title: Anatomical variations in bovine thoracic ducts.
abstract: Gross anatomical observations of bovine thoracic duct pathways and the lymph-venous junctions revealed that 37% of these ducts connected to the left venous angle at one location, whereas the other terminal connected to other areas, such as the left internal jugular vein, the left subclavian vein and the right venous angle, at more than one location. The thoracic duct pathways were classified according to Adachi's classification as types III, VI and IX. The frequencies of types VI, IX and III were 76%, 15%, and 9%, respectively and 48% of cattle had more than one ring formation in the thoracic duct pathway. These findings demonstrate many anatomical variations in bovine thoracic duct pathways and lymph-venous junctions.
