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
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
- 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.
