Preliminary report of a thoracic duct-to-pulmonary vein lymphovenous anastomosis in swine: A novel technique and potential treatment for lymphatic failure

In brief

This preliminary study describes a novel surgical technique creating a direct connection between the thoracic duct and pulmonary vein in a swine model. The procedure aims to treat lymphatic failure conditions such as plastic bronchitis and protein-losing enteropathy in congenital heart disease patients by bypassing obstructed lymphatic pathways.

• Novel swine model demonstrates feasibility of thoracic duct-to-pulmonary vein anastomosis for lymphatic failure.
• Technique creates direct lymphovenous connection, potentially bypassing failed lymphatic drainage pathways.
• Proof-of-concept study may inform future surgical options for plastic bronchitis and protein-losing enteropathy.
• Animal model provides platform for refining anastomotic technique before clinical translation.
