Clinical DVT prediction scores (CURB-65 score of 3 to 5 or Padua prediction score greater than or equal to 4) and elevated D-dimer levels can help stratify COVID-19 patients at risk for DVT who should undergo diagnostic imaging.70 Compared to conventional venography, the diagnostic sensitivity and specificity of ultrasound (US) to detect proximal DVT using compression is 90% - 100% .71 Currently, extremity venous Doppler US for DVT is recommended for symptomatic patients; however, a routine screening examination in asymptomatic patients is not recommended.
