(GP)
Overview
- Subcutaneous, permanently dilated veins ≥3 mm diameter when measured in a standing position; however, they may not be visible.
- Most commonly the superficial veins of the lower limbs (most commonly occur in the legs due to reflux in the great saphenous vein and small saphenous vein)
- Long Saphenous Vein ⇒ travels above medial malleolus and medial aspect of thigh
- Short Sapehnous Vein ⇒ originates from lateral malleolus
- Very common → affects up to 40% of the population, but not all are symptomatic
- Prevalence increases with age
- Risk Factors → increasing age, family history, female sex, increasing numbers of births, obesity, occupations with prolonged standing and deep vein thrombosis
- Elevated venous pressure → incompetence of venous valves → reflux of blood back into superficial veins → further elevation of venous pressure → formation of varicose veins
Making Diagnosis
Clinical Features:
- Dilated Tortuous Veins → with the patient standing, the skin is examined visually and by palpation for irregularities and bulges consistent with varicose veins
- Leg Fatigue or Aching → worse with prolonged standing
- Leg Cramps
- Restless Legs
- Swelling
- Skin Changes
- varicose eczema (also known as venous stasis)
- haemosiderin deposition → hyperpigmentation (brown skin)
- lipodermatosclerosis → hard/tight skin, then champagne bottle appearance of leg
- atrophie blanche → hypopigmentation
