A central venous catheter may be used as a vascular access when a patient has inadequate blood vessels in the limbs.

• A. False
• B. True
• C. Only for pediatric patients
• D. Never used

Answer: (B)

When the vessels in the limbs aren’t suitable for a durable fistula or graft, a central venous catheter provides a viable route for hemodialysis access. This type of catheter is placed into a central vein (often the internal jugular or subclavian, sometimes the femoral) and allows immediate, high-flow blood to be withdrawn and returned during dialysis. It is especially useful as temporary access or as a bridge while a fistula is being planned or until suitable peripheral vessels can be used. While it offers quick, reliable access, it carries higher infection and clotting risks and may have a shorter lifespan compared with mature fistulas or grafts. It’s used in both adults and pediatric patients, not just one group.
