“…As such, the role of exogenous estrogen and mechanism of SCH formation remains unclear in the infertile population. Indeed, it has been suggested that the formation of SCH is likely more complex than just estrogen and progesterone levels or protocols, and may be related to lack of the corpus luteum and factors it produces such as relaxin and vascular endothelial growth factor 15 . While our study did not account for route or dose of supplemental estrogen or progesterone, the finding that SCH did not vary by fertility treatment cycle suggests that it is also not simply related to presence of absence of a corpus luteum.…”

Objective To determine the implications of an incidentally noted subchorionic hematoma on pregnancy outcomes in the infertile population. Methods Retrospective cohort study at a tertiary care, university‐based facility. All patients with intrauterine pregnancy on initial obstetric ultrasound presenting to an infertility clinic between January 2015 and March 2018 (n = 1210), regardless of treatment cycle, were included. Nonviable pregnancies were excluded. The main outcome measured was association between subchorionic hematoma and first trimester miscarriage. Results The prevalence of subchorionic hematoma was 12.5% (n = 151) and did not differ by type of fertility treatment. There was no association between subchorionic hematoma and first trimester miscarriage; however, among patients with subchorionic hematoma, those who reported both bleeding and cramping had an increased probability of miscarriage compared to those without symptoms (0.62 vs. 0.12, P <0.001). The live birth rate in this sample was 81.3% and there were no statistically significant differences in pregnancy outcomes between those with and without subchorionic hematoma. Conclusion Among an infertile population, there was no increased risk of miscarriage when subchorionic hematoma was seen on early ultrasound; however, when patients noted both vaginal bleeding and cramping, their probability of miscarriage was significantly increased.

“…The clinical incidence rate of SCH is 0.48-39.5% ( 2 ). To date, a few studies have been conducted on the etiology and pathogenesis of SCH, mainly focusing on the following aspects: Coagulation dysfunction, immune factors, reproductive tract infections, assisted reproductive technology and drugs ( 3-5 ). Although there is ample experience in the clinical treatment of this condition, a unified treatment method does not yet exist.…”

Subchorionic hematoma (SCH) is a hematoma in which blood accumulates between the chorion and decidua basalis due to the separation of the chorion and decidua basalis. It is common in patients with threatened abortion in early pregnancy and is mainly detected by ultrasound. SCH mainly manifests as an hypoechoic or anechoic crescent-shaped fluid dark area on ultrasound images. Although there are numerous studies on SCH, its pathogenesis and etiology remain unclear, and its influence on pregnancy outcomes is also controversial; there are also no uniform clinical treatment guidelines. Current studies suggest that the occurrence of SCH may be related to several factors, such as abnormal coagulation function, autoimmune factors of pregnant women, assisted reproduction, drug use during pregnancy and reproductive tract infection; however, its exact etiology remains unclear. Some studies suggest that SCH is associated with adverse pregnancy outcomes such as miscarriage, preterm birth, preeclampsia and fetal growth restriction, although other studies have found that SCH does not increase the risk of adverse pregnancy outcomes. Therefore, the present review mainly discusses the pathogenesis, etiology and treatment of SCH in an aim to provide a reference for the clinical treatment of this condition in pregnant women.
