摘　　要：目的總結臍帶真結的二維超聲聯合三維高分辨血流成像的超聲特徵。方法回顧性分析2020年10月~2022年10月經產後證實的臍帶真結的產前二維超聲及三維高分辨血流成像的聲像圖特徵。結果6例均為單胎妊娠,足月剖宮產,6例產後證實為單個臍帶真結。產前超聲表現為臍帶真結位於胎兒頸旁,臍帶局部呈結狀改變,臍帶血管自一側進入結内經旋轉、纏繞後從另一側穿出,形態固定,動態觀察及複查時結部形態無改變。結論臍帶真結的超聲表現有一定特徵性,熟悉其聲像圖特徵有助於鑒别臍帶真結與假結及其他臍帶形態異常。Objective To summarize the typical ultrasonographic features of true umbilical cord knots and improve its diagnostic accuracy rate with the use of 2D ultrasound combined with 3D HD-live Flow Technology.Methods True umbilical cord knots diagnosed by 2D ultrasound combined with 3D HD-live Flow Technology and confirmed after delivery were analyzed retrospectively from October 2020 to October 2022.Results 6 patients were singleton pregnancy and full-term born via cesarean delivery,and proved to have single true knot of umbilical cord after delivery.Prenatal ultrasound revealed that all true knots of the umbilical cord were located near the fetal neck,the umbilical cord blood vessels entered the knot from one side,rotated,entangled,and then passed out from the other side.The shape of the knots did not change during follow up and observation.Conclusion Recognizing the sonographic features of true umbilical cord knot can help to distinguish it from the false knots and other abnormalities of the umbilical cord shape.
