Use of Rutin for Successful Management of Feline Idiopathic Chylothorax

Abstract

High-dose rutin (500 mg, TID, PO) was used for medical management of a case of feline idiopathic chylothorax. The amount of pleural effusion decreased after the initial treatment. Daily doses of rutin were increased from 1, 500 mg to 2, 000 mg at 29th day of treatment. Approximately 150 days later, no pleural effusion was observed; after about 450 days it was possible to discontinue rutin therapy. Two years after the initial presentation, the cat was free of clinical signs and pleural effusion. This suggests that high-dose rutin may be clinically useful for the treatment of feline idiopathic chylothorax.
