How this tool works
The Villalta scale, endorsed by the International Society on Thrombosis and Haemostasis for defining post-thrombotic syndrome, scores five symptoms (pain, cramps, heaviness, paresthesia, pruritus) and six signs (pretibial edema, skin induration, hyperpigmentation, redness, venous ectasia, pain on calf compression) from 0 (absent) to 3 (severe). A total of 5 or more, or the presence of a venous ulcer in the affected leg, establishes PTS; 5-9 is mild, 10-14 moderate, and 15 or more (or any ulcer) severe. Assessment is typically applied from about 3-6 months after the index DVT.
