The arteriovenous fistula is the modality of choice for long-term haemodialysis access. We describe the feasibility of routinely fashioning a brachiocephalic fistula utilising a 3 mm long arteriotomy in an attempt to reduce the incidence of symptomatic steal syndrome yet while maintaining satisfactory clinical outcomes. All patients who underwent b...

Persistent left superior vena cava is an uncommon abnormality of the venous system. Most commonly, it is diagnosed incidentally during central vein catheterisation on the left side or pacemaker implantation. We present the case of a patient with persistent left superior vena cava, which was diagnosed after the attempted insertion of tunnelled haemo...

Significant venous outflow stenosis of a forearm arteriovenous fistulae caused by an extrinsic vascular compression is a very rare entity (no reported cases in the literature). We report a case of high venous pressures during dialysis, secondary to an extrinsic compression of the underlying brachial artery that was diagnosed with Doppler ultrasound...

The factors associated with the inability to start hemodialysis with an arteriovenous fistula (AVF) in chronic kidney disease patients are not fully understood. Evaluating factors associated with type of vascular access at the first chronic hemodialysis and at 1 year after it. The study cohort includes patients registered in the Regional Dialysis a...

The optimal method for teaching ultrasound guided peripheral IV (USGPIV) insertion is unknown. Poor needle tip visualization has been cited for USGPIV failure. Twinkle artifact (TA), visualized with color Doppler, is used in other clinical settings. Our objective was to investigate whether teaching students USGPIV placement utilizing TA would enhan...

Intracavitary electrocardiography is an accurate and non-invasive method for central venous access tip location. Using the catheter as a traveling intracavitary electrode, intracavitary electrocardiography is based on the increase in the detected amplitude of the P wave while approaching the cavoatrial junction. Despite having been adopted diffusel...

Timely creation and maintenance of a safe and reliable vascular access is essential for hemodialysis patients with end-stage renal disease. Hemodialysis access-induced distal ischemia (HAIDI) is a recognized complication of arteriovenous fistulas and grafts that may result in serious or even devastating consequences. Avoiding such complications is ...

Even in the best of circumstances, a significant number of patients will require adjunctive endovascular and/or surgical revision prior to achieving functional patency after endovascular or percutaneous AVF creation, at least within the United States. This rate appears to be higher after percutaneous AVF than after endovascular AVF, although becaus...

Angioplasty-related vessel rupture is a common complication of interventions. The effect of covered stents to treat venous rupture has been evaluated in smaller series, but should be further evaluated. To report the immediate outcomes and patency rates of a covered stent to rescue angioplasty-related venous rupture of hemodialysis vascular access. ...

The presence of a vascular access device (or of any intravascular foreign body) inside the bloodstream is often associated with the formation of a connective tissue sleeve around the catheter (often named-erroneously-"fibrin sleeve"). Such sleeve is usually a physiological phenomenon with little or no clinical relevance, but its pathogenesis is sti...
