NCT ID: NCT05603221 Recruiting - Clinical trials for Renal Artery Stenosis

Renal Perfusion Assessment in the Endovascular Treatment of Renal Artery Stenosis

Start date: November 4, 2020
Phase:
Study type: Observational

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.

NCT ID: NCT03594786 Recruiting - Clinical trials for Aortic Aneurysm, Abdominal

Impact of Supra-renal Fixation of EVAR on Hemodynamics of Renal Arteries

IFIXEAR
Start date: June 1, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03530748 Recruiting - Aortic Dissection Clinical Trials

On-table Renal Perfusion Evaluation Renal Artery Stenosis or Obstruction

Start date: April 9, 2018
Phase:
Study type: Observational

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.

NCT ID: NCT03252639 Recruiting - Clinical trials for Renal Artery Stenosis

A Study of Using Parenchymal Blood Volume(PBV) for Endovascular Treatment of Renal Arterial Stenosis

Start date: November 2016
Phase: N/A
Study type: Observational

This study will use PBV technique to quantitatively assess the improvement of renal perfusion before and after endovascular treatment (EVT) of renal artery stenosis.

NCT ID: NCT02655341 Recruiting - Clinical trials for Acute Myocardial Infarction

Hydration Status Assessment Through Body Composition Monitoring in Patients With Acute Myocardial Infarction

HYD-AMI
Start date: January 2016
Phase: N/A
Study type: Observational

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.

NCT ID: NCT02388139 Recruiting - Clinical trials for Myocardial Infarction

Cardiovascular, Renal and Metabolic Profile in Patients With Acute Myocardial Infarction (REN-ACS)

REN-ACS
Start date: October 2014
Phase: N/A
Study type: Observational

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.

NCT ID: NCT01173666 Recruiting - Clinical trials for Left Ventricular Hypertrophy

Stenting of Renal Artery Stenosis in Coronary Artery Disease Study

RASCAD
Start date: April 2006
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00711984 Recruiting - Clinical trials for Renal Artery Stenosis

Comparison of Stenting Versus Best Medical Therapy for Treatment of Ostial Renal Artery Stenosis: a Trial in Patients With Advanced Atherosclerosis

Start date: February 2004
Phase: Phase 4
Study type: Interventional

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.
