Deep vein thrombosis (DVT) is a serious and potentially life-threatening condition that often develops silently, without warning. At Northern Heart Hospital, we are committed to raising awareness of DVT, providing expert diagnostic and treatment options, and empowering patients with knowledge to take charge of their vascular health. This blog explores what DVT is, why it’s crucial to recognise and treat it, the risk factors, signs, treatment options, and how Northern Heart Hospital offers comprehensive care for this condition.
What is Deep Vein Thrombosis?
Deep vein thrombosis occurs when a blood clot forms in one of the deep veins, typically in the legs, thighs, or pelvis. These clots can partially or completely block blood flow, leading to complications if not treated promptly.
While the clot itself may not always cause immediate harm, its potential to dislodge and travel to the lungs, resulting in a pulmonary embolism (PE), makes DVT a medical condition that requires urgent attention. Pulmonary embolism is a life-threatening complication that occurs when a clot blocks the blood vessels in the lungs, disrupting oxygen flow to the body.
Why is it Important to Address DVT?
Untreated deep vein thrombosis (DVT) can have serious consequences for your health, some of which may become life-threatening. One of the most severe complications is pulmonary embolism (PE). This occurs when a blood clot dislodges and travels to the lungs, blocking blood flow. PE can cause symptoms such as shortness of breath, chest pain, and, in severe cases, can be fatal.
Another potential complication is post-thrombotic syndrome (PTS), which results from long-term damage to the veins caused by the clot. This can lead to chronic pain, persistent swelling, and noticeable changes to the skin over the affected area, significantly impacting your daily comfort and mobility.
Finally, DVT can lead to reduced mobility and a diminished quality of life. The pain, swelling, and discomfort associated with the condition can make everyday tasks challenging, affecting physical activity and overall well-being.
Timely diagnosis and effective treatment of DVT are crucial not only to prevent these complications but also to safeguard your vascular health and enhance your long-term quality of life.
Understanding the Risk Factors for DVT
Certain factors can significantly raise the risk of developing deep vein thrombosis (DVT). By recognising these risks, individuals can take proactive steps to aid in early detection and prevention.
- Prolonged immobility is one of the most common risk factors. Sitting for extended periods, such as during long-haul flights, car journeys, or hospital stays, can cause blood flow to slow down, increasing the likelihood of clot formation.
- Surgery or injury, especially major procedures involving the legs or pelvis, can also elevate the risk. Tissue damage and limited mobility during recovery periods make it easier for clots to develop.
- Medical conditions, such as cancer, heart disease, or inflammatory disorders like lupus, can further increase the chance of clot formation due to their effects on the blood’s ability to clot.
- Pregnancy and hormonal factors also play a role. Hormonal changes during pregnancy can increase clotting potential, and the use of oral contraceptives or hormone replacement therapy can add to this risk.
- A family history of clotting disorders or venous disease can indicate a genetic predisposition, making it more likely that you might develop DVT.
- Finally, lifestyle factors such as smoking, obesity, and a sedentary routine significantly contribute to DVT risk. Smoking damages blood vessels, obesity puts extra pressure on veins, and lack of physical activity slows circulation, all of which make clots more likely to form.
Understanding these risk factors is the first step toward prevention, enabling individuals to make informed choices and seek medical advice when needed.
Recognising the Symptoms of DVT
The symptoms of DVT can vary from mild to severe, and in some cases, there may be no noticeable signs at all. However, common symptoms include:
- Swelling in one leg or along the vein in the affected area.
- Pain or tenderness that often starts in the calf and may feel like cramping or soreness.
- Red or discoloured skin over the affected area.
- A feeling of warmth in the affected leg.
If you experience sudden shortness of breath, chest pain, or light-headedness, these may indicate a pulmonary embolism, which requires immediate medical attention.
How is DVT Diagnosed?
At Northern Heart Hospital, we use a combination of advanced technology and clinical expertise to diagnose DVT accurately and efficiently. The diagnostic process typically includes:
- Physical Examination:
A specialist will assess your symptoms, medical history, and any visible signs of swelling, redness, or tenderness. - Ultrasound Scanning:
A Doppler ultrasound is the most commonly used test to detect blood clots. This non-invasive imaging technique visualises blood flow in the veins and identifies any blockages. - D-Dimer Blood Test:
This test measures the levels of a substance released when blood clots break down. Elevated levels may indicate the presence of a clot. - Additional Imaging Tests:
In complex cases, further imaging such as a CT or MRI venogram may be performed to obtain a clearer view of the affected veins.
Treatment Options for DVT
At Northern Heart Hospital, we offer a range of treatment options tailored to the individual needs of each patient. The primary goals are to prevent the clot from growing, reduce the risk of complications, and minimise the chances of future clot formation.
1. Anticoagulant Medications:
- Often referred to as blood thinners, these medications prevent clots from enlarging and reduce the risk of new clots forming.
- Treatment may involve oral medications, such as warfarin or newer agents like rivaroxaban, or injectable medications like heparin.
2. Thrombolytic Therapy:
- In cases where the clot is large or causing severe symptoms, thrombolytic drugs may be used to dissolve the clot. This is often administered through a catheter directly into the clot under imaging guidance.
3. Inferior Vena Cava (IVC) Filter Placement:
- For patients who cannot take anticoagulants, a filter may be inserted into the vena cava (a large vein in the abdomen) to catch clots before they reach the lungs.
5. Minimally Invasive Surgical Intervention:
- Removal of the clot (thrombectomy) may be required using keyhole techniques (minimally invasive). At Northern Heart Hospital, we have the technologies, expertise and modern facility for minimally invasive removal of the clot.

Preventing DVT: Steps You Can Take
While some risk factors for DVT are beyond control, there are proactive steps you can take to lower your chances of developing this condition:
- Stay Active:
Regular exercise improves blood circulation and reduces clotting risk. Simple activities like walking or stretching during long periods of sitting can make a significant difference. - Maintain a Healthy Weight:
Achieving and maintaining a healthy weight helps reduce pressure on your veins and improves overall cardiovascular health. - Stay Hydrated:
Proper hydration prevents blood from thickening and reduces clot formation. - Avoid Smoking:
Smoking damages blood vessels and increases clotting risk. Quitting smoking is a major step towards better vascular health. - Wear Compression Stockings During Long Travel:
These stockings improve blood flow and are particularly useful during long flights or car journeys. - Follow Medical Advice:
If you have a condition or history of DVT, follow your doctor’s recommendations regarding medication and regular check-ups.
