Ligation After Ovariohysterectomy : What Is Best ? Radioactive Cats : When Is It Safe to Go Home ?

Anecdotally, knots that encircle the pedicle twice or incorporate a knot on each side of the pedicle are superior to a simple square ligature when fat obscures the pedicle. In high volume spay/neuter clinics located in remote areas, a form of the Miller’s knot is common, as ovariohysterectomy candidates are often mature, overweight, pregnant, and/or have uterine disease. Although this study did not involve live animals, the findings supported the use of bilateral ligature techniques, and these options should be considered in private practice, especially for a larger patient.— Heather Troyer, DVM, DABVP, CVA
