Until now, no specific atherosclerosis-targeting agent labeled with positron emitter is not yet available. Investigators developed neomannosyl human serum albumin(MSA) for the terminal mannose residues of MSA binding with the mannose receptors of macrophages in atherosclerosis, and investigators investigate whether 68Ga-MSA can be a novel agent for non-invasive molecular imaging of carotid atherosclerotic lesion in PET.
The purpose of this study is to compare the safety and performance of WIRION™ EPD in patients undergoing carotid artery stenting to a performance goal based on an analysis of the results of previous US IDE carotid stenting with embolic protection studies
The aim of this prospective, randomised, controlled study is to compare the efficacy of ultrasound-guided intermediate cervical block to superficial block for carotid endarterectomy. Patients scheduled for carotide endarterectomy under regional anaesthesia (ropivacaine 4.75 mg/ml) are randomised into 2 groups according to the technique of anaesthesia performed: superficial cervical block (Control group) or, ultrasound guided intermediate cervical block (Echo group). Main outcome is cervical block success, defined by surgery performed under regional anaesthesia without supplemental topical lidocaine. Secondary outcomes are rate of conversion to general anaesthesia, total dose of supplemental topical lidocaine and block-related complications.
This study was designed to estimate the effect of two-year treatment with time-released garlic-based drug Allicor on the progression of carotid atherosclerosis in double-blinded placebo-controlled randomized clinical trial.
Major vascular surgery involves operations to repair swollen blood vessels, clear debris from blocked arteries or bypass blocked blood vessels. Patients with these problems are a high-risk surgical group as they have generalized blood vessel disease. These puts them at risk of major complications around the time of surgery such as heart attacks , strokes and death. The mortality following repair of a swollen main artery in the abdomen is about 1 in 20. This contrasts poorly with the 1 per 100 risk of death following a heart bypass. Simple and cost-effective methods are needed to reduce the risks of major vascular surgery. Remote ischaemic preconditioning (RIPC) may be such a technique. To induce RIPC, the blood supply to muscle in the patient's arm is interrupted for about 5 minutes. It is then restored for a further five minutes. This cycle is repeated three more times. The blood supply is interrupted simply by inflating a blood pressure cuff to maximum pressure. This repeated brief interruption of the muscular blood supply sends signals to critical organs such as the brain and heart, which are rendered temporarily resistant to damage from reduced blood supply. Several small randomized clinical trials in patients undergoing different types of major vascular surgery have demonstrated a potential benefit. This large, multi-centre trial aims to determine whether RIPC can reduce complications in routine practice.
The purpose of this study is to evaluate the safety and effectiveness of the MICHI™ Neuroprotection System with Filter (MICHI™ NPS+f) in providing cerebral embolic protection during carotid artery stenting. It will be used in conjunction with a FDA approved carotid artery stent for the treatment of carotid artery disease.
The aim of this study is to describe technique, efficiency, safety and satisfaction of ultrasound guided intermediate cervical plexus block for carotid endarterectomy. The investigators present a simple approach for carotid regional anaesthesia by an anterior way that has not been published yet.
This study is to investigate the possible positive effects of lutein and lycopene supplementation on early atherosclerosis in Beijing.
This is a prospective, multi-center imaging study expecting to enroll approximately 1350 patients scheduled for clinically-indicated coronary angiography. Following informed consent, patient will undergo baseline coronary intravascular ultrasound (IVUS) imaging and non-invasive ultrasound imaging of their carotid arteries. Following a 2-year follow-up period, patients will undergo repeat coronary IVUS and standard invasive coronary angiography as well as carotid ultrasound examination. Additionally, patients will be contacted by phone on an annual basis for 5 years to collect cardiovascular and cerebrovascular clinical endpoints. Evaluations of plaque burden will be made using invasive and non invasive imaging tools in order to assess correlations between vascular beds, imaging technologies and main cardiovascular events.
