A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
Central venous catheters (CVC) are catheters inserted into the large veins of the arm, neck, chest, or groin. CVC's are used for delivery of medications, nutrients, or blood products for a longer periods, usually weeks to months. [1] There are several reasons for the use of central venous access: [2] To get more than one drug at a time
This procedure has fallen out of favor with the development of safer techniques for central venous catheterization such as the Seldinger technique, the modified Seldinger technique, [1] [2] [3] intraosseous infusion, as well as the use of ultrasound guidance for placement of central venous catheters without using the cutdown technique.

A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
In some situations, venous access is obtained by inserting catheters into the large central veins of the trunk of the body such as the internal jugular, subclavian, or femoral veins. This type of venous access is performed with central venous catheters (CVCs) , and is required in certain situations where peripheral access is inadequate.
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
Throughout the procedure, ultrasound and X-rays may be used to confirm placement. When a central venous catheter is inserted, a chest radiologic examination is usually performed to confirm the position of the catheter and absence of pneumothorax. The chest radiologic examination is integral to the procedure.
