Objective: To observe the early changes of uterine incision defects after cesarean section by transvaginal color Doppler ultrasound, and to analyze the risk factors of their formation. Methods: A total of 181 women who underwent cesarean section from September 2016 to June 2018 and who underwent transvaginal ultrasound examination at 6 weeks, 3 months, and 6 months after birth were divided into two groups. (142 cases) and incision defect group (39 cases). The incision changes and the risk factors of incision defect in different periods of postpartum were analyzed. Results: Compared with the group with good incision healing, the length of the incision defect in the cesarean section at 6 months after delivery was shorter than that at 6 weeks after delivery (P < 0.05). The results of non-conditional logistic regression showed that the number of cesarean sections increased and the number of operators was lower. Seniority, postoperative infection, posterior uterine position, and incision close to the cervix are risk factors for poor healing of uterine scars. Conclusion: As the postpartum time increases, the length of the cesarean section incision defect shortens; multiple cesarean sections, puerperal infections, posterior uterus, low incision position and inexperience of the operator are the risk factors for the formation of uterine incision defects and increase uterine scars. Risk of poor healing.

Objective To quantify the degree of change in cervical length (CL) over a 3-minute transvaginal ultrasound. Study Design We conducted a prospective observational study of nulliparous patients who underwent routine transvaginal CL screening at the time of their second-trimester ultrasound. We recorded CL at four time points (0, 1, 2, 3 minutes) and compared these values to determine the minute-to-minute change within a single patient. Results A total of 771 patients were included. The mean gestational age was 20.8 weeks (±0.84). We used a linear mixed effect model to assess if each minute during the ultrasound is associated with a change in CL. The intraclass correlation coefficient between minute 0 to minute 3 was 0.82 (95% confidence interval: 0.80, 0.84). This indicates that there is a relatively high within-patient correlation in CL during their ultrasound. Additionally, we stratified patients based on their starting CL; the intraclass correlation coefficient remained high for all groups. We additionally compared CL at each minute. Although there is a statistically significant difference between several time points, the actual difference is small and not clinically meaningful. Conclusion The variation in CL over a 3-minute transvaginal ultrasound examination is not clinically significant. It may be reasonable to conduct this examination over a shorter period.

Our statistical analysis, based on ultrasound examination of 7069 pregnant women, showed that both in the absence and in the presence of a scar on the uterus in the region of its lower segment, the placenta in the 3rd trimester of pregnancy was located extremely rarely, only in 0.1%. It was either primarily located in other parts of the uterus, or migrated from the lower segment of the uterus towards the bottom. In the case of the location of the placenta in this area, its ingrowth was not observed only in 2.3% of women. The main ultrasound signs of ingrowth of the placenta into the scar was the absence of its migration, as well as the presence of a combination of placenta previa with its localization in the scar zone. From the data obtained, it follows that the sensitivity of ultrasound diagnosis of placental accreta was 97.7%, and the specificity was 99.9%. According to our data, ingrown placenta in most cases can be delivered as early as 14–19 weeks, and the time spent on detecting this pathology usually does not exceed one minute.

ABSTRACT Cesarean scar defects (CSD) or niche are the myometrial discontinuity at the previous cesarean section scar region. Recently cesarean section delivery has been raised around the world markedly; therefore women with cesarean scar defects are increased and present in up to 19% of women post cesarean section. The increase of repeat cesarean section has been associated with an increase in complications in subsequent pregnancies such as scar pregnancy with life threatening bleeding, uterus rupture, placenta accreta and its subtypes and prolonged postmenstrual Spotting. The deeper the niche (or the thinner the overlying myometrium), the higher the risk for complications in a subsequent pregnancy. Although the ability of transvaginal ultrasound (TVUS) to detect cesarean scars remains unknown, its higher frequency and proximity to the pelvic organs have been used as a powerful tool for detecting the uterine scar of a previous cesarean section. Recently with the increasing use of sonohysterography (SHG) (transvaginal ultrasound with saline infusion) detection of scar defect has been enhanced frequently.
