| Abstract: | Chylothorax associated with congestive cardiomypathy was diagnosed in a 10-year-old male castrated domestic shorthair cat via analysis of pleural fluid. The triglyceride concentration in the pleural fluid was high (579 mg/dl), compared with that in serum (87 mg/dl), and the fluid cleared with ether. Evidence of atrial and left ventricular enlargement was found via electrocardiography and thoracic radiography. Left-sided cardiac dilatation and reduced systolic motion of the left ventricle were revealed by echocardiography. The cat was treated with digoxin, furosemide, and aspirin. Two months after initiation of treatment, fluid (265 ml) was aspirated from the pleural cavity. Two months after this procedure, the cat was doing well, with minimal pleural fluid production. |
