“…The rapid feline uterine involution may contribute to this lower prevalence. 9 Similar to the findings of Chatdarong et al in nonpregnant cats, 19 Ferretti et al reported that at days 14 and 28 postpartum, the uterus could still be identified ultrasonographically, with mean diameters of 0.62 cm and 0.47 cm, respectively. 5 However, the results of our study demonstrated that in this period (after postpartum day 6), the genital tract of a cat is available for a new pregnancy.…”

The morphological involution of the uterus completes, to a large extent, within the first 48 h postpartum in Van cats. A more detailed hormonal analysis would contribute greatly to the understanding of the physiological processes involved in this period. Although postpartum involution appeared complete by 5.60 ± 0.99 days after parturition in Van cats, histological verification of this finding is needed.

“…Total uterine diameter was defined as the serosal to serosal distance. 5,9 All measurements were taken as leading edge to leading edge. A decrease in the diameters and uterine content were considered the criteria for uterine involution.…”

“…Doppler ultrasound has also proved to be useful for the evaluation of uterine involution during feline puerperium (Blanco et al., ). Uterine artery blood flow progressively decreases during the first 25 days after parturition, which is associated with the two‐dimensional ultrasonographic regression of the organ (Blanco et al., ).…”

Contents The aim of this study was to compare uterine two‐dimensional and Doppler ultrasonographic parameters in queens suffering from pyometra from those in early pregnancy. Secondly, the effect of the presence of clinical signs of systemic illness on these parameters was also described. Fourteen post‐oestrous queens, with uterine luminal content in the absence of embryos were included. According to their outcome (pyometra surgery or parturition), the queens were retrospectively assigned to one of the following groups: Pyometra (PYO; n = 7) or pregnant (PRG; n = 7). In all the queens, two‐dimensional and Doppler ultrasound examinations of the uterus were performed. The presence or absence of clinical signs of systemic illness was recorded. The widest cross‐sectional diameter (UD), uterine wall thickness (WT), uterine lumen contents (LC) and uterine artery resistance index (RI) were measured. Uterine horn diameter was higher in PYO group than in PRG group (p < 0.05), while WT (p > 0.1) and LC (p = 0.09) did not differ between groups. Values of RI for PYO and PRG groups were 0.61 ± 0.03 vs 0.53 ± 0.09 (p < 0.05), respectively. PYO cats suffering from clinical signs of systemic illness showed larger UD than those without signs (p < 0.01). It is concluded that two‐dimensional and Doppler ultrasound might be useful to distinguish queens suffering from pyometra from those in early pregnancy. Secondly, the clinical signs of systemic illness were associated with a larger UD.

“…In the cat, two‐dimensional and pulsed wave Doppler ultrasonographic changes of uterine involution during normal feline puerperium have also been described. Uterine artery blood flow progressively decreased during the first 25 days after parturition, in accordance with its B‐mode regression (Blanco et al, ).…”

Ultrasonography is the imaging technology of choice for the evaluation of the reproduction system and pregnancy in both humans and animals. Today, ultrasound equipments are smaller, cheaper, and much more efficient. These upgrades, along with image digitization, have pushed ultrasound into the point-of-care setting. The most recent advances of different ultrasound techniques and their potential use in reproduction imaging of small animals are described in this review. 2 | DOPPLER The Doppler effect describes a change in the wavelength of energy transmitted as sound waves as a result of motion of their source or their receiver. The most commonly used indices to describe the waveform of the spectral Doppler are resistance index (RI): RI = (S−D)/S, systolic/diastolic (S/D) ratio: S/D and pulsatility index (PI): (S−D)/A
