Deep Vein Thrombosis: Ultrasound Criteria & Diagnostic Skills for Healthcare Professionals

We would like to share with you some more facts on the diagnostic approach of DVT for the occasion of deep vein thrombosis awareness month , in more details the ultrasound criteria used to diagnose a DVT 🎗️

There are direct and indirect ultrasound criteria for the detection and characterisation of DVT.


Deep Vein Thrombosis: Ultrasound Criteria & Diagnostic Skills for Healthcare Professionals


It is of paramount importance that healthcare professionals managing patients with suspected DVT have some knowledge of ultrasound. Ideally, having just some basic skills to perform a three point compression ultrasound could allow to perform a first screening, in particular in areas with no dedicated scanning facilities, to identify those patients who may need a full ultrasound examination as at higher risk of having a DVT.

Furthermore, after an episode of DVT, some patients may experience post thrombotic syndrome which consists in the presence of chronic venous reflux within the deep veins and often presence of scarring thrombus. Ultrasound allows to determine the presence of deep venous reflux and dynamically assess both the deep and superficial venous system for the presence of venous reflux (see image below) and residual or recurrent thrombosis.

With the CUS approach, deep vein patency is only assessed in two or three venous territories (usually the common femoral vein, the popliteal vein, the femoral vein), while the WLUS provides a more extensive examination where the entire deep vein system of the leg is scanned from the common femoral vein to the distal veins.

A combination of all the three modes (B-mode, colour Doppler and pulsed wave Doppler) is usually used to diagnose a DVT when performing a WLUS while only B-mode is generally used in the CUS approach.
