“…Vaginal cytology findings of a bitch with ORS are usually correlated with signs of prooestrus such as the existence of red blood cells, neutrophil granulocytes and intermedier cells (Post 1985). Anechoic or hypoechoic structures observed during the ultrasonic inspection around the kidney area indicate the existence of ovarian parenchyma in the follicular phase (Davidson and Baker 2009). The results obtained from the examination of the bitch in this case were consistent with the abovementioned findings.…”

ABSTRACT:A four-year-old cross-breed and neutered bitch weighing 24 kg, was presented with vaginal bleeding for one month and a vaginal mass identified two previously. An ovariohysterectomy operation was performed at two years of age; however, mating subsequently continued. Vaginal bleeding and an irregular-shaped, oedematous vaginal mass (12 × 9 × 7 cm) were detected on clinical examination. The bitch also exhibited leukocytosis and erythrocytopenia. Abundant erythrocytes together with neutrophils, lymphocytes, intermedier cells and transmissible venereal tumour cells were observed in vaginal cytology. Abdominal ultrasonography showed cystic ovarian tissue (2.42 × 1.36 cm) next to the right kidney. Chemotherapy was performed once a week for six weeks leading to a gradual declined in the size and oedema of the mass and to a stop in bleeding. Subsequently, the vaginal mass was extirpated and the ovarian remnant tissue was removed via laparotomy on the same day. The bitch was found to be healthy on examination four months later.

“…Certainty of detection of ovulation via definition of a post-ovulatory CL and hence precise determination of oestrous status by ultrasonography alone may be controversial as was supported by the current study [10,12]. The predictive value of ovarian volumes for determining cyclic activity in cheetahs was supported.…”

“…The uterine horns were categorised as being either cyclically active or inactive [6] and the average diameter of both horns and the presence of uterine oedema (associated with oestrogenisation) were compared retrospectively to the designated reproductive status of individual cheetahs to determine a difference in size between the cyclically active and inactive groups. Round, intra-ovarian visualized structures were classified as follicles if they were anechoic and had acoustic enhancement and as periovulatory structures which included late, luteinizing follicles or CH (slightly echogenic with minimal acoustic enhancement) and CL (slightly hyperechoic to the surrounding ovarian tissue with no acoustic enhancement) [10]. The location of the ovaries relative to the ipsilateral kidney and surrounding structures were recorded.…”

“…Based on the combination of vaginal cytology, SPC measurements and the observed ultrasonographic and laparoscopic ovarian structures, the cheetahs were categorised as being cyclically active (pro-oestrus or oestrus and dioestrus) or inactive (anoestrus) [10].…”

“…The utilization of ovarian imaging to observe changes in ovarian function in domestic felids is partially limited by the small size of the ovarian structures but has been reported as an adjunct to oestrous monitoring in non-domestic felids [5,6,8,[10][11][12][13]. Ultrasonography provides a non-invasive, practical and relatively uncomplicated means to rapidly assess reproductive status in both free-ranging and captive animals.…”

Ultrasonographic and laparoscopic evaluation of the reproductive tract in older captive female cheetahs (Acinonyx jubatus)

The study uniquely described the clinical value of trans-abdominal ultrasonography for monitoring features characterising the oestrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous and relatively aged (median: 11 and interquartile range: 9.25 -14 years) captive cheetahs resident on two sites in Namibia were assessed by trans-abdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualisation whilst performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations (SPC) defined the oestrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualised in the 21 cheetahs. The uterine body was difficult to visualise due to its intrapelvic location. Eleven of 19 uteri (58%) visualised showed endometrial oedema suggestive of oestrogenisation. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia (CEH). Paraovarian (PO) cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) were in pro-oestrus or oestrus; none in the luteal phase and 11 (52.4%) in anoestrus. Trans-abdominal ultrasound in combination with SPC and vaginal cytology was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable 1 proportion of this aged population showed ovarian activity and the prevalence of PO cysts was notable. A history of prior deslorelin treatment was not associated with either reproductive activity or uterine pathology
