What Is an Implanted Port Catheter?
An implanted port catheter is a small medical device surgically placed under the skin, consisting of a reservoir (port) connected to a thin tube (catheter) that leads to a major blood vessel. It provides reliable, long-term venous access for medications, chemotherapy, blood products, and blood sampling without repeated needle sticks.
An implanted port catheter, also known as a port-a-cath, subcutaneous venous port (SVP), or chemoport, is a specialized medical device designed to provide reliable and convenient access to the bloodstream over extended periods. The device consists of two main components: a small titanium or plastic reservoir (the port) with a self-sealing silicone membrane, and a thin, flexible catheter tube that connects the port to a large central vein.
The port is typically implanted just beneath the skin on the upper chest, below the collarbone. The attached catheter is threaded through a vein and positioned so its tip rests in a large central vein near the heart, most commonly the superior vena cava. This positioning allows medications and fluids to be rapidly diluted and distributed throughout the body, which is particularly important for chemotherapy drugs that could damage smaller veins.
When the port needs to be accessed for treatment or blood sampling, a healthcare professional inserts a special needle called a Huber needle through the skin and into the port's silicone membrane. This membrane is designed to reseal after each puncture and can withstand approximately 2,000 needle insertions, making it highly durable for long-term use. The port can remain in place for several years—typically 3 to 5 years or longer—as long as it functions properly and is needed for treatment.
Why Would I Need an Implanted Port?
Implanted ports are primarily used for patients who require frequent or long-term intravenous access. The most common indications include:
- Cancer treatment: Chemotherapy drugs are often administered through ports because they can damage smaller peripheral veins
- Long-term antibiotic therapy: Patients with chronic infections may need weeks or months of IV antibiotics
- Total parenteral nutrition (TPN): Patients who cannot eat or absorb nutrients normally may receive nutrition through a port
- Blood transfusions: Regular transfusions for conditions like thalassemia or sickle cell disease
- Frequent blood sampling: Patients requiring regular blood tests for monitoring
- Difficult venous access: Patients whose peripheral veins are difficult to access due to previous treatments or medical conditions
Implanted ports are one of several types of central venous access devices. Other options include peripherally inserted central catheters (PICC lines), tunneled catheters (like Hickman or Broviac catheters), and non-tunneled central lines. Your healthcare team will recommend the most appropriate device based on your treatment needs, expected duration of therapy, and lifestyle considerations.
How Do I Prepare for Port Implantation?
Preparation for port implantation involves showering with antiseptic soap the evening before and morning of surgery, fasting from midnight, wearing clean clothes and sleeping on clean sheets, and informing your doctor about all medications you take, especially blood thinners.
Proper preparation before port implantation surgery is essential to minimize the risk of infection and ensure a successful procedure. Your healthcare team will provide specific instructions tailored to your situation, but the following general guidelines apply to most patients.
The Evening Before Surgery
The preparation process begins the night before your scheduled procedure. These steps help reduce bacteria on your skin and lower the risk of post-operative infection:
- Shower thoroughly using the antiseptic soap or chlorhexidine solution provided by your healthcare team. You can usually purchase this at a pharmacy if not provided
- Wash your hair with the antiseptic solution as well
- Use clean towels for drying both your body and hair
- Put on freshly laundered clothes after your shower
- Sleep on clean sheets that have been recently washed
The Morning of Surgery
On the day of your procedure, you will repeat the cleansing process and follow fasting guidelines:
- Shower again with the antiseptic soap or chlorhexidine solution
- Wash your hair again with the antiseptic solution
- Use fresh, clean towels
- Wear clean clothes; hospital patients may be asked to change into hospital-provided garments
Fasting Requirements
Most patients are required to fast before port implantation surgery. This typically means:
- No eating or drinking after midnight the night before surgery
- No smoking or tobacco products
- Following specific instructions about which medications to take with small sips of water
If you take medications regularly, especially blood thinners like warfarin or aspirin, inform your doctor well in advance. You may need to adjust or temporarily stop certain medications before surgery.
You may receive pain medication before the procedure to help manage post-operative discomfort. If you feel anxious about surgery, your doctor may also prescribe a mild sedative to help you relax.
How Is the Port Implantation Procedure Performed?
Port implantation is a minor surgical procedure typically performed under local anesthesia, lasting 30-60 minutes. The surgeon makes a small incision, creates a pocket under the skin for the port, threads the catheter into a major vein, and closes the incision with stitches. Children are usually given general anesthesia.
Port implantation is considered a minor surgical procedure that is usually performed in a hospital operating room, interventional radiology suite, or specialized procedure room. The entire process typically takes 30 to 60 minutes, and most patients go home the same day.
Pre-Procedure Checks
Before the procedure begins, the healthcare team will perform several important steps to ensure your safety:
- Vital signs monitoring: Your blood pressure, heart rate, and oxygen saturation will be measured
- Oxygen saturation clip: A small clip will be placed on your finger to continuously monitor your blood oxygen levels
- Skin preparation: The surgical area on your chest will be thoroughly cleaned with antiseptic solution
- Sterile draping: Sterile cloths will be placed around the surgical site to create a clean field
Anesthesia and Sedation
For adults, port implantation is typically performed under local anesthesia, meaning you will be awake but will not feel pain in the surgical area. The process involves:
- Local anesthetic injection: The surgeon will inject numbing medication into the skin and deeper tissues. You may feel a brief burning sensation that quickly subsides
- IV placement: A temporary IV line may be placed in your arm or hand for sedatives and fluids
- Sedation (optional): Many patients receive mild sedation to help them relax during the procedure
Once the anesthesia takes effect, you will not feel pain, though you may experience some pressure or tugging sensations as the surgeon works.
The Surgical Steps
The actual port implantation involves several carefully coordinated steps:
- Incision: The surgeon makes a small incision (usually 2-3 cm) in the numbed skin of your upper chest
- Pocket creation: A small pocket is created under the skin to hold the port reservoir
- Catheter insertion: The catheter is threaded through a vein and guided into position, typically with the tip in the superior vena cava
- Port placement: The port reservoir is placed into the skin pocket and connected to the catheter
- Position verification: Imaging (such as fluoroscopy or X-ray) confirms proper catheter placement
- Wound closure: The incision is closed with sutures (stitches) that may be absorbable or require later removal
- Dressing application: A sterile bandage is applied over the incision
A nurse remains with you throughout the procedure to monitor your comfort and wellbeing.
Port Implantation in Children
Children undergoing port implantation are typically given general anesthesia, meaning they will be completely asleep during the procedure. A parent or caregiver is usually allowed to accompany the child into the operating room and stay until the anesthesia takes effect.
What Happens After Port Implantation?
After port implantation, you will spend about an hour in a recovery area while staff monitor your vital signs. Most patients go home the same day. The surgical site may be sore and swollen for a few days, manageable with over-the-counter pain medication. Stitches are typically removed after 10-14 days.
The recovery process after port implantation is generally straightforward, with most patients experiencing only mild discomfort that resolves within a few days. Understanding what to expect can help you prepare for a smooth recovery.
Immediate Post-Operative Period
Immediately after the procedure, you will be taken to a recovery area (sometimes called a post-anesthesia care unit or PACU) where:
- Your vital signs (blood pressure, heart rate, oxygen levels) will be monitored
- You will typically remain under observation for about one hour
- You can eat and drink as soon as you feel ready
- You will receive instructions for wound care and follow-up appointments
Most patients are able to go home the same day as their procedure. However, if you received sedation or general anesthesia, you will not be allowed to drive and must arrange for someone else to take you home.
The First Few Days
During the first few days after port implantation, it is normal to experience:
- Soreness and tenderness around the incision site
- Swelling and bruising in the chest area
- Mild discomfort that improves each day
These symptoms typically resolve within a few days to a week. Over-the-counter pain medications such as acetaminophen (paracetamol) or ibuprofen are usually sufficient to manage any discomfort. Your healthcare team will advise you on which medications are appropriate for you.
Wound Care Instructions
Before leaving the hospital, you will receive specific instructions about caring for your incision. General guidelines include:
- Keep the dressing clean and dry for the first 24-48 hours
- After the initial period, you may be able to shower with a waterproof dressing
- Avoid submerging the incision in water (no baths, swimming pools, or hot tubs) until fully healed
- Do not apply lotions, creams, or powders to the incision area
- Avoid heavy lifting or strenuous arm movements on the side of the port for 1-2 weeks
Stitch Removal
If your incision was closed with non-absorbable stitches, they will need to be removed approximately 10-14 days after surgery. This can usually be done at your doctor's office or the clinic where your port was placed. If absorbable stitches were used, they will dissolve on their own and do not need to be removed.
Once fully healed, a small scar will remain on your chest where the port was implanted. This scar typically fades over time and should be protected from sun exposure for the first year.
Contact your healthcare provider or seek medical attention if you experience:
- Fever or chills
- Increasing redness, swelling, or warmth at the incision site
- Drainage or pus from the wound
- Increasing pain rather than improvement
- Shortness of breath or chest pain
How Do I Live With an Implanted Port?
Living with an implanted port requires minimal lifestyle adjustments. Once healed, you can shower, bathe, swim, and exercise normally when the port is not accessed. You should protect the area from direct trauma, wear seatbelt padding if needed, and keep your port identification card with you at all times.
One of the main advantages of an implanted port over other types of central venous access devices is the minimal impact on daily life. The port sits completely beneath the skin, with no external tubes or dressings required when not in use. This allows for greater freedom and a more normal lifestyle during treatment.
Daily Activities
Once your incision has fully healed (usually within 2-3 weeks), you can resume most normal activities. When the port is not being accessed (no needle in place), you can:
- Shower and bathe normally
- Swim in pools, lakes, or the ocean
- Use saunas and hot tubs
- Exercise including most sports and fitness activities
- Travel without restrictions (the port will not trigger airport security)
However, when a needle is in place for treatment, the area must remain dry and covered. You should not shower, bathe, or swim with an accessed port.
Physical Appearance
The port creates a small, visible bump under the skin—typically about the size of a coin. Most people find this is barely noticeable under clothing. You may be able to feel the port when you touch your chest, and this is completely normal.
In the first few weeks after implantation, you may notice some discomfort when wearing certain clothing or accessories that put pressure on the port area. This typically improves as you become accustomed to the device.
Seatbelt Considerations
The position of the port may cause some discomfort when wearing a seatbelt. If this is the case, you can place a small folded towel or cushion between the seatbelt and your chest to reduce pressure on the port. Never avoid wearing a seatbelt because of your port—the safety benefits far outweigh any minor discomfort.
Activities to Avoid
While most activities are safe with an implanted port, you should avoid:
- Contact sports or activities with high risk of direct trauma to the chest
- Extreme sports that could result in significant impact to the port area
- Heavy lifting immediately after implantation (follow your doctor's guidance on when to resume)
Your Port Identification Card
When your port is implanted, you will receive an identification card with important information about your device, including the manufacturer, model, and date of insertion. You should:
- Carry this card with you at all times
- Show it to all healthcare providers when receiving medical care
- Present it before any medical imaging (some ports may affect MRI compatibility)
How Is the Port Maintained?
Port maintenance involves regular flushing every 4-8 weeks when not in active use to prevent blood clots. Flushing is performed by a healthcare professional using saline and sometimes heparin solution. During active treatment, the port is flushed after each use. The needle can remain in place for up to 7 days during treatment.
Proper maintenance is essential to keep your implanted port functioning correctly and to prevent complications such as blood clots or infections. The maintenance requirements depend on whether your port is actively being used for treatment or is in a resting period between treatments.
Regular Flushing
The most important aspect of port maintenance is regular flushing, which prevents blood from clotting inside the catheter. Flushing involves:
- Saline flush: Sterile saline solution is pushed through the port to clear the catheter
- Heparin lock (if applicable): Some ports require a small amount of heparin (blood-thinning) solution to be left in the catheter between uses. Other ports are designed to work with saline only
When your port is not being used for active treatment, it should be flushed every 4-8 weeks. Your healthcare team will advise you on the appropriate schedule based on your port type and individual circumstances.
During Active Treatment
When your port is being used for regular treatments such as chemotherapy, maintenance is incorporated into your treatment visits:
- The port is accessed at the beginning of each treatment session
- A special Huber needle is inserted through the skin into the port's membrane
- Treatment is administered through the needle
- The port is flushed with saline after each medication
- The needle is removed after treatment, or may be left in place if continuous treatment is needed
If you require treatment over multiple days, the needle can remain in the port for up to 7 days before it needs to be changed. During this time, a sterile dressing covers the needle site.
Accessing the Port for Treatment
Only trained healthcare professionals should access your port. The process involves:
- Cleaning the skin over the port with antiseptic
- Optionally applying numbing cream if desired
- Inserting a Huber needle through the skin into the port's silicone membrane
- Confirming blood return to verify proper placement
- Flushing with saline before and after treatment
- Removing the needle or securing with a sterile dressing
If you find the needle insertion uncomfortable, you can request topical anesthetic cream (such as lidocaine) to be applied to the skin over your port before access. This cream needs about 30-60 minutes to take effect, so plan accordingly for your appointments.
What Are the Possible Complications?
Complications with implanted ports are uncommon but can include infection, blood clots, catheter malfunction, and mechanical problems. Warning signs include fever, redness or swelling at the port site, difficulty flushing the port, and swelling in the neck, face, or arm. Prompt treatment of complications is essential.
While implanted ports are generally safe and reliable, like any medical device, they can occasionally cause complications. Understanding the potential problems and their warning signs allows you to seek prompt treatment when necessary.
Infection
Infection is one of the most common complications associated with implanted ports, though the risk is lower than with other types of central venous catheters. Infections can occur:
- At the skin site: The pocket where the port sits or the incision area may become infected
- In the bloodstream: Bacteria can travel along the catheter into the blood (catheter-related bloodstream infection)
- In the catheter itself: The inside of the catheter can become colonized with bacteria
Signs of infection include fever, chills, redness or warmth at the port site, swelling, pain, and drainage or pus from the incision area. Bloodstream infections may cause high fever and feeling generally unwell.
Blood Clots (Thrombosis)
Blood clots can form inside the catheter (preventing it from working) or in the veins around the catheter. Symptoms of venous thrombosis include:
- Swelling in the neck, face, or arm on the side of the port
- Pain or discomfort in these areas
- Visible enlargement of veins on the chest or arm
Clots inside the catheter may cause difficulty flushing or withdrawing blood from the port. In some cases, thrombolytic medications can dissolve the clot and restore function.
Mechanical Problems
Various mechanical issues can affect port function:
- Catheter migration: The catheter tip may move from its optimal position
- Catheter fracture: Rarely, the catheter may break, particularly if subjected to repeated pressure at certain points
- Port rotation: The port reservoir may flip or rotate under the skin, making access difficult
- Extravasation: Fluids may leak from the catheter into surrounding tissues
When to Seek Medical Care
Contact your healthcare provider or seek medical attention promptly if you experience any of the following:
- Fever (temperature above 38°C/100.4°F) or chills
- Redness, swelling, warmth, or increasing pain at the port site
- Drainage or pus from the incision or around the port
- Difficulty breathing or chest pain
- Swelling in your neck, face, or arm (especially on the port side)
- Pain when the port is being used
- Difficulty flushing the port or inability to draw blood
When and How Is the Port Removed?
The port is removed through a minor surgical procedure when treatment is complete or if complications occur that cannot be resolved. Removal is typically performed under local anesthesia and takes about 30 minutes. The surgeon makes a small incision, removes the port and catheter, and closes the wound with stitches.
An implanted port is designed to remain in place as long as it is needed for your treatment and continues to function properly. However, there are circumstances when port removal becomes necessary.
Reasons for Port Removal
Your port may need to be removed if:
- Treatment is complete: When you no longer need regular intravenous access, the port should be removed
- Persistent infection: If a port-related infection cannot be cleared with antibiotics, removal may be necessary
- Mechanical failure: If the port is damaged, displaced, or no longer functioning despite treatment
- Blood clots: Severe or recurrent clotting problems that cannot be managed otherwise
- Patient preference: Some patients prefer to have the port removed once treatment is complete
The Removal Procedure
Port removal is a relatively straightforward procedure, similar to the implantation process:
- The skin over the port is cleaned with antiseptic
- Local anesthesia is administered to numb the area
- A small incision is made over the port (often along the original scar)
- The port is freed from surrounding tissue and removed along with the catheter
- The incision is closed with stitches
- A sterile dressing is applied
The procedure typically takes about 30 minutes, and most patients go home the same day. Recovery is similar to the initial implantation, with mild discomfort and swelling that resolves within a few days.
