Lymphatic Surgery

Lymphedema is a chronic and progressive condition caused by impaired lymphatic drainage, leading to fluid accumulation, swelling, skin thickening, and increased susceptibility to infection and fibrosis. It can be classified as:

  • Primary lymphedema, which is congenital or hereditary in origin
  • Secondary lymphedema, which develops following surgery, radiation, infection, or trauma

At Asan Medical Center, we have extensive experience in managing both primary and secondary lymphedema in patients of all ages. We treat a large number of domestic and international patients, including complex and refractory cases, enabling us to deliver individualized and evidence-based treatment with consistently excellent outcomes.

Genetic and Multidisciplinary Approach for Primary Lymphedema

For primary lymphedema, we collaborate closely with our Medical Genetics Team to investigate:

  • Hereditary lymphatic disorders, such as Milroy disease and Meige disease
  • Chromosomal abnormalities and gene mutations
  • Syndromic lymphedema and congenital lymphatic malformations

Through comprehensive genetic testing and counseling, we ensure accurate diagnosis and support long-term management, especially for pediatric and adolescent patients.

Surgical Strategies to Restore Lymphatic Flow

We provide a full range of surgical options, selected based on disease stage, anatomical findings, and lymphatic function:

  • Lymphaticovenous Anastomosis (LVA)

    A minimally invasive procedure that reroutes lymph fluid by connecting functional lymphatics to nearby veins. It is most effective in early-stage disease when lymphatic flow is preserved.

  • Lymph Node to Vein Anastomosis (LNVA)

    This procedures reconstructs lymphatic drainage in the presence of obstructed but viable lymph nodes, and is commonly used for lower limb cases.

  • Vascularized Lymph Node Transfer (VLNT)

    This procedure transplants healthy lymph nodes, typically from the groin or omentum, along with their blood supply to the affected limb, encouraging lymphangiogenesis and supporting immune function.

  • Liposuction

    For advanced lymphedema, circumferential liposuction removes fibroadipose tissue. In severe cases, it is combined with Charles procedure, preserving perforating vessels to maintain blood flow.

  • Biobridge

    A collagen scaffold inserted in targeted areas to guide the formation of new lymphatic channels. It is often used as part of a multimodal strategy with LVA or VLNT.
