Ovarian Remnant Syndrome Flashcards
What are the diagnostic options that we have for vulvar bleeding in an otherwise spayed female?
- Vaginal Cytology
- Hormonal testing
- Abdominal Ultrasound
What is the least expensive method of diagnosing estrogen exposure in the bitch?
Vaginal Cytology
What does it mean if you are seeing completely cornified cells?
That is an indication of a female that is in heat
What are the ways that a Bitch can be exposed to estrogen?
- Ovarian source
- Source of her adrenal glands
- Someone in the household using medication that contains estrogen
When you see signs of estrus in a previously spayed female, this is known as _____________________. In the bitch, it will include vulvar swelling and discharge. The queen and the bitch will be attractive to males. Mammary development and the queen will have lordosis/vocalization.
Ovarian Remnant Syndrome
(T/F) Ovarian Remnant Syndrome signs can show up anywhere from 7 days to 10 years post-spay surgery
True
What is the most common differential that we need to rule out?
Exogenous estrogen exposure
(T/F) Ovarian Remnant Syndrome is more common in small breed dogs
False
(T/F) It is usually going to be the right pedicle that is left behind because the right ovary is located further cranial than the left ovary
True
Progesterone only comes from the:
Ovary
(T/F) A value greater than 2 ng/ml indicates functional CL on the ovary
True
(T/F) In spayed animals, because of the lack of negative feedback from the ovaries, their LH test or luteinizing hormone test will always be negative
False, it will always be positive
Anti-Mullerian Hormone (AMH) is produced exclusively by the:
gonads
(T/F) The thing about the AMH test is that you have to worry about cross-reacting with adrenal hormones, sprays, or creams
False, you DON’T have to worry about cross-reacting
If the animal has a positive AMH, she has:
functional ovarian tissue
- This test is only accurate in post-pubertal animals
- You will get a qualitative result, a positive sample means they have an ovarian tissue
- Negative sample doesn’t necessarily mean that she doesn’t have an ovarian tissue
- Equivocal sample means that they are in a gray area
- It is recommended that if you get an equivocal or a negative sample to also submit a progesterone test
AMH test
How many days do you need to wait if you are concerned that you left ovarian tissue behind?
30 days post spay
A client brings you a dog that has continued to have bloody
vulvar discharge every 6 months following her spay cycle.
You are concerned about an ovarian remnant and submit a
profile for AMH and progesterone. The results you get are
as follows:
AMH-POSITIVE
Progesterone - 0.3 ng/ml
Based on this information, what are your thoughts?
This dog has an ovarian remnant
