Abstract：Objective To investigate the pathogenesis of intrauterine fetal death(IUFD)at term pregnancy(≥37 weeks),identify critical clinical considerations,and explore effective interventions to reduce its incidence.Methods A retrospective analysis was conducted on 57 cases of term IUFD(accounting for 11.0％of perinatal mortality)within Chaoyang District,Beijing,from January 2019 to December 2023.Clinical data of all term IUFD cases were reviewed.Results Among 57 cases,52(91.2％)presented with maternal perception of abnormal fetal movement prior to IUFD.Maternal comorbidities or complications were identified in 36 cases(63.2％),including advanced maternal age(29.8％),obesity(12.3％),and gestational diabetes mellitus(10.5％).Macroscopically identifiable umbilical cord abnormalities were observed in 42 stillbirths(73.7％).Pathological examination of the fetus and adnexa revealed umbilical cord thrombosis in 5 cases.Only 2 cases showed no maternal complications or macroscopic abnormalities in the fetus or adnexa.Conclusions During late pregnancy,particularly at term,heightened attention to fetal movement monitoring is critical.Emphasis should be placed on improving awareness of fetal movement counting and recognizing abnormal patterns,especially among high-risk populations.For high-risk pregnancies with ultrasound-diagnosed severe umbilical cord abnormalities and signs of abnormal fetal movement,prompt medical intervention and timely termination of pregnancy may reduce the incidence of term IUFD.
