Surgical Treatment for Carotid Stenoses with Highly Calcified Plaques
Background: The aim of this study was to clarify both the present status of treatment for carotid stenosis with highly calcified plaques and the appropriate treatment.Methods: A total of 140 consecutive treatments for carotid stenoses (carotid endarterectomy [CEA]:carotid artery stenting [CAS] 81:59) were enrolled in the study. We classified the patients into low-calcified plaque (LCP) and high-calcified plaque (HCP) groups by calcium score, determined by a receiver operating characteristic analysis, and we compared the results after both treatments.Results: The mean degree of residual stenosis and improvement rates of the...

Neurologic and Functional Long-term Outcome after Carotid Endarterectomy
Background: The aim of this research was to assess the neurologic status of patients a year after endarterectomy with the use of National Institutes of Health Stroke Scale (NIHSS) and the degree of disability using the modified Rankin Scale (mRS) and to examine the patients' subjective evaluation of their health.Methods: One hundred two patients with symptomatic internal carotid artery stenosis who underwent endarterectomy and attended a 1-year follow-up examination were enrolled in the study. The material comprised 72 (70.6%) men and 30 (29.4%) women. Before the surgery, the patients' neurologic status was assessed accord...

Predictors and Consequences of Silent Brain Infarction in Patients with Asymptomatic Carotid Stenosis
Silent brain infarction (SBI) is associated with an increased risk of stroke in patients with asymptomatic carotid stenosis (ACS), and is therefore one of the criteria for performing carotid endarterectomy (CEA). Despite an extensive literature, this issue is still a matter of debate. Aim of the present work was to evaluate incidence and predictors of SBI in patients undergoing CEA for ACS, and to investigate its possible impact on CEA outcome.

Carotid Endarterectomy Using Lone Star Retractor System
As you know, atherosclerosis is a serious public problem and is the leading cause of morbidity and mortality not only in western countries but also in Asia. Cervical carotid disease is typical atherosclerosis, which is responsible for ischemic stroke. The effectiveness of carotid endarterectomy (CEA) for advanced carotid stenosis has been established in many large studies,1 –3 and CEA is the gold standard in surgical treatment. On the other hand, endovascular carotid artery stenting (CAS) has become increasingly popular recently.

Immunohistochemical analysis of MMP-9 and COX-2 expression in carotid atherosclerotic plaques among patients undergoing carotid endarterectomy: A prospective study
Atherosclerotic disease of the internal carotid artery is the most common cause of ischemic stroke making it the second commonest cause of death; therefore, the benefit of carotid endarterectomy (CEA) in both symptomatic and asymptomatic patients has been demonstrated by several randomized trials.1-3 Several studies highlighted that carotid atherosclerotic plaque remodelling can be partially mediated by matrix metalloproteinases (MMPs).4-7 Increased activity of MMPs can contribute to the degradation of collagen within the fibrous cap, making the cap thinner, more vulnerable and prone to rupture.

Complications and outcomes of carotid artery stenting in high-risk cases
In treatment of internal carotid artery stenosis, carotid artery stenting (CAS) is the standard choice for patients at risk for carotid endarterectomy (CEA). Occasionally, patients at risk of both CEA and CAS are encountered. In addition, in practice sometimes CAS is performed in patients with high risk due to patient preference and other factors. In general, symptomatic carotid artery stenosis is a risk factor for CAS1. Despite this, the American Heart Association and Stroke Association guidelines recommend CAS as an alternative to CEA for symptomatic moderate-to-severe stenosis2.

Clinical, Anatomic, and Procedural Durability of Carotid Revascularization
Carotid endarterectomy and carotid angioplasty with stenting are 2 common approaches to revascularization. Phase III randomized clinical trials have focused on comparisons of periprocedural outcomes and composite outcomes that combine procedural events and clinical events during follow-up. The comparison of outcomes beyond the perioperative risk period, where the principal concern is durability, defined in clinical, anatomic, and procedural terms, has received less attention. The purpose of this review is to discuss factors that may influence durability and to compare the durability of carotid revascularization techniques...

The Effect of Carotid Endarterectomy on Cerebral Blood Flow and Cognitive Function
This study aims to characterize changes in cerebral blood flow after carotid endarterectomy and to determine if patients with improvement in cerebral blood flow have improved cognitive function after endarterectomy.Methods: Cerebral blood flow was measured preoperatively and 1 month postoperatively using phase contrast magnetic resonance angiography. Preoperative flow impairment was defined as ipsilateral flow at least 20% less than contralateral flow. Improvement in flow was defined as an absolute increase of at least 0.10 in flow ratio from pre- to postoperative assessments. Patients underwent cognitive testing preoperat...

Measurement of Carotid Stenosis Using Duplex Ultrasonography with a Microconvex Array Transducer: A Validation with Cerebral Angiography
Background: We aimed to evaluate the validity of duplex ultrasonography (DUS) using a microconvex array transducer (MAT) with enhanced flow imaging (EFI) for visualization of the distal, internal carotid artery (ICA) and the accurate assessment of ICA stenosis.Methods: Patients who underwent both DUS and digital subtraction angiography (DSA) were registered for this study. DUS was performed by using a linear array transducer (LAT) and an MAT with EFI. The visibility of the ICA was compared between the 2 transducers. ICA stenosis was evaluated by the North American Symptomatic Carotid Endarterectomy Trial (NASCET) method on...

Signal Intensity Changes for the Middle Cerebral Artery on 3-Dimensional Time-of-flight Magnetic Resonance Angiography Indicate Acute Hemodynamic Changes after Carotid Endarterectomy
In this study, we aimed to evaluate whether 3D-TOF-MRA could be used as an alternative to single-photon emission computed tomography (SPECT) for assessing the increase in the regional cerebral blood flow (rCBF) after carotid endarterectomy (CEA). To do this, we compared the SI of the middle cerebral artery (MCA) on magnetic resonance angiography (MRA) and the rCBF on SPECT.Methods: We enrolled 30 patients with internal carotid artery stenosis. SPECT and MRA were performed before and 3-4 days after CEA. rCBF was assessed using SPECT, and the SI of the MCA was assessed using single-slab 3D-TOF-MRA. Regions of interest were...

Effects of Carotid Endarterectomy or Stenting on Arterial Diameters in the Circle of Willis
Conclusions: Carotid revascularization improves anterior collateralization and reduces reliance on posterior collateral pathways via the CoW. Carotid stenting and endarterectomy appear to have different early effects on collateralization.
