“…Interestingly, pregnant women after IVF in this study had a lower incidence of placenta previa as well as previous cesarean births, which are the major risk factors for placenta accreta. 9 Ultimately, in addition to factors such as age, placenta previa, and previous cesarean section, IVF was found to be an additional independent risk factor for PAS. 10 The exact mechanism by which IVF may increase the incidence of PAS remains not fully understood, although there are a number of theories.…”

Placenta previa and related pregnancy complications are more common in In vitro fertilization pregnancies compared with spontaneous ones. There is evidence that PAS disorders are more common in pregnancies after IVF. Factors leading to a higher incidence of this pathology in IVF pregnancies have not been fully studied. Possible causes are the advanced age of women undergoing IVF, factors related to infertility itself, causes from the biological part of the In vitro procedure or controlled ovarian stimulation. The study of these factors is crucial for clinical practice as it would improve the outcome of IVF pregnancies.

“…13 One additional mechanism has been recently suggested in studies investigating the role of in vitro fertilization as a risk factor for PAS A characteristic hormonal milieu at the time of implantation and placentation resulting from IVF may enhance trophoblast invasion and cause PAS. 14 Aberrant placentation may be the effect of elevated serum estrogens at the time of embryo implantation, which may lead to excessive trophoblastic invasion through the endometrium. Alternatively, lower serum estradiol levels together with the presence of a thinner decidualized endometrium may result in abnormal trophoblastic growth leading to PAS.…”

“…27,28 Additional risk factors are advanced maternal age, high parity, IVF, and a diagnoses of PAS in a previous pregnancy. 14,15,29,30 However, the major risk factor for PAS is a prior cesarean delivery in combination with placenta previa, namely, a placenta implanting over the cervical os. Moreover, the risk of PAS increases progressively with increasing number of previous cesarean deliveries.…”

The worldwide incidence of placenta accreta spectrum (PAS) is rapidly increasing, following the trend of rising cesarean delivery. PAS is an heterogeneous condition associated with a high maternal morbidity and mortality rate, presenting unique challenges in its diagnosis and management. So far, the rarity of this condition, together with the absence of high quality evidence and the lack of a standardized approach in reporting PAS cases for the ultrasound, clinical, and pathologic diagnosis, represented the main challenges for a deep understanding of this condition. The study of the available management strategies of PAS has been hampered by the heterogeneity of the available epidemiological data on this condition. The aim of this review is to provide a critical view of the current available evidence on the screening, the diagnosis, and the management options for PAS disorders, with a special focus on the challenges we foresee for the near future.

“…Numerous researches were devoted to identify non-IVF is safer than IVF. For instance, the occurrence of subchorionic hematoma (23), ischemic placental disease (24), placenta accreta spectrum (25), and neonatal complications (26) was less likely to happen in non-IVF. Nevertheless, there is no denying that ART has been reported to be associated with some undesirable outcomes.…”

Background: More than 50 million women suffer from infertility worldwide, among whom 30% have associated fallopian tube pathology. Fortunately, the diagnostic accuracy of tubal patency has been enhanced with the consistent development of ultrasound imaging technology, especially the invention of transvaginal 4-dimensional hysterosalpingo-contrast sonography (TV 4D HyCoSy). However, detailed imaging data for evaluating the tubal condition for spontaneous conception and assessing the necessity of assisted reproductive technology (ART) have yet to be amassed.Methods: Patients with tubal factor infertility (TFI) who received TV 4D HyCoSy were recruited for this study. They were divided into two groups according to the method of conception: the natural pregnancy group (patients who naturally conceived within 3 months after TV 4D HyCoSy) and the assisted reproduction group (patients who failed to conceive naturally within the 3 months but successfully conceived through ART). Logistic regression analysis was performed to examine the data obtained from participants' medical history and TV 4D HyCoSy investigation.Results: Of the initial 1,433 women, 348 were excluded due to exclusion criteria or lack of follow-up. A total of 1,085 TFI patients were finally included, with individuals in the natural pregnancy group accounting for 27.74% (n=301), and those in the ART group accounting for 37.33% (n=405). The age was younger and the duration of infertility was shorter in the group of women who conceive spontaneously after TV 4D HyCoSy (P<0.05). In terms of imaging data, their endometrial thickness was thinner, right fallopian tube wall was more intact, morphology of the right fallopian tube was smoother, and their ovarian motility (bilateral), fallopian tube visualization (bilateral) and overflow condition of the contrast agent from the fimbriae of fallopian tube (bilateral) were better. In addition, the resistance of the contrast agent injection was less likely to be persistent, reflux was less likely to happen and 0/1 dispersion of the contrast agent around the ovary (bilateral) were more likely to be annular (P<0.05). Conclusions:The imaging data gathered from TV 4D HyCoSy in TFI patients were comprehensive, which suggested that TV 4D HyCoSy could have potential to be used to assess the necessity of post-HyCoSy ART intervention in patients with TFI. This could be of benefit in reducing the incidence of overtreatment and potential complications of ART.
