|Abstract||An 18-month-old dog was examined because of ascites of 1 month's duration. Typical causes of ascites, including hepatic failure, heart failure, and protein-losing enteropathy, were ruled out. The dog's history included being hit by a car 6 months earlier, and the caudal vena cava had an S shape on thoracic radiographs. In addition, the abdominal fluid had a high protein concentration and low cellular content. These findings were all consistent with a diagnosis of postsinusoidal hypertension secondary to obstruction of hepatic venous outflow (Budd-Chiari-like syndrome). During exploratory thoracotomy, the pericardium appeared to have been torn from the heart and was partially wrapped around the caudal vena cava, causing a constriction. The pericardium was removed and the dog recovered without any further complications. Blunt trauma has been previously reported to cause kinking of the caudal vena cava and Budd-Chiari-like syndrome in dogs; but in these dogs, clinical signs of ascites developed a few days to several weeks after the traumatic incident. It appears that, depending on the cause of the hepatic venous outflow obstruction, onset of Budd-Chiari-like syndrome may be delayed for months.|
