From the Guidelines
Management for chronic venous insufficiency involves a comprehensive approach combining lifestyle modifications, compression therapy, medications, and sometimes procedures, with the cornerstone of treatment being regular compression therapy using graduated compression stockings (20-30 mmHg or 30-40 mmHg for more severe cases) as recommended by the most recent study 1.
Key Components of Management
- Compression therapy: graduated compression stockings (20-30 mmHg or 30-40 mmHg for more severe cases) to be worn daily from morning to evening, as supported by 1 and 1
- Lifestyle modifications:
- Elevate legs above heart level for 30 minutes several times daily
- Regular exercise, particularly walking and calf muscle exercises, to improve calf muscle pump function, as suggested by 1
- Weight loss for overweight patients
- Medications: venoactive drugs such as micronized purified flavonoid fraction (Daflon 500 mg twice daily), horse chestnut seed extract (300 mg twice daily), or pentoxifylline (400 mg three times daily) to reduce symptoms, with evidence from 1 and 1
- Procedures: endovenous ablation, sclerotherapy, or surgical interventions for advanced cases, as discussed in 1, 1, and 1
Rationale for Recommendations
The recommended approach is based on the most recent and highest quality studies, including 1 and 1, which emphasize the importance of compression therapy and lifestyle modifications in managing chronic venous insufficiency. The use of venoactive drugs and procedures is also supported by the evidence, although the choice of specific treatment should be individualized based on patient preferences and disease severity. Overall, the goal of treatment is to improve venous return, reduce venous hypertension, decrease inflammation, and protect the microcirculation, thereby addressing the underlying pathophysiology of venous stasis and valvular incompetence.
From the Research
Management Options for Chronic Venous Insufficiency
- Compression therapy is a mainstay of treatment for chronic venous insufficiency (CVI), with the goal of reducing venous hypertension and promoting healing of venous ulcers 2
- Graduated compression therapy has been traditionally used, but recent studies have challenged this approach, suggesting that progressive compression may be as effective 3
- Compression therapy can be achieved through various methods, including static compression, specialized compression pumps, and manual lymphatic drainage 4
- Objectives of compression therapy include reducing swollen limbs, maintaining minimum size, and allowing patients to participate in their care 4
Treatment Modalities
- Pharmacologic agents, such as diuretics and topical steroid creams, can reduce swelling and pain in the short term, but offer no long-term treatment advantage 2
- Herbal supplements, such as horse chestnut seed extract, may reduce the inflammatory response to venous hypertension, but their efficacy, quality, and safety vary 2
- Endovascular and surgical techniques, including laser, radiofrequency ablation, and chemical foam sclerotherapy, can improve venous hemodynamics and promote healing of venous ulcers 2, 5
Adherence to Treatment
- Adherence to wearing graduated compression stockings is a significant issue, with a study finding that 44.2% of patients were non-adherent 6
- Reasons for non-adherence include financial constraints, pain, ignorance of the need to wear stockings, heat, and other factors 6
- The adherence rate to wearing compression stockings was found to be 55.8% in one study, highlighting the need for education and support to improve treatment outcomes 6
