Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.Similar to the Hickman line, the tip of the catheter is in the superior vena cava, and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body.
Insertion is a surgical procedure, in which the catheter is tunneled subcutaneously under the skin in the chest area before it enters the SVC. Commonly used tunneled catheters include Hickman, and Groshong, or Broviac catheters and may be referred to by these names as well. A tunneled catheter may remain inserted for months to years.
This procedure is used in certain populations such as critically ill patients or patients in hypovolemic shock or when less invasive methods such as peripheral catheters or CVCs have failed. However, in many cases the use of intraosseous access has replaced the need for venous cutdown procedures. [11] [12]
The tunnel acts as a barrier to invading microbes, and as such, tunnelled catheters are designed for short- to medium-term access (weeks to months only), because infection is still a frequent problem. Aside from infection, venous stenosis is another serious problem with catheter access. The catheter is a foreign body in the vein and often ...

Tunneled catheters have multiple channels called lumens which lay exposed on the surface of the skin. These lumens are the access points when the catheter is used. Tunneled catheters can be single, double, or triple lumened. Removal of a tunneled catheter is a simple procedure requiring only local anesthetic. A bandage is applied to the site to ...

A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein . A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.
