It is relatively difficult to treat restenosis when restenosis occurs following carotid artery stenting. Endarterectomy with simultaneous stent removal is an effective approach when restenosis occurs. The treatment method is still not well known. The present paper reports a case of restenosis after stenting that was treated with endarterectomy with a satisfactory treatment outcome. The patient, a 74-year-old male, underwent stenting 10 months before he was re-hospitalized. He seemed to recover well after stenting until one month before he was re-hospitalized, when he presented symptoms of cerebral ischemia...

BACKGROUND: Multiple dissections rarely occur with ruptured vertebral artery dissecting aneurysms (VADAs). Here, we report three cases of ruptured VADA concurrent with spontaneous cervical internal carotid artery (ICA) dissection. CASE DESCRIPTION: None of the three patients had a history of vasculopathy or trauma. All ruptured VADAs were treated with internal coil trapping in the acute stage of subarachnoid hemorrhage (SAH). Rebleeding was not observed in any patients after the treatment...

Atherosclerotic carotid artery stenosis (CS) continues to be a common cause of acute ischaemic stroke. Optimised medical therapy (OMT), the first-line treatment modality in CS, may reduce or delay - but it does not abolish - CS-related strokes. As per current AHA/ASA and ESC/ESVS/ESO guidelines, carotid artery stenting (CAS) is a less-invasive alternative to carotid endarterectomy (CEA) for CS revascularisation in primary and secondary stroke prevention. Ten-year follow-up from the CREST trial in patients with symptomatic and asymptomatic CS confirmed equipoise of CAS and CEA in the primary endpoint...

BACKGROUND: Because of the large amount of information to process and the limited time of a clinical consult, choosing between carotid endarterectomy (CEA) and carotid angioplasty with stenting (CAS) can be confusing for patients with severe symptomatic internal carotid stenosis (ICA). GOAL: We aim to develop a visual aid tool to help clinicians and patients in the decision-making process of selecting between CEA and CAS. MATERIALS AND METHODS: Based on pooled analysis from randomized controlled trials including patients with symptomatic and severe ICA (SSICA), we generated visual plots comparing CEA with CAS for 3 prespecified postprocedural time points: (1) any stroke or death at 4 months, and (2) any stroke or death in the first 30 days and ipsilateral stroke thereafter at 5 years and (3) at 10 years...

Cerebrovascular complication is the one of the most dreadful complication after open heart surgery which leads to significant decrease of quality of life even if the patients survived. To decrease these complications, carotid doppler echo as one of the non-invasive carotid screening modalities is effective. Carotid artery stenosis is common in the patients with coronary artery disease, and it is more frequent in the patients with more complexed coronary artery lesions. The more the patients indicated for coronary artery bypass grafting has complexed lesions these days, the more the patients have carotid artery lesions...

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization)...

BACKGROUND: Carotid artery stenting (CAS) is currently associated with an increased risk of 30-day stroke compared with carotid endarterectomy (CEA), whereas both interventions seem equally durable beyond the periprocedural period. Although the clinical outcomes continue to be scrutinized, there are few data summarizing the costs of both techniques. METHODS: A systematic search was conducted in MEDLINE, Embase and Cochrane databases in August 2016 identifying articles comparing the costs or cost-effectiveness of CAS and CEA in patients with carotid artery stenosis...

INTRODUCTION: Repetitive transcranial magnetic stimulation (rTMS), including theta burst stimulation (TBS), is considered helpful for functional recovery in post-stroke patients. However, the safety is a common concern forusingrTMS for neuro-rehabilitation and research in patients with stents. METHOD: Prolonged continuous theta burst stimulation (cTBS) with 1200 pulses at 50% of maximum output of Magstim Super Rapid2 was delivered in three different angles to a carotid stent placed in an isolated fresh swine carotid artery or on a table at a distance of 5cm...

BACKGROUND AND PURPOSE: Multicenter clinical trials attempt to select sites that can move rapidly to randomization and enroll sufficient numbers of patients. However, there are few assessments of the success of site selection. METHODS: In the CREST-2 (Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trials), we assess factors associated with the time between site selection and authorization to randomize, the time between authorization to randomize and the first randomization, and the average number of randomizations per site per month...

Extracranial cerebrovascular disease is one of the most important causes of death and disability worldwide and its treatment is based on clinical and surgical strategies, the latter being performed by conventional or endovascular techniques. The management of stenosis of the carotid bifurcation is mainly aimed at preventing stroke and has been the subject of extensive investigation. The role of clinical treatment has been re-emphasized, but carotid endarterectomy remains the first-line treatment for symptomatic patients with 50% to 99% stenosis and for asymptomatic patients with 60% to 99% stenosis...

Synthetic vascular smooth muscle cells (VSMCs) play important roles in atherosclerosis, in-stent restenosis, and transplant vasculopathy. We investigated the synthetic activity of VSMCs in the atherosclerotic carotid artery using (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Atherosclerosis was induced in rats by partial ligation of the right carotid artery coupled with an atherogenic diet and vitamin D injections (2 consecutive days, 600,000 IU/day). One month later, rats were imaged by F-18 FDG PET...

Iatrogenic cervical internal carotid artery pseudoaneurysm is a rare and potentially lethal complication following tonsillectomy. It can be complicated by thromboembolism, mass effect and eventually may rupture leading to death. Various endovascular treatment options are available for the management of these pseudoaneurysms, including coil embolization, detachable balloon occlusion, or stent graft placement. Parent artery occlusion using detachable balloons can be a therapeutic option in a subset of patients...
