Pregnancies with mean yolk sac diameter>or=5 mm on early ultrasound require monitoring and counseling about a threefold increased risk for first-trimester loss independent of maternal risk factors such as age, body mass index, polycystic ovary syndrome, smoking, and diabetes. In addition, our study shows for the first time that enlarged yolk sac diameter may be associated with an increased risk of preterm delivery.
早期超声检查中卵黄囊平均直径≥5 毫米的妊娠需要进行监测和咨询，因为其发生孕早期流产的风险增加了三倍，而与母体危险因素如年龄、体重指数、多囊卵巢综合征、吸烟和糖尿病无关。此外，我们的研究首次表明，卵黄囊直径增大可能与早产风险增加有关。
