Abstract

Background: This was the long-term follow-up of a previously reported randomized clinical trial comparing endovenous laser ablation (EVLA) with cryostripping for great saphenous varicose veins.

Methods: A total of 120 patients with great saphenous varicose veins were randomized 1:1 to EVLA or cryostripping. Principal outcome measures were freedom from incompetence or neovascularization on duplex imaging, and improvement in Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Severity Score (AVVSS) 5 years after treatment.

Results: Life-table analysis showed freedom from duplex-derived incompetence and neovascularization at 5 years in 62 (95 per cent confidence interval 50 to 76) per cent after EVLA and in 51 (39 to 66) per cent after cryostripping (P = 0.246). Neovascularization was more common after cryostripping, but incompetent tributaries were more common after EVLA. VCSS and AVVSS values improved significantly after treatment in both groups, and were maintained for 5 years, but with no significant difference between the groups.

Conclusion: In this study, no significant difference was demonstrated in late outcome after EVLA or cryostripping in patients with great saphenous varicose veins.
