“…CSP complicated with morbidly adherent placenta may have higher incidence than expected. Pathological finding suggested that placental localization in the cesarean scar was accompanied by abnormal placental attachment in most cases 5 . One hypothesis was that a relatively hypoxic environment in the endometrium and myometrium of cesarean scar might contribute to abnormalities of placentation 6 .…”

Cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy, which is a long‐term complication of cesarean section. Prompt and accurate diagnosis of CSP is important to decrease maternal mobility and mortality. However, it is difficult to make an early detection for CSP complicated with morbidly adherent placenta. Contrast‐enhanced ultrasound with the advantage in blood flow imaging is low‐cost, time‐saving, safe and more accessible in clinical practice. Here, we report a case with early detection of CSP with placenta increta by contrast‐enhanced ultrasound and its successful uterine‐sparing surgical management.

“…Traditionally, PAS is thought to occur as a consequence of a localized uterine injury (e.g., previous cesarean section [PCS]), which can result in locally defective decidualization/scarring and abnormal placental adherence in a subsequent pregnancy. (2,3) In the presence of a low-lying placenta (placenta previa) and 3 PCSs, a woman would have a 61% risk of PAS. (4) The development of PAS is a complex multifactorial process.…”

This article presents the results of surgical treatment of placenta accreta in 18 women with a previous cesarean delivery according to the data of the Departments of gynecology at the Yakutsk Republican Clinical Hospital and Republican Hospital #1 (National health center) of the Republic of Sakha (Yakutia) for the period of 2018-2019. The diagnosis of placenta accreta spectrum (PAS) was based on ultrasound findings and MRI data. Seventeen patients underwent metroplasty. In PAS disorders, metroplasty is fertility-preserving surgery with minimal blood loss both by the laparotomic and laparoscopic approaches.

Caesarean scar pregnancy is the implantation of fertilized eggs in the scar of the previous cesarean section in the lower uterus. It is a serious long-term complication after cesarean section. Ultrasound examination, as the first choice to evaluate cesarean scar pregnancy plays an important role in its diagnosis, treatment and follow-up. This study first tried to propose new ultrasound diagnostic indicators to distinguish cesarean scar pregnancy from non-scar pregnancy of the lower uterine cavity; Logistic regression analysis was used to screen for risk factors related to scar pregnancy bleeding, with a view to providing clinical ultrasound indicators to predict bleeding risk; Secondly, the use of contrast-enhanced ultrasound and three-dimensional ultrasound to observe the scar diverticulum of cesarean section more than six months after the different surgical treatments of scar pregnancy, and to evaluate whether surgical scar repair can improve the scar diverticulum. Finally, using ultrasound to predict the position of the embryonic placenta, the new type of scar pregnancy in cesarean section is divided into three types: anterior wall placenta, anterior wall posterior placenta and posterior wall placental. The three types of CSP have significant differences in the thickness of the muscular layer in the scar of the lower part of the anterior wall of the uterus, the blood flow in the scar of the lower part of the anterior wall of the uterus, the number of days of hospitalization, the treatment method, and the treatment effect, which indicate that the new type is used for the diagnosis of CSP. Treatment and prognosis evaluation have high clinical value, can be used to guide clinical work, and provide a new idea for clinical diagnosis and treatment.

Features of the pathogenesis of the placenta growing in the scar after cesarean section

Abstract: In most cases, placental localization in the scar after cesarean section is accompanied by abnormal placental attachment: placenta accreta, less frequently in combination with its ingrowth (placenta accreta/increta).
