Japanese Translation of Villalta SCale and EVALUATION of Post-thrombotic Syndrome

Abstract

The PTS (post-thrombotic syndrome) is a common long-term complication following acute deep vein thrombosis of the lower limbs. There is no single scale that can diagnose and evaluate PTS perfectly. Villalta scale was developed in 1994 as a disease-specific questionnaire to diagnose and classify severity of PTS. Considered reproducible and sensitive enough to reflect clinical changes, Villalta scale is widely accepted as the gold standard and has been used in many cohort studies and multicenter randomized trials. The International Society on Thrombosis and Haemostasis recommended use of Villalta scale for diagnosis and grading severity of PTS. On the other hand, Villalta scale may potentially lead to overdiagnosis, have inadequate diagnostic specificity, or not cover various typical patitent’s complaints, symptoms and signs of PTS patients completely. Although Villalta scale should be combined with other chronic venous insufficiency scoring systems and questionnaire, it is the most commonly used of PTS-specific scales. We herein report the Japanese translation of Villalta scale.
