This umbrella systematic review evaluated the effectiveness of lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT) for lower extremity lymphedema (LEL) by analyzing 26 systematic reviews and 14 meta-analyses. The study found that LVA and VLNT significantly reduced limb volume, with reductions ranging from 34.16% to 46.8%. Immediate lymphatic reconstruction (ILR) was associated with a 30.3% reduction in LEL risk post-surgery.
Key findings
- LVA reduced limb volume by 34.16% to 46.8% with follow-up from 1 month to 8 years.
- Postoperative cellulitis decreased by 2.1 episodes/year after VLNT.
- ILR reduced the risk of LEL by 30.3 per 100 patients treated compared to no ILR.
- Symptoms or quality of life improved in 50% to 100% of patients across 17 reviews.
Why it matters
Understanding the effectiveness of microsurgical options for lymphedema is crucial for clinicians to make informed decisions about patient management and treatment planning, particularly in advanced disease stages.
