Article Synopsis
- - The study focused on using ultrasonography techniques to examine how the uterus returns to its normal state (involution) after giving birth, conducting evaluations immediately after birth and every 48 hours for 30 days.
- - Findings showed that while the overall texture of the uterus remained consistent, echogenicity (brightness) increased and total uterine diameter significantly decreased, especially in the first few days postpartum.
- - This research is groundbreaking as it provides baseline data on the stiffness of the uterine wall in healthy ewes, which could help in early diagnosis of uterine problems during the postpartum period.
The aim of this study was to evaluate the blood flow of the uterine artery, fetal aorta and umbilical artery in the physiological pregnancy of sheep by means of pulsed Doppler throughout the gestational period. Thirty Santa Inês ewes weighing between 45.4±4.

Twenty-four ewes were included, and tissue stiffness of foetal lung, liver, kidney and placentome was measured beginning with 10th gestational week by qualitative-quantitative ARFI elastography. A total of 33 healthy lambs were born.

Twenty-four pregnant ewes were included in the study. Ultrasonography assessments were performed in B-mode, from the ninth gestational week until parturition.
