Use of the Clinical, Etiologic, Anatomic, and Pathophysiologic classification and Venous Clinical Severity Score to establish a treatment plan for chronic venous disorders

Abstract

To be useful in clinical practice and in the evaluation of clinical therapies for chronic venous disorders, a measurement instrument should be objective, inclusive of all severities of venous disease, and rapidly performed by clinicians. The Clinical, Etiologic, Anatomic, and Pathophysiologic classification helps us identify the etiology, whether it is congenital, nonthrombotic, or post-thrombotic; anatomic segments involved, whether deep, superficial, or perforators; and pathophysiologic data, such as reflux or obstruction. The Venous Clinical Severity Score can be used to observe patients longitudinally, especially after interventions, although the total score is biased with regard to advanced disease, such as C4 through C6. To be able to predict progression of disease, more patient-validated instruments are needed. Physician-reported outcomes (the Venous Clinical Severity Score and the Clinical, Etiologic, Anatomic, and Pathophysiologic classification) in association with a patient-reported outcome may be the solution for the development of an ideal treatment plan.
