Abstract

Abstract

Objective To investigate the factors causing abnormal insertion of umbilical cord placenta during pregnancy, and to analyze the influence of abnormal insertion of umbilical cord placenta on pregnancy outcome. Methods A total of 15,771 pregnant women who were examined in the Ultrasound Department of The Second People’s Hospital of Yunnan Province from January 1, 2016 to January 31, 2021 were included in the observation. 879 cases of abnormal insertion ports were pathologically confirmed after delivery and were selected as the study group, and 1000 cases of normal insertion ports were randomly selected as the control group. Results Logistic regression analysis suggested multiple pregnancy history （OR = 3.34, P < 0.001）, scarred uterus （OR = 3.54, P < = 0.003）, twin pregnancy （OR = 5.25, P < 0.001）, abnormal placental position （OR = 3.47, P < 0.001）, abnormal placental morphology （OR = 8.52, P = 0.007）, in vitro embryo transfer （OR = 5.06, P < 0.001）, uterine fibroids （OR = 4.86, P < 0.001） were the risk factors for abnormal umbilical cord insertion. In terms of pregnancy outcomes, there was no significant difference between normal umbilical insertion and marginal umbilical insertion( P >0.05), but there was significant difference between normal umbilical insertion and velamentous umbilical insertion （P < 0.001）. Conclusion Multiple pregnancy history, scar uterus, twin pregnancy, abnormal placenta position, abnormal placenta morphology, in vitro embryo transfer, uterine fibroids are the high risk factors for abnormal umbilical cord insertion. For pregnancy with high-risk factors, doctors should be alert to the insertion location during prenatal ultrasound, so as to improve the prenatal diagnosis rate of abnormal insertion of the insertion mouth, especially the velamentous-like umbilical cord insertion, and improve clinical pregnancy and perinatal outcomes.
