The Utility of Venous Doppler Ultrasound in COVID-19

COVID-19 infection has been associated with a high rate of thrombotic events, such as deep vein thrombosis (DVT) and acute pulmonary embolism.

Several studies report a high risk of DVT in COVID-19 critically ill patients with pneumonia despite adequate thromboprophylaxis and have suggested using anticoagulant therapy in the therapeutic range.


Increased incidence of thrombotic complications are seen in:

- Severe COVID-19

- Prolonged ICU stay

- Diabetics


Increased incidence of asymptomatic DVT (60.87%) has been noted, mostly in the infra-popliteal venous system, in COVID-19 patients (especially those with elevated D-Dimer and severe respiratory failure).


Colour doppler ultrasound allows detection of DVT in asymptomatic patients, adding a factor that may influence the anticoagulant therapy in these patients.


Colour doppler ultrasound is:

- Easily available

- Non-invasive

- Rapid - Results are almost immediately available


Venous doppler ultrasound can be a game-changer in COVID-19 patients at risk of thrombotic complications by helping physicians make appropriate anticoagulation therapy decisions.
