The ovarian pedicle tie (OPT) is an efficient autoligation technique exclusively performed on the ovarian pedicle in feline spays as an alternative to ligation with suture. It’s performed in a similar manner as autoligation of the male feline cord. Based on our findings noted below, the ASPCA's research recommends that general veterinary practices consider its use:
Is as safe and possibly safer than traditional ovariohysterectomy (OVH) using sutures with a comparable risk of hemorrhaging (only 9 of 15,927 cats—0.12%—experienced a pedicle-related hemorrhage, and all were corrected intraoperatively without serious complication or death)
Is 30% faster when compared to the traditional OVH, allowing you to do more spays or perform other patient care
Has potential health benefits to the animal by reducing anesthetic time and its associated risk
Potentially lowers the risk of patient complications from foreign bodies (sutures)
Requires no special equipment
Relies on a tie that many veterinarians are already familiar with from neutering male cats and male puppies
