Filter by:This is a prospective, randomized, multi-center clinical trial for chronic kidney disease (CKD) patients referred for creation of a new arteriovenous fistula (AVF) in order to assess the safety and effectiveness of SelfWrap, a bioabsorbable perivascular wrap.
To evaluate the preliminary efficacy of combination of cutting and drug-coated balloon for the treatment of resistant AVF stenosis.
study the risk factors of thrombosis in thrombosed arteriovenous fistula in patients on regular hemodialysis
A functioning dialysis vascular access is critical to the delivery of lifesaving hemodialysis. Arteriovenous graft (AVG) is a surgically created vascular access used for hemodialysis in patients with end-stage renal disease. AVG thrombosis due to underlying flow-limiting stenosis of the graft vein junction and outflow veins is a common complication. Thrombosed AVG can be treated with thrombolysis combined with percutaneous transluminal angioplasty with good immediate success rates. However, the mid-to-long term patency rates following angioplasty have been suboptimal. Sirolimus drug-coated balloon has been shown to be safe and effective in the salvage of thrombosed arteriovenous graft. The investigators hypothesize that sirolimus drug-coated balloon is non-inferior to stent graft in maintaining the patency of thrombosed AVG that is successfully salvaged. This study is conducted to compare the 6-month access circuit primary patency of thrombosed AVG treated with sirolimus drug-coated balloon versus stent graft.
The number of elderly hemodialysis patients is growing. Vascular access complications are a major determinant of the quality of life and health care costs for these vulnerable patients. The three different types of vascular access, i.e. autologous arteriovenous fistulas, arteriovenous grafts, and central venous catheters, have never been compared in randomized controlled trials. This project will deliver the much-needed evidence to determine the optimal strategy for vascular access creation in elderly hemodialysis patients in order to deliver better health care at lower costs.
We divided into three parts to carry out. Firstly, evidence the pre-existing fibrosis in vein of AVF failure patients. investigation of expression, the role, and the mechanism by which the identified O-GlcNAac proteins promote, maturation of AV fistula. Finally, ddress and compare the proteomics differentiation between failure and maturation of AVF patients.
This study compares the analgesic efficacy of supraclavicular brachial plexus nerve block to axillary nerve block techniques in adults undergoing AV fistula creation. Both these techniques will be done under ultrasound guidance, using the same local anesthetic drug. 120 patients will be included in this study, 60 patients for each technique. This study will help us know better regional anesthesia techniques, the additional need for analgesia/anesthesia, and the recovery rate following either of the blocks for AV fistula surgery. An interim analysis will be done after recruiting 50% of cases (30 cases) in both arms.
We wish to examine Arterio-Venous Fistula (AVF) and Arterio-Venous Graft (AVG) utilisation rates for Haemodialysis at University Hospital Limerick. We want to determine out of the AVF's that are surgically created, how many go on to be used as anticipated for haemodialysis treatments successfully.
An early feasibility study of the the initial safety and efficacy of the Velocity Percutaneous Arterio-Venous Fistula (pAVF) System when used to percutaneously create an arteriovenous fistula in patients with ESRD requiring hemodialysis vascular access.
Isometric exercise can effectively promote the vascular function of arteriovenous fistula and increase hand grip strength, but patients needs to perform isometric exercises patiently. The purpose of this study want investigate the effect of using individual intelligent devices for forearm isometric exercise training on the increase of arteriovenous fistula vascular function and hand grip strength, and the improvement of patients' adherence with forearm isometric exercise.
