PowerPort blood clots: when a clot may be part of the port catheter lawsuits

Blood clots are one of three injury types in the federal Bard port catheter litigation, alongside catheter fracture and infection. Plaintiffs allege the catheter material can degrade and encourage clots. A clot may fit the litigation when it formed around a Bard port catheter and required treatment such as blood thinners, a procedure, or removing the port.

Maybe your arm swelled on the side of your port. Maybe a nurse could not get a blood return, and a scan found a clot around the catheter. Maybe the clot was found only after it reached your lungs.

If you had a Bard implanted port and developed a blood clot, you may have seen ads about the port catheter lawsuits and wondered whether your situation is part of them. This guide explains what the lawsuits claim about clots, how clots connected to a port are usually identified, and what a review looks at.

Why are blood clots part of the PowerPort lawsuits?

The federal PowerPort cases are consolidated in MDL 3081 in the District of Arizona. An MDL, or multidistrict litigation, gathers similar lawsuits from around the country before one judge for pretrial work, while each case remains its own lawsuit.

The lawsuits focus on the catheter, the thin tube that runs from the port into a large vein near the heart. Bard mixed barium sulfate into the catheter material so the tube shows up on imaging. Plaintiffs allege that this mixture can weaken the catheter and leave its surface rough or pitted over time. According to the lawsuits, that damaged surface can give blood a place to collect and clot, the same way it can give bacteria a place to grow or let the tube crack.

Bard denies these allegations, and no court has found the company liable for clots. The litigation groups claims into three tracks: fracture, infection, and thrombosis, the medical term for blood clots. Each track is being tested separately, because each raises different questions about what caused the injury.

The litigation is not based on a recall. A device can be the subject of product liability lawsuits without ever being recalled, and our guide on whether you need a recall to file a lawsuit explains the difference.

What does a port-related clot look like?

Clots connected to a port catheter generally show up in one of three ways.

A blocked catheter. A small clot or a sheath of clotting material can form at the catheter tip. The usual sign is that nurses can flush fluid in but cannot draw blood out, or the port stops working entirely. These blockages are often cleared with medication during a clinic visit.

A clot in the vein around the catheter. This is a deep vein thrombosis, or DVT, in the arm, neck, or chest. Common signs include swelling in the arm, hand, neck, or face on the port side, aching or heaviness in the arm, and veins that become newly visible across the chest or shoulder.

A clot that travels to the lungs. A pulmonary embolism happens when a clot breaks loose and lodges in the lungs. It can cause sudden shortness of breath, chest pain that worsens with a deep breath, a racing heartbeat, or coughing up blood.

If you have any of those pulmonary embolism symptoms right now, call 911 or go to an emergency room. A legal question can wait. That one cannot.

How are these clots usually found and treated?

Doctors typically confirm a clot in an arm or neck vein with an ultrasound. They may use a CT scan to look for a clot in the lungs, or a dye study through the port to see whether the catheter is blocked.

Treatment depends on the type of clot and your overall health. Many patients are put on blood thinners. A blocked catheter may be treated with a clot dissolving medication placed directly into the port. When a clot keeps coming back, or when the port cannot be cleared, doctors may remove the port and sometimes place a new one.

Each of these steps leaves a record, and those records are what a review relies on.

Doesn't cancer cause clots on its own?

Yes, and this is the honest complication in clot claims. Cancer raises the risk of blood clots. Many chemotherapy drugs raise it further. Any device placed inside a vein can provoke a clot, whatever it is made of. Doctors often discuss clot risk with patients before a port is placed.

That is why clot claims depend so heavily on the details. Plaintiffs argue that the problem is not that clots happen with ports, but that these catheters allegedly made clots more likely than doctors were told to expect. Bard argues that clots in cancer patients are a known and disclosed risk. Where exactly the clot formed, when it happened, what the removed catheter looked like, and what your doctors wrote down all bear on which side of that argument your records support.

None of this means you should rule yourself out. You are not expected to know whether your clot came from the catheter or from your cancer. That is a question for the records and for the attorneys who review them.

Who may qualify for a review?

A review generally looks at a few basic points:

• The device. The port was made by Bard. Ports from other manufacturers are not part of MDL 3081. If you do not know who made yours, your implant records will say.
• The connection to the catheter. The clot formed in or around the port catheter, or a clot traveled from there to your lungs.
• The treatment. The clot required care, such as blood thinners, a procedure to clear or dissolve it, hospitalization, or removing or replacing the port.
• The timing. Every state sets a deadline for filing, called a statute of limitations. In many states the clock starts when you knew, or reasonably should have known, that the device may have caused your injury. These deadlines vary, so it helps to ask early.

You may qualify even if you are unsure about some of these points. A free review confirms whether your situation fits.

What records help show the clot came from the catheter?

Clot claims turn on the paperwork more than most. The records that tend to matter most are:

• Implant records from the procedure that placed your port, which identify the manufacturer and model.
• Imaging reports that show where the clot was, especially ultrasound or CT reports that describe a clot at or along the catheter.
• Port maintenance notes, including any trouble flushing or drawing blood and any medication used to clear a blockage.
• Treatment records for blood thinners, hospital stays, and procedures.
• Removal records, including the operative report and any notes on the condition of the catheter when it came out.

Where does the litigation stand?

MDL 3081 has more than 4,000 pending cases. The court has been holding bellwether trials, which are test cases chosen to show how juries respond to the evidence. Their results do not decide anyone else's case.

Three bellwethers have been tried so far. The first, an infection case, ended in May 2026 with a jury finding for Bard on the warning claims and failing to reach a decision on the design claim. The second, a catheter fracture case, ended in September 2026 with a verdict for the plaintiff. The third, another infection case, ended in October 2026 with a verdict for Bard.

The fourth trial is the first clot case. It involves a Missouri woman who received a Bard port with a polyurethane catheter during breast cancer treatment in 2021. According to reports of her complaint, she developed an infection soon after the port was placed and later a blood clot, and the catheter was removed after two surgeries. In October 2026 the judge denied Bard's request to end the case before trial. That ruling means the judge found enough evidence for a jury to decide the design and warning claims. It is not a finding that the device was defective. The trial is scheduled to begin December 1, 2026.

There is no global settlement in the PowerPort litigation. Each case moves forward on its own facts. For a fuller picture of the litigation, see our PowerPort lawsuit explainer.

Does a review cost anything, and will you have to go to court?

The case review through Injury Advocate Group is free. If you are connected with an attorney and decide to move forward, these cases are typically handled on a contingency fee, meaning the attorney is paid a percentage of any recovery and charges nothing upfront. Fee terms are put in writing before you sign anything.

Most of the work in a case like this happens through records, phone calls, and paperwork. You do not need to travel to Arizona, and a review does not require any change to your treatment.

What should you do now?

Start with what you already know: roughly when your port was placed, when the clot was found, and how it was treated. If you have imaging reports or discharge papers at home, keep them together. A short review can tell you whether your situation fits the litigation and what a reasonable next step would be.
