Chronic Venous Insufficiency and Post Thrombotic Syndrome
Key Points
Skin changes range on a continuum from normal skin or mildly ectatic veins to severe stasis dermatitis and ulceration. Symptoms are more common with post-thrombotic syndrome and include heaviness, aching, and paresthesias. Diagnosis is based on inspection, but patients should have ultrasonography to rule out deep venous thrombosis. Treatment is with elevation and compression; medications and surgery are typically ineffective.
