Are there any contraindications for using a DVT Prevention Unit?

Jun 25, 2025|

Hey there! As a supplier of DVT Prevention Units, I often get asked about the contraindications of using these devices. It's an important topic, as understanding the limitations can help ensure the safe and effective use of our products. So, let's dive right in and explore if there are any contraindications for using a DVT Prevention Unit.

First off, let's quickly explain what a DVT Prevention Unit is. A DVT Prevention Unit, also known as a DVT Compression Unit, is a medical device designed to prevent deep vein thrombosis (DVT). DVT is a condition where blood clots form in the deep veins, usually in the legs. These clots can be dangerous because they can break loose and travel to the lungs, causing a pulmonary embolism, which can be life - threatening.

The DVT Prevention Unit works by applying intermittent compression to the legs, which helps to improve blood circulation and prevent blood from pooling and clotting. It's a non - invasive and relatively easy way to reduce the risk of DVT, especially for people who are at high risk, such as those who have had surgery, are immobile for long periods, or have certain medical conditions.

Now, onto the contraindications. There are indeed some situations where using a DVT Prevention Unit might not be a good idea.

1. Open Wounds or Skin Infections

If a person has open wounds or active skin infections on the legs, using a DVT Prevention Unit can be problematic. The compression applied by the device can cause pain and may even spread the infection. The pressure can also disrupt the healing process of the open wounds. For example, if someone has a fresh surgical incision on their leg or a severe case of cellulitis (a common skin infection), it's best to avoid using the unit until the wound has healed and the infection has cleared up.

2. Peripheral Vascular Disease

People with peripheral vascular disease (PVD) have problems with the blood vessels in their extremities, usually the legs. These problems can include narrowed or blocked arteries, which reduces blood flow. In such cases, the compression from a DVT Prevention Unit can further restrict blood flow. The device is designed to increase blood circulation, but in patients with PVD, it may actually cause more harm by putting additional pressure on the already compromised blood vessels. This can lead to increased pain and even tissue damage in severe cases.

3. Edema Due to Heart or Kidney Failure

Edema is the swelling caused by an accumulation of fluid in the tissues. In the case of heart or kidney failure, the edema is a result of the body's inability to properly regulate fluid balance. Using a DVT Prevention Unit on a person with this type of edema can be counterproductive. The compression may not effectively reduce the swelling and can actually cause discomfort. Moreover, the underlying heart or kidney problems need to be addressed first, and the use of the unit may interfere with the overall treatment plan.

4. Recent Fractures

If a person has recently suffered a fracture in the leg, using a DVT Prevention Unit can be dangerous. The compression can cause pain at the fracture site and may even disrupt the healing process. The movement and pressure from the device can potentially shift the broken bones, which can lead to improper healing or other complications. It's usually recommended to wait until the fracture has healed sufficiently before considering using the DVT Prevention Unit.

5. Severe Arterial Insufficiency

Severe arterial insufficiency means that there is a significant reduction in blood flow through the arteries. This can be due to various reasons, such as atherosclerosis (hardening of the arteries). When using a DVT Prevention Unit on someone with severe arterial insufficiency, the compression can further reduce the already limited blood supply to the tissues. This can lead to tissue ischemia (lack of oxygen) and potentially gangrene in extreme cases.

6. Sensory Impairment

People with sensory impairment, such as those with diabetic neuropathy, may not be able to feel pain or discomfort properly. This can be a problem when using a DVT Prevention Unit because if the compression is too tight or causing damage, they may not be aware of it. As a result, there is a risk of tissue damage going unnoticed, which can lead to serious complications.

7. Deep Vein Thrombosis Already Present

If a person already has a diagnosed deep vein thrombosis, using a DVT Prevention Unit is generally not recommended. The compression can potentially dislodge the clot, which can then travel to the lungs and cause a pulmonary embolism. In this case, medical treatment, such as anticoagulant medications, is usually the first step, and the use of a DVT Prevention Unit may need to be carefully evaluated by a healthcare professional.

It's important to note that these are general contraindications, and each case should be evaluated on an individual basis. A healthcare provider should always be consulted before starting to use a DVT Prevention Unit, especially if a person has any pre - existing medical conditions.

Contraindications for Cold Therapy in DVT Prevention Units

If a person has poor circulation, cold therapy can further reduce blood flow. Just like with PVD, the cold can cause the blood vessels to constrict, which is not ideal for someone who already has problems with blood circulation. Also, people with Raynaud's disease, a condition where the blood vessels in the fingers and toes overreact to cold temperatures, should avoid cold therapy in DVT Prevention Units. The cold can trigger severe episodes of vasospasm, leading to pain and discoloration of the skin.

In conclusion, while DVT Prevention Units are a great tool for reducing the risk of deep vein thrombosis, they are not suitable for everyone. It's crucial to be aware of the contraindications and to consult a healthcare professional before using the device.
