陈凤林教授指出:宫颈长度是4cm左右,宫颈宽度是4mm左右,都是4只是单位不同。正常单胎孕妇各不同孕周组间宫颈长度及宫颈管宽度无明显不同,均无宫颈内口开大。 Professor Chenfenglin pointed out: The length of the cervix is about 4cm, and the width o

陈凤林教授指出:宫颈长度是4cm左右,宫颈宽度是4mm左右,都是4只是单位不同。正常单胎孕妇各不同孕周组间宫颈长度及宫颈管宽度无明显不同,均无宫颈内口开大。

Professor Chenfenglin pointed out: The length of the cervix is about 4cm, and the width of the cervix is about 4mm. All 4 are different units. The length of cervix and the width of cervix tube were not significantly different among the different weeks of pregnancy in normal single pregnant women.

阴道B超测量宫颈长度和宫颈宽度,是预测先兆流晚期产和早产宫颈因素的重要手段,统计显示宫颈长度平均为(36±5)mm,宫颈管宽度为(4±1)mm。以宫颈长度≤26mm为界值,预测先兆早产孕妇发生早产的敏感性为100%,特异性为81%,阳性预测值为55%,阴性预测值为100%。

Vaginal B ultrasound measures the length and width of the cervix, which is an important means of predicting the cervical factors of late onset and premature birth. Statistics show that the average length of the cervix is(36 ± 5) mm and the width of the cervix is(4 ± 1) mm. Using the cervical length ≤ 26mm as the boundary value, the sensitivity of preterm preterm preterm preterm preterm preterm preterm was 100 %, the specificity was 81 %, the positive prediction value was 55 %, and the negative prediction value was 100 %.

宫颈过短和过宽,是宫颈机能不全的表现,陈凤林教授发明安太环,可以有效狙击晚期流产。

The cervix is too short and too wide. It is a manifestation of cervical insufficiency. Professor Chenfenglin invented the Antai ring and can effectively attack late miscarriage.
