Venous valve–related occlusion in thrombosed arteriovenous fistulas: outcomes of ultrasound-guided percutaneous transluminal angioplasty

Paper C Peer reviewed Observational

Key takeaways

People on dialysis often have a surgical link between an artery and a vein in the arm, called a fistula, used to connect to the machine. This study looked at fistulas that clotted shut because of a valve inside the vein, then reopened them with a balloon threaded through the skin, guided by ultrasound. It reports how those repairs turned out. Patients were followed rather than randomly assigned, so it shows a link, not proof of cause.
