A Port catheter is a type of central venous catheter used in patients requiring long-term vascular access, typically for treatments such as chemotherapy or prolonged medication administration.

The port catheter consists of a device (port) and a catheter. The port is a small device implanted under the skin, consisting of a reservoir and a connecting portion. Attached to the port is a catheter that extends into a large vein (usually the subclavian or jugular veins) and connects to the reservoir inside the port device.

Advantages of a port catheter include minimal impact on the patient’s daily life and reduced visibility. Since the port is situated under the skin, it does not interfere with activities such as bathing or exercise. Additionally, the use of a port may lower the risk of infection at the access site, as the catheter device is situated beneath the skin, reducing the likelihood of direct contact with external microbes.

Port catheters are commonly used in cancer patients requiring chemotherapy or in patients receiving frequent intravenous medication for chronic illnesses. However, they can be used in any situation requiring vascular access.

Disadvantages of a port catheter include the need for placement of a device under the skin, requiring a surgical procedure. Additionally, complications such as port occlusion, infection, or displacement can occur, albeit rarely. Nevertheless, the use of a port catheter is often preferred in patients requiring intravenous treatments for extended periods due to its practicality and comfort for long-term use.
