Varicose veins.
Varicosities may be due to congenital weakness of the vein walls or valves, or may be secondary to deep thrombophlebitis. The latter leads to loss of valve competency in the communicating veins and transmission of relatively high pressures to the superficial system. Edema, thrombophlebitis and stasis dermatitis are common side effects. Adequate surgical therapy is successful in 90% of cases. Sclerosing agents are of limited use.
