What type of catheter is used for plasmapheresis?
Patients require either a double-lumen central venous catheter or two large-bore antecubital peripheral lines. Plasmapheresis can be performed using a semipermeable membrane–based device in combination with hemodialysis equipment.
How is dialysis catheter length measured?
The catheter length to be inserted in the right internal jugular vein (IJV) was calculated by adding two measurements (the shortest straight length between the insertion point of the needle and the suprasternal notch plus and half of sternal length).
What is the name of dialysis catheter?
Overview. To start hemodialysis (also called dialysis) right away, your doctor will insert a soft plastic tube into a vein. This tube will carry your blood to the dialysis machine. The tube is called a central venous catheter, or CV line.
Where is the catheter placed for plasmapheresis?
If your arm veins are unsuitable to use, interventional radiologists or surgeons will place an indwelling, double lumen catheter into a large vein in your neck or shoulder under local anesthesia.
Can a PICC line be used for plasmapheresis?
Peripherally inserted central catheters (PICC) are unsuitable and contraindicated for apheresis procedures due to the high flows and pressures which can cause rupture of the PICC.
Is a Permacath tunneled or non-tunneled?
A permcath (Also known as a permacath) is a long, flexible tube (catheter) that is inserted into a vein most commonly in the neck (internal jugular vein) and less commonly in the groin (femoral vein) but that is actually tunneled under the skin and exits usually on the leg or mid thigh.
What is a dialysis line called?
To start hemodialysis (also called dialysis) right away, your doctor will insert a soft plastic tube into a vein. This tube will carry your blood to the dialysis machine. The tube is called a central venous catheter, or CV line.
What is the maximum blood flow rate for a dialysis catheter?
Ideally, a hemodialysis catheter should be able to maintain a blood flow rate of 400 mL/min for at least 3 hours.
What is leukapheresis procedure?
Leukapheresis is a procedure used to treat chronic lymphocytic leukemia (CLL) or patients with very high white blood cell counts. During leukapheresis, your blood passes through a machine that takes out the white blood cells and returns all the other blood cells and plasma back into the bloodstream.
Can plasmapheresis be done through a port?
Tunneled central venous catheters with ports are increasingly used for therapeutic apheresis procedures. Vortex ports have been used as access for therapeutic apheresis procedures, but are not ideal for therapeutic plasma exchange (TPE) procedures due to lower flow rates.
What is an example of a non-tunneled catheter?
PICCs are non-tunneled CVCs for short-term use (i.e., weeks to months) typically inserted into the basilic vein and threaded into a larger vessel, typically the distal superior vena cava (SVC).
