Lymphovenous bypass is a surgical procedure used to treat lymphedema, a condition where excess lymph fluid accumulates in the tissues, causing swelling. The surgery involves connecting lymphatic vessels directly to veins, bypassing the damaged or blocked areas of the lymphatic system to restore normal fluid drainage. This procedure is especially effective in patients with severe lymphedema that has not responded to conservative treatments such as compression therapy or manual lymphatic drainage.

Lymphovenous bypass helps reduce swelling, prevent infections, and improve the patient's overall quality of life by restoring normal circulation and lymphatic function.
