not sure if you had also read it or not.
Conservative treatment is recommended initially for chylothorax not due to malignancy or infection. Pleural effusion should be removed from the chest by needle aspiration for diagnostic purposes and to relieve extreme dyspnea. An over-the-needle intravenous catheter 18-16 gauge is placed ventrally as the radiographs may indicate. A chest tube should be placed on one or both sides of the chest if adequate drainage is not possible from just one side. The chest tube is used for removing accumulating fluid and flushing with sterile saline solution. Heparin 150 U/L can be added to the solutions to prevent clot formation obstructing the tube. Chest lavage 3 times daily is continued until the fluid is clear and very little can be recovered (2-3 ml/kg/d). This usually takes from 5-10 days of therapy. A diet low in fat and high in carbohydrates is the initial therapeutic modality. Medium chain triglycerides (MCT oil) 1-2 ml/kg/d can supply the needed lipids and by pass the intestinal lymphatics. Hills R/D diet is a low fat diet.
Surgical intervention is recommended if conservative therapy fails to resolve the cylothorax after 14 days. Thoracic duct ligation combined with a pericardectomy is considered the definative treatment for chylothorax and is highly effective. Bilateral chest drains are left in place and flushed for 3-7 days after surgery. Rutin has been used to reduce the inflammation and fibrosis that accompanies chylothorax. Rutin is a benzopyrone compound extracted from the fruit of the Brazilian Fava D'Anta (Dimorphandra) tree. No significant toxicity of rutin has been reported but there are no studies confirming its benefits. Suggested dose is 500 mg/cat orally twice daily.
