Understanding Deep Vein Thrombosis (DVT) in Legs

Deep vein thrombosis (DVT) is a serious medical condition characterized by the formation of blood clots in the deep veins, most commonly occurring in the legs. These clots can pose significant health risks, potentially leading to life-threatening complications if left untreated. To fully grasp the importance of recognizing and addressing DVT, it’s crucial to understand its underlying mechanisms, symptoms, and available treatment options.

What Exactly is Deep Vein Thrombosis?

DVT occurs when a blood clot, also known as a thrombus, forms in one of the body’s deep veins. While these clots can develop in various parts of the body, they are most frequently found in the legs. The danger lies not only in the clot’s presence but also in its potential to break off and travel through the bloodstream, potentially causing a pulmonary embolism (PE) if it reaches the lungs.

Healthcare professionals often use the term venous thromboembolism (VTE) to encompass both DVT and PE, recognizing their close relationship in terms of prevention, diagnosis, and treatment strategies.

The Mechanism Behind DVT Formation

Understanding how DVT forms is crucial for recognizing risk factors and implementing preventive measures. The deep veins in our legs play a vital role in circulating blood back to the heart. This process is facilitated by the contraction and relaxation of leg muscles, which effectively squeeze blood through the veins. One-way valves within these veins ensure that blood flows in the correct direction, preventing backflow.

How Does Blood Flow Contribute to Clot Formation?

When blood flow in the veins slows down significantly, it can begin to pool. This stagnation creates an environment conducive to clot formation. Factors that impede blood flow, damage the lining of blood vessels, or increase the blood’s tendency to clot can all contribute to the development of DVT.

Identifying Risk Factors for DVT

While DVT can affect anyone, certain factors significantly increase an individual’s risk of developing this condition. By recognizing these risk factors, both healthcare providers and individuals can take proactive steps to prevent DVT occurrence.

What are the Primary Risk Factors for DVT?

• Age: Individuals over 60 are at higher risk
• Obesity: Excess weight puts additional pressure on veins
• Immobility: Extended periods of inactivity, such as during long flights or hospital stays
• Recent surgery: Especially procedures involving the hip, knee, or abdomen
• Hormonal changes: Pregnancy, use of birth control pills, or hormone replacement therapy
• Smoking: Impairs blood flow and vessel health
• Medical conditions: Including cancer, heart disease, and inflammatory disorders
• Previous history of blood clots or family history of clotting disorders

Understanding these risk factors allows for targeted preventive measures and increased vigilance in high-risk individuals.

Recognizing the Symptoms of DVT

Identifying DVT symptoms early is crucial for timely intervention and prevention of complications. However, it’s important to note that DVT can sometimes occur without any noticeable symptoms, making awareness and regular check-ups essential for those at high risk.

What Are the Common Symptoms of DVT?

When symptoms do manifest, they often appear suddenly and are localized to the affected area, typically the calf or thigh in leg DVT cases. Common symptoms include:

• Pain or tenderness, often described as a deep muscle ache
• Swelling (edema) in the affected limb
• Warmth in the area of the clot
• Redness or discoloration of the skin
• Soreness or aching sensation
• Low-grade fever in some cases

It’s crucial to seek medical attention promptly if these symptoms are present, as early diagnosis and treatment can significantly improve outcomes and prevent complications.

Diagnostic Approaches for DVT

Accurate diagnosis of DVT is essential for initiating appropriate treatment and preventing potential complications. Healthcare providers employ various diagnostic tools and techniques to confirm the presence of DVT and assess its severity.

How is DVT Diagnosed?

The diagnostic process typically involves a combination of clinical assessment and specialized tests:

1. Physical Examination: The healthcare provider will assess symptoms and risk factors, examining the affected area for signs of swelling, tenderness, and discoloration.
2. Duplex Ultrasound: This non-invasive imaging technique is the most common diagnostic tool for DVT. It uses sound waves to visualize blood flow in the veins and can detect clots with high accuracy.
3. Blood Tests: Specific blood tests, such as D-dimer levels, can indicate the presence of blood clots in the body. While not definitive on their own, these tests can guide further diagnostic steps.
4. Venography: In some cases, a contrast dye may be injected into the veins to create detailed X-ray images, allowing for visualization of blood flow and potential clots.
5. CT or MRI Scans: These advanced imaging techniques may be used in complex cases or when assessing for clots in areas that are difficult to visualize with ultrasound.

Early and accurate diagnosis is crucial for implementing effective treatment strategies and preventing the progression of DVT to more severe conditions like pulmonary embolism.

Treatment Strategies for DVT

Once DVT is diagnosed, prompt and appropriate treatment is essential to manage the condition effectively and prevent complications. The treatment approach is tailored to each patient’s specific circumstances, taking into account the severity of the clot, overall health status, and risk factors.

What Are the Primary Treatment Options for DVT?

The main goals of DVT treatment are to prevent the clot from growing larger, stop it from breaking off and traveling to the lungs, and reduce the risk of recurrent clot formation. Common treatment strategies include:

1. Anticoagulant Medications (Blood Thinners): These are the cornerstone of DVT treatment. They don’t dissolve existing clots but prevent them from growing and reduce the risk of new clots forming. Common anticoagulants include:
   • Heparin (typically used for initial treatment)
   • Warfarin (for longer-term management)
   • Direct oral anticoagulants (DOACs) like rivaroxaban or apixaban
2. Thrombolytic Therapy: In severe cases or when there’s a high risk of complications, medications that dissolve blood clots (thrombolytics) may be administered. This approach carries a higher risk of bleeding and is typically reserved for critical situations.
3. Compression Stockings: These specially designed stockings apply pressure to the legs, promoting blood flow and reducing swelling. They’re often used in conjunction with anticoagulant therapy.
4. Inferior Vena Cava (IVC) Filters: In cases where anticoagulants are contraindicated or ineffective, a filter may be placed in the large vein (inferior vena cava) to prevent clots from traveling to the lungs.
5. Lifestyle Modifications: Patients are often advised to make changes such as increasing physical activity, maintaining a healthy weight, and quitting smoking to support treatment and prevent recurrence.

The duration of treatment can vary depending on the individual case, ranging from several months to long-term management for those at high risk of recurrence.

Complications and Long-term Outlook of DVT

While prompt diagnosis and treatment significantly improve outcomes for DVT patients, it’s crucial to understand the potential complications and long-term implications of this condition. Awareness of these aspects can motivate adherence to treatment plans and preventive measures.

What Are the Potential Complications of DVT?

The most serious immediate complication of DVT is pulmonary embolism (PE), where a part of the clot breaks off and travels to the lungs, potentially blocking blood flow. PE is a medical emergency that can be life-threatening if not treated promptly.

Other potential long-term complications include:

• Post-thrombotic syndrome (PTS): A chronic condition characterized by pain, swelling, and skin changes in the affected limb. It can develop in up to 50% of DVT patients within two years of the initial event.
• Chronic venous insufficiency: Damage to vein valves can lead to long-term circulation problems in the affected limb.
• Recurrent DVT: Patients who have had DVT are at increased risk of developing future clots.

What is the Long-term Outlook for DVT Patients?

With appropriate treatment and management, many DVT patients recover without significant long-term effects. However, the risk of recurrence necessitates ongoing vigilance and often long-term preventive measures. Factors influencing the long-term outlook include:

• The extent and location of the initial clot
• Promptness of diagnosis and treatment
• Adherence to prescribed treatments and lifestyle modifications
• Presence of underlying risk factors or medical conditions

Regular follow-up with healthcare providers is essential for monitoring recovery, adjusting treatments as necessary, and addressing any emerging complications.

Preventing DVT: Strategies for Risk Reduction

Prevention plays a crucial role in managing the risk of DVT, especially for individuals with known risk factors. By implementing certain lifestyle changes and preventive measures, the likelihood of developing DVT can be significantly reduced.

How Can the Risk of DVT be Minimized?

Several strategies can help lower the risk of developing DVT:

1. Stay Active: Regular physical activity, especially exercises that engage the leg muscles, promotes blood circulation and reduces the risk of clot formation.
2. Maintain a Healthy Weight: Obesity is a significant risk factor for DVT. Maintaining a healthy body weight through diet and exercise can lower this risk.
3. Stay Hydrated: Proper hydration helps maintain blood volume and reduces blood viscosity, lowering the risk of clot formation.
4. Avoid Prolonged Immobility: During long trips or periods of bed rest, take regular breaks to move around or perform simple leg exercises.
5. Use Compression Stockings: These can be particularly beneficial during long flights or for individuals with a history of circulation problems.
6. Manage Underlying Health Conditions: Effectively controlling conditions like heart disease or diabetes can reduce DVT risk.
7. Quit Smoking: Smoking negatively impacts blood circulation and vessel health, increasing DVT risk.
8. Be Aware of Medication Risks: Discuss the potential risks of hormonal medications, such as birth control pills or hormone replacement therapy, with a healthcare provider.

For individuals undergoing surgery or hospitalization, additional preventive measures may be implemented, such as early mobilization, the use of pneumatic compression devices, or prophylactic anticoagulation therapy.

When Should Professional Medical Advice be Sought?

While preventive measures are crucial, it’s equally important to recognize when to seek medical attention. Individuals should consult a healthcare provider if they:

• Experience sudden swelling, pain, or warmth in a limb, especially the leg
• Have known risk factors for DVT and are planning long trips or periods of immobility
• Are recovering from surgery or have been hospitalized and have concerns about DVT risk
• Have a family history of blood clotting disorders or previous DVT episodes

Early intervention and proper risk assessment by healthcare professionals can significantly improve outcomes and prevent the development of DVT or its complications.

What is deep vein thrombosis (DVT)?

Deep vein thrombosis (DVT) is a blood clot or thrombus in a deep
vein. These blood clots are most common in the leg. But they may occur in the arm
or other part of the body. Part of a clot, called an embolus, can break off and
travel to the lungs. This is a serious condition called pulmonary embolus (PE). A
PE can cut off blood flow to all or part of the lung. PE is an emergency and may
cause death.

Healthcare providers use the term venous thromboembolism (VTE) to
describe these 2 conditions, DVT and PE. They use the term VTE because the 2
conditions are very closely related. And because their prevention and treatment are
also closely related.

What causes deep vein thrombosis?

The deep veins of the legs are located in the muscles. These help
carry blood from the legs to the heart. When leg muscles contract and relax, blood
is squeezed through the veins back to the heart. One-way valves inside the veins
help keep the blood moving in the right direction. When blood moves too slowly, it
can collect (pool) in the veins. This makes a clot more likely to form.

Who is at risk for deep vein thrombosis?

Anyone can develop a blood clot. But certain factors may raise
your risk for one. Anything that slows blood flow, causes injuries to the lining of
a vein, or causes increases in blood clotting can make you more likely to have DVT.
You are at risk for DVT if you:

• Are overweight or obese
• Have a blood-clotting disorder
• Are older than age 60
• Had surgery
• Have spent a long period of time not moving, such as
  staying in the hospital or traveling on a long trip
• Take birth control pills or hormone replacement
  therapy
• Are paralyzed
• Are pregnant
• Smoke
• Have a central venous catheter (for example, in a large
  vein in the chest)

You are also at higher risk if you have certain diseases and
conditions, such as:

• Previous blood clot
• Varicose veins
• Heart problems, such as heart failure or heart
  attack
• Inflammatory bowel disease
• Lupus, an autoimmune system disease
• Cancer and some cancer treatments

What are the symptoms of deep vein thrombosis?

DVT may happen without symptoms. When symptoms do happen, they may
be sudden. They may appear around the site of the DVT, such as the calf or thigh.
You may have these common symptoms:

• Pain, especially deep in the muscle
• Swelling (edema)
• Soreness or aching
• Redness and warmth in the leg, arm, or other area
• Low-grade fever

These symptoms may mean that you have a blood clot. The symptoms
of a blood clot may also look like other health problems. Always see your healthcare
provider for a diagnosis.

How is deep vein thrombosis diagnosed?

Your healthcare provider will ask about your health history and do
a physical exam. You may also need these other tests:

• Duplex ultrasound. This
  procedure involves placing ultrasound gel on the affected area and then
  moving a handheld device across it. A picture of the blood flow is displayed
  on a screen. Duplex ultrasound is the most common test for DVT.
• Blood tests. Blood tests may
  be done to look for blood clotting and other problems.

How is deep vein thrombosis treated? 

Treatment will depend on your symptoms, age, and general health.
It will also depend on how severe the condition is.

The goals of treatment are:

• To prevent the clot from getting larger
• To stop the clot from traveling to your lungs
• To lower the chance of another blood clot forming

Treatment may include:

• Blood thinners (anticoagulant
  medicines).
  These medicines lower the ability of the blood to clot.
  They are a main treatment for DVT. These medicines may be given as a shot,
  through an IV (intravenous) line into a vein, or in pill form. The most common
  side effect of blood-thinning medicine is bleeding.
• Clot busters (fibrinolytics or
  thrombolytics).
  These medicines are used to break up clots.
• Inferior vena cava filter. In
  some cases, a filter is placed in the vena cava. This is the large vein that
  returns blood from the body to the heart. This filter prevents clots from
  reaching the heart and lungs.

What are possible complications of deep vein
thrombosis?

The possible complications of DVT are:

• Pulmonary embolus. This can cut
  off blood flow to all or part of the lung. PE may develop quickly. It’s a
  medical emergency and may cause death.
• Chronic venous insufficiency.
  This may happen after a blood clot in a leg vein. It means that a vein no longer
  works well. It’s a long-term condition where blood pools in the vein instead of
  flowing back to the heart. Pain and swelling in the leg are common symptoms.
• Post-thrombotic syndrome. This
  health problem may also happen after a blood clot in a leg vein. It may occur in
  the weeks or months following a DVT. It’s a long-term problem. It causes pain,
  swelling, and redness. Ulcers and sores can also develop. All these symptoms may
  make it hard to walk and take part in daily activities.

How can I help prevent deep vein thrombosis?

You can help prevent DVT with these steps:

• Take blood thinners, if your healthcare provider has
  prescribed them for you.
• Wiggle your toes and move your ankles if you sit or lie
  down for long periods of time.
• Walk. Get up and move as soon as possible after surgery
  or illness.
• Wear elastic or compression stockings, if your
  healthcare provider has prescribed them.

If you are in the hospital, your risk for blood clots increases.
Your healthcare provider may prescribe the use a sequential compression device (SCD)
or intermittent pneumatic compression (IPC). Special sleeves go around both legs.
They are attached to a device that applies gentle pressure to the legs. Remove the
sleeves so that you don’t trip or fall when you are walking, such as when you use
the bathroom or shower. Ask for help if you can’t remove and replace the
sleeves. 

When you travel and must sit for long periods of time, you can
lower your risk of a blood clot by: 

• Walking up and down the aisles (if traveling by plane or
  bus)
• Stopping about every hour and walking a little (if
  traveling by car)
• Moving your legs, ankles, and toes while sitting
• Wearing loose clothing
• Limiting the amount of alcohol you drink
• Drinking a lot of water and other healthy drinks
• Talking with your healthcare provider about a program of
  regular exercise
• Staying at a healthy weight
• Quitting smoking, if you smoke

When should I call my healthcare provider?

If you have symptoms that may indicate a
blood clot in the lungs, call 911 or get emergency help. Symptoms of a blood clot
in
the lungs include:

• Chest pain
• Trouble breathing
• Coughing (may cough up blood)
• A fast heartbeat
• Sweating
• Fainting

If you are taking blood thinners, report bruising or bleeding to
your healthcare provider right away or get medical care right away. Symptoms may
include: 

• Blood in the urine
• Bleeding with bowel movements
• A bloody nose
• Bleeding gums
• A cut that won’t stop bleeding
• Vaginal bleeding

Key points about deep vein thrombosis

• DVT is a blood clot or thrombus in a deep vein. These blood
  clots are most common in the leg. But they can develop in other parts of the
  body.
• When blood moves too slowly, it can pool in the veins. This
  makes a clot more likely to form.
• Some risk factors for DVT are being overweight, being older
  than age 60, and spending a long period of time not moving, such as while
  staying in a hospital.
• The symptoms of DVT are pain, swelling, and redness in the
  leg, arm, or other area.
• Treatment may include medicines such as blood thinners and
  clot busters.

What is deep vein thrombosis?

The blood supply of the leg is transported by arteries and veins. The arteries carry blood from the heart to the limbs; veins carry blood back to the heart. The leg contains superficial veins, which are close to the surface, and deep veins, which lie much deeper in the leg. Deep vein thrombosis (DVT) is a condition in which a blood clot (a blockage) forms in a deep vein. While these clots most commonly occur in the veins of the leg (the calf or thigh), they can also develop in other parts of the body.

DVT can be very dangerous and is considered a medical emergency. If the clot (also known as a thrombus) breaks loose and travels through the bloodstream, it can lodge in the lung. This blockage in the lung, called a pulmonary embolism, can make it difficult to breathe and may even cause death. Blood clots in the thigh are more likely to cause a pulmonary embolism than those in the calf.

Causes of DVT

Many factors can contribute to the formation of a DVT. The more risk factors a person has, the greater their risk of having a DVT. However, even people without these risk factors can form a DVT.

Signs and Symptoms of DVT in the Leg

Some people with DVT in the leg have either no warning signs at all or very vague symptoms. If any of the following warning signs or symptoms are present, it is important to see a doctor for evaluation:

• Swelling in the leg
• Pain in the calf or thigh
• Warmth and redness of the leg

Diagnosis

DVT can be difficult to diagnose, especially if the patient has no symptoms. Diagnosis is also challenging because of the similarities between symptoms of DVT and those of other conditions such as a pulled muscle, an infection, a clot in a superficial vein (thrombophlebitis), a fracture, and arthritis.

If DVT is suspected, the doctor will immediately send the patient to a vascular laboratory or a hospital for testing, which may include a blood test, Doppler ultrasound, venogram, MRI, or angiogram.

Treatment of DVT

If tests indicate a clot is present, the doctor will make a recommendation regarding treatment. Depending on the location of the clot, the patient may need hospitalization. Medical or surgical care will be managed by a team of physicians which may include a primary care physician, internist, vascular (blood vessel) surgeon, or hematologist (blood disease specialist).

Treatment may include:

• Medication. A blood-thinning medication is usually prescribed to help prevent additional clots from forming.
• Compression stockings. Wearing fitted hosiery decreases pain and swelling.
• Surgery. A surgical procedure performed by a vascular specialist may be required.

Complications of DVT

An early and extremely serious complication of DVT is a pulmonary embolism. A pulmonary embolism develops if the clot breaks loose and travels to the lung. Symptoms of a pulmonary embolism include:

• Shortness of breath
• Chest pain
• Coughing up blood
• A feeling of impending doom

A long-term consequence of DVT is damage to the vein from the clot. This damage often results in persistent swelling, pain and discoloration of the leg.

Preventative measures

For those who have risk factors for DVT, these strategies may reduce the likelihood of developing a blood clot:

• Take blood-thinning medication, if prescribed.
• Reduce risk factors that can be changed. For example, stop smoking and lose excess weight.
• During periods of prolonged immobility, such as on long trips.
• Exercise legs every 2 to 3 hours to get the blood flowing back to the heart. Walk up and down the aisle of a plane or train, rotate ankles while sitting, and take regular breaks on road trips.
• Stay hydrated by drinking plenty of fluids; avoid alcohol and caffeine.
• Consider wearing compression stockings.

Deep vein thrombosis (DVT) – SonoExpert

Deep vein thrombosis (phlebothrombosis) is a deadly disease.

Symptoms of deep vein thrombosis

• The patient’s complaints depend on the location of the thrombus and the degree of obstruction of the lumen of the vein.
• Deep vein thrombosis is characterized by edema and bluish discoloration of the leg with a minimally expressed pain syndrome, almost without a general reaction of the body: if it is present, it is manifested by a slight increase in body temperature, mild malaise and weakness.

Phlebothrombosis of the deep veins of the lower leg most often develops in patients who are on bed rest. The first signs of blood clots in the deep veins of the leg are often a feeling of heaviness in the legs and slight swelling. Despite the erased clinical picture, deep vein thromboses can come off and cause thromboembolism of the branches of the pulmonary arteries. With deep thrombosis, this occurs more often than with superficial thrombophlebitis.

Treatment of deep vein thrombosis at the Sonomed Clinic

Deep venous thrombosis (DVT) is most commonly treated conservatively with long-term antithrombotic therapy. We find out the cause of the formation of blood clots in deep veins by studying the genetic and other factors of thrombophilia.

We treat femoropopliteal thrombophlebitis with the threat of a thrombus rupture using the method of closed aspiration thrombectomy – removing the dangerous one through a vein puncture. Timely operation completely eliminates the risk of fatal complications.

We treat iliac-femoral thrombophlebitis (phlegmasia) using the innovative methods of Rotarex. In case of a threat of a thrombus detachment, we temporarily protect ourselves with a special balloon, which is removed immediately after the removal of the thrombus.

We perform long-term catheter thrombolysis to dissolve all blood clots in small veins. We will definitely eliminate the cause of thrombosis, if it is associated with a mechanical obstruction in the vein, by installing special stents

Complications of thrombophlebitis

004 – attachment of an infection to a thrombosed vein drastically worsens the patient’s condition. The temperature rises to 40 C, chills, sweating occur. The pain in my leg gets worse. A picture of severe sepsis (blood poisoning) gradually develops. Treatment is very complex and includes the use of powerful antibiotics, large operations to excise festering blood clots. Without active treatment, it can lead to the death of the patient.

Ascending thrombophlebitis — growth of a thrombus and inflammation in a vein to deep veins. Requires urgent surgical intervention on an outpatient or inpatient basis.

Thromboembolism in the pulmonary artery (PE) – detachment of a thrombus fragment from a vein and its transfer with the blood flow to the pulmonary arteries. Depending on the size of the thrombus, thromboembolism can proceed at lightning speed – death occurs in the first 30 minutes. A smaller thrombus does not kill immediately, but causes severe respiratory and circulatory disorders and requires treatment in intensive care.

Thromboembolism of small branches of the pulmonary arteries is accompanied by the development of pneumonia, chronic heart failure. Pulmonary embolism (PE) is a deadly complication of deep and superficial vein thrombophlebitis. When a blood clot breaks off, it settles in the pulmonary vessels, blocking the access of blood to the lungs. This causes severe cardiac and respiratory failure. In half of the cases, massive PE ends in death, in the survivors – severe heart failure.
Remember that pathologies of the joints or skeleton that are not detected in time can have very sad consequences for the child in the future.

It is important to note that orthopedic ailments in babies may be the result of a birth injury or diseases that the mother suffered during pregnancy; as well as the result of a lack of vitamins and minerals.

It is necessary to know that the development of the musculoskeletal system in children is very intensive, literally every day, so it is very important to pay special attention to the health of the spine and joints.

 La thrombosis venosa profunda (TVP) ocurre cuando se forma un coágulo de sangre (trombo) en una o más de las venas profundas del cuerpo, más comúnmente en las piernas. Esto puede causar dolor o hinchazón en las piernas, pero también puede ocurrir sin sintomas.
La TVP puede desarrollarse si tiene ciertas afecciones medicas que afectan la forma en
que se coagula la sangre, si está inactivo durante un período prolongado, por ejemplo, después de una cirugía o un accidente cuando está postrado en la cama. 
La thrombosis venosa profunda puede ser muy grave porque los coágulos de sangre en las venas pueden desprenderse, viajar a través del torrente sanguineo y alojarse en los pulmones, bloqueando el flujo sanguineo (embolia pulmonar).
Sintomas
Hinchazon en la pierna afectada.
Dolor en la pierna, que suele comenzar en la pantorrilla con una sensación de calambre.
Piel enrojecida o descolorida en la pierna.
Sensación de calor en la pierna afectada.
La thrombosis venosa profunda puede ocurrir sin ningún sintoma.
Es importante buscar atención médica si padece alguno de los sintomas anteriores,

Eine tiefe Venenthrombose (DVT) tritt auf, wenn sich in einer oder mehreren der tiefen Venen des Körpers, am häufigsten in den Beinen, ein Blutgerinnsel (Thrombus) bildet. Dies kann Beinschmerzen oder Schwellungen verursachen, aber auch ohne Symptome auftreten. Eine TVT kann sich entwickeln, wenn Sie unter bestimmten Erkrankungen leiden, die sich auf die Blutgerinnung auswirken, wenn Sie über einen längeren Zeitraum inaktiv sind, z. B. nach einer Operation or einem Unfall, wenn Sie bettlägerig sind. Eine tiefe Venenthrombose kann sehr schwerwiegend sein, da sich Blutgerinnsel in Ihren Venen lösen, durch Ihren Blutkreislauf wandern und sich in Ihrer Lunge festsetzen können, wodurch der Blutfluss blockiert wird (Lungenembolie).

Symptome:

• Schwellung im betroffenen Bein.
• Schmerzen im Bein, normalerweise beginnend in der Wade mit einem Krampfgefühl.
• Rote oder verfärbte Haut am Bein.
• Ein Gefühl von Warme im betroffenen Bein.

Eine tiefe Venenthrombose kann ohne Symptome auftreten.
