🦵 Villalta Score (Post-Thrombotic Syndrome)
UseWhen to use: follow-up after lower-extremity DVT to detect/grade PTS.
StrataUse serially to track severity and response to compression/intervention pathways.
LimitsWhen not to use: to diagnose acute DVT. · Pitfall: scoring acute post-thrombotic inflammation too early as chro… · Ulcer forces severe classification.

Methodology · worked example, guidelines & full notes
PTS threshold ≥ 5.
When to use
When to use: follow-up after lower-extremity DVT to detect/grade PTS.
How it works
Five symptoms + six signs (0–3 each). ≥ 5 = PTS; 5–9 mild, 10–14 moderate, ≥ 15 or ulcer = severe.
Key points
- PTS threshold ≥ 5.
- Ulcer = severe.
- Next: Wells DVT if acute recurrence suspected; compression/vascular pathways.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Frequently asked questions
- Does Villalta Score (Post-Thrombotic Syndrome) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Villalta Score (Post-Thrombotic Syndrome) calculated in practice? Can you show a worked example?
- Inputs: Pain Mild (1), Cramps Mild (1), Heaviness Mild (1), Paresthesia Mild (1), Pruritus Mild (1), Pretibial oedema Mild (1), Skin induration Mild (1), Hyperpigmentation Mild (1)… → Result: Villalta 11（Category: Moderate PTS (10–14), Ulcer: Absent） Inputs: Pain None (0), Cramps None (0), Heaviness None (0), Paresthesia None (0), Pruritus None (0), Pretibial oedema None (0), Skin induration None (0), Hyperpigmentation None (0)… → Result: Villalta 0（Category: No PTS (< 5), Ulcer: Absent）
