Implanted vascular access devices

An implanted central venous access device, often referred to as an implanted port or bythe popular brand name PortACath, is a device placed under the skin without anyportion of it exiting the skin. It consists of a single or double injection port with a selfsealing silicone septum covering a metal or plastic reservoir called the body. Thecatheter connects the port and reservoir to a central vein, typically the superior venacava. An implanted port can be used to administer medication including chemotherapy,to deliver fluids, and to draw blood samples.

This type of central access device isinserted in the surgical suite or in theradiology department. The most commonsite for implanted port placement is theanterior chest, just below the clavicle.Other less common sites for implantedport placement include the upper arm,the abdomen, and the back.

Implanted Port

Implanted ports are available with singleor double lumens. A doublelumen porthas two noncommunicating reservoirs.

Advantages of implanted ports are thatthey are cosmetically appealing, theyhave the lowest risk of infection of allchestaccessed central lines, they allowpatients to carry on virtually all activitiesincluding bathing and swimming when itis not in use, and they do not requireexitsite care.

A disadvantage for the patient who has an implanted port is that accessing it can bepainful. Check for standing orders for a topical anesthetic to reduce the discomfortassociated with accessing the port.

To access the port, use a noncoring, nonbarbed (Huber) needle. Noncoring needleshave a deflected point that helps avoid septal injury by slicing through the septumwithout coring out a tiny piece of it each time the port is accessed. Most facilities’policies allow access to the implanted port with the same needle for 7 days.

Implanted ports may be openended or valved. Openended ports require heparinflushing while valved ports do not require heparin. You’ll find more details in theaccepted practice section on valve tips and openended tips. And be sure to review yourfacility’s policies addressing the frequency of flushing. When an implanted port is notaccessed, monthly flushing is usually sufficient.
