Need for perforating veins dissection in patients with primary varicose veins still remains a matter of discussion. There is no evidence supported this procedure. Aim — to compare long term results for high ligation, stripping and phlebectomy with and without dissection of perforating veins. Material and methods. We retrospectively analyzed data on 95 patients with varicose veins operated by high ligation and stripping of great saphenous vein with phlebectomy. The first group included 22 patients who underwent no perforating veins dissection. Follow up ranged from 36 to 76 months (Me 53). Second group included 73 patients who had additional dissection of calf perforating veins of the calf. With follow up period from 23 to 96 months (Me 49). Recurrence rate and quality of life assessed by questionnaires SF-36 and CIVIQ-20 were end-points. Results. Recurrence rate in the first group was 27%, in the second — 42% (p=0.224). Physical functioning of for SF-36 and CIVIQ-20 global were better in patients without perforating veins dissection. To exclude differences between groups by sex and duration of observation we made matching, composing two equal groups with no differences. In matched patients recurrence rate was the same (27% in each group). Physical functioning remained better of patients who did not undergo a perforating vein dissection (p=0.039). At the same time, CIVIQ-20 global score turned out to be similar. Conclusions. Calf perforating veins dissection in patients with varicose veins does not improve long term results of high ligation and stripping of great saphenous vein with phlebectomy. Recurrence rate remains the same on those patients who underwent perforating veins dissection or not.
