Plain-English summary
This study looked at cases in dogs and cats where a buildup of lymph fluid in the chest (called chylothorax) happened at the same time as a blood clot in a major vein near the heart (cranial vena cava thrombosis). The researchers found that having a special device placed in the neck vein was a common factor in these cases. In four pets studied, the blood clot was significant and extended from the neck to near the heart. After treatment, three of the four pets saw their chylothorax improve. This suggests that if a pet with a neck device shows sudden breathing problems, they should be checked for this specific issue.
Abstract
This study reviewed confirmed cases of concurrent chylothorax and cranial vena caval (CrVC) thrombosis in dogs and cats, and determined predisposing factors for the development of chylothorax associated with CrVC thrombosis. The extent and location of the thrombus, the treatment regime, and the outcome are described. In all 4 cases, implantation of a jugular device was a predisposing factor to thrombosis of the CrVC, and there was extensive thrombosis of the CrVC extending from at least 1 jugular vein to just cranial to the heart. Chylothorax resolved in 3 of the 4 cases after medical and/or surgical intervention. The development of chylothorax concurrently with thrombosis of the CrVC in dogs and cats is likely dependent on the extent and location of the thrombus. Veterinary patients with indwelling jugular devices that develop acute respiratory signs should be assessed for chylothorax associated with thrombosis of the CrVC.
