About Your Implanted Port

Time to Read: About 8 minutes

This information explains implanted ports, port placement, and how to care for your port. An implanted port is often called a mediport or port-a-cath. A port protects your veins during cancer treatment.

What is an implanted port?

An implanted port is a type of central venous catheter (CVC). A CVC is a flexible tube that’s put into one of your veins.

You may need to get medication in a vein larger than the ones in your arms. Your port lets the medication go into your bloodstream through your vein. It can be used to give you medication for several days in a row.

A port protects your veins from damage from repeated access. A port makes it easier for your care team to:

  • Collect blood samples.
  • Give you intravenous (IV) medication. This is medication that’s put into one of your veins. Some IV medications, such as anesthesia and some types of chemotherapy (chemo), must go through a large vein.
  • Give you IV fluids.
  • Give you IV blood products, such as platelets and plasma.
  • Give you IV contrast. This is a special dye that helps your healthcare provider see your organs better.

Your healthcare provider will tell you if getting a port is best for you and your treatment.


A surgeon or interventional radiologist (also called an IR doctor) will place your port. An IR doctor is a doctor who is a specialist in image-guided procedures. They usually will place your port in your chest. A port sometimes can go into your upper arm instead. Your healthcare provider will talk with you about where your port will be placed.

Ports placed in the chest usually are about 1 inch (2.5 centimeters) below the center of your right collarbone (see Figure 1). This allows for the most direct access to your vein. If you wear a bra, your port will be about 1 inch from where your bra strap lies.

Your port may raise your skin about ½ an inch (1.2 centimeters). You may be able to feel it through your skin. Most people will not be able to tell that you have a port.

Your port can stay in place for years. Your healthcare provider will remove your port when you don’t need it anymore. They also will remove it if it gets infected. You can have another port put in later, if you need one.

Parts of Your Implanted Port

The parts of the implanted port are the port, septum, and catheter (see Figure 2).

Port and Septum

The port is the starting point for fluids to flow through the catheter. It sits under your skin and has a raised center called a septum. This is the part of the port where needles will be placed. It’s also called the access point.

The septum is made from a self-sealing rubber material. Nothing can enter the port without a needle in it. The septum closes once the needle is removed.


The catheter is a thin, flexible plastic tube. One end is connected to your port. The other end sits in your vein.

Types of Implanted Ports

Ports can be shaped like a circle, oval, or triangle. Your port may be a Mediport®, BardPort®, PowerPort®, or Port-A-Cath®. They can be a single lumen port or a double lumen port (see figure 3). Your healthcare provider will choose the one that’s best for you and your treatments.

Single Lumen Port

A single lumen port has 1 access point. Most people get a single lumen port.

Double Lumen Port

A double lumen port has 2 access points. You can put a needle in each access point. You may get a double lumen port if you usually need more than 1 point of access for treatment.

Power-Injectable Ports

Most implanted ports are made to be used during imaging tests. These include computed tomography (CT) scans or magnetic resonance imaging (MRI). These ports let you have high speed injections (shots) of contrast. These are called power-injectable ports (see Figure 4).

Your healthcare provider will tell you if you have a power-injectable port. They will also give you a wallet card with information about your port. Carry this card with you at all times.

Getting Ready for Your Implanted Port Placement

Your port placement procedure will take place in Interventional Radiology or in the operating room. Your healthcare provider will tell you how to get ready.

Take devices off your skin

You may wear certain devices on your skin. Before your scan or procedure, device makers recommend you take off your:

  • Continuous glucose monitor (CGM)
  • Insulin pump

Talk with your healthcare provider about scheduling your appointment closer to the date you need to change your device. Make sure you have an extra device with you to put on after your scan or procedure.

You may not be sure how to manage your glucose while your device is off. If so, before your appointment, talk with the healthcare provider who manages your diabetes care.

Arrange for someone to take you home

You must have a responsible care partner take you home after your procedure. A responsible care partner is someone who can help you get home safely. They should be able to contact your care team if they have any concerns. Make sure to plan this before the day of your procedure.

If you don’t have a responsible care partner to take you home, call one of the agencies below. They’ll send someone to go home with you. There’s a charge for this service, and you’ll need to provide transportation. It’s OK to use a taxi or car service, but you still need a responsible care partner with you.

The Day Before Your Port Placement Procedure

Instructions for eating before your procedure

Do not eat anything after midnight the night before your procedure. This includes hard candy and gum.


The Day of Your Port Placement Procedure

Instructions for drinking before your procedure

‌  You can drink a total of 12 ounces of water between midnight and 2 hours before your scheduled arrival time. Do not drink anything else.

Do not drink anything starting 2 hours before your scheduled arrival time. This includes water.

What to Expect When You Arrive

Many staff members will ask you to say and spell your name and birth date. This is for your safety. People with the same or similar names may be having a procedure on the same day.

You will fill out a brief questionnaire if you have not already done so through MyMSK, the patient portal.

You will get sedation (medicine to help you feel calm) through a catheter. The catheter may be an IV in your arm or hand. It may also be a CVC, such as a peripherally inserted central catheter (PICC), if you already have one. A member of your care team will go over this with you before your procedure.

A staff member will bring you to the procedure room when it’s time to place your port.

Inside the procedure room

Once you’re in the procedure room, your healthcare provider will inject (give you a shot) of local anesthesia. Local anesthesia is medication to numb an area of your body. Your healthcare provider will inject the anesthesia into your neck and chest.

You may also need general anesthesia to have your port placed. General anesthesia is medicine to make you sleep during your procedure.

Your doctor will make a small incision (surgical cut) at the base of your neck (see Figure 5). It will be about 1 to 1.5 inches (2.5 to 4 centimeters) long. They will make a second small incision of about 0.5 inches (1 centimeter) long on your chest, under your collarbone. Then, they will make a pocket under your skin. This will hold your port in place.

Figure 5. Incision sites for port placement

Your healthcare provider will place the catheter through the second incision and connect it to your vein.

Your care team will use sutures (stitches) or surgical glue called Dermabond® to close your incisions. If you have sutures, they will be absorbed into your body. You will not need to have them removed. They may also use Steri-StripsTM. These are short, thin strips of surgical tape that are stronger than a regular bandage.

Your procedure should take about 1 hour.

After Your Port Placement Procedure

In the Post-Anesthesia Care Unit (PACU)

When you wake up after your procedure, you’ll be in the PACU. A nurse will be keeping track of your temperature, pulse, blood pressure, and oxygen levels. You may get oxygen through a tube resting below your nose or a mask covering your nose and mouth. You may also have compression boots on your lower legs. These gently inflate and deflate to help blood flow in your legs.

Tell your nurse if you’re feeling pain. They may give you medication for your pain.

Ask your nurse how long you can expect to stay in the PACU. Your care team will tell you when it’s safe to go home. You will need a responsible care partner to go with you.

Your nurse will take out your IV before you leave the hospital. They will explain how to change the dressing and care for yourself at home.

Caring for your incision site

You may feel soreness or pain at your incision sites and where the catheter was tunneled under your skin. This should get better in 1 to 2 days. You can take over-the-counter pain medication (medication you get without a prescription) if you need it. You may also notice some bruising.

Wearing a seatbelt may put pressure on your incisions. You can put a small pillow or folded towel between the strap and your body to help with this.

Incisions Closed with Sutures

If your incisions were closed with sutures:

  • You will have 2 small bandages covering your incision.
  • Leave your bandages in place for 48 hours, or as long as your healthcare provider tells you to.
  • Do not get your bandages wet. You can shower once your bandages are removed.

Incisions Closed with Dermabond

If your incisions were closed with sutures:

  • You may have small pieces of tape or bandages covering the incisions.
  • Do not apply lotion or place adhesive on top of the tape or bandage.
  • Do not pick or scratch the Dermabond. It will come off on its own after about 7 to 10 days.
  • Your care team will give you instructions for how to shower safely until your incisions heal.

The skin over your port doesn’t need any special care. You can wash it as you normally would. If your care team used Steri-Strips, these will fall off on their own in 7 to 10 days.

Your port will not set off metal detectors.

Accessing Your Implanted Port

Your healthcare provider will access your port when you need IV fluids or medication. They will do this by placing a needle through the access point (see Figure 6). The fluid or medication will move from your port through the catheter and into your bloodstream.

Only healthcare providers trained in port care should access your port.


Needle access to your port

Figure 6. Accessing your port

Your care team may need to access your port the day it’s placed. If they do, they will insert an access needle into the septum when your port is placed.

The needle and port will be covered by a special bandage (dressing) while your port is accessed (see Figure 7). The dressing will help to keep the needle in place. There also can be a small bandage over the top incision. You don’t need a bandage over your port when it’s not being used.

Figure 7. Dressing over your port

Flushing Your Implanted Port

Your port flushes on its own while it’s being used. When it’s not being used, your port will need to be flushed at least every 12 weeks. Depending on when your appointments are, a nurse may flush your port more often. To do this, they will put a needle into your port. They will inject saline (sterile salt water) into your catheter. This is done to make sure the catheter does not get blocked. Your catheter may not work if it is blocked. If this happens, you may need to have your port removed.

Removing Your Port

Your healthcare provider may remove your port when you no longer need it, or if it gets infected. Talk to your healthcare provider for more information about removing your port.

When to Call Your IR Doctor

  • If you have new or increased pain at the site of your port.
  • If you have swelling or a growing bruise at the site of your port.
