Introduction: The Venous Clinical Severity Score (VCSS) was designed to give more strength to CEAP classification and to provide a method for serial assessment particularly to CEAP clinical class 4 and class 6. Even though the VCSS has been very useful, several areas of deficiency are also noted over time. VCSS was again revised by American Venous Forum with an intention to improve the VCSS, and also by preserving its strengths. Aim of the Study: To Compare VSS system with CEAP system postoperatively in assessing the outcome of varicose veins surgery. Methodology: A Prospective Longitudinal Clinical Study done in 30 patients from November 2019 to June 2021in the Department of General Surgery, Narayana Medical College and Hospital, Nellore. Duplex ultrasound for each patient to assess the following CEAP clinical class, CEAP 18- point clinical score, VCSS, VDS. Patients were followed up in the post-operative period for 6 weeks and 6 months and CEAP class, CEAP score, VCSS score and VDS will be recorded to assess the venous outcome at 6 weeks, 6 months.
