Association Between Subchorionic Hematoma İn The Second Trimester With Abnormal Placenta İnsertion

This study aims to evaluate the association between subchorionic hematoma (ScH) and abnormal placental insertion during the second trimester of pregnancy, focusing on its potential impact on pregnancy outcomes. A retrospective analysis was conducted on 50 patients who presented with vaginal bleeding in the second trimester and were diagnosed with ScH at an Obstetrics Department between February and August 2024. Data were collected from ultrasonography reports, clinical profiles, and medical records, specifically documenting placental abnormalities such as placenta previa and circumvallate placenta. Statistical analyses were performed using SPSS 23.0, employing both descriptive and comparative statistical tests. The study found that the mean age of the participants was 28.2 years, with an average gestational age of 25 weeks and 2 days, and a mean hematoma size of 3 cm. Abnormal placentation was identified in 4 cases, including 3 cases of placenta previa marginalist and 1 case of circumvallate placenta, with a higher mean hematoma size (2.3 cm) observed among these cases. Early pregnancy complications noted were miscarriage and partial abortion, while late complications included preterm delivery, premature rupture of membranes (PPROM), and intrauterine growth restriction. The findings suggest that ScH in the second trimester is significantly associated with abnormal placental insertion, increasing the risk of adverse outcomes such as preterm delivery and fetal growth restriction. Early detection and careful monitoring of ScH are essential for improving pregnancy outcomes. Future studies with larger sample sizes and prospective designs are recommended to further explore the relationship between ScH and placental abnormalities, as well as potential intervention strategies.
