定义
宫颈机能不全是指宫颈和子宫下段薄弱，由于宫颈不能保持妊娠至足月，可导致孕中期或妊娠晚期复发性流产。它与妊娠期宫颈提前缩短、扩张和宫颈口开放有关。提示宫颈机能不全的超声变化包括宫颈长度<1.5 cm，宫颈宽度>3 cm，宫颈管扩张>8 mm。
Cervical incompetence refers to a weakness of the cervix and lower uterine segment, which can lead to recurrent second-trimester or early third-trimester loss of pregnancy due to an inability of the uterine cervix to retain a pregnancy until term. It is associated with a premature shortening of the cervix, dilatation, and opening of the cervical os during pregnancy. Ultrasound changes that suggest cervical incompetence include a cervical length < 1.5 cm, cervical width > 3 cm, and an expanded cervical canal > 8 mm.
