Japanese Translation of Venous Severity Scoring (VSS) System

Abstract

To describe the severity of chronic venous disease or measure clinical outcomes quantitively, Venous Severity Scoring (VSS) System was developed in 2000 to supplement Clinical-Etiology-Anatomy-Pathophysiology Classification (CEAP) Classification which is a worldwide standard for describing the clinical features of chronic venous disease. VSS system consists of three parts; Venous Clinical Severity Score (VCSS), Venous Segmental Disease Score (VSDS), and Venous Disability Score (VDS). VCSS was revised in 2010 after clinical experiences and validations. VSS system covers various types of chronic venous diseases and treatments. International Committee of Japanese Society of Phlebology provided a translation of Japanese translation of VSS system.
