Strangulating lipomas: One of the more common obstructions seen is something called a strangulating lipoma. Lipomas typically hang from a stalk, which makes them a ticking time bomb for colic – at some point in the horse’s life it can wrap itself around the small intestine, cutting off the blood supply and causing sudden, extreme signs of pain. This took our sweet Primo with no warning on March 26th. His vaulters and riders are devastated. Primo carried vaulters of all ages and abilities. We had 8 wonderful years with Primo and never imagined we would loose him so soon and so suddenly. Our vet bill from UC Davis Large Animal Hospital was $12,000 for the surgery we had hoped would save him.
