Ultrasound-guided angioplasty of dialysis fistula – technique description
نویسندگان
چکیده
Endovascular procedures are commonly used for treatment of vascular pathologies. These interventions are routinely performed under angiographic control. Angioplasty is increasingly more often used for correction of dialysis fistula - especially dilatation of stenosis. We describe the technique of dialysis fistula angioplasty under ultrasound control. Benefits of this procedure include lack of nephrotoxic contrast, what is especially important in chronic kidney disease patients in pre-dialysis period. Advantages of ultrasound guidance during dialysis fistula angioplasty lead to cause more and more frequent employment of this technique.

High-resolution ultrasound elasticity imaging to evaluate dialysis fistula stenosis.
Accurate, noninvasive characterization of arterial wall mechanics and detection of fibrotic vascular lesions could vastly improve the ability to predict patient response to local treatments such as angioplasty. Current imaging and other techniques for determining wall compliance rely on imprecise or indirect estimates of wall motion. This study used high-resolution ultrasound imaging with phase...
متن کاملThe use of tissue plasminogen activator as continuous infusion into an arteriovenous hemodialysis access in the hemodialysis unit: a case series
BACKGROUND Thrombolytics such as tissue plasminogen activator are often used by interventional radiologists in the radiology suite to salvage thrombosed hemodialysis arteriovenous fistulae. Thrombolytics are also commonly used in dialysis facilities as a dialysis catheter lock solution or as an infusion into a dialysis catheter when dysfunctional. However, the use of tissue plasminogen activato...
متن کاملUltrasound-guided cannulation of hemodialysis access
Because hemodialysis therapy cannot be performed without the cannulation of a vascular access, establishing a well-functioning vascular access is crucial. Recently, the number of patients with difficult arteriovenous (AV) fistula cannulation has increased due to changes in the epidemiology of the dialysis population. To address this issue, indications for real-time ultrasound-guided techniques ...
متن کاملValidation of QB stress test as a useful tool in the detection of native arteriovenous fistula stenosis: results after 22 months of follow-up.
BACKGROUND Access flow (QA) surveillance is the best method recommended for early stenosis detection, but in native arteriovenous fistula (AVF), the literature is conflicting about the real need for monthly monitoring of QA, as suggested by the K-DOQI Guidelines. METHODS From 1 January 2006 to 31 October 2007 (mean 18.0 +/- 4.9 months), we prospectively followed up 224 patients with monthly A...
متن کاملDrug-Eluting Stent for the Treatment of Early Fistula Failure
Introduction: Morbidity and mortality in chronic haemodialysis patients is related to dialysis efficiency. Several complications may occur with vascular access usually associated with a stenosis. This is known to occur frequently in the venous outflow. Stenosis of the arterial side is not as frequently discussed, but it is also likely to compromise fistula function. Traditionally, surgical and ...
