    Villalta Score for Post-thrombotic Syndrome (PTS)

    Stratifies severity of post-thrombotic syndrome in lower extremity DVT.

    INSTRUCTIONS

    Use in patients with lower extremity DVT. Note: all symptoms and signs refer to the affected leg.

    When to Use
    Pearls/Pitfalls
    Why Use

    • Use in patients with lower extremity signs and symptoms related to DVT (e.g. swelling, discoloration, ulceration) and clinical suspicion for post-thrombotic syndrome (PTS).

    • Should defer PTS diagnosis until after the acute DVT phase has passed (3–6 months).

    Venous ulceration indicates severe PTS and automatically confers a score of ≥15.

    PTS can be seen in up to half of patients with lower extremity DVT within 2 years. This score both diagnoses and grades severity of PTS.
