Port-A Catheter: Key Facts
- Chemotherapy drugs can damage veins, making peripheral veins unsafe.
- A Port-A catheter provides a reliable access point for repeated injections.
- Removal is considered 1-2 years after chemo if no recurrence occurs.
- Ports can be used for blood tests but require special needles and flushing.
- High-pressure ports allow contrast injections for better imaging.
What Is a Port-A?
A Port-A catheter, also called an artificial blood vessel, replaces veins for repeated treatment access.
Indications for Port-A Catheter
1. Cancer patients on chemo or immunotherapy
2. Patients requiring long-term IV nutrition
3. Blood disorder patients needing transfusions
4. Long-term use of strong medications
Port-A Surgery: Pre-Op Notes
1. 30-minute outpatient procedure, no hospitalization.
2. Inform the doctor if on blood thinners, have clotting issues, arrhythmia, or a pacemaker.
3. No fasting needed; take regular meds except blood thinners.
Local vs. General Anesthesia
Most patients need only local anesthesia for pain control. General anesthesia is required for those with neurological surgery history, epilepsy, or permanent tracheostomy with excessive secretions.
Postoperative Care
The port can be used immediately if needed, as the injection site is covered by normal skin.
No special wound care is required, but keep the area dry for a week. Avoid shoulder rotation and stretching movements, such as yoga.
Contraindications
Port-A implantation has no absolute contraindications but requires adjustments in certain conditions:
1. Bleeding disorders
2. Regular use of blood thinners (may require temporary discontinuation)
3. Implanted pacemaker (needs mode adjustment by the manufacturer)
Potential Complications
Reoperation is needed if the following occur, though the risk is only 1-2% with standard implantation:
1. Catheter or skin flap infection
2. Catheter displacement
3. Deep vein thrombosis
4. Catheter fracture

Specialized Excellence
Prevent Pneumo/Hemothorax
Use native veins first, ultrasound if needed.
Preserve Native Veins
Avoid internal jugular puncture with venography.
Vascular Assessment
Determine optimal access route.
Shorter Surgery
Use CT/ultrasound to check veins.
Quality Monitoring
X-ray confirms catheter position and connection integrity.

Port-A FAQ
How Long Does a Port-A Last?
A Port-A catheter is typically kept for 2-3 years, until treatment is complete and follow-up confirms no recurrence.
Made from biocompatible materials (polyurethane, silicone, titanium), it generally does not trigger immune reactions but may degrade over time due to material fatigue.
When Should a Port-A Be Removed?
1. Complications: Immediate removal if infection, displacement, thrombosis, or catheter fracture occurs.
2. After Treatment:
‧For post-surgery cancer patients, removal is considered after 1-2 years of stable follow-up (total placement ~2-3 years).
‧For those on long-term systemic therapy (chemo, immunotherapy, targeted therapy), removal depends on tumor control and oncologist evaluation.
How Often Should a Port-A Be Flushed?
A Port-A is a closed system that must be flushed after each use to prevent residue buildup.
During treatment breaks, it is typically flushed every 3 months during oncology follow-ups.
Does a Port-A Contain Metal?
Yes, the injection port may have a titanium base, but all materials are highly biocompatible and do not cause adverse reactions.
How Much Does a Port-A Cost?
Some models are covered by National Health Insurance (NHI), making the cost fully reimbursed for eligible patients.
Does Getting a Port-A Hurt?
Local anesthesia is used during the procedure, causing brief discomfort when injected.
Once numb, there is no pain, but sensations of pressure remain.
After anesthesia wears off (1-2 hours), patients may feel tightness or a foreign body sensation, which typically fades within 2-3 days.
What If a Port-A Gets Infected?
If infection occurs, the port may need to be removed.
After 7-10 days of antibiotic treatment, a new port can be placed once the infection is under control.
