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.
