A Hickman line is a type of central venous catheter (CVC) that provides long-term access to a large vein near the heart. It is a thin, flexible tube inserted under the skin, usually into a vein in the chest, and tunneled to exit through the chest wall. Hickman lines are commonly used in patients who require frequent or prolonged intravenous (IV) therapy, such as chemotherapy, antibiotics, blood transfusions, or total parenteral nutrition (TPN).
By reducing the need for repeated needle punctures, the Hickman line improves patient comfort and preserves peripheral veins, which can be easily damaged during long-term treatment.
The Hickman line is placed into a large central vein, most often the internal jugular vein in the neck or sometimes the subclavian vein below the collarbone. The catheter is advanced so that its tip lies in the superior vena cava (SVC), just above the right atrium of the heart.
Unlike peripherally inserted central catheters (PICCs), the Hickman line is tunneled under the skin before it exits the chest wall. This subcutaneous tunnel acts as a barrier to infection. Many Hickman lines also have a Dacron cuff, which encourages tissue growth and helps secure the catheter in place while further lowering infection risk.
The need for a Hickman line arises from certain medical conditions and treatments where long-term, reliable venous access is essential. These include:
Cancer treatments – chemotherapy or stem cell transplants.
Hematological conditions – requiring frequent blood transfusions or plasma exchange.
Long-term IV antibiotics – for chronic infections like osteomyelitis or endocarditis.
Total parenteral nutrition (TPN) – in patients unable to eat or absorb food.
Frequent blood tests or infusions – when peripheral veins are fragile or inaccessible.
Patients with chronic illness, compromised veins, or complex treatment plans are the most likely candidates for a Hickman line.
The Hickman line itself does not cause symptoms in a healthy state, but the need for it may follow clinical signs such as:
Recurrent collapse or scarring of peripheral veins.
Discomfort or difficulty with standard IV lines.
Need for high-volume or irritant medication infusions.
After placement, patients may experience:
Temporary bruising, swelling, or tenderness at the insertion site.
A visible and palpable catheter exit site on the chest wall.
The decision to place a Hickman line is based on a clinical assessment of treatment requirements. Prior to insertion, doctors evaluate the patient’s medical history, blood clotting status, and venous anatomy.
Ultrasound is often used to guide vein selection.
Imaging (fluoroscopy or chest X-ray) confirms the correct positioning of the catheter tip in the superior vena cava after insertion.
A Hickman line itself is the chosen treatment method for central venous access. Alternatives include:
Peripheral IV lines – for short-term access.
PICC lines – inserted through the arm veins for intermediate use.
Implantable ports – devices placed under the skin, often preferred for long-term intermittent therapy.
The choice depends on treatment duration, patient preference, vein health, and risk factors.
Insertion of a Hickman line is a minor surgical procedure usually performed under local anesthesia with sedation, though sometimes under general anesthesia. The key steps include:
Preparation – The skin around the chest and neck is cleaned and draped in a sterile field.
Vein access – A large central vein (commonly the internal jugular vein) is punctured using ultrasound guidance.
Catheter tunneling – The catheter is passed under the skin from the chest wall to the vein entry site.
Positioning – The catheter is advanced so the tip rests in the superior vena cava.
Securing – The Dacron cuff is placed under the skin, and the catheter is secured with sutures or a securement device.
Confirmation – Imaging (X-ray or fluoroscopy) confirms correct placement.
The procedure typically takes 45–60 minutes.
After placement, proper care is essential to maintain the Hickman line and prevent complications:
Dressing care – The exit site is covered with a sterile dressing, changed weekly or as needed.
Flushing the line – Regular flushing with saline (and sometimes heparin) prevents blockage.
Daily activity – Patients can usually resume normal activities but should avoid heavy lifting or contact sports.
Training – Patients and caregivers are instructed on how to clean, flush, and protect the catheter.
While Hickman lines are generally safe, complications may occur, such as:
Infection at the exit site or bloodstream infection.
Thrombosis (clot formation) in the central vein.
Catheter occlusion due to blockage or kinking.
Bleeding or hematoma after insertion.
Mechanical issues such as catheter breakage or dislodgement.
Air embolism, though rare, if the line is accidentally opened to air.
With proper placement and care, a Hickman line can remain functional for months to years, depending on treatment needs. It provides reliable access and improves quality of life for patients undergoing complex therapies. Most patients adapt well to daily care routines, and with vigilance, serious complications can be minimized.
Patients with a Hickman line should seek immediate medical attention if they notice:
Fever, chills, or flu-like symptoms (possible bloodstream infection).
Redness, swelling, or pus at the catheter exit site.
Pain, swelling, or discoloration of the arm, neck, or chest.
Difficulty flushing or using the line.
Catheter damage, breakage, or accidental dislodgement.
A Hickman line is a vital tool in modern medicine, providing long-term and reliable venous access for patients with serious or chronic conditions. Understanding how it works, how it is placed, and how to care for it helps patients feel more confident and prepared during treatment. With proper maintenance and timely medical support, Hickman lines can greatly reduce the challenges of long-term intravenous therapy.
If you or a loved one requires a Hickman line, consult with a healthcare professional to discuss the benefits, risks, and care instructions tailored to your situation.
