODS: A total of 123 hypertensive patients with at least 3 years of clinical and radiographic follow-up after treatment were included in this study and placed in the CEA (n = 65) or CAS group (n = 58)...

Serum c-reactive protein (CRP) was suggested for the assessment of intermediate cardiovascular (CV) risk. Here, systemic or intraplaque CRP levels were investigated as predictors of major adverse cardiovascular events (MACEs) in patients with severe carotid stenosis. CRP levels were assessed in the serum and within different portions (upstream and downstream) of carotid plaques of 217 patients undergoing endarterectomy. The association between CRP and intraplaque lipids, collagen, neutrophils, smooth muscle cells (SMC), and macrophage subsets was determined...

AIMS: Rapid access carotid endarterectomy (RACE) is the gold standard for stroke prevention in symptomatic patients with 50-99% internal carotid artery stenosis. Diagnosis and referral of eligible patients may be delayed by disruption to local health services. The aim of this study was to evaluate whether service provision was maintained at an appropriate standard (<2 weeks) following a natural disaster. METHODS: Consecutive symptomatic patients who underwent carotid endarterectomy (CEA) at a tertiary hospital between January 2006 and December 2014 were identified...

BACKGROUND: Restenosis after carotid endarterectomy (CEA) is associated with an increased risk of stroke, and the management of critical or symptomatic restenotic lesions poses a treatment challenge. The superiority of CEA vs carotid angioplasty and stenting (CAS) for restenosis remains debatable because existing studies are few and limited by small sample size or the inability to align interventions with ipsilateral events beyond the periprocedural period. We performed a population-based evaluation of CEA vs CAS in a large contemporary cohort of patients with carotid artery restenosis...

Stroke imposes a substantial clinical and socioeconomic burden. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are proven procedures in stroke prevention for the lesions of extracranial carotid disease. Although several studies have addressed national trends regarding carotid revascularization in Western countries, limited data is available with respect to the Korean population. The aim of the present study was to identify the national trend in carotid revascularization in Korea over the previous decade...

BACKGROUND: Carotid endarterectomy (CEA) is the procedure of choice for reducing the risk of stroke in both symptomatic and asymptomatic carotid artery stenoses. Stroke is associated with significant morbidity and mortality peri-operatively (2-3 %). Our primary aim is to evaluate the etiology of these strokes after CEA and their impact on morbidity by comparing the length of stay in the hospital. METHODS: A total of 584 patients with documented neurological status evaluations who underwent CEAs were included in the study...

BACKGROUND: For optimal stroke prevention, best practices guidelines recommend carotid endarterectomy (CEA) for symptomatic patients within two weeks; however, 2013 Ontario data indicated that only 9% of eligible patients from outpatient Stroke Prevention Clinics (SPCs) achieved this target. The goal of our study was to identify modifiable system factors that could enhance the quality and timeliness of care among patients needing urgent CEA. METHODS: We conducted a retrospective chart review of transient ischemic attack/stroke patients assessed in Champlain Local Health Integrated Network SPCs between 2011 and 2014 who subsequently underwent CEA...

OBJECTIVES: In selected populations, carotid endarterectomy (CEA) reduces long-term stroke risk. Studies have shown increased risk of restenosis with use of a collagen-impregnated Dacron patch compared to a PTFE patch. There is concern that collagen-impregnation may initiate thrombosis or promote restenosis due to platelet activation. We performed a retrospective analysis of our CEA experience with routine patching using knitted Dacron patches with (Hemashield) and without (Sauvage) collagen-impregnation...

Acute internal carotid artery (ICA) occlusion may result in severe disability or death. Revascularization by carotid artery stenting after treatment with intravenous (iv) recombinant tissue-type plasminogen activator (rt-PA) has been documented. However, there are few reports on emergency carotid endarterectomy (CEA) within 24 hours after the iv administration of rt-PA. We treated a 58-year-old man with right ICA occlusion with iv rt-PA. Although partial recanalization of the ICA was obtained, severe stenosis at the origin of the ICA persisted and he developed fluctuating neurological deficits...

Purpose. To investigate the alternation in cerebral and ocular blood flow velocity (BFV) in patients of carotid stenosis (CS) with or without contralateral carotid occlusion (CO) early after carotid endarterectomy (CEA). Patients and Methods. Nineteen patients underwent CEA for ≥50% CS. Fourteen patients had the unilateral CS, and five patients had the ipsilateral CS and the contralateral CO. Transcranial Doppler (TCD) and Color Doppler Imaging (CDI) were performed before and early after CEA. Results. In patients with unilateral CS, significant improvements in BFV were observed in anterior cerebral artery (ACA) and middle cerebral artery (MCA) on the ipsilateral side after CEA...

BACKGROUND AND PURPOSE: The indications for carotid endarterectomy (CEA) and carotid artery stenting (CAS) have not been established. CEA is more appropriate than CAS if soft atherosclerotic plaques are included in the stenotic lesion, since such soft plaques are associated with a high incidence of ischemic complications during CAS. This report presents our surgical methods and the clinical results of CEA and CAS, and suggests an appropriate treatment strategy using plaque diagnosis, especially for high-risk patients...

Data from randomized controlled trials (RCTs) demonstrated significant differences between carotid artery stenting (CAS) and carotid endarterectomy (CEA) in terms of early neurological outcomes (from 0 to 30 days), although mid- and long-term neurological results are indistinguishable. CAS in symptomatic standard risk patients is coupled with a higher risk of any stroke, and death or any stroke at 30 days, while the rates of disabling or major stroke do not vary remarkably between treatments. Since the micro-embolization through the stent struts is the primary suspected cause of suspected early postoperative neurological complications (i...

BACKGROUND: Carotid endarterectomy remains the most effective surgical treatment for reducing the risk of stroke in patients with significant carotid stenosis. In fact, endovascular approach is associated with a higher incidence of perioperative and long-term minor stroke when compared to carotid endarterectomy although long-term functional outcome and risk of major stroke are similar. However, advanced age resulted to be associated with an increased risk of complications after carotid endarterectomy...
