Percutaneous retrieval of a jugular catheter fragment from the pulmonary artery of a foal.

A 49-kg (107.8-lb) sexually intact male Arabian foal was evaluated at 3 days of age because of profuse watery diarrhea, anorexia, and signs of abdominal pain. Physical examination findings were unremarkable except for evidence of diarrhea. A catheter was placed in the right jugular vein for administration of antimicrobials and lactated Ringer's solution. The foal was discharged with instructions to the owner to continue antimicrobial administration and fluid therapy; at home, the owner inadvertently cut the catheter at the level of the hub during attempted removal, and the catheter fragment migrated distally in the jugular vein and subsequently lodged in the pulmonary artery. The foal was readmitted to the hospital for retrieval of the fragment, using a percutaneous retrieval technique. Catheter fragmentation is a well-recognized risk of catheterization in horses. Catheter fragments can be retrieved somewhat easily from the jugular vein; however, if the fragment migrates to the heart or pulmonary artery, imaging the fragment to locate and retrieve it can be difficult. Complications associated with catheter fragmentation include septicemia, endocarditis, lung abscesses, pulmonary embolism, dysrhythmias, cardiac perforation, pulmonary or caval thrombosis, and death. To our knowledge, this is the first report of successful retrieval of a catheter fragment from the pulmonary artery in a horse.
