SCLEROTHERAPY OR SURGERY AS TREATMENT FOR VARICOSE-VEINS - A PROSPECTIVE RANDOMIZED STUDY

Objective: To compare the long-term results following radical surgery or compression sclerotherapy (CST) of primary varicose veins. Design: Prospective, randomized study of 164 patients. The patients were assessed with clinical tests and foot volumetry, before the 6 months. 1, 3 and 5 years after treatment. Setting: Department of Surgery, University of Lund, Sweden. Patients: 164 patients referred to the clinic for treatment of symptomatic primary varicose veins. Eighty patients were randomized to surgery and 84 to CST. Interventions: Sclerotherapy was applied using the 'empty vein' technique followed by compression bandage for 6 weeks. The extent of surgery was determined by each patient's disease and included flush ligation of the long or short saphenous veins and subsequent stripping, ligation of incompetent perforating veins and resection of local varicosities. Main outcome measures: The recurrence rate of varicose veins and incompetence of perforators and saphenous veins. Results: Good results were achieved in both treatment groups immediately after the procedure, but the failures appeared earlier in the CST group and the number was higher compared with the surgery group. After 5 years only 10% of the operated patients were considered as treatment failures compared with 74% of the patients treated with CST. The clinical results were supported by the foot volumetry measurements. Conclusions: This study clearly indicates that patients with primary varicose veins and incompetent saphenous veins should be treated with surgery, and CST should be confined to local varicosities, isolated insufficient perforators or recurrences after adequate surgery.
