One study found that with<unk> , recurrences was 18% rather than 35% with high ligation and stripping after 10 years follow-up. Patient symptoms at 10 years, however, did not differ. The<unk>  and the stripping methods are equivalent regarding recurrence of varicose veins, but the<unk>  may slightly reduce nerve injury and hematoma. The<unk>  is also equivalent to either radio frequency ablation or endovenous laser therapy regarding recurrence and side effects.
