Deep Vein Thrombosis (DVT) Examination
Deep Vein Thrombosis Examination
Deep Vein Thrombosis (DVT) examination is a medical assessment used to diagnose the presence of blood clots in the deep veins of the body, typically in the legs. DVT is a serious condition that occurs when a blood clot forms in a deep vein, usually in the lower extremities. If left untreated, these clots can break loose and travel to the lungs, causing a life-threatening condition known as pulmonary embolism.
Pathophysiology
Deep Vein Thrombosis (DVT) is a condition characterized by the formation of blood clots (thrombi) within the deep veins, typically in the legs. The pathophysiology of DVT involves a complex interplay of various factors that contribute to clot formation. The Virchow’s triad outlines the three major factors that predispose individuals to thrombosis, and these factors are central to the pathophysiology of DVT:
1. Venous Stasis (Blood flow reduced)
Impaired Blood Flow: Reduced or sluggish blood flow in the veins can lead to stasis, promoting clot formation.
Valve Dysfunction: Venous valves normally facilitate one-way blood flow towards the heart. If these valves become damaged or dysfunctional, blood can pool, increasing the risk of clot formation.
2. Endothelial Injury (Damage to vascular walls)
Vessel Wall Damage: Injury to the endothelial lining of blood vessels can trigger the activation of clotting factors and platelets.
Inflammatory Conditions: Inflammation, whether localized or systemic, can contribute to endothelial dysfunction and increase the risk of clot formation.
3. Hypercoagulability (Increased Blood Coagulation)
Increased Blood Coagulability: Conditions that promote excessive blood clotting or decrease the body’s ability to regulate clotting factors contribute to hypercoagulability.
Abnormal Blood Constituents: Abnormalities in blood constituents, such as elevated levels of clotting factors or reduced levels of natural anticoagulants, can contribute to a prothrombotic state.
Risk Factors
Several risk factors contribute to the development of Deep Vein Thrombosis (DVT). These factors can be categorised into the three main groups from Virchow’s triad:
1. Venous Stasis (Blood flow reduced)
Prolonged Immobility: Extended periods of immobility, such as long flights or bed rest due to illness or surgery.
Paralysis or Limited Mobility: Conditions that limit movement, such as paralysis or orthopaedic injuries, can increase the risk of DVT.
2. Endothelial Injury (Damage to vascular walls)
Surgery or Trauma: Any surgical procedure, especially those involving the lower extremities or pelvis, can cause endothelial damage.
Intravenous Catheters: The placement of central venous catheters or long-term intravenous lines can damage the blood vessel lining.
Inflammatory Conditions: Inflammatory disorders, such as vasculitis or systemic lupus erythematosus, can contribute to endothelial injury.
3. Hypercoagulability (Increased Blood Coagulation)
Genetic Factors: Inherited conditions that affect blood clotting, such as Factor V Leiden mutation or prothrombin gene mutation
Acquired Conditions: Certain medical conditions, such as cancer, autoimmune disorders, and liver disease, can lead to a hypercoagulable state
Hormonal Influences: Estrogen-containing medications, including oral contraceptives and hormone replacement therapy, can contribute to increased blood clotting.
Pregnancy and Postpartum Period: Pregnancy increases the risk of DVT due to hormonal changes and increased pressure on pelvic veins. The postpartum period is also associated with an elevated risk.
Other Factors
Age: The risk of DVT increases with age, particularly in individuals over 60.
Obesity: Excess body weight is associated with venous stasis and increased pressure on the veins, raising the risk of clot formation.
Smoking: Tobacco use can damage blood vessels and promote a prothrombotic state.
Previous DVT or Pulmonary Embolism: Individuals with a history of DVT or pulmonary embolism are at a higher risk of recurrence.

Clinical Features
Usual clinical signs of a Deep Vein Thrombosis (DVT) include:
Swelling:
Unilateral (one-sided) swelling is a frequent early sign of Deep Vein Thrombosis (DVT). It usually occurs in the affected leg and may involve the calf, ankle, or thigh.
Pain and Tenderness:
Pain or tenderness in the affected leg is a common symptom. The discomfort may be described as a cramping, aching, or sore sensation.
The pain may worsen with standing or walking and might be relieved by elevating the leg.
Redness and Warmth:
The skin over the affected area may appear reddish or have a warm feeling due to inflammation.
Peripheral Venous Distention:
Superficial veins, often near the surface of the skin, may become more visible or engorged.
Consider Pulmonary Embolism If:
– Tachycardia
– Sudden Onset of Shortness of Breath
– Chest Pain
– Haemoptysis
Examination
General Inspection
In the general inspection of a patient, it is important to assess risk factors for deep vein thrombosis. Key considerations include age (with an increased risk for those over 60), obesity, pregnancy, immobility, trauma, and relevant medications.
Clinical signs to look for include unilateral swelling, pain, or erythema (indicative of deep vein thrombosis) and shortness of breath (suggestive of pulmonary embolism).
Basic Observations
A set of basic observations should be carried out with special attention for:
Pulse
Assess radial pulse (link article) and evaluate rate, rhythm, and strength.
- Tachycardia may indicate a red flag for pulmonary embolism.
- Bounding pulse may indicate sepsis which can be a risk factor of Deep Vein Thrombosis.
- Thready pulse can indicate dehydration, another risk factor for Deep Vein Thrombosis.
Blood Pressure
Hypertension can be caused due to increased pain whereas Hypotension may indicate large or bilateral pulmonary embolism along with dehydration, a risk factor of Deep Vein Thrombosis (DVT).
Chest Inspection
When considering Deep Vein Thrombosis (DVT) diagnosis, look for:
- PICC lines
- Cardiac pacemakers
- Central Venous Catheters
All of which fall under endothelial injury which is a risk factor of Deep Vein Thrombosis (DVT).
Upper limbs should also be inspected for signs of Deep Vein Thrombosis (DVT) with engorgement of peripheral veins a particular sign of Deep Vein Thrombosis (DVT).
Legs – Inspect
Both legs need to be exposed to fully assess for Deep Vein Thrombosis (DVT).
Inspect and compare both legs for:
Oedema: Caused by the obstruction of venous return, leading to fluid accumulation due to increased hydrostatic pressure, forcing fluid out of the vessels.
Erythema: Resulting from blood pooling in the lower extremities.
Distended Peripheral Veins: Like other areas of the body, collateral pathways for blood flow may develop when major veins are blocked. Peripheral veins serve as a diversion around the obstruction, potentially appearing distended.
Ulcers: These also point towards venous insufficiency.
Varicose Veins: While not directly linked to Deep Vein Thrombosis (DVT), they could indicate venous insufficiency, a risk factor for Deep Vein Thrombosis (DVT).
Legs – Palpate
During palpation, it is essential to compare both legs, as deep vein thromboses (DVTs) are more likely to occur unilaterally.
Temperature
Evaluate the temperature of each leg by placing your hand along a minimum of three sites, either moving proximally or distally.
Warmth is a common indicator of Deep Vein Thrombosis (DVT), but it can also signify infection or inflammation, such as cellulitis.
Pitting Oedema
Examine the patient’s legs for pitting oedema through palpation. Apply pressure with your thumb, exerting a comfortable amount of force along bony prominences, progressing from the medial malleolus proximally along the tibia until no oedema is detected.
Pitting oedema manifests as a distinct imprint where pressure was applied, though it might not be readily apparent in milder cases. Run your fingers over the pressure points for a subtle dip.
Unilateral oedema should prompt suspicion of Deep Vein Thrombosis (DVT), while bilateral oedema requires consideration of alternative causes, such as heart failure.
Tenderness
Gently compress the calves in a proximal direction, verbally confirming any pain and observing the patient’s facial expressions for signs of discomfort.
Measurement
Estimate the circumference of each calf around 10cm below the tibial tuberosity. A clinically significant finding is noted if the difference between the two measurements exceeds approximately 3cm.
The Rule Of 3s can help in the consideration of Deep Vein Thrombosis (DVT):
– Bedridden for 3 days
– Surgery within the last 3 months
– Leg swelling at least 3cm larger than the other side.
Wells Score
If there is suspicion of a DVT, a two-level Wells score for Deep Vein Thrombosis (DVT) should be carried out. It’s crucial to note that some patients may exhibit no symptoms, underscoring the significance of considering their medical history as well.
A score of 1 or less indicates Deep Vein Thrombosis (DVT) unlikely.
A score of 2 or more indicates Deep Vein Thrombosis (DVT) likely.
Management
The prehospital management of Deep Vein Thrombosis (DVT) primarily focuses on stabilising the patient and preventing further complications.
Initial Assessment:
Prioritise ABCs
Assess the patient’s overall condition and vitals
Conduct the above examination for Deep Vein Thrombosis (DVT) and complete Wells Score
Supportive Measures:
Administer oxygen if the patient is hypoxic.
Consider intravenous (IV) access for potential medications and fluid administration.
Elevate the Leg:
Elevate the affected leg, if possible, to reduce swelling.
Analgesia:
Provide pain relief as needed, considering the patient’s pain threshold.
Avoid Compression:
Avoid applying direct compression on the affected area, as it may dislodge a clot.
Immobilisation:
Immobilise the affected limb to prevent further complications.
Transport to the Hospital:
Arrange for prompt transportation to the hospital, preferably one equipped with the necessary facilities for managing Deep Vein Thrombosis (DVT).
Communication:
Communicate with the receiving hospital about the suspected Deep Vein Thrombosis (DVT), providing relevant information on the patient’s condition, vital signs, and any interventions performed.
Considerations for High-Risk Patients:
High-risk patients, such as those with significant comorbidities or a history of Deep Vein Thrombosis (DVT), may require more urgent transportation and specialised care. Any red flags such as tachycardia, shortness of breath and chest pain which could suggest pulmonary embolism requires emergency transport to hospital with a pre-alert.
Hospital Treatment:
Once at hospital, a proximal leg vein doppler ultrasound should be requested within four hours and if positive for Deep Vein Thrombosis (DVT), treatment with anticoagulants should be commenced.
A D-dimer test may be considered but its important to acknowledge that the D-dimer test is sensitive but not specific. Elevated D-dimer can be caused from various of reasons unrelated to deep vein thrombosis.
Alternative Diagnosis
Deep vein thrombosis (DVT) shares some clinical features with other conditions, and a thorough evaluation is necessary to establish an accurate diagnosis. Here are some common differential diagnoses for Deep Vein Thrombosis (DVT):
Muscle Strain or Injury
Muscle strains or injuries can cause localized pain and swelling, which may be mistaken for DVT.
Cellulitis
Cellulitis is a bacterial skin infection that can lead to redness, warmth, and swelling. It may be differentiated from DVT by the absence of deep, calf tenderness.
Superficial Thrombophlebitis
Superficial thrombophlebitis involves blood clots in the superficial veins, causing redness, pain, and swelling. It usually affects veins close to the skin surface.
Lymphedema
Lymphedema is swelling that occurs due to the accumulation of lymph fluid. It can cause unilateral leg swelling but lacks the characteristic tenderness along the deep venous system.
Compartment Syndrome
Compartment syndrome occurs when there is increased pressure within a muscle compartment, leading to pain and swelling. It may require urgent medical attention.
Peripheral Arterial Disease
PAD involves the narrowing or blockage of arteries, leading to reduced blood flow. While it can cause pain and discomfort, it is different from the venous thrombosis seen in DVT.
Baker's Cyst
A Baker’s cyst is a fluid-filled swelling behind the knee, often associated with knee joint issues. It may cause pain and swelling, mimicking some DVT symptoms.
Ruptured Baker's Cyst
A ruptured Baker’s cyst can cause sudden pain and swelling in the calf, resembling DVT symptoms.
Arthritis
Inflammatory or degenerative arthritis can cause joint pain and swelling, which may be confused with DVT, especially when affecting the lower extremities.
Varicose Veins
Complications like superficial thrombophlebitis or venous stasis ulcers in individuals with varicose veins can mimic DVT symptoms.
Conclusion
Deep Vein Thrombosis (DVT) is a medical condition characterized by the formation of blood clots within the deep veins, typically in the legs. This serious condition can result from a variety of factors, including prolonged immobility, surgery, trauma, or underlying health issues.
Deep Vein Thrombosis (DVT) often manifests with symptoms such as pain, swelling, warmth, and tenderness in the affected limb, though it can also be asymptomatic. Timely diagnosis is crucial, relying on a combination of clinical assessment, doppler ultrasound, and D-dimer tests.
Management involves anticoagulant medications to prevent clot extension and formation. Deep Vein Thrombosis (DVT) poses a significant risk of complications, particularly pulmonary embolism, making early intervention vital.
Key Points
- DVT is blood clot formation in deep veins, often in the legs.
- Risk factors include immobility, surgery, and underlying health issues.
- Symptoms may include pain and swelling; some cases can be asymptomatic.
- Preventive measures and early intervention with anticoagulants are essential to prevent complications such as pulmonary embolism.
