A port placement is a minor surgery to implant a small, round device just under your skin that gives medical teams direct access to a large vein. The port connects to a thin, flexible tube (catheter) that threads into a vein near your heart, creating a reliable entry point for chemotherapy, IV medications, blood draws, and other treatments that would be difficult or painful through a standard IV. The entire device sits beneath the skin, so nothing is visible or hanging outside your body between treatments.
What a Port Actually Looks Like
A port is roughly the size of a quarter or a nickel, depending on the model. It has three main parts: a small chamber (the reservoir), a self-sealing rubber top called a septum, and the catheter that runs from the chamber into your vein. The housing is typically made from titanium or a medical-grade plastic called polysulfone. The septum is silicone, designed to reseal itself after being punctured hundreds of times by a special needle. The catheter itself is soft polyurethane tubing.
When you need treatment, a nurse inserts a special angled needle called a Huber needle through your skin and into the septum. Medication flows through the needle, into the port chamber, through the catheter, and directly into your bloodstream. When treatment is done, the needle comes out and the port sits quietly under your skin until next time.
Why You Might Need One
Ports are most commonly placed for people receiving chemotherapy, but they’re used any time someone needs frequent or long-term IV access. Chemotherapy drugs can damage smaller veins in your hands and arms, causing pain, scarring, and eventually making it harder to find a usable vein. A port bypasses that problem entirely by delivering medication into a large central vein that can handle stronger drugs.
Beyond chemotherapy, ports are used for long-term antibiotic therapy, repeated blood transfusions, IV nutrition (for people who can’t eat normally for extended periods), and frequent blood draws. If your treatment plan involves IV access more than a handful of times, a port is often a better option than getting stuck with a new IV each visit.
Where the Port Goes
Most ports are placed under the skin on the right side of the chest, typically about an inch below the center of your collarbone. This spot provides the most direct path to a large vein. In some cases, a port can be placed on the inner side of the upper arm or in the abdomen below the ribcage, though chest placement is by far the most common.
Once healed, the port looks like a small bump under your skin. Most people can feel it if they press on the area, and it may be faintly visible in thinner individuals, but it’s not obvious under clothing.
What Happens During the Procedure
Port placement is a minor outpatient surgery, usually taking 30 to 60 minutes. You won’t need to stay overnight. For adults, the typical approach involves sedation (a light sleep where you’re technically conscious but won’t remember the procedure) combined with local anesthesia to numb the surgical area. Children generally receive general anesthesia so they sleep more deeply.
The surgeon makes a small incision at the base of your neck, roughly 1 to 1.5 inches long, and a second smaller incision on your chest below the collarbone. They create a small pocket under the skin to hold the port in place, then thread the catheter through the second incision and connect it to the vein. The incisions are closed with stitches or surgical glue. Imaging guidance (usually fluoroscopy or ultrasound) helps the surgeon confirm the catheter is positioned correctly.
Recovery After Placement
Most people go home the same day. You can expect soreness, swelling, and bruising around the incision sites for the first several days. Over-the-counter pain relievers are typically enough to manage discomfort. The area will feel tender, and you may notice a pulling sensation in your chest or neck when you move your arm on that side.
Your incisions need to stay clean and dry while they heal. Most care teams will give you specific guidance on when you can shower, usually once the incisions have had a couple of days to begin closing or once any dressings are removed. Swimming and submerging the area in water takes longer and should wait until the sites are fully healed. Heavy lifting and vigorous arm movements on the port side are typically restricted for a short period after placement to let the pocket and catheter settle into position.
The port can often be used for treatment within a day or two of placement, though some providers prefer to wait until swelling subsides. One study from the Mayo Clinic found no significant increase in infection or complication rates when ports were accessed immediately after placement compared to waiting.
Keeping Your Port Working
Even when your port isn’t being used for treatment, it needs periodic flushing to prevent blood clots from forming inside the catheter. The standard schedule is a flush with saline (and sometimes a small amount of a blood-thinning solution) every four weeks. If your port is being used regularly for treatment, it gets flushed before and after each use, which keeps it clear on its own.
Between treatments, when no needle is in place, the port requires essentially no daily maintenance. There’s no dressing to change, no tube to clean, and no restrictions on bathing or most physical activities once you’re fully healed. This is one of the biggest advantages over other types of central lines, which have external components that need constant care.
Risks and Complications
Port placement is considered low-risk. The overall complication rate in one Mayo Clinic study was 0.6%, with complications including a blood clot within the port, a blood collection causing skin damage, and one infection. Infection is the most commonly discussed risk, but rates are low, particularly when the port site is properly cared for during the healing period.
Other potential but uncommon complications include the catheter shifting out of position, a collapsed lung during placement (since the surgeon is working near the top of the chest), and, over very long periods, the catheter becoming blocked by a clot. Signs that something may be wrong include redness, warmth, or swelling at the port site, fever, pain during infusions, or fluid leaking around the needle during treatment.
How Long a Port Lasts
Ports are built for long-term use. The silicone septum is rated to withstand hundreds to over a thousand needle punctures, depending on the model and needle size used. In practice, many patients keep their ports for years, sometimes the entire duration of a multi-year treatment plan. As long as the port flushes easily and shows no signs of infection or malfunction, it can stay in place.
Getting the Port Removed
When you no longer need your port, removal is another minor procedure. A surgeon makes a small incision over the port site, disconnects the catheter from the vein, and lifts the port out of its pocket. Like placement, this is typically done under local anesthesia with sedation, and you go home the same day. Recovery mirrors placement: some soreness and bruising for a few days, with a small scar left behind.
The timing of removal depends entirely on your treatment plan. Some people have their port removed shortly after finishing chemotherapy, while others keep it in place for months afterward in case additional treatment is needed. There’s no medical urgency to remove a functioning port, so the decision is usually a conversation between you and your care team about whether you’re likely to need it again.
