Filter by:The clinical benefits of endovascular treatment in renal artery stenosis remain controversial. This study uses arterial spin labelling MRI and flat-panel detector parenchymal blood volume imaging to observe the change in renal perfusion after endovascular treatment in renal artery stenosis.
The investigators conducted a bicentric prospective study to quantify the hemodynamic disturbances to the ostia of the renal arteries generated by the implantation EVAR with suprarenal fixation immediately postoperatively.
1. Evaluate the feasibility for the on-table evaluation of the renal perfusion by using Syngo Dyna Parenchymal Blood Volume(PBV) Body; 2. Explore the clinical benefits of this application during procedure to help the physician to determine the procedure endpoint.
This study will use PBV technique to quantitatively assess the improvement of renal perfusion before and after endovascular treatment (EVT) of renal artery stenosis.
Aims: - evaluate the hydric status through bioimpedance spectroscopy in consecutive acute myocardial infarction patients referred for primary PCI; - assessment of renal artery stenosis incidence through renal angiography in consecutive STEMI patients; - fully characterize the complex hydration, metabolic and endothelial profile of these patients in the attempt to define the role played by dehydration in the complex dynamics of acute myocardial infarction.
Aims - assessment of renal artery stenosis incidence in consecutive AMI patients included in the Romanian National Programme of Primary Percutaneous Revascularisation; - generating a cardio-renal-metabolic profile in patients with renal atherosclerotic disease; - creating a local registry (based on European CARDS percutaneous interventional registries) which also includes renal, metabolic and vascular data; - reporting long-term follow-up data on major cardiac adverse events (MACE) in the study group.
The Stenting of Renal Artery Stenosis in Coronary Artery Disease (RASCAD) study is a randomized controlled trial designed to evaluate the effect of renal artery stenting+medical therapy versus medical therapy alone on left ventricular mass progression and cardiovascular morbidity and mortality in patients affected by coronary artery disease and renal artery stenosis.
Renal artery stenosis (RAS) usually refers to a disease of the large extra-renal arterial vessels and most frequently is caused by atherosclerotic obstructions. The prevalence of atherosclerotic RAS increases with age, male gender, traditional cardiovascular risk factors (hypertension, diabetes, smoking, hyperlipidemia) and atherosclerotic comorbidities like coronary artery or peripheral artery disease (PAD). A prevalence up to 40% has been reported in patients with PAD. Undoubtedly, atherosclerotic RAS is a progressive disease, as more than half of the patients exhibit an increasing degree of stenosis within five years after diagnosis, and one out of five patients with a critical stenosis (>60%) suffers renal atrophy and renal failure during this period. RAS may be treated conservatively by so called best medical treatment, surgically, or by endovascular interventions using balloon angioplasty and stenting. The purpose of the investigators study is to determine the incidence and the predictors of RAS in patients with PAD, and to compare the effect of renal artery stenting versus best medical treatment in patients with hypertension and ostial renal artery stenosis in a randomized controlled trial.
