DVT is a condition that affects both men and women and be critical if left untreated. With this in mine, it is important to understand the signs and symptoms, why it is important to understand these and learn how to prevent the condition.
What is Deep Vein Thrombosis (DVT)?
Deep Vein Thrombosis is a condition usually found in the legs as the deeper veins clot in either one or several places. The clots then tend to cause pain, swelling and if the blood clots break into the blood stream, they can then cause a pulmonary embolism. A pulmonary embolism is a life-threatening condition that occurs when a clot blocks an artery in the lungs. When experiencing a DVT and PE, this is known as a venous thromboembolism (VTE).
Statistically, DVT affects approximately 1 in 1,000 people annually.
In the UK, it is estimated that around 25,000 people die each year from venous thromboembolism (DVT and PE) highlighting the seriousness of the condition and its effects.
Approximately 10-30% of people will die within one month of diagnosis of VTE.
These statistics stress the importance of early detection, efficient and effective treatment, and preventive measures to manage DVT.
Signs and Symptoms of DVT
The importance of recognising the signs and symptoms of DVT. It is crucial for early detection and diagnosis. Signs and symptoms include:
*Swelling: Swelling in one leg or arm, alongside a feeling of warmth in the affected area.
*Pain: Pain or tenderness in the leg or arm, which might start in the calf or anywhere on the arm and feel like cramping or soreness.
*Discoloration: Redness or discoloured skin on the leg or arm.
*Warmth: A warm sensation in the affected leg or arm.
*Vein Prominence: veins will appear enlarged, and are clearly noticeable under the skin.
It’s important to note that some people with DVT may not experience any symptoms. With this in mind, it highlights the importance of being aware of the risks and preventive measures.
DVT Risks:
There are different factors that can increase the risk of developing DVT, including:
Prolonged Immobility: Long periods of sitting or lying down, such as during a long flight or car ride, can slow blood flow in the legs. It is important to stretch, rotate your feet and ankles. Try opting for a aisle seat and move as much as possible.
Surgery or Injury: Major surgery, particularly on the legs or hips, or a significant injury can increase the risk of blood clots. The use of compression socks, exercises and medication such as blood thinners may be prescribed.
Existing Medical Conditions: Certain medical conditions, like cancer, heart disease, and inflammatory bowel disease, can elevate the risk of DVT.
*Hormone Therapy: birth control pills or hormone replacement therapy (HRT) can increase clotting risk. Any concerns can be discussed with your GP.
*Pregnancy: Pregnancy increases the pressure in the veins in your pelvis and the legs. Elevating the legs frequently, stay hydrated, keep them cool and stay active will help prevent DVT.
*Obesity: Excess weight puts strain the body and increases pressure in the veins in your pelvis and legs.
*Family History: A family history of DVT or PE can also increase your risk. Genetic blood tests can be taken to highlight if you maybe at higher risk.
Diagnosing DVT
How do medical professionals diagnose this condition?
*Ultrasound: This is the most common test for diagnosing DVT. It uses sound waves to create a picture of the blood flow in the veins. The ultrasound is a safe and painless test to identify any cause for concern.
*D-dimer Test: This blood test measures a substance that is released when a blood clot breaks up. High levels of D-dimer might suggest the presence of an abnormal blood clot.
*Venography: A medical dye is injected into a large vein in your foot or ankle, and then followed by an X-ray to highlight any clots.
*MRI or CT Scans: If your ultra sound is clear but there are clear signs and symptoms of a DVT, then a MRI or CT san maybe recommended as these imaging tests can provide detailed images of the veins and help identify any clots.
*So what happens if your are diagnose with DVT? With DVT, the aim is to provide treatment prevent the clot from growing, breaking loose and travelling through the bloodstream. As well as preventing PE, the aim to is reduce the risk of recurrence. Common treatments include:
*Anticoagulants: These are known as blood thinners, which prevent new clots from forming and stop existing clots from growing. Common anticoagulants include warfarin, heparin, and newer direct oral anticoagulants (DOACs) like rivaroxaban and apixaban.
*Thrombolytics: In severe cases, the clots will need treatment to dissolve as quickly as possible. They are generally issued when there is a high risk to life.
*Compression Stockings: These can help reduce swelling and prevent post-thrombotic syndrome, a long-term complication of DVT.
Inferior Vena Cava (IVC) Filters: These filters are placed in the large vein (vena cava) in your abdomen to prevent clots from traveling to your lungs. They are usually considered when anticoagulants are not an option.
Preventing DVT
*Prevention is crucial in managing the risk of DVT. Here are some effective strategies:
*Stay Active: Regular exercise can improve circulation and reduce the risk of clot formation. Simple activities like walking and stretching can make a significant difference, especially during long periods of immobility.
*Move During Travel: If you’re travelling for long periods of time, make an effort to long periods of time by either air, rail or sea then ensure you move around every hour. Stand Stand up, walk around, stretch your legs. Rotating your ankles clockwise and anticlockwise will also help blood flow.
*Maintain a Healthy Weight: Keeping your weight in a healthy range as this helps reduce the pressure on your veins and lowers your risk of DVT.
*Stay Hydrated: Drinking plenty of fluids can help maintain healthy blood viscosity, reducing the risk of clot formation.
*Wear Compression Stockings: If you’re at high risk of DVT, your doctor might recommend wearing compression socks, especially during longer journeys which mean long periods of sitting.
*Avoid Smoking: Smoking can affect blood clotting and circulation, increasing the risk of DVT.
Deep Vein Thrombosis is a serious condition that requires awareness and proactive management. Understanding the signs and symptoms, knowing the risk factors, and adopting preventive measures can significantly reduce your risk of developing DVT. If you suspect you have DVT, seek medical advice promptly from your GP or Podiatrist to receive appropriate treatment and minimise the risk of any complications.
