2499. A pyometra-spayed dog still comes on heat?

Jul 18, 2015

On Jul 17, I got a sms asking me how much I charge for ermoval of ovarian remnant and whether the dog needed to be hospitalised? I replied that I needed more information than before giving a quotation as every surgical case is different in complexity. So, it would be better to talk on the phone. The owner phoned and the following were some information.

A 7-year-old female Miniature Schnauzer with pyometra had been spayed by Vet 1 on "May 2015".  The owner went to Vet 2 whose Jul 16, 2015 ultrasound of the ovaries and uterus showed a 6-cm  left ovarian remnant caudal to the left kidney. Biopsy and histology of the removed ovary, ovarian remnant or if no visible ovarian remnant of the ovarian pedicle is advised. 

No distinct stump pyometra is visible between the colon and bladder. It could be small and difficult to identify. Both uterus were not present as the dog was spayed in "May 2014".  

The owner had said that this dog came into heat in February and August regularly and had just passed some bloody vaginal discharge on Jul 17, 2015.  Ultrasound was done on this day.


The owner had done her internet research, knowing about cytology to detect estrus, hormonal prevention of estrus and minimal invasive removal of the ovary.

An image of the swollen uterus and ovaries with clamps at the ovaries was available from Vet 1. It seemed that one clamp showed little of the ovarian tissues while the other clamp had the whole ovarian tissues being removed.

The image of the uterus and ovaries after spay did show one ovarian tissues clearly but the other ovarian tissues were obscured. The  the ultrasound and clinical signs of heat and lactation in Jun 2015, after the spay, pointed to the left ovarian tissues not being completely removed.
