Filter by:To evaluate the safety and efficacy of the Zylox Drug Coated Balloon (DCB) for treatment of subjects presenting with de novo or non-stented restenotic obstructive lesion of native arteriovenous dialysis fistulae (AVF) in the upper extremity in China.
This prospective, multicenter, randomized, controlled study is designed to evaluate the safety and effectiveness of the Tri-wire Peripheral Balloon Dilatation Catheter compared to a standard PTA Catheter in treating subjects presenting with clinical and hemodynamic abnormalities in native arteriovenous (AV) fistulae located in the upper extremity.
The absence of reliable data to establish the optimal surgical approach for creating a new Brachial Basilic Arteriovenous Fistula (BBAVF) has resulted in high degree of treatment equipoise and the decision to use one-stage or two-stage approach is largely based on surgeon's preference. The pilot trial will provide a framework for an evidence-based surgical approach to create a BBAVF for patients receiving renal replacement therapy. The pragmatic trial design will allow the inclusion of different surgical techniques currently used by the access surgeons to create a new BBAVF. Subjects in whom randomly assigned approach (one-stage or two-stage) is not completed will be considered appropriately treated as intended to account for the risk of primary fistula failure. The investigator will use the patient-centric clinical endpoints and patient reported outcomes (PROs) to incorporate the perspective of patients undergoing complex The goal is to prospectively evaluate the impact of the one-stage and two-stage BBAVF approaches on qualitative quality of life (QOL) in order to address the knowledge gap within the existing literature on complex arterovenous fistula (AVF) procedures. The investigator will use the NIH-sponsored Patient-Reported Outcome Measurement Information System (PROMIS) Computerized Adaptive Testing (CAT) tool to evaluate self-reported measures for functions, symptoms, behaviors, and feelings following the BBAVF procedure
The aim of this study is to provide an overview of the possible applications of DUS during the maturation and postoperative follow-up of vascular access, with particular emphasis to establish a relationship between doppler Ultrasound parameters including: 1. Flow volume. 2. Outflow vein diameter. 3. Outflow vein depth. 4. Resistive index.
The transplant is the definitive treatment of renal insufficiency, in our days. While waiting for it, the arteriovenous fistula surgery is standard procedure.
To investigate the effect of pre-operative exercise on 1. Hemodynamics in the fistula artery and vein, pre and post AV fistula formation 2. Suitability of cannulation of AV fistula at 8weeks
The purpose of this randomised clinical trial is to evaluate the efficacy of drug-eluting balloon compared to conventional balloon in balloon-assisted maturation of non-maturing arteriovenous fistula in adult renal failure patients.
Pulmonary arteriovenous malformations (PAVMs) are a rare vascular condition affecting the lungs. PAVMs lead to low blood oxygen levels, yet are very well tolerated by patients. This study will examine the exercise capacity of PAVM patients using formal cardiopulmonary exercise tests performed on a stationary bicycle, and whether this is affected by the presence of concurrent airflow obstruction, such as due to asthma.
The purpose of the study is to investigate the efficacy of the ROX coupler in treating patients with tilt test proven Neurally mediated syncope.
The purpose of this study is to compare the effect of DSA guided percutaneous balloon dilatation, ultrasound guided percutaneous balloon dilatation and surgical repair in the treatment of Stenosis of Arteria-Venous Fistula in Maintenance Hemodialysis Patients.
