What are the treatment options for varicose veins (varicose veins tx)?

Treatment Options for Varicose Veins

Endovenous thermal ablation is the current standard of care for treating varicose veins, having largely replaced surgery with high success rates (91-100% occlusion within 1 year) and significant improvement in quality of life. 1

Initial Assessment and Conservative Management

• Conservative management should be tried first, especially since insurance often requires documentation of failed conservative measures before approving interventional procedures:

  • Compression stockings (20-30 mmHg gradient)
  • Leg elevation
  • Regular exercise
  • Weight management if applicable
  • Avoiding prolonged standing
  • Activity modifications 1

• While compression has traditionally been recommended as initial therapy, recent evidence suggests it may not be effective for varicose veins without active or healed venous ulcers 2

• A trial of conservative management for 3 months is typically recommended before considering interventional treatments 1

Interventional Treatment Options

1. Endovenous Thermal Ablation

• First-line interventional treatment for saphenous veins and larger varicosities
• Types:
  • Endovenous laser ablation
  • Radiofrequency ablation
• Best for patients with documented venous insufficiency, reflux >500ms, and vein diameter ≥4.5mm 1
• Post-procedure compression therapy is recommended to optimize outcomes 1

2. Sclerotherapy

• Indicated for:

  • Spider veins (≤1 mm in diameter): Use 0.5% polidocanol 3
  • Reticular veins (1-3 mm in diameter): Use 1% polidocanol 3
  • Residual varicosities after primary reflux sources have been addressed 1

• Administration:

  • Use 0.1 to 0.3 mL per injection site
  • Maximum 10 mL per session
  • Post-treatment compression for 2-3 days for spider veins and 5-7 days for reticular veins 3
  • Treatments should be separated by 1-2 weeks if multiple sessions are needed 3

• Cautions:

  • Contraindicated in patients with known allergy to polidocanol and acute thromboembolic diseases 3
  • Monitor for potential adverse events including phlebitis, pigmentation, and rarely DVT 1

3. Surgery

• Historically was the most widely recommended option but has been largely replaced by less invasive techniques 2
• Modern surgical approaches include:
  • Ligation and stripping
  • Phlebectomy with multiple small incisions
  • Small incisions to reduce scarring and blood loss
  • Limited removal of superficial axial veins from groin to knee 2

Treatment Algorithm

1. For patients with symptomatic varicose veins:

   • Begin with 3-month trial of compression therapy (20-30 mmHg)
   • If symptoms persist, proceed to venous duplex ultrasound to assess reflux and vein diameter

2. For saphenous vein incompetence:

   • Endovenous thermal ablation is preferred first-line treatment
   • Post-procedure compression therapy for optimal outcomes

3. For residual varicosities after treating primary reflux:

   • Sclerotherapy for smaller veins
   • Phlebectomy for larger bulging varicosities

4. For spider veins and reticular veins:

   • Sclerotherapy with appropriate concentration (0.5% for spider veins, 1% for reticular veins)
   • External laser for telangiectasias

Post-Treatment Care

• Compression therapy after any intervention is essential:
  • After thermal ablation or surgery: Compression with >20 mmHg pressure 4
  • After sclerotherapy: Maintain compression for 2-3 days for spider veins and 5-7 days for reticular veins 3
  • Walking for 15-20 minutes immediately after treatment 3
  • Follow-up ultrasound to confirm successful vein closure 1

Important Considerations and Pitfalls

• Treatment sequence matters: Address primary reflux sources before treating residual varicosities 1
• Potential complications: Monitor for thrombosis, arterial embolism, tissue necrosis, and allergic reactions 3
• Contraindications: Avoid sclerosants in patients with known allergies to the agents or acute thromboembolic diseases 3
• Recurrence: Varicose veins may recur after treatment, requiring additional sessions or different approaches 5

By following this evidence-based approach to varicose vein treatment, clinicians can provide effective care that improves both symptoms and quality of life for patients with varicose veins.
