BACKGROUND: Carotid stent fractures are rare and multiple etiologies have been proposed to explain their occurrence. We present a patient with a internal carotid artery (ICA) stent who developed in-stent restenosis. We performed balloon angioplasty to address in-stent restenosis but post-procedure he developed a carotid stent fracture. To our knowledge, balloon angioplasty has not been reported to cause stent fractures and we report the first case report. CASE DESCRIPTION: 72-year-old male underwent stenting for symptomatic left ICA stenosis with post-stenting residual stenosis of 55%...

OBJECTIVE: In-stent restenosis is a recognized complication of carotid angioplasty and stenting (CAS), and it is associated with an increased risk of stroke. Few case series have reported outcomes separately following carotid endarterectomy (CEA) and CAS for the treatment of in-stent restenosis. In this study, we perform an evaluation of redo-CAS vs CEA in a large contemporary cohort of patients who underwent prior ipsilateral CAS. METHODS: We studied all patients in the Vascular Quality Initiative (VQI) database, who underwent CEA or CAS between January 1, 2003, and April 30, 2016, after prior ipsilateral CAS...

Our aim was to report techniques and our experience in One-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. An 81-year-old man presented with a transient ischemic attack. Neurologic examination showed left side transient visual obscuration or amaurosis fugax and right hemiparesis. Carotid duplex imaging revealed an 80% stenosis of the left internal carotid artery (LICA) and 95 % of the ostium of left common carotid artery (left CCA)...

OBJECTIVE: Excelsior XT-27 (Stryker Neurovascular, Fremont, CA, USA) or Rebar 27 (eV3 Covidien, Irvine, CA, USA) microcatheters have recently been used to overcome the limitations of the Renegade Hi-Flo microcatheter such as interference between two microcatheters (one for stent delivery and the other for cerebral aneurysm coiling) during the jailing technique. We evaluated differences and influential factors related to the interference phenomenon according to these two microcatheters group...

BACKGROUND: Whereas in-stent restenosis (ISR) is widely discussed after coronary stenting procedures, this phenomenon is a considerable problem after interventional treatment of carotid artery stenosis as well. We sought to quantify ISR rate and to identify important respective risk factors in our cohort. METHODS: We retrospectively analyzed data of our carotid artery stenting database comprising 1165 angiographically successful interventional procedures during the last 19 years...

BACKGROUND: -Remote ischemic preconditioning (RIPC) can inhibit recurrent ischemic events effectively in patients with acute or chronic cerebral ischemia. However, it is still unclear that whether RIPC can impede ischemic injury after carotid artery stenting (CAS) in patients with severe carotid artery stenosis. METHODS: -Subjects with severe carotid artery stenosis were recruited in this randomized controlled study, and assigned to RIPC, sham and no intervention (control) groups...

Large pseudoaneurysms which compress the parent vessel are challenging lesions to successfully treat with endovascular therapy. We describe the endovascular treatment of a giant extracranial carotid artery (ECCA) pseudoaneurysm resulting in substantial mass effect on the common carotid artery (CCA) bifurcation using a telescoping dual covered stent graft construct. A 56-year-old male was diagnosed with an 8.5 cm × 13 cm pseudoaneurysm arising from the left CCA bifurcation, which was causing luminal narrowing of the CCA and proximal internal carotid artery (ICA)...

We hereby report a novel technical approach for the treatment of acute stroke with underlying tandem occlusion. The so-called retriever wire supported carotid artery revascularization (ReWiSed CARe) technique, utilizing the wire of a stent-retriever as a guiding wire for carotid artery stenting, is technically feasible in tandem occlusions caused by an internal carotid artery (ICA) dissection or high grade ICA stenosis. This technique eliminates the need to use a long microwire in order to maintain the position inside the true lumen of a dissection...

PURPOSE OF REVIEW: Extracranial or intracranial large artery atherosclerosis is often identified as a potential etiologic cause for ischemic stroke and transient ischemic attack. Given the high prevalence of large artery atherosclerosis in the general population, determining whether an identified atherosclerotic lesion is truly the cause of a patient's symptomatology can be difficult. In all cases, optimally treating each patient to minimize future stroke risk is paramount. Extracranial or intracranial large artery atherosclerosis can be broadly compartmentalized into four distinct clinical scenarios based upon the individual patient's history, examination, and anatomic imaging findings: asymptomatic and symptomatic extracranial carotid stenosis, intracranial atherosclerosis, and extracranial vertebral artery atherosclerotic disease...

A significant controversy exists regarding the clinical impact of hemodynamic depression on major adverse events after carotid artery stenting (CAS). The purpose of this study was to evaluate the incidence, predictors, and clinical significance of hypotension after CAS. A total of 118 cases of carotid artery stenosis were treated with CAS. Hypotension was defined as sustained systolic blood pressure <80 mmHg and requiring intravenous administration of vasopressor to maintain adequate systolic blood pressure after the procedure...

BACKGROUND: Although aortic stiffness assessed by pulse wave velocity (PWV) is a strong predictor of coronary artery disease, the significance of local coronary stiffness has never been tackled. The first objective of this study was to describe a method of measuring coronary PWV (CoPWV) invasively and to describe its determinants. The second objective was to assess both CoPWV and aortic PWV in patients presenting with acute coronary syndromes or stable coronary artery disease. METHODS AND RESULTS: In 53 patients, CoPWV was measured from the delay in pressure wave and distance traveled as a pressure wire was withdrawn from the distal to the proximal coronary segment...

Extracranial internal carotid artery atherosclerotic occlusive disease is a common ischemic stroke mechanism. Vascular risk factor control remains the cornerstone of stroke prevention in patients with both asymptomatic and symptomatic carotid occlusive diseases. Intensive medical therapy refers to the contemporary approach of antiplatelet therapy, blood pressure control, low-density lipoprotein reduction, and lifestyle modification to reduce stroke risk. Carotid revascularization with endarterectomy or angioplasty and stenting are established treatments for patients with symptomatic carotid stenosis ≥70%...

Objective The aim of this study was to construct an in vivo carotid siphon model for testing neurovascular devices for endovascular interventions. Methods A model of a human carotid siphon was pre-shaped using a glass tube from a human cadaver and used to confine a segment of one side of the common carotid artery (CCA) in canines. This segment of CCA with the glass carotid siphon on was interposed end-to-end onto the contralateral CCA so as to simulate a human carotid artery siphon in vivo. Two weeks later, the siphon model was evaluated using computed tomography angiography and digital subtraction angiography, and the covered stent specially designed for intracranial vasculature was navigated through the siphon model for a longitudinal flexibility test...
