Perform peripheral venous ultrasound to evaluate clinical signs or symptoms suggestive of acute or new-onset deep vein thrombosis (e.g., extremity swelling, tenderness, erythema).

Repeat or perform venous ultrasound for patients with known venous thrombosis who have a clinical change and where documented change in thrombus burden would alter management or therapy.
Perform venous ultrasound to evaluate postthrombotic (postphlebitic) syndrome in patients with symptoms consistent with PTS (e.g., chronic leg pain, heaviness, swelling, itching, or leg ulcers).
