Dialysis catheter

The catheter on the left is a Vascath, and is shown in position on a CXR on the right. These are used for short term (up to 4 weeks) haemodialysis. They are typically inserted under combined ultrasound and fluoroscopy guidance into the internal jugular vein, although femoral vein insertion can also be performed. There are three lumens in the catheter – two large gauge lumens (red and blue) for inflow and outflow, and a smaller central lumen that can be used for IV therapy.
