Under standing what is venous disorder?
Varicose veins and chronic venous insufficiency (CVI) are common clinical conditions associated with impaired venous circulation causing discomfort, oedema and skin changes. Varicose veins and CVI can be summarized under the term "chronic venous disorders" which includes the full spectrum of morphological and functional abnormalities of the venous system.
- Contrary to the historical opinion that varicose veins are the sequelae of simple mechanical valve failure, there is a growing evidence that the pathophysiology of primary venous insufficiency is a complex process, reflecting an interplay between systemic dysregulation of connective tissue synthesis, mechanical forces of venous hypertension, and cellular inflammatory reaction.
- Key causes of CVI are untreated venous disease and varicose veins, consequences of deep venous thrombosis (DVT), and conditions resulting in venous hypertension, alterations in venous competence, and venous valve disruption (as seen after DVT).3 4
