All treatments were efficacious. The technical failure rate was highest after foam sclerotherapy, but both radiofrequency ablation and foam were associated with a faster recovery and less postoperative pain than endovenous laser ablation and stripping.

This study suggests that the short-term efficacy and safety of EVL and HL/S are similar. Except for slightly increased postoperative pain and bruising in the HL/S group, no differences were found between the two treatment modalities. The treatments were equally safe and efficient in eliminating GSV reflux, alleviating symptoms and signs of GSV varicosities, and improving quality of life. Long-term outcomes, particularly with respect to recurrence rates, shall be investigated in future studies, including the continuation of the present.

Five-year follow-up of our randomized controlled trial comparing EVLA with open surgery in patients with GSV incompetence did not show any significant difference between the two groups in primary or secondary end points, perhaps because of the small sample size. EVLA seems to be a valid alternative to open surgery.

No abstract

No significant differences in clinical or ultrasound recurrences were found between EVLA and surgery groups. Our study also shows that similar improvements in clinical severity scores and quality of life were gained in both treatments.
