简要总结
This study employs a propensity score-matched analysis to compare the treatment outcomes, focusing on percentage volume reduction between the conventional multi-incision lymphaticovenous anastomosis (LVA) technique and the novel single groin incision LVA technique in patients with unilateral lower extremity lymphoedema.
详细描述
Lymphaticovenous anastomosis (LVA), a surgical technique that connects lymphatic vessels (LVs) to adjacent veins, has demonstrated efficacy in alleviating lymphedema by enabling the drainage of stagnant lymphatic fluid.
Conventional LVA treatment for lower extremity lymphoedema (LEL) has favored distal, multiple incisions in the lower leg due to the denser and more superficial distribution of LVs and recipient veins in the distal regions.
Based on the recent advancement in the understaning of lymphosomes and the role of antegrade lymph flow, a shift to more proximal LVA around the groin region for LEL could be theoretically advantagous, but its clinical efficacy compared to conventional distal LVA remains underexplored.
