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 tunneled vs non-tunneled portion was well defined with links to the different catheters if further reading were desired. The implanted ports section was also well written with an appropriate picture accompanying the section.
