A randomized trial comparing treatments for varicose veins

Area of Science:

• Vascular Surgery
• Minimally Invasive Procedures
• Comparative Effectiveness Research

Background:

• Varicose veins are commonly treated with ultrasound-guided foam sclerotherapy, endovenous laser ablation, or surgery.
• The comparative effectiveness and safety of these treatments for varicose veins are not well-established.

Purpose of the Study:

• To compare the outcomes of ultrasound-guided foam sclerotherapy, endovenous laser ablation, and surgical treatment for primary varicose veins.
• To evaluate disease-specific and generic quality of life, complications, and clinical success rates at 6 months post-treatment.

Main Methods:

• A randomized trial involving 798 participants with primary varicose veins across 11 UK centers.
• Primary outcomes included disease-specific and generic quality of life using validated scales.
• Secondary outcomes assessed procedural complications, serious adverse events, and clinical success, including saphenous vein ablation rates.

Main Results:

• Disease-specific quality of life was slightly worse after foam sclerotherapy compared to surgery (P=0.006), but similar between laser and surgery groups.
• No significant differences in generic quality of life were observed among the three treatment groups.
• Procedural complications were lower in the laser group (1%) compared to foam (6%) and surgery (7%) (P<0.001); saphenous vein ablation rates were lower with foam sclerotherapy than surgery (P<0.001).

Conclusions:

• Quality of life outcomes were generally comparable across foam sclerotherapy, laser ablation, and surgery for varicose veins.
• Laser ablation demonstrated a lower frequency of complications.
• Foam sclerotherapy resulted in lower saphenous vein ablation rates, despite similar overall clinical efficacy and quality of life compared to surgery.
