Condition
Peripheral Venous Disorders
Peripheral venous disorders are conditions in which the veins of the limbs fail to return blood efficiently to the heart.
Overview
Aetiology
Chronic Venous Insufficiency
Chronic venous insufficiency involves insufficient venous return, usually from the limbs, when the valves in the veins fail and blood pools in the lower legs. It may be mild or asymptomatic in early stages, but progresses to general limb discomfort and skin changes including stasis dermatitis, ulcers, and edema.
Postphlebitic Syndrome
Postphlebitic (post-thrombotic) syndrome occurs after a deep vein thrombosis has damaged the venous valves. It produces the same signs and symptoms as chronic venous insufficiency, including swelling, aching, and skin changes in the affected limb.
Presentation
Symptoms
Common symptoms include aching, heaviness, or fatigue in the legs that worsens with prolonged standing, swelling around the ankles, visible varicose veins, and itching. Over time the skin may become discolored, hardened, or develop ulcers, particularly around the inner ankle.
Assessment
Diagnostic Considerations
Diagnosis is based on clinical examination of the limb and is often supported by Doppler ultrasound to assess venous flow and valve function. More advanced stages, with marked skin changes or ulceration, indicate significant loss of venous integrity.
Assessment
Differential Diagnosis
- Chronic heart failure
Context
Comorbidities
- Skin ulceration and infection
- Deep Vein Thrombosis
