varicose veins
diagnoses

definition and etiology

definition:
dilated, tortuous superficial veins; usually of the lower limbs; due to incompetent valves

primary varicose veins: generally benign; occur without deep vein pathology
secondary varicose veins: occur as a result of obstruction and valvular incompetence of the deeper veins; a more serious condition

etiology:
Usually, the greater and lesser saphenous veins are affected. There is a familial component. Other risk factors include pregnancy, obesity, and sedentary or standing lifestyle or job. May also follow increased abdominal pressure from ascites or tumors.

signs and symptoms

signs and symptoms:
• cosmetic unsightliness of the legs: raised, dilated, tortuous channels
• worse standing: legs get heavy and fatigued
• better elevating legs
• varicose veins may be painful and worse during the menses
• edema

lab findings:
• (+) Trendelenburg test with tourniquets

course and prognosis

Generally, the condition is benign, although there are associated complications due to the stasis of blood, including stasis ulcers, superficial thrombophlebitis, or "blow-outs". Conventional treatment consists of support hosiery and injection sclerotherapy; surgery on the veins is occasionally performed.

differential diagnosis

• lumbar nerve root irritation
• osteoarthritis of the hip or knee
• arterial insufficiency
• diabetic or alcoholic neuropathy
