Patients with documented DVT extension into or toward the proximal veins during surveillance
•Patients considered by their clinician to be at risk of extension to the proximal veins. This includes patients with:
-Unprovoked DVT
-D-dimer >500 ng/mL
-Extensive thrombosis involving multiple veins (eg, >5 cm in length, >7 mm in diameter)
-Thrombosis close to the proximal veins
-Persistent/irreversible risk factors such as active cancer [25]
-Prior DVT or PE
-Prolonged immobility
-Inpatient status
-COVID-19
The best treatment of distal DVT is not clearly established.1
Distal DVT can either be treated with anticoagulation (medicines that help prevent blood clots), with or without additional use of compression stockings, or no medications can be given, and monitoring with repeat ultrasounds can be performed to see if the clots grow, which requires anticoagulation.
