Tunneled catheters are passed under the skin from the insertion site to a separate exit site. The catheter and its attachments emerge from underneath the skin. The exit site is typically located in the chest, making the access ports less visible than catheters that protrude directly from the neck.
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.
The most common form of venous access is a peripheral venous cannula which is generally inserted into veins of the hands, forearms, and occasionally feet. [1] Healthcare providers may use a number of different techniques in order to improve the chances of successful access.

After EVD placement, the drain is tunneled subcutaneously and secured with surgical sutures and/or surgical staples. However, it is possible for the EVD to dislodge or migrate. This will cause the tip of the drain to migrate away from its intended position and provide inaccurate ICP measurement or lead to occlusion of the drain.
