Treatment of Leg Lymphedema with Drainage
The primary treatment for leg lymphedema with drainage is complex decongestive therapy (CDT), which must include manual lymphatic drainage, compression bandaging (20-30 mmHg minimum, 30-40 mmHg for severe disease), exercise, and meticulous skin care, with immediate referral to a certified lymphedema specialist being essential for optimal outcomes. 1, 2
Immediate Management Algorithm
Step 1: Assess for Active Infection
- If drainage is accompanied by erythema, warmth, or systemic symptoms, initiate antibiotics immediately with penicillinase-resistant penicillin, first-generation cephalosporin, or clindamycin/vancomycin for penicillin-allergic patients 3
- A 5-day antibiotic course is as effective as 10 days for uncomplicated cellulitis 3
- Elevate the affected limb to promote gravity drainage of edema and inflammatory substances 3
Step 2: Refer to Specialized Lymphedema Therapist
- Refer immediately to a physical therapist with lymphedema certification, occupational therapist with lymphedema training, or certified lymphedema specialist 1, 2
- Early intervention is critical as lymphedema may be reversible or more effectively managed with early physiotherapy 2
- Delayed treatment leads to progression and increased complications 1, 2
Core Treatment Components (Complex Decongestive Therapy)
Manual Lymphatic Drainage (MLD)
- This specialized massage technique stimulates lymph flow and is recommended as first-line treatment (Grade C evidence) 1
- MLD is particularly beneficial for patients with sensitivity to bandaging due to allergies or discomfort 1, 2
- Must be performed by appropriately trained specialists 2
Compression Therapy
- Compression is the most important treatment component - lymphedema cannot achieve sustained improvement without compression 4
- Use multilayer inelastic bandaging during the initial attack phase to reduce volume 4
- Minimum pressure of 20-30 mmHg is required, with 30-40 mmHg advised for more severe disease 1
- Transition to elastic compression stockings or sleeves during the maintenance phase 4
- High-pressure sequential external pneumatic compression (90-100 torr) has shown long-term efficacy with 90% of patients maintaining reduced limb girth 5
Skin Care
- Keep skin well-hydrated to prevent dryness and cracking, which serve as portals for bacterial entry 3
- Treat interdigital maceration and fungal infections to prevent cellulitis 3
- Keep nails short to minimize damage from scratching 3
- Diabetic-type skin care is essential to control recurrent inflammatory episodes 6
Exercise
- Supervised progressive resistance training is safe and may improve lymphedema symptoms 1, 2
- Aim for 150 minutes of moderate intensity activity weekly to maintain lymphatic flow 1
- Use compression garments during exercise if lymphedema is present 2
- Contrary to historical advice, complete avoidance of physical activity is not necessary 2
Three-Phase Treatment Approach
Phase 1: Attack/Initial Treatment
- Use complex decongestive therapy with multilayer inelastic bandaging and manual lymphatic drainage 4
- Goal is to reduce volume of lymphedema 4
- Measure limb perimeters or volumes objectively to evaluate effectiveness 4
Phase 2: Maintenance Phase
- Use elastic compression stockings or sleeves, possibly associated with MLD 4
- Continue skin care and exercises 4
- Goal is to maintain volume reduction achieved in Phase 1 4
Phase 3: Withdrawal Phase
- Gradual transition to self-management 4
- Annual evaluation is necessary to monitor for progression and adjust treatment 3
Prevention of Recurrent Infections
For patients with recurrent cellulitis/erysipelas:
- Monthly intramuscular benzathine penicillin 1.2 million units in adults 3
- Alternatively, oral prophylaxis with erythromycin 250 mg twice daily or penicillin V 1 g twice daily 3
- Provide patient-initiated therapy with oral antibiotics to reliable patients to start immediately at first signs of infection 3
Weight Management
- Weight loss is recommended for overweight or obese patients, as obesity is a significant risk factor for lymphedema development and can exacerbate existing lymphedema 1, 2
- Refer to a registered dietitian for weight management counseling 2
Critical Pitfalls to Avoid
- Do not use diuretics - they are generally ineffective for lymphedema management and physiologically unsound for pure lymphedema 1, 2, 6
- Do not delay treatment, as this leads to progression with increased dermal sclerosis, decreased joint mobility, and functional impairment 1, 2, 4
- Do not fail to treat infections promptly, as inadequate infection management significantly worsens lymphedema 1, 2
- Do not attempt treatment without specialized training - CDT must be delivered by trained specialists 2
Advanced Treatment Options
If conservative treatment is insufficient after adequate trial:
- Consider referral for microsurgical interventions, which have shown effectiveness when conservative approaches fail 1, 2
- Low-level laser therapy can be considered for reducing limb volume and improving quality of life (Grade C evidence) 1
- Circumferential suction-assisted lipectomy has shown promise for long-term relief in selected patients unresponsive to conservative therapy 7
