Abstract

OBJECTIVE

To determine the rate of complications associated with the ovarian pedicle tie procedure in cats undergoing ovariohysterectomy and examine whether cat characteristics or surgeon experience level were associated with complications.

ANIMALS

15,927 cats that underwent ovariohysterectomy with the ovarian pedicle tie procedure between January 1, 2017, and December 31, 2018.

PROCEDURES

Data were extracted from electronic and paper medical records. Complications were coded by a veterinarian blinded to surgeon experience level. Complications (pedicle drop or tear, pedicle hemorrhage, and pedicle-related death) were summarized as counts and percentages. Univariate associations between cat characteristics (eg, age, weight, reproductive status, and ownership) and surgeon experience level (clinic veterinarian vs training veterinarian or veterinary student) and each outcome were estimated separately for veterinarian and student training clinics.

RESULTS

A pedicle drop or tear occurred in 0.3% (n = 49) of cats and was significantly more likely among veterinary students. Most (41/49 [84%]) pedicle drops and tears did not result in hemorrhage. Only 19 of 15,927 (0.12%) cats had pedicle-related hemorrhage, and in all instances, hemorrhage was corrected intraoperatively without serious complication or death. Cat characteristics and surgeon experience level were not related to pedicle hemorrhage.

CLINICAL RELEVANCE

Results support previous evidence that the ovarian pedicle tie procedure is safe in cats undergoing ovariohysterectomy when performed by experienced surgeons or novice surgeons under supervision. Given the reduced anesthetic time associated with the procedure, the ovarian pedicle tie should be considered an acceptable standard practice in all practice settings.
