The gestational outcome in a low-implanted gestational sac in the first trimester in primigravidae

Abstract

Background The pregnancy stage is known as implantation, when the attachment occurs between the embryo and the uterine wall. Aim This study aimed to evaluate the incidence of abortion and the gestational outcome in a low-implanted gestational sac in the first trimester in primigravidae till 28 weeks. Patients and methods The observational cohort prospective study was conducted on 100 primigravidae pregnant women with low-lying-implantation pregnancies in the first trimester. When we used the research, we omitted the patient’s name. It was only for scientific purposes that the data from this research was analyzed; it was not utilized for any other purpose. Results First-trimester bleeding, it occurred more in cases that had a gestational sac localized 0–0.5 cm from the internal ostium (OS) in 10 cases followed by cases who had a gestational sac localized more than 0.5–1 cm from the internal OS in 12 cases. Twelve cases had an abortion in the first trimester and eight cases had an abortion in the second trimester. Gestational outcome at the 28th week, 74 cases continued to the 28th week of gestation, 20 cases were aborted before the 28th week, and six cases were missed. Mode of delivery: 49 cases had cesarean section and 25 cases had normal delivery. Conclusions In primigravidas situations, the low-implanted gestational sac may increase the risk of bleeding depending on the distance from the internal OS, affecting the future position and development of the placenta with no additional risk to maternal and fetal survival.
