Hemodylesis Catheter

A hemodialysis catheter is a large-bore, dual-lumen catheter inserted into a central vein to provide temporary or semi-permanent vascular access for hemodialysis. It is used when a patient’s kidneys have failed (Stage 5 Kidney Disease) and a permanent access option like an arteriovenous (AV) fistula or graft is not yet functional.

Key components and features

• Material: Made from biocompatible, flexible materials like polyurethane or silicone to reduce trauma to the blood vessel wall.
• Extensions: Features external extension legs, or “pigtails,” that connect to the dialysis machine. Curved extensions are often used for neck placement to improve patient comfort.
• Securement: Includes a securement device or a cuff to fix the catheter in place and prevent displacement.
• Radiopaque: The catheter and/or a radiopaque line are visible on X-ray, allowing clinicians to confirm correct placement.
