During a 7-year period, 237 patients were treated surgically at Tromsø Hospital for varices of the great saphenous vein. At follow-up (mean 7.5 years) the overall results were excellent in 30%, good in 47%, and poor in 21% of the patients. The recurrence rate of varicose veins was 47%. However, 50% of these patients had no symptoms or only minor symptoms, from the recurrence. 37 patients noticed the occurrence of troublesome varicose veins within one year after operation. At clinical reexamination it was found that in 32 of these patients the surgery had been inadequate. This probably explains the rapid recurrence.
