US DOPPLER VENOUS LOWER LIMB - RIGHT

The ultrasound (US) Doppler Venous Right Lower Limb is a dedicated evaluation of blood flow within the veins and arteries supplying the right leg. This test is very useful in diagnosing DVT, venous insufficiency or blood clots in the veins.  

What is US Doppler Venous Right Lower Limb? 

US Doppler Venous Right Lower Limb is the application of Doppler ultrasound on the right leg veins to establish the level of blood flow in the veins. It assists in diagnosing blockages, clots within veins, or irregular patterns of blood flow due to venous disease. 

Types of US Doppler Venous Right Lower Limb  

• Continuous Wave Doppler: For rapid examination of blood flow. 
• Colour Doppler Imaging: Shows the blood, movement in real-time. 
• Spectral Doppler: The direction and speed of blood is measured. 

• Compressibility alongside flow of the vein 
• Any blood clots present 
• The valve of a vein’s function 
• Reflux of abnormal flow patterns

• Diagnostic imaging of deep vein thrombosis (DVT) 
• Assessment of chronic venous insufficiency 
• Evaluation of post-surgical venous procedures 
• Evaluation of leg swelling of indeterminate origin
