Abstract: Objective To investigate the efficacy of high ligation combined with endovenous laser treatment(EVLT) in greater saphenous vein varicosity.Methods The clinical data of 218 cases of greater saphenous vein varicosity who underwent high ligation combined with EVLT during July 2003 to July 2006 were retrospectively reviewed,and were compared with the 100 cases as control who were operated on with the common surgery during 1998 to 2002.Results All of the patients who underwent the EVLT had healing by first intention without infection.Among most of them the symptoms of lower extremity disappeared or were alleviated,no motion disturbance during one month postoperative followup.There were no deep venous thrombosis and deep vein injury among them.Conclusion High ligation combined with EVLT is advantageous in terms of less incision,minimal hemorrhage,shorter operation time,more rapid recovery and shorter hospitalization time compared with common operation.Further more the complication is decreased and the recurrence is lower.However it is still imperfect.
