Surgery remains the traditional technique for treating varicose veins and requires a general anaesthetic. A 3cm incision is made in the groin and the connection between the main superficial vein in the thigh and the main deep vein is tied off. The superficial vein is then stripped out through an additional incision on the inside of the knee. In cases where the vein connection behind the knee is the cause of the varicose veins, an incision is made here to tie off this connection. Small veins below the knee are removed through further incisions (2mm in size). These are called ‘phlebectomies’ or ‘avulsions’.
Most conventional varicose vein operations are now done as day-case procedures and do not routinely require an overnight hospital stay. However, patients are required to wear support stockings for one week following surgery and a convalescence period of 1 to 2 weeks is usually needed.
