What is effective care for varicose veins?

Area of Science:

• Vascular Surgery
• Medical Technology Assessment

Background:

• Varicose veins impact a significant portion of the Western population, increasing healthcare resource utilization.
• Minimally invasive treatments like endovenous thermal ablation, foam sclerotherapy, and cyanoacrylate glue ablation are increasingly used for varicose veins.
• Patient and physician preferences often drive treatment choices, lacking robust evidence for superiority among modalities.

Purpose of the Study:

• To evaluate the effectiveness and cost-effectiveness of various minimally invasive treatments for varicose veins.
• To clarify appropriate outcome measures for varicose vein treatment beyond technical success.
• To assess the long-term quality of life and recurrence rates associated with different varicose vein therapies.

Main Methods:

• Comparative analysis of technical outcomes (e.g., saphenous vein closure rates) and clinical outcomes (symptoms, quality of life, recurrence).
• Review of existing data on endovenous thermal ablation, foam sclerotherapy, mechanicochemical ablation, and cyanoacrylate glue ablation.
• Cost-effectiveness modeling based on initial treatment costs and long-term outcomes.

Main Results:

• Technical outcomes like closure rates poorly correlate with symptom improvement, quality of life, or recurrence risk.
• No substantial differences in late quality of life measures were found between treatment modalities.
• Ultrasound-guided foam sclerotherapy appears most cost-effective in many models, though cost estimates have uncertainty.

Conclusions:

• Current minimally invasive varicose vein treatments offer similar long-term efficacy regarding quality of life and recurrence.
• Cost-effectiveness is primarily influenced by initial treatment costs, favoring ultrasound-guided foam sclerotherapy.
• The role and necessity of adjuncts and post-procedural care for varicose veins require further critical evaluation.
