Microsurgical bypass connecting blocked lymphatic channels to small veins — the gold-standard surgical treatment for limb lymphedema by Pune's only dedicated lymphedema surgeon.
LVA (Lymphaticovenular Anastomosis) is a supermicrosurgical procedure in which blocked or damaged lymphatic vessels are directly connected to nearby small veins using sutures finer than a human hair — under a high-magnification surgical microscope. This creates a bypass that allows excess lymph fluid to drain through the venous system, reducing persistent limb swelling. It is most effective in early-to-moderate lymphedema (ISL Stage I–II) where functional lymphatic vessels are still present.
Limb circumference measurements, lymphoscintigraphy (lymphatic mapping) and ICG lymphography to confirm LVA candidacy and map functional lymphatics.
Bypass sites mapped preoperatively using ICG fluorescence imaging to identify the largest, most functional lymphatic channels.
Under general or local anaesthesia. Tiny incisions (1–2 cm) along the limb. Lymphatics and adjacent veins identified under microscope and joined with 10-0 or 11-0 monofilament sutures.
Day surgery or 1-night admission. Compression garment worn from day 1. CDT programme continued.
Measurable limb volume reduction begins at 3–6 months. Significant patients report reduced heaviness and cellulitis episodes within weeks.
LVA creates a bypass by joining existing lymphatics to veins — it works best in early lymphedema where functional lymphatics are still present. VLNT (Vascularised Lymph Node Transfer) transplants healthy lymph nodes from a donor site — used in more advanced lymphedema or when LVA has insufficient vessels to bypass.
In appropriately selected patients (Stage I–II lymphedema with patent lymphatics on mapping), LVA achieves measurable limb volume reduction in 70–85% of cases. Reduction in cellulitis frequency and improved quality of life are reported in the majority of patients.
LVA significantly reduces lymphedema and may reduce or eliminate dependence on compression garments in many patients. It does not cure the underlying lymphatic damage but creates a compensatory drainage pathway. CDT must be continued post-surgery.
Suitability requires lymphoscintigraphy and ICG imaging to confirm that functional lymphatic channels are present. Dr. Thusay assesses all patients with these investigations before recommending surgery.
Typically 4–8 bypass sites are created along the length of the limb to maximise drainage. The number depends on the available lymphatics identified on pre-operative mapping.
Yes — compression garments remain an important part of lymphedema management after LVA. However, many patients find they can use lower compression class garments and for fewer hours per day after successful surgery.
LVA is a supermicrosurgical procedure requiring specialised training and equipment. Dr. Thusay is currently the only surgeon in Pune performing LVA, and one of very few in Maharashtra.
Most patients are mobile on the day of surgery. A 1-night hospital stay is typical. Compression is worn from day 1. Most patients return to normal activity within 1 week. The full effect of LVA develops over 3–12 months.
