Overview of the Venous – DVT Bilateral
The Venous – DVT Bilateral scan is a duplex ultrasound examination of the deep veins in both legs, performed to detect or exclude deep vein thrombosis.
Deep vein thrombosis, or DVT, occurs when a blood clot develops within a deep vein, most commonly in the leg.
A clot can partly or completely obstruct venous blood flow.
The principal concern is that part of the clot can travel to the lungs and cause a pulmonary embolism.
Duplex ultrasound combines real-time imaging with Doppler assessment of blood flow and compression of the veins.
Normal deep veins usually collapse when gentle pressure is applied with the ultrasound probe.
A vein that does not compress normally can indicate thrombosis.
A bilateral examination evaluates both legs and may be appropriate when symptoms affect both sides, the location of symptoms is unclear or a clinician has requested bilateral assessment.
The service is provided as a home visit, bringing vascular ultrasound equipment directly to your London address.
What Does the Venous – DVT Bilateral Assess?
Common femoral veins
Assesses major proximal deep veins in both legs for compressibility and blood flow.
Femoral veins
Evaluates the deep venous system through the thighs.
Popliteal veins
Assesses deep veins behind both knees.
Calf deep veins
Relevant calf veins may be examined according to the vascular protocol.
Vein compressibility
Affected veins may fail to collapse normally under probe pressure.
Intraluminal thrombus
Visible clot material can sometimes be demonstrated directly.
Doppler blood flow
Blood-flow patterns can help identify obstruction or altered venous circulation.
Chronic post-thrombotic change
Residual scarring, wall thickening or reduced vein elasticity can sometimes be identified after a previous DVT.
Who May Benefit From the Venous – DVT Bilateral?
People with swelling affecting both legs where DVT requires exclusion - Bilateral imaging assesses both deep venous systems.
People with pain or tenderness in both calves or thighs - Duplex ultrasound can directly investigate deep veins.
People with significant DVT risk factors and bilateral symptoms - Recent surgery, immobility or previous thrombosis can increase risk.
People with a history of DVT in either leg - Bilateral assessment may identify current or chronic abnormalities.
People with unexplained bilateral lower-limb swelling - DVT is one of several causes that can require exclusion.
People referred for bilateral venous assessment - Both sides can be examined during one home appointment.
Symptoms and Reasons to Consider the Venous – DVT Bilateral
DVT can produce obvious symptoms, subtle symptoms or occasionally no symptoms.
New swelling of both legs with significant clot risk factors - Bilateral ultrasound can assess whether thrombosis is present.
Calf or thigh pain and tenderness - Deep-vein thrombosis can cause localised discomfort.
Leg warmth or redness - These can occur with thrombosis but are not specific to DVT.
Symptoms after surgery or hospitalisation - Reduced mobility can increase venous thromboembolism risk.
Symptoms after prolonged immobility or long-distance travel - Extended periods without movement can increase DVT risk.
Symptoms during pregnancy or after childbirth - Pregnancy and the postpartum period increase venous thrombosis risk.
A previous history of DVT or pulmonary embolism - Recurrence risk can be higher.
Chest pain, sudden shortness of breath, coughing blood, collapse or severe breathing difficulty can indicate pulmonary embolism and require emergency care.
Suspected DVT should be assessed promptly. A home service should not be used where waiting for the appointment would delay urgent assessment.
How to Prepare for the Venous – DVT Bilateral
Do not stop anticoagulant medication to prepare for a DVT ultrasound.
This is a home-visit vascular scan.
What Happens During the Venous – DVT Bilateral?
Is the Venous – DVT Bilateral Safe?
DVT ultrasound uses sound waves and does not expose you to ionising radiation.
It is non-invasive and does not require injections or contrast material.
Compression with the probe can feel uncomfortable if a leg is already painful or swollen.
The examination can be repeated where clinically required.

Confirm relevant history
Include recent surgery, travel, pregnancy, previous DVT and anticoagulant treatment.
Home ultrasound examination

Receive your report
The authorised vascular report is delivered securely.
When Will I Receive My Results?
The current reporting turnaround is approximately 1 day after the examination.
Because suspected DVT can require urgent treatment, significant findings should be acted upon promptly.
A confirmed acute DVT generally requires immediate clinical management rather than waiting for a routine follow-up appointment.
Understanding Your Venous – DVT Bilateral Results
A report showing no evidence of DVT means the veins examined were considered patent and appropriately compressible without ultrasound evidence of deep venous thrombosis.
An acute DVT result indicates a blood clot within one or more deep veins.
The location and extent of thrombosis are important because they influence management.
The scan can also show chronic or post-thrombotic changes from previous clotting.
A negative scan does not mean that every cause of leg swelling has been excluded.
Depending on symptoms and clinical probability, repeat ultrasound or additional investigation can sometimes be required.
What Can the Venous – DVT Bilateral Detect?
Acute DVT - New thrombus can be detected within deep veins.
Proximal DVT - Clots involving femoral or popliteal veins can be assessed.
Selected calf DVT - Distal deep veins can be examined according to protocol.
Venous obstruction - Impaired flow caused by thrombosis can be demonstrated.
Chronic post-thrombotic changes - Previous DVT can leave residual structural abnormalities.
Limitations of the Venous – DVT Bilateral
Not every cause of leg swelling is venous thrombosis - Heart, kidney, lymphatic and other conditions can also cause oedema.
Very early or technically difficult thrombosis can occasionally require repeat assessment - Clinical probability remains important.
Pelvic veins are not fully visualised with a standard leg ultrasound - Additional imaging can be required when proximal obstruction is suspected.
A negative scan does not assess pulmonary embolism - Chest symptoms require an emergency PE pathway.
Clinical assessment remains essential - DVT investigation is normally considered alongside symptoms and risk factors.
