Patients with previous surgery of the carotids or significant stenosis are not included in the study populations of baroreceptor activation therapy. In this case report about a 78-year-old woman with implantation of a baroreceptor activation therapy system two decades after bilateral thrombendarterectomy, control of hypertensive dysregulation could be observed even 20 months after implantation. Successful modulation of the baroreceptors requires intact adventitial tissue near the carotid sinus. In our case with previous longitudinal incision and patch angioplasty, the nerval innervation had been preserved...

Background: Based on the results of a recent randomized controlled trial, carotid artery stenting (CAS) was regarded as a relatively safe, less invasive treatment of internal carotid artery stenosis. However, cerebral thromboembolic events are the most common complications of CAS. Especially acute stent thrombosis following CAS will be fatal without prompt diagnosis and revascularization. Case Report: We report a case of acute stent thrombosis in whom carotid revascularization was performed successfully via arterial thrombolysis and balloon postdilation...

AIM: In-Stent Restenosis (ISR) is the major reason for recurrent ischemia and amputation after endovascular treatment of Peripheral Artery Disease (PAD). Our previous study demonstrated that miR-140-3p is significantly down-regulated in PAD arteries. However, expression and function of miR-140-3p in ISR of human PAD are currently unclear. The aim of this study is to determine the miR-140-3p expression and its regulative role in ISR of PAD. METHODS: The RNA level was determined by quantitative real-time polymerase chain Reaction (qRT-PCR) and in situ hybridization...

The short- and long-term success of intravascular stents depends on a proper re-endothelialisation after the intervention-induced endothelial denudation. The aim of this study was to evaluate the potential of in vivo molecular imaging of glutamate carboxypeptidase II (GCPII; identical with prostate-specific membrane antigen PSMA) expression as a marker of re-endothelialisation. Fifteen Sprague Dawley rats underwent unilateral balloon angioplasty of the common carotid artery (CCA). Positron emission tomography (PET) using the GCPII-targeting tracer [18 F]DCFPyL was performed after 5-21 days (scan 60-120 min post injection)...

BACKGROUND: Although earlier protease inhibitors have been associated with increased risk of cardiovascular disease, whether this increased risk also applies to more contemporary protease inhibitors is unknown. We aimed to assess whether cumulative use of ritonavir-boosted atazanavir and ritonavir-boosted darunavir were associated with increased incidence of cardiovascular disease in people living with HIV. METHODS: The prospective Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study consists of people living with HIV-1 from 11 cohorts in Australia, Europe, and the USA...

Occlusive arterial disease, including coronary heart disease (CHD) and peripheral arterial disease (PAD), is the main cause of death, with an annual mortality incidence predicted to rise to 23.3 million worldwide by 2030. Current revascularization techniques consist of angioplasty, placement of a stent, or surgical bypass grafting. Autologous vessels, such as the saphenous vein and internal thoracic artery, represent the gold standard grafts for small-diameter vessels. However, they require invasive harvesting and are often unavailable...

INTRODUCTION: The identification of carotid stenosis in patients proposed for coronary artery bypass grafting, proves that atherosclerosis is a systemic disease. In patients with carotid disease and in need of cardiac surgery, there are still questions about the best method of treatment - medical, surgical or percutaneous, the degree of stenosis considered for intervention and the best time for treatment (pre, peri or postoperative heart surgery). The surgical treatment of the carotid stenosis is currently the gold standard...

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention...

Cerebral hyperperfusion syndrome (CHS) is serious complication after carotid artery stenting (CAS) caused by decreased cerebral vasoreactivity (CVR) due to long standing hypoperfusion of the brain. We hypothesized that partial dilatation of carotid stenosis would allow the recovery of CVR, and prevent CHS when definitive angioplasty with stent is performed afterward. In this study, we aimed to evaluate the safety and efficacy of staged CAS in patients with severe carotid artery stenosis with evident hemodynamic compromise in regard to preventing hyperperfusion syndrome...

Carotid artery stenting (CAS) has been recommended as an alternative treatment to carotid endarterectomy for patients with significant carotid stenosis. Only a few studies have analyzed clinical/anatomical and technical variables that affect perioperative outcomes of CAS. Following a comprehensive Medline search, it was reported that clinical factors, including age of >80 years, chronic renal failure, diabetes mellitus, symptomatic indications, and procedures performed within 2 weeks of transient ischemic attack symptoms, are associated with high perioperative stroke and death rates...

Introduction: Despite the increasing use of carotid angioplasty and stenting (CAS), carotid endarterectomy (CEA) nonetheless remains a more medically beneficial method of treatment for carotid artery stenosis. Therefore, one possibility for progress within this procedure may be to use minimally invasive carotid surgery, especially when the scar is in plain sight: the use of the natural wrinkles (skin crease) as a camouflage of the skin incision provides significant cosmetic improvements...

Carotid endarterectomy (CEA) remains the treatment for significant carotid stenosis and stroke prevention. Approximately 100,000 CEAs are performed in the United States every year. Randomized trials have demonstrated an advantage of patch carotid angioplasty over primary closure. Complications from patches include thrombosis, transient ischemic attack, stroke, restenosis, pseudoaneurysm (PA), and infection. PA after CEA is rare, with a reported average of 0.37% of cases. We describe an unusual case of PA after polyethylene terephthalate (PTFE) patching for CEA...

Cerebral hyperperfusion syndrome (CHS) is a well-documented complication after carotid endarterectomy or stenting. In contrast, CHS following vertebral revascularization is extremely rare. Here we present a case of a 77-year-old man with high-grade vertebral stenosis who subsequently underwent balloon angioplasty, complicated by hemorrhagic CHS manifesting as cortical blindness, although strict postoperative blood pressure control was administered. To our knowledge, cortical blindness as a presentation of hemorrhagic CHS has not previously been reported...

BACKGROUND AND PURPOSE: Platelet aggregation plays a vital role in the development of in-stent restenosis (ISR) after carotid angioplasty and stenting (CAS). Mean platelet volume (MPV) has been suggested as an index of platelet reactivity. This study aimed to investigate the association between MPV and ISR in CAS patients. METHODS: A total of 261 patients with CAS were enrolled. MPV was measured before CAS procedure. Digital subtraction angiography, computed tomographic angiography, or duplex ultrasonography was performed at 6 months and annually after the procedure...

PURPOSE: Hyperglycemia is the high risk factor of vascular remodeling induced by angioplasty, and neointimal hyperplasia is strongly implicated in the pathogenesis of vascular remodeling caused by carotid artery balloon injury. Studies have shown that MicroRNA 24 (miR-24) plays an important role in angiocardiopathy, However, the role of miR-24 is far from thorough research. In this study, we investigate whether up-regulation of miR-24 by using miR-24 recombinant adenovirus (Ad-miR-24-GFP) can inhibit PDGF-BB signaling pathway and attenuate vascular remodeling in the diabetic rat model...
