Gr. Lisciandro et al., AUTOMOBILE-INDUCED OBSTRUCTION OF THE INTRATHORACIC CAUDAL VENA-CAVA IN A DOG, Journal of Small Animal Practice, 36(8), 1995, pp. 368-372
A two-year-old labrador retriever was examined after a year's history
of persistent ascites and exercise intolerance that began shortly afte
r the dog was struck by an automobile. Contrast venography showed tort
uosity of the intrathoracic caudal vena cava with partial obstruction
caused by kinking of the vessel. Surgical resection of a fibrous conne
ctive band that was found to be tethering the intrathoracic vena cava
ventrally, creating a partial obstruction, was performed. A hypothesis
of the aetiology of this phenomenon is presented.
