Central venous catheters (CVC), also known as central venous lines (CVL), refer to a wide range of catheters that are inserted so that their distal tips lie in a central vein[1]. Central venous access devices can broadly be divided into four categories. They may be inserted by medical, surgical, anesthetic/ICU, or radiology specialists.

Central venous catheters can be inserted into a variety of veins, most commonly including:

Policy varies by institution but tip placement for neck/thoracic/upper limb CVCs in the superior vena cava[2] or at the cavoatrial junction[3] is generally acceptable. There is a limited differential of left paramediastinal catheter positions[4].

Ultrasound-guided CVL insertion is proposed to reduce the number of complications and to increase the safety and quality of central venous catheter (CVC)[5] placement.
