ABSTRACT Five dogs with kinking of the intrathoracic caudal vena cava (CVC) were studied. One dog had neither clinical nor laboratory abnormalities associated with the kinked CVC, and the cause was unknown. The other four dogs had evidence of post‐sinusoidal obstruction of venous flow characterized by high protein ascites (modified transudate). Causes of the kinked CVC were automobile trauma (two dogs), cardiomegaly with ascites, and a large neoplastic lung mass. Surgical removal of the kinked caval segment was successful in the two dogs injured by automobiles. Medical therapy with a diuretic was associated with a decrease in ascites, straightening of the CVC, and improvement in clinical condition of the dog with cardiomegaly and ascites. Surgical removal of the neoplastic lung mass in one dog resulted in straightening of the CVC, but it later died of respiratory failure associated with pulmonary neoplasia.
