Sažetak
An unusual lymph vessel was found in a male dog of estimated age 5-6 years, probably a German shepherd and Rottweiler cross bred. At the level of the 11th right dorsal intercostal artery a common trunk arising from the cranial cisterna chyli divided into a very thin thoracic duct (ductus thoracicus) with a diameter of 1-2 mm and a much bigger lymphatic vessel with a diameter of 6 mm. The thoracic duct, very thin in its postcardiac segment, was situated in its normal anatomical position while the big lymphatic vessel extended cranially through the right mediastinum covered with the right mediastinal pleura (pleura mediastinalis dextra). It ran laterally to the origins of the right dorsal intercostal arteries, situated at the ventral border of the right azygos vein, the right surface of the oesophagus and the dorsal wall of the Sussdorff’ s cavity (cavum mediastini serosum). At the root of the right lung (radix pulmonis dextra) it crossed the ventral surface of the oesophagus, inclined to the left cranial medistinum and drained into the thoracic duct. We recognized this large lymphatic vessel and its unusual course as the accessory thoracic duct - an anatomical variation with its origin in the embryonic development of the thoracic duct.
