[Lymph flow following ligation of the ductus thoracicus in dogs]

Already few hours after artificial occlusion of the thoracic duct of dogs different communications appear between the lymphatic and the venous system: 1. Lymphovenous communications in the cervical area leading to the right venous angle. 2. Lymphovenous communications at heart level leading to the right venous angle. These lymphovenous communications seem to be preformed anastomoses, which are opened by an increase of the intralymphatic pressure.
