How To Recognize A Deep Vein Thrombosis
With a deep vein thrombosis, a blood clot forms in a large vein located deep in the muscle layers, usually in the lower leg. Find out more about this topic today.
Detecting deep vein thrombosis (DVT) is especially important for people with circulatory problems. Before we get into this problem, let’s briefly define what it is about.
A thrombosis is when a blood vessel becomes blocked by a blood clot. In deep vein thrombosis, the blood clot forms in a large vein located deep in the muscle layers, usually in the lower leg.
Certain diseases can cause this type of thrombosis. The risk of this is also greater after an operation or after an accident. A lack of exercise is also a possible trigger.
In many cases, the deep vein thrombosis goes unnoticed and resolves on its own. But it can also be a very serious situation if the blood clot is washed into the lungs through the bloodstream. This could lead to a pulmonary embolism. The blood clot could also reach the heart and cause myocardial infarction.
Causes of deep vein thrombosis
DVT often has a disruption in the return of blood from the veins further away (often in the legs) to the heart. The result is edema and swelling.
For example, a blood clot can cause the blood in a vein to work too slowly. Furthermore, blood clotting could be disturbed or a vessel wall injured. These complaints impede proper blood circulation.
As mentioned earlier, the risk is increased after surgery. However, certain medications or a lack of exercise (for example, due to longer bed rest) can promote deep vein thrombosis.
In a nutshell, the following factors can lead to deep vein thrombosis:
- Genetics: Circulatory problems can arise from genetic diseases.
- Longer rest periods, for example through hospital stays
- Injuries or operations
- pregnancy
- Smoke
- Overweight or obesity among others
How can deep vein thrombosis be diagnosed?
A doctor can use various tests to determine whether a deep vein thrombosis is present. Imaging techniques and blood tests are also important tools.
It should not be forgotten that other diseases can have similar signs and symptoms; for example pulmonary embolism, muscle injuries, cellulite or phlebitis.
The following tests are very helpful in differential diagnosis:
Duplex ultrasound (“Doppler”)
An ultrasound scan can be used by the doctor to monitor the blood circulation to find a blood congestion or clot. With this he can confirm the diagnosis.
D-dimer test
It is a blood test that reacts to breakdown products that are present when a blood clot breaks down. If the result is negative, DVT can be ruled out.
Venography
A venography enables the doctor to image the veins in order to identify diseases, blood clots or dangerous processes. For this specific x-ray of the veins, the patient receives a contrast medium with which the veins can be clearly displayed.
Magnetic resonance imaging (MRI) and computed tomography (CT)
With these two imaging techniques, the doctor can confirm the diagnosis and observe the blood clot in the veins. However, this method is rarely used to diagnose DVT.
Deep vein thrombosis: prevention
In preventive care, it is particularly important to avoid possible risk factors. These include tobacco and alcohol. It is also essential to regulate high blood pressure. Prevention consists in improving blood flow.
Your doctor will give you a variety of recommendations, including healthier lifestyle choices.
Generally, elevation of the legs is recommended to improve blood flow. For example, you can use pillows under your legs to raise them up while you sleep.
It is fundamental for smokers to get rid of this vice. Tobacco is a risk factor for numerous diseases, so there will be many benefits to you if you stop using it. In addition, exercise is fundamental! You should exercise for at least half an hour three days a week.
If necessary , the doctor will prescribe anticoagulants to prevent further discomfort. Get a thorough examination and follow your doctor’s instructions.
