Port-a-Cath (Implantable Port) Paris

What is a Port-a-Cath?

The Port-a-Cath (implantable port or PAC) is a fully subcutaneous central venous access device: a small titanium or resin port connected to a catheter whose tip sits in a large central vein, close to the heart. It is implanted under the skin of the chest wall or arm, and accessed via a simple puncture through the skin with a special needle (Huber needle). It allows repeated, long-term intravenous treatments to be given safely.

Why have a Port-a-Cath fitted? For which treatments?

Chemotherapy (the standard for long protocols), immunotherapy and targeted therapies
Repeated intravenous treatments over several months to years, and repeated transfusions or blood sampling
Avoids repeated needle punctures and preserves your veins, with better tolerance of irritant treatments
Long-term use, discreet device entirely under the skin — the standard solution for prolonged intravenous treatments

Who is this method for?

Patients needing repeated or prolonged infusions of vein-damaging products, particularly in oncology
Patients with difficult peripheral venous access

Advantages

Fully implanted: no visible catheter, showering and swimming are possible
Minimal maintenance (monthly flush if not in use)
Very long lifespan (several years)
Quality of life preserved between treatment cycles

How is it placed?

A hospital stay of a few hours, as a day case or during a hospital stay

Under local anaesthesia (± sedation)

The procedure usually takes 45 minutes to 1 hour

The catheter is inserted into a central vein (subclavian, jugular or cephalic)

The port is implanted in a small subcutaneous pocket, most often on the chest

Correct positioning is checked by imaging immediately after placement — usable from the next day

What is the recovery like?

Moderate pain at the implantation site in the first few days, with possible temporary local swelling or bruising
Rare complications during prolonged use: infection, thrombosis, device dysfunction or displacement
Specific care is required at each use (Huber needle, flushing, etc.), and monthly flushing when not in use

Removal

Removal is performed as a day case under local anaesthesia, usually at the end of treatment or in the event of a complication (infection, thrombosis).

✅ Cost: covered by French National Health Insurance. No additional fees in our centre.

Frequently asked questions

A Port-a-Cath is a small chamber implanted under the skin of the chest, connected to a central vein by a fine catheter. It provides reliable long-term venous access for chemotherapy without repeated needling of arm veins.

Under local anaesthesia with sedation, through a small incision, guided by ultrasound and X-ray, as a day case.

It can remain for months to years, and is removed once treatment is complete. It only needs periodic flushing when not in use.

Yes. Once the wound has healed, the port is entirely under the skin, so showering and swimming are possible.

Yes. At Cochin AP-HP (a French public hospital), this procedure is covered by national health insurance with no out-of-pocket fees. Please use our contact form.
