With the improvement of prenatal diagnoses of foetuses, the prevalence of stillbirth due to foetal anomaly after mid-gestation decreased, whereas that of stillbirth associated with umbilical cord factors tended to increase. Prenatal detection of umbilical cord abnormalities and appropriate management during the antenatal period and delivery based on the ultrasound diagnosis will improve the perinatal morbidity and mortality rates. In the present review, the strategy to reduce the incidence of foetal compromise due to umbilical cord problems is discussed considering the current knowledge regarding the physiological and pathological aspects of umbilical cord abnormalities.
随着胎儿产前诊断水平的提高，中孕期后因胎儿畸形导致的死胎发生率有所下降，而与脐带因素相关的死胎发生率则呈上升趋势。通过产前超声检查发现脐带异常，并根据检查结果在产前和分娩期进行适当的管理，可以降低围产儿发病率和死亡率。本文结合脐带异常的生理和病理知识，探讨了降低因脐带问题导致胎儿受损发生率的策略。
