Comparison of the Conservative Therapy and Thoracic Duct Surgery for Feline Idiopathic Chylothorax
On September 19,2023,a male cat at the age of 1.5 years with polypnea and pleural effusion was referred to Qidian Hospital in Henan Province.Light pink and opaque chyle were observed through thoracentesis,which was finally determined as idiopathic chylothorax after examination by routine blood test,blood biochemistry test,serum amyloid A(SAA)detection,X-ray and cardiac ultrasound,as well as rapid detection of feline heart diseases and pleural effusion analysis.The conservative therapy including daily low-fat diet,oral rutin tablets and thoracentesis was firstly used,followed by thoracic duct ligation surgery.The pleural effusion continued to increase after the conservative therapy,but gradually reduced when routine symptomatic administration and pain management were conducted after surgery,and a favorable prognosis was observed during the follow-up for nearly 3 months.In conclusion,the case was effectively treated by thoracic duct ligation surgery rather than the conservative therapy.Based on the amount and duration of effusion after surgery,pain could be more effectively relieved to reduce any postoperative complications and speed up recovery,if a pericardiectomy could be used together.A reference was provided for the identification and diagnosis of feline idiopathic chylothorax and for the selection of a treatment method.
