Villalta Score for Post-Thrombotic Syndrome (PTS)

Description

Calculates the Villalta Score to diagnose and grade the severity of Post-Thrombotic Syndrome in patients with a history of Deep Vein Thrombosis (DVT). The score assesses 5 subjective symptoms and 6 objective clinical signs, each rated on a scale of 0 to 3. The presence of a venous ulcer automatically classifies the condition as severe.

                   redness, venous_ectasia, pain_on_calf_compression,
                   venous_ulcer_present)
