Fistulous Track Formation in the Flank Associated with Foreign Body Granuloma Formed at the Ovary Pedicle in a Dog

Abstract

An 8-year-old female border collie was presented for the fistula of the skin in the flank. Preoperative diagnostic imaging suggested the fistulous track was associated with the granuloma possibly caused by the ligature material used in ovariohysterectomy. Exploatory laparotomy revealed that the granuloma involved the left kidney and that the fistulous track was extended from the granuloma to the skin in the flank. Resection of the granuloma and partial nephrectomy resulted in a good outcome and the dog showed no recurrence. It was concluded that multifilament nonabsorbable suture materials should not be used in ovariohysterectomy to reduce the incidence of the fistulous track and granuloma.
