Port
Port (medical)
A port is a small medical appliance that is installed beneath the skin. A catheter connects the port to a vein. Under the skin, the port has a septum through which drugs can be injected and blood samples can be drawn many times, usually with less discomfort for the patient than a more typical "needle stick".
Ports are used mostly to treat hematology and oncology patients.
Types of Ports[edit | edit source]
The port is usually inserted in the upper chest (known as a chest port), just below the collar bone, leaving the patient's hands free.
Implantable Ports[edit | edit source]
Implantable ports are made of a metal body with a dense silicone rubber top. The port is inserted under the skin in the upper chest or in the arm and appears as a bump under the skin. It requires no special maintenance and is completely internal so swimming and bathing are not a problem. The patient can also travel while the port is in place.
Tunneled Ports[edit | edit source]
Tunneled ports are similar to implantable ports but have a tube exiting the body. This type of port requires some maintenance, but it can be done at home. These ports can be used for patients who need long-term therapy.
Procedure[edit | edit source]
The procedure to insert a port is done under local or general anesthesia. The port is inserted into a vein in the chest or neck. The catheter is then threaded into this vein and out through a small incision in the skin where it is attached to the port.
Risks and Complications[edit | edit source]
As with any procedure, there are risks and potential complications. These may include infection, bleeding, and blockage of the blood vessel. There is also a risk of the catheter breaking or the port becoming dislodged.
