The decision to offer surgical treatment for varicose veins should be based on objective evidence of venous dysfunction and not only the subjective appearance or the reported symptoms. Special tests are required to identify the sub-group of patients with functional superficial venous reflux accurately. The initial test should be simple, cheap, objective, sensitive and easy to perform by a wide range of staff in order to screen out patients without reflux. The final test should be anatomically specific to identify the appropriate surgical procedure. The aim of this study was to test the feasibility of using photoplethysmography (PPG) as the initial test as part of a one-stop vascular clinic assessment protocol.
