Blood clot negligence claims

If you’ve suffered as a result of a blood clot, that wasn’t diagnosed quickly enough, or caused by the mistakes of medical practitioners, the experts at Potter Rees Dolan are here to help you claim compensation.

Blood clots are a common ailment and can vary in their severity. They can be caused by sitting in one place for too long such as during long flights (deep vein thrombosis), if your medication isn’t managed properly or by immobility after a surgical procedure.

The consequences of blood clots can be very severe, in some cases resulting in pulmonary embolism, kidney failure or even death.

The team at Potter Rees Dolan has some of the best clinical negligence solicitors in the country to help make sense of what has happened to you and to recover you the compensation you deserve. Our partners Helen Dolan, Lesley Herbertson and Gill Edwards all feature in the prestigious Legal 500 and Chambers guides, illustrating the calibre of our legal professionals.

If you think you are entitled to compensation and are ready to start your blood clot negligence claim, call us on 0800 027 2557. If you’d prefer to send us a message, please use our online enquiry form.

What are blood clots?

Blood clots are a natural part of your body’s ability to manage injuries. They are vital to encourage your body’s healing process if you have sustained a cut or similar superficial injury, but they become problematic if they form in veins or arteries and block them.

How does blood clot?

Blood clots in four stages:

  1. Platelets form a barrier - tiny parts of your blood called platelets become active when a blood vessel is damaged. They accumulate, stick to the walls of blood vessels and to each other to form a plug that fills the damaged section to stop blood from leaking out.
  2. Clot growth - specific proteins in your blood called ‘clotting factors’ trigger a rapid chain reaction. The result is a dissolved substance in your blood, turning into long strands of fibrin. These intertwine with the platelets to create a net that traps even more platelets and cells. At this point, the clot becomes tougher and more durable.
  3. Clot growth control - additional proteins in your body stop the growth of the clot to avoid it spreading further than it needs to.
  4. Breaking the clot down - once the damaged tissue has healed, your body begins to break down the clot. The fibrin strands are dissolved and your blood reclaims the platelets and cells used in the clot for future use.

What causes dangerous blood clots?

A common cause of dangerous blood clots is a lack of mobility, such as during long drives or long-haul flights. Dangerous blood clots can also form if you:

  • Have had recent surgery
  • Are aged 65 or older
  • Have previously had cancer or are receiving treatment for it
  • Have a broken bone (leg, pelvis)
  • Have sustained a bad bruise
  • Are overweight
  • Are confined to a wheelchair or bed for most of the time
  • Have a family history of blood clots

Symptoms of a blood clot

If you have a blood clot inside of your body that you cannot see, other symptoms may manifest:

  • Swelling in your arm or leg
  • Skin redness
  • Soreness or pain in your arm or leg
  • A warm spot on your leg

If you think you have a blood clot, you should seek advice from a medical professional as soon as possible. They can be dangerous, especially if they break loose and migrate into other parts of your body, including your lungs. If a blood clot has travelled to your lungs you might be suffering from something called a pulmonary embolism. The symptoms can include:

  • Difficulty breathing
  • Chest pain and tightness
  • A rapid heartbeat
  • Fainting spells
  • Fever
  • A cough that sometimes can be accompanied by blood.

If you show any of the symptoms we’ve just described, it is crucial you seek medical advice immediately.

Treating blood clots

If your blood clots are severe and need immediate treatment, most likely, you will receive blood thinners to treat the problem. In the first week, you will likely start taking a medicine called heparin. It works quickly and it is injected directly under the skin. You might also be prescribed an oral medicine called an anticoagulant.

After a week of this treatment, your medical professionals will discontinue the heparin and decide whether any anticoagulation treatment needs to continue. If this is the case, you might continue to take anticoagulants for up to six months or longer. How long the treatment needs to continue will depend on the severity of your case and what your medical professionals decide is the most appropriate treatment.

Preventing blood clots

There are actions you can take to prevent blood clots from forming in the first place. If you have reduced movement because of an injury or surgery, doctors sometimes prescribe heparin to prevent blood clots.

Medical professionals also recommend the following to help keep blood clots at bay:

  • Wear loose fitting clothes - tight fitting clothes restrict your blood flow and, as such, can encourage blood clots to form. Wearing looser fitting clothes can help with this issue.
  • Exercise frequently - exercise can help to reduce the risk of developing a blood clot. It will encourage your body to store less fat and cholesterol, reducing the risk of blood clots forming in your arteries and veins.
  • Change your diet - altering what you eat to include less saturated fats and less salt will help prevent dangerous blood clots from forming in the first place.
  • Move around frequently - it can be tempting to sit in the same position during a long car journey or flight, or even in the office for hours on end. Getting up frequently, stretching your legs and moving around in general is key to preventing blood clots from forming.


Dangerous blood clots are considered a medical emergency and as such, if you think you have one, it is imperative you seek medical assistance. Failure to identify and treat blood clots in time can have severe consequences such as:

  • Deep vein thrombosis (DVT), where the veins in your legs become obstructed by clots
  • Post-thrombotic syndrome, where your blood flows into other veins increasing blood pressure in the leg where a DVT took place
  • Pulmonary embolism, where the blood clot moves to your lungs
  • A stroke, resulting in additional complications such as paralysis
  • Loss of limbs, in some cases
  • In extreme cases, death

Medical negligence

You may have been a victim of medical negligence if any of the following points have affected you:

  • Failure to provide heparin/ prophylactic anticoagulants to prevent clots
  • Failure to diagnosis and treat a DVT
  • Failure to diagnose and treat a pulmonary embolism
  • Failure to provide clot busting drugs once a PE has occurred
  • Administering clot busting drugs unnecessarily, causing a stroke

How we can help

The clinical negligence team at Potter Rees Dolan draws upon 60 years of legal experience and has an impressive understanding of medicine to help you recover the compensation you need.

Helen Dolan is the head of the clinical negligence team. In Chambers 2018, one of the leading law publications, she has been described as “scrupulous in her preparation and organisation, highly experienced and her knowledge and insight was extremely reassuring”.

Again in Chambers 2018, a peer said of partner Lesley Herbertson: “She recently handled a delay of treatment case concerning cauda equina. She has additional capabilities in assisting with failings in district nursing and delays in diagnosis to brain injuries.”

Finally, Gill Edwards is described as “an exceptionally good solicitor” and earns praise from a client who said: “The way she helped me is amazing. She is just fantastic.”

Our clients tell us it is the empathy, passion and care our team shows that sets us apart from our competitors. We specialise in helping people with serious and catastrophic injuries, putting their needs first, and making sure they receive a comprehensive and caring service, while simultaneously making the entire claims process as stress-free as possible.


We will fund your blood clot negligence claim on a ‘no win, no fee’ basis. Our solicitors will investigate your potential claim on your behalf and you won’t need to pay anything if your case isn’t successful.

You might have an insurance policy that covers legal issues. If this is the case, we’ll identify whether you can use this policy or not at the start of your case. If it isn’t appropriate, we’ll offer you a ‘no win, no fee’ type of claim instead.

What happens next

At the very start of your case, we will discuss all the circumstances around your claim in as much detail as possible to understand whether you have a case or not. If we agree that your case should be investigated, we’ll help you obtain all of the evidence that we will need to build the best claim we can.

In this first instance, we’ll obtain evidence from your medical records. We’ll examine them in detail before sending them to independent experts to identify whether you or who you’re representing has received substandard treatment and whether this has caused the injury. When we’ve established a case for clinical negligence, we’ll follow the Pre-Action Protocol by sending a Letter of Claim and obtained a response from the Defendant.

If it is not possible to reach a settlement, it may become necessary to initiate court proceedings. We always try to progress claims as quickly as possible and explore opportunities to adequately settle your case early to obtain interim or early payments.
