Summary
Chronic venous insufficiency (CVI) causes leg swelling and skin damage due to venous hypertension. Treatment focuses on compression therapy, with surgery for severe cases.
Area of Science:
- Vascular Medicine
- Dermatology
Background:
- Chronic venous insufficiency (CVI) is a prevalent condition causing significant morbidity.
- It stems from venous hypertension in the extremities, leading to capillary and skin damage.
Purpose of the Study:
- To elucidate the pathophysiological mechanisms of CVI.
- To outline diagnostic and management strategies for CVI.
Main Methods:
- Review of existing literature on CVI pathophysiology and treatment.
- Clinical observation of CVI manifestations.
Main Results:
- Venous hypertension increases capillary pressure, trapping white blood cells.
- Activated leukocytes damage endothelium, increasing permeability and causing skin ischemia via fibrinogen leakage and fibrin cuff formation.
- Clinical diagnosis is typically straightforward due to evident manifestations.
Conclusions:
- Vascular compression therapy is the cornerstone of CVI management.
- Refractory CVI cases may necessitate a combined medical and surgical approach.
