NCT ID: NCT03516929 Recruiting - Clinical trials for Assessment of Carotid Artery Stenosis and Lower Limb Peripheral Ischemia Prior to Coronary Artery Bypass Surgery

Assessment of Carotid Artery Stenosis and Lower Limb Peripheral Ischemia Prior to CABG

Start date: April 5, 2018
Phase: N/A
Study type: Interventional

From our experience among Egyptian population in our institution, there is an increased prevalence of hidden subclinical peripheral artery disease along with carotid artery affection. Thus, increasing the risk of post-operative morbid complications.We aim to evaluate routine/ non-selective carotid and peripheral arterial screening in asymptomatic patients undergoing coronary artery bypass grafting in the Egyptian populationIt is a prospective, non-randomized, comparative study including two groups of patients. The study will start from the day of approval of the ethical committee. It will include 260 patients, on basis of "all new comers". Patients will be examined and classified as "high-risk" group (ɳ = 130) or "low-risk" group (ɳ=130). All patients will have the "routine" preoperative investigations along with evaluation of extracranial carotid system by non-invasive carotid duplex and lower limb arterial system by non-invasive bilateral lower limb arterial duplex.

NCT ID: NCT03504228 Recruiting - Clinical trials for Carotid Artery Stenosis

Observational Study to Confirm Safety and Efficacy of the ROADSAVER Stent for the Treatment of Carotid Artery Stenosis

Start date: January 23, 2018
Study type: Observational

Approximately 2000 patients eligible for elective treatment with a Carotid Stent according to hospital routine practice in centers across Europe will be enrolled in the study. The maximum number of patients enrolled at each site will be not limited. Follow-ups are scheduled at discharge, 30 days, and 1 year, as per local practice. Each patient will have follow-up contacts via hospital visit and/or telephone.

NCT ID: NCT03495830 Recruiting - Clinical trials for Carotid Artery Stenosis

Stratification of Patient With Carotid Disease

Start date: March 29, 2018
Study type: Observational

Introduction: Taxinomisis trial is part of the Taxinomisis project. The concept of the Taxinomisis project is to stratify carotid artery disease relying on new modern data corresponding to contemporary patients based on information from longitudinal studies. Taxinomisis trial will validate this tool and adjust such stratification. Initial step of the project is characterization of symptomatic and asymptomatic carotid atherosclerotic plaque lesions, identification of risk and susceptibility factors through the exploitation of longitudinal cohort data and multiomics and disintegration of carotid artery disease phenotypes into endotypes through joint modeling of multipleomics data sets and systems medicine approaches. Finally such stratification model will be validated and adjusted in the Taxinomisis clinical trial.

NCT ID: NCT03488199 Recruiting - Clinical trials for Patients With Aterosclerotic Carotid Stenosis

The SIBERIA Trial (Acculink™ Versus CGuard™)

Start date: September 11, 2017
Phase: N/A
Study type: Interventional

That the study will be carried out as it has the protocol instructions, respecting the applicable regulations for clinical investigations with medical devices and following the internationally accepted ethical standards

NCT ID: NCT03464851 Recruiting - Clinical trials for Carotid Artery Stenosis

Evaluation of a Novel Technique to Diagnose Carotid Artery Stenosis

Start date: March 8, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the accuracy of a new non-invasive device, the Carotid Stenotic Scan (CSS), to check for stenosis of the internal carotid artery (ICA) as compared to a carotid ultrasound study.

NCT ID: NCT03419767 Recruiting - Carotid Stenosis Clinical Trials

Insulin Resistance in Patients After Carotid Revascularization

Start date: August 1, 2017
Phase: Phase 4
Study type: Interventional

The main purpose of this study is to study the phenomenon of insulin resistance in patients after carotid revascularization surgery through population-based, randomized, double-blind, placebo-controlled trial.

NCT ID: NCT03416257 Completed - Clinical trials for Carotid Artery Plaque

TMAO and Atherosclerosis in HIV

Start date: April 12, 2004
Phase: N/A
Study type: Observational

In the present study, the investigators sought to prospectively examine the associations of plasma levels of TMAO, choline, betaine, dimethylglycine, and sarcosine with risk of incident carotid artery plaque, assessed by repeated B-mode carotid artery ultrasound imaging over a 7-year period, in women and men with and without HIV infection from the WIHS and MACS.

NCT ID: NCT03410576 Completed - Carotid Stenosis Clinical Trials

Perioperative Time Course of MMP-9 and Its Inhibitor During Carotid Artery Stenting and Carotid Endarterectomy

Start date: October 1, 2013
Phase: N/A
Study type: Observational

The aim was the comparison of the perioperative time courses of matrix metalloproteinase-9 (MMP-9) and its inhibitor (TIMP-1) during elective carotid artery stenting (CAS). The investigators used a matched, historical carotid endarteriectomy group as controls. Blood samples at four time points: T1: preoperative; T2: 60 minutes after stent insertion; T3: first postoperative morning; and T4: third postoperative morning. Plasma was isolated from heparin anticoagulated blood samples by low speed centrifugation at 4 °C, and stored at -80 °C until analyzed in a single batch at the end of the study. Plasma concentrations of MMP-9 and TIMP-1 were expressed as ng/ml.

NCT ID: NCT03353103 Not yet recruiting - Clinical trials for Carotid Artery Stenosis

Imaging of Unstable Carotid Plaque in Patient Referred to Endarterectomy

Start date: January 2018
Phase: Phase 2
Study type: Interventional

This study will assess unstable plaque imaging features by using high resolution MR imaging and Sodium Fluoride F-18 PET. This is a comparative study between symptomatic and asymptomatic patient referred to carotid endateriectomy, with reference to pathologic analysis of plaque components

NCT ID: NCT03335033 Recruiting - Clinical trials for Carotid Artery Plaque

New Technologies to Determine Carotid Plaque Vulnerability in Patients With Significant Carotid Plaques

Start date: November 15, 2017
Phase: Phase 2
Study type: Interventional

The researchers are trying to determine if the characterization of "vulnerable" carotid artery plaques can be accomplished with ultrasound-based methods that look for vessels in the plaque and measure the plaque stiffness.
