The ANDORRA study is a, multicenter, prospective, open, randomized, controlled blinded endpoint trial (PROBE) comparing two treatment strategies (renal artery stenting + standardized and optimized medical treatment [SOMT] versus SOMT alone) of 12 months duration in patients with confirmed resistant hypertension (RH) and angiographically proven grade III unilateral or bilateral atherosclerotic renal artery stenosis (ARAS) ≥ 60%.
Although expert consensuses recommend the use of statins in the treatment of atherosclerotic renal artery stenosis, in patients with severe atherosclerotic renal artery stenosis undergoing stent placement, the related investigation focused on renal protection by intensive lipid-lowering therapy is scant , and the optimal target level for lipid reduction remain uncertain. Therefore, we hypothesized that intensive lipid lowering could offer more benefits with respect to renal fun...
The clinical investigation is a prospective, international, multi-centre, randomized (1:1) trial with follow ups at 2, 6, 12 months and 3 years. The purpose of the study is to evaluate the clinical impact of percutaneous transluminal renal artery stenting (PTRAS) on the impaired renal function measured by the estimated Glomerular Filtration Rate (eGFR) in patients with hemodynamically significant atherosclerotic renal artery stenosis (ARAS).
This study will compare medical therapy plus stenting of hemodynamically significant renal artery stenoses versus medical therapy alone in patients with systolic hypertension and renal artery stenosis.
The interest of renal angioplasty in the nosological framework of atherosclerotic stenosis has been significantly challenged by STAR and ASTRAL clinical trials in 2009, confirmed by the CORAL study in 2014. These studies did not show any benefit of the gesture on renal function, morbidity and cardiovascular mortality or the tension control. The aim of the study is to evaluate renal angioplasty on atherosclerotic stenosis.
Background: Atherosclerotic renal artery stenosis (ARAS) is associated with progressive loss of renal function and is one of the most important causes of renal failure in the elderly. Current treatment includes restoration of the renal arterial lumen by endovascular stent placement. However, this treatment only affects damage caused by ARAS due to the stenosis and ensuing post-stenotic ischemia. ARAS patients have severe general vascular disease. Atherosclerosis and hype...
The purpose of this study is to evaluate the safety and effectiveness of the RX HERCULINK 14 Peripheral Stent System in treating atherosclerotic renal artery stenosis.
To evaluate the procedural safety and filter efficiency of the FiberNet® Embolic Protection System when used in conjunction with the Boston Scientific Express SD Stent System for primary stenting of ostial atherosclerotic renal lesions in patients with atherosclerotic renal artery stenosis.
The purpose of the study is to determine potential utility of renal fractional flow reserve in prognosis predicting after renal stent implantation.
The purpose of this trial is to test how well the iCAST™ RX Stent works in patients diagnosed with atherosclerotic renal artery stenosis and whether or not increased blood flow by the stent will help to control blood pressure.
A multicenter prospective registry planned to recruit more than 5 000 patients with renal artery stenosis was carried out in China. This primary purpose of this study was to evaluate the safety and efficacy of renal artery revascularization in the real world. The secondary purpose was to investigate the etiologic distribution of renal artery stenosis and optimize the indications for renal artery revascularization.
All patients referred for coronary angiography will simultaneously be evaluated for renal artery stenosis and then stenosis more than 50% will be analyzed according to clinical conditions, risk factors and lab data.
This study will use PBV technique to quantitatively assess the improvement of renal perfusion before and after endovascular treatment (EVT) of renal artery stenosis.
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.
The purpose of this study is to determine whether the Herculink Elite Renal Stent System is safe and effective in the treatment of renal artery stenosis in patients with less than optimal angioplasty results and uncontrolled hypertension. CAUTION: The Herculink Elite Renal Stent System Is An Investigational Device. Limited by Federal (U.S.) Law to Investigational Use Only.
The primary objective of this study is to compare the safety and performance of the Palmaz Genesis™ balloon expandable stent, with or without sirolimus coating in the treatment of renal artery stenosis, measured at 6 months follow up via angiography.
Stenosis of the renal graft arteries occurs in 1 to 26% of cases and can damage the graft. Endovascular treatment is first-line treatment. The main objective of this study is to identify the predictive factors of failure of peri-anastomotic.
CT of the abdomen is a very common examination performed for various indications.One of the common findings is vascular calcifications including calcifications of the renal arteries.Calcifications in the carotid arteries and coronary arteries are good predictor for obstructive atherosclerotic disease.Stenosis of the renal arteries can cause symptomatic or asymptomatic hypertension with subsequent clinical sequelae. Therefore early diagnosis of this condition is imperative. ...
The purpose of the study is to evaluate the safety and effectiveness of the Formula Balloon-Expandable Stent in treatment of renal artery stenosis.
The purpose of this study is to detect new ischemic lesions after carotid artery stenting (with the Cristallo Ideale stent), in patients with high grade carotid artery stenosis, by diffusion-weighted magnetic resonance imaging (DW-MRI), using the endovascular proximal flow blockage (Mo.Ma device) for cerebral protection.
1. Does primary stenting have a lower 12-month restenosis rate than PTA alone in the treatment of atherosclerotic lesions of the popliteal artery? - Alternative hypothesis: "Primary stenting with the Edwards LifeStent is associated with a lower restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery at 12 months" - Null hypothesis: "Primary stenting with the Edwards LifeStent is not associated ...
Renal artery stenosis is one the leading cause of secondary hypertension. Previous randomized controlled trials in humans have failed to demonstrate an improvement of renal function after stenosis dilation, probably because of a selection bias with more severe patients being excluded from randomization. Renal ischemia-reperfusion injuries have also not been taken into account. Indeed, reperfusion leads to a rapid renal blood flow recovery associated with renal ischemia-reperfus...
As one of the most common chronic diseases,The adult prevalence of hypertension is approximately 26.4% at present and will rise to 29.2% by 2025.Renal sympathetic denervation from the intima of renal artery has emerged as a potential treatment for resistant hypertension. However, renal sympathetic nerve are mainly located in the adventitia,and there is no report on renal sympathetic denervation from the adventitia of renal artery.This study is a multicenter,randomized,single-bl...
The purpose of the study is to evaluate the safety and effectiveness of the PTX-coating on the Formula PTX Balloon-Expandable Stent in treatment of renal artery stenosis.
Intracranial atherosclerotic disease (ICAD) is the most common cause of ischemical cerebrovascular events. The risk of stroke recurrence or death of ICAD patients remains very high. Even with aggressive medical management including dual antiplatelet therapy and strict management of risk factors, 12.2 percent of patients with 70-99 percent stenosis of intracranial artery had stroke or death during 1 year follow-up. In the real world, the 30-day risk of recurrent stroke of patien...
